Modular jack with enhanced crosstalk performance

An electrical connector, comprising:

• a housing of dielectric material having a plurality of side walls, a plug receiving cavity opening on one side of said housing, and a circuit board receiving opening on an opposite side of said housing;
• longitudinal projections unitarily formed on an inner surface one of said side walls and extending into said plug receiving cavity, said projections having distal ends remote from said inner surface with open sided first grooves, each of said first grooves being defined by one base surface and two side surfaces extending from opposite side edges of said base surface thereof, said base surfaces of said first grooves being in a first plane;
• second grooves defined by outer lateral surfaces of said projections and by base surfaces extending between respective pairs of said lateral surfaces, said base surfaces of said second grooves being in a second plane parallel and spaced from said first plane and located adjacent said inner surface;
• first and second contacts engaged in said first and second grooves, respectively, each of said contacts having a generally straight support leg engaging one of said base surfaces, an arcuately bent portion extending from the respective support leg and a free end portion extending from the respective bent portion and across said plug receiving cavity, said bent portions of said second contacts having a greater radius of curvature than said bent portions of said first contacts, said support legs of said second contacts being longer than said support legs of said first contacts;
• and
• a printed circuit board in said circuit board receiving opening, said circuit board having first and second contact points for receiving ends of said support legs remote from said bent portions of said first and second contacts, respectively, said first and second points alternating and being aligned with said first and second grooves, respectively.

An electrical connector, comprising:

• a housing of dielectric material having a plurality of side walls and a plug receiving cavity opening on one side of said housing;
• first guide means integrally formed on an inner surface of one of said side walls and projecting into said plug receiving cavity, said first guide means including longitudinal projections extending inwardly from said one side wall into said plug receiving cavity, said projections having distal ends remote from said one side wall with open sided first grooves, each of said first grooves being defined by one base surface and two side surfaces extending from opposite side edges of said base surface;
• second guide means integrally formed on said inner surface of said one of said side walls and projecting into said plug receiving cavity and projecting from said inner surface for a distance less than that of said first guide means, said second guide means including second grooves defined by outer lateral surfaces of said projections and by base surfaces extending between ends of respective pairs of said lateral surfaces, said first and second guide means alternating along said one side wall;
• and
• first and second contacts received in said first and second guide means, respectively, said contacts having support legs engaged in said guide means, bent portions extending from said support legs and free end portions extending from said bent portions into said plug receiving cavity, said support legs of said first contacts mating with said base and side surfaces of said first grooves, said support legs of said second contacts mating with said lateral surfaces and said base surface of said second grooves.

An electrical connector, comprising:

• a housing of dielectric material having a plurality of side walls and a plug receiving cavity opening on one side of said housing;
• first guide means projecting into said plug receiving cavity relative to an inner surface of one of said side walls;
• second guide means projecting into said plug receiving cavity and located at a distance from said inner surface less than that of said first guide means, said first and second guide means alternating along a length of said one side wall;
• and
• first and second contacts received in said first and second guide means, respectively, said contacts having generally straight support legs engaged in said guide means, arcuately bent portions extending from said support legs and free end portions extending from said bent portions into said plug receiving cavity, said support legs of said first and second contacts being located in first and second parallel and spaced planes, respectively, said support legs of said second contacts being longer than said support legs of said first contacts such that said bent portions of said second contacts are spaced from said bent portions of said first contacts in directions parallel to lengths of said support legs.
