Electronic control device for use in vehicles

An electronic control device for use in a vehicle, comprising a metallic housing for accommodating a printed circuit board of the control device, said housing having a wall with at least one internal rail, said internal rail forming an elongate channel which widens internally of said rail, said device further comprising at least one fastening member, said fastening member being a stud having a head portion which can be engaged in a form-fitting manner with said internally widened channel and having a pin portion which is connected to said printed circuit board, said printed circuit board accommodating a power semiconductor thermally connected to said housing wall by means of said fastening member.

An electronic control device for use in a vehicle, said electronic control device comprising a metallic housing for accommodation of electronic components of said control device, said metallic housing having a wall with at least one internal rail, said internal rail forming an elongate channel which widens internally of said rail, said electronic control device further comprising at least one non-threaded fastening member, said fastening member having a head portion inserted and retained in said elongate channel and having a pin portion connected to one of said electronic components by pressing said pin portion into an opening in said one of said electronic components, said housing wall being embossed from outside of said housing to prevent movement of said fastening member along said rail.

An electronic control device for use in a vehicle, comprising a metallic housing for accommodation of electronic components of the control device, said housing having a wall with at least one internal rail, said internal rail forming an elongate channel which widens internally of said rail, and further comprising at least one fastening member, said fastening member having a head portion inserted and retained in said channel and having a pin portion connected to one of said electronic components, said housing having a pair of parallel side walls and mounting brackets which are externally attached to said side walls, at least one of said mounting brackets having a length which is greater than that of said corresponding side wall and a bottom web, said bottom web extending over the whole length of the mounting bracket and extending under said housing wall and having an end which projects laterally from said housing wall.

An electronic control device for use in a vehicle, comprising a metallic housing for accommodating of electronic components of the control device, said housing having a wall with at least one internal rail, said internal rail forming an elongate channel which widens internally of said rail, and further comprising at least one fastening member, said fastening member having a head portion inserted and retained in said channel and having a pin portion connected to one of said electronic components, said one electronic component comprising a printed circuit board, said printed circuit board accommodating a power semiconductor device having a cooling vane, said cooling vane being connected to said housing by means of said fastening member, the heat being generated by the power semiconductor being thereby dissipated by said fastening member to said metallic housing.
