Preferably, the binding post and the wiring terminal of the high-voltage switch cabinet are of an integrated structure or of a split structure which are fixedly connected together.
Preferably, the wiring terminal and the high-voltage switch cabinet wiring terminal are of a split structure which is fixedly connected together, the end part of the wiring terminal is provided with a protruding bolt connector, the high-voltage switch cabinet wiring terminal is provided with a screw hole, one end of the wiring terminal is in threaded fixed connection with the high-voltage switch cabinet wiring terminal through the bolt connector, and the end plane of the wiring terminal is clung to the end plane of the high-voltage switch cabinet wiring terminal.
Preferably, a nut structure is fixedly arranged on the binding post.
Preferably, the inner cavity of the lock nut is of a conical structure, so that the left side wall and the right side wall of the clamping groove can be continuously contracted inwards in the process of tightening the lock nut on the binding post.
Preferably, the insulating sheath is provided with an opening for installing the lock nut, and an end cover for opening or closing the opening is arranged at the opening.
The cable connector has the beneficial effects that the wiring terminal and the binding post are in surface contact by tightly holding the contact rod through the contact cavity, and the contact cavity and the contact rod are of cylindrical structures, so that the contact area is large, the overcurrent capacity is high, the situation of poor contact is not easy to occur, the problem of heating at the connecting part caused by poor contact between the wiring terminal and the wiring terminal of the high-voltage switch cabinet can be effectively avoided, the service life is long, the structure is simple, and the installation is convenient.
