Technical Field
[0001] The utility model relates to the technical field of cable or wire installation, and particularly relates to a wire clamp with both wire splitting and grounding functions. Background Art
[0002] The wire clamp for the distribution network is a key metal accessory in the power system for fixing, connecting and protecting wires. The wire clamp with the wire splitting function plays an important role in distributing electric energy in the power grid. The wire splitting mechanism ensures the connectivity stability. It is necessary to avoid over-tightening the main wire and damaging the insulation layer, and at the same time prevent the branch wire from becoming loose and falling off. Therefore, a stable and reliable wire splitting mechanism is particularly important.

[0030] Embodiment 1
[0031] See Figure 1 , a wire clamp with both wire splitting and grounding functions, including a base 100, a first wire clamping port 210, a second wire clamping port 220, a screw rod 300 and a grounding ring 400. The first wire clamping port 210, the second wire clamping port 220, the screw rod 300 and the grounding ring 400 are respectively installed on the base 100; both the first wire clamping port 210 and the second wire clamping port 220 are located on the same side of the base 100;
[0032] The first wire clamping port 210 includes a first fixing part 211 and a first clamping plate 212;
[0033] See Figure 5 , the second wire clamping port 220 includes a second fixing part 221, a moving plate 222, at least one spring 224 and a second clamping plate 223. At least one spring 224 is arranged between the moving plate 222 and the second clamping plate 223, and the second clamping plate 223 is close to the second fixing part 221;
[0034] When the screw 300 rotates in the first direction B: The first clamping plate 212 and the moving plate 222 move simultaneously. The first clamping plate 212 approaches the first fixing part 211 so that the first wire clamping opening 210 is clamped, and the moving plate 222 approaches the second fixing part 221 so that the second wire clamping opening 220 is clamped. When the first wire clamping opening 210 is clamped, a first wire clamping space 213 is formed between the first fixing part 211, the first clamping plate 212 and the base 100. When the second wire clamping opening 220 is clamped, a second wire clamping space 225 is formed between the second clamping plate 223, the second fixing part 221 and the base 100.
[0035] When the screw 300 rotates in the second direction C: The first clamping plate 212 moves away from the first fixing part 211 so that the first wire clamping opening 210 is opened, and the moving plate 222 moves away from the second fixing part 221 so that the second wire clamping opening 220 is opened. The first direction B is opposite to the second direction C. When both the first wire clamping opening 210 and the second wire clamping opening 220 are opened, the first distance is greater than the second distance. The first distance is the distance between the first clamping plate 212 and the first fixing part 211, and the second distance is the distance between the second clamping plate 223 and the second fixing part 221. The main wire and the branch wire have different thicknesses, that is, the radial dimension of the main wire is greater than the radial dimension of the branch wire. The appropriate first distance and second distance are designed respectively according to actual needs.
[0036] When the screw 300 rotates in the first direction B, the first wire clamping opening 210 forms the first wire clamping space 213 at the first time. The first wire clamping space 213 is a wire clamping space for ensuring the clamping of the main wire without operating the insulating layer. The second wire clamping opening 220 forms the second wire clamping space 225 at the second time. The second wire clamping space 225 is a wire clamping space for ensuring the clamping of the branch wire to the use state. The first time is not earlier than the second time. And when the second time is earlier than the first time, from the second time to the first time, the clamping state of the second wire clamping space 225 is maintained. During use, at the second time, the second wire clamping space 225 is formed between the second clamping plate 223, the second fixing part 221 and the base 100. Between the second time and the first time, the moving plate 222 continues to approach the second fixing part 221, at least one spring 224 deforms, and the second clamping plate 223 and the second fixing part 221 no longer approach each other, and the second wire clamping space 225 is maintained.
