TECHNICAL FIELD

[0001] The present disclosure generally relates to power supply shielding techniques in communication devices, and more particularly to a power supply connector.

BACKGROUND

[0002] A radio remote unit (RRU) is a very critical device in a user base station. The RRU is mainly responsible for processing, transmission and reception of radio frequency (RF) signals. Usually, a power supply cable for supplying power to a RRU device has a shielding layer. During a process of supplying power to the RRU device, the shielding layer of the power supply cable is connected to a structural member of the RRU device and thus is connected to the ground via the RRU device to perform current discharging, thereby protecting the RRU device from a transient surge current caused by, for example, thunder and lightning.

[0003] With continuous miniaturization of the RRU device, a small-sized and low-cost power supply connector may be desired in order to supply power to the RRU device and perform the shielding and current discharging functions for the RRU device.

[0007] According to an embodiment, the metallic sheet and the metallic elastic sheet at a same side of the power supply connector may be integrated as a whole.

[0008] According to an embodiment, the metallic elastic sheets, each having a bow shape structure which is convex in middle, may be arranged at either side of the power supply connector plug respectively, and are connected to the metallic screw via the metallic sheets respectively.

[0009] According to an embodiment, the power supply connector plug may further include: a power supply wire placement and connection zone in which the power supply wire is placed and connected to the power supply connector plug.

[0010] According to an embodiment, the structural member may be made of metal.

[0011] According to an embodiment, an interference connection may be established between the metallic elastic sheets and the structural member after power supply connector plug is fitted into the power supply connector socket.

DETAILED DESCRIPTION

[0014] According to an embodiment of the present disclosure, a power supply connector includes a power supply cable, a power supply connector plug, a power supply connector socket and a structural member. The power supply cable includes, at one end of the power supply cable connected to the power supply connector plug, a power supply cable shielding wire formed of a shielding layer of the power supply cable and a power supply wire separated from the shielding layer. The power supply connector plug includes a shielding wire placement zone in which the power supply cable shielding wire is placed, a metallic screw for fixing the power supply cable shielding wire, two metallic elastic sheets connected to the structural member, and two metallic sheets connected to the two metallic elastic sheets respectively. The two metallic sheets are arranged at either side of the power supply connector plug respectively, and the two metallic elastic sheets are also arranged at either side of the power supply connector plug respectively. The metallic screw is arranged at one side of the power supply connector plug and is connected to the power supply cable shielding wire in the shielding wire placement zone and one of the metallic sheets. Another one of the metallic sheets is extended to an inner wall of the shielding wire placement zone, and is connected to the power supply cable shielding wire after the metallic screw is tightened.

[0015] The structure of the power supply connector according to the disclosure will be further described in conjunction with the appended drawings and embodiments. Fig. 1 shows the structure of the power supply connector according to an embodiment of the disclosure. The power supply connector includes a power supply cable 11, a power supply connector plug 12, a power supply connector socket 13 and a structural member 14.

[0016] The power supply cable 11 includes, at one end of the power supply cable connected to the power supply connector plug 12, a power supply cable shielding wire 111 formed of a shielding layer of the power supply cable and a power supply wire 112 separated from the shielding layer.

[0017] The power supply connector plug 12 includes: a shielding wire placement zone (not shown in Fig. 1) in which the power supply cable shielding wire is placed, a metallic screw 122 for fixing the power supply cable shielding wire 111, two metallic elastic sheets 123 connected to the structural member 14, and two metallic sheets 124 connected to the two metallic elastic sheets 123 respectively. The two metallic sheets 123 are arranged at either side of the power supply connector plug respectively, and the two metallic elastic sheets 124 are also arranged at either side of the power supply connector plug respectively. The metallic screw 122, at one side of the power supply connector plug, is connected to the metallic elastic sheet 123 via the metallic sheet 124.

[0018] A shielding wire placement zone 121 is arranged at another side of the power supply connector plug as seen from Fig. 2, and thus the shielding wire placement zone 121 cannot be seen from Fig. 1. Fig. 2 is schematic structural diagram of the power supply connector plug 12 after being flipped over according to the embodiment of the disclosure. As shown in Fig. 2, the power supply connector plug 12 includes: a shielding wire placement zone 121 in which the power supply cable shielding wire is placed, a metallic screw 122 for fixing the power supply cable shielding wire 111, two metallic elastic sheets 123 connected to the structural member 14, and two metallic sheets 124 connected to the two metallic elastic sheets respectively. The two metallic sheets 124 are arranged at either side of the power supply connector plug 12 respectively, and the two metallic elastic sheets 123 are also arranged at either side of the power supply connector plug 12 respectively.

[0019] As shown in Fig. 1 and Fig. 2, the metallic screw 122 is arranged at one side of the power supply connector plug 12 and is connected to the power supply cable shielding wire 111 in the shielding wire placement zone and one of the metallic sheets 124. Another one of the metallic sheets 124 is extended to an inner wall of the shielding wire placement zone 121, and is connected to the power supply cable shielding wire 111 after the metallic screw 122 is tightened. The metallic sheet 124 and the metallic elastic sheet 123 at a same side of the power supply connector may be integrated as a whole.

