ELECTRIC DISCHARGE TUBE, FERRULE, AND ILLUMINATING DEVICE, DISPLAY, AND TV RECEIVER WITH SAID DISCHARGE TUBE

摘要

A conductive ferrule 50 is provided on an end portion of a glass tube 40. The ferrule 50 includes a body that is to be mounted to the outer circumference of the glass tube 40 and has a contact portion 52 to be electrically conductively fixed to a relay connector 14 (or a bearing device). Further included is a conductive part 57 that extends from the body 51 so as to have elastic contact with an outer lead 42. The outer lead 42 will not be under load due to the weight of the discharge tube 15, but the conductive part 57 solely has elastic contact therewith. Thus, stress concentration on the outer lead 42 can be prevented.
