Airtight cabin-penetrating optical fiber connector

Abstract

An airtight cabin-penetrating optical fiber connector disclosed by the present invention comprises an adapter socket and two plugs, the adapter socket comprises a socket shell, the middle part of the socket shell is provided with a central through hole, and an optical window sheet is fixedly connected in the central through hole. Positioning through holes are symmetrically formed in the socket shell and located on the two sides of the center through hole, and positioning columns are arranged in the positioning through holes. The plug comprises a plug shell, a through hole is formed in the middle of the plug shell, a collimator is arranged in the through hole, and positioning holes are symmetrically formed in the plug shell and located on the two sides of the through hole. According to the airtight cabin-penetrating optical fiber connector provided by the invention, on the basis of ensuring convenient plugging of the connector, the optical window sheet is arranged on the adapter socket, the collimator is arranged on the plug, so that the transmission effect of the optical fiber is ensured, and the optical window sheet and the positioning column are fixed in a welding manner, so that the airtightness of the whole device is ensured.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to an airtight cabin-piercing optical fiber connector. Background technique [0002] With the application of optical transmission in special fields such as aerospace and precision instruments and equipment, it is urgent to solve the problem of optical signal transmission inside and outside the chamber in high vacuum or special atmosphere environment. Traditional hermetic electrical connectors generally adopt the method of glass sintering, but the glass sintering method has technical difficulties in the realization of optical fiber connectors. First, the glue for bonding the optical fibers inside the traditional optical fiber connector cannot withstand the sintering temperature, and the end surface treatment after sintering is difficult. Guaranteed, and the optical fiber contacts after glass sintering lose their floatability, which is contrary to the design principles of optical f...

AI Technical Summary

Problems solved by technology

However, there are two problems with this solution: (1) Holes are opened on both sides of the glass, and the requirements for the position and angle deviation of the collimator are very high. After the collimator is adjusted to a certain position, the collimator is fixed, and the pigtails at both ends of the connector are flicked. The entire connector does not have a plug-in function, which limits the flexibility of use; (2) Using large pieces of glass as the basic material, Glass is a brittle material, and the mechanical properties of the connector are limited
