Description

Technical Field

[0001] The utility model relates to the technical field of optical cable fiber distribution boxes, in particular to a protective structure of an optical cable fiber distribution box. Background Art

[0002] The fiber optic cable splitter box is a device used for the distribution and connection of optical signals in optical fiber communication networks. It is mainly used for the terminal connection, branching and distribution of optical cables. It can branch and distribute the multi-core optical fibers of the trunk optical cable to meet the needs of different users.

[0003] Through searching, CN206331157U was found, which discloses an optical cable fiber distribution box. The key points of its technical solution are that it includes a box body and a cover matched with the box body, a flip plate is rotatably connected inside the box body, an optical fiber straight melting disk is provided on the inner wall of the box body, and a sliding plate is extended on the surface of the flip plate on the side facing the optical fiber straight melting disk in a direction parallel to the flip plate, and a gap is provided between the sliding plate and the flip plate to help the flip plate to dissipate heat when the leather cable passes through the flip plate to the sliding plate. There is a gap between the flip plate and the sliding plate, and the leather cable passes through the flip plate to the sliding plate and then enters thousands of households. The gap helps to dissipate the heat generated by the leather cable, thereby extending the service life of the optical cable fiber distribution box.

[0004] Since the bottom of the optical cable splitter box is mostly provided with an inlet hole and an outlet hole for the optical fiber to enter and exit, if the aperture of the inlet hole and the outlet hole is too small, it will affect the passage of the main optical cable. If the hole is too large, insects and mice can easily enter the optical cable splitter box and bite the optical cable. Therefore, we urgently need a protective structure for the optical cable splitter box. Utility Model Content
