Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a compression-resistant cable. Background Art

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire that transmits electricity or information from one place to another and plays an important role in transmitting electricity.

[0003] According to the Chinese patent application number: CN202223163971.7, a compression-resistant cable is disclosed, which specifically relates to the field of cable technology, including four groups of cable cores, the outer ends of the cable cores are covered with insulating sleeves, and a plurality of support rings are arranged outside the four insulating sleeves, and four elastic arc plates are fixedly arranged between each two adjacent support rings. The utility model protects the cable core through a plurality of evenly distributed support rings and cross support plates, thereby avoiding the situation that the cable directly acts on the cable core when being stepped on or squeezed, thereby avoiding the situation that the cable core is damaged, and has good compression resistance, effectively prolongs the service life of the cable, and has a good use effect. The support rings are connected by a plurality of elastic arc plates, so that the bending performance of the cable will not be affected, thereby facilitating the use of the cable. At the same time, the buffer mechanism will also buffer and support the elastic arc plate, which can prevent the elastic arc plate from being greatly deformed and unable to be reset, and has strong practicality.

[0004] At present, there are still some shortcomings in a compression-resistant cable. For example, when the compression is resisted by a buffer spring, after long-term use, the rebound effect of the buffer spring decreases, causing the elastic arc plate to be easily damaged after a large deformation, affecting the compression resistance effect. Utility Model Content

[0012] By adopting the above technical solution and arranging connecting pieces, the connecting pieces connect the arc-shaped anti-compression pieces, thereby improving the compression resistance of the arc-shaped anti-compression pieces.

[0014] By adopting the above technical solution and setting a cross mounting frame, the cable is installed inside the pressure-resistant layer through the cross mounting frame. When the internal cable core is damaged, it is convenient for the staff to pull out the cable core for replacement.

[0015] Preferably, the outside of the pressure-resistant layer is coated with a high-temperature resistant layer, and the outside of the high-temperature resistant layer is coated with a flame-retardant layer.

[0017] Preferably, the flame retardant layer is coated with an armor layer on the outside, and the armor layer is coated with a wear-resistant layer on the outside.

[0018] By adopting the above technical solution and providing a wear-resistant layer, the wear-resistant layer can protect the entire cable, thereby reducing the occurrence of damage to the internal structure of the cable and improving the structural stability of the cable.

[0019] In summary, the utility model mainly has the following beneficial effects:
