Original Abstract Submitted

A housing sealing structure includes a housing body, a busbar assembly, and a sealing ring, wherein the housing body has a partition plate, and a first chamber and a second chamber on two sides of the partition plate. The partition plate is provided with a through hole through which the busbar assembly passes such that the busbar assembly is sealed at the through hole by the sealing ring. The housing body also includes a first snap-fit portion, and the busbar assembly includes a second snap-fit portion, the first snap-fit portion being snap-fitted with the second snap-fit portion, which ensures the busbar assembly is at a fixed position relative to the housing body to avoid seal failure caused by large compression difference between two sides of the sealing ring due to swing of the busbar assembly relative to the housing body during use, thereby further improving the sealing effect.
