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.

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 housing cap for closing an opening of a housing part includes a cover section covering the opening, a stop projecting away from the cover section, and a fastening element affixing the housing cap to the opening.

The present disclosure discloses an electric connection assembly having a support and a connector; the support comprises a support body; the support body is provided with a mounting groove and a limiting protrusion; at least part of the connector is arranged within the mounting groove; and the limiting protrusion can cooperate with the connector so as to prevent the connector from withdrawing from the mounting groove. Compared with the prior art, the electric connection assembly is simple in overall structure and convenient to assemble. In the electric connection assembly, the stability of the integral assembly of the connector and the support can be enhanced by arranging the corresponding limiting protrusions on the support. Particularly, compared with the support and the connector which are integrally formed by embedded injection molding, the electric connection assembly can avoid the problems of fixed mounting position, inflexibility and the like of the connector due to reasons such as tolerance and the like.

A battery terminal includes a terminal main body and a protector to be mounted to the terminal main body, wherein the terminal main body includes an operating section for clamping and tightening the battery post, and the protector includes a movable section provided with a contact section to be brought into contact with the upper surface of the battery main body, and a displacement section to be freely displaced between a covering position for covering the operating section and a retracted position with an external force applied on the contact section, wherein in the retracted position, the displacement section is retracted from the covering position, and wherein the displacement section is displaced to the retracted position by pressing the contact section against the upper surface of the battery main body so that the access to the operating section is allowed.

A terminal cover includes a cover body equipped with a curved portion and a base portion. The curved portion has formed therein a pair of claws diametrically opposed to each other. The claws are arranged at an interval away from each other. The interval is selected to be smaller than the width of the terminal and increased by elastic deformation of the cover body arising from installation of a terminal in the terminal cover, so that the claws retain the terminal. This structure enables the terminal cover to be simple and small-sized and facilitates installation of the terminal in the terminal cover without being scraped by the terminal when inserted into the terminal cover.

A battery terminal connector includes a body portion with a first yoke and a second yoke extending forwardly of the body portion to form a terminal receiver hole. A power fastener extends from a rearward end of the body portion to receive one or more of an adapter, a primary cable adapter, and/or an auxiliary cable adapter. Each of the adapter, the primary cable adapter, and/or the auxiliary cable adapter extends rearwardly of the body portion. The adapter has at least a first aperture configured to be coupled to the power fastener and a second aperture configured to be coupled to the auxiliary cable adapter. The auxiliary cable adapter may be coupled to the second aperture with an auxiliary fastener. A cover is coupled over the battery terminal connector.

A battery connection apparatus for a vehicle including a cable terminal includes a terminal connection part provided in a tubular shape to be fitted to a circumference of a battery terminal protruding from a battery of the vehicle, the terminal connection part having an opening formed in a shape of being gradually widened between opposite ends thereof in a circumferential direction and male threads formed on an outer circumference thereof, and a fixing member provided to fix the battery terminal connection part in a state in which the battery terminal connection part is connected to the battery terminal, the fixing member having female threads, that correspond to the male threads, formed on an inner circumference thereof to be screwed to the outer circumference of the battery terminal connection part.

A connector assembly for electrically connecting poles of two adjacent battery cell. The connector assembly comprises an electrically conductive bus bar having a first connection area and a second connection area distal from each other, electrically conductive pole-mating components having a pole-mating face and a bar-mating face, and fastening components for attaching the electrically conductive bus bar and one of the pole-mating components to one of the poles of the two adjacent battery cells. The pole-mating faces of the pole-mating components are adapted for mating the poles the battery cells. The bar-mating faces of the pole-mating components are adapted for mating with the connection areas. The bar-mating faces and the connection areas have complementary concave/convex arched shape for optimizing contact surface over a range of relative positioning of the two adjacent battery cells.

A battery post terminal assembly includes a conductive band and a clamp mechanism. The conductive band includes a first free end and a second free end. The conductive band defines an aperture for receiving a battery post of a battery. The clamp mechanism includes a wedge member that defines a recess between a first surface and a second surface thereof. The recess has an open end and a closed end that is narrower than the open end. The first surface is convex. The first free end and the second free end are positioned in the recess. The first free end is movable along the first surface toward the closed end to be moved by the first surface toward the second free end to tighten the conductive band around the battery post.
