[0002] Since high voltage is required for X-ray generators to generate X-rays, all X-ray devices require high voltage related designs, among which high voltage insulation design is one of the links.

[0003] The existing high-voltage insulation structure design is different for each manufacturer, and the high-voltage insulation effect reflected by the high-voltage insulation structure design is also different. Since the insulation reinforcement needs to be carried out in a limited space for the high-voltage potential in the space, the X-ray device in the prior art is integrated in the box. When the X-ray device is working, high voltage will also be generated at both ends of the X-ray device, and the whole device will generate high voltage and flashover discharge to the external environment or between itself, so that the box will be charged, resulting in the staff being unable to touch the box, which is easy to cause safety hazards.

[0004] In order to make the whole equipment generate high voltage without flashover discharge to the external environment or between itself, the idea of ​​existing insulation design is basically to increase the box, that is, to increase the creepage distance between the X-ray device and the box. The existing technology ignores the space utilization while increasing the insulation design margin. In addition, due to the consideration of the insulation design margin, more expensive insulation materials are usually used, which greatly increases the volume and production cost of the X-ray device.

[0005] Therefore the prior art needs to be improved and enhanced. Utility Model Content

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the split-type voltage doubling circuit insulation protection device for an X-ray device provided by the utility model comprises two oppositely arranged insulating protective shells 1, which are fixed by an insulating plate 2, so that a mounting cavity 4 for mounting the voltage doubling circuit board 3 is formed between the insulating protective shells 1 and the insulating plate 2, and a side panel 5 is provided on one side of the two insulating protective shells 1, and a mounting position 6 for mounting an X-ray tube device (not shown in the figure) is provided between the two side panels 5.

[0035] It can be understood that the X-ray tube device and the split voltage-doubling circuit insulation protection device are integrated in the box after assembly. When the X-ray tube device is working, high voltage will be generated at both ends of the voltage-doubling circuit board 3 and the X-ray tube device. Under the blocking of the insulating protective shell 1 and the side plate 5, the overall device generates high voltage without flashover discharge to the external environment or between itself, that is, the box will not be charged, avoiding safety hazards.

[0036] Compared with the prior art, the insulating protective shell 1 can greatly enhance the creepage distance advantage between the voltage multiplier circuit board 3 and the box body. The X-ray tube device is installed in the installation position 6 to fully utilize the space, while reducing the design volume of the high-voltage insulation and effectively reducing the production cost.

[0037] Furthermore, if Figure 1 and Figure 2 As shown, the side plate 5 is provided with an insulating cover plate 7, and the insulating cover plate 7 is provided with a notch 8 for facilitating the installation of a wiring harness. When the X-ray tube device is installed in the installation position 6, wiring harnesses will be led out from both ends of the X-ray tube device, and the notch 8 facilitates the leading out of the wiring harness. The insulating cover plate 7 can increase the insulation design margin at the notch 8, play a blocking role, and achieve the effect that the overall device generates a high voltage without causing flashover discharge to the external environment or between itself.

[0038] Furthermore, if Figure 1 and Figure 2 As shown, the insulating cover plate 7 is provided with a mounting hole 21, and the insulating cover plate 7 is fixed to the side plate 5 through the mounting hole 21. The mounting hole 21 enables the insulating cover plate 7 to be fixed to the side plate 5, so as to facilitate the mounting and fixing of the insulating cover plate 7 to the side edge.

[0039] Furthermore, if Figure 2 , Figure 3 and Figure 4As shown, the cross-sections of the insulating cover plate 7 and the side plate 5 are both L-shaped. It can be understood that the insulating cover plate 7 and the side plate 5 are assembled inverted with each other, so that a "mouth"-shaped assembly structure is formed between the insulating cover plate 7 and the side plate 5, which effectively increases the insulation protection effect.

[0040] Furthermore, if Figure 4 As shown, the insulating housing 1 is provided with a protective cavity 10, the protective cavity 10 is sleeved at the end of the voltage doubler circuit board 3, and the voltage doubler circuit board 3 is suspended in the protective cavity 10. It can be understood that the voltage doubler circuit board 3 is suspended in the protective cavity 10, which can greatly enhance the creepage distance advantage in the high voltage design and play a better insulation protection effect.

