[0026] The voltage multiplier assembly and X-ray high voltage generator provided by this invention have the following advantages:

[0027] 1. This invention provides a voltage multiplier assembly, which is adapted to be installed inside an external enclosure. The low-voltage side of the voltage multiplier assembly is fixed to the inner wall of the enclosure so that the voltage multiplier assembly is suspended inside the enclosure. The voltage multiplier assembly includes a plurality of voltage multiplier plate modules, a plurality of insulating plates, a high-voltage socket, and a transformer. Each voltage multiplier plate module includes a voltage multiplier plate and a voltage multiplier plate equalizing ring, the voltage multiplier plate equalizing ring being sleeved around the periphery of the voltage multiplier plate.

[0028] This voltage multiplier assembly is divided into several voltage multiplier modules according to the total number of voltage multiplication levels. These modules are electrically connected via banana plugs or other convenient connection methods. Each voltage multiplier module is equipped with a corresponding voltage equalization ring. This structure effectively divides the high voltage into several potential levels, with consistent voltage levels within each module. By controlling the electric field distortion caused by component pins and other sharp points in each module, and by separately controlling the electric field strength between each module, the electric field equalization of the entire voltage multiplier assembly can be effectively and conveniently controlled, enabling miniaturized product design. Furthermore, by fixing the low-voltage side of the voltage multiplier assembly to the inner wall of the housing, the assembly is suspended within the housing. This maximizes the creepage distance between the high-voltage side and the low-potential side within a limited space, further facilitating miniaturization.

[0029] 2. This invention provides a voltage multiplier assembly. A high-voltage socket is inserted at the center of the voltage multiplier assembly, moving from the low-voltage side to the high-voltage side. High voltage is introduced from the high-voltage side of the voltage multiplier assembly to the high-voltage socket. Specifically, the voltage is generated by the transformer, multiplied step-by-step through the voltage multiplier assembly from low to high voltage, then transmitted from the high-voltage position to the low-voltage position via the high-voltage socket, and finally through the external housing. A high-voltage cable connects to the high-voltage socket and delivers the voltage to the X-ray tube. This design effectively utilizes the length of the high-voltage socket to arrange the voltage multiplier assembly in the surrounding space, maximizing internal space, increasing the overall power density, and making the structure more compact, facilitating the miniaturization of the high-voltage generator.

[0030] 3. This invention provides a voltage multiplier assembly. One end of the high-voltage socket guide has a guide cavity. During installation, the opening of the guide cavity faces the lowest voltage side of the voltage multiplier module. The high-voltage socket is inserted into the inner end of the voltage multiplier module, which is suitable for insertion into the guide cavity. The high-voltage socket guide has an electrical adapter plate and several spring-loaded female pins. The electrical adapter plate is electrically connected to the spring-loaded female pins, and the electrical adapter plate is electrically connected to the highest voltage multiplier plate in the voltage multiplier module. Several spring-loaded female pins are located at the bottom of the guide cavity for electrical connection with the high-voltage socket, thereby achieving electrical connection between the high-voltage socket and the highest voltage multiplier plate in the voltage multiplier module, enabling wire-free electrical connection of the high-voltage socket.

[0031] 4. This invention provides an X-ray high-voltage generator, which uses a mechanical structure to fix the low-voltage side of the voltage multiplier component to the housing with a single-end cantilever, so that the high-voltage side of the voltage multiplier component is suspended in the transformer oil, avoiding contact between the high-voltage side structural components and surrounding devices, increasing the creepage distance between the high-voltage side and the ground potential, and achieving the design requirements for the creepage distance of the high-voltage side of the product under the premise of effective fixation.

In addition, the technical features involved in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

[0051] Example 1

[0052] This embodiment provides a voltage multiplier component, such as... Figures 1 to 5 As shown, the voltage multiplier assembly includes a voltage multiplier plate module, an insulating plate 3, a high-voltage socket 4, a transformer 5, a filament transformer assembly 6, a high-voltage socket guide 7, and an electrical adapter 8.

