Abstract
A printed circuit contact system for use in high speed digital applications includes a generally tapered slotted socket made of beryllium copper or other conductive spring material. The socket has a wave-like configuration which forms a series of outer contact portions which alternate with increasingly smaller inner contact portions. Insertion of an appropriately dimensioned pin through the socket causes engagement of the pin with at least one of the inner contact portions to radially expand the socket and force adjoining outer contact portions to abut against a sleeve lining a hole in a printed circuit board into which the socket is inserted. Expansion of the socket provides at least one portion thereof which is always under optimum load, assuring proper retention and physical and electrical contact over extended periods.
