High-reliability AC contactor wiring assembly for tightener

The utility model provides a high reliability AC contactor wiring assembly of tightener, including wire holder and connecting mechanism, and wire holder and wire pass through connecting mechanism connection, compared with the prior art, the connecting mechanism is composed of steering member, conductive sleeve, arc cover and elastic member, arc cover and wire holder are fixedly connected; the conductive sleeve is connected with the arc-shaped cover through an elastic piece. According to the utility model, the wire sleeve drives the steering member to move in the conductive sleeve, so that breakage of the end part of the wire due to long-term bending caused by movement of the connecting mechanism can be avoided, and when the wire is pulled by external force, the elastic member buffers the pulling force through the elasticity of the elastic member, thereby effectively preventing the wire from falling off from the connecting mechanism or preventing the wire from being pulled and broken; the wiring assembly has b
