Optical fiber cabin-penetrating sealing connection socket device used for sealing cabin

Abstract

Disclosed is an optical fiber cabin-penetrating sealing connection socket device used for a sealing cabin. The device comprises sealing flanges, optical fiber sealing seats, optical fibers, inner-side dockingplug cores and outer-side docking plug cores, the sealing flanges and the sealing cabin are sealed by adopting welding sealing or sealing rings, each sealing flange is provided with at least one optical fiber sealing seat mounting hole, the optical fiber seats are fixed in the mounting holes through laser welding sealing, the middle of each optical fiber is fixed in a central micropore of the corresponding optical fiber sealing seat through low-temperature glass welding material sealing, each of the inner-side and outer-side docking plug cores is fixed in the mounting holes at two ends of corresponding optical fiber sealing seat through interference fit, two ends of each optical fiber are bonded and fixed with the inner-side and outer-side docking plug cores respectively through epoxy glue, PC type or APC type docking faces are formed through fine grinding processing, and two ends of each sealing flange are connected with corresponding plugs in a matched manner respectively by adopting connection modes like thread connection or bayonet connection for optical signal transmission. The optical fiber cabin-penetrating sealing connection socket device used for the sealing cabin is compact in structure, effective in sealing, simple in method and low in cost, and optical signal transmission between inside and outside of the sealing cabin is effectively realized.

Description

technical field [0001] The invention relates to an optical fiber cabin penetration sealing connection socket device for sealing a cabin body, in particular to an optical fiber penetration penetration connection socket device with better sealing performance. Background technique [0002] Optical fiber has the characteristics of wide transmission frequency, low loss, strong anti-electromagnetic interference, high sensitivity, and good thermal stability, and has been widely used in the fields of communication and sensing.
