Description

Technical Field

[0001] This application relates to the field of X-ray tube technology, and in particular to an anode high-voltage connector. Background Technology

[0002] With the widespread use of medical CT (X-ray computed tomography) imaging technology, CT scans have become a primary means of detecting viral infections in the lungs. As the crucial link between the CT machine and the high-voltage X-ray tube, the stable and reliable anode high-voltage connector is a vital component ensuring the normal operation of the X-ray tube.

[0003] An X-ray tube contains two electrodes: an anode and a cathode, which serve as a target to receive electron bombardment and a filament to emit electrons, respectively. Both electrodes are sealed within a high-vacuum glass or ceramic housing. The power supply section of the X-ray tube includes at least a low-voltage power supply to heat the filament and a high-voltage power supply to apply high voltage to the electrodes. The anode high-voltage connector serves as the bridge connecting the X-ray tube anode target to the high-voltage power supply. For rotating anode X-ray tubes, the high-speed rotation of the target disk inevitably causes vibration of the entire anode assembly, negatively impacting the stability of other connecting components. When the anode high-voltage connector experiences abnormal loosening, poor contact, or insulation defects in its connection to the X-ray tube anode and high-voltage power supply, high-voltage breakdown and arcing are likely to occur during X-ray tube exposure, damaging the X-ray tube and high-voltage connecting components. Simultaneously, the vibration of mechanical components generates significant noise and may even cause resonance in specific frequency ranges, further affecting the product's mechanical stability. On the other hand, from the perspective of the overall mechanical structure design of CT X-ray tubes, a streamlined component space design is necessary; otherwise, it will inevitably increase the manufacturing materials and the volume and weight of the X-ray tube, thereby increasing the mechanical load on the CT gantry during high-speed rotation.

[0004] The existing defects of the anode high-voltage connector for X-ray tube assemblies are as follows: 1) The structure is complex, with low reliability of the interconnection of multiple parts, which wastes manpower and requires high installation and operation skills; 2) After repeated plugging and unplugging, the electrical contact surface of the electrical connector connected to the X-ray tube assembly is easily damaged, resulting in false contact and abnormal high-voltage arcing of the micro-gap X-ray tube; 3) The electrical components of the existing anode high-voltage connector are adjustable moving parts, which can easily lead to reduced connection stability of the connecting parts when the CT gantry rotates at high speed.

[0005] The existing technology has many technical problems, such as the complex structure of the anode high-voltage connector, the easy damage to the electrical contact surface after repeated plugging and unplugging of the electrical connector connected to the X-ray tube assembly, resulting in false contact, abnormal high-voltage arcing of the micro-gap X-ray tube, and low connection stability of the connecting components. There is currently no effective solution to these problems. Utility Model Content

[0006] This invention provides an anode high-voltage connector to at least solve the technical problems of existing anode high-voltage connectors, such as complex structure, easy damage to electrical contact surfaces after repeated plugging and unplugging of electrical connectors connected to X-ray tube assemblies, resulting in false contact, abnormal high-voltage arcing of micro-gap X-ray tubes, and low connection stability of connecting components.

[0007] According to one aspect of this application, an anode high-voltage connector is provided, comprising: a cable end plug connected to a high-voltage power supply, a high-voltage cable, a tubular mounting flange, leads, and terminals, wherein the high-voltage cable is fixedly connected to the cable end plug and the tubular mounting flange respectively; the tubular mounting flange is fixedly connected to the housing of an X-ray tube assembly; the leads are fixedly connected to the tubular mounting flange and the terminals respectively, and the leads and terminals are disposed inside the housing of the X-ray tube assembly; and the terminals are used for fixed connection to an anode connection assembly of the X-ray tube assembly.

[0012] Alternatively, the leads are connected to the terminals by crimping followed by soldering.

[0013] Alternatively, the mounting flange, leads, and terminals of the conduit can be connected by applying insulating sealant.

