Abstract
A modular jack for a telephone, particularly for use in a handset, has a minimal height or profile by using a circuit board, on which the jack is mounted, as one of the walls defining the aperture into which a modular plug is inserted. The overall height of the jack is reduced by the thickness of the circuit board. The jack and board assembly has the smallest height dimension possible.
Claims6
A low profile circuit board mounted telephone jack assembly comprising:
- a telephone jack having a top wall, a bottom surface spaced from said top wall, and side walls extending between said top wall and said bottom surface to define a profiled aperture for reception of a telephone cord plug, said profiled aperture extending to and opening through said bottom surface;
- and a downwardly extending rib extending across said bottom surface at a front end thereof;
- a circuit board mounted on said bottom surface of said jack and forming a bottom wall to said jack and closing said profiled aperture at said bottom surface, said circuit board including an edge in abutment with said rib;
- a lead assembly mounted on one of said side walls, said lead assembly comprising a plurality of leads, each lead having a cantilever front end extending into said aperture, for contact by a contact member on a plug, each lead further including a rear end extending through said circuit board and connected to a circuit pattern on said circuit board.

- a telephone jack having a top wall, a bottom surface spaced from said top wall, and side walls extending between said top wall and said bottom surface to define an aperture for reception of a telephone cord plug, said aperture extending to and opening through said bottom surface;
- a downwardly extending rib extending across said bottom surface at a front end thereof;
- and a plurality of projections on one of said side walls, adjacent to said bottom surface;
- a circuit board mounted on said bottom surface of said jack and forming a bottom wall to said jack and closing said aperture at said bottom surface, said circuit board including an edge in abutment with said rib;
- a lead assembly mounted on said one of said side walls, said lead assembly comprising a plurality of leads, each lead having a hole therein, respective ones of said plurality of said projections on one of said side walls extending through respective holes in the leads and being deformed over said leads to retain said leads in position on said one side wall, each lead including a cantilever front end extending into said aperture, for contact by a contact member on a plug, each lead further including a rear end extending through said circuit board and connected to a circuit pattern on said circuit board.
