Abstract: An electrical plug connector (10) including a housing (12); at least one input-side contact (14, 16, 18); at least one output-side contact (20, 22, 24); and an electrical circuit (30) arranged inside the housing (12). The electrical circuit (30) has a sensor device (32), a control device (34) and a communication interface (38). The sensor device (32) is designed to detect an electrical operating parameter; and the control device (34) is designed to generate output data on the basis of the electrical operating parameter and to output said data by a communication interface (38). A method for operating a system having an electrical plug connector (10) is provided in which the plug connector (10) includes a sensor device (32) for detecting an electrical operating parameter.

Abstract: An electrical plug connector (10) having contacts (30) on the input side and a housing (20), within which electrical lines (40) and an electrical switch with at least one sensor device (84) and a control device (82) are connected to the contacts (30). The sensor device (84) and the control device (82) are arranged on a common carrier body (70). The carrier body is formed as a circuit carrier, which is made from plastic by injection-molding, on which metallic conductor tracks (80) are applied. This allows simple integration of sensor and monitoring tasks into conventional plug connectors.

Abstract: A circuit board with a connector connection for the direct contacting with a connector, wherein the connector connection is formed on the front side of the circuit board with a contact pin that is arranged centrally in a blind hole while forming a circular ring-shaped cylindrical insertion space and that has an inner hole with a first contact zone of an inner conductor for contacting an inner conductor of the connector. A second contact zone of an outer conductor is arranged in the insertion space for contacting an outer conductor of the connector.
