Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
174 words
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.
Claim 2
Dependent Claim
174 words
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.
Claim 3
Dependent Claim
48 words
A telephone jack assembly as claimed in claim 1, including a plurality of spaced parallel ribs on said one side wall at a front end thereof, said ribs extending down said front end of said one side wall to said aperture, said leads positioned between said parallel ribs.
Claim 4
Dependent Claim
31 words
A telephone jack assembly as claimed in claim 2, including a further plurality of spaced ribs on said side wall at said bottom surface, said leads positioned between said further ribs.
Claim 5
Dependent Claim
48 words
A telephone jack assembly as claimed in claim 1, including first projections on said bottom surface, said first projections extending through holes in said circuit board and being deformed over a surface of the circuit board remote from said jack, to retain said jack on said circuit board.
Claim 6
Dependent Claim
60 words
A telephone jack assembly as claimed in claim 1, said jack being mounted on a top surface of said circuit board, said circuit pattern formed on a bottom surface of said circuit board, and further including a transducer and at least one associated electrical component mounted on said top surface of said circuit board and connected to said circuit pattern.
Claim 7
Dependent Claim
231 words
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 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.
Claim 8
Dependent Claim
231 words
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 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.
