Abstract

Circuit board housing comprises spaced-apart panels with the circuit board being between the panels. A modular jack is mounted on one surface of the circuit board and the panels have laterally extending flanges which form a wall of the circuit board housing. One of the flanges is provided with an opening which is in alignment with the opening in the modular jack. The modular jack has a clearance notch extending into one of its sidewalls and the circuit board has a similar notch in registry with the clearance notch, these notches providing clearance for an inserted modular plug. The latching shoulder for the modular jack is provided on one of the flanges rather than in the jack housing. These features, the latching shoulder on the flange and the clearance notches, permit a reduction in the thickness of the circuit board housing as measured between the panels.

Claims

1. The combination of a modular jack receptacle mounted on one surface of a circuit board and a first panel which extends parallel to, and is spaced from, the other surface of the circuit board, the modular jack receptacle comprising an insulating housing having a mating end and a rearward end, a plug receiving opening extending into the mating end, the opening having opposed internal endwalls and first and second opening sidewalls, the housing having oppositely facing external endwalls and first and second external sidewalls which are proximate to the first and second opening sidewalls, a plurality of conductors in side-by-side relationship, each conductor having a contact portion which extends from the first opening sidewall diagonally into the opening from a location adjacent to the mating end and a lead portion which extends to the rearward end of the housing and to the one surface of the circuit board, the opening having latching shoulder means therein facing inwardly of the mating end for cooperation with a complementary latching shoulder on a modular plug, the combination of the modular jack receptacle, the circuit board, and the panel being characterized in that:

the circuit board has one edge which extends parallel to one edge of the first panel, the first panel having a lip extending from the one edge thereof towards the one edge of the circuit board, the lip having an internal surface which is parallel to and adjacent to the one edge of the circuit board,

the modular jack being mounted on the circuit board adjacent to the one edge thereof and being oriented with the mating end extending normally of the plane of the circuit board and parallel to the lip of the first panel,

the lip having a recess therein which is centrally located with respect to the plug-receiving opening, the lip constituting at least portions of the mating end of the modular jack, the latching shoulder means of the modular jack being on the internal surface of the lip adjacent to the recess in the lip.

2. The combination set forth in claim 1 characterized in that the circuit board has a circuit board notch extending inwardly from the one edge thereof, the circuit board notch being in alignment with the recess in the lip, and the modular jack has a clearance notch therein extending inwardly from the mating end, the clearance notch being in registry with the circuit board notch thereby to provide clearance for a modular plug upon insertion of the plug into the plugreceiving opening.

3. The combination set forth in claim 2 characterized in that the conductors in the modular jack are stamped and formed sheet metal conductors, the conductors extending across the rearward end of the modular jack and to circuit board conductors on the circuit board.

4. The combination set forth in claim 3 characterized in that a second panel extends parallel to the first panel, the second panel having an internal surface which is against the first external sidewall of the modular jack, the second panel having a flange extending towards the lip of the first panel, the flange having an opening therein, the mating end of the modular jack being in the opening.

5. The combination set forth in claim 4 characterized in that interengaging means are provided on the second panel and on the modular jack for maintaining the modular jack in position on the circuit board and in the opening in the flange.

6. The combination set forth in claim 5 characterized in that the interengaging means comprises ribs on the endwalls of the modular jack and rib-receiving recesses in the flange.

7. The combination set forth in claim 1 characterized in that a second panel extends parallel to the first panel, the second panel having an internal surface which is against the first external sidewall of the modular jack, the second panel having a flange extending towards the lip of the first panel, the flange having an opening therein, the mating end of the modular jack being in the opening.
