[0022] The following describes in detail the application of the technical solution of the present invention in specific implementation in conjunction with the accompanying drawings to help those skilled in the art to implement the technical solution of the present invention. The present invention is applied to a high-voltage generator, which transmits high voltage electricity generated by the high-voltage generator to the outside.

[0023] like Figure 1 and Figure 2As shown, the appearance and internal structure of the high-voltage generator 100 are as follows: The structure of the high-voltage generator 100 includes a rectangular box-shaped housing 110, which is firmly fastened by a plurality of fixing screws 111. A plurality of heat dissipation holes 120 are provided on one side of the housing 110. These heat dissipation holes 120 are neatly arranged to ensure effective heat dissipation of the internal components when working at high voltage. A high-voltage output interface 130 is installed on the other side. The interface 130 is fixed to the housing 110 by screws 131 to ensure the stability and reliability of the connection of the interface 130. A smaller auxiliary connection interface 140 is provided next to the high-voltage output interface 130 for other necessary electrical connections. A series of ventilation grilles 150 are provided on the top surface to further enhance the heat dissipation performance through natural convection or forced air cooling to ensure that the high-voltage generator 100 maintains a suitable operating temperature during operation.

[0024] The back of the high-voltage generator 100 features multiple interfaces to meet various connection requirements. A multi-pin connector 160 is used for control signal connections. A series of electrical interfaces 170 ensure reliable electrical connections and signal transmission between the high-voltage generator 100 and external devices.

[0025] The internal structure of the high-voltage generator 100 includes the following components: a high-voltage output interface connector 180 located on the side of the housing 110 is fixed by screws 131. The internal structure includes a high-voltage transformer 190. A plurality of rectifier circuit components 200 are arranged on one side of the high-voltage transformer 190. Next to the rectifier circuit components 200, a series of high-voltage capacitors 210 are arranged. These high-voltage capacitors 210 are connected by wires. The high-voltage power supply can be connected in parallel or as shown in FIG. Figure 2 100 ). A control circuit board 220 is mounted on the other side of the high-voltage transformer 190. This circuit board is connected to an external control system via a multi-pin connector 160 and is responsible for overall control and regulation of the high-voltage generator 100. Multiple mechanical fasteners 240, including screws 111, brackets, and stoppers, are also located inside to ensure that all components are securely fastened to prevent loosening or displacement due to vibration or other factors during operation.

[0026] A PCB 250 is disposed within the housing of the high-voltage generator 100. A high-voltage transformer 190 is mounted on the PCB 250. Multiple rectifier circuit assemblies 200 are arranged on one side of the high-voltage transformer 190. A series of high-voltage capacitors 210 are disposed on one side of the rectifier circuit assemblies 200. Multiple resistors 280 are disposed on one side of the high-voltage capacitors 210. Those skilled in the art will appreciate that other necessary high-voltage components may also be disposed on the PCB 250.

[0027] The high-voltage output interface connector 180 is arranged above the PCB board 250, and its first end 291 is connected to the housing 110 of the high-voltage generator 100 through the flange 300. The connecting plate 301 of the flange 300 is arranged outside the high-voltage generator housing 110. The other side of the connection interface of the high-voltage connector 130 can be connected to the output interface (not shown in the figure) of the high-voltage PCB board 250 to output high voltage electricity through the connector 180. Please refer to Figure 3 and Figure 4 The high voltage output interface connector 180 is shown.

[0028] It should be noted that Figure 2 The capacitor 210, circuit board 250, resistor 280, and high-voltage transformer 190 are merely schematic diagrams of a modular structure. Circuit board 250 may be a multilayer board, and the components thereon may be connected between different layers. Those skilled in the art may adapt and modify the circuit board according to actual needs.

[0029] The high-voltage output interface connector 180 is a cylindrical structure as a whole, and its main body 290 is formed by machining from a rod. The design of the cylindrical structure enables the connector 180 to provide a stable and reliable connection in a high-voltage working environment. The rod can be formed through a precise machining process, which is convenient for non-standard customization of high-voltage connectors. The machining process enables the main body 290 to have a uniform wall thickness and smooth inner and outer surfaces. The machining process includes processes such as turning, milling and drilling. During processing, a hole with a larger diameter at the first end of the main structure (hereinafter referred to as the first hole 381) is first formed, and then a hole at the second end 292 (hereinafter referred to as the second hole 382) is formed. A third hole 383 with a diameter larger than the first hole 381 is formed at the first end 291. The third hole 383 is used to connect to the insulating tube of the flange 300.

[0030] Furthermore, the second end 292 of the main body 290 is disposed opposite to the first end 291 , and the cavity of the second end 292 forms a radially shrinking step structure 380 .

[0031] The aforementioned machining process offers flexibility in addressing the manufacturing needs of non-standard structures. Since the design of high-voltage output interface connector 180 may involve specific application scenarios and performance requirements, standardized structures cannot fully meet these needs. Machining allows for flexible adjustment of machining paths and process parameters based on specific design requirements, enabling the creation of non-standard structures that meet specific needs, ensuring the applicability and reliability of connector 180 in a variety of complex application environments.

