Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present disclosure claims priority to Chinese Patent Application Serial No. 202322874390.2 and entitled "WIRING TERMINALS AND CONNECTOR" filed on October 25, 2023 for Chinese Patent Office, which is incorporated herein by reference in its entirety.

FIELD

[0002] The present disclosure relates to the technical field of electrical connectors, and in particular to a wiring terminal and a connector.

BACKGROUND

[0003] A wiring terminal is an accessory product for achieving electrical connection and is widely used in multiple industrial fields. A set of wiring terminals may include a male terminal and a female terminal. When the male terminal is inserted into the female terminal, a reliable electrical connection and a stable structure between the male terminal and the female terminal are ensured through various mechanical and electrical designs. In a common female terminal design, an elastic contact arm structure is arranged in the female terminal, and deformation of the elastic contact arm provides a positive pressure to a contact portion of the male terminal, so as to ensure stable contact and stable current signals between the male terminal and the female terminal.

SUMMARY

[0004] The present disclosure provides a wiring terminal and a connector, which can improve the contact stability of the wiring terminal by providing a protrusion on the inner surface of a first enclosure portion of the wiring terminal facing the second enclosure portion.

[0005] In a first aspect, the present disclosure provides a wiring terminal, including an enclosing portion, the enclosing portion having a cavity for insertion of a paired terminal; the enclosing portion includes a first enclosing portion and a second enclosing portion located on two sides of the cavity; a side of the first enclosing portion facing the second enclosing portion is provided with a protrusion, and the protrusion protrudes from the first enclosing portion toward the interior of the cavity. When the paired terminal is inserted into the wiring terminal, the protrusion can abut against the paired terminal to enhance contact stability between the paired terminal and the wiring terminal. The paired terminal interacts with the protrusion on the first enclosing portion of the wiring terminal, and the contact configuration between a top of the wiring terminal and an insertion portion of the paired terminal is established by contact between the protrusion and a surface of the paired terminal, which has a smaller contact area, so that a large contact stress can be locally formed at the contact points, thereby improving the contact stability between the paired terminal and the wiring terminal.

[0006] In a possible embodiment, a surface of the protrusion facing the second enclosing portion is an abutment surface for abutting against the paired terminal, and the abutment surface is a smooth surface. After the insertion portion of the paired terminal enters the cavity of the wiring terminal, the abutment surface of the protrusion on the top of the wiring terminal abuts against the paired terminal, and stable contact points are formed between the abutment surface and the paired terminal, enhancing the contact stability between the paired terminal and the wiring terminal.

[0007] In a possible embodiment, the protrusions are multiple. The multiple protrusions can abut against the paired terminal respectively, and the paired terminal interacts with the multiple protrusions on the top of the wiring terminal to form multiple contact points, so that a large contact stress can be locally formed at each contact point, thereby improving the contact stability between the paired terminal and the wiring terminal.

[0008] In a possible embodiment, a direction of the first enclosing portion toward the second enclosing portion is a first direction, and in the first direction, a height of the protrusion is greater than or equal to 0.05 millimeters. It is ensured that when the paired terminal is inserted and connected with the wiring terminal, the protrusions can abut against the surface of the paired terminal, and the abutment surfaces of the protrusions can form stable contact points with the surface of the paired terminal, thereby improving contact stability.

[0009] In a possible embodiment, the first enclosing portion and the protrusions are of an integrated structure. The integrally formed structure can simplify a manufacturing process of the protrusions and save costs.

[0010] In a possible embodiment, an contact arm is arranged on the second enclosing portion, and the contact arm is located in the cavity; one end of the contact arm is connected to the second enclosing portion to form a cantilever structure, and a first protruding bump is arranged on the other end of the contact arm. The insertion portion of the paired terminal interacts with the elastic contact arm and exerts abutment forces on each other, improving the contact stability between the paired terminal and the wiring terminal. The first protruding bump can contact the surface of the paired terminal after the paired terminal is inserted into the wiring terminal. The first protruding bump has a smaller contact area with the paired terminal, so that a large contact stress can be locally formed at a contact point between the first protruding bump and the paired terminal, thereby improving the contact stability between the paired terminal and the wiring terminal.

