High voltage electric power piercing connector

Abstract

The invention discloses a high voltage electric power piercing connector. The high voltage electric power piercing connector comprises an upper line voltage cover and a lower line voltage cover, wherein a gear is arranged at a middle portion between the upper line voltage cover and the lower line voltage cover, the gear is transversely provided with a fixing bolt, a left side of the gear is engaged with a lower tooth bar, a right side of the gear is engaged with an upper tooth bar, the upper line voltage cover corresponding to the lower tooth bar is provided with a tooth bar limit groove, the lower line voltage cover corresponding to the upper tooth bar is further provided with a tooth bar limit groove, a left side of a lower portion of the lower tooth bar is fixedly provided with a lower engagement cover, a right side of an upper portion of the upper tooth bar is provided with an upper engagement cover, the upper engagement cover and the lower engagement cover are respectively provided with an arc-shaped insulation sheath, and the insulation sheaths are provided with piercing blades. Compared with a mode of utilizing a traditional bolt assembly to clamp an electric power cable, the high voltage electric power piercing connector realizes clamping of the electric power cable through mutual engagement of the gear and the tooth bars, the excellent anti-loosing effect is realized, and long-term stable reliable operation is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of power fittings for overhead lines, in particular to a high-voltage power puncture clamp. Background technique [0002] In the construction of overhead power lines, when the cable needs to be branched or spliced, it is necessary to connect two insulated wires together with a splicing clamp. The connection clamp, especially the piercing type connection clamp, has the characteristics of easy installation, low cost, safety, reliability and maintenance-free. Cable branches can be made without cutting off the main cable or stripping the insulation layer of the cable. The joints are completely insulated and can be used for live work, and can be branched at any position on the cable; no terminal box or junction box is needed; and the joints are resistant to twisting, Shockproof, waterproof, anti-corrosion and aging; the comprehensive benefits are obvious, and the cost performance is better than the traditional c...
