Circuit board with a plug connection

A control unit with a circuit board that has a first plug element, which is configured to be joined with a second plug element to form a plug connection, wherein the circuit board has a first side populated with first components and containing conductor paths, and a second side, and wherein the first plug element is securely mechanically connected to the first side of the circuit board in a contact and attachment region of the first side and contains first electrical contacts that are electrically conductively connected to at least one of the first components through metallic structures running on or in the circuit board, and wherein the first plug element is securely mechanically connected to the second plug element, wherein electrical contacts in the first plug element configured to produce a plug connection that is disposed entirely within a first interior region of the control unit delimited by the first side of the circuit board, which is separated by the circuit board from a second interior region of the control unit delimited by the second side, and in that the second side has a contact and attachment region lying opposite the contact and attachment region on the first side, in which second electrical components are located and/or in which conductor paths run, the control unit has a housing that delimits an interior space of the control unit, and wherein the circuit board is placed in the housing such that the circuit board divides the interior space into a first interior region delimited by the first side and a second interior region delimited by the second side, wherein solder pads are located on the first side of the circuit board, to which first contacts are soldered, wherein the first contacts are SMD solder contacts that do not pass through the circuit board, and in that the control unit contains an electrically insulating pin mount in which segments of the first contacts are embedded, and wherein the electrically insulating pin mount bears on the inner surface of the control unit housing.
