Abstract
Cathode structure for cathode ray tube comprising an eyelet in two separate parts positioned such that one of the parts covers, in the longitudinal direction and at least partially, the second part. The two parts are linked to each other at the shouldered ends.This structure reduces the heat losses of the cathode and reduces its consumption while it is operating.
