Composite cable with overheating protection function

Abstract

The invention discloses a composite cable with an overheating protection function, which comprises a filling layer, an insulating layer, a protective sleeve, an outer sheath and a cable core, and is characterized in that the insulating layer is mounted on the inner side of the filling layer, the outer sheath is mounted on the inner side of the insulating layer, the cable core is mounted in the outer sheath, and the protective sleeve is attached to the outer side of the insulating layer; the edge of the protective sleeve arches outwards to form a protruding part, and a convection channel is formed in the inner side of the middle of the protruding part; and the conduction block is installed in the middle of the rubber connecting sleeve, the middle of the inner end of the conduction block is fixedly installed on the side of the protective sleeve, and an inserting groove is formed in the middle of the conduction block and used for containing a guide part in the middle of the inner side of the rubber connecting sleeve. According to the composite cable with the overheat protection function, heat in the cable can be quickly dissipated outwards in sunny and high-temperature days in summer, the cable is prevented from being in an overheat state, and meanwhile, the contact area between the outermost layer of the cable and external air can be increased.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a composite cable with an overheat protection function. Background technique [0002] A cable is usually made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire that transmits power or information from one place to another. When the cable is used outdoors when it rains or snows outside, rainwater And snow water will fall on the surface of the cable, which can play an auxiliary cooling effect on the cable, so the cable itself is not easy to overheat when it is working, but the cable is especially hot in summer when the outside temperature is too high and its own work The high temperature generated at the time leads to the excessive temperature of the cable itself. [0003] However, existing cables have the following problems: [0004] For example, a heat-resistant high-voltage cable with a publication number of CN113488249A, which ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a composite cable with overheating protection function, to solve the above-mentioned background technology, when the existing cables on the market are too high, the holes inside the cables are located on the same straight line, so that the Its heat-guided conduction to the periphery of the cable helps the cable dissipate heat quickly, but the outermost layer of the cable is a circular structure, and the contact area between the circular structure and the outside air is small, so excessive heat dissipation is required during the heat dissipation process. It takes a long time to dissipate the heat outward, which reduces the practicality of the cable itself
