Abstract

Abstract Disclosed is a modular jack having a first plurality of wires which extend in a common vertical plane from the bottom wall of the housing across the opened end and to the top wall and then extend horizontally forward and then angularly downwardly and rearwardly back toward the rear opened end. A second plurality of wires extends first in a common vertical plane from the bottom wall across only a part of the rear opened end and then extends obliquely, horizontally and upwardly toward the front opened end. A method of use is also disclosed.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 384 words
A method for reducing electrical crosstalk and common mode interference in a modular jack assembly for receiving another connecting element having contacts for signal transmission comprising the steps of: (a) providing an outer insulative housing having top and bottom walls and opposed lateral walls all defining an interior section and said housing also having front and rear open ends; (b) positioning a first plurality of generally parallel conductive means in said insulative housing in a first arrangement of planar sections which is comprised of a common rear planar section having an upper edge, a common upper planar section extending forwardly from the upper edge of said rear planar section and itself having a front edge and a common terminal oblique planar section having a first terminal edge sloping downwardly and rearwardly from said front edge of said upper planar section; (c) positioning a second plurality of generally parallel conductive means in said insulative housing in a second arrangement of planar sections which has a common lower planar section having an upper edge and a common oblique planar section extending upwardly and forwardly from said upper edge in a common oblique planar section having a second terminal edge which extends beyond the first terminal edge of the oblique planar section of the first plurality of conductive means such that said oblique planar sections of the first and second plurality of conductive means are positioned in overlapping relation and the portions of both of said first and second pluralities of conductive means that are located in said oblique planar sections are positioned for engaging the contacts of said other connecting element when said other connecting element is inserted into the front open end of the housing for signal transmission; and (d) providing an insulative insert in which said first plurality of conductive means are at least partially retained and said insulative insert has an upper section having a base and upper sides and a rear and terminal ends and is positioned so that the base side of said insulative insert is superimposed over the rear open end of the insulative housing and the upper end of said insulative insert is adjacent the top side of the insulative housing such that the terminal end of said insulative insert extends into the interior section of the insulative housing.
Claim 2
Independent Claim 384 words
A method for reducing electrical crosstalk and common mode interference in a modular jack assembly for receiving another connecting element having contacts for signal transmission comprising the steps of: (a) providing an outer insulative housing having top and bottom walls and opposed lateral walls all defining an interior section and said housing also having front and rear open ends; (b) positioning a first plurality of generally parallel conductive means in said insulative housing in a first arrangement of planar sections which is comprised of a common rear planar section having an upper edge, a common upper planar section extending forwardly from the upper edge of said rear planar section and itself having a front edge and a common terminal oblique planar section having a first terminal edge sloping downwardly and rearwardly from said front edge of said upper planar section; (c) positioning a second plurality of generally parallel conductive means in said insulative housing in a second arrangement of planar sections which has a common lower planar section having an upper edge and a common oblique planar section extending upwardly and forwardly from said upper edge in a common oblique planar section having a second terminal edge which extends beyond the first terminal edge of the oblique planar section of the first plurality of conductive means such that said oblique planar sections of the first and second plurality of conductive means are positioned in overlapping relation and the portions of both of said first and second pluralities of conductive means that are located in said oblique planar sections are positioned for engaging the contacts of said other connecting element when said other connecting element is inserted into the front open end of the housing for signal transmission; and (d) providing an insulative insert in which said first plurality of conductive means are at least partially retained and said insulative insert has an upper section having a base and upper sides and a rear and terminal ends and is positioned so that the base side of said insulative insert is superimposed over the rear open end of the insulative housing and the upper end of said insulative insert is adjacent the top side of the insulative housing such that the terminal end of said insulative insert extends into the interior section of the insulative housing.
