A one-way pressurized plug and an electrical connector assembly using the same

Abstract

The invention relates to a field of an electrical connector, particularly to a one-way pressurized plug and an electrical connector assembly using the same. The one-way pressurized plug configures the front end thereof as a plug end, and comprises a pressurized insulator and contacts provided on the pressurized insulator, wherein the pressurized insulator is provided with a pressure-relief channel which extends through the pressurized insulator from front to back, a valve spool is provided in the pressure-relief channel, and the valve spool and the pressure-relief channel together constitute a one-way valve structure which only can be turned on from front to back. In the process of using the one-way pressurized plug, when the peripheral surface of the plug forms a seal fit with the inner wall surface of a closed conduit and the plug needs to be drawn close to a matched socket to realize an insertion, as the plug is getting closer and closer to the socket, an increscent pressure or a knock-out member provided on the socket impels the valve spool to move so as to open the pressure-relief channel, thereby achieving a pressure relief between the insertion interfaces of the plug and the socket and then preventing a problem of the damage of the plug or the socket from occurring. Therefore, the inventive one-way pressurized plug can automatically release pressure when inserted in a closed conduit and is applicable to the closed conduit.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a one-way pressure-bearing plug and an electrical connector assembly using the plug. Background technique [0002] Pressure-bearing electrical connectors are a special type of electrical connectors, and they are mostly used in occasions that need to withstand gas or liquid pressure between the two ends, so there are stricter requirements on sealing performance and strength. [0003] For pressure-bearing electrical connectors, the insulating components used to assemble contacts are components that directly affect their pressure-bearing sealing performance. In the prior art, the insulating components used in pressure-bearing electrical connectors are mostly glass insulators or ceramic insulators, etc. . [0004] The use of the glass insulator and the ceramic insulator greatly improves the pressure-bearing sealing performance of the pressure-bearing electrical connector. Howev...

AI Technical Summary

Problems solved by technology

However, with the continuous expansion of the application field of electrical connectors, the pressure-bearing electrical connectors that can only bear pressure have gradually begun to fail to meet the demand.

For example, in some closed pipelines with pressure, the outer circumference of the plug and socket of the electrical connector assembly is required to be tightly fitted with the inner wall of the pipeline, and at the same time, the respective tails of the plug and socket are under pressure. One of the plug and the socket moves closer to the other. However, since the plug and the socket are each sealed with the inner wall of the pipeline, if the existing electrical connector with only a single sealing and pressure-bearing function is used, in the process of moving closer to each other, the The medium between the plug and the socket is continuously compressed, which will cause the pressure between the two parts to increase continuously, causing other functional parts in the connector to be crushed.

[0005] To sum up, there is currently no one-way pressure-bearing electrical connector on the market that can automatically release pressure when inserted into a closed pipeline
