Abstract
An electric contact arrangement for wire coils of stators of electric machines, particularly stator coils of electric motors, includes an annular support member of electrically insulating material stationarily abutting one end of the stator, pin-shaped projections on the support member extending away from the stator, and metallic contact caps pressed onto the pin-shaped projections so as to clamp portions of wires respectively located intermediate the pin-shaped projections and the contact caps. Contact members arranged in the electric circuit for supplying electric current to the coils are in an electric contact with the contact caps upon assembly of the electric machine. Recesses may be provided in the support member and particularly in the pin-shaped projections in which the wires are received, and the caps may be internally corrugated to clamp the wire between the respective corrugations and the respective recess of the pin-shaped projection. The annular support member may be of at least two parts which are connected to one another by cooperating complementary projections and grooves or pins and holes.
