Fireproof and waterproof optical cable connector box

Abstract

The invention, which relates to the field of communication equipment, particularly discloses a fireproof and waterproof optical cable connector box which comprises an upper box cover and a lower box cover. Optical cable leading-out ports are formed in the two ends of the upper box cover and the lower box cover. A mounting box is arranged in the middle of the lower box cover; a box cover is arranged on the mounting box and is hinged to the mounting box; a fiber melting disc is arranged in the mounting box; and optical cable inlets and outlets are formed in the two sides of the mounting box. A sealing gap between the top of the box cover and the mounting box is coated with silica gel, so that a sealed structure is formed for the mounting box. The upper box cover and the lower box cover are made of pressure-resistant and drop-resistant plates. A waterproof edge cavity is formed in the surface, in contact fit with the upper box cover, of the lower box cover; and waterproof rubber cotton isarranged on the surface, in contact with the lower box cover, of the upper box cover. Strip-shaped sealing grooves are formed in the surface of the lower box cover at the outer side of the waterproofedge cavity and elastic sealing strips are fixed on the surface of the upper box cover. The connector box has the good fireproof and waterproof performances.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a fireproof and waterproof optical cable joint box. Background technique [0002] The optical cable splice box belongs to the connection pressure sealing joint system. It is a connection protection device that provides optical and mechanical strength continuity between adjacent optical cables. It is generally assembled from a box cover, box bottom, splice tray and sealing ring. It is suitable for straight-through and branch connections of overhead and pipeline laying methods of various structural optical cables. However, in the sealing structure of the existing optical cable splice closure, the matching accuracy of the sealing ring and the sealing groove is relatively high. After the ring fails, the optical cable splice box will not have waterproof performance, which will affect the use of the splice box. Moreover, the existing optical cable splice boxes are mostly made of...

Problems solved by technology

However, in the sealing structure of the existing optical cable splice closure, the matching accuracy of the sealing ring and the sealing groove is relatively high. After the ring fails, the optical cable splice box will not have waterproof performance, which will affect the use of the splice box. Moreover, the existing optical cable splice boxes are mostly made of PC plastic or ABS+PC plastic shells. Common rubber materials have limited fire resistance and cannot be used. good fire resistance
