Abstract
The present inventive concept provides a method for manufacturing a filament including the steps of inserting and bonding an electrode having a desired length into a through-hole of a plate-shaped base to form a first part; bonding a wire having a desired length to one surface of a plate-shaped disc to form a second part; and bonding the electrode of the first part and the wire of the second part to form a filament, a filament manufactured by said method, and an X-ray tube having said filament.
Claims5
An X-ray tube comprising:
- a filament configured to emit electrons by the supply of power;
- a target configured to receive the electrons from the filament and emit X-rays;
- a body configured to seal the filament and the target while facing each other;
- and
- a cap configured to emit heat in close contact with the target,
- wherein the filament includes:
- a plate-shaped base made of a ceramic material;
- two electrodes made of a metal material, each passing through and bonded to the base, wherein upper portions of the two electrodes are bent to face each other;
- a wire connected to the bent upper portions of the two electrodes;
- and
- a plate-shaped disc connected to the wire,
- wherein the base is larger in size and thicker than the disk, and each of the electrodes has a greater width than the wire.