[0020] The way in which the metallic sheets 124 is extended to the inner wall of the shielding wire placement zone 121 may be determined depending on specific design requirements of the power supply connector plug.

[0021] During a process of designing the power supply connector, the metallic sheet 124 and the metallic elastic sheet 123 may be formed by blending one and the same metallic plate. Taking a metallic plate connected to the metallic screw as an example, a portion of the metallic plate connected to the power supply connector socket is taken as the metallic sheet 124, and the remaining portion of the metallic plate is blended upward to form the metallic elastic sheet 123 having a bow shape structure which is convex in middle. A fixed connection (e.g., through welding, locking) may be established between the metallic sheet 124 and the metallic elastic sheet 123. The structure and connection of the metallic sheet 124 and the metallic elastic sheet 123 according to the disclosure shown in Fig. 1 is exemplary and the disclosure is not limited thereto.

[0022] The metallic elastic sheets 123, each having a bow shape structure which is convex in middle, are arranged at either side of the power supply connector plug 12 respectively, and are connected to the metallic screw 122 via the metallic sheets 124 respectively.

[0023] The power supply connector plug 12 may further include: a power supply wire placement and connection zone 125 in which the power supply wire 112 is placed and connected to the power supply connector plug 12.

[0024] According to an embodiment, the structural member 14 may be made of metal. An interference connection may be established between the metallic elastic sheets 123 and the structural member 14 after power supply connector plug 12 is fitted into the power supply connector socket 13. In this way, after power supply connector plug 12 is fitted into the power supply connector socket 13, the power supply cable shielding wire 111 may be directly connected to the structural member 14 via the metallic elastic sheets 123 of the power supply connector plug 12, so as to perform current discharging of the shielding layer of the power supply cable, without connecting the power supply cable shielding wire 111 to a housing of the power supply connector plug 12 and a housing of the power supply connector socket 13.

[0025] In the power supply connector plug 12 according to the disclosure, electrically conductive components such as the shielding wire placement zone 121, the metallic sheets 124, the metallic elastic sheets 123, the metallic screw 122 and the power supply wire placement and connection zone 125 may be made of metal. Other portions of the power supply connector plug 12 for supporting and fixing the electrically conductive components may be made of electrically insulating material such as plastic material. Therefore, less metal may be used and a small-sized and low-cost power supply connector may be obtained.

[0026] Fig. 3 is a schematic connection diagram of the power supply connector according to the embodiment of the disclosure. In Fig. 3, a power supply cable 31, a power supply connector plug 32, a power supply connector socket 33 and a structural member 34 are shown. In conjunction with the composition and connection shown in Fig. 3, Fig. 4 shows a method for connecting the power supply connector according to an embodiment of the disclosure. The method includes the following steps.

[0027] In Step 401, a shielding layer of the power supply cable 31 is separated from a power supply wire and is twisted to form a power supply cable shielding wire 35, at one end of the power supply cable 31 connected to the power supply connector plug 32.

[0028] In Step 402, the power supply cable shielding wire 35 is placed within a shielding wire placement zone 36 of the power supply connector plug 32.

[0029] In Step 403, a metallic screw 37 in the power supply connector plug 32 for fixing the power supply cable shielding wire 35 is tightened.

[0030] The tightened metallic screw 37 is connected to the power supply cable shielding wire 35 on one hand, and is connected to a metallic sheet 38 at one side of the power supply connector plug 32 on the other hand, so as to be connected to a metallic elastic sheet 39 via the metallic sheet 38.

[0031] After the metallic screw 37 is tightened, the power supply cable shielding wire 35 closely clings to an inner wall of the shielding wire placement zone 36 with fastening of the metallic screw 37. During the processing of designing the power supply connector, a metallic sheet 38 at another side of the power supply connector plug 32 is extended to the inner wall of the shielding wire placement zone, and is connected to the power supply cable shielding wire 35 after the metallic screw 37 is tightened.

[0032] The metallic sheet and the metallic elastic sheet at a same side of the power supply connector are integrated as a whole, so as to connect the power supply cable shielding wire 35 to the metallic elastic sheets 39.

[0033] Here, in order to guarantee normal electrical conduction of the power supply cable, the power supply wire separated from the shielding layer is connected to the power supply connector plug 32 after the power supply cable shielding wire 35 is connected and fixed. Specifically, the power supply wire is placed in the power supply wire placement and connection zone of the power supply connector plug 32, and is fixed and connected.

[0034] In Step 404, the power supply connector plug 32 is inserted into the power supply connector socket 33.

[0035] After the power supply connector plug 32 is inserted into the power supply connector socket 33, an interference connection is established between the metallic elastic sheets 39 and the structural member 34.

[0036] Meanwhile, the power supply wire is connected, via the power supply connector plug 32 and the power supply connector socket 33, to a device which is to be supplied with power.

[0037] The power supply connector according to the embodiment of the disclosure is merely exemplary and the disclosure is not limited thereto. The skilled in the art should understand that, modifications, equivalent replacements of some or all of the technical features, or exchanges between positions of some components can be made to the technical solutions of the embodiments, without departing from the essence of the technical solutions of the embodiments of the disclosure.

[0038] The above-mentioned embodiments are merely preferred embodiments and are not intended to limit the protection scope of the disclosure.