[0032] Furthermore, the length of the main body 290 ranges from 190 mm to 210 mm, the diameter ranges from 18 mm to 22 mm, the inner diameter of the first hole 381 ranges from 8 mm to 12 mm, the inner diameter of the second hole 382 ranges from 2 mm to 6 mm, and the inner diameter of the third hole 383 ranges from 13 mm to 17 mm. With these precise dimensions, the high-voltage output interface connector 180 can maintain its excellent performance and reliability in a variety of complex and demanding high-voltage application environments, ensuring stable transmission of high-voltage current.

[0033] Furthermore, the main body 290 is made of a conductive material selected from copper, aluminum, or silver-plated copper. The third hole 383, which has a larger diameter, is used to connect to the flange 300. To further improve the connection between the high-voltage connector 180 and the flange 300, the inner wall of the hole at the first end 291 of the main body 290 is provided with connecting threads 340. The insulating tube 350 is provided with threads that engage with the connecting threads 340, and the insulating tube 350 and the inner wall of the hole are connected by insulating glue.

[0034] Furthermore, the insulating adhesive includes epoxy resin adhesive, polyurethane adhesive, silicone rubber adhesive, and acrylic adhesive. The flange 300 is provided at the first end 291 of the high-voltage output interface body 290 and is used to connect the high-voltage connector 130 and the high-voltage cable 370 joint. The flange 300 is an injection-molded structure or a ceramic structure. The flange 310 also includes a fixing plate 301 connected to the insulating tube 350. The fixing plate 301 is used to fix the flange 300 and the body 290 on the chassis plate 390 of the high-voltage connector 180. The fixing plate 301 includes a fixing hole 391 for connecting to the chassis 390. The fixing hole 391 is used to pass the fixing screw 131. The design of the fixing plate 301 allows the flange 310 to be easily connected to the fixing plate 301 through the insulating tube 350, which facilitates installation and provides additional mechanical support.

[0035] Furthermore, the insulating sleeve 350 and the flange 300 are made of an insulating material, and the insulating material is selected from one of polytetrafluoroethylene, epoxy resin, silicone rubber or ceramic material.

[0036] Furthermore, if Figure 4 As shown, the flange 300 further includes a second tube portion 352 on the circumferential outer side of the insulating sleeve 350. When the flange 300 is connected to the first end 291, the second tube portion 352 is sleeved around the outer circumference of the first end 291. The second tube portion 352 can be fixed to the first end 291 of the main body 290 using insulating glue. The second tube portion 352 is used for insulation between the chassis 390 and the high-voltage connector 180.

[0037] An insulating sleeve 320 is disposed on the exterior of the high-voltage output interface body 290; it is used to connect to an external high-voltage cable 370. During connection, the conductive inner core of the external high-voltage cable 370 is inserted into a first hole 381 within the high-voltage interface connector 180, electrically connecting the external high-voltage cable 370 to the first end 291 of the connector 180. A standard circular post 330 is disposed within a second hole 382 at the second end 292 of the connector 180. The standard circular post 330 is press-fitted into the second end 292 of the high-voltage output interface body 290 through an interference fit. The standard circular post 330 is connected to the output port of the high-voltage PCB 250 via the high-voltage cable 331. This connection between the two ends achieves electrical connection to the high-voltage connector 180.

[0038] Furthermore, after the standard circular pillar 330 is pressed into the step structure 380 of the second end 292, it is fixed by applying glue (not shown). The glue is a conductive glue, including: silver-filled conductive glue, carbon-filled conductive glue, nickel-filled conductive glue, gold-filled conductive glue, and aluminum-filled conductive glue.

[0039] Reference Figure 5 As shown, the high-voltage cable 370 includes a connecting flange portion 371 and a cable conductor portion 372. The connecting flange portion 371 is located at one end of the cable 370 and includes a cylindrical tube portion 373 and a fixing plate 374. The fixing plate 301 has fixing holes for fixing with screws 131. The flange 300 is used to firmly connect the high-voltage cable 370 to the chassis plate 112 of the high-voltage equipment to ensure the mechanical stability and electrical reliability of the connection. The cable conductor portion 372 is composed of multiple strands of twisted metal wires, which are usually made of highly conductive materials such as copper or aluminum. The multi-strand twisted design increases the flexibility and conductivity of the cable 372, ensuring that high-voltage current can be efficiently transmitted while reducing resistance and inductance.

[0040] In summary, the present application has made two advances compared to the prior art: through precision machining processes (including turning, milling and drilling), a cylindrical main body structure with uniform wall thickness and smooth inner and outer surfaces is manufactured. Machining flexibly responds to the manufacturing needs of non-standard structures, ensuring that the connector can adapt to specific application scenarios and performance requirements. This process enables the connector to provide a stable and reliable connection under high-voltage working environments, solving the problem that standardized structures cannot fully meet diversified needs. The flange is arranged at the first end of the main body. The flange is an injection molded structure or a ceramic structure, and includes a fixing plate and a fixing hole. It is fixed to the chassis plate by screws to provide additional mechanical support and convenient installation. The flange design enhances the mechanical stability and electrical reliability of the connection, and solves the problem of insufficient connection performance between the high-voltage connector and the flange.
