ABSTRACT:
An electrical jack having a housing of insulating material with integral walls thereof forming a cavity. A front wall of the housing has an axially extending hollow collar member with a passageway for guiding a stem of a jack plug into the cavity. A plurality of spring contactor electrodes are disposed within the housing cavity and are adapted to engage predetermined portions of the jack plug stem when such stem is inserted into the cavity to establish electrically conductive paths between the contactor electrodes and the portions of the jack plug. An additional electrical contactor, having an aperture formed in a mounting portion thereof, is disposed around the collar member, such mounting portion being disposed outside the housing cavity. The additional electrical contactor has a finger electrode protruding across the front wall into the cavity to electrically contact a portion of the inserted jack stem. With such arrangement, in applications where it is desired to have such contacted portion of the jack plug electrically connected to a conductive mounting panel disposed orthogonal to the axis of the plug, the mounting portion of the electrical contactor is placed in contact with the panel and where such electrical contact to the panel is not desired an insulated washer is used to insulate the contactor from the panel. The additional electrical contactor also has integrally formed spring members for clamping a cover for such cavity to the housing and an electrode adapted for electrically connecting the contactor to a horizontally disposed printed circuit board.
