Description

Technical Field

[0001] The utility model relates to the technical field of shear head torque bolts, in particular to a novel puncture wire clamp plastic shear head torque bolt. Background Art

[0002] In overhead lines with rated voltage of 1kV and below, it is often necessary to butt or branch the conductors. After the joint pipe and parallel groove wire clamp are connected, insulation protection measures are added on the surface, that is, the insulation is first destroyed and then repaired. With the acceleration of urbanization, there is an urgent need to improve insulation performance and construction efficiency. Piercing wire clamps, as a new type of power connection hardware, are suitable for parallel groove connection or branch connection of 1kV and below low-voltage overhead bundled cables, and are widely used in various building power distribution systems and street lighting systems.

[0003] Deficiencies of existing technology:

[0004] As an important component of the piercing wire clamp, the torque bolt plays a vital role in the performance of the piercing wire clamp. The torque bolt currently used in the piercing wire clamp is usually made by riveting a bolt and a torque cap made of aluminum alloy. The torque cap controls the appropriate torque by cutting grooves, and the joint surface is not sufficient. However, the traditional aluminum alloy shear head torque bolt has high cost and low production efficiency. Utility Model Content

[0005] The utility model aims to provide a novel puncture wire clamp plastic shear head torque bolt to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of puncture wire clamp plastic shear head torque bolt, including a bolt, the bolt is provided with a connecting assembly, and the connecting assembly includes:

[0007] A plastic torque cap, wherein the plastic torque cap is connected to the bolt as a whole;

[0008] A groove is arranged on the top of the bolt, and the top of the bolt forms a hexagonal head with the groove.

[0009] Preferably, a shear groove is provided above the plastic torque cap.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The novel puncture wire clamp plastic shear head torque bolt is provided with a connection component. The connection component includes a plastic torque cap and a groove. The groove is formed at the top of the bolt, and the top of the bolt forms a hexagonal head with a groove, which increases the bonding surface with the plastic torque cap and also increases the dropout torque of the bolt, better adapting to various different installation torque requirements. Moreover, compared with the synthesis method of an aluminum alloy torque cap and a bolt, the plastic torque cap and the bolt with a groove on the hexagonal head are integrally formed by an injection molding process, with lower costs and higher production efficiency.
