OPGW optical cable splice closure fixing device

Abstract

The invention relates to an OPGW optical cable splice closure which comprises an upper box, a lower box and a disc for clamping and fixing an optical cable. The upper box and the lower box are connected to the disc after being locked through bolts; two inner surfaces where the upper box and the lower box are in butt joint are provided with a plurality of concave half hole grooves, and the corresponding upper and lower half hole grooves are in butt joint to form a through hole for an optical cable to pass through; a lower surface of the lower box vertically extends downwards to form a first connecting plate; the lower surface of the lower box is further connected with a fixing device of an ''L''-shaped structure, a vertical side surface of the fixing device is connected with the lower box,and a second connecting plate extending upwards is arranged at the end, away from the vertical side surface, of a horizontal side surface; the first connecting plate and the second connecting plate are fixedly connected with the disc; and a protruding fixing base is arranged on the inner side wall of the horizontal side surface of the fixing device, a through mounting hole is arranged in the fixing base, and an adjusting screw assembly is connected into the mounting hole in a threaded mode to fix the fixing device.

Description

technical field [0001] The invention relates to a fixing device for an OPGW optical cable splice box, which belongs to the technical field of electric power communication. Background technique [0002] An important feature of power optical cables is that they can be laid on the same pole (same channel) as the power transmission and distribution lines. Thanks to the rich grid channels, the rapid development of the power communication network has been accelerated. Among them, the OPGW optical cable is to place the optical fiber in the ground wire of the overhead high-voltage transmission line to form an optical fiber communication network on the transmission line. This structural form has both the dual functions of the ground wire and communication. The OPGW optical cable needs to use the wiring structure for optical cable connection when the communication network is established to ensure the long-distance wiring of the optical cable. There are no specific operating requireme...

AI Technical Summary

Problems solved by technology

During the process of fiber core fusion, the optical cable will be displaced by its own torsion, the tilt of the splice box, and the impact of external force. At present, there is no uniform standard cable fixing method, and there is no temporary fixing method for the cable splice box. Therefore, it is impossible to solve the problem of the fiber core. The problem of easy swing during the splicing process leads to frequent fiber core breaks, which seriously affects the quality and efficiency of optical cable fusion
