Abstract: A locking handle assembly used in combination with printed wiring boards and the like has camming portions which cooperate with a rod on the housing for the boards to act as a lever thereby positively seating and unseating its associated board within the housing. The handle assembly is provided with locking serrations. The serrations are positioned along radial curves so the handle is allowed to undertravel or overtravel, thereby compensating for tolerance buildup which could prevent proper seating of printed wiring assembly. An electrostatic discharge clip of the handle assembly engages the rod on the housing to ground the same and thereby prevent static electricity from the operator from producing an adverse effect on the electronic components.

Abstract: A mounting device for mechanically retaining separable transfomer core portions together and attaching the transformer assembly to a printed circuit board utilizing a flat clip body and a vertically aligned spring unit to minimize the transformer assembly height and four mounting legs to allow easy installation and removal.