[0053] In this embodiment, as Figures 1 to 3 As shown, there are nine voltage multiplier modules. Each voltage multiplier module includes a voltage multiplier plate 1 and a voltage multiplier plate equalizing ring 2, with the equalizing ring 2 sleeved around the periphery of the voltage multiplier plate 1. An insulating plate 3 is provided between two adjacent voltage multiplier modules, and the two adjacent voltage multiplier modules are electrically connected. A high-voltage socket 4 is inserted into all voltage multiplier modules from the low-voltage side to the high-voltage side of the voltage multiplier plate 1. Figure 1 (From left to right), and the end of the high-voltage socket 4 inserted into the voltage multiplier module is connected to the highest voltage side of several voltage multiplier modules ( Figure 1 The rightmost voltage multiplier 1 is electrically connected; the secondary output lead of transformer 5 is connected to the lowest voltage side of several voltage multiplier modules. Figure 1 The leftmost voltage multiplier plate 1 is electrically connected; the electrical adapter 8 is connected to the highest voltage side of the voltage multiplier plate module, and a high voltage equalizing ring 95 and a high voltage socket guide 7 are installed on the electrical adapter 8. The filament transformer assembly 6 includes an insulating cylinder 61 and a filament transformer, with the filament transformer located inside the insulating cylinder 61; each voltage multiplier plate 1 is provided with a filament transformer mounting hole 11, and the filament transformer assembly 6 is configured to pass through the mounting holes in all voltage multiplier plates 1 in sequence, so as to be located inside all voltage multiplier plate modules; each voltage multiplier plate 1 is provided with two filament transformer mounting holes 11 and one high voltage socket mounting hole 12 suitable for the high voltage socket 4 to pass through, and the two filament transformer mounting holes 11 are symmetrically arranged relative to the high voltage socket mounting hole 12.

[0054] The above structure consists of a voltage multiplier module formed by installing voltage multiplier equalizing rings 2 around the voltage multiplier 1. Each voltage multiplier module is then fixed by passing through filament transformer assemblies 6 through filament mounting holes on both sides of the voltage multiplier 1. An insulating plate 3 is placed between adjacent voltage multiplier modules, and adjacent modules are electrically connected using banana-shaped contacts or other electrical connection structures. In use, the voltage multiplier modules can be stacked according to the voltage multiplication requirement, with the highest voltage side among the nine voltage multiplier modules (…). Figure 1 At the rightmost end, install electrical adapter 8. Install a high-voltage equalizing ring 95 and a high-voltage socket guide 7 on electrical adapter 8. The high-voltage socket 4 extends from the low-voltage side of the voltage multiplier plate 1 to the high-voltage side of the voltage multiplier plate 1. Figure 1 Insert the high-voltage socket 4 into all the voltage multiplier modules from left to right, and insert the high-voltage socket 4 into the end of the voltage multiplier module. Figure 1 The high-voltage socket (right end of the 4-pin connector) and the highest voltage side of several voltage multiplier modules ( Figure 1 The rightmost end of the voltage multiplier module) is electrically connected to voltage multiplier 1, and transformer 5 is installed on the lowest voltage side of the nine voltage multiplier modules. Figure 1 The leftmost one), and connect the secondary output lead of transformer 5 to the lowest voltage side voltage multiplier 1 of the nine voltage multiplier modules ( Figure 1 (the leftmost one).

[0055] In some embodiments, the voltage multiplier 1 is potted with epoxy resin, silicone or polyurethane adhesive, the equalizing ring is made of metal or semi-conductive material by injection molding or machining, and the high-voltage electrical adapter 8 is an insulating component with a circuit board arranged on it for high-voltage signal conversion.

[0056] The voltage multiplier assembly provided in this embodiment is divided into several voltage multiplier modules according to the total number of voltage multiplier levels. These modules are electrically connected via banana plugs or other convenient connection structures. Each voltage multiplier module is equipped with a corresponding voltage equalization ring 2. This structure can effectively divide the high voltage into several potential levels. The voltage levels inside each voltage multiplier module are consistent. By controlling the electric field distortion caused by the sharp points of components such as pins in each voltage multiplier module, and by controlling the electric field strength between each voltage multiplier module separately, the electric field equalization control of the entire voltage multiplier assembly can be effectively and conveniently achieved, enabling miniaturized product design.