[0011] In a possible embodiment, the protrusions include a first protrusion and a second protrusion, a direction of the second enclosing portion toward the first enclosing portion is a second direction, and a projection of the first protruding bump along the second direction is located between the first protrusion and the second protrusion. Dislocation acting forces of the first protruding bump, the first protrusion and the second protrusion can improve the contact stability between the paired terminal and the wiring terminal.

[0012] In a possible embodiment, a support arm is arranged on the second enclosing portion, one end of the support arm is connected to the second enclosing portion to form a cantilever structure, a second free end of the support arm abuts against a first free end of the contact arm, and the second free end is located on a side of the first free end away from the first enclosing portion. The support arm can support the elastic contact arm and provide a supporting force toward the paired terminal to the elastic contact arm. Due to a supporting effect of the support arm on the elastic contact arm, an abutment force between the elastic contact arm and the paired terminal is greater.

[0013] In a possible embodiment, a second protruding bump is arranged on the second free end of the support arm, and the second protruding bump abuts against the first free end of the contact arm. The surface of the first free end close to the support arm abuts against the second protruding bump, and the elastic contact arm interacts with the second protruding bump on the support arm, so that a contact force between the elastic contact arm and the paired terminal is increased, thereby improving contact stability.

[0014] In a possible embodiment, the enclosing portion further includes a third enclosing portion, a part of the third enclosing portion is located between the first enclosing portion and the second enclosing portion, the third enclosing portion has an extending portion, a direction from the second enclosing portion toward the first enclosing portion is a second direction, the extending portion is bent and extends to a side of the first enclosing portion along the second direction, and the extending portion abuts against the first enclosing portion. The extending portion can abut against the top of the enclosing portion and apply an acting force toward the interior of the cavity of the enclosing portion to the top of the enclosing portion, preventing the enclosing portion of the wiring terminal from being pushed open by the paired terminal when the paired terminal is inserted, and enhancing structural stability of the wiring terminal.

[0015] In a possible embodiment, the extending portion includes a bending portion, the bending portion protrudes from the first enclosing portion toward the second direction, and the bending portion abuts against the first enclosing portion. The extending portion protrudes from the first enclosing portion toward the second direction to form the bending portion, and the bending portion has a foolproof function, ensuring that the wiring terminal can be inserted into a protective sleeve only in a correct configuration when connected to the protective sleeve.

[0016] In a possible embodiment, the extending portions are multiple, the multiple extending portions are spaced apart along a third direction, the third direction is an extending direction of the cavity and perpendicular to the second direction, and the extending portion close to an insertion opening of the cavity includes the bending portion.

[0017] In a possible embodiment, the wiring terminal further includes a wire clamping portion, the wire clamping portion is connected to the enclosing portion, the wire clamping portion includes a first wire clamping portion and a second wire clamping portion, one end of the first wire clamping portion is connected to or integrated with one end of the second wire clamping portion, and the other end of the first wire clamping portion and the other end of the second wire clamping portion approach each other to form a groove-shaped structure. A connecting wire connected to the wiring terminal can be accommodated between the first wire clamping portion and the second wire clamping portion, and the connecting wire is compressed between the first wire clamping portion and the second wire clamping portion, so that the connecting wire and the wiring terminal are connected to each other.

[0018] In a possible embodiment, a groove is arranged on the wire clamping portion; the groove is arranged on a surface of the first wire clamping portion close to the second wire clamping portion, and/or the groove is arranged on a surface of the second wire clamping portion close to the first wire clamping portion. The groove is used for accommodating an electric wire so as to increase a holding force between the wire clamping portion and the electric wire. The groove can accommodate the connecting wire connected to the wiring terminal so as to increase the holding force between the wire clamping portion and the connecting wire. The connecting wire is crimped between the first wire clamping portion and the second wire clamping portion, a part of the electric wire is squeezed into the groove, and a friction force between the electric wire and the wire clamping portion is increased, thereby improving the holding force between the wire clamping portion and the electric wire.

