ABSTRACT:
A miniature electric motor has an earth strap 56 connecting one terminal 42 to a steel end plate 28. An insulating holder 40 is fixed to the end plate 28 by posts 52. The terminal 42 is supported by the holder 40 by being pressed into a passageway 48 in a boss 50 of the holder. The passageway 48 has a longitudinal groove 68 for receiving an end of the earth strap 56 which makes resilient contact with the terminal 42. The other end of the earth strap 56 is resiliently deformed between the holder 40 and the end plate 28 to establish an electrical connection between the terminal and the end plate. The end plate is in electrical contact with the casing of the motor by crimping the end of the casing over the edge of the end plate to close the casing.
