ABSTRACT:
A cigarette lighter adapter for use in a cigarette lighter adapter assembly enables use of a cellular phone while driving in an automobile. By plugging the adapter into a car cigarette lighter, power is provided from the car battery to the cell phone. The adapter includes a plunger retention mechanism for insuring that a metal contact plunger of the adapter is not lost while replacing or checking a fuse in the adapter. In a preferred aspect of the invention, the adapter further includes a force-absorbing element to prevent force from being accidentally applied to the plunger retention mechanism by the metal contact plunger not only while the adapter is assembled and in use, but also should the adapter be accidentally dropped and unforeseen force applied to the plunger.
