Abstract
Abstract A socket connector having an insulating body containing a plurality of contact elements in which each of the contact elements is stamped from sheet metal and has a connecting end and a pin contacting end. The pin contacting end of each contact element has a main body portion with a flat pin guiding and contacting surface and a pair of pin contact areas spaced from and facing the pin guiding and contacting surface and defined on a pair of spring arms that are cantilevered in opposite directions from a central bridge. The bridge is connected along one edge to a connecting link extending between the main body portion and the bridge and having a greater area of connection to the main body portion than to the bridge.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
183 words
A socket connector comprising: an insulating body having a plurality of contact element apertures therethrough from a connecting surface to an opposed external surface, and a plurality of contact elements, one in each of said contact element apertures, each said contact element being stamped from sheet metal and having a connecting end extending from said connecting surface and a pin contacting end within a said contact element aperture, said pin contacting end having a main body portion with a pin guiding and contacting surface and a pair of pin contact areas spaced from and facing said pin guiding and contacting surface and spaced from each other longitudinally with respect to the insertion of a pin into the contact element aperture, said pin contact areas being defined on a pair of spring arms facing said pin guiding and contacting surface and cantilevered in opposite directions from a bridge, said bridge being connected along one edge to a connecting link extending between said main body portion and said bridge and having a greater area of connection to said main body portion than to said bridge.
Claim 2
Dependent Claim
183 words
A socket connector comprising: an insulating body having a plurality of contact element apertures therethrough from a connecting surface to an opposed external surface, and a plurality of contact elements, one in each of said contact element apertures, each said contact element being stamped from sheet metal and having a connecting end extending from said connecting surface and a pin contacting end within a said contact element aperture, said pin contacting end having a main body portion with a pin guiding and contacting surface and a pair of pin contact areas spaced from and facing said pin guiding and contacting surface and spaced from each other longitudinally with respect to the insertion of a pin into the contact element aperture, said pin contact areas being defined on a pair of spring arms facing said pin guiding and contacting surface and cantilevered in opposite directions from a bridge, said bridge being connected along one edge to a connecting link extending between said main body portion and said bridge and having a greater area of connection to said main body portion than to said bridge.
Claim 3
Dependent Claim
28 words
The socket connector of claim 1 wherein said connecting link of each said contact element has a linearly decreasing cross-section from said main body portion to said bridge.
Claim 4
Dependent Claim
25 words
The socket connector of claim 1 wherein said connecting end of each of said contact elements is a bifurcate flat plate insulation displacement wire contact.
Claim 5
Dependent Claim
52 words
The socket connector of claim 1 wherein for each of said contact elements the spring arm nearest said external surface of said body extends from said bridge at an angle toward said pin guiding and contacting surface and adjacent its end is turned outward away from said pin guiding and contacting surface.
Claim 6
Dependent Claim
40 words
The socket connector of claim 4 wherein each of said spring arm extends from said bridge at an angle toward said guiding and contacting surface and adjacent its end is turned outward away from said pin guiding and contacting surface.
Claim 7
Dependent Claim
36 words
The socket connector of claim 4 wherein the spring arm farthest from said external surface of said body extends away from said bridge and is then curled back upon itself to define said pin contact area.
