Abstract
A low insertion force compliant pin is provided for solderless connection to a printed circuit board in which the pin is provided with an enlarged contact portion, a reduced-diameter shank, and one or more slots through the contact portion and the shank such that when the pin is inserted into a solder plated-through hole in the board, the contact portion is compressed on itself, thereby to provide a spring-biased contact to the interior plated wall of the hole in the board. The compliant pin 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 and the diameter of the enlarged contact portion. The distal end of the pin is provided with a connector body, a solder lug, a wire wrap pin or other termination device so that the compliant pin forms one part of an electrical interconnection system for connection to the plated-through holes of the board.
