Shielded connector for high voltage cable joint {SHIELD CONNECTOR FOR HIGH VOLTAGE CABLE JOINT}

The present invention relates to a shield connector, and more particularly, to a shield connector for a high-voltage cable joint, which can very simply and quickly perform a jointing operation between two or more cables.

Environmental vehicles such as hybrid vehicles and electric vehicles use high-voltage cables, and the high-voltage cables consist of a conductor (centre core), an insulating inner sheath surrounding the conductor, and a conductive material shield (shield) surrounding the inner sheath. ) and an outer shell of insulating material surrounding the shield. The shield of the high-voltage cable is configured to minimize interference of electromagnetic waves.

In order to joint two or more high-voltage cables, after connecting the conductors of the cables, the connected conductors are compressed, the shield film is compressed around the crimped portion of the conductors, the shield film is compressed, and a heat shrink tube is placed around the compressed shield film. By mounting , the joint work of two or more cables is performed.

As such, according to the prior art, the joint of the high voltage cables needs to be manually performed as additionally required for crimping of the shield for the continuity of the shielding, so a lot of time and a lot of equipment are required, which takes a long time to work. Not only did it take time, but the work process was complicated.

The present invention has been devised in consideration of the above points, and an object of the present invention is to provide a shielded connector for a high-voltage cable joint that can perform a joint operation between cables very simply and quickly while maintaining the shielding function of the high-voltage cable. there is.
