Description

Technical Field

[0001] The present disclosure relates to the technical field of high-voltage connectors, and in particular, to a high-voltage connector, a battery pack, and a vehicle. Background Art

[0002] As an important power source for the vehicle, the battery pack is equipped with a high-voltage connector on the outside of the battery pack. The battery pack is suitable for transmitting electrical energy to the electrical parts of the vehicle through the high-voltage connector to ensure the normal operation of all components of the vehicle.

[0003] In the technical field of the industry, when installing high-voltage connectors, first install the high-voltage connectors one by one on the battery pack shell, then connect the copper busbar or wiring harness inside the battery pack to the high-voltage connector, and finally connect the electrical components of the vehicle to the high-voltage connector through the high-voltage plug to realize the battery pack to supply power to the electrical components of the vehicle. In some cases, the high-voltage connector needs to be installed on the upper cover of the battery pack. After closing the upper cover of the battery pack, the seal is completed, and the copper busbar or wiring harness inside the battery pack cannot be connected to the high-voltage connector, and the battery pack cannot supply power to the electrical components. The solution given in the relevant technology is: open a mounting hole on the upper cover, and extend the terminal of the high-voltage connector into the mounting hole. However, the terminal in the relevant technology is arranged vertically with the cover plate, which makes it impossible to connect the terminal to the copper busbar through the mounting hole installation bolt, and can only be installed by drilling holes in the battery pack shell for bolt installation, which will cause the sealing of the shell to deteriorate and the installation is more difficult.
