Copper bar insulation protection structure of electric vehicle and electric vehicle

Abstract

The invention discloses a copper bar insulation protection structure of an electric vehicle. The copper bar insulation protection structure comprises a protection sleeve and a protection cover, wherein the protection sleeve is made of an insulation material and is of a tubular structure which can be matched with the periphery of a copper bar, the protection cover is of an opening type cavity structure and can cover a connection end of the copper bar and an electrical part and a fastening element, the protection cover is connected to one end of the protection sleeve, and a connection part of the protection cover and the protection sleeve can be bent. During installation, the protection sleeve is arranged at the periphery of the copper bar in a matching way and then the fastening element is assembled; and during assembly of the fastening element, the protection cover is needed to be turned-over and move, the connection end of the copper bar and the electrical part is exposed, the fastening element is locked, and finally, the protection cover is buckled to cover the connection end of the copper bar and the electrical part and the periphery of the fastening element, so that the assembly of the whole insulation protection structure is achieved. In the insulation protection structure, the protection structure closely sleeves an end part of the copper bar, a gap between the protection structure and the copper bar is reduced, and the occupancy space is effectively saved. The invention also discloses the electric vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicle power battery systems, in particular to an electric vehicle copper bar insulation protection structure and an electric vehicle. Background technique [0002] In order to ensure the safety of electric vehicles, the insulation requirements for high-voltage electrical components in electric vehicles are very high, and the battery pack, which is the power source of electric vehicles, has stricter insulation requirements. Generally, in order to prevent short circuits and protect installers and maintenance personnel, insulation protection is required for the high-voltage electrical connections inside the battery pack. As for the copper bar, which is a large current carrier in the battery pack, it is more necessary to make an insulation protection structure. On the other hand, whether it is for the convenience of installation or the limited design space, the insulation protection structure cann...
