Abstract
Abstract A compliant electrical connector pin has opposed convex surfaces to grip the surfaces of a hole in a circuit board, the pin having a compliant region so that the pin compresses to reduce the cross sectional area of the pin as the pin is inserted into the hole with the pin having a transition zone proximate the compliant region with the transition zone and the compliant region sufficiently interriated so that the transition zone partially expands the hole in the circuit board before the hole in the circuit board begins to compress the compliant region of the pin with the compliant region and the hole coacting to provide a low resistance electrical connection between mat-, ing surfaces of the hole and the pin without rupturing the material on the side walls of the hole with the compliant pin structure being able to withstand vibration without fracturing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
101 words
A smooth surfaced compliant pin for forming a low resistance electrical connection, said compliant pin having a first section, a transition zone and a compliant region, said transition zone characterized by forming a transition angle of approximately 15° or less with said first section, said compliant region extending sufficiently far into said transition zone so that upon insertion of said compliant pin into the opening in a circuit board the opening in the circuit board is only partially required to expand before said compliant region resiliently deforms to form resilient contact between the opening in the circuit board and said compliant-region.
Claim 2
Dependent Claim
101 words
A smooth surfaced compliant pin for forming a low resistance electrical connection, said compliant pin having a first section, a transition zone and a compliant region, said transition zone characterized by forming a transition angle of approximately 15° or less with said first section, said compliant region extending sufficiently far into said transition zone so that upon insertion of said compliant pin into the opening in a circuit board the opening in the circuit board is only partially required to expand before said compliant region resiliently deforms to form resilient contact between the opening in the circuit board and said compliant-region.
Claim 3
Dependent Claim
33 words
The invention of claim 1 wherein said compliant region has a compliant surface and at least a portion of said compliant surface is similar in shape to the opening in the circuit board.
Claim 4
Dependent Claim
28 words
The invention of claim 2 wherein the opening in the circuit board is of cylindrical shape and said compliant pin has a cylindrical mating surface of similar shape.
Claim 5
Dependent Claim
146 words
A compliant pin having a radiused surface for forming an electrical connection to a receptacle without damaging the conducting surfaces of the receptacle comprising: a conducting member; said conducting member including a compliant region having a surface operable for resilient displacement so that when said surface on said compliant region is in contact with a conducting surface of a receptacle said surface on said compliant region is held in contact with the conducting surface of a receptacle to provide a low resistance electrical connection between said surface on said compliant region and the conducting surface of a receptacle; a transition region on said conducting member, said transition region including an interface zone and a deforming zone with said compliant region extending substantially into said interface zone so that insertion of said pin into a receptacle produces only expansion of the receptacle without rupture of the receptacle.
Claim 6
Dependent Claim
146 words
A compliant pin having a radiused surface for forming an electrical connection to a receptacle without damaging the conducting surfaces of the receptacle comprising: a conducting member; said conducting member including a compliant region having a surface operable for resilient displacement so that when said surface on said compliant region is in contact with a conducting surface of a receptacle said surface on said compliant region is held in contact with the conducting surface of a receptacle to provide a low resistance electrical connection between said surface on said compliant region and the conducting surface of a receptacle; a transition region on said conducting member, said transition region including an interface zone and a deforming zone with said compliant region extending substantially into said interface zone so that insertion of said pin into a receptacle produces only expansion of the receptacle without rupture of the receptacle.
Claim 7
Dependent Claim
54 words
The invention of claim 4 wherein said transition region has a surface of predetermined curvature and the receptacle in the circuit board has a surface with a curvature approximately equal to the predetermined curvature of the surface of the transition region to permit mating engagement of the transition region surface and the receptacle surface.
Claim 8
Dependent Claim
11 words
The invention of claim 5 wherein said transition region is tapered.
