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.

A battery connection device for connecting to a vehicle battery includes a top member, a bottom member having a side wall and a bottom wall. The side wall, top member, and bottom member form a box-like enclosure. The bottom wall includes a through-hole with a circumferential face, an adapter member arranged inside the box-like enclosure extends at least partially through the through-hole for connection with the battery. A dimension of the adapter member is smaller than a dimension of the through-hole to form a gap between an outer face of the adapter member facing the circumferential face and the circumferential face, and flexible connection member connected to the adapter member and to the bottom member and closing the gap between the outer face and the circumferential face. The flexible connection member includes an electromagnetic shield for shielding electromagnetic radiation and a seal for sealing the gap against dust and/or moisture.

A terminal assembly includes a male terminal structure and a female terminal structure. The male terminal structure includes a male terminal body, a first terminal member, and a free terminal member. The first terminal member is disposed at the male terminal body. The free terminal member is disposed at the male terminal body and detachably in contact with the first terminal member. The female terminal structure includes a female terminal body, an extension portion, a tunnel, a second terminal member, and a secured terminal member. The extension portion is protruding from the female terminal body. The tunnel is recessed from the extension portion. The second terminal member is disposed at the female terminal body and received in the tunnel. The secured terminal member is disposed at the female terminal body, spaced from the second terminal member, and disposed on the extension portion.

A clamp for a male terminal having features for preventing incorrect clamping, which comprises a main body having a ring and two jaws, that are movable toward each other for the ring to hold the terminal. An engagement element is movable in the vertical direction and to act upon the jaws to move them toward each other. A clamping member, operable to move the engagement element comprises a stem and a nut. The stem is fixed to a base body, which is pivotable relative to the main body between a first position, in which the stem is inclined with respect to the vertical and a second position, in which the stem extends in the vertical direction. In the first position, the engagement element prevents the nut from engaging a threaded portion of the stem. In the second position, the threaded portion is adapted to be engaged by the nut.

This patent pertains to magnetic coupling systems. One implementation includes magnetic jumper cables, which include magnetic couplers and elongate, insulated, electrically-isolated electric conductors.

A metal terminal includes a front-side terminal member and a rear-side terminal member. The front-side terminal member includes a female connection portion, and the rear-side terminal member includes a male connection portion. The female connection portion has an insertion port in which the male connection portion is inserted. The insertion port is formed in a shape that prevents the insertion port and the male connection portion from coming into contact with each other when the male connection portion is inserted therein. The female connection portion includes a terminal contact portion which brings the male connection portion and the female connection portion into contact with each other by pressing the male connection portion toward the female connection portion inside the female connection portion.

A socket body (1) having a socket space (3), which is delimited by a socket wall (2) and extends along a central axis (M), for receiving a plug pin, the socket space (3) having a socket opening (6) via which the plug pin can be pushed into the socket space (3), wherein at least one indentation (4), viewed in cross-section transversely to the central axis (M), extends through the socket wall (2) angularly inclined at an angle (a) with respect to the central axis (M) in such a way that at least one spring clip (5) is formed, which spring clip (5) is bent into the socket space (3), and wherein the spring clip (5) has at the front an edge (7) facing the socket space.

A socket device for electrically contacting a corresponding plug device. The socket device has a first contact part having a first contact surface arranged radially between an outer first and inner second touch protection part, beyond which the first and second touch protection part axially protrude, a centrally arranged coupling unit, a receptacle region for receiving a corresponding third touch protection part of the plug device, and at least one insulating part, which is arranged extending in the radial direction on the first and/or second touch protection part and at a height above the first contact surface in such a way that the at least one insulating part at least partially overlaps with the first receptacle region but does not overlap with the first contact surface in a top view of the socket device.

A battery cell contacting device for a battery module having a plurality of battery cells electrically coupled to one another via a plurality of cell connectors has a rigid printed circuit board, which, in the region next to the plurality of cell connectors, is arranged over the battery cells and is connected to the plurality of cell connectors via a plurality of contact elements. For the purpose of making fitting easier and more reliable, each of the plurality of contact elements is formed from an electrically conductive wire. The wire, at the first end section of the contact element, is electrically conductively connected to the printed circuit board and, at the opposite, second end section of the contact element, can be electrically conductively connected to the respective cell connector and/or is coupled to a sensor element which can be brought into contact with the respective cell connector.