[0057] The voltage multiplier provided in this embodiment has a large-diameter high-voltage equalizing ring 95 at the highest potential position of the voltage multiplier, which can effectively control the electric field strength at the highest position. This allows the electric field strength to be controlled within a controllable range at a position where the highest potential is close to the external enclosure 91.

[0058] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the filament transformer assembly 6 includes an insulating cylinder 61 and a filament transformer. The filament transformer is located inside the insulating cylinder 61. During installation, the insulating cylinder 61 can be inserted into the filament transformer mounting hole 11 on the voltage multiplier plate 1. The filament transformer assembly 6 operates at low voltage. Figure 1 The leftmost side is the high voltage side, the rightmost side is the low voltage side, the low voltage side is connected to the external control box, and the high voltage side is connected to the high voltage socket 4.

[0059] The voltage multiplier assembly provided in this embodiment has pre-drilled filament transformer mounting holes 11 on both sides of the voltage multiplier plate module. The large filament transformer assembly and the small filament transformer assembly are respectively installed and fixed by passing through the pre-drilled filament transformer holes in the voltage multiplier plate assembly from the low-voltage side to the high-voltage side of the voltage multiplier assembly.

[0060] In this embodiment, the high-voltage socket guide 7 is located on the highest voltage side of the voltage multiplier module, and the high-voltage socket guide 7 is used for electrical connection between the high-voltage socket 4 and the highest voltage side of the voltage multiplier module. Figure 4 As shown, the high-voltage socket guide 7 has a guide cavity at one end. During installation, the opening end of the guide cavity faces the lowest voltage side of the voltage multiplier module. The high-voltage socket 4 is inserted into the voltage multiplier module, and its inner end is suitable for insertion into the guide cavity. The high-voltage socket guide 7 is provided with an electrical adapter plate 71 and several spring contact pins 72. The electrical adapter plate 71 is electrically connected to the spring contact pins 72, and the electrical adapter plate 71 is electrically connected to the highest voltage multiplier plate 1 in the voltage multiplier module. Several spring contact pins 72 are located at the bottom of the guide cavity to electrically connect with the high-voltage socket 4, so as to realize the electrical connection between the high-voltage socket 4 and the highest voltage multiplier plate 1 in the voltage multiplier module, and realize the electrical connection of the high-voltage socket 4 without wiring.

[0061] In this embodiment, the voltage multiplier assembly is adapted to be installed inside the outer housing. The low-voltage side of the voltage multiplier assembly is fixed to the inner wall of the housing so that the voltage multiplier assembly is suspended inside the housing. Specifically, each voltage multiplier plate 1 is respectively fitted and fixed on the insulating cylinder 61, the insulating cylinder 61 is fixed on the end voltage multiplier assembly support plate 96, and the voltage multiplier assembly support plate 96 is mechanically fixed to one side of the housing 961.

[0062] By fixing the low-voltage side of the voltage multiplier assembly to the inner wall of the housing, the voltage multiplier assembly is suspended inside the housing. This allows for both fixation within a limited space and maximizes the creepage distance between the high-voltage side and the low potential, which is beneficial for miniaturization design. The voltage multiplier assembly provided in this embodiment involves inserting the high-voltage socket 4 at the center of the voltage multiplier assembly, from the low-voltage side of the voltage multiplier plate 1 to the high-voltage side. High voltage is introduced from the high-voltage side of the voltage multiplier plate 1 to the high-voltage socket 4. That is, the voltage is generated by the transformer 5, multiplied step-by-step from the low-voltage position to the high-voltage position through the voltage multiplier assembly, then transmitted from the high-voltage position of the voltage multiplier plate 1 to the low-voltage position via the high-voltage socket 4, and then through the outer housing 91. It is then delivered to the X-ray tube via a high-voltage cable connected to the high-voltage socket 4. This mechanism design effectively utilizes the length of the high-voltage socket 4 to arrange the voltage multiplier assembly in the surrounding space, making full use of the internal space, increasing the overall power density of the machine, making the structural design more compact, and facilitating the miniaturization design of the high-voltage generator.

