ABSTRACT:
A self-attaching protective cover that is attached to the end frame of an alternating current generator. The end frame of the generator has a plurality of circumferentially spaced openings. Each opening has an edge that is comprised of first and second frame surfaces that intersect. The first frame surface is parallel to the longitudinal axis of the end frame and the second frame surface is inclined or slanted so as to be located at an angle to the first frame surface. The cover is a one-piece part formed of plastic material and has a plurality of circumferentially spaced and axially extending latch arms. The cover is attached to the end frame by pushing the latch arms into the openings in the end frame. As this occurs, the latch arms are sprung or forced radially outwardly and they subsequently spring back to cause slanted surfaces on the latch arms to tightly engage the slanted surfaces on the end frame and to cause other surfaces on the latch arms to tightly engage the first frame surfaces.
