A circular connector and connector assembly

Abstract

The invention relates to a circular connector and a connector assembly. The connector assembly includes a plug connector and a socket connector. The plug connector includes a plug housing, and the outer circumference of the plug housing is rotatably equipped with a connecting sleeve. The outer peripheral surface is provided with anti-rotation splines, and the outer periphery of the anti-rotation splines is equipped with a sealing ring. An annular groove that provides radial deformation space for the seal ring during axial extrusion. The annular groove enables the sealing ring to have a large enough deformation space when it is axially squeezed and radially deformed by the socket housing. If it is too small, the sealing ring in the gap will be damaged, which improves the service life of the sealing ring, and makes the resistance during screwing smaller, and the screwing is more labor-saving.

Description

technical field [0001] The invention relates to a circular connector and a connector assembly. Background technique [0002] Circular connectors are generally required to have sealing, anti-vibration, anti-loosening and other characteristics, so that they can be used in aviation, aerospace, weapons, logging and other fields. The circular plug connector and the circular socket connector are generally locked and connected through the connecting sleeve after mating. The connecting sleeve is rotatably assembled on the plug connector housing. In the mating space for inserting the plug end of the socket connector, the outer peripheral surface of the plug end of the plug connector is also provided with anti-rotation splines for anti-rotation cooperation with the plug end of the socket connector. In order to achieve the sealing of the socket connector and the socket connector, a sealing ring is generally installed on the outer periphery of the plug end of the plug connector. After ...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned connector has the following problems: the space between the connecting sleeve and the spline housing is narrow, and after a sealing ring is arranged in this space, when the connecting sleeve is a screw sleeve, when the screw sleeve is screwed, the inner thread of the screw sleeve It will scratch the sealing ring; when the connecting sleeve is a buckle connecting sleeve, although there is no thread inside the connecting sleeve, when the connecting sleeve is screwed, the sealing ring will still be damaged due to the friction between the inner peripheral surface of the connecting sleeve and the sealing ring. crush damage

Therefore, these two kinds of connecting sleeves will damage the sealing ring, which will affect the service life of the sealing ring. At the same time, the resistance during the screwing process is relatively large, which is very laborious.
