Problems solved by technology

That is, the high-voltage cable has very little bending freedom due to its high-voltage characteristics and structure, and care must be taken to prevent disasters caused by leakage in the connection to the X-ray generating device. Carry out regular maintenance, which is a strong excessive burden on the operator or user
Furthermore, the weight of the high-voltage cable is also a factor that further increases the burden on the operator.
[0004] In addition, the X-ray generating device that the power supply part is molded with epoxy resin is disclosed in the Japanese Patent Opening No. 58-14499, but this X-ray generating device is a sealed type, and the method of generating a vacuum by a vacuum pump is not possible. Replacing the Cathode Form Device

Embodiment Construction

[0015] Next, an ideal embodiment of the open X-ray generator according to the present invention will be described in detail with reference to the accompanying drawings.

[0016] As shown in FIG. 1 , this X-ray generator 1 is an open type. Unlike a disposable closed type, it can generate a vacuum state arbitrarily, and can carry out the filament part F or the target 10 as consumables. replacement. This X-ray generator 1 has a cylindrical stainless steel cylindrical part 2 that is in a vacuum state during operation. The cylindrical portion 2 is divided into two parts by a fixed portion 3 positioned on the lower side and a detachable portion 4 positioned on the upper side, and the detachable portion 4 is attached to the fixed portion 3 via a hinge portion 5 . Therefore, when the detachment part 4 is turned in a sideways state via the hinge part 5, the upper part of the fixing part 3 can be opened, and the filament part (cathode) F stored in the fixing part 3 can be replaced.

Abstract

According to the open type X-ray generating device (1) of the present invention, in order to improve usability, the high-voltage generating part (15) and the grid connection wiring (32) that provide high voltage (for example, 160KV) are used to provide high voltage (for example, 160KV) without high-voltage cables. ) and the molded power supply part (14) of the filament connection wiring (33), by fixing the molded power supply part (14) to the base end side of the cylindrical part (2), the integration of the power supply is realized. In this way, by enclosing the high voltage generating part (15), the grid connection wiring (32) and the filament connecting wiring (33) in the resin mold, the degree of freedom in the structure of the high voltage generating part (15) or wiring can be further improved. (32, 33) degrees of freedom to bend.

Description

technical field [0001] The present invention relates to an open type X-ray generator, and more particularly to an open type X-ray generator in which a consumable filament part can be replaced by vacuum suction of a vacuum pump. Background technique [0002] Conventionally, Japanese Patent Application Publication No. 10-503618 is known as a technique in this field. In the X-ray generating device described in this gazette, the electron beam emitted from the cathode is emitted with the focus formed on the target by the electromagnetic action of the coil, and then the X-ray beam is irradiated to the object to be inspected. Here, since the X-ray generating device operates at a very high voltage of 160KV, it is necessary to additionally equip a large high-voltage power supply device, which is connected to the X-ray generating device via a high-voltage cable. [0003] However, since the high-voltage power supply device driving the X-ray generator is constructed to generate extreme...
