DEEP-SEA OPTICAL CABLE EXTRUSION MOLDING BRANCH JOINT BOX AND MOUNTING PROCESS THEREFOR

摘要

A deep-sea optical cable extrusion molding branch joint box and a mounting process therefor comprise an internally armored steel wire fixing device, bearing nuts (4), a support tray (10), an inner barrel body (8), a prefabricated barrel (9) and an injection molding sealing body (1), wherein sealing pads (5) and the bearing nuts (4) are arranged on the two ends of the support tray (10); the internally armored steel wire fixing device comprises an inner cone pressing sleeve (2) and an inner cone shaft (3); the internally armored steel wire fixing device is fastened in the bearing nuts (4); the inner cone pressing sleeve (2) is fixedly connected with the support tray (10) through the bearing nuts (4); the inner barrel body (8) sleeves on the outside of the support tray (10), and is located by steel wire retainer rings (6) used for holes; the prefabricated barrel (9) also sleeves on the inner barrel body (8), and the portion from the deep-sea optical cable to the prefabricated barrel (9) is coated with an injection molding film; the support tray (10) is also provided with a tray and a cover plate (12); fiber storage units are arranged on the upper lower end and the lower end of the tray. The deep-sea optical cable extrusion molding branch joint box adds the functions, lowers the cost and simplifies the structures. The deep-sea optical cable extrusion molding branch joint box is easy to manufacture, low in fault rate, and has the advantages of being safe, reliable, energy-saving, environment-friendly, convenient to operate.
