Description

Technical Field

[0001] The utility model belongs to the technical field of cable protection, in particular to a protection device for optical fiber communication cables. Background Art

[0002] Communication cables are used to transmit telephone, telegraph, fax documents, television and radio programs, data and other electrical signals. They are made up of one or more pairs of mutually insulated conductors twisted together. During long-distance wiring, due to the limited length of the cable, the optical cables need to be connected. The connection positions of these connectors need to be protected to prevent breakage caused by external forces.

[0003] The patent with publication number CN209248127U discloses a protective device for optical fiber communication cables. The protective device for optical fiber communication cables can preliminarily fix the optical cable body through a clamping plate and a cable tie. By turning the knob, the threaded rod drives the pressure plate to contact the optical cable, thereby achieving the purpose of fixing the optical cable connection. The rubber pad can increase the friction between the optical cable and prevent the optical cable from loosening and slipping, thereby preventing the optical cable from being damaged.

[0004] However, the above device lacks buffering for the cables when in use. When encountering strong winds, the cables at both ends of the box body are subjected to increased stress, which may easily cause the cable joints to loosen and break, which is not conducive to protecting the cables.

[0010] Preferably, the nut ring and the side wall of the pressure plate are arranged to slide alternately.

[0011] Preferably, a sealing gasket is provided in the wiring groove, and the optical fiber cable passes through the sealing gasket.

[0012] The utility model adopts the above structure to achieve the following beneficial effects:

[0013] 1. By setting the damping rod and spring, in conjunction with the baffle and fixing block, a buffer distance can be reserved for the optical fiber cable to avoid the straight line connection of the optical fiber cable, and to avoid excessive force on the optical fiber cable in windy weather, resulting in the cable connection breaking;

[0014] 2. By setting up a support tube body and using a nut ring to squeeze the pressure plate, the pressure plate can clamp and fix the optical fiber cable on the support tube body to ensure the stability of the optical fiber cable. BRIEF DESCRIPTION OF THE DRAWINGS
