Underwater plugging and unplugging connector

Abstract

The invention relates to an underwater plugging and unplugging connector which comprises a contact element and an insulator, wherein the contact element is connected with a cable; the insulator is internally provided with a contact element installation hole for installing the contact element; the contact element is arranged in the contact element installation hole; an embedment glue body is embedded at the opening part at the rear end of the contact element installation hole; the embedment glue body comprises a front embedment glue body part and a rear embedment glue body part; the front embedment glue body part is arranged between the contact element and the contact element installation hole and is used for sealing, fixing and assembling the contact element and the hole wall of the contact element installation hole; the rear embedment glue body part is arranged the outer periphery of the connecting part of the contact element and the cable and is used for enabling the connection part of the contact element and the cable to be insulated from outer part; the front embedment glue body part and the rear embedment glue body part are integrated; a vulcanization sleeve which is molded in an integrated vulcanization mode and plays a role of connection is wrapped on the periphery of the insulator and the periphery of the cable. The invention provides the underwater plugging and unplugging connector which can lower the matching property requirement of an electric cable material and a vulcanization material.

Description

technical field [0001] The invention relates to the field of underwater connectors, in particular to an underwater plug-in connector. Background technique [0002] The existing underwater plug-in connectors are all formed by one-time vulcanization, that is, the outer circumference of the cable and the contact piece is directly wrapped by vulcanized material. This one-time vulcanization molding not only has strict requirements on the sealing dimensions of the contacts of the adapter connector, but also has high requirements on the compatibility between the cable material and the vulcanized material. Because the vulcanized material should act as a seal for the contact to prevent water from flowing into the cable and equipment from the gap between the contact and the vulcanized material; Insulation; at the same time, the vulcanized material also acts as a tensile force between the contact and the cable. However, depending on the temperature resistance level of the cable, the ...

Problems solved by technology

However, depending on the temperature resistance level of the cable, the vulcanization temperature, the adhesiveness of the cable material and the vulcanized material, the vulcanization effect of the product is different. Commonly used cable materials generally require low-temperature vulcanization, but the insulation and flow properties of low-temperature vulcanized materials are poor, resulting in The insulation effect of the contact piece and the connection position between the contact piece and the cable is not good, which also leads to poor sealing effect between the contact piece and the vulcanized material, which ultimately leads to a low pass rate of the product