[0019] In a second aspect, the present disclosure further provides a connector, the connector includes the wiring terminal according to any one of the above embodiments, and the connector further includes a paired terminal matching with the wiring terminal, the paired terminal being inserted into the cavity of the wiring terminal. The paired terminal and the wiring terminal are connected by insertion, and the insertion portion of the paired terminal can enter the wiring terminal, so as to realize a reliable electrical connection between the paired terminal and the wiring terminal.

[0029] In the prior art, a top contact surface of a female terminal is usually a flat surface, and contact with a male terminal is surface-to-surface contact, which has a risk of poor contact.

[0030] The present disclosure provides a wiring terminal. Referring to FIG. 1, the wiring terminal 10 provided by the present disclosure includes an enclosing portion 100, the enclosing portion 100 has a cavity 200, and the cavity 200 can accommodate an insertion portion of a paired terminal. In the present disclosure, the wiring terminal 10 is taken as a female terminal and the paired terminal is taken as a male terminal for illustration. When the male terminal and the female terminal are connected by insertion, the insertion portion of the male terminal can enter the cavity 200 of the female terminal, so as to realize contact electrical connection between the male terminal and the female terminal. It will be noted that in the present disclosure, the name "female terminal" only represents a conventional definition in the field of electrical connectors, and does not represent a specific limitation on the terminal structure.

[0031] In a possible embodiment, referring to FIGS. 1 to 5, the enclosing portion 100 in the embodiment of the present disclosure includes a first enclosing portion 110 and a second enclosing portion 120 located on two sides of the cavity 200. In the present disclosure, the enclosing portion 100 is taken as a square enclosing structure shown in FIG. 1 for illustration. In FIGS. 1 and 2, the first enclosing portion 110 is located on the side of the Z-direction of the cavity 200, and the second enclosing portion 120 is located on the side of opposite Z-direction of the cavity 200. The enclosing portion 100 may be a square cylindrical structure, the first enclosing portion 110 may be a top of the square cylindrical structure, and the second enclosing portion 120 may be a bottom of the square cylindrical structure.

[0032] Referring to FIG. 2, a side of the first enclosing portion 110 facing the second enclosing portion 120 is arranged with a protrusion 111, that is, a surface of the first enclosing portion 110 on the side of opposite Z-direction in FIG. 2 is arranged with the protrusion 111. The protrusion 111 protrudes from the first enclosing portion 110 toward the interior of the cavity 200, that is, a protruding direction of the protrusion 111 is consistent with the opposite Z-direction in FIG. 2. It will be noted that, for convenience of showing the internal structure, one side wall of the female terminal is omitted in FIG. 2, which does not represent a limitation on the structure of the female terminal.

[0033] By arranging the protrusion 111 on the surface of the first enclosing portion 110 on the side facing the second enclosing portion 120, when the male terminal is inserted into the female terminal along the Y-direction, the protrusion 111 can abut against the male terminal, enhancing the contact stability between the male terminal and the female terminal. Specifically, after the insertion portion of the male terminal enters the cavity 200 of the female terminal, as the male terminal moves along the insertion direction, a surface of the male terminal in the Z-direction abuts against the protrusion 111, the protrusion 111 has an abutment force on the insertion portion of the male terminal in the opposite Z-direction, and the insertion portion of the male terminal also has an abutment force in the Z-direction on the protrusion 111. The male terminal interacts with the protrusion 111 on the top of the female terminal, so that the connection between the male terminal and the female terminal is more stable.

