Therefore, the mainframe circuit has very strict requirements for the quality and reliability of electrical connectors. Also, because of the high quality and high reliability of electrical connectors, they are widely used in military systems such as aviation, aerospace, and national defense. Common classification methods for electrical connectors include shape, structure, use, etc.
[0003] The electrical connectors of the prior art are generally fixed by threaded connection. When working in a high-air-pressure environment, due to the high air pressure, moisture directly enters the interior of the electrical connector, and the internal metal parts oxidize and rust with the water vapor, which then leads to signal transmission obstruction and reduces its service life. Therefore, there is an urgent need for an electrical connector resistant to high air pressure to overcome the above defects. Summary of the Invention
[0004] The purpose of the utility model is to provide an electrical connector resistant to high air pressure, which has the advantages of good sealing effect and convenient installation, so as to solve the problems raised in the above background art.

The clamping assembly includes a sleeve, a first sliding groove, a first spring, a first slider, and an arc-shaped block. The plug assembly includes a mounting seat, a second sealing ring, a through groove, a positioning slide bar, a second slider, a second spring, a second sliding groove, a plug body, and a third sealing ring. The second sealing rings are fixedly installed on both sides of the inner cavity of the mounting seat, the plug body is fixedly installed on the right side of the inner cavity of the mounting seat, the through grooves are opened in the interior of the mounting seat and the number is four, the positioning slide bar is arranged in the inner cavity of the through groove, the second sliding grooves are opened on both sides of the through groove, and the sleeve is arranged on the surface of the mounting seat.
[0006] Furthermore, the second slider slides in the inner cavity of the second sliding groove, and the relatively close sides of the second sliders are fixedly connected to both sides of the positioning slide bar.
[0007] Further, two third sealing rings are sleeved on the inner cavity of the through groove and on the surface of the positioning slide rod, and a second spring is fixedly installed at the bottom of the second slider in the inner cavity of the second chute.
[0008] Further, the first chutes are opened inside the sleeve and the number thereof is four, and the first sliders slide inside the first chutes.
[0009] Further, the relatively close sides of the first sliders are fixedly connected to the surface of the mounting base, and a first spring is fixedly installed on the left side of the first sliders in the inner cavity of the first chutes.
[0010] Further, the arc-shaped blocks are fixedly installed inside the sleeve and the number thereof is four, and the positioning grooves are opened at the center of the surface of the socket body and the number thereof is four.
[0011] Further, the first sealing rings are fixedly installed on the right side of the surface of the socket body and the number thereof is two, and the rubber sealing ring is fixedly installed on the left side of the surface of the socket body.
[0012] In summary, due to the adoption of the above technologies, the beneficial effects of the present utility model are as follows:

Under the action of the volume of the socket body, the positioning slide rod drives the second slider to move outward. When the socket body is plugged into the plug body, under the action of the second spring, the second slider drives the positioning slide rod to move inward. The positioning slide rod penetrates into the socket body through the positioning groove. At the same time, the mounting base is inserted into the rubber sealing ring to seal the left side of the mounting base. Then the staff releases the sleeve, and under the action of the first spring, the sleeve drives the arc-shaped block to move to the left. After moving to the specified position, the arc-shaped block contacts the outer side of the positioning slide rod to further fix the positioning slide rod. In order to prevent the entry of moisture, the gap generated between the socket body and the mounting base is sealed under the action of the second sealing ring, and at the same time, the gap generated between the socket body and the mounting base is further sealed twice under the action of the first sealing ring, thereby effectively preventing moisture from entering the inner cavity of the mounting base, having the advantages of good sealing effect and convenient installation, and solving the problem that the existing electrical connectors are generally fixed by threaded connection. When working in a high-pressure environment, due to the high air pressure, moisture directly enters the interior of the electrical connectors, the internal metal parts are oxidized and rusted with water vapor, thereby causing signal transmission obstruction and reducing their service life.
