Abstract
Abstract An improvement is provided in an electrical connector system which includes a connector block of insulating material having a plurality of pin receiving openings for positioning a plurality of terminal pins therein by an interference fit. At least some of the openings each are generally rectangularly shaped and include inwardly directed pin engaging projections located in diagonally opposite quadrants of the rectangular opening. The invention contemplates that the connector block may have a series of the openings in a closely spaced row. The diagonally opposite quadrants in which the projections are disposed are at the same respective locations in each opening along the row.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
125 words
In an electrical connector system which includes a connector block of insulating material having a pin receiving opening for positioning a terminal pin therein by a close fit therewith, the improvement comprising said opening being generally rectangularly shaped defining an "X" axis through the mid-point of two opposite sides of the rectangular opening and a "Y" axis through the mid-point of the other two opposite sides of the rectangular opening, the axes in turn defining rectangular quadrants of the opening, the axes in turn defining rectangular quadrants of the opening, and including inwardly directed pin engaging projections located in diagonally opposite quadrants of the rectangular opening wherein one of said projections is located on each side of the rectangular opening in said diagonally opposite quadrants.
Claim 2
Dependent Claim
125 words
In an electrical connector system which includes a connector block of insulating material having a pin receiving opening for positioning a terminal pin therein by a close fit therewith, the improvement comprising said opening being generally rectangularly shaped defining an "X" axis through the mid-point of two opposite sides of the rectangular opening and a "Y" axis through the mid-point of the other two opposite sides of the rectangular opening, the axes in turn defining rectangular quadrants of the opening, the axes in turn defining rectangular quadrants of the opening, and including inwardly directed pin engaging projections located in diagonally opposite quadrants of the rectangular opening wherein one of said projections is located on each side of the rectangular opening in said diagonally opposite quadrants.
Claim 3
Dependent Claim
30 words
The improvement of claim 1 wherein said projections each have an inwardly facing pin engaging surface generally parallel to the side of the rectangular opening from which the projection projects.
Claim 4
Dependent Claim
31 words
The improvement of claim 1 wherein each projection is offset from but immediately adjacent the respective axis which passes through the respective side of the opening from which the projection projects.
Claim 5
Dependent Claim
30 words
The improvement of claim 1 wherein said projections each have an inwardly facing pin engaging surface generally parallel to the side of the rectangular opening from which the projection projects.
Claim 6
Dependent Claim
37 words
The improvement of claim 1 wherein the connector block has a series of said openings in a closely spaced row, with said diagonally opposite quadrants being at the same respective locations in each opening along the row.