[0034] When an inner surface of the top of the female terminal is a flat structure, that is, when no protrusion 111 is arranged, the insertion portion of the male terminal enters the cavity 200 of the female terminal, the male terminal moves along the insertion direction, and the surface of the male terminal in the Z-direction is directly contact with the surface of the top of the female terminal on the opposite Z-direction side. At this time, the contact configuration between the male terminal and the female terminal is established by surface-to-surface contact. In the embodiment of the present disclosure, the protrusion 111 is arranged on the top of the female terminal, and the contact configuration between the top of the female terminal and the insertion portion of the male terminal is established by contact between the protrusion 111 and the surface of the male terminal, that is, point contact, which has a smaller contact area, so that a large contact stress can be locally formed at the contact point, thereby improving the contact stability between the male terminal and the female terminal.

[0035] In a possible embodiment, referring to FIGS. 2 to 5, a surface of the protrusion 111 facing the second enclosing portion 120 in the embodiment of the present disclosure is an abutment surface 121, and the abutment surface 121 is a smooth surface. The abutment surface 121 being a smooth surface means that the abutment surface 121 is a continuously transitional surface, for example, an arc transitional surface, and the abutment surface 121 has no sharp ends. Of course, the abutment surface 121 may also be other smooth surfaces, such as a hemispherical surface or a semi-ellipsoidal surface. Here, that the abutment surface 121 being a smooth surface only limits that the abutment surface 121 has no sharp ends, so as to avoid problems such as damage to the male terminal or causing poor contact during insertion.

[0036] When the male terminal and the female terminal are inserted, the insertion portion of the male terminal enters the cavity 200 of the female terminal. The male terminal moves along the insertion direction, the surface of the male terminal in the Z-direction contacts the abutment surface 121 of the protrusion 111, the protrusion 111 has an acting force on the male terminal in a direction away from the first enclosing portion 110, and the abutment surface 121 of the protrusion 111 on the top of the female terminal abuts against the male terminal. Under the interaction of forces between the protrusion 111 and the male terminal, a stable contact point is formed between the abutment surface 121 and the male terminal, and a large contact stress is generated at the local contact area, enhancing the contact stability between the male terminal and the female terminal.

[0037] In a possible embodiment, referring to FIGS. 2 and 3, there may be multiple protrusions 111 in the embodiment of the present disclosure, for example, two protrusions 111 may be arranged, or three or more protrusions 111 may be arranged in some possible embodiments. In the embodiment of the present disclosure, two protrusions 111 are taken as an example for illustration.

[0038] Referring to FIG. 3, which is a cross-sectional view of the female terminal provided by the embodiment of the present disclosure, two protrusions 111 may be arranged on a surface of the top of the female terminal inside the cavity 200, that is, two protrusions 111 are arranged on the surface of the first enclosing portion 110 on the side of opposite Z-direction in FIG. 3, and the protrusions 111 protrude from the first enclosing portion 110 toward the interior of the cavity 200. After the insertion portion of the male terminal enters the cavity 200 of the female terminal, a surface of the male terminal on the side of the Z-direction abuts against the protrusion 111 close to the socket, and as the male terminal moves along the insertion direction, the surface of the male terminal on the side of the Z-direction abuts against both protrusions 111. Both protrusions 111 have abutment forces on the insertion portion of the male terminal in opposite Z-direction, and at the same time, the insertion portion of the male terminal also have abutment forces in the Z-direction on both protrusions 111. The male terminal interacts with the multiple protrusions 111 on the top of the female terminal to form multiple contact points, and a large contact stress can be locally formed at each contact point, thereby improving the contact stability between the male terminal and the female terminal.

[0039] The two protrusions 111 arranged on the first enclosing portion 110 may be connected or close to each other, a single protrusion 111 may be approximately V-shaped or U-shaped, and the two protrusions 111 may form a shape approximately similar to the letter W. Both protrusions 111 have abutment surfaces 121, and when the male terminal is inserted into the female terminal, both abutment surfaces 121 can abut against the male terminal. Each abutment surface 121 can abut against the surface of the male terminal to form a stable contact point, and the two protrusions 111 respectively contact the surface of the male terminal to improve contact stability.

