Detachable deep water sealed connector

Abstract

The invention relates to a detachable deep water sealed connector. The detachable deep water sealed connector comprises a socket, a plug and a tail part accessory matched with the plug; the interfacebetween the plug and the socket and between the plug and the tail part accessory is sealed by two O-shaped rubber sealing rings separately; the socket and underwater operational equipment adopt axialand radial O-shaped rubber sealing rings for realizing sealing; the socket is a glass sintered socket, and the socket shell and a contact part are sintered into an integrated body through composite glass so as to realize longitudinal sealing; the sealing between the tail part accessory and a cable adopts a filler sealing mode; the tail part accessory is also provided with a cable shielding structure; a shielding spring sheet is connected with the tail part accessory, so that the contact area is enlarged, the contact resistance and shielding resistance of a shielding layer are lowered effectively, and true 360-degree annular shielding is realized; and the detachable deep water sealed connector is detachable integrally, convenient to maintain, compact in structure, high in universality and durable, and has the performance index of hydrostatic pressure resistance of 4.5MPa.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a deep-water sealing plug and a deep-water sealing shielding tail accessory. Background technique [0002] In the field of marine underwater engineering and equipment technology, with the acceleration of human exploration and development of the ocean, the wide use of underwater electrical equipment and devices is used to connect underwater electrical and surface terminal equipment or important components of power supply - underwater Connectors are also gradually developed, and their requirements are increasing, gradually expanding from 1MPa hydrostatic pressure requirements to 5MPa, 10MPa, and even higher hydrostatic pressure requirements. [0003] At present, most deep-water sealed connectors, in order to improve the sealing reliability and reduce the sealing parts as much as possible, most of the plugs have an integrated structure, that is, the tail attachment is omitted to...

AI Technical Summary

Problems solved by technology

However, this brings difficulties to the cable shielding process. This is because at the junction of the plug or socket and the tail accessories, it is necessary to achieve reliable sealing and ensure that the cable shield and the connector are effectively lapped to prevent electromagnetic leakage. At the same time, the cable core After the wire is welded to the contact in the plug or socket, the cable and the plug or socket become a whole, and the tail attachment must be displaced relative to it during the connection and sealing process of the plug or socket, that is, the tail attachment is displaced relative to the cable, so if the shielding of the cable is It is not feasible to fix the layer to the tail attachment, such as fixing to the plug or socket will increase the structural size of the connector
