Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of network engineering, in particular to a pre-twisted wire type tension clamp. Background Art
[0002] The pre-twisted wire tension clamp is a clamp specially designed for overhead lines. It is used to fix cables or wires. It is particularly suitable for the middle and terminal parts of the line. It applies pressure to the cable by pre-twisting the wire to achieve a stable tension and fixation effect. It has the characteristics of simple structure and easy operation.
[0003] When existing pre-twisted wire tension clamps are used to connect and install horizontal cables, the pre-twisted wires are mostly directly wrapped around the surface of the cables to connect and fix them. When affected by shaking, the ends of the pre-twisted wires will rub against the surface of the cables, causing the surface of the cables to be easily damaged. Over time, the cables may even break. When the cables are installed in the clamps, the clamps cannot provide protective clamping for them, causing the cables to be damaged in the clamps due to friction. In order to solve the above problems, while facilitating the installation of the cables, the ends of the pre-twisted wires can be prevented from damaging the cables, and the clamping of the cables can be improved to facilitate the installation and use of the cables. For this purpose, we propose a pre-twisted wire tension clamp. Utility Model Content
