The invention relates to a control device (1) for a motor vehicle, comprising a housing (10) and at least one circuit carrier (20), which is arranged in an inner chamber of the housing (10) and comprises at least one first contact element (22) that establishes an electric connection to at least one second contact element (17) of a plug receptacle (50) on at least one housing wall (11), wherein the second contact element (17) is guided through the at least one housing wall (11) and is designed on the inside as a contact spring that rests against an associated first contact element (22) by spring force, and to a related method for mounting a control device for a motor vehicle. According to the invention, the at least one housing wall (11) comprises receiving means (11.1) for a first circuit carrier (20), wherein the first circuit carrier (20) is guided through guide means (13.1) designed in the housing (10), wherein the guide means (13.1) and/or the receiving means (11.1) form a mechanical stop (19) for the first circuit carrier (20) that is designed such that the position of the first circuit carrier (20) is fixed in the mechanical stop (19) with sufficiently small tolerance such that the electric connection between the at least one first contact element (22) of the first circuit carrier (20) and the corresponding second contact element (17) designed as a contact spring is established in the plug receptacle (50).
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″);
A method for mounting a control device for a motor vehicle, which has 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 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 a first of the at least one circuit carrier (20, 20′, 20″), guided by guide means (13.1, 14.1) formed in the housing (10, 10′, 10″), is pushed into a first housing part (10.1) as far as a mechanical stop (19, 19′, 19″), the mechanical stop (19, 19′, 19″) for the first circuit carrier (20, 20′, 20″) being formed by at least one of receiving means (11.1, 11.1′, 11.1″) in the at least one housing wall (11, 11′, 11″) and the guide means (13.1, 14.1), the position of the first circuit carrier (20, 20′, 20″) in the mechanical stop (19, 19′, 19″) being fixed with a sufficiently small tolerance such that the electric connection is positioned between the at least one first contact element (22, 22″) and the corresponding at least one second contact element (17, 17″);
