Abstract
Abstract A circuit board contact is provided comprising a mounting portion and a solid, uniform cross section segment at each end of the mounting portion. The mounting portion includes three fins extending along a length thereof. Each fin includes an interior edge adjacent a central longitudinal axis of the mounting portion. The edges of the fins are separated along their length to provide the fins spring properties for retention of the mounting portion in a hole in a circuit board. Also provided is a method of inserting a pin in a hole in a circuit board comprising inserting a mounting portion of a contact in a hole in a ciruit board, supporting an end of the contact, and compressing the other end of the contact to expand the mounting portion and provide an interference fit in the hole.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
107 words
An elongated circuit board contact including a deformed mounting portion for insertion in a hole in a circuit board and a solid, uniform cross section segment at each end of the mounting portion, said segments having substantially the same cross section, said mounting portion consisting of a radial fin having an edge adjacent the longitudinal axis of the contact and a pair of fins laterally offset and extending in the opposite direction from the radial fin, each laterally offset fin having an edge adjacent said edge of the radial fin, each fin extending lengthwise of the mounting portion and being joined at its ends to said segments.
Claim 2
Dependent Claim
107 words
An elongated circuit board contact including a deformed mounting portion for insertion in a hole in a circuit board and a solid, uniform cross section segment at each end of the mounting portion, said segments having substantially the same cross section, said mounting portion consisting of a radial fin having an edge adjacent the longitudinal axis of the contact and a pair of fins laterally offset and extending in the opposite direction from the radial fin, each laterally offset fin having an edge adjacent said edge of the radial fin, each fin extending lengthwise of the mounting portion and being joined at its ends to said segments.
Claim 3
Dependent Claim
29 words
A contact as recited in claim 1, each fin additionally including a rounded outer edge located on the locus of a circle having said longitudinal axis as its center.
Claim 4
Dependent Claim
22 words
A contact as recited in claim 2, the outer edges of the laterally offset fins being flared and diverging from each other.
Claim 5
Dependent Claim
21 words
A contact as recited in claim 1, each segment at the end of said mounting portion comprising a circuit board pin.
Claim 6
Dependent Claim
142 words
An elongated circuit board contact including a mounting portion adapted for insertion in a hole in a circuit board and a solid, uniform cross section segment at each end of the mounting portion, said segments having substantially the same cross section, said mounting portion consisting of a radial fin including a pair of spaced sides, an outer edge, and an interior edge adjacent the longitudinal axis of the contact and a pair of fins laterally offset and extending in the opposite direction from said radial fin, each laterally offset fin including a pair of spaced sides, and outer edge, and an interior edge adjacent the interior edge of said radial fin, the interior edges of said fins being closely spaced and extending lengthwise of the mounting portion substantially parallel with each other, each fin being joined at its ends to said segments.
Claim 7
Dependent Claim
142 words
An elongated circuit board contact including a mounting portion adapted for insertion in a hole in a circuit board and a solid, uniform cross section segment at each end of the mounting portion, said segments having substantially the same cross section, said mounting portion consisting of a radial fin including a pair of spaced sides, an outer edge, and an interior edge adjacent the longitudinal axis of the contact and a pair of fins laterally offset and extending in the opposite direction from said radial fin, each laterally offset fin including a pair of spaced sides, and outer edge, and an interior edge adjacent the interior edge of said radial fin, the interior edges of said fins being closely spaced and extending lengthwise of the mounting portion substantially parallel with each other, each fin being joined at its ends to said segments.
Claim 8
Dependent Claim
30 words
A contact as recited in claim 5, the outer edge of each fin being rounded and lying on the locus of a circle having said longitudinal axis as its center.
Claim 9
Dependent Claim
29 words
A contact as recited in claim 6, the outer edge of each laterally offset fin being flared and diverging from the outer edge of the other laterally offset fin.
Claim 10
Dependent Claim
21 words
A contact as recited in claim 5, each segment at the end of said mounting portion comprising a circuit board pin.
