Optical fiber connector socket for ignition and detonation

Abstract

The invention relates to an optical fiber connector socket for ignition and detonation. The optical fiber connector socket for ignition and detonation comprises a hollow socket shell; a docking end for plugging an adapted optical fiber connector plug is formed on a front end of the socket shell; a connection end for connecting an electric detonator is formed on a rear end of the socket shell; a plug pin component is provided in the socket shell; the plug pin component comprises a plug pin structure for receiving an optical signal output by the optical fiber connector plug and detonating the electric detonator; the plug pin component further comprises a plug pin fixing member inserted into the socket shell and stopped and positioned from back to front; the plug pin fixing member is providedwith a welding connection part which is welded and sealed with the socket shell; and a peripheral surface sealing structure is provided on the side of front and rear directions of a welding connection part between the plug pin fixing member and the socket shell. The optical fiber connector socket for ignition and detonation guarantees the sealing effect under a large impact force through double sealing.

Description

technical field [0001] The invention relates to the field of optical fiber connectors, in particular to an optical fiber connector socket for ignition and detonation. Background technique [0002] With the rapid development of optical fiber transmission technology, the function of optical fiber connectors has become more and more powerful, and its application range has become wider and wider. For example, in environments that require high-power laser transmission (such as laser ignition systems in aerospace systems), optical fibers are used. Connector. At present, the optical fiber connectors used in laser ignition technology are mainly ST or FC optical fiber connectors. Taking the ignition system using ST type optical fiber connectors as an example, the working principle is as follows: place the powder box and the optical fiber connector on the At the ignition position of the engine, the ignition laser beam shoots out from the front end of the pin of the optical fiber conn...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an optical fiber connector socket for ignition and detonation with better sealing performance, so as to solve the problem of the optical fiber connector under the action of a relatively large impact force when only relying on the welding and sealing of the pin part and the socket housing in the prior art. The socket is prone to technical problems of seal failure
