The wire clamp seat 1 is fixedly connected with the main wire fixing component and the main wire, so that the existing condition that the branch wire is directly wound on the main wire is changed, the conditions that the contact pressure degree is not uniform and the contact is poor when the branch wire is directly wound on the main wire are avoided, and the wire clamp is tightly, stably and safely contacted with the main wire; a plurality of branches can be shunted to a fastener and come out, the condition that the insulating layer is peeled off to the thread multi-time multi-position in the prior art is avoided, the number of peeled openings is reduced, the damage to the thread caused by peeling of the insulating layer is reduced, meanwhile, the design is reasonable, the branches are distributed orderly, and the operation of workers is more convenient.
The upper fixing groove 22 and the lower fixing groove 21 are combined to form a complete fixing channel, the top of the upper fixing groove 22 is rotatably connected with the lower part of the main line fixing bolt 23, as shown in fig. 2, a convex disc 231 is arranged at the bottom of the main line fixing bolt 23, a groove 221 matched with the convex disc 231 is arranged at the top end of the upper fixing groove 22, so that the convex disc 231 can rotate in the groove 221 and cannot escape, and other rotating connection modes such as a rotating disc can be adopted between the main line fixing bolt 23 and the upper fixing groove 22. That is, the upper fixing groove 22 can be moved up and down on the wire holder 1 by the rotation of the main wire fixing bolt 23, and the upper fixing groove 22 does not rotate with the main wire fixing bolt 23. Firstly, rotating the main line fixing bolt 23 to lift the upper fixing groove 22, then placing the main line with the stripped insulating layer between the upper fixing groove 22 and the lower fixing groove 21, and then reversely rotating the main line fixing bolt 23 to lower the upper fixing groove 22 to be matched with the lower fixing groove 21 to fix the main line stably; then, one end of the branch is stripped of the insulating skin and inserted into the branch jack 3, and the branch fixing bolt 4 is screwed down to fix the branch.
The wire clamp seat 1 and the main wire fixing component are both made of conductive metal, the main wire fixing component is directly contacted with the main wire with the insulating layer stripped, and current flows to the main wire fixing component from the main wire, then flows to the wire clamp seat 1 and finally flows out from the branch wire inserted into the branch wire jack 3. The wire clamp seat 1 is a C-shaped wire clamp seat 1, the lower fixing groove 21 is located at the bottom in the C-shaped wire clamp seat 1 and fixedly connected with the C-shaped wire clamp seat 1, the upper fixing groove 22 is located at the upper portion in the C-shaped wire clamp seat 1, and the main wire fixing bolt 23 penetrates through the upper end of the C-shaped wire clamp seat 1 and is rotatably connected with the top of the upper fixing groove 22.
Example two: as shown in fig. 3-5, on the basis of the first embodiment, two ends of the wire clamp seat 1 are connected with the support rods 5, and the end of each support rod 5 is provided with the main wire support clamp 6.
Because the lengths of the wire clamp seat 1 and the main wire fixing component are not too long, after the main wire is fixed in the wire clamp, the main wire and the branch wire shake due to wind power and the like, so that shearing force is easily formed between the main wire and the wire clamp, and the end part of the main wire is damaged or broken, the supporting rods 5 are additionally arranged at the two ends of the wire clamp seat 1, and then the end parts of the supporting rods 5 are provided with the main wire supporting frames, which is equivalent to reinforcing the two ends of the wire clamp, so that the length of the wire clamp is prolonged, the shaking amplitude of the wire clamp and the main wire is reduced, and the shearing force between the wire clamp and the main wire is dispersed, so that the risks of breaking and damage of.
Example three: as shown in fig. 6, on the basis of the second embodiment, the upper portion and the lower portion of one side of the wire holder 1 are both provided with the branch jack 3, one side of the branch jack 3 is correspondingly provided with the branch fixing bolt 4, and an electric wire inlet 8 is formed between the upper portion and the lower portion of the wire holder 1. The cable clamp seat C type wire clamp seat, the side of C type wire clamp seat upper and lower part all sets up branch line jack 3, and the opening part is electric wire import 8 in the middle of the C type wire clamp seat, and the electric wire directly enters into the inside of wire clamp seat 1 from the electric wire import, then puts into between last fixed slot 22 and lower fixed slot 21 can.
Example four: as shown in fig. 7-8, on the basis of the first, second or third embodiments, the device further includes a branch line connector protection component inserted into the branch line jack 3, the branch line connector protection component includes a branch line slot 71, a branch line folding protection end 72 is further disposed at the top end of the branch line slot 71, and a positioning protrusion 73 adapted to the branch line folding protection end 72 is disposed on the branch line slot 71 and the branch line folding protection end 72.
The branch line insertion groove 71 is further provided with a plurality of branch line protection rings 74 or directly used as a protection through groove, and the branch lines can be directly inserted. The branch folding protection end 72 is made of flexible materials, so that the branch breaking protection end can be conveniently folded. The branch slot 71 and the branch folding protection end 72 are integrally formed. The branch line joint protection component can be made of flexible insulating materials or aluminum sheet supports, when the insulating materials are adopted, the branch line joint protection component can not completely wrap the end part of the branch line, and the end part of the branch line is required to be in direct conductive contact with the wire clamp seat 1 or the branch line fixing bolt 4.
The branch line is directly inserted into the branch line jack 3, the branch line is fixedly connected with the wire clamp seat 1 through the branch line fixing bolt 4, the main line and the branch line shake due to wind power and the like, the end part of the branch line on the wire clamp seat 1 is easy to form shearing force, the end part of the branch line on the wire clamp seat 1 is easy to damage or break, and the technical problem can be solved through the branch line joint protection assembly.