[0037] During operation, the clamping or opening of the first wire clamping port 210 and the second wire clamping port 220 can be achieved only by rotating the screw 300 along the first direction B or the second direction C. The operation is simple, the installation is convenient, and by presetting the first distance and the second distance, when the screw 300 rotates along the first direction B, the time when the first wire clamping port 210 of the wire clamping port 200 as the main line forms the first wire clamping space 213, that is, the first time, is not earlier than the time when the second wire clamping port 220 of the wire clamping port 200 as the branch line forms the second wire clamping space 225, that is, the second time. And when the second time is earlier than the first time, from the second time to the first time, the clamping state of the second wire clamping space 225 is maintained, which can avoid over-tightening of the main line and damaging the insulating layer during the clamping state, and at the same time prevent the branch line from becoming too loose and falling off, and the use process is stable and reliable. At the same time, when the screw 300 is rotated along the first direction B or the second direction C, only one side of the first wire clamping port 210 and the second wire clamping port 220 moves. One side of the first wire clamping port 210 is fixed, and the other side, that is, the first clamping plate 212, moves. One side of the second wire clamping port 220 is fixed, and the other side, that is, the moving plate 222 drives the second clamping plate 223 to move, which can reduce the operation difficulty during the clamping process and facilitate the operation.
[0038] Similarly, contrary to the clamping process, when the screw 300 is rotated along the second direction C, the first clamping plate 212 moves away from the first fixing portion 211 at the third time, and the second clamping plate 223 moves away from the second fixing portion 221 at the fourth time. The third time is not later than the fourth time, and when the fourth time is later than the third time, from the third time to the fourth time, the clamping state of the second wire clamping space 225 is maintained. At this time, a relative movement occurs between the second clamping plate 223 and the moving plate 222.
[0039] See Figure 1 、 4 , preferably, the axis of the first wire clamping space 213 is parallel to the axis of the second wire clamping space 225 to ensure the wire splitting and power distribution function of the wire clamp.
[0040] See Figure 5, in some embodiments, the screw 300 includes a rod body 310, a first thread portion 320, a second thread portion 330, and a force application portion 340; the rod body 310 is rotatably engaged with the base 100, and the force application portion 340 is disposed at one end of the rod body 310; the first thread portion 320 and the second thread portion 330 are respectively disposed on the circumferential side surface of the rod body 310, the first thread portion 320 is used to control the first clamping plate 212 to approach or move away from the first fixing portion 211, and the second thread portion 330 is used to control the moving plate 222 to approach or move away from the second fixing portion 221. The structure is simple. By rotating the screw 300 in the first direction B or the second direction C through the force application portion 340, the first direction B is clockwise or counterclockwise rotation with the axis direction of the rod body 310 as the axis, and the first direction B is opposite to the second direction C. Since the rod body 310 and the base 100 are rotatably engaged, during use, regardless of the clamping or opening process, that is, regardless of whether the screw 300 rotates in the first direction B or the second direction C, the screw 300 and the base 100 do not displace in the direction of the axis of the rod body 310, avoiding unnecessary accidental contact caused by the displacement of the screw 300 in the direction of the axis of the rod body 310 during the operation, and ensuring the operation safety.
[0041] In some embodiments, the base 100 includes a substrate 110 and a mounting box 120. The mounting box 120 is fixed to one side of the substrate 110, and both the first wire clamping port 210 and the second wire clamping port 220 are located on the other side of the substrate 110; when the screw 300 rotates in the first direction B or the second direction C, the first clamping plate 212 and the moving plate 222 respectively move back and forth on the corresponding side surfaces of the substrate 110;
[0042] An inner cavity 121 is formed in the mounting box 120. The rod body 310 penetrates through the inner cavity 121, and the rod body 310 is rotatably engaged with the mounting box 120. At least a part of the first thread portion 320 and at least a part of the second thread portion 330 are located in the inner cavity 121; the force application portion 340 is located outside the mounting box 120.