[0014] In this embodiment, compared to the complex structure of existing anode high-voltage connectors, the anode high-voltage connector in this technical solution has a simple structure. It simply integrates the cable end plug, high-voltage cable, tubing mounting flange, lead wire, and terminal block into a single unit, significantly reducing the number of components and simplifying the structure compared to existing technologies. Furthermore, all components of the anode high-voltage connector in this technical solution are fixedly connected, thereby improving the connection stability of the connecting parts when the CT gantry rotates at high speed. Additionally, the terminal block and tubing mounting flange of the anode high-voltage connector in this technical solution are fixedly connected to the X-ray tube assembly, eliminating the need for repeated insertion and removal, thus avoiding issues such as false contact and abnormal high-voltage arcing in the micro-gap X-ray tube. This solves the technical problems of existing anode high-voltage connectors having complex structures, and the electrical contact surfaces being easily damaged after repeated insertion and removal of the electrical connectors connected to the X-ray tube assembly, leading to false contact, abnormal high-voltage arcing in the micro-gap X-ray tube, and low connection stability of the connecting parts.

[0024] Figure 1 An exemplary schematic diagram of the anode high-voltage connector according to an embodiment of this application is shown. (Refer to...) Figure 1 As shown, an anode high-voltage connector 100 is provided, including: a cable end plug 110 connected to a high-voltage power supply, a high-voltage cable 120, a sleeve mounting flange 130, a lead wire 140, and a terminal block 150. The high-voltage cable 120 is fixedly connected to the cable end plug 110 and the sleeve mounting flange 130 respectively; the sleeve mounting flange 130 is fixedly connected to the housing 210 of the X-ray tube assembly 200; the lead wire 140 is fixedly connected to the sleeve mounting flange 130 and the terminal block 150 respectively, and the lead wire 140 and the terminal block 150 are disposed inside the housing 210 of the X-ray tube assembly 200; and the terminal block 150 is used to be fixedly connected to the anode connection assembly 220 of the X-ray tube assembly 200.

[0025] As described in the background section, the existing defects of the anode high-voltage connector for X-ray tube assemblies are as follows: 1) The structure is complex, with multiple parts interconnected, resulting in low reliability, wasting manpower, and requiring high installation and operation standards; 2) After repeated plugging and unplugging, the electrical contact surfaces of the electrical connectors connected to the X-ray tube assembly are easily damaged, leading to false contact and abnormal high-voltage arcing in the micro-gap X-ray tube; 3) The electrical components of the existing anode high-voltage connectors are adjustable moving parts, which can easily lead to reduced connection stability when the CT gantry rotates at high speed.

[0026] To address the aforementioned technical problems, the technical solutions provided in this application, with reference to... Figure 2As shown, the cable end plug 110, high-voltage cable 120, tubular mounting flange 130, lead wire 140, and terminal block 150 are sequentially fixedly connected. When it is necessary to connect the high-voltage power supply 300 to the X-ray tube assembly 200 via the anode high-voltage connector 100, the cable end plug 110 of the anode high-voltage connector 100 is connected to the high-voltage power supply 300, and the tubular mounting flange 130 is connected to the housing (210) of the X-ray tube assembly 200. The lead wire 140 and terminal block 150 connected to the tubular mounting flange 130 are disposed within the housing (210) of the X-ray tube assembly 200, and the terminal block 150 is connected to the anode connection assembly 220 of the X-ray tube assembly 200, thereby enabling the X-ray tube assembly 200 to be connected to the high-voltage power supply 300 via the anode high-voltage connector 100.

