Description

Technical Field

[0001] The present invention relates to the field of electrical technology, and in particular to a cable fixing device. Background Art

[0002] Cable is an electric energy or signal transmission device, which is made of one or more mutually insulated conductors and an outer insulating protective layer. Due to the development of power and communication technology, cables are widely used in various aspects such as industry and life. Due to the complexity of power lines and signal transmission lines, it is usually encountered that multiple groups of cables are arranged in parallel. When multiple groups of cables are arranged in parallel, the cables are gathered together, which is relatively complicated and messy. The cables need to be fixed to avoid them from being scattered. The existing cable fixing method is usually cable tie bundling, which is to use cable ties to tie multiple cables together. However, if the cable is tied with a rolling belt, when the cable tie needs to be removed in the case of maintenance, the rolling belt can only be cut off. When cutting the rolling belt, it is easy to accidentally damage the cable sheath, causing cable damage. At the same time, it is difficult for the rolling belt to completely separate multiple cables, which will cause friction between adjacent cables. Long-term friction is easy to cause wear of the outer insulation layer of the cable; and using a rolling belt to bundle the cables together is not conducive to the heat dissipation of the cable.
