Connector with a spring member for electric direct contacting of a circuit board

The plug (1) has contact elements (7) arranged in contact carriers (5) for retaining a circuit board. Pressing spring devices (9) press the contact elements on contact surfaces of the board. The spring devices have power transmission regions (17) arranged vertical to a plug direction (11). The spring devices are arranged at the plug such that the spring devices convert force acting on the power transmission regions in the direction into contact normal force acting on the contact elements vertical to the direction. The spring devices provide spacer function. An independent claim is also included for a plug connection.
