ABSTRACT:
The invention relates to a base for a cartridge lamp of the type having at least one filament mounted on filament support legs extending through a seal of the bulb. According to the invention, a plug member has terminals affixed thereto for mounting the filament support legs. The plug member is adapted for keyed insertion into an opening. The terminals extend beyond the plug surface to form tangs which act as clamping fingers. The tangs also serve for contacting the connecting leads after the plug member has been rotated into a locking position.
