Cable for new energy automobile charging pile

Abstract

The invention provides a cable for a new energy automobile charging pile. The cable comprises a cable core, a cable sleeve and a separation support, the cable core comprises a positive electrode wire, a negative electrode wire and a grounding wire, the cable sleeve comprises an inner rubber sleeve and an outer rubber sleeve, the separation support is sleeved with the inner rubber sleeve, the inner cavity of the inner rubber sleeve is divided into a first cable cavity, a second cable cavity and a third cable cavity through the separation support, and the positive electrode wire, the negative electrode wire and the grounding wire penetrate through the first cable cavity, the second cable cavity and the third cable cavity respectively. The invention relates to the technical field of cables. According to the cable for the new energy automobile charging pile, the cable core is separated through the separation support, damage caused by too short wire distance and too high heat is prevented, when the temperature of the positive electrode wire and the negative electrode wire is too high due to too high current, the heat is transmitted to a heat collection cavity through a heat conduction sheet, the heat of the heat collection cavity is gathered to a certain degree, a first one-way valve is opened to exhaust air outwards, automatic heat dissipation is achieved, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable used for charging piles of new energy vehicles. Background technique [0002] With the development of society, automobiles have become the main means of transportation for people to travel to make travel more convenient and faster, but at the same time, they also consume a large amount of oil resources and cause great pollution to the atmosphere. After the 1970s, energy and environmental pressures have been pushing the development of new automotive technologies in the direction of low fuel consumption and low emissions. The development of electric vehicles has ushered in new opportunities in this context. Compared with traditional vehicles, electric vehicles not only have low exhaust emissions when driving, but also because they use a secondary energy source from a wide range of sources. It is calculated that each electric vehicle can save 1.4t-1.8t of oil per year. The...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a cable for charging piles of new energy vehicles, which solves the problem that the cable core will heat up under the action of its own resistance when the charging time of the cable is too long, while the current cable The heat dissipation ability is poor, resulting in poor current carrying capacity of the cable, and there are safety hazards such as fire
