A connector for terminating to a battery terminal post. The connector includes a post-engaging portion which has an opening for receiving the battery terminal post therein. The post-engaging portion is movable between an open position and a secured position. A retention insert is provided in the opening of the post-engaging portion. The insert has resiliently deformable projections which extend into the opening. With the battery terminal post inserted into the opening and the post-engaging portion moved to the secured position, the resiliently deformable projections of the insert engage and retain the battery terminal post in the opening to prevent unwanted movement of the connector relative to the battery terminal post.

An electric connection plug (5, 5, 5) for an electric cable (3) for use with an electric terminal (20, 21, 20, 21) of a battery module (2, 2). The plug includes a conductive fitting (51, 51, 51) engaged with a rotatable wheel (56, 56, 56) for selectively rotating the fitting to threadingly mechanically and electrically connect to plug to the battery terminal. The cable mechanically and electrically connects to the plug allowing rotation of the wheel and fitting without rotation of the cable while threadingly engaging and disengaging the plug to the battery terminal.

A plug-in connection includes a first and second coupling part. The first coupling part includes a first contact element, an electrical cable, an insulation sleeve, and a first housing. The first contact element includes a base region and an outer region with an edge region, an external shell surface, and a slot. The electrical cable includes an electrical conductor, a connection region, and an insulation for the electrical conductor. The insulation sleeve surrounds the outer region and includes an external and internal shell surface. The first housing surrounds the base region, the insulation sleeve's external shell surface, and the connection region. The second coupling part includes a second contact element with an external shell surface over which the first contact element's outer region is slidable, and a second housing which encloses the second contact element and together therewith forms an annular space into which the first housing is insertable.

Locking assemblies are provided for connecting to a stranded element. The locking assemblies include a housing with a receiving bore, locking bore, and aperture. The stranded element enters the housing through the receiving bore. A drive shaft can advance a locking element in the locking bore such that the locking element contacts the stranded element to apply a force to secure the stranded element to the locking assembly. Ends of the stranded element can be pushed by the locking element out of the housing through the aperture. The locking assemblies can be used for mechanical and/or electrical connections. Examples of stranded elements include electrical wires, mechanical stranded cables, rope, and other multi-strand materials.

A connector includes a male connector, a female connector and a rotating clamping structure. The male connector includes a first housing with multiple channels, the female connector includes a second housing with at least one positioning slot. The rotating clamping structure includes a third housing, multiple first positioning pins, multiple stoppers and multiple second positioning pins. The rotating clamping structure can realize the locking or separation of the male connector and the female connector.

A connection structure for an external connection bus bar configured to connect the external connection bus bar to an external connection electrode terminal of a power storage element stack including power storage elements including electrode terminals. The connection structure includes: the external connection bus bar including one end part to be connected to the external connection electrode terminal; a receiving connector that houses the external connection bus bar and is fixed to the power storage element stack, and that includes a connector terminal to be connected to the external connection bus bar and to connect the external connection bus bar to an outside; and a fixing member that is provided to one end of the power storage element stack and fixes the receiving connector. The external connection bus bar includes a flexible part that is configured to expand and contract in a direction where the power storage elements are arranged.

The insulation sleeve surrounds the outer region and includes an external and internal shell surface. The first housing surrounds the base region, the insulation sleeve's external shell surface, and the connection region. The second coupling part includes a second contact element with an external shell surface over which the first contact element's outer region is slidable, and a second housing which encloses the second contact element and together therewith forms an annular space into which the first housing is insertable.

A battery clamp having a first inner metal battery clamp member having a handle portion and a clamp portion, a second inner metal battery clamp member having a handle portion and a clamp portion, a first outer insulating battery clamp member having a handle portion and a clamp portion connected to the first inner metal battery clamp, and a second outer insulating battery clamp member having a handle portion and a clamp portion connected to the second inner metal battery clamp. The first inner metal battery clamp member and/or the second inner metal battery clamp member having an inclined connection plate for connection with a battery cable, the inclined connect plate configured to allow a user to access the inclined access plate with a tool while avoiding interference with the handle portions of the battery clamp.

A battery clamp having a first inner metal battery clamp member having a handle portion and a clamp portion, a second inner metal battery clamp member having a handle portion and a clamp portion, a first outer insulating battery clamp member having a handle portion and a clamp portion connected to the first inner metal battery clamp, and a second outer insulating battery clamp member having a handle portion and a clamp portion connected to the second inner metal battery clamp. The first inner metal battery clamp member and/or the second inner metal battery clamp member having a battery cable connector configured to allow a user to access the battery cable connector with the user's fingers or a tool while avoiding interference with the handle portions of the battery clamp.

A method of forming an electrical terminal is presented herein. The method includes the step of stamping an electrical terminal preform from a sheet of metal. The electrical terminal preform having a base plate, a plurality of contact arms radially extending from the base plate, a wire attachment feature radially extending from the base plate, and a carrier strip. The base plate defines crimp wings. The method also includes the step of bending each of the plurality of contact arms to form a socket configured to receive a mating electrical terminal.
