Sintered gas-sealed optical fiber socket

Abstract

The invention discloses a glass sintered gas-sealed optical fiber socket. Optical fiber contact pins of the glass sintered gas-sealed optical fiber socket are mounted in an intermediate shell, a left shell and a right shell; contact pin holes are respectively arranged in the intermediate shell, the left shell and the right shell; the contact pin holes arranged in the intermediate shell, the left shell and the right shell are matched with the optical fiber contact pins in a clearance fit way; five-key grooves are arranged on circumferences at the inner sides of the left shell and the right shell; the five-key grooves position and guide a plug; an external thread is arranged on the left shell; and a mounting nut and a sealing gasket are arranged on the external thread. The glass sintered gas-sealed optical fiber socket has the advantages that the structure is simple and the gas sealing effect is good; a detachable shell design structure breaks through a difficult problem of grinding a sintered contact pin; a glass sintered structure has better compression resistance, ageing resistance and corrosion resistance compared with an elastic sealing component structure; the sintered structure is positioned and realized through a die; a more accurate contact pin mounting position can be obtained; two occasions that a connector prevents gas leakage and liquid leakage can be realized; and by means of the structures of the mounting nut and the sealing gasket, the connector simultaneously realizes the sealing at an open pore position after fixation and mounting.

Description

technical field [0001] The invention relates to a sintered air-sealed optical fiber socket, which belongs to the technical field of optical fiber connectors, in particular to a sintered air-sealed optical fiber socket. Background technique [0002] Under some specific working conditions, it is necessary to realize the airtight sealing of the optical fiber connector after installation, so as to realize the mutual air leakage or medium penetration between the two chambers with pressure difference or different medium chambers, and the sealing structure of the existing optical fiber connector generally adopts The end rubber seal or the O-ring seal between the pin and the housing, this type of sealing structure cannot completely prevent gas leakage, and is not suitable for waterproof and hydraulic sealing, and the elastic seal is easy to age, crack, and is not resistant to harsh conditions Hermetic fiber optic connectors are urgently needed in airtight cabins and deep water condi...
