Abstract
Packaging for an electrical instrument wherein the electrical field is to be contained in a metal card cage and the card cage enveloped in a plastic shell. Fastening towers or stems are molded in the base portion of the plastic shell and key slotted windows in the card cage drop over the tower and slid under a ledge of the tower to secure the card cage to the base. Main interface circuit boards having keyslots are adapted to interfit the protruded end of the fastening towers. Biased locking lugs enter the slots in the 'seated' or 'home' positions of both the card cage and circuit board to interlock the three components all without separate fasteners and with a minimum of time and effort.
