[0002] An X-ray source is a device that generates X-rays. It mainly includes an X-ray tube, a high-voltage power supply, and a control circuit. The high-voltage power supply converts low-voltage DC power into stable high-voltage DC power through a series of power electronic conversions, which is then supplied to the X-ray tube.

[0003] When X-ray sources are used in mobile devices (such as moving transportation equipment), grounding failures are prone to occur, which can further cause safety issues in the use of X-ray sources. Utility Model Content

[0004] The purpose of this invention is to address the issue of grounding failure of the high-voltage circuit encapsulation module in existing X-ray source devices when used in mobile scenarios, and to provide an installation component that enables reliable grounding of the high-voltage circuit encapsulation module.

[0005] To achieve the above objectives, this utility model provides an installation assembly for installing a high-voltage circuit encapsulation module within the cavity of an X-ray source device. The high-voltage circuit encapsulation module has a first end and a second end opposite to each other in a first direction. The first end contacts a first inner surface of the cavity. The installation assembly includes an elastic conductive element capable of stretching and contracting along the first direction. The second end contacts a second inner surface of the cavity through the elastic conductive element. The second inner surface is disposed opposite to the first inner surface. When the high-voltage circuit encapsulation module is installed within the cavity, the elastic conductive element is in a state of compressive deformation.

[0006] Preferably, the mounting assembly further includes a metal base for mounting the elastic conductive element. The metal base has a mounting hole extending along the first direction. One end of the elastic conductive element abuts against the bottom of the mounting hole, and the other end extends out of the opening of the mounting hole.

[0007] Preferably, multiple elastic conductive elements and multiple mounting holes are provided, and the multiple mounting holes correspond one-to-one with the multiple elastic conductive elements.

[0008] Preferably, the mounting hole is a blind hole; the metal seat is disposed between the elastic conductive element and the high-voltage circuit packaging module; or the metal seat is disposed between the elastic conductive element and the second inner side of the chamber.

[0009] Preferably, the elastic conductive element is constructed as a spring.

[0010] Preferably, the mounting assembly further includes an insulating base arranged side by side with the metal base, the insulating base having a mounting cavity for the outlet terminals of the high-voltage circuit packaging module to extend into, and a notch on the side of the insulating base near the high-voltage circuit packaging module for the wiring of the outlet terminals to be led out.

[0011] This utility model also provides an X-ray source device, including a high-voltage circuit encapsulation module, which is installed in the cavity of the X-ray source device via the aforementioned mounting components.

[0012] Preferably, the X-ray source device includes a housing for enclosing and forming an accommodating space, and a partition is provided inside the housing to divide the accommodating space into multiple chambers, the multiple chambers including an oil tank chamber, an adapter plate being provided on the first inner side of the oil tank chamber, and the access terminal of the high-voltage circuit packaging module being configured to be able to be plugged into and cooperate with an electrical connector on the adapter plate along the first direction.

[0013] Preferably, an X-ray tube is installed inside the oil tank cavity, the output terminal of the high-voltage circuit encapsulation module is electrically connected to the X-ray tube, and the oil tank cavity is filled with insulating oil.

[0014] Preferably, the plurality of chambers further includes a control chamber located below or to the side of the fuel tank chamber, and a circuit board is installed in the control chamber.

[0015] Through the above technical solution, by contacting the first end of the high-voltage circuit packaging module with the first inner side of the cavity in the first direction, and then contacting the second end opposite to the first end with the second inner side of the cavity through an elastic conductive element, since the elastic conductive element itself can extend and retract along the first direction, the high-voltage circuit packaging module can be reliably pressed and installed between the opposite first inner side and second inner side of the cavity; by directly contacting the second end of the high-voltage circuit packaging module with the second inner side of the cavity through the elastic conductive element, the reliable grounding of the high-voltage circuit packaging module can be ensured by setting the second inner side of the cavity to a metal material.

[0016] The installation components provided by this utility model can effectively prevent the high-voltage circuit encapsulation module from shaking inside its cavity and causing grounding failure when the X-ray source device is in a moving state, or cause the connection terminal to be disconnected from the adapter plate, thus ensuring the working stability and safety of the X-ray source device.

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0025] In some existing application scenarios, such as mobile transportation equipment, X-ray source devices usually need to be in a mobile state. At this time, the high-voltage circuit packaging module may shake in the tank cavity, which can easily cause the high-voltage circuit packaging module to fail to ground or cause the connection between the access terminal and the adapter board to be broken, affecting the normal operation of the entire X-ray source device.

[0026] Based on this, the inventors of this application propose a mounting assembly for mounting a high-voltage circuit encapsulation module 1 within the cavity of an X-ray source device, in conjunction with... Figure 1 , Figure 2 and Figure 3 As shown, the high-voltage circuit packaging module 1 has a first end 101 and a second end 102 opposite to each other in a first direction. The first end 101 contacts the first inner side of the chamber. The mounting assembly includes an elastic conductive element 100 that can extend and retract along the first direction. The second end 102 contacts the second inner side of the chamber through the elastic conductive element 100. The second inner side is disposed opposite to the first inner side. When the high-voltage circuit packaging module 1 is installed in the chamber, the elastic conductive element 100 is in a state of pressure deformation.