[0063] Example 2

[0064] This embodiment provides an X-ray high-voltage generator. For example... Figure 1 As shown, it includes a housing 91, a housing cover 92, a main insulating cylinder 93, an insulating end cap 94, a fixing assembly, and the voltage multiplier assembly in Embodiment 1.

[0065] like Figure 1 and Figure 6 As shown, the main insulating cylinder 93 has an open end and is fitted around the voltage multiplier module through its open end. The main insulating cylinder 93 is located inside the housing 91, and the insulating end cap 94 is located inside the housing 91 and covers the opposite end of the open end of the main insulating cylinder 93. The fixing assembly includes a voltage multiplier module support plate 96 and a voltage multiplier module mechanical support plate 97. The voltage multiplier module support plate 96 is located between the main insulating cylinder 93 and the side wall of the housing 91 to fix the main insulating cylinder 93. The voltage multiplier module mechanical support plate is connected between the voltage multiplier module support plate 96 and the insulating end cap 94.

[0066] The X-ray high-voltage generator provided in this embodiment is installed by installing the voltage multiplier assembly inside the main insulating cylinder 93. The high-voltage side is shielded and insulated using the end insulating cap 94. Then, the main insulating cylinder 93 is fixed to the side wall of the housing 91 by the voltage multiplier assembly support plate 96, while maintaining a gap between the bottom of the housing 91 and the main insulating cylinder 93. Then, the high-voltage socket 4 is inserted into the voltage multiplier assembly. Finally, the housing cover 92 is installed on the housing 91. Finally, transformer 5 insulating oil is injected into the housing 91 as the insulating medium.

[0067] In this embodiment, the voltage multiplier component is fixed to the inner wall of the housing, thus suspending the component inside the housing. This method of fixing the low-voltage side of the voltage multiplier component to the inner wall of the housing, thereby maximizing the creepage distance between the high-voltage side and the low-potential within a limited space, is beneficial for miniaturization design.

[0068] In this embodiment, the provided X-ray high voltage generator has a main insulating cylinder 93 and an insulating end cap 94 made of polymer insulating material, and a housing 91 and a housing cover 92 made of metal material.

[0069] The X-ray high-voltage generator provided in this embodiment uses a mechanical structure to fix the low-voltage side of the voltage multiplier component to the housing 91 with a single-end cantilever, so that the high-voltage side of the voltage multiplier component is suspended in the transformer oil 5. This avoids contact between the high-voltage side structural components and surrounding devices, increases the creepage distance between the high-voltage side and the ground potential, and meets the design requirements of the creepage distance of the high-voltage side of the product under the premise of effective fixation.

[0070] The X-ray high-voltage generator provided in this embodiment has the following overall installation steps:

[0071] A voltage multiplier module is formed by installing voltage multiplier equalizing rings 2 around the voltage multiplier plate 1. Then, each voltage multiplier module passes through the filament transformer assembly 6 through the filament mounting holes on both sides of the voltage multiplier plate 1 for fixation. Adjacent voltage multiplier modules are electrically connected using banana contact fingers or other electrical connection structures. An electrical adapter 8 is installed on the highest voltage side. A high voltage equalizing ring 95 and a high voltage socket guide 7 are installed on the electrical adapter 8 to form a voltage multiplier assembly. The voltage multiplier assembly is then installed inside the main insulating cylinder 93. The high voltage side is shielded and insulated using an end insulating cap 94. The transformer 5 is then installed on one side of the voltage multiplier assembly. The secondary output lead of the transformer 5 is connected to the first-stage voltage multiplier module of the voltage multiplier assembly. This forms the core of the high voltage generator. The entire core is then fixed on one side of the housing 91. At the same time, a high voltage socket 4 is inserted into the voltage multiplier assembly from this side. Finally, the housing cover 92 is installed on the housing 91. Finally, insulating oil from the transformer 5 is injected into the housing 91 as the insulating medium.

[0072] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
