Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a polyvinyl chloride insulated wire and cable. Background Art

[0002] PVC insulated wires and cables are economical and practical materials, which makes the cost of wires and cables with PVC as insulation material lower, thereby reducing the cost of the entire electrical system. It has good insulation properties, can effectively prevent current leakage, and ensure the safe use of wires and cables. At the same time, it has good resistance to acids, alkalis, salts, etc., so it can still maintain stable performance in harsh environments.

[0003] For example, the insulated control cable announced with application number CN203456138U includes: multiple copper wire cores, sub-shielding layers, a total shielding layer and a sheath layer, the surfaces of the multiple copper wire cores are respectively wrapped with sub-shielding layers, the multiple copper wire cores are arranged inside the total shielding layer to form a cable harness, and the sheath layer is wrapped and connected with the total shielding layer. In the above manner, the insulated control cable of the device has a structure in which the copper wire core is independently insulated, has a simple structure, is easy to produce, has strong wear resistance, and has a long service life.

[0004] However, the insulated control cable mainly considers the structure of the cable with independent insulation of the copper core, but does not consider improving the protection performance of the wires and cables. The wires and cables are easily affected by external factors, which affects their service life.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a polyvinyl chloride insulated wire and cable is proposed. Utility Model Content

[0006] The utility model aims to provide a polyvinyl chloride insulated wire and cable to solve the problem of reducing the influence of external factors on the wire and cable proposed in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a polyvinyl chloride insulated wire and cable, comprising a copper core, a polyvinyl chloride insulating sleeve is installed around the copper core, a heat-conducting sleeve is fixedly installed on the polyvinyl chloride insulating sleeve, a protective sleeve is fixedly installed on the heat-conducting sleeve, and a support ring is installed in an array on the protective sleeve.

[0008] Furthermore, the polyvinyl chloride insulation sleeve material is made of high-quality imported high-molecular polyvinyl chloride.

[0009] Furthermore, the polyvinyl chloride insulation sleeve has uniform thickness and is not easily punctured.

[0010] Furthermore, the heat-conducting sleeve contains ceramic particles.

[0011] Furthermore, the protective sleeve is made of rubber.

[0012] Furthermore, the protective cover is inlaid with a magnetic soft strip.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model provides a protective sleeve, and the PVC insulating sleeve is uniformly thick and surrounds the copper core, which effectively avoids arc breakdown. The heat generated by the PVC insulated wire and cable can be dissipated by heat conduction through the thermal conductive sleeve, thereby improving the heat dissipation efficiency. The protective sleeve is used to improve the impact resistance of the PVC insulated wire and cable, and the support ring is used to further improve the overall strength of the PVC insulated wire and cable, effectively extending the service life of the PVC insulated wire and cable.

[0015] 2. The utility model provides a magnetic soft strip, which is evenly arranged on the protective cover. When the polyvinyl chloride insulated wire and cable are rolled up, the polyvinyl chloride insulated wire and cable can be adsorbed to each other, thereby effectively avoiding the phenomenon of the cable being scattered.
