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

Embodiment 1

[0059] Such as Figure 1 to Figure 12 As shown, a gas circuit contact piece includes a gas circuit pin 8 and a gas circuit socket 2. Both the gas circuit pin 8 and the gas circuit socket 2 have through inner holes to form a gas medium transmission channel. The inner hole of the hole 2 is provided with a valve body 1, a sealing body 3, a valve seat 4 and a return spring 5, wherein the valve body 1 and the valve seat 4 are fixedly connected by threads, and a sealing body is arranged between the valve body 1 and the valve seat 4 3. The sealing body 3 is attached to the inner hole wall of the air passage socket 2 to form a seal between the interior of the air passage socket 2 and the external environment. One end of the return spring 5 is in contact with the valve seat 4, and the other end of the return spring 5 is fixed on the In the inner hole of the gas circuit jack 2, the return spring 5 can provide elastic force to ensure that the sealing body 3 fits closely with the inner ho...

Embodiment 2

[0081] Such as Figure 13 to Figure 15 As shown, on the basis of the structure of Embodiment 1, the following changes are made:

[0082] The connecting pillar 102 is a cylinder, and the two ends of the cylinder are provided with rounded corners to increase the structural strength of the valve body. Compared with the special-shaped pillar structure in Example 1, the cylindrical structure is easy to process, but the cross-sectional area of ​​the opposite-shaped pillar is greater than that of the gas path. Under the condition that the cross-sectional area of ​​the inner hole of the air passage jack 8 is equal, it has higher structural strength.

[0083] The middle part of the fourth section hole 204 is provided with an annular groove 206, and a retaining ring 10 is arranged in the annular groove 206. The retaining ring 10 is fixed in the annular groove 206 by its own elastic force, and the inner circle of the retaining ring 10 protrudes from the annular groove 206. 10 fits with ...

Embodiment 3

[0087] Such as Figure 16 to Figure 18 As shown, on the basis of the structure of Embodiment 1, the following changes are made:

[0088] Increase the outer diameter of the third section hole 203, increase the gap between the third section hole 203 and the valve body 1, the sealing body 3 and the valve seat 4, increase the gas path path, and the minimum gas path section (sealing body 3 and valve seat 4) The ratio between the gap between the holes 203 in the third section) and the cross-sectional area of ​​the inner hole of the air passage jack 8 can also reach 1:1, that is, the cross-sectional area of ​​any inner hole of the air passage jack 2 is greater than or equal to the inner hole of the air passage jack 8 The cross-sectional area ensures smooth transmission of the gas medium and meets the cooling requirements.

[0089] The first sealing surface 205 is a conical surface, and the second sealing surface 302 is a conical surface. The seal formed by bonding the first sealing ...

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...
