Problems solved by technology

Most of the existing optical cable splice boxes are sealed with non-vulcanized rubber, and non-vulcanized rubber needs to be added again for repeated use. The cost of repeated use is high and it is inconvenient to use
The optical cable splice box sealed with vulcanized rubber is easy to reuse, and the conventional sealing performance can meet the national industry standard, but the temperature cycle performance cannot meet the requirements (national standard: Y / DT814-2007)
The main reasons for the failure to meet the performance requirements are as follows: the optical cable splice box needs to meet the use of optical cables with different diameters, the main part of the air leakage is at the buried hole of the optical cable, the thermal expansion coefficient of the existing vulcanized rubber is relatively large, and the compression permanent deformation is relatively large After the low temperature test, the volume will shrink accordingly, and the rebound performance will decrease at low temperature, which is an important reason for the deterioration of its sealing performance.

Abstract

The invention discloses a self-adaptive sealing structure of an optical cable connector box. The self-adaptive sealing structure is characterized by comprising an upper box body, a lower box body anda sealing piece, wherein the optical cable connector box is provided with an optical cable embedding hole used for an optical cable to penetrate through, the optical cable embedding hole is formed bysplicing the upper box body and the lower box body, an extrusion block and a pressure spring are arranged on the upper box body, and the extrusion block is fixed to the upper box body; the pressure spring is arranged between the extrusion block and the upper box body and is used for continuously extruding the extrusion block, and the sealing piece is arranged in the optical cable embedding hole. The optical cable embedding hole area of the optical cable connector box is of the self-adaptive sealing structure, so that normal temperature sealing of the optical cable is completed, then the pressure spring is loosened, the extrusion block continuously extrudes the sealing piece under the action of the pressure spring, and therefore the sealing performance is more reliable.

Description

technical field [0001] The invention relates to an adaptive sealing structure of an optical cable splice box Background technique [0002] The optical cable splice box mainly protects the connection between the optical cable and the optical cable on the optical fiber network. There are two ways to connect the optical cables: straight-through and divergent. Most of the existing optical cable splice boxes are sealed with non-vulcanized rubber, and non-vulcanized rubber needs to be added again for repeated use, which is costly and inconvenient to use. The optical cable joint box sealed with vulcanized rubber is easy to reuse, and the conventional sealing performance can meet the national industry standard, but the temperature cycle performance cannot meet the requirements (national standard: Y / DT814-2007). The main reasons for the failure to meet the performance requirements are as follows: the optical cable splice box needs to meet the use of optical cables with different dia...
