Description

A high-voltage power supply structure for an X-ray source Technical Field

[0001] This utility model relates to a high-voltage power supply structure for an X-ray source, belonging to the field of X-ray source manufacturing technology. Background Technology

[0002] Micro-focus X-ray sources are high-performance X-ray generating devices that reduce the size of the X-ray focus to the micrometer level (typically ≤30μm) through precise design. Their core advantage lies in high-resolution imaging capabilities, and they are widely used in fields such as industrial inspection, semiconductor manufacturing, and medical diagnostics.

[0003] The X-ray source device mainly consists of an X-ray tube and a high-voltage power supply. The high-voltage power supply converts low-voltage DC electricity into 10kV~300kV high-voltage DC electricity, which is applied between the cathode and anode components of the X-ray tube.

[0004] High-voltage power supplies mainly consist of voltage multiplier circuits composed of capacitors and diodes. Traditional voltage multiplier modules solder the capacitors and diodes onto the same circuit board, with power input and output led out via wires. The overall module height increases with the number of voltage multiplier stages, resulting in a larger overall device size and affecting aesthetics. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an X-ray source high-voltage power supply structure that reduces the height of the high-voltage power supply and makes the overall structure compact and aesthetically pleasing.

[0006] The technical solution adopted by this utility model to solve the above problems is as follows: an X-ray source high-voltage power supply structure, including a PCB base plate, two symmetrically arranged connectors inserted into the PCB base plate, and capacitor PCBs respectively snapped into the connectors, the two capacitor PCBs being arranged opposite to each other; a capacitor unit is respectively arranged on the inner side of each capacitor PCB; a diode unit is provided between the two capacitor PCBs, and the two ends of the diode unit are electrically connected to the capacitor PCBs respectively; a PCB top plate is connected between the tops of the two capacitor PCBs; a spring pin is provided on the PCB top plate, the power is input through the PCB base plate, and then the power is output through the spring pin.

[0007] The connector is a card slot connector.

[0008] Each of the capacitor units includes multiple capacitors, which are evenly distributed along the height direction of the capacitor PCB board.

[0009] The diode unit includes multiple diodes, which are evenly distributed along the height direction of the capacitor PCB board.

[0010] Through holes are formed on the capacitor PCB, and the diameter of the through holes matches the diameter of the diode leads. The diode leads are inserted into the through holes.

[0011] Compared with existing technologies, the advantages of this utility model are as follows: An X-ray source high-voltage power supply structure is provided, with capacitors soldered in two groups onto corresponding capacitor PCBs, and diodes connected between the two capacitor PCBs. The arrangement of the diodes fully utilizes three-dimensional space, reducing the dimensions in the height direction, resulting in an overall height reduction of approximately 40% compared to traditional arrangements. The capacitor PCBs are mounted on the PCB base plate via slot connectors, facilitating installation, disassembly, and maintenance. This application features a compact structure with a small and aesthetically pleasing overall design. Attached Figure Description
