  • Electrical connector apparatus
    Patent number: 4759729
    Abstract: The present invention is directed to connector apparatus comprising a jack (20) usable with either a conventional plug (400) terminating a coaxial cable (410) or a special plug (200) terminating a shielded, twisted pair cable (202). Such versatility was made possible by a full body first conductor (68) having spring contactors (130) which may be separated from grounding contact with barrel (36) of housing (32) by an insulator (216) of plug (200) includes a protruding insulator (216) for separating the contactors (130) and functioning the switching mechanism. Plug (200) also includes first and second conductors (212) and (214) for connection with second and first jack conductors (76) and (68), respectively. In addition, unique structures for pieceparts and assembly details resulting in various interlocking arrangements are disclosed with respect to the structure of jack (20) and plug (200).
    Type: Grant
    Filed: November 6, 1984
    Date of Patent: July 26, 1988
