Description

TECHNICAL FIELD

[0001] The present invention relates to the field of wiring of electrical equipment, and in particular, to a wiring device for a switch socket.

BACKGROUND

[0002] Currently, switch sockets are widely used because they have the function of controlling circuits of household appliances to be opened or closed. The plug of an appliance can contact a copper sheet of a socket so that the socket can supply power to the appliance. A switch can connect a circuit wire of the appliance to the power conducting copper sheet, so that the on-state of the circuit of the appliance can be controlled by the switching action of the switch.

[0003] A switch socket on the market generally uses a screw or a spring to connect a wire and a power conducting copper sheet on the switch socket. However, the screwing process is time-consuming. If a large number of wires need to be connected, a large amount of time is required in the screwing process, resulting in low wiring efficiency.

[0004] There are various types of wires on the market. If a wire is a copper wire with a relatively large diameter, the copper wire is relatively hard, and if a screw is used to fix the copper wire with a relatively large diameter, the copper wire may be loosened due to vibration. If the wire is wound from a large number of copper wires with a smaller diameter, the copper wires in contact with the screw may be easily broken during wiring due to the relatively soft texture of the copper wires, and stability of the circuit is also poor.

[0005] Further, the use of a spring-type wiring product can prevent the copper wire with a larger diameter from being loosened after being vibrated, so that the wiring is more reliable, and the spring-type wiring product can be applied to more scenarios. However, a conventional spring-type structure generally has the following disadvantages: When a wire enters an existing switch socket, an external force is required to forcibly push the wire into a pressing structure in the switch socket, and the friction between the wire and the pressing structure is relatively large, which prevents the wire from being removed from the switch socket. In addition, if the wire is wound from a large number of fine copper wires, the wire cannot be pushed into the pressing structure due to its insufficient hardness, and the contact is poor.

SUMMARY

[0006] To overcome the disadvantages of the prior art, it is an objective of the present invention to provide a wiring device for a switch socket, which is suitable for different types of wires, so that the wires can enter and leave the switch socket smoothly, damage to the wires is reduced, and quick wiring is achieved.

DESCRIPTION OF EMBODIMENTS

[0020] In the following, the present invention will be further described with reference to the accompanying drawings and specific implementations. It should be noted that, provided that there is no conflict, the following embodiments or technical features can be combined to form new embodiments.

First Embodiment

[0021] A wiring device for a switch socket is applied to a switch or a socket, is compatible with different types of wires 6, can reduce damage to the wires 6 during wiring, and allows the wires 6 to enter and leave the switch socket smoothly, thereby achieving quick wiring.

[0022] As shown in FIG. 1 to FIG. 6, the wiring device includes a base 1, where a power conducting plate 5 and a switch circuit are provided inside the base 1, and the power conducting plate 5 is connected to the switch circuit. When the wire 6 is connected to the power conducting plate 5, an appliance corresponding to the wire 6 can be connected to the switch circuit, so that a circuit of the household appliance can be controlled to be opened or closed.

[0023] The base 1 is provided with a plurality of positioning members 2, where each of the positioning members 2 is provided with at least one cavity 21 for accommodating the wire 6, and the plurality of positioning members 2 may be provided on both sides of the base 1, so that connected wires 6 are orderly arranged.

[0024] In this embodiment, two cavities 21 are provided in the positioning member 2, that is, two wires 6 can be connected to the same positioning member 2, and the two wires 6 are secured by using the same lever 3, so that wiring efficiency is improved.

[0025] A clamping rail 22 is provided between the two cavities 21 of the positioning member 2, and a lever 3 is mounted on the clamping rail 22, so that the lever 3 can be limited in the clamping rail 22 during rotation, thereby preventing the lever 3 from moving and falling off. The lever 3 includes an operating end 31 and an abutment end 33, where horizontal stripes are provided on a surface of the operating end 31 to increase friction on the surface of the operating end 31. A swing rod 32 extends from the middle of the operating end 31 toward the clamping rail 22, and an end of the swing rod 32 is inserted into the clamping rail 22; and a rotating shaft is provided in the clamping rail 22, and the end of the swing rod 32 is sleeved on the rotating shaft. In this way, a hinged connection between the lever 3 and the positioning member 2 is achieved, so that the lever 3 can rotate relative to the positioning member 2. The lever 3 is hinged to the positioning member 2, and the lever 3 can be rotated by 0°-90°. When the lever 3 is rotated by 0°, the operating end 31 is in a flat state. When the lever 3 is rotated by 90°, the operating end 31 is in a lifting limit state, and the abutment end 33 can rotate to the lowest point.

