Buried compression-resistant cable

Abstract

The invention discloses a buried type compression-resistant cable. The cable comprises a cable outer protective layer, wherein an installation cavity is formed in the cable outer protection layer, anelastic supporting cage is mounted in the mounting cavity, the elastic supporting cage extends along the length direction of the cable outer protection layer, a gap cavity is formed between an outer wall surface of the elastic supporting cage and an inner wall surface of the installation cavity, more than one cable core wire is arranged in the gap cavity, an elastic supporting part elastically extends out of the elastic supporting cage, and the elastic supporting part extends out of one end of the elastic supporting cage to form an arc-shaped wrapping part. The cable is advantaged in that theelastic supporting cage is arranged in the cable, when in use at ordinary times, the elastic buffer capability is very good, the cable core wire can be pressed into a receding protection cavity afterbeing subjected to large shearing pressure, secondary protection is conducted through the elastic supporting cage, moreover, the elastic supporting part can wrap the cable core wire after the cable core wire retracts into the receding protection cavity, the strength is further improved, and overall safety of the cable is improved.

Description

technical field [0001] The invention relates to the field of cables, in particular to an underground pressure-resistant cable. Background technique [0002] The structure of the cable generally includes the cable outer protective layer and the cable core wire. In order to increase the safety of the cable core wire, the cable outer protective layer generally has a safety setting on it to increase the buffering capacity and shear resistance of the cable outer protective layer. , so there are many armored cables at present, but the armored cable can only provide one protection for the cable core wire. Once damaged, the core wire will be damaged by shearing immediately. The protection effect of the line is not good. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a buried pressure-resistant cable. The present invention adopts a multi-layer structure, which not only improves the buffer capacity of the cable, but also...
