Abstract: The present disclosure provides a multifunctional high-voltage connector and a battery product, the multifunctional high-voltage connector comprises: an upper cover; a pedestal; a conductive connection structure; two mating terminals; and a harness assembly. The conductive connection structure is used to make the two mating terminals be connected in series, and the harness assembly is directly connected to one of the mating terminals. When the upper cover and the pedestal are assembled, the conductive connection structure is simultaneously in contact with the two mating terminals, thereby turning on the high-voltage circuit. When the battery product requires maintenance, the upper cover is directly detached from the base, thereby turning off the high-voltage circuit. The battery product can be electrically connected to an external device via the harness assembly. The multifunctional high-voltage connector integrates both a switch function and a high-voltage connection function, therefore the connection resistance is greatly reduced.
