Abstract:
An intercoupling component is provided which permits reliable, non-permanent electrical connection between a first substrate and a second substrate. The intercoupling component includes a socket terminal having a first end, and a second end opposed to the first end. An axial hole extends inward from the second end, and an electrically conductive core member is disposed within the axial hole. The core member is formed of a different material than the socket terminal body, and is sized and shaped to obstruct the hole. In addition, the first end of the socket terminal is configured to receive a pin terminal, and the second end of the socket terminal is configured to be received within a hole in a printed circuit board.
Abstract:
A single element electrical connector includes a single conductive contact element formed into a cage structure having a wire insert end and a wire contact end along a longitudinal centerline axis of the connector. The cage structure defines an upper pick-up surface having a surface area suitable for placement of a suction nozzle of a vacuum transfer device, as well as a pair of contact tines biased towards the centerline axis to define a contact pinch point for an exposed core of a wire inserted into the connector. A contact surface is defined by a member of the cage structure for electrical mating contact with a respective contact element on a component on which the connector is mounted.

Abstract:
An intercoupling component is provided which permits reliable, non-permanent electrical connection between a first substrate and a second substrate. The intercoupling component includes an electrically conductive terminal including a first end and a second end opposed to the first end. The first and second ends are configured to receive a solder ball. An axial hole extends inward from the first end of the terminal, and an electrically conductive core member is disposed within the hole. The core member is sized and shaped to obstruct the hole. In addition, at least an outer surface of the core member includes a first material and at least an outer surface of the body includes a second material, the first material having greater solderability than the second material.

Disclosed are hydraulic/electronic control units (1, 2) for an electronic brake control system. A hydraulic/electronic control unit of current ABS/TCS/ESP systems essentially includes a central hydraulic block (6) and an electronic control unit (1) including control electronics on a control circuit board (4). The circuit board (4) is structured in such a way that it is insulated completely towards the outside on at least one first side (28) and includes an essentially smooth surface. Thus it is possible to use the hydraulic block (6) for cooling the circuit board (4).

A printed circuit board assembly for coupling a plurality of surge protectors to multi-line communication cables includes a multi-layer printed circuit board, to which has been mounted at least two cable connectors, having multiple female sockets for receiving standard surge protector modules. The multi-layer printed circuit board includes traces on multiple layers in a manner that a unique signal path exists between each lead in each connector and a predetermined one of the plurality of sockets for receiving surge protector modules. The traces having a width and a copper content sufficient to carry large current surges from induced power signals, by way of example, from a lightning strike, without breaking down.
Abstract:
A mother board mounts a memory module via a plug-socket coupling, wherein the edge of the memory module has a plug member mounted on a socket member of the mother board. The mother board has a plurality of abutment members abutting the edge surface of the bottom edge of the memory module for which the plug is formed. The abutment members act as ground terminals for connecting the ground layer of the memory module to the ground layer of the mother board, and also act as heat radiation members.