[0041] Furthermore, if Figure 3 As shown, the insulating plate 2 includes a first insulating plate 11 and a second insulating plate 12. The first insulating plate 11 is provided with a first fixing hole 9. The first insulating plate 11 is fixed to one side of the two insulating protective shells 1 with screws through the first fixing hole 9, and the second insulating plate 12 is nested with the other side of the two insulating protective shells 1.

[0042] It should be noted that after the voltage doubling circuit board 3 is fixed to other components in the box, the second insulating plate 12 is nested with the other side of the two insulating shells 1, so that during the assembly process, the second insulating plate 12 and the insulating shell 1 can be pre-installed. The technical solution of the present application can be assembled and disassembled in a split form through the mutual nesting design of the first insulating plate 11, the second insulating plate 12, and the insulating shell 1, and the installation process is simple and convenient.

[0043] Preferably, if Figure 4 , Figure 5 and Figure 6 As shown, a first snap-in 13 and a second snap-in 14 are respectively provided on one side and the bottom of the second insulating plate 12, a first clamping platform 15 clamped to the first clamping platform 13 is provided at the connection between the insulating protective shell 1 and the side plate 5, and a second clamping platform 16 clamped to the second clamping platform 14 is provided at the bottom of the insulating protective shell 1.

[0044] It can be understood that the second insulating plate 12 can be inserted into the insulating protective shell 1 by the first clamping port 13 being clamped with the first clamping platform 15 and the second clamping port 14 being clamped with the second clamping platform 16 .

[0045] Furthermore, if Figure 5 and Figure 6As shown, a slide groove 17 is provided on the second insulating plate 12, and a slide rail 18 is provided on the insulating protective shell 1. The slide groove 17 and the slide rail 18 are slidably arranged to make the engagement between the second insulating plate 12 and the insulating protective shell 1 more stable.

[0046] It can be understood that the nesting between the second insulating plate 12 and the insulating protective shell 1 is achieved through a three-layer clip-on structure, namely, the first clip 13 is clipped with the first clip platform 15, the second clip 14 is clipped with the second clip platform 16, and the slide groove 17 is clipped with the slide rail 18, so that the installation between the second insulating plate 12 and the insulating protective shell 1 is more stable.

[0047] Furthermore, if Figure 6 As shown, a second fixing hole 19 is provided on the second insulating plate 12, and the second insulating plate 12 is fixed to the insulating shell 1 by screws through the second fixing hole 19. The second fixing hole 19 can enhance the installation stability between the second insulating plate 12 and the insulating shell 1.

[0048] Furthermore, if Figure 1 As shown, both sides of the top of the first insulating plate 11 and the second insulating plate 12 are provided with mounting grooves 20 for installing insulating baffles. It should be noted that, according to the results of actual tests, other insulating baffles can be selectively installed in the mounting grooves 20 to increase the insulation design margin, so as to achieve the effect that the overall device generates high voltage without flashover discharge to the external environment or between itself.

[0049] In summary, the utility model provides a split-type voltage-doubling circuit insulation protection device for an X-ray device, wherein the insulation cover can increase the insulation design margin at the notch, play a blocking role, and achieve the effect that the overall device generates high voltage without causing flashover discharge to the external environment or between itself. The cross-sections of the insulation cover and the side plate are both L-shaped, so that a "mouth"-shaped assembly structure is formed between the insulation cover and the side plate, which effectively increases the insulation protection effect. The voltage-doubling circuit board is suspended in the protection cavity, which can greatly enhance the creepage distance advantage in the high-voltage design, and has a better insulation protection effect. During the assembly process, the second insulation board and the insulation shell can be pre-installed. According to the utility model, through the insulation shell, the creepage distance advantage between the voltage-doubling circuit board and the box body can be greatly enhanced, and the X-ray tube device can be installed in the installation position to fully utilize the space, while reducing the design volume of the high-voltage insulation, and effectively reducing the production cost.

The above-mentioned specific implementation methods are merely illustrative and not restrictive.
