ABSTRACT:
A dynamoelectric machine having a thermal protector held in intimate thermal contact with the machine's electrical winding by a spring inserted between the machine's enclosing frame and protector. The spring is generally a V-shaped member whose one leg mates with the protector and whose other leg is divided in two with each of those divided legs being engageable with the frame. The closed end of the V-shaped spring member is progressively inserted between the protector and frame with the open end following. The frame engageable legs are sharp and thus gouge into the relatively softer frame so as to resist relative movement between the spring member and frame in the direction opposite its insertion.
