Abstract

A low profile shielded jack is provided for mounting to a circuit board and for receiving a mating plug. The jack includes a substantially rectangular dielectric housing and a one-piece, substantially rectangular shield substantially surrounding the housing. Recesses are provided in a bottom board mounting wall of the housing at the juncture of the bottom wall with front or side walls of the housing. Supporting tabs at bottom edges of the shield extend into the recesses. The depths of the recesses are at least equal to the thicknesses of the supporting tabs so that the tabs do not project downwardly beyond the bottom board mounting wall of the housing.

Claims

1. In a low profile shielded jack for mounting to a circuit board and for receiving a mating plug, the jack including

a substantially rectangular dielectric housing having a front face, a bottom board mounting wall, and a top, rear and a pair of side walls substantially surrounding a plug-receiving cavity extending rearwardly from the front face for receiving a mating plug connector, where both a bottom portion of said front face and a front portion of said bottom board mounting wall being open to define an opening communicating with the cavity for accommodating a depending latch arm of a plug connector,

a plurality of terminals mounted in the housing for making electrical contact with corresponding terminals on the plug connector when inserted into the plug-receiving cavity,

a one-piece, substantially rectangular shield stamped and formed of conductive material and having front, top, rear and side wall portions substantially surrounding and shielding the front face and the top, rear and side walls, respectively, of the dielectric housing,

wherein the improvement comprises

at least two recesses in the bottom board mounting wall of the housing at the juncture thereof with the front face of the housing, one of said recesses provided at opposite sides of said opening,

supporting tabs at a bottom edge of the front wall portion of the shield and extending rearwardly into said recesses, and

the depth of said recess being at least equal to the thickness of said supporting tab so that the tab does not project downwardly beyond the bottom board mounting wall of the housing.

2. In a low profile shielded jack as set forth in claim 1, wherein the depths of said pair of recesses being at least equal to the thicknesses of said pair of supporting tabs so that the pair of supporting tabs do not project downwardly beyond the bottom board mounting wall of the housing.

3. In a low profile shielded jack as set forth in claim 2, wherein a second pair of recesses are located in the bottom board mounting wall at the juncture of the bottom and side walls of the housing with the rear wall of the housing and including a complementary second pair of rear supporting tabs at the rear bottom edge of the side wall portion of the shield for extending into the second recesses.

4. In a low profile shielded jack as set forth in claim 3 wherein the depths of said second pair of recesses being at least equal to the thicknesses of said second pair of supporting tabs so that the second pair of supporting tabs do not project downwardly beyond the bottom board mounting wall of the housing.