[0026] The abutment end 33 is provided on each side of the operating end 31, and the abutment end 33 can be pressed toward the wiring terminal 4 located below the abutment end 33 during rotation, so that the wiring terminal 4 elastically deforms to separate the wiring terminal 4 from the wire 6, thereby enabling the wire 6 to enter and leave the cavity 21 smoothly, and preventing the wire 6 from being damaged.

[0027] The abutment end 33 includes a curved arc portion 331 and an abutment portion 332, where the curved arc portion 331 and the abutment portion 332 are integrally formed. An upper edge of the curved arc portion 331 is in a horizontal state, so that the upper edge of the curved arc portion 331 is parallel to a horizontal inner side wall of the positioning member 2. In this way, when the lever 3 is in a flat state, the upper edge of the curved arc portion 331 abuts against the horizontal inner side wall of the positioning member 2, so that when the lever 3 is in a flat state, a downward pressing angle of the lever 3 is limited. The curved arc portion 331 is provided as a curved arc plate structure, and a curvature of an outer edge of the curved arc portion 331 is greater than a curvature of an inner edge of the curved arc portion 331, so that the abutment portion 332 can extend toward the inside of the base 1 when the lever 3 is in a flat state, and the end point of the abutment portion 332 is not located on a middle line of the upper edge of the curved arc portion 331 (line O in FIG. 4), but extends away from the middle line O of the upper edge of the curved arc portion 331, and extends toward the power conducting plate 5. In this way, a length of the abutment end 33 can be increased within a limited space in the switch socket, so that when the abutment end 33 is rotated, the abutment portion 332 can abut against the wiring terminal 4 and press downward the elastic member 42 in the wiring terminal 4 by a sufficient depth. Therefore, the contact portion 41 of the wiring terminal 4 is separated from the wire 6, and the wire 6 can enter and leave the cavity 21 smoothly.

[0028] Further, a limiting block 23 having an inverted trapezoidal structure is provided on the horizontal inner side wall of the positioning member 2, and the limiting block 23 is configured to limit a swing amplitude of the lever 3. When the lever 3 is lifted to the highest point, the upper edge of the curved arc portion 331 abuts against a side of the limiting block 23. In this case, the abutment portion 332 is at the lowest point, so that the abutment portion 332 abuts against the groove 43 and presses the elastic member 42 to the lowest point to maximize the distance between the contact portion 41 and the wire 6. When the lever 3 is in a flat state, the upper edge of the curved arc portion 331 abuts against a bottom edge of the limiting block 23, and the abutment end 33 is separated from the elastic member 42, so that the contact portion 41 directly presses the wire 6.

[0029] The wiring terminal 4 is provided in a gap between the cavity 21 and the positioning member 2 of the power conducting plate 5. As shown in FIG. 4, the wiring terminal 4 includes an elastic member 42 in contact with the power conducting plate 5 and a contact portion 41 for pressing the wire 6. The elastic member 42 has a U-shaped structure. The elastic member 42 includes a first planar portion 421, a second planar portion 422, and an arc portion 423. Both ends of the arc portion 423 are connected to the first planar portion 421 and the second planar portion 422, respectively, so that the first planar portion 421 and the second planar portion 422 are sequentially distributed up and down between the wire 6 and the power conducting plate 5. A U-shaped opening of the elastic member 42 is facing the power conducting plate 5, and an outer surface of the arc portion 423 abuts against an inner side wall of the positioning member 2, so that the wiring terminal 4 has certain elasticity under the action of an external force.

[0030] The upper end portion of the elastic member 42 extends obliquely upward to form the contact portion 41. When the elastic member 42 is not subjected to an external force, the elastic force of the elastic member 42 causes the contact portion 41 to abut against the wire 6 in the cavity 21, so that the circuit is connected. When the elastic member 42 is pressed downward by an external force, the contact portion 41 can be driven away from the wire 6, so that the circuit is disconnected.

