4. The electrical connector assembly as defined in claim 1 wherein,

said first and second tabs are pre-loaded such that said first and second tabs press outwardly when inserted within said first and second cavities.

5. The electrical connector assembly as defined in claim 1 wherein,

said first latch means includes a first protrusion formed in said first cavity and a first slot formed in said first tab and sized to receive the first protrusion when said first tab is received within said first cavity;

said second latch means includes a second protrusion formed in said second cavity and a second slot formed in said second tab and sized to receive said first protrusion when said second tab is received within said second cavity; and

said first and second tabs are pre-loaded such that said first and second tabs press outwardly when inserted within said first and second cavities.

6. The electrical connector assembly as defined in claim 1 wherein,

said flange abuts against said mounting surface of said bracket when said first and second tabs are received within said first and second cavities.

7. The electrical connector assembly as defined in claim 1 wherein said insulative housing further includes:

first and second shoulders upstanding from opposite sides of said base portion of said insulative housing adjacent to said upstanding portion.

8. The electrical connector assembly as defined in claim 7 wherein:

said first shoulder abuts against said first tab received within said first cavity and said second shoulder abuts against said second tab received within said second cavity.

9. The electrical connector assembly as defined in claim 7 wherein,

said first and second shoulders substantially surround said upstanding portion.

10. An electrical connector assembly comprising:

a insulative housing including a base portion, and an upstanding portion defining a plurality of conduits for housing individual electrical contacts;

a metal housing including a flange, a shell upstanding from said flange and defining a first opening sized to receive and encompass said upstanding portion of the insulative housing, and first and second tabs depending downward from said flange, said first tab defining a first slot formed therein and said second tab defining a second tab formed therein;

a bracket including a mounting surface that defines a second opening sized to permit passage therethrough of said upstanding portion of said insulative housing, said mounting surface also defining first and second cavities on opposite sides of said second opening sized to receive said first and second tabs when said first and second openings are aligned;

first latch means for securing said first tab to said bracket when said first tab is received within said first cavity said latch means including a first protrusion formed in said first cavity and sized to snugly fit within the first slot defined by said first tab when said first tab is inserted within said first cavity;

second latch means for securing said second tab to said bracket when said second tab is received within said second cavity said latch means including a second protrusion formed in said second cavity and sized to snugly fit within the second slot defined by said second tab when second tab is inserted within said second cavity; and

first and second shoulders upstanding from opposite sides of said base portion of said insulative housing adjacent to said upstanding portion such that said first shoulder abuts against said first tab received within said first cavity and said second shoulder abuts against said second tab received within said second cavity.

11. The electrical connector assembly as defined in claim 10 wherein,
