Embodiment Construction

[0038] figure 1 A transmission control module 10 is shown that includes a circuit board 12 and an electronic assembly 14 thereon. Further components of the control module 10 , such as, for example, power connections 16 , further connections 18 , plug strips 20 , pressure sensors 22 , etc., can also be attached to the printed circuit board 12 .

[0039] The electronic assembly 14 is surrounded by a barrier 24 which extends partly at the edge of the circuit board 12 and which together with the circuit board 12 forms a recess in which the electronic assembly 14 is embedded in casting compound 26 .

[0040] if available in figure 1 As can be seen in the figure, the electronic component 14 is completely surrounded by the potting compound 26 . Furthermore, conductors protrude from potting compound 26 and are connected to connections 16 , 18 , 20 and to sensor 22 .

[0041] figure 2 The circuit board 12 is shown with the chip guard 30 before being inserted into an opening 32 in...

Abstract

The invention relates to a control module for a vehicle, said control module comprising: a circuit board having electronic components for controlling at least one actuator; a barrier surrounding the electronic assembly; a potting material into which the electronic component is embedded and which is cast inside the barrier; for the at least one actuator an electrical contact surface arranged on the back of the circuit board opposite the front with the barrier and the potting material; and an opening extending through the circuit board , the opening extends between the electrical contact surfaces; wherein a chip protection element is inserted into the opening, the chip protection element protruding on the back side of the circuit board and between the contact surfaces Partition walls are provided.

Description

technical field [0001] The invention relates to a control module for a vehicle. Background technique [0002] The electrical contacting of the actuator of the automatic transmission with its control module is often configured as a pair of spring contacts. Chips in the transmission oil can cause a short circuit between two spring contacts or associated contact surfaces or metal components that are too close together. In order to prevent this, the contact area on critical sides is surrounded by a protective wall, which is usually placed on the actuator. If the contact surface is directly on the surface of the circuit board, corresponding recesses must be provided in the circuit board, into which recesses the protective walls are inserted in order to achieve the necessary overlapping height and obtain a labyrinth effect. [0003] Recesses in the circuit board may be undesirable if electronic components are mounted on opposite sides of the circuit board using the so-called ba...
