A gas circuit contact and an electrical connector with the gas circuit contact

Abstract

The invention provides a gas circuit contact piece, which includes a gas circuit pin and a gas circuit jack, both of which are provided with a through inner hole, and the inner hole of the gas circuit jack is provided with a valve body and a sealing body , Valve seat and return spring, wherein the valve body and the valve seat are connected by threads, a sealing body is arranged between the valve body and the valve seat, the sealing body is attached to the inner hole wall of the gas circuit jack, and one end of the return spring is in contact with the valve seat , the other end of the return spring is fixed, a number of sealing grooves are arranged at intervals at the right end of the air circuit pin, and a sealing ring is arranged in the sealing groove. The invention also provides an electrical connector with the air circuit contact. The gas circuit contact provided by the present invention can automatically close the gas circuit channel after the gas circuit pin and the gas circuit socket are separated, so as to realize the functions of maintaining the pressure of the gas circuit, preventing dust, and blocking foreign objects. At the same time, the cross-sectional area of ​​the gas path is large, which can transmit more gas media and take away more heat in the same time. For systems with large heat generation, it can meet the function of cooling protection.

Description

technical field [0001] The invention belongs to the field of gas-electric hybrid electrical connectors, in particular to a gas-circuit contact piece and an electrical connector having the gas-circuit contact piece. Background technique [0002] With the rapid development of weapon systems and manned spaceflight technology, the functional requirements for electrical connectors have become more and more diverse, and electrical connectors with functions such as integrated circuits, gas paths, optical paths, and liquid paths have emerged. Among them, the gas channel can transmit gas, liquid and other media in the system to protect the related components from cooling. [0003] The Chinese Patent Publication No. CN1088791067A discloses an integrated high-pressure gas circuit contact piece and electrical connector, including a gas circuit socket and a gas circuit pin that are inserted into each other, which solves the problem of gas leakage at the sealing position of the connection...

AI Technical Summary

Problems solved by technology

[0003] The Chinese patent with the publication number CN1088791067A discloses an integrated high-voltage gas circuit contact and an electrical connector, including gas circuit jacks and gas circuit pins that are mated with each other, which solves the gas leakage at the sealing position of the connection interface of the gas circuit contact The problem and the sealing position of the part matching interface affect the gas transmission problem, but the gas circuit contact can only realize the sealing function after mating, and the gas circuit through hole cannot be closed after separation, resulting in the failure to store and maintain the pressure of the transmission medium, which affects the system. normal work

And for the large-diameter gas path, the gas path channel is not closed, foreign matter such as dust and impurities will enter the channel, mix with the cooling medium and cause pollution, which will affect the working performance of the equipment

The Chinese patent with the publication number CN102537567A discloses a one-way air circuit connector, including a plug and a socket. The socket includes a gasket, an air circuit jack, a sealing plug, a spring and a tail sleeve. The sealing plug cooperates with the inner tapered surface on the air passage socket, which can automatically close and block the air leakage after separation, and realize the storage and pressure maintenance of the transmission medium, but the ratio of the cross-sectional area of ​​the air passage to the cross-sectional area of ​​the entire contact piece is relatively large. Small, especially at the joint between the sealing plug and the inner tapered surface of the gas path socket, the gas path cross section is extremely small. Under the same outer diameter of the contact piece and the same gas medium flow rate, the gas medium volume flow rate is small, and the calorific value is relatively small. A large system cannot meet the function of cooling protection
