[0002] The insulated integrated busbar plays a vital role in the battery module. It not only realizes the high-voltage series and parallel connection of the battery cells, but is also responsible for the temperature sampling of the battery and the accurate capture of the battery cell voltage. In addition, when excessive current occurs, the integrated busbar can also protect the circuit by fusing to prevent damage caused by overcharging of the battery or abnormal current.

[0003] Referring to the utility model patent with the authorized announcement number CN207039141U, an insulated integrated busbar is provided, including an insulating shell, a main row group with multiple conductive main rows, a branch row group with multiple conductive branch rows, and an insulating fixing seat. The insulating shell is provided with a main row receiving cavity for accommodating the conductive main row, and a branch row receiving cavity for accommodating the conductive branch row. The insulating fixing seat is provided with a receiving groove that is opposite to and connected to the main row receiving cavity. The ends of the conductive main rows are inserted into the receiving grooves and fixed to the insulating fixing seat. The conductive main rows and the conductive branch rows are both fixed in the insulating shell, and the conductive main rows and the conductive branch rows are electrically connected. The present application sets an insulating fixing seat on the outside of the insulating shell, so that during the assembly process of the components constituting the insulated integrated busbar, the multiple conductive main rows are first fixed to the insulating fixing seat, and then a series of assembly is performed.

[0004] The above patent has the following defects in practical application: Since the integrated busbar is a key component in the circuit, its waterproof performance is very important. The waterproof performance of the integrated busbar designed in the above patent is general, so there is a risk of water ingress and leakage. For this reason, we propose a compact insulated integrated busbar to solve the above technical defects. Utility Model Content
