The invention relates to a self-supported activation device for an electromechanical switch, which can be used for the isolation of a faulty element of a battery, comprising a set of electrically connected elements. The activation device (1) is intended to activate switching in a switching device (2) of the type having electrical contact means (3) that can move between first and second electrical positions. The activation device comprises a current sensor (6a, 6b), a retaining element (7), and at least two movable elements (8, 9) solidly connected to a coil (10). When a current is detected by the current sensor (6a, 6b) the activation device can move from a non-activation configuration, in which the movable elements are retained by the retaining element in a first position intended to prevent the movement of the contact means of a switching device, into an activation configuration, in which the movable elements are no longer retained in the first position by the retaining element and instead occupy a second position intended to allow the movement of the contact means of a switching device. The coil (10) comprises a passage space for at least part of the contact means, and each of the movable elements can rotate about an axis such as to clear the passage space, in the aforementioned second position, while remaining solidly connected to the coil.

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.
