Abstract
Abstract A circuit testing clamp constructed for use with integrated circuits having two body members forming a clamping jaw operated by a spiral spring. A plurality of contact pads on opposing surfaces of the contact jaws are connected to leads which pass through the body and extend out the upper end to eyelets for easy attachment of test probes. To provide the maximum separation for attachment of test probes, alternate leads are brought out of the body of the clamp at 90* angles. The body of the clamp is composed of a hard heat resistant insulating material hinged together to maintain pressure at the contact area by the tension of the spiral spring.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
148 words
An integrated circuit test clamp comprising: a first solid body member; a second solid body member hingedly connected to the first solid body member to form a clamping jaw; a spring between said first and second body members biasing said jaw toward a closed position; a plurality of contact pads along the edge of said first and second body members forming the clamping jaws; a wire lead connected to each contact pad extending through said solid body members and out of the upper surface; and means providing maximum separation between adjacent leads; said means for providing maximum separation comprising alternately extending leads out the top and side of said solid body members, respectively; the leads extending out of the sides being substantially perpendicular to the plane of the contact pads whereby shorting of leads is minimized by the physical separation and the solid body material between adjacent leads.
Claim 2
Dependent Claim
148 words
An integrated circuit test clamp comprising: a first solid body member; a second solid body member hingedly connected to the first solid body member to form a clamping jaw; a spring between said first and second body members biasing said jaw toward a closed position; a plurality of contact pads along the edge of said first and second body members forming the clamping jaws; a wire lead connected to each contact pad extending through said solid body members and out of the upper surface; and means providing maximum separation between adjacent leads; said means for providing maximum separation comprising alternately extending leads out the top and side of said solid body members, respectively; the leads extending out of the sides being substantially perpendicular to the plane of the contact pads whereby shorting of leads is minimized by the physical separation and the solid body material between adjacent leads.
Claim 3
Dependent Claim
24 words
The circuit test clamp according to claim 1 further including eyelets on the end of each lead to permit positive connection of test probes.
Claim 4
Dependent Claim
28 words
The circuit test clamp according to claim 2 wherein said contact pads are separated by ridges to prevent adjacent contacts from being bridged by an integrated circuit lead.
