Among them, the first clamp body 1, the second clamp body 2 and the limit assembly 3 are all made of insulating hard plastic material, such as polyethylene, polyvinyl chloride, etc., with good corrosion resistance, electrical insulation, hardness and high-frequency insulation, ensuring the personal safety of maintenance personnel. At the same time, the wire clamp is easy to process, light in weight and convenient to carry. The first clamp body 1 and the second clamp body 2 are both one-lift molding structures, and both have a clamping part and a handle part, which improves the connection strength between the first clamp body 1 and the second clamp body 2 and extends the service life.

[0027] In an optional embodiment, the clamping cavity 7 includes a first cavity 71 and a second cavity 72, the first cavity 71 is connected to the second cavity 72, and the first cavity 71 is arranged close to the opening 6; the clamping space cross section of the first cavity 71 is an elliptical structure, and the clamping space cross section of the second cavity 72 is a circular structure. Specifically, the second cavity plays a role in wrapping the wire end, and the wire is clamped by the clamping force in the first cavity 71, so that the wire is clamped.

[0028] In an optional embodiment, if Figure 5As shown, the cavity wall of the first cavity 71 is provided with a first anti-slip portion 711 to prevent the wire from shifting, and the cavity wall of the second cavity 72 is provided with an arc-shaped insulating layer 721. Specifically, the first anti-slip portion 711 is made of rubber material, and the first anti-slip portion 711 is provided on the cavity wall of the first cavity 71 by hot pressing or gluing. The first anti-slip portion 711 is provided with anti-slip convex points arranged in a matrix, which increases the contact area between the cavity wall of the first cavity 71 and the wire, making it difficult for the wire to shift, ensuring the stability of the clamping of the wire clamp, firmly clamping the wire, and preventing it from slipping during live operation. The arc-shaped insulating layer 721 covers the exposed part of the wire, and the material has excellent insulation performance to ensure reliable protection in various working environments, while reducing the risk of electric shock to operators.

[0029] In an optional embodiment, if Figure 1 and Figure 5 As shown, the limiting assembly 3 includes a limiting seat 31 and a screw rod 32. The limiting seat 31 is convexly arranged on the surface of the second clamp body 2 facing the first clamp body 1, and is provided with a thread groove 311. The thread groove 311 extends to the first clamp body 1, and the screw rod 32 is threadedly connected with the thread groove 311. Specifically, the limiting seat 31 is a truncated cone structure, and is integrally formed with the second clamp body 2, and has good stability. The screw rod 32 is screwed into the thread groove 311 from the surface of the second clamp body 2 away from the first clamp body 1, passes through the second clamp body 2 and the limiting seat 31 in sequence, and is exposed. At the same time, the length of the thread groove 311 is long, which increases the contact area between the thread groove 311 and the screw rod 32, and can effectively prevent the screw rod 32 from being skewed.

[0030] In an optional embodiment, if Figure 5As shown, a locking handle 33 is provided at one end of the screw rod 32, and a contact piece 34 is provided at the other end.

Specifically, the cross-sectional area of ​​the locking handle 33 is larger than that of the screw rod 32, which is convenient for the staff to grasp and rotate the screw. The contact piece 34 and the screw rod 32 are separately arranged to facilitate the installation of the screw rod 32. Furthermore, the installation process of the screw rod 32 is as follows: one end of the screw rod 32 is welded or threadedly connected with the locking handle 33, and the other end is threadedly penetrated through the second clamp body 2 and the limit seat 31.

The staff rotates the screw toward the first clamp body 1 through the locking handle 33. When the contact piece 34 abuts against the first clamp body 1, the position of the first clamp body 1 can be fixed, so that the first clamp body 1 cannot approach the second clamp body 2, thereby preventing the wire clamp from being accidentally opened, ensuring safety and reliability during operation.

Specifically, the insulating clamping end 4 is covered with the second anti-slip portion 41, which is made of plastic or rubber and has a good anti-slip effect. The second anti-slip portion 41 has a plurality of anti-slip particles distributed in a matrix, which can provide sufficient gripping force for maintenance personnel when clamping the exposed wire, effectively preventing slipping.

When the wire clamp clamps the wire, the first limiting convex edge 11 abuts against the edge of the second clamp body 2, and the second limiting convex edge 21 abuts against the edge of the first clamp body 1, further ensuring the clamping stability of the wire clamp and preventing the wire from shifting.

[0033] In an optional embodiment, if Figure 2As shown, a rubber pad 12 is provided on the surface of the handle portion of the first clamp body 1 facing the second clamp body 2, and the rubber pad 12 abuts against the end surface of the limit assembly 3. Specifically, the rubber pad 12 abuts against the contact member 34, so that the first clamp body 1 cannot approach the second clamp body 2, thereby preventing the wire clamp from being accidentally opened, ensuring safety and reliability during operation.

[0034] In an optional embodiment, if Figure 3 and Figure 4 As shown, it includes an axle pin 8 and a torsion spring 9, a first connection part 13 is provided in the middle of the first clamp body 1, and a second connection part 22 is correspondingly provided in the second clamp body 2, and the first connection part 13 and the second connection part 22 are movably connected through the axle pin 8 and the torsion spring 9.

[0035] When in use, the maintenance personnel presses the handle of the first clamp body 1 towards the second clamp body 2, so that the clamping part of the first clamp body 1 moves away from the second clamp body 2 and approaches the exposed wire end of the wire, adjusts the position of the wire end to be located in the clamping cavity 7, releases the handle of the first clamp body 1, and the clamping part of the first clamp body 1 automatically returns to the initial position through the torsion spring 9 and the shaft pin 8 to clamp the wire end, and then rotates the screw rod 32 through the locking handle 33 to move the screw rod 32 towards the first clamp body 1, and its end abuts against the first clamp body 1 to limit the movement of the first clamp body 1.
