Abstract
Abstract A method and apparatus for interconnecting electronic circuit boards through the use of twisted wire jumpers which are formed from multifilament wire and which have enlarged bird cages formed along the pins. The pins are drawn through a stack of circuit boards to position the cages in contact with interconnection aperture located in the printed circuit boards. The frictional engagement of the cages in the apertures provides both electrical interconnection of, and mechanical coupling between the printed circuit boards. This application is a division of co pending patent application Her. No. 07/347,507, filed May 4, 1989, now U.S. Pat. No. 5,014,419, issued May 14, 1991, U.S. Pat. application Ser. No. 07/347,507 was a continuation-in-part of application Ser. No. 07/053,142, filed May 21, 1989, now U.S. Pat. No. 5,054,192, issued Oct. 8, 1991.
