Abstract

This device provides registration pins mounted to yield in any radial direction and spaced to receive printed circuit panels having corresponding registration holes. As in A, base 1 has fastened in it pointed rods 2, provided with collars 3 near their upper ends. Printed circuit card 4 containing locating holes 5 is adapted to engage the rods to properly position such card on the holder. The length and diameter of rods 2 are selected to be slightly resilient so as to exert a self-balancing effect to position card 4. The latter is located where strain-energy is a minimum. Alternate methods for achieving the same self-balancing effect are shown at B in which a plurality of springs 6 resiliently support a shorter rod 2 or as at C where the shorter rod 2 is mounted in rubber or elastomer 7.
