A tensile flame retardant silicone rubber cable

Abstract

A tensile flame retardant silicone rubber cable includes an external waterproof layer, a middle insulating layer is arranged in the external waterproof layer, a connecting layer is arranged in the middle insulating layer, an internal main frame body is arranged in the connecting layer, the four fixed angles of the internal main frame body are provided with sliding hoses, support rods are arrangedat the middle of the upper and lower ends of the internal main frame body, a plurality of connecting plates are arranged at one inner end of the support rod, and telescopic springs are arranged between the connecting plates and the internal main frame body. When the device works, the sliding hoses can slide in the arc-shaped grooves when the cable is stretched by the outside, thereby preventing the cable core from being broken and achieving tensile and flame-retardant properties. When the external tension force is received, the horizontal wheel and the vertical wheel can slide on the connecting layer, so as to ensure that the internal cable core is not deformed greatly; the cable core can be kept in the original shape, and an aluminum core and a copper core can be separately installed in the internal main frame body, so that one object can be used for multiple purposes, and different joints can be connected.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a tensile and flame-retardant silicone rubber cable. Background technique [0002] A cable is usually a rope made of several or several groups of wires twisted together. Each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering. The cable has the characteristics of internal electrification and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0003] Flame-retardant silicone rubber cables use silicone rubber as insulation or sheath material....

AI Technical Summary

Problems solved by technology

However, most of the existing flame-retardant silicone rubber cables have complex structures, and there is only one cable core in the middle, and there is often no buffer device. The cables are easily damaged when receiving external impacts, so the service life is often not long.
