Description

TECHNICAL FIELD

[0001] The utility model relates to charging pile cable technical field, especially a kind of anti-kink bending charging pile cable. BACKGROUND

[0002] At present, with the development of science and technology, charging pile is widely used due to its convenience and rapid charging, and the cable used by charging pile is also produced in large quantities. Since charging pile needs to be moved frequently, the cable is also frequently moved. The service life of the general cable is often short due to unreasonable structure design. The cable is easily oxidized due to long-term exposure to air. If the design of the cable is unreasonable, water may enter the cable under high temperature or rainy and snowy weather, causing damage to the cable and bringing great inconvenience to people.

[0003] In addition, the charging pile cable is often buried in the ground during use, so it has high requirements for voltage resistance, aging resistance, acid and alkali resistance, salt mist resistance, waterproofness and other use requirements. The ordinary control cable bundled with the charging pile does not have a protective sleeve layer, which cannot meet the requirements of voltage resistance, aging resistance, acid and alkali resistance, salt mist resistance, waterproofness and other performance requirements, thereby greatly reducing the service life of the cable and posing a safety hazard. On the other hand, the bundled wires are easily disturbed by the external environment, have poor anti-interference ability, affect signal transmission, and have high distortion rate.

[0004] In addition, the charging pile cable has a large load current value (about 200A), and the conductor is prone to heat. During use, it is in a state of frequent dragging and moving, and is exposed to the external environment for a long time, which is prone to damage by mouse gnawing and car crushing. Therefore, the charging pile cable has high requirements for oxidation resistance, weather resistance, wear resistance and voltage resistance. Due to the large load current of the cable, the corresponding cross-sectional area is large, which increases the production cost and makes it inconvenient to move and drag.

[0005] Therefore, in view of the deficiencies of the prior art, it is necessary to provide an anti-kink bending charging pile cable to solve the deficiencies of the prior art. UTILITY MODEL CONTENTS

[0006] The utility model aims at avoiding the deficiencies of the prior art and provides an anti-kink bending charging pile cable. The structure of the charging pile cable is reasonable, has good corrosion resistance, and has a long service life. The first conductor is composed of multiple silver-plated copper wires. Compared with the conventional tin-plated layer, the silver-plated layer has low fluidity and large current-carrying capacity, and is not prone to oxidation due to copper wire exposure. The metal braid layer is made of non-magnetic metal wires, which can effectively eliminate the eddy current problem caused by magnetic material armor and also can strengthen and protect the cable structure, enhance its oxidation resistance, weather resistance, wear resistance and voltage resistance, effectively resist mouse gnawing and car crushing and other damage, and increase the service life.
