Abstract

A modular jack assembly includes a dielectric housing means having a mating face. At least one conductive terminal has a body portion mounted in the housing and a contact arm cantilevered from the mating face. The contact arm has a contact portion near a distal end thereof for engaging a contact of a modular jack plug to flex the arm in a direction generally parallel to the mating face. The contact arm has an engaging portion located between the contact portion and the body portion. The housing has a first wall for engaging the engaging portion of the terminal and a second wall for engaging the contact portion of the terminal to prevent overflexing of the contact arm.

Claims

1. A modular jack assembly, comprising:

a dielectric housing means having a mating face;

at least one conductive terminal having a body portion mounted in the housing means and a contact arm cantilevered from the mating face of the housing means, the contact arm having a contact portion near a distal end thereof for engaging a contact of an appropriate mating connecting device to flex the contact arm in a direction generally parallel to said mating face, and the contact arm having an engaging portion located between the contact portion and the body portion; and

said housing means having a first wall for engaging the engaging portion of the terminal and a second wall for engaging the contact portion of the terminal to prevent overflexing of the contact arm, the contact portion of the contact arm being bent back onto itself to define a convex surface at a back side of the contact arm for engaging the second wall of the housing and a contact surface at a front side of the contact arm for engaging the contact of the mating connecting device.

2. The modular jack assembly of claim 1 wherein said first and second walls are generally parallel to each other and project generally perpendicular to the mating face of the housing means.

3. The modular jack assembly of claim 1 wherein said engaging portion of the contact arm comprises a bowed portion defining a convex surface for engaging the first wall of the housing means.

4. The modular jack assembly of claim 1 wherein said first wall projects from the mating face of the housing means offset from the contact arm a first distance, and the second wall projects from the mating face offset from the contact arm a second distance.

5. The modular jack assembly of claim 1, including a plurality of conductive terminals adjacent one another on the housing means, with at least one of said conductive terminals being located at each opposite end of the linear terminal array.

6. The modular jack assembly of claim 1 wherein said housing means include an inner terminal module body in which said terminal is mounted and which defines said mating face, and an outer housing defining at least one of said first and second walls.

7. The modular jack assembly of claim 6 wherein said first wall is provided on the inner terminal module body and said second wall is provided on the outer housing.

8. A modular jack assembly, comprising:

a dielectric housing means having a mating face;

at least one conductive terminal having a body portion mounted in the housing means and a contact arm cantilevered from the mating face of the housing means, the contact arm having a contact portion near a distal end thereof for engaging a contact of an appropriate mating connecting device to flex the contact arm in a direction generally parallel to said mating face, and the contact arm having an engaging portion located between the contact portion and the body portion;

said housing means having a first wall for engaging the engaging portion of the terminal and a second wall for engaging the contact portion of the terminal to prevent overflexing of the contact arm, said first and second walls being generally parallel to each other and projecting generally perpendicularly to the mating face of the housing means; and

said engaging portion of the contact arm comprising a first bowed portion defining a convex surface for engaging the first wall of the housing means, said contact portion of the contact arm comprising, at least in part, a second bowed portion defining a convex surface for engaging the second wall of the housing means, said contact portion of the contact arm is bent back onto itself to define the convex surface of second bowed portion at a back side of the contact arm, with a contact surface at a front side of the contact arm for engaging the contact of the mating connecting device.

9. The modular jack assembly of claim 8 wherein said first wall projects from the mating face of the housing means offset from the contact arm a first distance, and the second wall projects from the mating face offset from the contact arm a second distance.

10. The modular jack assembly of claim 8, including a plurality of conductive terminals adjacent one another on the housing means, with at least one of said conductive terminals being located at each opposite end of the linear terminal array.

11. The modular jack assembly of claim 8 wherein said housing means include an inner terminal module body in which said terminal is mounted and which defines said mating face, and an outer housing defining at least one of said first and second walls.

12. The modular jack assembly of claim 11 wherein said first wall is provided on the inner terminal module body and said second wall is provided on the outer housing.

13. A modular jack assembly, comprising:

a dielectric housing means having a mating face;

at least one conductive terminal having a body portion mounted in the housing means and a contact arm cantilevered from the mating face of the housing means, the contact arm having a contact portion near a distal end thereof for engaging a contact of an appropriate mating connecting device to flex the contact arm in a direction generally parallel to said mating face, and the contact arm having an engaging portion located between the contact portion and the body portion; and

said housing means having a wall projecting generally perpendicular to the mating face of the housing means for engaging the engaging portion of the terminal, and the engaging portion comprising a bowed portion defining a convex surface for engaging the wall, said housing means further including an inner terminal module body in which said terminal is mounted and which defines said mating face, and an outer housing defining said wall for engaging the engaging portion of the terminal.

14. The modular jack assembly of claim 13, including a plurality of conductive terminals adjacent one another on the housing means, with at least one of said conductive terminals being located at each opposite end of the linear terminal array.
