Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a cable fixing device for a relay protection screen. Background Art

[0002] During the installation of the relay protection screen, multiple cables need to be connected. In order to prevent the cables from accidentally falling off or breaking due to pressure during the use of the relay protection screen, a cable fixing device is required. The existing cable fixing devices generally use spring clips to restrict and fix the cables.

[0003] Technicians engaged in the installation of relay protection panels found that the spring clamp fixing method is not stable for the cable clamping effect. When the cable is subjected to strong pressure, it will still slide under pressure, resulting in unstable cable clamping. At the same time, the cable bending position is prone to over-bending, causing damage to the battery cell, and multiple fixed bending is prone to fatigue fracture. For this reason, we propose a cable fixing device for relay protection panels. Utility Model Content