[0027] In this utility model, the high-voltage circuit packaging module 1 includes a body and a metal material covering the surface of the body. The metal material can be aluminum foil or copper foil.

[0028] In the technical solution provided by this utility model, by contacting the first end 101 of the high-voltage circuit packaging module 1 in the first direction with the first inner side of the cavity, and then contacting the second end 102 opposite to the first end 101 with the second inner side of the cavity through the elastic conductive member 100, since the elastic conductive member 100 itself can extend and retract along the first direction, the high-voltage circuit packaging module 1 can be reliably pressed and installed between the opposite first inner side and second inner side of the cavity; by directly contacting the second end 102 of the high-voltage circuit packaging module 1 with the second inner side of the cavity through the elastic conductive member 100, the second inner side of the cavity can be made of metal material to ensure reliable grounding of the high-voltage circuit packaging module 1.

[0029] The installation components provided by this utility model can effectively prevent the high-voltage circuit encapsulation module 1 from shaking inside its cavity and causing grounding failure or disconnection between the access terminal and the adapter plate when the X-ray source device is in a moving state, thus ensuring the working stability and safety of the X-ray source device.

[0030] In some embodiments, the mounting assembly further includes a metal base 200 for mounting the elastic conductive element 100. The metal base 200 has a mounting hole 210 extending along the first direction. One end of the elastic conductive element 100 abuts against the bottom of the mounting hole 210, and the other end extends out of the opening of the mounting hole 210. In the above embodiments, by housing the elastic conductive element 100 in the mounting hole 210, a secure fit is ensured while the elastic conductive element 100 provides elastic force to firmly mount the high-voltage circuit packaging module 1 between opposing first and second inner surfaces within the cavity, and reliable grounding of the high-voltage circuit packaging module 1 is ensured.

[0031] In some embodiments, multiple elastic conductive elements 100 and mounting holes 210 are provided, with each mounting hole 210 corresponding to one of the multiple elastic conductive elements 100. It is understood that by providing multiple elastic conductive elements 100, reliable installation and effective grounding of the high-voltage circuit packaging module 1 can be ensured.

[0032] In some embodiments, the mounting hole 210 is constructed as a blind hole; it is understood that by providing the metal base 200, multiple elastic conductive elements 100 can be conveniently arranged. The metal base 200 can be set in any suitable position, as long as the elastic conductive elements 100 thereon can be used to reliably abut against and install the high-voltage circuit packaging module 1 between the opposite first inner side and second inner side of the cavity. In some embodiments of this utility model, such as Figure 1 As shown, the metal base 200 is disposed between the elastic conductive member 100 and the high-voltage circuit packaging module 1; in this case, one side of the metal base 200 is in contact with the high-voltage circuit packaging module 1, and the other side abuts against the second inner side of the chamber through the elastic conductive member 100.

[0033] In some other embodiments of this utility model, the metal seat 200 is disposed between the elastic conductive member 100 and the second inner side surface of the chamber (not shown in the figure). In this case, one side of the metal seat 200 is in direct contact with the second inner side surface of the chamber, and the other side abuts against the second end 102 of the high-voltage circuit packaging module 1 through the elastic conductive member 100.

[0034] In this invention, the elastic conductive element 100 can be any component capable of stretching and contracting along a first direction and possessing conductive properties. In some embodiments of this invention, the elastic conductive element 100 is constructed as a spring.

[0035] In some embodiments, the mounting assembly further includes an insulating base 300 arranged side-by-side with the metal base 200. The insulating base 300 has a mounting cavity for the terminals of the high-voltage circuit encapsulation module 1 to extend into, and a notch 310 is provided on the side of the insulating base 300 near the high-voltage circuit encapsulation module 1 for the wiring of the terminals to be led out. It is understood that this invention achieves grounding of the high-voltage circuit encapsulation module 1 by electrically connecting the outer surface of the high-voltage circuit encapsulation module 1 to the housing of the X-ray source device through the cooperation of the metal base 200 and the elastic conductive element 100. By arranging the insulating base 300 side-by-side with the metal base 200, the safety of the X-ray source device is improved.

[0036] It should be noted that in this invention, there is a significant potential difference between the input and output terminals of the high-voltage circuit packaging module 1. Therefore, designing them separately can improve safety. Specifically, an installation cavity is provided in the insulating base 300 for the terminals of the high-voltage circuit packaging module 1 to extend into, and a notch 310 is provided on the insulating base 300 for the wiring of the terminals to be led out. The wiring led out from the notch 310 can be directly electrically connected to the anode of the X-ray tube 2 located above the insulating base 300. In this invention, the structural design of the insulating base 300 also improves the insulation effect at the high-voltage connection point, effectively preventing the terminals from contacting the housing.

