  • Patent number: 6304455
    Abstract: An arrangement includes a supporting plate, at least one substrate applied thereon for electrical and/or electronic components and a plug-in part. The plug-in part includes a plurality of connector pins which are embedded in insulating material, whose first ends are provided for the connection to external plug-in devices and whose second ends are electrically connected to the substrate via bonding wires. In order to reduce the dimensions of the raster of the connector pins and to achieve a small, compact design of the arrangement, the individual connector pins are manufactured as stamped-out parts whose second ends, in each case, have end faces manufactured in the stamping process and running roughly parallel to the substrate, and the bonding wires are welded directly to the stamped-out end faces of the connector pins. In addition, there is a method for manufacturing the arrangement.

  • Patent number: 6068491
    Abstract: A connector arrangement of a control system with a controller in a motor vehicle is designed so that it can be manufactured advantageously and is reliable in operation.To do so, the connector arrangement and the respective controller are designed so that several separate connector sockets with externally accessible contact elements are arranged on the controller, which is mounted on the vehicle's internal combustion engine as a surface-mounted controller, some of the contact elements being designed as high-current contact elements which are connected directly to one another through busbars running inside the controller.The respective mating connectors can be connected to the connector sockets, the mating connectors being electrically connected to components of the vehicle over cable harnesses or cable segments, where a first mating connector connected to cable segments is composed of partial mating connectors which can be handled independently of one another.

  • Patent number: 6045411
    Abstract: An electrical device that is operationally reliable even under increased mechanical stresses, and which is cost-effective to manufacture. The device includes a recess on a housing for accommodating a plug-connector housing. The plug-connector housing is formed in that contact elements and a retaining element of the housing extending into the recess, as well as the segments of the housing bordering the recess, are introduced as insertion parts into a plastic injection molding die, and after the plastic injection process and the removal of the molding die, a plug-connector housing provided with contact elements is formed, fixedly positioned as an integral part on the housing of the device. The electrical device is preferably used in motor vehicles.

  • Patent number: 5771859
    Abstract: The invention is directed to a method for controlling the idle of an internal combustion engine having an intake channel for conducting air to the engine. The method utilizes sensors for generating signals characterizing the operating state of the engine and for supplying the signals to a control apparatus. A tank-venting valve is provided through which air can be conducted into the intake channel when the tank-venting valve is open. Control quantities are computed in the control apparatus in dependence upon the signals for at least the following: the tank-venting valve, an idle adjuster device, a fuel metering device and an ignition device. The air supplied to the engine is controlled with the aid of the tank-venting valve. The invention is also directed to an arrangement for carrying out the method.

  • Patent number: 5711271
    Abstract: Electronic engine control systems have a plurality of individual components on the intake tube, some of them located relatively far from one another. For electrically connecting the individual components to the electronic control unit, relatively long electric connecting lines and a relatively large number of plug connections are therefore necessary. This invention sets forth a preassembled throttle apparatus which includes at least one throttle device, rotatably accommodated in a throttle valve support, and an idling adjuster in a housing; the throttle apparatus has a bypass conduit, which bypasses the throttle device and which can be varied by the idling adjuster, into which a regeneration valve can output fuel, the regeneration valve being triggerable by an electronic control unit that is also accommodated in the housing. The throttle apparatus of the invention is intended particularly for mixture-compressing internal combustion engines with externally supplied ignition.
