Embodiment Construction

[0026] figure 1 Seen in section, a transmission control module 1 of a motor vehicle is shown, as installed in the transmission interior of, for example, an automatic transmission. The transmission interior is filled with aggressive transmission oil. The transmission control module 1 comprises an electronics module 2 with an electrical circuit 3 and at least one sensor 4 as well as at least one plug-in connector 5 . The plug-in connector 5 serves to transmit control signals to the electronics module 2 or from the electronics module to the outside of the transmission with the transmission wall 6 . Furthermore, the transmission control module 1 comprises a lead frame 7 for the electrical conductor connection between the electronics module 2 , the at least one sensor 4 and the at least one plug-in connector 5 . The lead frame 7 is a lead frame 7 designed and tailored accordingly based on the type of special transmission interior space. The lead frame 7 is mounted on the housing...

Abstract

The invention relates to a transmission control module (1) of a motor vehicle, comprising an electronic module (2) with an electrical circuit (3), a lead frame (7) and at least one sensor (4) to be mounted inside a transmission, and at least one plug-in connector (5) for establishing an electrical connection between the inside and the outside of a transmission, the lead frame (7) being electroconductively connected to the electronic module (2), the at least one sensor (4) and the at least one plug-in connector (5). The transmission control module (1) according to the invention is characterised in that it (1) can be mounted inside a transmission and the lead frame (7) is made of an aluminium alloy.

Description

technical field [0001] The invention relates to a transmission control module for a motor vehicle. Background technique [0002] An electronic control unit is used for controlling the automatic transmission, which is arranged within the transmission housing. For laying the electrical conductors, for example, flexible printed circuit boards or injection-molded lead frames are used. The electronic control unit is an integrated transmission control module and usually has an electronic module ("transmission control unit: transmission control unit", TCU) with electronic circuits, at least one sensor, at least one plug-in for connection to the vehicle cable harness Type connector and electrical interface for operating the actuator. Lead frames are used as conductor circuit lead frames for electrical contact controllers. It is known to use injection-molded lead frames for electrical conductor routing. The conductor track leadframe or wire leadframe is made of a copper alloy in ...