[0040] In a possible embodiment, the first enclosing portion 110 and the protrusions 111 in the embodiment of the present disclosure are of an integrated structure. For example, the protrusions 111 may be manufactured by a stamping process. In FIGS. 1 and 2, a surface of the first enclosing portion 110 away from the cavity 200, that is, a surface of the first enclosing portion 110 on the side of the Z-direction is arranged with a recess, which may be formed during the stamping process for producing the protrusions 111. The protrusions 111 are pre-stamped at a top wall portion of the female terminal to ensure that the protrusions 111 are located on the surface of the first enclosing portion 110 inside the cavity 200 after the terminal is manufactured. The integrated forming method can simplify the manufacturing process of the protrusions 111 and save costs.

[0041] In a possible embodiment, referring to FIG. 3, the direction of the first enclosing portion 110 toward the second enclosing portion 120 in the embodiment of the present disclosure is a first direction 610, that is, the direction from the top to the bottom of the female terminal. In FIG. 3, the first direction 610 is parallel to the opposite Z-direction. In the first direction 610, a height of the protrusion 111 arranged on the inner surface of the top of the female terminal is greater than or equal to 0.05 mm. The size of the protrusion 111 is not specifically limited here, and only indicates that the protrusion 111 can abut against the surface of the male terminal while ensuring insertion connection between the male terminal and the female terminal in use. The abutment surface 121 of the protrusion 111 can form a stable contact point with the surface of the male terminal, thereby improving contact stability. Those of ordinary skill in the art can flexibly set the size of the protrusion 111 according to actual use requirements.

[0042] In a possible embodiment, referring to FIGS. 2 and 3, an elastic contact arm 300 is arranged on the second enclosing portion 120 in the embodiment of the present disclosure, and the elastic contact arm 300 is located in the cavity 200. One end of the elastic contact arm 300 is fixedly connected to the second enclosing portion 120 to form a cantilever structure. The elastic contact arm 300 may be integrated with the second enclosing portion 120. For example, in FIG. 2, the elastic contact arm 300 may be formed by bending a bottom of the female terminal toward the Z-direction into the cavity 200.

[0043] The other end of the elastic contact arm 300 is referred to as a first free end 310 of the elastic contact arm 300. When the male terminal is inserted into the female terminal, the male terminal contacts the elastic contact arm 300 and has an acting force on the elastic contact arm 300 in the direction of opposite to the Z-direction. With insertion of the male terminal, the elastic contact arm 300 is subjected to a pressing force of the male terminal, and the first free end 310 of the elastic contact arm 300 moves downward, that is, the first free end 310 moves toward a direction close to the second enclosing portion 120. Since the elastic contact arm 300 has elasticity, the elastic contact arm 300 tends to return to its original state, and the elastic contact arm 300 exerts an acting force in the Z-direction on the insertion portion of the male terminal. The insertion portion of the male terminal interacts with the elastic contact arm 300 and exerts abutment forces on each other, thus improving the contact stability between the male terminal and the female terminal.

[0044] In a possible embodiment, referring to FIGS. 2 and 3, the first free end 310 is arranged with a first protruding bump 311, and the first protruding bump 311 can contact the surface of the male terminal after the male terminal is inserted into the female terminal.

[0045] When the male terminal is inserted into the female terminal, the male terminal contacts the first protruding bump 311 arranged on the first free end 310 and has an acting force on the first protruding bump 311 in the opposite Z-direction. The first protruding bump 311 is subjected to the pressing of the male terminal, and the first protruding bump 311 together with the first free end 310 moves toward the second enclosing portion 120. Meanwhile, the first protruding bump 311 also exerts an acting force on the insertion portion of the male terminal in the Z-direction. The surface of the male terminal in the Z-direction abuts against the first protruding bump 311, and the male terminal interacts with the protrusion 111 on the top of the female terminal, so that the connection between the male terminal and the female terminal is more stable.

