Abstract

The invention pertains to the field of underwater connectors, and specifically discloses a watertight connector applied in underwater operations. The watertight connector is installed on an underwater device. The socket comprises a naval brass housing and a jack which is located in a first rubber vulcanized seal body. One end of the jack is connected with a wire, and the other end of the jack is provided with an independent inner cavity. An annular raised portion is included in the inner cavity. A second rubber vulcanized seal body of the plug is provided with pins. The bottom portion of each pin is provided with an independent rubber insulating rod. One end of each pin is connected with the wire in a cable, and the other end of each pin is inserted into the jack. The rubber insulating rod is inserted into the inner cavity and pressed against the annular raised portion. According to the invention, the socket and the corresponding plug can be inserted and extracted in the wet environment, can be used in shallow sea and deep sea, has the advantage of reliable sealing performance, is suitable for being used in various underwater operation devices, such as ROV, AUV, underwater self-propelled devices, etc., for transferring electrical signals, and can be used to solve the problem that existing underwater connectors cannot be subjected to wet insertion and extraction.

Description

technical field [0001] The invention belongs to the field of underwater connectors, in particular to a watertight connector used in underwater operations. Background technique [0002] With the application of underwater robots (ROVs) and underwater autonomous vehicles (AUVs) more and more widely, the requirements for the reliability of underwater connectors are getting higher and higher. The existing watertight connectors have the following problems: once moisture or water enters the joint seal between the socket and the plug, the insulation performance of the watertight connector will be degraded, affecting the insulation effect, and even leading to insulation failure. SUMMARY OF THE INVENTION [0003] In order to solve the problems of sealing failure and electrical insulation performance degradation caused by the phenomenon of water ingress and moisture ingress sometimes in the prior art, the purpose of the present invention is to provide an underwater device that can me...
