Clamp type cable sheath grounding frame

Abstract

The invention provides a clamp type cable sheath grounding frame which comprises multiple grounding copper bar components which are fixed on the wall. The technical main points are that the grounding copper bar components comprise multiple grounding copper bar units I and grounding copper bar units II which are identical in structure. The adjacent grounding copper bar units I or the grounding copper bar units II are connected in series via bridging copper bars. The grounding copper bar units I or the grounding copper bar units II comprise copper bar bodies, multiple pin parts which are integrated with the copper bar bodies and positioned at the bottom parts of the copper bar bodies and equidistantly arranged, and insulating sheets which are arranged at the two ends of the copper bar bodies. The same side of the grounding copper bar components formed by the grounding copper bar units I and the grounding copper bar components formed by the grounding copper bar units II and the same grounding trunk lead-out copper bar are fixed simultaneously. The grounding copper bar components are fixed on the wall via expansion bolts assembled on the insulating sheets. Problems of disordered cable shielding layer grounding installation mode, poor uniformity, poor anti-interference performance and poor resistance consistency can be fundamentally solved.

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
