[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0022] Referring to Figure 1 A battery pack high-voltage wire harness has:

[0023] Wire 4; bellow 3, which is sleeved on the wire 4; first high-voltage connector 1, which is connected with the first end of the wire 4; the connector functions to be connected with the battery pack. Second high-voltage connector 6, which is connected with the second end of the wire 4; terminal 9, which is connected with the second high-voltage connector 6; heat shrink tube 7, which is sleeved on the connection between the terminal 9 and the second high-voltage connector 6. The heat shrink tube 7 functions to fix the bellow 3, protect the wire 4, and insulate, etc. The bellow 3 is fixed by the heat shrink tube 7 instead of being wrapped by the tape, which not only reduces the personnel and working hours, but also does not damage the connector. The heat shrink tube 7 is a special polyolefin material heat shrink sleeve, which can also be called EVA material. The outer layer is made of high-quality soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive, which has the characteristics of insulation, corrosion resistance, wear resistance, low melting point, waterproof sealing, high adhesion, etc.
