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.
本发明公开了一种用于新能源汽车充电桩的线缆,包括线芯、线套和分离支架,线芯包括正极导线、负极导线和接地导线,线套包括内胶套和外胶套,内胶套套设在分离支架的外部,内胶套的内腔通过分离支架分隔成第一线缆腔、第二线缆腔和第三线缆腔,正极导线、负极导线和接地导线分别贯穿于第一线缆腔、第二线缆腔和第三线缆腔,本发明涉及线缆技术领域。该用于新能源汽车充电桩的线缆,利用分离支架将线芯进行分隔,防止导线距离过近,热量过高而受损,当电流过高致使正极导线和负极导线自身温度过高时,热量通过导热片传输至集热腔,集热腔的热量聚集一定程度,第一单向阀打开向外排气,自动散热,提高线缆的使用寿命。
