Clamp type cable sheath grounding frame

Abstract

A clamp-type cable sheath grounding frame, including several grounding copper bar assemblies fixed on the wall, and its technical gist is: the grounding copper bar assembly includes several grounding copper bar units I and grounding copper bar units with the same structure II, between adjacent grounding copper bar units I or between grounding copper bar units II through bridging copper bars; A number of feet arranged at equal intervals at the bottom, insulating sheets located at both ends of the main body of the copper bar; the same side of the grounding copper bar assembly formed by the grounding copper bar unit I and the grounding copper bar assembly formed by the grounding copper bar unit II are simultaneously connected to the same The main grounding copper bar is fixed, and the grounding copper bar assembly is fixed on the wall through expansion bolts assembled on the insulating sheet. It fundamentally solves the problems of chaotic installation methods, poor uniformity, poor anti-interference performance, and poor resistance consistency of the grounding of the cable shielding layer.

Description

technical field [0001] The invention relates to the installation field of cables or wires protected by boxes, in particular to a clamp-type cable sheath grounding frame, which is mainly suitable for grounding the shielding layer of signal cables in railway signal systems. Background technique [0002] At present, there is no unified standard for the installation method of the grounding of the signal cable shielding layer in the railway signal system. The protection of the signal is unfavorable, the length of the grounding wire is different, and the grounding resistance of the cable shielding layer is not consistent. [0003] The existing cable grounding device, such as the invention patent application publication number CN104821539A, which discloses "the invention discloses a cable grounding box", includes an outer box, an inner box is arranged in the outer box, and the inner box It can be detachably connected with the outer box, and there are corresponding ventilation hole...

AI Technical Summary

Problems solved by technology

It fundamentally solves the confusion and poor uniformity of the installation method of the grounding of the cable shielding layer, the poor anti-interference caused by the non-independent setting of the steel armor sheath and the aluminum sheath grounding channel of the cable, and the grounding resistance of the cable shielding layer caused by uneven lengths of grounding wires. poor consistency
