Description

Technical Field

[0001] The invention relates to the field of line clamping tools for power transmission lines, in particular to a distribution line clamp. Background Art

[0002] In the existing power transmission circuit, the main circuit is split into multiple branches, which requires the use of branching wire clamps. The branching wire clamps in the prior art generally include the following two types: fixed wire clamps and tension wire clamps. The function of using the wire clamps is to fix the main circuit, and then divide the main circuit through the splitter. That is, two sets of devices are usually used to fix and connect the main circuit and the branch. Its installation efficiency is low and the installation is complicated, and the operation risk is high.

[0003] The Chinese invention patent No. 2012201108611 discloses a V-shaped wire clamp, which includes a V-shaped element, a wedge, and a bolt; the V-shaped element has a V-shaped groove, and arc-shaped grooves are provided on the two inner sides of the upper opening of the V-shaped groove; the wedge is fixed in the V-shaped groove by bolts. The V-shaped wire clamp is easy to install and maintain the wire, and after installation, due to the large contact area, strong grip and good overload capacity, the line performance is stable, but it cannot achieve circuit power distribution. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a branch line clamp, which fixes the main line and the branch line at the same time, realizes the fixation of the line and can shunt the main line at the same time, and has firm fixation and high installation efficiency.

[0005] In order to solve the above technical problems, the present invention provides a branch wire clamp, including a wire clamp body that is conductive and made of elastic aluminum alloy, and its structural characteristics are: a sink groove facing the right side and recessed from the right to the inside is provided on the right side of the wire clamp body, and the cross-section of the sink groove is an arc shape. A push plate that can swing and is tilted upward from left to right is connected to the sink groove, and a main cable pressure block is connected to the right end of the push plate. The cross-section between the push plate and the main cable pressure block is spherical, and the main cable pressure block is tilted downward from left to right. The right end of the main cable pressure block and the wire clamp body are correspondingly provided with an arc-shaped clamping opening that can clamp the main cable, and a connecting bolt that can pass through the pushing plate and the main cable pressure block is connected to the wire clamp body, and a pressure head is connected to the top of the connecting bolt, and the distance between the two arc-shaped clamping openings can be reduced and expanded as the connecting bolt is screwed, and at least two cable passing holes for branch line draws to pass through are provided on the left side of the wire clamp body, and a clamping bolt that can extend into the cable passing hole and clamp the branch line draw is installed on the wire clamp body.

[0006] After adopting the above structure, the arc-shaped clamp can clamp the main cable, and at the same time, the two arc-shaped clamps are closed by screwing the connecting bolts, so as to firmly clamp the main cable. The branch cable can pass through the cable through hole, and the branch cable can be compressed by the clamping bolt, thereby ensuring the clamping and compression of the branch cable. From the above installation process, it can be seen that the present invention can clamp the main cable and the branch cable at the same time to form a tension clamp, thereby achieving firm clamping of the main cable and the branch cable, and at the same time achieving power distribution (i.e., shunting of the main cable), greatly improving the installation efficiency. In addition, the arc-shaped clamp of the above structure is set, which not only plays the role of firmly clamping the main cable, but also can achieve the clamping of main cables of various thicknesses according to the setting of the clamp distance. The application of the present invention is more extensive.

[0007] A notch is provided at the connection portion between the push plate and the main cable clamp for the connection bolt to pass through, and the diameter of the notch is larger than the diameter of the connection bolt. The wire clamp body is provided with a long hole extending from left to right, and the connection bolt is installed in the long hole.

[0008] The pressure head is a pressure nut threaded on the upper part of the connecting bolt, and the bottom of the connecting bolt is provided with a lower end head which can abut against the bottom surface of the wire clamp body.

[0009] The pressure head is an upper end head arranged on the upper part of the connecting bolt and capable of pressing against the push plate and the main cable pressure block. A bottom nut capable of pressing against the bottom surface of the wire clamp body is threadedly connected to the lower extension section of the connecting bolt after passing through the wire clamp body.

[0010] The cable passing holes are arranged transversely and are arranged in multiple rows and columns.

[0011] The row of cable passing holes located above is arranged opposite to or staggered with the row of cable passing holes located below.

[0012] The inner surface of the arc-shaped clamping opening is a concave smooth arc surface.

[0013] The inner surface of the arc-shaped clamping opening is an arc surface, and the arc surface is provided with strip teeth or densely covered with anti-slip protrusions.

