Abstract
A wafer type tube base is secured to a stem structure of an electron tube. The base includes a cup which fits over an exhaust tubulation of the stem and a wafer flange which extends radially outward from the open end of the cup and abuts the stem wall. The flange has an array of apertures for receiving an array of stem conductors therethrough. An adapter is provided for converting the wafer-type base to a pin-protector type base. The adapter comprises a hollow cylindrical member having a plurality of longitudinally extending ribs on its outer surface. The adapter telescopes over the exhaust tubulation cup and receives the stem conductors in the grooves between the ribs. Means for interlocking the adapter to the wafer base comprises a pair of openings in the cylindrical wall of the cup and a pair of inwardly projecting fingers at an end of the adapter which are adapted to be received in the openings and are sized to engage the cup wall in a frictional snap fit.