[0046] The first protruding bump 311 is arranged on the first free end 310, and a contact configuration between the elastic contact arm 300 and the insertion portion of the male terminal is established by contact between the first protruding bump 311 and the surface of the male terminal. Compared with a configuration in which the elastic contact arm 300 directly contacts the male terminal, the contact area between the first protruding bump 311 and the male terminal is smaller, so that a large contact stress can be locally formed at a contact point between the first protruding bump 311 and the male terminal, thereby improving the contact stability between the male terminal and the female terminal.

[0047] In a possible embodiment, referring to FIG. 3, the protrusion 111 includes a first protrusion 111a and a second protrusion 111b, and the direction from the second enclosing portion 120 toward the first enclosing portion 110 is a second direction 620, and the second direction 620 is parallel to the direction of Z-axis in FIG. 3. A projection of the first protruding bump 311 along the second direction 620 is located between the first protrusion 111a and the second protrusion 111b, as shown by a dotted line in FIG. 3. That is, the first protruding bump 311 on the elastic contact arm 300 is located below a position between the first protrusion 111a and the second protrusion 111b (in FIG. 3, the direction of Z-axis is upward, and the opposite direction of Z-axis is downward). The first protruding bump 311 is arranged below the position between the first protrusion 111a and the second protrusion 111b, so that when the male terminal is inserted into the female terminal, the male terminal can be better abutted by combined acting forces of the first protruding bump 311, the first protrusion 111a and the second protrusion 111b, thereby improving the contact stability between the male terminal and the female terminal.

[0048] In a possible embodiment, referring to FIGS. 2 and 3, a support arm 400 is arranged on the second enclosing portion 120 in the embodiment of the present disclosure, one end of the support arm 400 is connected to the second enclosing portion 120 to form a cantilever structure. The other end of the support arm 400 is referred to as a second free end 410 of the support arm 400, and the second free end 410 of the support arm 400 abuts against the first free end 310 of the elastic contact arm 300, and the second free end 410 is located on the side of the first free end 310 away from the first enclosing portion 110.

[0049] The support arm 400 may be integrated with the second enclosing portion 120. For example, in FIGS. 2 and 3, the support arm 400 may be formed by bending the bottom of the female terminal, that is, the second enclosing portion 120. A configuration in which the support arm 400 is formed by bending the second enclosing portion 120 does not require additional mold design and can save manufacturing costs.

[0050] In FIGS. 2 and 3, the second free end 410 of the support arm 400 is located below the first free end 310 of the elastic contact arm 300, that is, the second free end 410 is located in the opposite Z-direction of the first free end 310. When the male terminal is inserted into the female terminal along the Y-direction, the insertion portion of the male terminal presses the elastic contact arm 300, the elastic contact arm 300 moves downward under the acting force of the male terminal, and the elastic contact arm 300 presses the support arm 400 when moving downward. While the support arm 400 is pressed by the elastic contact arm 300, the support arm 400 supports the elastic contact arm 300, that is, the support arm 400 exerts a supporting force toward the Z-direction on the elastic contact arm 300. The elastic contact arm 300 is pressed by the male terminal on the one hand and supported by the support arm 400 on the other hand. Due to the supporting effect of the support arm 400 on the elastic contact arm 300, an abutment force between the elastic contact arm 300 and the male terminal is greater.

[0051] Providing the support arm 400 on the second enclosing portion 120 can improve the abutment force between the elastic contact arm 300 and the male terminal and improve contact stability. In addition, the support arm 400 in the present embodiment can be formed by bending the bottom of the female terminal, without requirement of a separate part mold design or additional assembly, and the manufacturing process is simple and can save costs.

[0052] In a possible embodiment, referring to FIG. 3, the second free end 410 of the support arm 400 is arranged with a second protruding bump 411, and the second protruding bump 411 can abut against the first free end 310 of the elastic contact arm 300.