[0043] In some of these embodiments, a chute 111 is formed in the middle of the substrate 110. The axial direction of the screw 300 is parallel to the longitudinal direction of the chute 111, the moving direction of the first clamping plate 212, and the moving direction of the moving plate 222 respectively. A first threaded block 214 and a second threaded block 226 are respectively arranged in the inner cavity 121. The first threaded block 214 is in threaded cooperation with the first threaded portion 320, the first threaded block 214 is fixedly connected to the first clamping plate 212, the second threaded block 226 is fixedly connected to the moving plate 222, and the second threaded block 226 is in threaded cooperation with the second threaded portion 330. The connection between the first threaded block 214 and the first clamping plate 212 is in sliding cooperation with the chute 111, and the connection between the second threaded block 226 and the moving plate 222 is in sliding cooperation with the chute 111. When the screw 300 rotates in the first direction B or the second direction C, the first threaded block 214 drives the first clamping plate 212, and the second threaded block 226 drives the moving plate 222 to move along the axial direction of the rod body 310. The structure is simple and the operation is convenient.
[0044] In the prior art, the grounding ring 400 and the wire clamping space of the wire dividing clamp are usually installed on the same side of the base 100. During installation or maintenance, interference between the grounding ring 400 and the clamped wire (main wire or branch wire) often occurs, making the operation inconvenient.
[0045] To solve this problem, refer to Figure 3 , in some of these embodiments, the grounding ring 400 is installed on the side of the mounting box 120 away from the substrate 110.
[0046] The base 100 further includes a rear cover plate 130. The rear cover plate 130 is installed on the side of the mounting box 120 away from the substrate 110. A first arc groove is formed on the corresponding side of the mounting box 120, and a second arc groove is formed on the rear cover plate 130. When the rear cover plate 130 is installed on the mounting box 120, an installation hole is formed between the first arc groove and the second arc groove. The grounding ring 400 is installed in the installation hole. During installation, first place the installation part of the grounding ring 400 in the first arc groove, then make the second arc groove opposite to the first arc groove to form the installation hole, so that the installation part of the grounding ring 400 is limited in the installation hole. Finally, fix the rear cover plate 130 to the mounting box 120 with bolts 140 etc. The structure is simple and the installation is convenient. Moreover, the grounding ring 400 and the wire clamping space are located on opposite sides of the substrate 110, facilitating installation and maintenance.
[0047] Refer to Figures 1-5, in some of these embodiments, during use, the force - applying portion 340 of the thread is located below, the first wire - clamping opening 210 is above the second wire - clamping opening 220, the first fixing portion 211 is above the first clamping plate 212, and the second fixing portion 221 is below the second clamping plate 223. At this time, the thread directions of the first thread portion 320 and the second thread portion 330 are opposite. When the screw 300 rotates in the first direction B or the second direction C, the moving directions of the first clamping plate 212 and the moving plate 222 are opposite, which is especially suitable for the situation where the main line and the branch line need to be separated by a relatively long distance.
[0048] Embodiment 2
[0049] See Figure 6 , based on Embodiment 1, during use, the second fixing portion 221 is above the second clamping plate 223. At this time, the thread directions of the first thread portion 320 and the second thread portion 330 are the same. When the screw 300 rotates in the first direction B or the second direction C, the moving directions of the first clamping plate 212 and the moving plate 222 are the same. The fixing portion usually extends outwards to facilitate rain and dust protection, thereby increasing the service life of the wire clamp and ensuring safety. When the first fixing portion 211 is above the first clamping plate 212 and the second fixing portion 221 is above the second clamping plate 223, when the first wire - clamping opening 210 forms the first wire - clamping space 213, the upper part of the first clamping plate 212 is blocked by the first fixing portion 211, and when the second wire - clamping opening 220 forms the second wire - clamping space 225, the upper part of the second clamping plate 223 is blocked by the second fixing portion 221, achieving comprehensive rain and dust protection.
[0050] Embodiment 3
[0051] See Figure 7 , based on Embodiment 1, during use, the first wire - clamping opening 210 is below the second wire - clamping opening 220, which is suitable for the application scenario where the main line is below the branch line.
[0052] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than limiting the protection scope of the present invention. Any simple modification or equivalent replacement made by those of ordinary skill in the art to the technical solution of the present invention does not depart from the essence and scope of the technical solution of the present invention.
