Abstract
Abstract A terminal pin is designed for insertion through a hole in a printed circuit board and for soldering to a circuit trace on the board. The pin includes a terminal portion at one end and a solder tail portion at an opposite end, with the neck portion therebetween. The neck portion has a reduced cross-sectional dimension versus that of the terminal portion and the solder tail portion to increase the flexibility of the pin at the neck portion. The neck portion provides an area of flexibility adjacent the area of soldering the pin to the printed circuit board.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
113 words
A terminal pin for insertion through a hole in a printed circuit board and for soldering to a circuit trace on the board, comprising a terminal portion at one end of the pin, a solder tail portion at an opposite end of the pin and a neck portion therebetween, the terminal portion of the solder tail portion having substantially the same cross-sections dimensions, and the neck portion having a reduced cross-sectional dimension forming a square in a plane perpendicular to the longitudinal axis of the pin to increase the flexibility of the pin substantially the same in all directions radial to the pin in the area of soldering to the printed circuit board.
Claim 2
Dependent Claim
113 words
A terminal pin for insertion through a hole in a printed circuit board and for soldering to a circuit trace on the board, comprising a terminal portion at one end of the pin, a solder tail portion at an opposite end of the pin and a neck portion therebetween, the terminal portion of the solder tail portion having substantially the same cross-sections dimensions, and the neck portion having a reduced cross-sectional dimension forming a square in a plane perpendicular to the longitudinal axis of the pin to increase the flexibility of the pin substantially the same in all directions radial to the pin in the area of soldering to the printed circuit board.
Claim 3
Dependent Claim
21 words
The terminal pin of claim 1 wherein the terminal portion and the tail portion of the pin are rectangular in cross-section.
Claim 4
Dependent Claim
16 words
The terminal pin of claim 1 wherein said neck portion of the pin has concave sides.
Claim 5
Dependent Claim
21 words
The terminal pin of claim 3 wherein the terminal portion and the tail portion of the pin are rectangular in cross-section.
Claim 6
Dependent Claim
85 words
A terminal pin for insertion through a hole in a printed circuit board and for soldering to a circuit trace at a solder joint on one side of the board, the pin having a reduced cross-sectional portion forming a square in a plane perpendicular to the longitudinal axis of the pin located to provide a pivot area to increase the flexibility of the pin substantially the same in all directions radial to the pin at said portion and thereby isolating stresses from the solder joint.
Claim 7
Dependent Claim
85 words
A terminal pin for insertion through a hole in a printed circuit board and for soldering to a circuit trace at a solder joint on one side of the board, the pin having a reduced cross-sectional portion forming a square in a plane perpendicular to the longitudinal axis of the pin located to provide a pivot area to increase the flexibility of the pin substantially the same in all directions radial to the pin at said portion and thereby isolating stresses from the solder joint.
Claim 8
Dependent Claim
22 words

Claim 10
Dependent Claim
13 words
The terminal pin of claim 7 wherein said generally uniform cross-section is rectangular.
Claim 11
Dependent Claim
13 words
The terminal pin of claim 6 wherein said generally uniform cross-section is rectangular.
Claim 12
Dependent Claim
79 words
A terminal pin for mounting on an electrical connector and extending therefrom for soldering to a printed circuit board at a solder joint, the pin having a reduced cross-sectional portion forming a square in a plane perpendicular to the longitudinal axis of the pin between the connector and the solder joint to increase the flexibility of the pin substantially the same in all directions radial to the pin at said portion and thereby isolating stresses from the solder joint.
Claim 13
Dependent Claim
79 words
A terminal pin for mounting on an electrical connector and extending therefrom for soldering to a printed circuit board at a solder joint, the pin having a reduced cross-sectional portion forming a square in a plane perpendicular to the longitudinal axis of the pin between the connector and the solder joint to increase the flexibility of the pin substantially the same in all directions radial to the pin at said portion and thereby isolating stresses from the solder joint.
Claim 14
Dependent Claim
22 words
