Optical cable fiber core welding protection device

Abstract

The invention aims to provide an optical cable fiber core welding protection device to solve the problems that in the background art, an optical cable is easily pulled out of a fiber inlet groove or afiber outlet groove, so that optical fibers in the optical cable are easily damaged, an existing optical cable fiber core welding protection device is not suitable for protecting optical cables withdifferent diameters, and the practicability is low. The optical cable fiber core welding protection device comprises an upper box cover, a lower box cover rotationally arranged atone side of the upperbox cover, sealing plates fixedly arranged on the outer walls of the upper box cover and the lower box cover, sealing gaskets fixedly arranged at one side of the upper box cover and the top end of the lower box cover, the sealing parts detachably arranged in the front sides and the rear sides of the upper box cover and the lower box cover, and a locking mechanism arranged in an inner cavity of the lower box cover. According to the optical cable fiber core welding protection box, cables with different diameters can be clamped and fixed, the optical cable can be prevented from being pulled outof a fiber transmission hole, and optical fibers in the optical cable can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of optical connection, in particular to a protection device for fusion splicing of optical fiber cores. Background technique [0002] The fiber optic cable core fusion splicing protection box is to put the fused optical fiber in an iron box or hard plastic toughened plastic box. When the optical fiber is broken or not long enough, it is necessary to fuse the fiber body like glass fiber inside. Remove the outer protective layer and use the optical fiber core fusion protection box to play a protective role; [0003] The existing optical fiber core fusion protection box generally includes a box body and a box cover. The box body is provided with a fiber inlet groove, a fiber outlet groove and a fixing groove for an optical fiber fusion heat shrinkable tube. However, since the fiber inlet groove and the fiber outlet groove are generally One-word long strip shape, when the optical cable is subjected to external ...
