Gas circuit contact and electrical connector provided with same

Abstract

The invention provides a gas circuit contact. The gas circuit contact comprises a gas circuit plug pin and a gas circuit plug hole, through inner holes are formed in the gas circuit plug pin and the gas circuit plug hole correspondingly, and the inner hole of the gas circuit plug hole is provided with a valve body, a sealing body, a valve seat and a reset spring, wherein the valve body is connected with the valve seat through threads, the 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 plug hole, one endof the reset spring makes contact with the valve seat, the other end of the reset spring is fixed, a plurality of sealing grooves are formed in the right end of the gas circuit plug pin at intervals,and sealing rings are arranged in the sealing grooves. The invention further provides an electrical connector provided with the gas circuit contact. According to the gas circuit contact, after the gas circuit plug pin and the gas circuit plug hole are separated, a gas circuit channel can be closed automatically, and the functions of pressure maintaining, dust preventing, foreign matter blocking and the like on a gas circuit can be achieved; and meanwhile, the sectional area of the gas circuit is large, more gas media can be transferred, more heat is brought away in the same time, and the function of cooling protection is achieved for a system with the large heating quantity.

Description

technical field [0001] The invention belongs to the field of gas-electric hybrid electrical connectors, and in particular relates to a gas circuit contact and an electrical connector with the gas circuit contact. Background technique [0002] With the rapid development of weapon systems and manned spaceflight technology, the functional requirements for electrical connectors are becoming more and more diverse, and electrical connectors with functions such as integrated circuits, gas circuits, optical circuits, and liquid transmissions have appeared. Among them, the gas channel can transmit gas, liquid and other media in the system to protect the relevant components from cooling. [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 conne...

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
