The invention relates to the technical field of cable sleeves, and discloses a polyurethane sleeve of a new energy automobile wire harness, and the polyurethane sleeve arranged on a cable is obtained through sequential connection and combination of an end side sleeve link and a middle sleeve link. Each sleeve link of the polyurethane sleeve is provided with an insulation protection layer, a polyurethane enhancement layer and an outer protection layer which are sequentially nested from inside to outside, the outer protection layer is made of a light-transmitting material, and the polyurethane enhancement layer is formed by orderly weaving a plurality of polyurethane strips which are polymerized into strip shapes. Polyurethane in the polyurethane enhancement layer is coated with the ultraviolet fluorescent coating, the ultraviolet fluorescent coating has the function of uniform color development under the irradiation of an ultraviolet lamp, and the function of uniform color development of the ultraviolet fluorescent coating under the irradiation of the ultraviolet lamp can be influenced by structural flaws of polyurethane; and when flaws are detected, only corresponding sleeve links need to be replaced, so that the problem that the maintenance cost of the cable sleeve is relatively high in the prior art is solved.

    本发明涉及线缆套管的技术领域,公开了一种新能源汽车线束的聚氨酯套管,本发明通过端侧套管环节与中间套管环节的依次衔接组合得到设置在线缆上的聚氨酯套管,聚氨酯套管的各个套管环节具有由内而外依次嵌套设置的绝缘防护层、聚氨酯增强层、外侧保护层,外侧保护层为透光材质,聚氨酯增强层由聚合为条状的若干条聚氨酯有序编织组成,并且聚氨酯增强层中的聚氨酯涂覆设置有紫外荧光涂层,紫外荧光涂层具有在紫外线灯照射下均匀显色的功能,且紫外荧光涂层所具有的在紫外线灯照射下均匀显色的功能会受到聚氨酯的结构瑕疵的影响,当检测出瑕疵后只需对相应的套管环节进行更换,解决了现有技术中线缆套管维修成本较大的问题。
