Abstract
Abstract A modular jack which includes a jack housing (10) made from a dielectric material such that it has a plug receiving opening (11) on a front side (10a) and a plurality of stopper projections (12) on a rear side (10b); and a plurality of jack terminals (20) made from a wire having a torsion spring characteristic and press fitted into the jack housing through the rear side and bent outwardly at press fit base portions so that they are held in place by the stopper projections with the torsion spring characteristic of the jack terminals.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
159 words
A modular jack comprising: a jack housing made from a dielectric material such that it has a plug receiving opening on a front side and a plurality of stopper projections on a rear side, and a plurality of press-fit apertures provided across said front side and said rear side; and a plurality of jack terminals made from a wire having a torsion spring characteristic so as to have a diagonally bent front contact portion, a horizontal press-fit base portion, and a rear connection portion extending first upwardly from said press-fit base portion along said rear side and then horizontally and outwardly from said rear side, with said press-fit base portion being press fitted into said press-fit apertures to fixedly retain said jack terminals and said rear connection portions being forcibly flared at said press-fit base portion to such an extent that they are held in place by said stopper projections with said torsion spring characteristic of said jack terminals.
Claim 2
Dependent Claim
159 words
A modular jack comprising: a jack housing made from a dielectric material such that it has a plug receiving opening on a front side and a plurality of stopper projections on a rear side, and a plurality of press-fit apertures provided across said front side and said rear side; and a plurality of jack terminals made from a wire having a torsion spring characteristic so as to have a diagonally bent front contact portion, a horizontal press-fit base portion, and a rear connection portion extending first upwardly from said press-fit base portion along said rear side and then horizontally and outwardly from said rear side, with said press-fit base portion being press fitted into said press-fit apertures to fixedly retain said jack terminals and said rear connection portions being forcibly flared at said press-fit base portion to such an extent that they are held in place by said stopper projections with said torsion spring characteristic of said jack terminals.
Claim 3
Dependent Claim
32 words
The modular jack of claim 1, wherein said projections has a sloped inner or upper side so that it is easy to forcibly flare said rear connection portions over said stopper projections.
Claim 4
Independent Claim
120 words
A method of broadening a pitch of jack terminals, which comprises the steps of: press fitting front contact and press-fit base portions of a plurality of wire contacts having a torsion spring characteristic into press-fit apertures of a jack housing so that said front contact and press-fit base portions of said wire contacts are fixedly aligned within said jack housing side by side with a small pitch; and forcibly flaring rear connection portions at said press-fit base portions such an extent that said rear connection portions of said wire contacts are held in place with a predetermined large pitch by stopper projections provided on a rear side of said jack housing with said torsion spring characteristic of said wire contacts.
Claim 5
Independent Claim
120 words
A method of broadening a pitch of jack terminals, which comprises the steps of: press fitting front contact and press-fit base portions of a plurality of wire contacts having a torsion spring characteristic into press-fit apertures of a jack housing so that said front contact and press-fit base portions of said wire contacts are fixedly aligned within said jack housing side by side with a small pitch; and forcibly flaring rear connection portions at said press-fit base portions such an extent that said rear connection portions of said wire contacts are held in place with a predetermined large pitch by stopper projections provided on a rear side of said jack housing with said torsion spring characteristic of said wire contacts.
