ABSTRACT:
A cathode eyelet has its cathode receiving end formed in an elliptical cross-section. Pressure on the long axis opens the short axis to a dimension large enough to admit the cathode. Removal of the pressure allows the sides of the ellipse defined by the short axis to collapse and frictionally retain the cathode in position until it is welded to the eyelet.
