Electrical contact assembly

An electrical contact arrangement having a first contact element and a second contact element, which are arranged electrically insulated from one another by means of at least one insulation element or an electrically insulating coating formed on a surface of at least one of the contact elements and

• a through hole being formed in each of the first and second contact elements, into which through hole a first mandrel and a second mandrel can be inserted and
• a groove-shaped recess each being formed on the first contact element and/or the first mandrel and an inner shell of the second contact element and/or an outer shell of the second mandrel, in each of which at least one ring-shaped spring element is located in a form-fitting manner and
• the at least one spring-shaped spring element is formed from an electrically conductive and elastically deformable material and its inner and outer dimensions are geometrically designed and dimensioned such that the radially outward and/or the radially inward-facing wall act against the surface of a mandrel and the surface of the first and second contact element in the region of the groove-shaped recess with the application of compressive force when the first and second mandrels are inserted into the through holes to produce an electrically conductive connection and
• the first electrical contact element or the first mandrel is connected to one pole of an electrical voltage source and the second electrical contact element or the second mandrel is connected to an another pole of the electrical voltage source.
