a safety cable

Abstract

The invention discloses a safety cable. The safety cable comprises a round cable outer coat layer composed of four connecting parts, wherein the four connecting parts are in a fan shape, and the opposite surfaces of the four connecting parts are in contact with each other; each connecting part is internally provided with a core wire accommodating cavity; a core wire is arranged in each core wire accommodating cavity; an opening is formed in one side, close to the circle center, of each connecting part; arc-shaped extension parts are arranged on the two sides of the opening end respectively, and an extrusion cavity is formed between the two arc-shaped extension parts; a connecting strip which extends towards the core wire accommodating cavity is arranged on each of the opposite surfaces ofthe two arc-shaped extension parts separately; an arc-shaped supporting part is arranged on each connecting strip; and a corresponding positioning part is arranged on the core wire accommodating cavity which faces the two arc-shaped supporting parts. The safety cable disclosed by the invention has very high heat dissipation performance and anti-extrusion capability, and when the core wire at any side is extruded, the core wires on the corresponding side can be extruded into the middle protective cavity, so that secondary protection is realized, and the core wire is effectively protected.

Description

technical field [0001] The invention relates to the field of cables, in particular to a safety cable. Background technique [0002] Cables are used in many occasions, but the compressive capacity of the cables used in frequent pressurized environments needs to be guaranteed, otherwise the cables will be easily damaged after long-term pressure, resulting in interruption of transmission and instability of signal transmission. After the layer is compressed, it will directly compress the inner core wire, causing the core wire to deform, so the service life of the entire cable will be greatly reduced, and because the core wire is wrapped by the outer layer of the cable, the inner part is a sealed structure, and the heat dissipation performance is better. Difference. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a safety cable with a very good heat dissipation structure and anti-pressure protection performance, whic...
