Sealing cover for high-voltage cable connector

Abstract

The invention discloses a sealing cover for a high-voltage cable connector. The sealing cover for the high-voltage cable connector consists of an insulating shell. The top surface of the insulating shell is open; three blind holes are formed in the bottom surface of the insulating shell; a phase line static contactor rod is fixedly arranged at the bottom of any blind hole; the external diameter of the phase line static contactor rod is smaller than the internal diameter of the blind hole; the height of the phase line static contactor rod is smaller than the height of the blind hole; at least one protruding edge is arranged on the side wall of the inner cavity of the insulating shell and parallel to the axial direction of the insulating shell; and external threads are arranged at the upper end of the insulating shell. When moveable contactor rods enter the blind holes and then are connected with the static contactor rods, connecting parts of the moveable contactor rods are positioned inside the blind holes, and the inner wall of the upper end of the blind hole and the upper side surface at the bottom of the insulating shell are arranged between adjacent connecting parts at intervals, so that the surface distance is greatly increased and the creepage phenomenon is prevented; the protruding edge on the inner wall of the insulating shell can prevent fault connection of a phase line; the upper end of the insulating shell is connected with a sealing cap through threads, so that the insulating shell can be sealed; and when the high-voltage cable connector is used underground, the water-proof and insulating performance of the high-voltage cable connector can be still kept.

Description

technical field [0001] The invention relates to the electrical field, in particular to a cable connector, in particular to a high-voltage cable connector sealing cover. Background technique [0002] In the prior art, a cable connector is used to connect the cable and the transformer. The cable connector is composed of a shell, an insulating sleeve, a phase line moving contact rod and a phase line static contact rod. The phase line moving contact rod is arranged in the insulating sleeve, and the phase line static contact rod is fixedly arranged in the shell. However, the distance between the connection points of the three static contact rods and the moving contact rod is short, and when the cable connector is used to connect high voltage, the three static contact rods are likely to generate creepage through the inner wall of the housing, resulting in failure. If the distance between the three static contact rods is increased, the cable connector will be too bulky and cannot ...

AI Technical Summary

Problems solved by technology

However, the distance between the connection points of the three static contact rods and the moving contact rod is relatively short. When the cable connector is used to connect high voltage, the three static contact rods are prone to creepage through the inner wall of the housing, resulting in failure.

If the distance between the three static contact rods is increased, the cable connector will be too bulky and cannot be installed with the transformer
