Abstract
An improved cigarette lighter adapter for an electronic device has an exterior flexible covering that provides a textured surface for gripping by the user to facilitate the insertion and removal of the adapter from a cigarette lighter socket. The adapted also includes a pair of ground contacts in the form of spring members that abut ground contact pads on an internal circuit board. The ground contacts are biased in place within the adapter against the circuit board contact pads in a solderless manner. The ground contacts are positioned in alignment with each other on opposite sides of the circuit board so that contact forces they exert on the circuit board balance so as not to apply any detrimental stress to the circuit board.
