A battery module includes a pack section and a cover assembly. The pack section has an interconnect board, conductive channels, and battery cells extending through the interconnect board. Each battery cell includes electrode cell tabs joined to a corresponding conductive channel. The cover assembly is connectable to the pack section, and has conductive interconnect members, electrical fuses, and sense lines built into or integral with a cover plate. The interconnect members extend from the cover plate and form part of an electrical circuit between the conductive channels of the pack section and the fuses and sense lines of the cover plate when the cover assembly is connected to the pack section. An electrical system includes the battery module, a DC voltage bus, and at least one high-voltage component connected to the battery module via the DC voltage bus. The electrical system may be part of a motor vehicle.

An electrical connector and system for connecting to a terminal post. The electrical connector includes a housing body, a contact and a locking release member. The housing body includes a post receiving passage for receiving the terminal post therein. The contact is provided in the post receiving passage and is positioned about the circumference of the post receiving passage. The contact will make an electrical engagement with a terminal post inserted into the post receiving passage regardless of the orientation of the terminal post with respect to the contact. The electrical connector which prevents the improper mating of the connector to the post, prevents unwanted rotation of the connector, provides a visual indication that the proper connection is secured and provides a secondary lock to ensure that unwanted unmating of the connector does not occur.

Disclosed is a device where a male contact body can be inserted into the female contact body along an insertion direction and the male contact body has a cavity which reaches through the male contact body; and a spreading element, which is inserted into the cavity and which has cross-sections that taper along the longitudinal axis of the spreading element in the securing direction, wherein the spreading element can be converted from a released position into a tightened position along the securing direction such that the male contact body is spread apart, thus generating a contact pressure between the female contact and the male contact body. In the process, the cavity reaches through the entire male contact body and thus forms two openings on the male contact body. The inner face of the male contact body has a first latching element, and the outer face of the spreading element has a second latching element, the first latching element latching with the second latching element when the spreading element reaches the tightened position so that the spreading element is secured in the tightened position.

Provided is a plate spring fixing structure and the like which do not necessitate complex assembling processes and thus can reduce production cost and can be reduced in size, and which enable adjustment, during a production process, of the extent to which the plate spring is bent. A holding structure (1A) includes a first plate spring (12) that has: a fixed portion (12a) embedded in and fixed to a first molded resin part (11); and a spring portion (12b) which is not fixed and which has a spring property. The fixed portion (12a) has a face that is not in contact with the first molded resin part (11).

A battery terminal clamp has a body portion with an intermediate aperture for engaging a battery post. The clamp further includes a threaded rod extending upwardly relative to the body portion at an angle to the horizontal of between 45 and 60. A battery pull bar extends from one side wall to the opposite side wall of the body portion. A wedge-shaped element abuts one side wall of the body portion. Together with the battery pull bar, the wedge-shaped element alternately effects a reduction in, or increase in, the size of the intermediate aperture.

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 female terminal fitting (F) includes a rectangular tubular main body (10). The main body (10) has a rear base plate (14). Left and right side plates (15) are connected at substantially right angles to opposite left and right sides of the rear base plate (14). A main spring piece (20) is accommodated in the main body (10) and is configured to resiliently contact a tab (T) of a mating terminal (M) inserted into the main body (10). An auxiliary spring piece (23) is cantilevered from the rear base plate (14), is accommodated in the main body (10) and is configured to apply a resilient pressing force toward the tab (T) to the main spring piece (20). A reinforcing portion (28) is formed by striking a range from a base end part (23R) of the auxiliary spring piece 23 to the rear base plate (14).

Contacting apparatus for contacting an energy storage cell (1) comprising at least one printed circuit board (5) which is provided for discharging the electrical energy stored in the energy storage cell (1), wherein at least one electric pole of the energy storage cell (1) is pressed by a releasable mechanical connection (7) with a specific contact pressing force against an electrically conductive layer (5c) of the at least one printed circuit board (5) which is located on a front side of the at least one printed circuit board (5) facing the energy storage cell (1).

What is described is a battery terminal having a pole contact element which is designed to surround a pole of a rechargeable battery on a mounting plane; a first limb and a second limb which are each connected to the pole contact element, the spacing between the first and second limbs being reducible by application of force in order to fasten the pole contact element to the pole, and a tensioning arrangement which couples the two limbs to one another, said tensioning arrangement having a tensioning screw which can be actuated so as to apply force to the two limbs and which is oriented along a tensioning direction which is tilted with respect to the mounting plane. In this case, the tensioning arrangement comprises a first clamping piece which can be positioned on the first limb and a second clamping piece which can be positioned on the second limb, wherein the tensioning screw is passed through a first screw receptacle formed in the first clamping piece and a second screw receptacle formed in the second clamping piece, said first and second screw receptacles being aligned with one another along the tensioning direction.
