Floating water sealing coaxial electric connector

Abstract

The invention discloses a floating water sealing coaxial electric connector comprising a connector shell provided with a cable incoming end and an inserting end. The connector shell comprises a fixed shell and a floating shell, wherein the floating shell is inserted into and matched with the fixed shell and is elastically matched with the fixed shell in a floating way through an elastic body which is axially arranged between the outer wall of the floating shell and the corresponding structure of the inner wall of the fixed shell; the position of the fixed shell, which is close to the cable incoming end, is provided with a containing space for installing an elastic glue cushion, and the elastic glue cushion is provided with an inner hole for a coaxial cable to penetrate through, an inner hole wall and an outer wall which are respectively sealed and matched with the coaxial cable and the fixed shell during axial compression; the floating shell is provided with a compression part which supports against and is axially matched with the elastic glue cushion when the floating shell moves towards the cable incoming end relative to the fixed shell; and the fixed shell is provided with a stop part matched with the elastic glue cushion in a limiting way and arranged opposite to the compression part. The floating water sealing coaxial electric connector ensures the good water sealing effect of the cable incoming end when the inserting end is inserted in a floating way.

Description

technical field [0001] The present invention relates to coaxial electrical connectors for terminating coaxial cables. Background technique [0002] In the existing coaxial electrical connectors used for terminating coaxial cables, the coaxial cables penetrate into the corresponding openings of the connector housing. The gap enters the connector. The existing coaxial connector is to crimp the sealing sleeve at the tail of the housing to realize water sealing. For example, a waterproof coaxial connector disclosed in Chinese Patent Publication No. CN 201113049Y, the inner hole of the waterproof rubber sleeve used The outer circumference of the housing of the coaxial electrical connector and the outer circumference of the connected coaxial cable are simultaneously interference fit to realize water sealing. Although the watertightness can be achieved in this way, since the connector housing and the coaxial cable are pressed and fixed together by the waterproof rubber sleeve, the...

Problems solved by technology

Although the watertightness can be achieved in this way, since the connector housing and the coaxial cable are pressed and fixed together by the waterproof rubber sleeve, the contacts of the plug-in end connected with the central conductor of the coaxial cable and the braided net will not be able to contact the housing. Axial or radial movement, when mating with the contact of the corresponding connector, the mating is difficult to align and the impact resistance is poor and easy to be damaged; in addition, the waterproof rubber sleeve installed by interference fit is difficult to assemble and disassembly
