Abstract
Abstract A low insertion force compliant pin (20) is provided for solderless connection to a printed circuit board (52) in weich the pin (20) is provided with an enlarged contact portion (28), a reduced-diameter shank (32), and one or more slots 34) through the contact portion (28) and the shank (32) such mat when the pin (20) is inserted into a solder plated-through hole (50) in the board, the contact portion (28) is compressed on itself, thereby to provide a spring-biased contact to the interior plated wall (56) of the hole (50) in the board (52). The compliant pin (20) also provides anti-overstress protection by compressing on itself. The compliant pin is adapted for use with a number of different hole sizes, with spring bias tension being controlled by the elasticity of the pin material and the length of the slot or slots (34) and the diameter of the enlarged contact portion (28). The distal end (24) of the pin is provided with a connector body. a solder lug, a wire wrap pin or other termination devices so that the compliant pin forms one part of an electrical interconnection system for connection to the plated-through holes of the board.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
184 words
A low insertion force electrical interconnection pin (20) adapted for use with plated-through holes ' (50) of varying size in a printed wiring board (52) to provide good electrical connection between the leads of externally mounted components or wires and the printed wiring board holes, characterized in that said pin (20) comprises: an enlarged diameter proximal end (22) and a reduced diameter distal end (24), said distal end having a shaft (32) and means (40) at the end of said shaft for making electrical contact to said leads or wire; a portion of said shaft (32) and said enlarged diameter proximal end (22) having a slot (34) therethrough running from one side of said pin to the other for dividing said proximal end (22) into two spaced apart portions (28a, 28b), said slot (34) providing two spaced apart spring members in the form of opposing shaft portions (32a, 32b), with the spring moment applied to said spaced apart proximal end portions (28a, 28b) and being dependent on the elasticity of the pin material and the length of the slot (34) in said shaft (32).
