Abstract
A new electrical cryogenic connector system employs two printed circuit board type mating connectors (,&,), each containing a plurality of plated-on metal lines (,&,) running along the respective circuit boards in parallel, with the plated-on onmetal lines on at least one of the connectors being of Beryllium Copper material. The ends of the series of Beryllium Copper lines on one of the complementary circuit boards is formed into a pointed spring finger that is pointed toward the opposed circuit board. With the two boards sandwiched and pressed together with their plated on metal lines directly in line with and facing one another, the spring fingers compress and, under the spring force created by that compression, the spring fingers engage and maintain positive electrical contact with the corresponding conductor traces on the opposed circuit board. Ancillary to the described connector, a new method for constructing an electrical connector is also presented.
