Abstract
An electrical contact assembly between two conducting elements disposed face to face comprises wedge-shaped graphite inserts (26) located in similarly shaped grooves (22) in one of the faces (20). One end of each insert (26) lies short of the end of the groove (22) and the other end is proud of the face (20), so as to make good electrical contact with the other face (34) when the two faces (20,34) are pressed together. The invention achieves good electrical contact and conduction of current in applications where this has proved difficult in the past. Particular examples are clamps for graphite electrodes and connections to steel billets used as electrodes in an electro slag refining process.
