Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
A metal circuit board pin having a longitudinally extending generally square first portion with four parallel corners and flat sides joining said corners, and a second portion located at one end of said first portion adapted to be inserted in a hole in a circuit panel, said second portion including two pairs of longitudinally extending collapsible fins, each fin forming a longitudinal extension of one of said corners and projecting outwardly beyond the periphery of said first portion, said second portion also including a pair of opposed longitudinally extending recesses each positioned between a pair of adjacent fins, said recesses being located inwardly of the periphery of said first portion, each fin including a circuit panel-engaging edge with the edges of each pair of fins located between planes passing through the longitudinal axis of the pin and the corners from which such fins extend.
Claim 2
Dependent Claim
144 words
A metal circuit board pin having a longitudinally extending generally square first portion with four parallel corners and flat sides joining said corners, and a second portion located at one end of said first portion adapted to be inserted in a hole in a circuit panel, said second portion including two pairs of longitudinally extending collapsible fins, each fin forming a longitudinal extension of one of said corners and projecting outwardly beyond the periphery of said first portion, said second portion also including a pair of opposed longitudinally extending recesses each positioned between a pair of adjacent fins, said recesses being located inwardly of the periphery of said first portion, each fin including a circuit panel-engaging edge with the edges of each pair of fins located between planes passing through the longitudinal axis of the pin and the corners from which such fins extend.
Claim 3
Dependent Claim
45 words
A circuit pin as in claim 1 wherein at one end of said second portion the height of the fins outwardly of the pin is gradually decreased to provide a tapered lead-in to facilitate insertion of the portion within a hole in a circuit panel.
Claim 4
Dependent Claim
22 words
A circuit pin as in claim 2 wherein each of said fins extends perpendicularly away from one side of the first portion.
Claim 5
Dependent Claim
39 words
A circuit pin as in claim 2 wherein the fins of each pair of fins extend toward each other so that the distance between said edges of each pair of fins is less than the distance between said corners.
Claim 6
Dependent Claim
74 words
A square metal circuit pin for mounting in a hole in a circuit panel including a hole-engaging portion of generally H-shaped cross section as taken in a plane perpendicular to the longitudinal pin axis, the legs at each end of the H defined by a pair of longitudinally extending collapsible fins whereby upon insertion of the pin into a circuit panel the fins at each end of the H are collapsed toward each other.
Claim 7
Dependent Claim
74 words
A square metal circuit pin for mounting in a hole in a circuit panel including a hole-engaging portion of generally H-shaped cross section as taken in a plane perpendicular to the longitudinal pin axis, the legs at each end of the H defined by a pair of longitudinally extending collapsible fins whereby upon insertion of the pin into a circuit panel the fins at each end of the H are collapsed toward each other.
Claim 8
Dependent Claim
25 words
A circuit board pin as in claim 5 wherein the legs at each end of the H are flat and generally parallel to each other.
