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).

Claims

1. A plug for mating a multi-conductor cable with a jack, comprising:

a housing including a first passage having a wall with an end edge;

an insulator formed to fit in said first passage, said insulator including first and second end portions and a body therebetween, said insulator further including first and second cavities in said first and second end portions, respectively, said insulator also including second and third passages through said body;

first means for conducting electricity, said first conducting means being received in the first cavity and said second passage of said insulator;

said insulator including first means for holding said first conducting means to resist retraction of said first conducting means from said first cavity and said second passage;

second means for conducting electricity, said second conducting means being received in said second cavity and said third passage of said insulator;

said insulator including second means on contact with said wall of said housing for engaging said second conducting means to resist retraction of said second conducting means from said second cavity and said third passage; and

said insulator including third means for engaging said end edge of said wall of said housing to resist removal of said insulator from said first passage in said housing, said first, second, and third engaging means being unitary with said insulator.

2. A plug in accordance with claim 1 wherein said second engaging means includes a member with a locking portion for locking said second conducting means to said insulator and a biasing portion, said wall of said housing holding said locking portion in place with respect to said biasing portion.

3. A plug in accordance with claim 1 wherein said first and second conducting means include first and second terminal portions, respectively, said first and second terminal portions both extending beyond said first cavity of said insulator.

4. A plug in accordance with claim 1 wherein said first engaging means includes a shoulder on said first conducting means and an edge on said insulator, whereby said shoulder contacts said edge to prevent retraction of said shoulder past said edge thereby preventing retraction of said first conducting means from said insulator.

5. A plug in accordance with claim 1 wherein said second conducting means includes a first edge and said second engaging means includes a depending arm on said insulator with a cam extending outwardly from said arm and a second edge at the end of said arm, the wall of said first passage forcing said cam inwardly to butt said second edge of said arm against said first edge of said second conducting means whereby said second conducting means is prevented from retracting from said insulator.

6. A plug in accordance with claim 1 including means for resisting rotation of said insulator with respect to said housing.

7. A plug in accordance with claim 1 wherein said housing is conductive, said plug including means for connecting a ground shield of said cable to said housing.

8. A plug for mating with a jack, comprising:

a housing having a first axial passage therethrough with a wall and a first radial edge extending away from said wall;

an insulator formed to be received in the first passage of said housing, said insulator having a body and a cylindrical sleeve extending from one end of the body and a pair of opposing first arms extending from the other end of the body, said first arms having radially outwardly extending collars at ends thereof, said collars engaging said first edge to prevent said insulator from retracting from said first passage, said insulator further including a split planar wall extending between said first arms, said insulator also having a second arm depending from said sleeve, said second arm having a cam surface facing outwardly from the axis of said sleeve, and a second edge at the end of said second arm, said insulator including a second axial passage and a third passage through said body, said second passage including a third radial edge extending away therefrom;

a first conductor with a probe contactor at a first end and a first terminal at a second end, said first conductor including a shoulder extending outwardly from the probe contactor said first conductor also including a gland between the shoulder and the first terminal, said shoulder engaging said third radial edge when said probe contactor passes through said second passage, said gland being received between said first arms of said insulator on one side of said split planar wall, said planar wall and said gland mating to prevent rotation of said first conductor with respect to said insulator;

a second conductor having a contactor member and a second terminal, said contactor member including a fourth edge oriented radially with respect to the axis of said plug, the second edge of said arm engaging the fourth edge of said second conductor when said first arm is cammed by the wall of said first passage in said housing when said insulator is installed in said housing, said second and fourth edges engaging to prevent said second conductor from retracting from said insulator; and

means for locking said plug to said jack, said locking means being attached to said housing.