[0014] In summary, the present invention can fix the main line and the branch line, and can shunt the main line while fixing the line, and has the advantages of firm fixation and high installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Reference Figures 1 to 4 As shown, the present invention provides an embodiment of a distribution wire clamp. For the convenience of description, Figure 1 The left and right directions in the present invention are the left and right directions. Figure 1 The up and down directions are the up and down directions of the present invention. The distribution wire clamp includes a conductive wire clamp body 1. The wire clamp body 1 is made of elastic aluminum alloy, which is an aluminum alloy with elasticity after heat treatment. The specific material structure of the aluminum alloy is the prior art and will not be repeated here. The process of heat treatment is also the prior art. The right side of the wire clamp body 1 is provided with a sink 11 facing the right side and recessed from the right to the inside. The cross section of the sink 11 is an arc shape. The sink 11 is connected to a push plate 8 that can swing and is tilted upward from left to right. The left end of the push plate 8 is a cylindrical end. The outer surface of the cylindrical end is an arc shape that is adapted to the sink 11. The cylindrical end can be inserted into the sink 11 to realize the swing of the push plate 8, that is, the above-mentioned cylindrical end forms a cylindrical match with the sink 11 (the cross section is as shown in FIG. Figure 1The arc surface fit shown in the figure), the push plate 8 swings around the center point of the above arc surface fit, the right end of the push plate 8 is connected to the main cable pressure block 2, the cross-section between the push plate 8 and the main cable pressure block 2 is spherical fit, the main cable pressure block 2 is tilted downward from left to right, the right end of the main cable pressure block 2 and the wire clamp body 1 are correspondingly provided with an arc-shaped clamping opening 3 that can clamp the main cable, the wire clamp body 1 is connected with a connecting bolt 4 that can pass through the push plate 8 and the main cable pressure block 2, the top of the connecting bolt 4 is connected with a pressure head 41 and the distance between the two arc-shaped clamping openings 3 can be reduced and expanded as the connecting bolt is screwed, the left side of the wire clamp body 1 is provided with at least two cable passing holes 5 for the branch line to pass through, and the wire clamp body 1 is equipped with a clamping bolt 6 that can extend into the cable passing hole 5 and clamp the branch line. In order to realize the swing of the push plate 8 and ensure that the distance of the arc-shaped clamping opening can be adjusted during the swing (so that the left end of the push plate 8 does not move), a notch is provided at the connection part of the push plate 8 and the main cable clamp 2 for the connection bolt 4 to pass through, and the diameter of the notch is larger than the diameter of the connection bolt 4. The wire clamp body is provided with a long hole extending from left to right, and the connection bolt 4 is installed in the long hole. The pressure head 41 is a top pressure nut screwed on the upper part of the connection bolt 4, and the bottom of the connection bolt 4 is provided with a lower end head 42 that can abut against the bottom surface of the wire clamp body 1.

[0023] As shown in the accompanying drawings, the right end of the main cable pressing block 2 and the wire clamp body 1 are correspondingly provided with an arc-shaped clamping opening 3 capable of clamping the main cable. The inner surface of the arc-shaped clamping opening 3 is an arc surface, and the arc surface is provided with strip teeth or densely covered with anti-slip protrusions, such as Figure 1 As shown in the figure, bar teeth are schematically shown, and an anti-slip protrusion structure can also be used. The anti-slip protrusion structure is not shown in the figure. Its purpose is to increase the friction force of cable clamping, thereby ensuring the firmness of clamping. Of course, the inner surface of the arc-shaped clamping mouth 3 of the present invention can also be a concave smooth arc surface.

[0024] As shown in the accompanying drawings, the left side of the wire clamp body 1 is provided with at least two cable through holes 5 for the branch lines to pass through. Figure 1 In the embodiment, four holes are arranged. The clamp body 1 is provided with a clamping bolt 6 which can be inserted into the cable through hole 5 and clamp the branch line. The cable through holes 5 are arranged horizontally and in multiple rows and columns. The upper row of cable through holes 5 is arranged opposite to or staggered with the lower row of cable through holes 5. Figure 1 The cable passing holes 5 of the embodiment are staggered, which can reduce the volume of the entire wire clamp to the greatest extent.

[0025] When the present invention is in use, the connecting bolt 4 is loosened, the connecting part of the push plate 8 and the main cable pressing block 2 is arched upward, so that the distance between the two arc-shaped clamps 3 becomes larger, and the main cable is put on, and then the connecting bolt 4 is tightened, the push plate 8 swings and the connecting part of the push plate 8 and the main cable pressing block 2 falls, so that the distance between the two arc-shaped clamps 3 becomes smaller, the main cable is firmly clamped, and then the branch cable is passed through the cable passing hole 5, and the branch cable is compressed by the compression bolt 6, thereby achieving the clamping and compression of the main cable and the branch cable and realizing circuit diversion.