[0037] In some embodiments, an adapter plate 400 is provided on the first inner surface of the chamber, and the access terminal of the high-voltage circuit encapsulation module 1 is configured to be able to be plugged into and engaged with the electrical connector on the adapter plate 400 along the first direction. With the above configuration, after the high-voltage circuit encapsulation module 1 is installed in place, the elastic conductive element 100 is in a compressed state, that is, the elastic force of the elastic conductive element 100 can be used to achieve a reliable electrical connection between the access terminal and the electrical connector on the adapter plate 400.

[0038] In the above embodiments, the substrate of the adapter plate 400 is made of insulating material, and an electrical connector is embedded on the adapter plate 400; or, the substrate of the adapter plate 400 and the electrical connector can be integrally formed to ensure sealing.

[0039] This utility model also provides an X-ray source device, which includes a high-voltage circuit encapsulation module 1, which is installed in the cavity of the X-ray source device through the aforementioned mounting components.

[0040] In this invention, the X-ray source device with the above-mentioned mounting components ensures that even when the X-ray source device is in motion, it will not experience grounding failure due to the high-voltage circuit encapsulation module 1 shaking within the cavity, or cause the connection between the access terminal and the adapter plate to be disconnected, thus ensuring the working stability and safety of the X-ray source device.

[0041] Combination Figure 4 and Figure 5 As shown, in this utility model, the X-ray source device includes a housing 500 for enclosing and forming an accommodating space 510. A partition 600 is provided inside the housing 500 to divide the accommodating space 510 into multiple chambers. The multiple chambers include an oil tank chamber 5102. An adapter plate 400 is provided on the first inner side of the oil tank chamber 5102. The access terminal of the high-voltage circuit packaging module 1 is configured to be able to be plugged into and cooperate with the electrical connector on the adapter plate 400 along the first direction.

[0042] In this invention, an X-ray tube 2 is installed inside the oil tank cavity 5102, and the output terminal of the high voltage circuit encapsulation module 1 is electrically connected to the X-ray tube 2. The oil tank cavity 5102 is filled with insulating oil.

[0043] In this invention, the plurality of chambers also include a control chamber 5103, which is located below or to the side of the fuel tank chamber 5102, and a circuit board is installed inside the control chamber 5103.

[0044] The structure of the X-ray source device provided by this utility model will be further described below with reference to the accompanying drawings.

[0045] In one embodiment of the present invention, the X-ray source device includes a housing 500 for enclosing and forming an accommodating space 510. A partition 600 is provided inside the housing 500 to divide the accommodating space 510 into multiple chambers, and the multiple chambers are used to correspondingly accommodate multiple components of the X-ray source device.

[0046] The chamber includes a transformer mounting chamber 5101 and an oil tank chamber 5102 arranged sequentially along the front-rear direction of the housing 500, a control chamber 5103 located at the bottom of the transformer mounting chamber 5101 and the oil tank chamber 5102, and a wiring chamber 5104 located beside the transformer mounting chamber 5101. The wiring chamber 5104 is connected to the lower control chamber 5103 and the adjacent transformer mounting chamber 5101 through wire holes. Furthermore, a transition plate 400 capable of sealing the oil tank chamber 5102 is provided on the side near the oil tank chamber 5102. The substrate of the transition plate 400 is made of insulating material, and an electrical connector is embedded on the transition plate 400.

[0047] The oil tank cavity 5102 houses the X-ray tube 2 and the high-voltage circuit encapsulation module 1. The oil tank cavity 5102 is a sealed cavity filled with insulating oil. The cavity door of the oil tank cavity 5102 is located at the rear end of the housing 500, and the output end of the X-ray tube 2 is located at the top of the housing 500. The high-voltage circuit encapsulation module 1 has an input terminal and an output terminal. The input terminal is electrically connected to an electrical connector on the adapter plate 400, and the output terminal is electrically connected to the anode end of the X-ray tube 2.

[0048] In this invention, the insulating oil filled in the oil tank cavity 5102 serves two purposes: firstly, it provides insulation, and secondly, it transfers the heat generated by the X-ray tube 2 and the high-voltage circuit packaging module 1 during operation to the housing 500 and dissipates it.

[0049] During the operation of the X-ray source device, the insulating oil filled in the oil tank cavity 5102 will absorb heat and expand. Therefore, a breather valve mounting hole 520 is provided at the front end of the housing 500. The breather valve mounting hole is connected to the oil tank cavity 5102, and the breather valve is sealed and installed on the housing 500.

[0050] A high-frequency transformer and an inductor are installed inside the transformer mounting cavity 5101. The primary coil of the high-frequency transformer is electrically connected to the inductor, and the inductor is electrically connected to the power interface on the housing 500. The secondary coil of the high-frequency transformer is electrically connected to the high-voltage circuit encapsulation module 1 through the electrical connector on the adapter plate 400. The secondary coil of the high-frequency transformer is also electrically connected to the cathode of the X-ray tube 2.

[0051] The X-ray source device provided by this invention can maintain stable performance even in complex application environments, ensuring the service life and safety of the equipment.

Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
