INTERFACE MODULE

The present invention relates to an improved interface module providing a simple but effective way of connecting a male contact element within the interface module, which interface module shall avoid fretting corrosion even if less noble materials are provided on contact surfaces making electric contact between a contact path on the male contact element and a contact element making electrical contact with said contact path. As a solution to the above object, the present invention proposes an interface module comprising a base (14) defining a planar sliding surface (56) for a male contact element (50), a connector housing (2) made of an electrically insolating material, wherein the connector housing (2) is movably received in a receptacle (54) of the base (14), wherein the connector housing (2) receives at least one contact element (4), said contact element (4) being arranged above the sliding surface (56) and provided with a contact leg (30) projecting below a planar supporting surface (78) for the male contact element (50) defined by the connector housing (2) in a preassembled state, and wherein the connector housing (2) has an insertion opening (74) adapted to receive the male contact element (50), and further comprising a spring element (6) arranged opposite to the at least one contact element (4) in a direction perpendicular to the sliding surface (56) and adapted to a elastically abut against an underside of the male contact element (50) in an assembled state of the male contact element (50), wherein, in said assembled state, the male contact element (50) is received within the insertion opening (74) of the connector housing (2) and the at least one contact leg (30) of the contact element (4) abuts a contact surface (46) on an upside (48) of the male contact element (50).
