ABSTRACT:
A system for fixing a prong (100) into a wall transformer housing (200) has a slot (202) through the wall into which the prong is mechanically inserted and fastened, rather than molded into place. The prong includes a body portion (101) for insertion into a wall socket, a neck portion (102) narrower than the body that is inserted into the housing slot, a head portion (104) that protrudes into the housing after the prong neck is inserted, and a twist portion (103) between the neck portion and the head portion having a reduced cross section so that the head can twist on the neck. The prong is inserted into the slot until the shoulder (the discontinuity of the neck and body cross sections) abuts the outer surface (212), the head may be twisted relative to the neck so that the chin (the underside of the head portion) rests on the inner surface. The neck portion is held firmly within the slot between the shoulder and the chin.
