Patent ID: 8784121

Claim:
A control device for a motor vehicle, with a housing ( 10 , 10 ′, 10 ″) and at least one circuit carrier ( 20 , 20 ′, 20 ″), which is arranged in an interior space of the housing ( 10 , 10 ′, 10 ″) and has at least one first contact element ( 22 , 22 ″) which, adjacent at least one housing wall ( 11 , 11 ′, 11 ″), produces an electric connection to at least one second contact element ( 17 , 17 ″) of a plug receptacle ( 50 , 50 ″), wherein the at least one second contact element ( 17 , 17 ″) is guided through the at least one housing wall ( 11 , 11 ′, 11 ″) and is a contact spring which bears against the at least one first contact element ( 22 , 22 ″) by means of spring force, characterized in that the at least one housing wall ( 11 , 11 ′, 11 ″) has receiving means ( 11 . 1 , 11 . 1 ′, 11 . 1 ″) to receive a first of the at least one circuit carrier ( 20 , 20 ′, 20 ″), the first circuit carrier ( 20 , 20 ′, 20 ″) being guided by guide means ( 13 . 1 , 14 . 1 ) formed in the housing ( 10 , 10 ′, 10 ″), at least one of the guide means ( 13 . 1 , 14 . 1 ) and the receiving means ( 11 . 1 , 11 . 1 ′, 11 . 1 ″) forming a mechanical stop ( 19 , 19 ′, 19 ″) for the first circuit carrier ( 20 , 20 ′, 20 ″), wherein the position of the first circuit carrier ( 20 , 20 ′, 20 ″) in the mechanical stop ( 19 , 19 ′, 19 ″) is fixed with a sufficiently small tolerance such that the electric connection is positioned between the at least one first contact element ( 22 , 22 ″) of the first circuit carrier ( 20 , 20 ′, 20 ″) and the corresponding at least one second contact element ( 17 , 17 ″) of the plug receptacle ( 50 , 50 ″); wherein a second of the at least one circuit carrier ( 30 , 30 ″) is guided in the guide means ( 13 . 1 , 14 . 1 ) adjacent the first circuit carrier ( 20 , 20 ′, 20 ″), at least one third contact element ( 37 , 37 ″), which is a contact spring, being arranged on the second circuit carrier ( 30 , 30 ″) and producing an electric connection to at least one corresponding fourth contact element ( 24 , 24 ″) of the first circuit carrier ( 20 , 20 ′, 20 ″); and wherein at least one of the at least one first contact element ( 22 , 22 ″) and the at least one fourth contact element ( 24 , 24 ″) is a contact surface which is arranged on one of a surface of the first circuit carrier ( 20 , 20 ′) and an outer edge of the first circuit carrier ( 20 ″) that is opposite the at least one housing wall ( 11 , 11 ′, 11 ″) and the at least one first contact element ( 22 , 22 ″).
