Abstract
Official abstract text for this publication.
According to one embodiment, an X-ray tube includes a cathode, an anode target and an envelope. The cathode includes an insulating member, a conductive line, a pin assembly, a filament, a focusing electrode, and a terminal assembly. The conductive line is formed on the insulating member. The pin assembly includes a pin and a first sleeve. The terminal assembly is fixed to the insulating member, is supporting the filament, and is electrically connecting the filament to the conductive line.
First claim
Opening claim text (preview).
What is claimed is: 1 . An X-ray tube comprising: a cathode including: an insulating member; a conductive line formed of metal and formed on the insulating member; a pin assembly including a pin having a conductive property and a first sleeve which has a conductive property, is fixed to the insulating member, guides the pin, is fixing the pin, and electrically connects the pin to the conductive line; a filament configured to emit electrons; a focusing electrode configured to focus the electrons emitted from the filament; and a terminal assembly having a conductive property, fixed to the insulating member, supporting the filament, and electrically connecting the filament to the conductive line; an anode target with which the electrons emitted from the cathode collide to generate X-rays; and an envelope which accommodates the insulating member, the conductive line, the first sleeve, the filament, the focusing electrode, the terminal assembly and the anode target, and to which the pin is attached. 2 . The X-ray tube of claim 1 , wherein the terminal assembly includes: a terminal having a conductive property and supporting the filament; and a second sleeve which has a conductive property, is fixed to the insulating member, guides the terminal, is fixing the terminal, and electrically connects the terminal to the conductive line. 3 . The X-ray tube of claim 1 , wherein the insulating member includes a groove portion in which the filament is provided, and a hole portion which communicates with the groove portion and in which the terminal assembly is located, and the focusing electrode is formed in the groove portion. 4 . The X-ray tube of claim 1 , wherein the pin is connected to the first sleeve by welding.
