1. Field of the Invention
The present invention relates to an X-ray source in which an X-ray tube and its power supply are integrated with each other, and a nondestructive inspection apparatus comprising an X-ray generator incorporating the X-ray source therein.
2. Related Background Art
FIG. 1 is a vertical sectional view showing the internal structure of the X-ray source in accordance with a conventional example;
FIG. 2 is an exploded perspective view showing the overall structure of the X-ray source in accordance with an embodiment of the present invention;
FIG. 3 is a vertical sectional view showing the internal structure of the X-ray source in accordance with the embodiment;
In the following, embodiments of the X-ray source in accordance with the present invention will be explained with reference to the drawings. Among the drawings referred to, FIG. 2 is an exploded perspective view showing the overall structure of the X-ray source in accordance with an embodiment, whereas FIG. 3 is a vertical sectional view showing the internal structure of the X-ray source in accordance with this embodiment.
As shown in FIGS. 2 and 3, the X-ray source 1 in accordance with the first embodiment comprises a power supply 2 having a structure in which a high-voltage generating part 2B, a high-voltage line 2C, a socket 2D, etc. (see FIG. 2) are molded in an insulating block 2A made of an epoxy resin; a first planer member 3 disposed on the upper face side of the insulating block 2A depicted on the upper face side in the drawing; a second planar member 4 disposed on the lower face side of the insulating block 2A; four fastening spacer members 5 interposed between the first planer member 3 and second planar member 4; and an X-ray tube 7 secured onto the first planar member 3 by way of a metallic tubular member 6.
The insulating block 2A of the power supply 2 is shaped like a rectangular column with substantially square upper and lower faces parallel to each other, whereas the cylindrical socket 2D connected to the high-voltage generating part 2B by way of the high-voltage line 2C is disposed at the center part of the upper face. An annular wall 2E arranged concentrically with the socket 2D projects from the upper face of the insulating block 2A. The peripheral face of the insulating block 2A is coated with conductive paint 8 for attaining the GND potential (ground potential).