[0053] When the male terminal is inserted into the female terminal, the male terminal contacts the first free end 310 of the elastic contact arm 300 and has an acting force in the opposite Z-direction on the first free end 310. The first free end 310 moves toward a direction close to the support arm 400 after being pressed by the male terminal. The first free end 310 of the elastic contact arm 300 contacts the second free end 410 of the support arm 400. Since the second free end 410 is arranged with the second protruding bump 411, the first free end 310 abuts against the second protruding bump 411 on the second free end 410, and the first free end 310 exerts an acting force in the opposite Z-direction on the second protruding bump 411. Meanwhile, the second protruding bump 411 also has an acting force in the Z-direction on the first free end 310. A surface of the first free end 310 close to the support arm 400 abuts against the second protruding bump 411, and the elastic contact arm 300 interacts with the second protruding bump 411 on the support arm 400, so that a contact force between the elastic contact arm 300 and the male terminal is increased, thereby improving the contact stability.

[0054] The second protruding bump 411 is arranged on the second free end 410, and a contact configuration between the support arm 400 and the elastic contact arm 300 is that the second protruding bump 411 contacts a surface of the elastic contact arm 300 close to the support arm 400, that is, the second protruding bump 411 abuts against a lower surface of the elastic contact arm 300, and a large contact stress is locally formed at the contact point. Meanwhile, the support arm 400 can also provide a force required for the elastic contact arm 300 to abut against the male terminal, thereby improving the contact stability between the male terminal and the female terminal.

[0055] In a possible embodiment, referring to FIGS. 1 to 5, the enclosing portion 100 in the embodiment of the present disclosure further includes a third enclosing portion 130, and a part of the third enclosing portion 130 is located between the first enclosing portion 110 and the second enclosing portion 120. The third enclosing portion 130 has an extending portion 131, the direction of the second enclosing portion 120 toward the first enclosing portion 110 is a second direction 620, the extending portion 131 is bent and extends to a side of the first enclosing portion 110 along the second direction 620, and the extending portion 131 abuts against the first enclosing portion 110.

[0056] The extending portion 131 and the third enclosing portion 130 may be of an integrated structure. Referring to FIGS. 1 and 2, the extending portion 131 may be formed by bending the side wall of the enclosing portion 100, and the bent side wall of the enclosing portion 100 abuts against the first enclosing portion 110. That is, in FIGS. 1 and 2, the side wall of the female terminal is bent and abuts against the top of the female terminal in the Z-direction. When the male terminal is inserted, the surrounding wall surfaces of the female terminal may be subjected to an acting force, causing the surrounding wall surfaces of the female terminal to be pushed open. In the embodiment of the present disclosure, the extending portion 131 can abut against the top of the enclosing portion 100 and apply an acting force toward the interior of the cavity of the enclosing portion 100 to the top of the enclosing portion 100, preventing the enclosing portion 100 of the female terminal from being pushed open by the male terminal when the male terminal is inserted, and enhancing structural stability of the female terminal. Meanwhile, the extending portion 131 and the side wall of the enclosing portion 100 may be made of the same plate and directly formed by bending the side wall of the female terminal, and the manufacturing method is simple.

[0057] In a possible embodiment, referring to FIGS. 1 to 3, the extending portion 131 includes a bending portion 1311, the bending portion 1311 protrudes from the first enclosing portion 110 toward the second direction 620, and the bending portion 1311 abuts against the first enclosing portion 110. The bending portion 1311 may be formed by protruding the extending portion 131 to a certain height toward the Z-direction in FIG. 1, and a gap may be arranged between the bending portion 1311 and the first enclosing portion 110 so that the bending portion 1311 protrudes toward the Z-direction in FIG. 1.

