Abstract
Abstract A test socket which is for an integrated circuit device and which includes clamp wings pivotally mounted to the socket frame side faces. Each clamp wing includes conductive biased leads terminating in contacts which overlie and contact the leads of the integrated circuit device, serving to retain the device within the socket frame while completing an electrical circuit between a printed circuit board and the integrated circuit device.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
169 words
A test socket for an integrated circuit device having a body with leads extending therefrom, said socket comprising a base having upper and lower faces and spaced side faces, said base upper face adapted to accommodate said device body with said device leads overlying said upper face, a clamp wing pivotally mounted to said base adjacent a said side face thereof, said wing being shiftable between an open position wherein the wing extends outwardly of said base upper face and a closed position wherein the wing is located adjacent the base upper face, and biasing means contacting said wing and base for urging said wing into its said closed position, a conductive contact means carried by and extending laterally from said wing; said contact means for wiping across said device leads as said wing is urged into its said closed position and for overlying and contacting said device leads when said wing is in its said closed position to create an electrical connection between the socket and device leads.
Claim 2
Dependent Claim
169 words
A test socket for an integrated circuit device having a body with leads extending therefrom, said socket comprising a base having upper and lower faces and spaced side faces, said base upper face adapted to accommodate said device body with said device leads overlying said upper face, a clamp wing pivotally mounted to said base adjacent a said side face thereof, said wing being shiftable between an open position wherein the wing extends outwardly of said base upper face and a closed position wherein the wing is located adjacent the base upper face, and biasing means contacting said wing and base for urging said wing into its said closed position, a conductive contact means carried by and extending laterally from said wing; said contact means for wiping across said device leads as said wing is urged into its said closed position and for overlying and contacting said device leads when said wing is in its said closed position to create an electrical connection between the socket and device leads.
Claim 3
Dependent Claim
48 words
The socket of claim 1 wherein said base upper face has a device-receiving opening formed therein, said device-receiving opening for accommodating the body of said device, oppositely spaced grooves extending along said base upper face to said device-receiving opening, said grooves for receiving the leads of said device.
Claim 4
Dependent Claim
17 words
The socket of claim 1 wherein said biasing means constitutes a conductive extension of said contact means.
Claim 5
Dependent Claim
26 words
The socket of claim 3 wherein said biasing means extends downwardly from said base and constitutes lead means for connecting said socket to a power source.
Claim 6
Dependent Claim
22 words
The socket of claim 2 wherein said device-receiving opening terminates in a bottom wall located between said base upper and lower faces.
Claim 7
Dependent Claim
144 words
The socket of claim 1 and a second clamp wing pivotally mounted to said base adjacent an opposite side face from said first mentioned wing, said second mentioned wing being shiftable between an open position where the wing extends outwardly of said base upper face and a closed position wherein the wing is located adjacent the base upper face, and biasing means contacting said second mentioned wing and said base for urging the wing into its closed position, a second conductive contact means carried and extending laterally from by said second mentioned wing, said second contact means for wiping across said device leads as said second mentioned wing is urged into its said closed position and for overlying and contacting said device leads when said second mentioned wing is in its closed position to create an electrical connection between the socket and device leads.
Claim 8
Dependent Claim
37 words
The socket of claim 6 wherein said second mentioned biasing means constitutes a conductive extension of each second contact means and extends downwardly from said base to form leads for connecting said socket to a power source.
Claim 9
Dependent Claim
21 words
The socket of claim 7 wherein one of said wings includes at least two of said contact means and associated leads.
Claim 10
Dependent Claim
29 words
The socket of claim 8 wherein said wings include an angled upper face whereby said wings may be urged into their said open position by a wing opening tool.
Claim 11
Dependent Claim
28 words
The socket of claim 6 wherein each wing includes a stop means engageable with said base for limiting outward shifting movement of the wings into their open position.
Claim 12
Dependent Claim
34 words
The test socket of claim 1 wherein said socket base includes shoulder means for supporting said device leads, said contact means overlying said shoulder means when said wing is in its said closed position.
Claim 13
Dependent Claim
34 words
The test socket of claim 3 wherein one of said base side faces has an exterior groove therein extending between said base upper and lower faces, said biasing means positioned within said base groove.
Claim 14
Dependent Claim
35 words
The test socket of claim 7 wherein said base side faces have exterior grooves therein extending between said base upper and lower faces, said first and second mentioned biasing means positioned within said base grooves.
Claim 15
Dependent Claim
41 words
The test socket of claim 6 wherein said socket base includes shoulder means for supporting said device leads, said first mentioned and second contact means overlying said shoulder means when said first and second mentioned wings are in their closed positions.