[0027] Compared to the complex structure of existing anode high-voltage connectors, the anode high-voltage connector 100 in this technical solution has a simple structure. It simply integrates the cable end plug 110, high-voltage cable 120, tubular mounting flange 130, lead wire 140, and terminal block 150 into a single unit, significantly reducing the number of components and simplifying the structure. Furthermore, all components of the anode high-voltage connector 100 in this technical solution are fixedly connected, thereby improving the connection stability of the connecting parts when the CT gantry rotates at high speed. Additionally, the terminal block 150 and tubular mounting flange 130 of the anode high-voltage connector 100 in this technical solution are fixedly connected to the X-ray tube assembly 200, eliminating the need for repeated insertion and removal, thus avoiding issues such as false contact and abnormal high-voltage arcing in the micro-gap X-ray tube. This solves the technical problems of existing anode high-voltage connectors, where the electrical contact surfaces are easily damaged after repeated insertion and removal of the electrical connectors connected to the X-ray tube assembly, leading to false contact, abnormal high-voltage arcing in the micro-gap X-ray tube, and low connection stability of the connecting parts.

[0028] Optionally, the cable end plug 110 is a CA1 three-core cable end plug. Thus, the CA1 three-core cable end plug ensures a stable and secure connection between the high-voltage power supply 300 and the anode high-voltage connector 100, while its three-core structure provides the necessary signal or control lines to meet the operational requirements of the X-ray tube assembly 200.

[0029] Optionally, lead 140 is a single-core multi-strand lead. The multi-strand structure of this single-core multi-strand lead makes it flexible and highly resistant to breakage, thereby improving the adaptability of the anode high-voltage connector 100 to different X-ray tube assemblies when bending or movement is required. Furthermore, the multi-strand wire can carry larger currents and reduce resistance, improving power transmission efficiency.

[0030] Optionally, terminal block 150 is an O-type terminal block. Specifically, refer to... Figure 3 As shown, when terminal 150 is an O-type terminal, it is fixed to the anode connection assembly 220 of the X-ray tube assembly 200 using screws 230 with connecting threads. Screw 230 can be a hexagonal head retaining flange screw. Thus, the O-type terminal in this technical solution can be fixedly connected to the X-ray tube assembly with screws, preventing the anode high-voltage connector 100 from falling off during high-speed rotation of the CT gantry. Furthermore, even in cases of frequent disconnection and connection between the O-type terminal and the X-ray tube assembly, the screw-fixed connection between the X-ray tube assembly and the O-type terminal will not easily damage the electrical contact surface between the X-ray tube assembly and the anode high-voltage connector 100, preventing situations such as poor contact or abnormal high-voltage arcing in the micro-gap X-ray tube.

[0031] Optionally, terminal 150 is a male quick-connect terminal. Specifically, terminal 150 of the anode high-voltage connector 100 can be a male quick-connect terminal with a threaded ring, and the anode connection component 220 of the X-ray tube assembly is a female with external threads. The male quick-connect terminal and the female connector are then connected via a mating connection, thereby achieving connection between the X-ray tube assembly and the anode high-voltage connector 100 through thread tightening. This improves the connection stability between the anode high-voltage connector 100 and the X-ray tube assembly 200. Furthermore, it avoids damage to the electrical contact surface between the X-ray tube assembly and the anode high-voltage connector 100 caused by frequent disconnection or connection of the male quick-connect terminal and the X-ray tube assembly, which could lead to poor contact and abnormal high-voltage arcing in the micro-gap X-ray tube.

[0032] Optionally, the lead wire 140 is connected to the terminal block 150 by crimping followed by soldering. Specifically, the lead wire 140 is first inserted into the terminal block 150 and crimped using a crimping tool. Pressure is applied to deform the metal material, thus achieving a tight connection between the lead wire 140 and the terminal block 150. After crimping, to further enhance the reliability and stability of the electrical connection, solder is added to the joint and heated to melt, allowing it to penetrate into the gap and form a strong solder joint, thereby securing the connection between the lead wire 140 and the terminal block 150.

[0033] Optionally, the mounting flange 130, lead wire 140, and terminal block 150 are connected by pouring insulating sealant. This improves the waterproof and moisture-proof performance of the connection, and also enhances its resistance to high and low temperatures and its anti-aging properties.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0035] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.
