Metal shell watertight connector

Abstract

The invention provides a metal shell watertight connector. The metal shell watertight connector comprises a wire protecting sleeve assembly, a wire protecting barrel assembly, a female joint insertingassembly, a pin inserting assembly and a pin inserting reinforcing assembly, wherein the wire protecting barrel assembly is of a hollow barrel structure with a closed left end and an opened right end, and a mounting through hole is formed in the outer side wall of the hollow barrel structure; the wire protecting sleeve assembly is arranged in the mounting through hole; the right end of the wire protecting barrel assembly is connected with the female joint inserting assembly; the female joint inserting assembly is connected with the pin inserting component; and the pin inserting assembly is connected with the pin inserting reinforcing assembly. The metal shell watertight connector is reasonable in structure, convenient to install and connect, waterproof and reliable, and the underwater operation of the water depth of 0-6000 meters can be met; and in addition, the metal shell watertight connector is resistant to acid and alkali and corrosion, not aged easily, long in service life, capable of filling up the blank of a domestic deep water watertight connector, and has relatively high economic value and scientific research value.

Description

technical field [0001] The invention belongs to the field of underwater connectors, in particular to a metal shell watertight connector. Background technique [0002] With the increasing application of underwater robots (ROV) and underwater self-propelled vehicles (AUV), the requirements for the reliability of underwater connectors are getting higher and higher. The existing watertight connectors have the following problems: the connection between the socket and the plug is not firm, and the plug is easy to fall off from the socket during the underwater operation, resulting in the stop of the underwater operation, which not only affects the work efficiency, but also causes unnecessary economic losses Most of the prior art adopts plastic encapsulation process or the metal body is made of encapsulating protective wire, which has a high scrap rate, poor reliability, high damage, and easy aging, resulting in short service life and high relative cost.
