Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and in particular to a harness bracket for a battery box, a battery and an electrical device. Background Art

[0002] The battery pack is the power source of electric vehicles. It is composed of multiple single cells connected in series or in parallel in different forms. When electric vehicles are driving on different roads, vibrations and bumps often occur, and the road load will be transmitted to the battery pack.

[0003] At present, some larger battery packs have longer connecting bars inside and more complicated wiring harness connections. During transportation or operation of the battery pack, due to the bumps and vibrations caused by the road surface, the longer copper bars are prone to shaking and deformation, and the wiring harness is prone to misalignment. As a result, the wiring harness and the copper plate may interfere with each other, which may lead to the wiring harness falling off or connection failure, affecting the reliability of the battery pack.