[0031] Both sides of the elastic member 42 are recessed downward to form a groove 43, and the groove 43 corresponds to the abutment end 33. When the operating end 31 is rotated and lifted with respect to the positioning member 2, the abutment end 33 is driven to rotate to the lowest point to abut against the groove 43, and the elastic member 42 is pressed down to separate the contact portion 41 from the wire 6. The structure of the groove 43 corresponds to the structure of the abutment portion 332, and the side of the groove 43 is always connected to the first planar portion 421, so that the structure of the groove 43 is more stable, the abutment end 33 abuts against the elastic member 42 more stably, and displacement is avoided.

[0032] A power conducting plate 5 having a Z-shaped structure is provided behind the cavity 21. The power conducting plate 5 includes a first connecting portion 51, a connecting rod 52, and a second connecting portion 53. The first connecting portion 51 and the second connecting portion 53 are parallel to each other, and the first connecting portion 51 and the second connecting portion 53 are connected with at least two vertical connecting rods 52 therebetween. The connecting rod 52 forms an angle of 60°-90° with the first connecting portion 51 and the second connecting portion 53, respectively. In this embodiment, the connecting rod 52 forms an angle of 60° with the first connecting portion 51 and the second connecting portion 53, respectively. There is a certain gap between adjacent connecting rods 52 for accommodating the wire 6 and the contact portion 41, and notches 411 are provided on both sides of the contact portion 41, so that the contact portion 41 is accommodated between the two adjacent connecting rods 52. This prevents an edge of the contact portion 41 from rubbing against the connecting rods 52 when the contact portion 41 moves up and down, thereby extending the service life of the connecting rods 52 and the contact portion 41.

[0033] The first connecting portion 51 is connected to the switch circuit in the base 1, and the second connecting portion 53 extends directly below the second planar portion 422, so that the second planar portion 422 and the second connecting portion 53 are sequentially stacked up and down and are in close contact, thereby increasing a contact area between the wiring terminal 4 and the power conducting plate 5, and reducing the contact resistance.

[0034] The second connecting portion 53 abuts against the positioning member 2 in the horizontal direction, and a limiting hole is formed in a surface of the second connecting portion 53. A bending piece 44 is provided in the middle of the second planar portion, and the bending piece 44 extends downward through the limiting hole to limit movement of the elastic member 42 in the horizontal direction, so as to secure the wiring terminal 4.

[0035] The operating principle of this embodiment is as follows:
As shown in FIG. 5, when a user lifts the lever 3 to the highest point, the abutment portion 332 is clamped in the groove 43, and the elastic member 42 is pressed down to the lowest point, so that the distance between the contact portion 41 and the wire 6 is maximized. In this case, the wire 6 can be inserted into the base 1 from the cavity 21 until the wire 6 penetrates through the gap between the two adjacent connecting rods 52 on the power conducting plate 5, or the wire 6 is retracted from the base 1. Then, the user can put the lever 3 down to a flat state, the abutment end 33 is separated from the elastic member 42, and the elastic member 42 causes the contact portion 41 to press toward the wire 6 in an elastic force recovery process, so that the wire 6 contacts the wiring terminal 4 and is connected to the switch circuit through the power conducting plate 5, thereby achieving the effect of controlling the circuit of an appliance.

[0036] When the lever 3 is rotated, the abutment end 33 is driven to rotate, and the abutment end 33 abuts against the groove 43 when rotating to the lowest point, and the elastic member 42 is pressed down to separate the contact portion 41 from the wire 6, so that the wire 6 quickly enters or leaves the cavity 21 smoothly, and the wire 6 is not damaged during wiring. In addition, the wiring device is compatible with different types of wires 6, and quick wiring can be achieved whether the wire 6 is made of a soft material or the wire 6 is a hard copper wire.

Second Embodiment

[0037] As shown in FIG. 7 and FIG. 8, based on the first embodiment, the number of the cavities 21 in the positioning member 2 is set to one, that is, one of the positioning members 2 corresponds to one of the cavities 21. A clamping rail 22 is provided on the upper surface of the positioning member 2, and the lever 3 is hinged to the clamping rail 22, so that the lever 3 rotates with respect to the positioning member 2 to drive the abutment end 33 to rotate and abut against the elastic member 42, so that the elastic member 42 deforms, the wire 6 enters and leaves the switch socket smoothly, and quick wiring is achieved.

[0038] The remaining parts in this embodiment are described in detail in the first embodiment. Therefore, the structure of this embodiment and the connection relationship thereof will be clearly understood by those skilled in the art based on the foregoing description. For brevity of the specification, details are not described herein.

[0039] The foregoing embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
