AI Technical Summary

Technical Problem

In a high-voltage environment in deep water areas, underwater cable connectors are prone to cable movement inward, causing cracks in the contact position of the cable sheath and the compression structure, reducing the connection strength and tensile resistance.

Method used

A stop structure is provided in the housing of the underwater cable connector, which can be compatible with the cable sheath and insulator stops in the forward direction, thereby providing support and preventing the cable from moving inward.

Benefits of technology

With the support of the stop structure, the cable avoids moving into the shell in a deep water high-pressure environment, prevents the cable sheath from cracking, improves the connection strength and tensile resistance, and solves the problem of plastic-sealed colloid bulge.

Abstract

The present invention provides an underwater cable connector and a connector assembly, which belongs to the field of electrical connectors. The underwater cable connector includes a shell, the rear end of the shell is provided with a through-port for the end of the cable to pass into the shell from the back to the front, the through-port is provided with a clamping structure for clamping the cable, the inner side of the shell is provided with a stop structure, the rear end face of the stop structure is a stop surface for stopping and cooperating with the front end face of the cable insulator and / or the cable sheath in the forward direction, the stop structure is integrated with the shell, or the stop structure is composed of a stop body installed in the shell. The connector assembly includes a female connector and a male connector, at least one of the female connector and the male connector is an underwater cable connector. The present invention arranges a stop structure in the shell for supporting the cable, thereby avoiding the cracking of the cable sheath caused by the movement of the cable into the shell in a deep-water high-pressure environment and reducing the reliability of the connection between the plastic encapsulation colloid and the cable.