[0058] During use of the wiring terminal 10, the wiring terminal 10 can be inserted into a protective sleeve, and the bending portion 1311 can play a foolproof role. That is, a slot matching the shape of the bending portion 1311 may be arranged in the protective sleeve, and the operator can only match the bending portion 1311 with the slot on the protective sleeve in a unique insertion direction when using the wiring terminal 10. By means of the foolproof structure, namely the bending portion 1311, the connection direction of the wiring terminal 10 can be quickly determined to be a correct direction, thus improving installation efficiency of the wiring terminal 10.

[0059] In a possible embodiment, referring to FIG. 2, there may be multiple extending portions 131, the multiple extending portions 131 are spaced apart along a third direction 630, and the third direction 630 is an extending direction of the cavity 200. In FIG. 2, the third direction 630 is parallel to the Y-direction. That is, the multiple extending portions 131 are spaced apart along the direction parallel to the Y-axis, and the extending portion 131 close to the insertion opening 201 of the cavity 200 may be the bending portion 1311. If the insertion configuration is incorrect, the bending portion 1311 will prevent the wiring terminal 10 from being inserted into the protective sleeve, and the bending portion 1311 at the insertion opening 201 can ensure that the wiring terminal 10 can be inserted into the protective sleeve only in a unique correct configuration.

[0060] In a possible embodiment, referring to FIGS. 1 to 5, the female terminal in the embodiment of the present disclosure further includes a wire clamping portion 500, the wire clamping portion 500 is fixedly connected to the enclosing portion 100, or the wire clamping portion 500 may also be an integrated structure with the enclosing portion 100, that is, the wire clamping portion 500 and the enclosing portion 100 may be integrally formed from the same plate, simplifying the manufacturing process and making the connection more reliable.

[0061] The wire clamping portion 500 may include a first wire clamping portion 510 and a second wire clamping portion 520, one end of the first wire clamping portion 510 is connected to one end of the second wire clamping portion 520, or one end of the first wire clamping portion 510 and one end of the second wire clamping portion 520 may also be an integrated structure. The other end of the first wire clamping portion 510 and the other end of the second wire clamping portion 520 approach each other to form a U-shaped structure as shown in FIG. 1. A connecting wire connected to the female terminal can be accommodated between the first wire clamping portion 510 and the second wire clamping portion 520, the first wire clamping portion 510 and the second wire clamping portion 520 approach each other, and the connecting wire is compressed between the first wire clamping portion 510 and the second wire clamping portion 520, so that the connecting wire is connected to the female terminal.

[0062] In a possible embodiment, a groove 530 may be arranged on the wire clamping portion 500 in the embodiment of the present disclosure. The groove 530 is arranged on a surface of the first wire clamping portion 510 close to the second wire clamping portion 520, or the groove 530 is provided on a surface of the second wire clamping portion 520 close to the first wire clamping portion 510, or grooves 530 may be arranged on both the first wire clamping portion 510 and the second wire clamping portion 520. The groove 530 accommodates the connecting wire connected to the female terminal so as to increase a holding force between the wire clamping portion 500 and the connecting wire. When the connecting wire is crimped between the first wire clamping portion 510 and the second wire clamping portion 520, a part of the electric wire is squeezed into the groove 530, and a friction force between the electric wire and the wire clamping portion 500 is increased, thereby improving the holding force between the wire clamping portion 500 and the electric wire.

[0063] In a possible embodiment, referring to FIG. 5, the present disclosure further provides a connector, the connector includes the wiring terminal 10 according to any one of the above embodiments, and the connector further includes a paired terminal 20 matching with the wiring terminal 10, the paired terminal 20 being inserted into the cavity 200 of the wiring terminal 10.

When the male terminal and the female terminal are connected by insertion, the insertion portion of the male terminal can enter the female terminal, so as to realize a reliable electrical connection between the male terminal and the female terminal.

[0064] The above embodiments are only used to illustrate the technical solutions of the present disclosure, but not to limit them. Although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art will understand that they can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions depart from the spirit and scope of the technical solutions of the embodiments of the present disclosure, and shall be included in the protection scope of the present disclosure.
