Abstract: An arrangement for a motor vehicle for central connection of electrical components, the arrangement comprises a housing, a plurality of supply circuits and control circuits, a plurality of circuit straps punched out of metal sheets and printed circuit boards, the supply circuits and the control circuits being formed so that the supply circuits are formed exclusively from the punched circuit straps and the control circuits are formed exclusively from the printed circuit boards, the printed circuit boards with the punched circuit straps and their intermediate insulations being assembled in a plurality of layers in a substantially identical surface configuration to form a printed circuit pack.

Abstract: The electromagnetic relay, particularly an armature relay, includes a ferromagnetic yoke with a yoke wall, and a ferromagnetic coil core, which is mounted by inserting a neck portion thereof in a hole in the yoke wall, for example in a press fit. To provide a connection between the coil core and the yoke which is more permanent, a support for the coil core is provided on the yoke wall which includes a projection on the inner surface of the yoke wall and a recess in an outer surface of the yoke wall (4) on an opposing side from the projection on the inner surface (27). The projection (28) extends from the inner surface of the yoke wall toward a shoulder (32) of the coil core (7). The neck portion (6) of the coil core (7) extends into the recess (29) and a rivet (39) for fastening the neck portion (6) in the recess (29) of the support (26). The recess (29) and the projection (28) are approximately equal. A method of making the electromagnetic relay is also described.

Abstract: A central electric unit detachably interconnects various electric constructions parts and equipment such as wiring harnesses, connectors, fuses and switching devices for electric consuming circuits in a motor vehicle. The unit includes a housing structure provided with connecting plugs and sockets and enclosing a microcomputer which unifies controlling functions for all electric consumers. The microcomputer is separated from and operates independently of the exchangeable switching devices.

Abstract: A central unit for interconnecting consumer circuits in a motor vehicle includes a pack of superposed insulating boards each supporting flat conductors. The conductors on the uppermost board are connected to a plurality of connector sockets for receiving connector plugs of the electric components. The flat conductors on respective insulating boards are electrically connected to flat connector pins projecting laterally from opposite sides of the pack. Two bridging connector plates are arranged parallel to the opposite sides of the pack and support bridging conductors for contacting different connector pins at different levels of the pack so as to provide a desired interconnection of the connector sockets.
