Problems solved by technology

The existing problem of this kind of connector is that: the elastic wire sealing sleeve is arranged on the installation step on the wall of the inner hole of the inner casing, since the elastic wire sealing sleeve will shrink radially inward during use, The mating interface in contact with the inner shell will see water seepage under the condition of high negative pressure, and the water will flow into the connector through the gap between the elastic sealing sleeve and the inner shell and damage the connector

Embodiment Construction

[0019] An example of a connector is Figure 1~4 Shown: including the inner shell 1 whose front end is the plug-in end, the outer periphery of the inner shell is axially movable and has an outer shell 4 in the rotating sleeve, and the front end of the outer shell is provided with a threaded screw for connecting with the corresponding adapter connector shell. The connecting thread installed, the rear end of the outer casing is provided with an inversion edge 5. The inner shell is made of transparent PC material. The inner shell includes a front guide section that guides and cooperates with the outer shell and a rear installation section whose outer diameter is smaller than the front guide section. The connector also includes an elastic sealing sleeve 2, an elastic sealing sleeve The wire sleeve includes a wire seal body. The front end of the wire seal body is provided with a wire seal fixed section 2-1 which is fitted with an interference seal on the rear installation section. T...

Abstract

The invention relates to a connector, which comprises an inner shell whose front end is a plug-in end and an axially movable outer shell which is rotatably fitted on the outer periphery of the inner shell. The rear end of the inner shell is provided with an elastic sealing sleeve. The sleeve includes a wire sealing sleeve body, and the rear end of the sealing wire sleeve body is provided with a deformation section of the wire sealing sleeve for radial contraction and deformation by the force of the inner turning edge of the outer housing when the outer housing moves forward. The front end of the sleeve body is provided with a wire sealing sleeve fixing section which is fitted with an interference seal on the outer peripheral surface of the rear end of the inner casing. The invention provides a connector capable of ensuring the sealing effect between the inner housing and the elastic sealing sleeve.

Description

technical field [0001] The invention relates to a connector. Background technique [0002] Existing connectors that can seal the cable inlet of the connector, such as the "optical connector with replaceable optical jumper" disclosed in Chinese patent CN 202533608U, this connector includes an inner housing for threading, and the front end is a plug-in end. The outer casing of the inner casing is rotatably fitted with an outer casing that can move axially relative to the inner casing. The front end of the outer casing is provided with a connecting thread for screwing onto the thread on the adapter housing, and the rear end of the outer casing is provided with a Invert edge. An elastic sealing sleeve is installed on the inner hole wall of the inner hole at the rear end of the inner housing, and the outer circumference of the elastic sealing sleeve is provided with a fixed sleeve provided with elastic claws. When in use, the connecting thread on the outer shell is screwed and ...
