Abstract

The invention discloses an air-tight fiber wall-penetrating socket. The air-tight fiber wall-penetrating socket is characterized by comprising: a housing having a separation wall provided with multiple pin limit holes; press plates with pin stepped holes, positioning holes and screw counterbores; and pin assemblies provided with front sleeve pipes, rear sleeve pipes, ceramic pins and tight coated fibers. The pin assemblies are disposed in the pin limit holes of the housing. The two press plates are disposed on the two sides of the separation wall of the housing respectively. The pin assemblies are inserted in the pin stepped holes. The positioning holes of the press plates fit positioning bosses of the housing. The screw counterbores are connected to threaded blind holes by means of screws. Through adoption of the housing, the press plates and the pin assemblies and also through the assembly process using an epoxy sealant and silica gel, a present situation that long and thin pins are difficult to process is avoided. The advantages are that the air-tight fiber wall-penetrating socket has many channels, exhibits good air-tightness, and is convenient to process and assemble.

Description

technical field

[0001] The invention relates to the technical field of optical fiber connectors, in particular to an airtight optical fiber wall socket. Background technique

[0002] The purpose of using optical fiber connectors to connect with equipment is to make the optical fibers passing through the equipment panel not only withstand the pressure difference inside and outside the panel, but also prevent the interpenetration of the media inside and outside the panel, that is, there is a requirement for airtightness of the optical fiber connector. With the increasing application of optical fiber communication technology in aerospace and harsh environments, the technical requirements for the airtightness of optical fiber connectors are also gradually increasing. In the prior art, the optical fiber hermetic wall socket is generally sealed with glue or an "O" ring, and its sealing level is low; there are also optical fiber airtight wall sockets that are sealed with glass sint...
