A bus bar connector system and an electrical distribution center suitable for use in a motor vehicle including such a bus bar connection system is presented. The bus bar connector system includes a first bus bar, a second bus bar, and a spring clip configured to apply a contact force to the first and second bus bars effective to bring at least a portion the first and second bus bars into intimate contact with one another. The spring clip may comprise two longitudinal spring arms each extending from a lateral spring base interconnecting the spring arms. These spring arms are angled toward one another and end portions of the spring arms may be angled away from one another, thereby forming an hourglass or X-shaped spring clip. The end portions of the spring arms may be configured to retain the spring clip within a slot defined by a connector housing.

A holder for supporting electrified inserts that may vary in width, comprises a base having a groove into which the insert can be placed. Two or more gaskets can be positioned in the groove with each gasket including a resilient section adapted to engage the insert so as to retain the insert securely in place within the groove. Each of the gaskets also includes an electrical conductor, such as an electrical wire, which may be embedded in the gasket, in a position where it makes electrical contact with the electrical terminals on the insert.

An electrical terminal assembly is provided for use in a low-profile electrical raceway or the like. The terminal assembly includes first and second conductive bodies and an insulator disposed between them. The first body has at least two branches including respective electrical terminals extending outwardly from a main or central portion, with the terminals positioned in a terminal plane. The second body also has at least two branches including respective electrical terminals extending outwardly from a main or central portion, with the terminals positioned in the same terminal plane as the terminals of the first body. The terminals of the second body are positioned next to respective terminals of the first body. The central portions of the first and second bodies are stacked atop one another and therefore lie in different planes, at least one of which is different from the terminal plane.

A battery distribution unit (BDU) for holding a first electronic device having a first blade terminal extending therefrom and a second electronic device having a second blade terminal extending therefrom includes a BDU housing, a strip busbar received in the BDU housing, and first and second cross terminals received in the BDU housing. The first cross terminal receives the strip busbar at a first end thereof and is configured to receive the first blade terminal at a second end thereof. The second cross terminal receives the strip busbar at a first end thereof and is configured to receive the second blade terminal at a second end thereof.

A holding frame for a plug-type connector is intended to have good heat resistance and a high level of mechanical robustness and, when installed in a metallic plug-type connector housing, enable protective grounding while at the same time being convenient to use, in particular during the replacement of individual modules. To this end, it is proposed to manufacture the holding frame at least partially from spring-elastic sheet metal. For this purpose, the holding frame can have a basic portion and a deformation portion, which are formed from different materials. The basic portion is used for fixing an accommodated module in a plane. The deformation portion can assume an insertion state and a holding state, wherein the insertion state permits insertion of at least one module into the holding frame in a direction transverse to the plane and an accommodated module is fixed in the holding state.

A first electrical connection box includes a housing, a holder (50) that is provided inside the housing and holds an electrical component, and a terminal block (60) attached to the holder (50). The terminal block (60) includes a terminal support base (61) attached to the holder (50), and a busbar (62) supported on the terminal support base (61). The busbar (62) includes a planar first connection surface (84) to which a first wire (21) is to be electrically connected, and a planar second connection surface (86) to which a second wire (22) is to be electrically connected, the second wire (22) being different from the first wire (21). When a direction perpendicular to the first connection surface (84) is defined as a first direction (X11), the second connection surface (86) is perpendicular to a second direction (X12) that intersects with the first direction (X11).

A terminal block includes a bus bar, a housing provided with an insertion space portion into which a second connection portion of the bus bar is inserted along an axial direction, a packing inserted into the insertion space portion together with the second connection portion and sealing an annular space between an outer surface of the second connection portion and an inner surface of the insertion space portion, and a packing holder provided with a bus bar insertion portion into which the second connection portion is inserted along the axial direction, and is inserted into the insertion space portion in a state where the second connection portion is inserted into the bus bar insertion portion and the packing is supported in the axial direction, in which the bus bar insertion portion is configured to include a first gap for allowing deformation of the second connection portion.

A bus bar assembly includes multiple bus bars, multiple insulating holders, and a housing. Each of the insulating holders is configured to be mounted to one of the bus bars. Each of the insulating holders includes multiple ribs positioned within an interior cavity of the corresponding insulating holder, and the ribs maintain a desired air gap between each insulating holder and the corresponding bus bar mounted in the insulating holder. The housing is configured to receive each of the bus bars and the corresponding insulating holder.

An electrical connection unit includes a first bus bar, a second bus bar, and a first heat transfer member thermally connecting the first bus bar to the second bus bar.

A bus bar includes a plate-shaped bus bar body provided with a plurality of connection portions electrically connected to bus bars as connection partners being provided as connection portions, a first protrusion provided to protrude from one side plate face of the bus bar body, and a second protrusion provided to protrude from the other side plate face of the bus bar body. The bus bar body has a recess, and in a normal attachment posture in which the bus bar body is attached to an electrical connection box as an installation target having a rib as a projection, the recess and the rib are engaged.
