A fast-sealing optical cable splice box without screws

Abstract

The invention discloses a screw-free rapid sealing type optical cable connector box. The screw-free rapid sealing type optical cable connector box comprises a box cover, a box bottom, rapid buckles, amain body sealing silica gel ring, optical cable connectors, integrated optical cable fixing frames, an optical cable fiber melting disc and an autologous hinge, wherein the autologous hinge is arranged at one side of edges of the box cover and the box bottom of the optical cable connector box, and the rapid buckles are arranged at the rest three sides; a contact surface between the box cover andthe box bottom is sealed through the main body sealing silica gel ring; the plurality of optical cable connectors are arranged at the left and right sides of the box bottom of the optical cable connector box; optical cables pass through the optical cable connectors and then are directly connected with the integrated optical cable fixing frames; the integrated optical cable fixing frames are fixedly connected to the inner side of the box bottom of the optical cable connector box; the optical cable fiber melting disc is arranged at the box bottom of the optical cable connector box. According tothe screw-free rapid sealing type optical cable connector box disclosed by the invention, the optical cable connector box can be rapidly opened and closed, and the sealing reliability of the opticalcable connector box is ensured; meanwhile, the optical cable fixing and anti-stretching performance of the optical cable connector box is also remarkably improved.

Description

technical field [0001] The invention relates to an optical cable joint box, in particular to an optical cable joint box with fast sealing without screws. Background technique [0002] The optical cable splice closure is a protection device that provides optical fiber connection between optical cables, optical cable sealing and mechanical strength continuity. It has the functions of restoring the integrity of optical cable protection, providing electrical connection, grounding or disconnection of metal components in the optical cable, protecting the optical cable connector from environmental influences, placing optical fiber connectors and storing excess length of optical fiber, etc. In today's developed communication network system, optical communication plays an important role. With the strong demand of the communication market, my country has carried out large-scale construction of communication facilities for optical entry and copper withdrawal in recent years, and the us...

AI Technical Summary

Problems solved by technology

[0004] 1. The traditional optical cable splice box uses 12 to 18 screws to mechanically seal the box cover and the bottom of the box; this method has high work intensity, and it is time-consuming and laborious to open the splice box in the later maintenance process

[0005] 2. The sealing materials are all low-cost disposable non-vulcanized self-adhesives; this method not only needs to replace the sealing materials when the optical cable splice box is opened repeatedly, but also has great difficulty and heavy workload to clean up the residual non-vulcanized self-adhesives

[0006] 3. Most of the optical cables are fixed by plastic injection-molded pressure plates; this method cannot effectively guarantee the mechanical properties (tensile properties) of the optical cable splice box, and there is a large risk, and it is very easy to break the fiber due to the force of the optical cable and cause communication failures.
