ABSTRACT:
A dual purpose jack (20) connectable to a printed circuit board is capable of accepting an audio plug and a power plug. The audio plug (50) has a projecting pin containing a series of spaced annular external contacts connectable to an audio signal. The projecting pin includes a hollow insulated sleeve which mates with a metal pin (120) of the jack to insulate the audio plug from the power portion of the jack. The power plug (40) includes a projecting pin (42) which is hollow and mates with the metal pin (120) of the jack to form the power contact. The combination jack has various leaf springs which move into engagement with the projecting pins of the two plugs and which are aligned in different planes in order to assist in miniaturization of the jack.
