ABSTRACT:
An electronic oscillator wafer crystal (42, 54) mounting assembly (10, 48) includes an insulating thermoplastic mounting block (12) with top and bottom faces (16, 18). Three terminals (22, 50), radially spaced at 90 degrees with respect to each other around the center of the block have shank segments (24) pressed into receiving apertures (18) in the bottom face. Fingers (26) of the terminals extend around the edge of the block to hold the crystal spaced from, and closely adjacent to the top face by supporting it at a perimeter portion on a step-shaped crystal support segment (36) of the finger. A segment (30) of the fingers adjacent and parallel to the bottom face is adapted for conductive attachment to a circuit.
