  • a method step may be to fix the socket 160 to the edge connector 1 15 or the control unit 100, z. B. by means of screws, gluing, clamps.
  • Another method step may be to mount and fix the control system or the mechatronics on or in the hydraulic control or switching plate or on the gear housing 280.
  • cables or connecting lines 170 can be laid, fixed or secured and the further transmission control units, such as connectors, sensors and valves, can be positioned and fastened.
  • the electronics or controller 100 may be provided as a terminated and tested package.
  • System modules can be optimally assembled, eg. As valve assembly, connector assembly or sensor assembly, and electrically connected at the appropriate time in the manufacturing process and possibly mechanically. This results in a saving of a separate, to be attached to the circuit board 1 10 mating connector for connection with the other transmission control elements.
  • no additional mechanical parts such as caps are necessary when the edge connector 1 15 has structurally integrated the chip protection in the form of the potting compound or the socket 160 covers the pin 1 15 in the additional function as chip protection.
  • An attachment for example, by screwing the socket 160, for example, on the front side of the control unit 100, for example on the lower part or upper part of the housing 120th or the circuit board, provides a robust connection between the controller 100 and the interconnect system 150.
  • simple processes such as mating may be used, allowing for low cost manufacturing.

Abstract

L'invention concerne un appareil de commande (100) pour une transmission d'un véhicule. Ledit appareil de commande présente un boîtier (120) et une carte de circuits (110) comportant une zone de composants (116) prévue pour des composants électriques (118) ainsi qu'une zone de mise en contact (112) comportant une pluralité de contacts électriques (114) pour raccorder d'autres éléments de commande de transmission. Ledit appareil de commande (100) se caractérise en ce que la zone de composants (116) de la carte de circuits (110) se situe à l'intérieur du boîtier (120), la zone de mise en contact (112) de la carte de circuits (110) se situant quant à elle en dehors dudit boîtier (120). A cet effet, la zone de mise en contact (112) de la carte de circuits (110) forme un connecteur marginal (115) pour une douille femelle (160) de connecteur.
