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.

The present disclosure provides a conductive connection structure, a multifunctional high-voltage connector and a battery product, the conductive connection structure comprises: a main body portion; and two conductive connection portions. The main body portion comprises: a tube body having openings; and a conductive fusing body. The conductive connection portion has: a first contact segment connected to the conductive fusing body and sealing a corresponding opening; a second contact segment; and a transitional connection segment. It is not necessary to additionally provide the package plate, thereby making the structure of the conductive connection structure simple and the volume of the conductive connection structure small, reducing the assembling steps, and improving the space utilization of the multifunctional high-voltage connector. When the upper cover and the pedestal are assembled, the second contact segment is directly inserted into the corresponding mating terminal, thereby further reducing the connection resistance in the high-voltage circuit.
