Abstract
Abstract A terminal pin, having a compressed portion the cross section of which is roughly V-shaped, has a pair of arms and a pair of convex contact edges with a concave trail between the convex contact edges. The pair of arms have a uniform thickness and are deformed inwardly when pressed into a through hole defined in a PCB. After being pressed into the through hole, the compressed portion contacts the internal surface of the through hole at four locations, namely, at a pair of external surfaces provided at the ends of the pair of arms and the pair of convex contact edges.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
88 words
A terminal pin comprising: (a) a post portion; (b) a compressible portion extending from said post portion; (c) said compressible portion being generally V-shaped and formed by a pair of arms and a bottom; (d) said bottom having a cross-sectional thickness greater than said arms and having a pair of convex contact edges on an outer surface thereof; (e) said arms being elastically inwardly deformable when the pin is pressed into a through hole, whereby ends of said arms and said convex contact edges contact the through hole.
Claim 2
Dependent Claim
88 words
A terminal pin comprising: (a) a post portion; (b) a compressible portion extending from said post portion; (c) said compressible portion being generally V-shaped and formed by a pair of arms and a bottom; (d) said bottom having a cross-sectional thickness greater than said arms and having a pair of convex contact edges on an outer surface thereof; (e) said arms being elastically inwardly deformable when the pin is pressed into a through hole, whereby ends of said arms and said convex contact edges contact the through hole.
Claim 3
Dependent Claim
14 words
The pin of claim 1 including a concave surface between said convex contact edges.
Claim 4
Dependent Claim
21 words
The pin of claim 1 wherein the ends of said arms are angled to permit surface contact with the through hole.
Claim 5
Dependent Claim
14 words
The pin of claim 1 wherein said bottom has a generally flat inner surface.
Claim 6
Dependent Claim
13 words
The pin of claim 1 wherein said arms have a generally uniform thickness.
Claim 7
Dependent Claim
43 words
The pin of claim 1 including a concave surface between said convex contact edges and said arms having a generally uniform thickness, said bottom having a generally flat inner surface and said arms being angled to permit surface contact with the through hole.
Claim 8
Dependent Claim
16 words
The pin of claim 1 wherein the bottom crosssectional thickness is substantially greater than said arms.
Claim 9
Dependent Claim
113 words
A terminal pin comprising: (a) a post portion; (b) a compressible portion extending from said post portion; (c) said compressible portion being generally V-shaped and formed by a pair of arms having a generally uniform thickness and a bottom; (d) said bottom having a cross-sectional thickness substantially greater than said arms and having a pair of convex contact edges on an outer surface thereof; (e) said bottom including a concave surface between said convex contact edges and having a generally flat inner surface; (f) said arms being elastically inwardly deformable when the pin is pressed into a through hole, whereby ends of said arms and said convex contact edges contact the through hole.
Claim 10
Dependent Claim
113 words
A terminal pin comprising: (a) a post portion; (b) a compressible portion extending from said post portion; (c) said compressible portion being generally V-shaped and formed by a pair of arms having a generally uniform thickness and a bottom; (d) said bottom having a cross-sectional thickness substantially greater than said arms and having a pair of convex contact edges on an outer surface thereof; (e) said bottom including a concave surface between said convex contact edges and having a generally flat inner surface; (f) said arms being elastically inwardly deformable when the pin is pressed into a through hole, whereby ends of said arms and said convex contact edges contact the through hole.
