Embodiment Construction

[0018] FIG. 1 schematically shows the interior of a housing 1 of a control device, which is used, for example, in a motor vehicle as an electronic ignition control device for an internal combustion engine. The housing 1 comprises a not shown annular side wall and a bottom portion with a substrate 2 glued thereon. The housing 1 can be closed with a cover, not shown, so that the substrate 2 is housed protectively in the housing. Preferably, the substrate 2 is an LTCC substrate provided with microhybrid circuits. However, it can also be another ceramic substrate or a printed circuit board substrate. On the LTCC substrate is provided an electronic control circuit, which has components 17, such as resistors, capacitors, IC's or microprocessors, and conductor lines connected to them, but not shown in Figure 1, which lines are known as The means are made with conductive solder on or in the LTCC substrate. On the upper side of the substrate 2 are provided connection areas 12 , 13 f...

Abstract

An electronic control unit having a housing, a substrate, particularly a hybrid, arranged in the housing and having an electronic control circuit. The electronic control unit also includes at least one device plug secured to the housing having contact elements that are electrically conductively connected to the control circuit of the substrate. A second substrate is arranged in the housing, spatially separated from the first substrate. At least one power component disposed in the housing and, electrically connected to the control circuit on the first substrate. One connecting printed circuit trace disposed in housing and conductively connected to the power component. The connecting printed circuit trace are conductively connected to a contact element, conducting power currents, of the device plug. Using the arrangement, in the event of a large number of contact elements in a device plug, the electrical connecting of the contact elements to the substrate can be simplified. Moreover, the printed circuit trace layout is simplified, an improvement in the EMC protection is achieved, and the dissipation of heat generated by the power component is improved.

Description

technical field [0001] The invention relates to an electronic control device, which has a housing; a substrate with an electronic control circuit arranged in the housing; and at least one device plug with contacts fixed on the housing, and the control of the contacts and the substrate The circuits form electrical connections. Background technique [0002] From DE 36 24 845 C2 a control device for electric ignition systems is known, which has a device plug fastened on the control device housing, which plug has a plurality of contact pieces. The contacts of the device plugs which insulate through the shell are connected with the control circuit on the hybrid circuit board through connecting wires inside the shell, and form a pin outside the shell, which can be connected with the cable harness socket of the corresponding structure. Corresponding contacts are connected. Such a control device is usually installed in the engine compartment of a motor vehicle. An electrical conn...
