Abstract
Abstract An electrical connector having terminals disposed in a body, which terminals have terminations in one face disposed in two rows and in columns and the terminals have tail portions which protrude from the other face with the terminal ends thereof disposed in a single row and the terminals are disposed to form mirror images about a plane perpendicular to the rows and through a midpoint between terminals to reduce possible crosstalk.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
109 words
An electrical connector having two rows of connecting terminals, each of said connecting terminals having a tail portion which protrudes from one end thereof in such a manner that the tail portions are bent and as a whole are aligned in a row, and said connector is adapted to be electrically connected to a cable by means of said tail portions, wherein said tail portions are disposed at positions symmetrical with each other about a plane which is perpendicular to the direction in which said row of tail portions extends and which passes between two said connecting terminals adjacent to each other in the extending direction of said row.
Claim 2
Dependent Claim
109 words
An electrical connector having two rows of connecting terminals, each of said connecting terminals having a tail portion which protrudes from one end thereof in such a manner that the tail portions are bent and as a whole are aligned in a row, and said connector is adapted to be electrically connected to a cable by means of said tail portions, wherein said tail portions are disposed at positions symmetrical with each other about a plane which is perpendicular to the direction in which said row of tail portions extends and which passes between two said connecting terminals adjacent to each other in the extending direction of said row.
Claim 3
Dependent Claim
20 words
A connector according to claim 1, wherein the other end of each of said connecting terminals forms a female contact.
Claim 4
Dependent Claim
21 words
A connector according to claim 1 or 2, wherein each of said connecting terminals is formed by a bent metal sheet.
Claim 5
Dependent Claim
69 words
An electrical connector having two rows of connecting terminals, each of said terminals having a first end disposed in one of said rows and a second tail portion end for connection to a wire of a cable, said terminals each having a first or second configuration with each said row having alternating terminals of said first and second configurations, opposing said terminals in said rows having the same configuration.
Claim 6
Dependent Claim
69 words
An electrical connector having two rows of connecting terminals, each of said terminals having a first end disposed in one of said rows and a second tail portion end for connection to a wire of a cable, said terminals each having a first or second configuration with each said row having alternating terminals of said first and second configurations, opposing said terminals in said rows having the same configuration.
Claim 7
Dependent Claim
60 words
An electrical connector according to claim 4, wherein said terminals are formed of conductive metal sheets of two dissimilar patterns, each said pattern having a plurality of fold lines to form a female terminal on said first terminal end and projecting said tail portions which are plane at said second ends, said tail portions being disposed in a single row.
