Description

[Technical Field]

[0001] The present invention relates to a connection device between a high voltage power supply and an X-ray tube, and to an X-ray source including the connection device, which belongs to the technical field of radiation image processing. [Background technology]

[0002] An X-ray tube (abbreviated as X-ray tube) is a vacuum diode operated at high voltage. It has two electrodes: a filament that acts as the cathode, emitting electrons, and a target that acts as the anode, receiving the electrons. The two electrodes are sealed in a high-vacuum glass or ceramic housing. X-ray tubes are used in medicine for diagnosis and treatment, and in engineering for non-destructive testing of materials, structural analysis, spectroscopy, and negative irradiation.

[0003] Currently, there are two types of connection methods for high-voltage power supplies and X-ray tubes: integrated connection and independent connection. Here, the integrated connection method is a complete structure in which the X-ray tube is mounted inside the high-voltage power supply, and is primarily suitable for low-power, small-scale applications. Furthermore, if either one breaks down, repair or disassembly is difficult, and the high-voltage power supply and X-ray tube must be replaced as a whole. The independent connection method uses a specialized high-voltage socket and high-voltage plug to connect the high-voltage power supply and X-ray tube, and is primarily suitable for high-power, large-capacity applications. Furthermore, the total volume and weight of the high-voltage power supply and X-ray tube using the independent connection method are relatively large.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0031] The technical contents of the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0032] As shown in Figures 1 and 2, the connection device between a high-voltage power supply and an X-ray tube provided by the present invention comprises a first connection unit 100 and a second connection unit 200. The first connection unit 100 serves as the output end of the high-voltage power supply and is attached to the high-voltage power supply and connected to the high-voltage output end of the high-voltage power supply. The second connection unit 200 serves as the power input end of the X-ray tube and is attached to the X-ray tube and connected to the cathode of the X-ray tube. After applying a sufficient amount of silica gel between the first connection unit 100 and the second connection unit 200, they are detachably inserted and the air between them is pushed out, thereby detachably connecting the high-voltage power supply and the X-ray tube.

[0033] Specifically, the first connection unit 100 may be embedded in the high-voltage power supply housing 1, or may be coupled to the first fixing member 8 of the high-voltage power supply so that the first connection unit 100 is located outside the fixing member of the high-voltage power supply. The second connection unit 200, which is inserted into the first connection unit 100, is structured to fit into the first connection unit 100. The structures of the first connection unit 100 and the second connection unit 200 will be described in detail below with reference to specific examples.

[0034] Example 1 As shown in Figures 1 to 3, the first connection unit 100 provided by this embodiment is embedded in the high-voltage power supply housing 1. The first connection unit 100 includes a first housing 7 embedded in the high-voltage power supply housing 1, with high-voltage power supply output terminals (corresponding to sockets) 4 provided at one end of the first housing 7, and the port cross section at the other end of the first housing 7 being positioned at the same height as the cross section of a first fixing member 8 at the port of the high-voltage power supply housing 1, and being fixed to the first fixing member 8. Here, the first housing 7 is made of a non-metallic material.

[0035] 2 and 3, in this embodiment, in order to ensure uniformity of the local electric field, a first shield ring 5 may be provided around the outer periphery of the high-voltage power supply output terminal 4. The first shield ring 5 is a metallic shield ring with guide posts made of a metal material.

[0036] As shown in Figure 3, the high-voltage power supply output terminal 4 serves as the output end of the high-voltage power supply for outputting a preset high voltage, and can be connected directly or via a cable 3 to the high-voltage module 2 of the high-voltage power supply. Whether the connection between the high-voltage power supply output terminal 4 and the high-voltage module 2 is via a cable connection or a direct connection can be determined according to actual needs.

[0037] The length of the first housing 7 must satisfy the creepage distance requirement. That is, the distance between the end of the high-voltage power supply output terminal set along the first housing 7 and the first fixing member 8 attached to the port of the high-voltage power supply housing 1 must also satisfy the creepage distance requirement. The length of the first housing 7 is adjusted according to the high voltage that the high-voltage module 2 actually needs to output. The length of the first housing 7 is determined based on a high voltage of 1 kV per 1 mm of the first housing 7 length. For example, if the high-voltage module 2 actually needs to output a high voltage of 5 kV, the length of the first housing 7 can be 5 mm.

[0038] Here, the first fixing member 8 is provided with a through-hole that communicates with the port of the first housing 7, and this through-hole has the same shape and size as the port of the first housing 7. Therefore, the first housing 7 can be embedded in the high-voltage power supply housing via the through-hole. After embedding the first connection unit 100 in the high-voltage power supply housing 1, a high-voltage insulation process is performed, such as filling the space between the first housing 7 and the high-voltage power supply housing 1 with an insulating filler such as high-voltage oil or high-voltage insulating rubber (insulating filler 6 as shown in FIG. 3).

[0039] In actual processing, the first housing 7 can be integrally processed with the first fixing member 8 and the high-voltage power supply housing 1 using an integrated molding technique according to the actual needs of the user. When one end of the first housing 7, on which the high-voltage power supply output terminal 4 and the first shield ring 5 are provided, is fitted into the high-voltage power supply housing 1 in alignment with the through-hole of the first fixing member 8, the port at the other end of the first housing 7 can be fixed to the first fixing member 8 in a seamless connection manner. This connection method is a conventional, well-established process technology, so will not be described in detail here.

[0040] As shown in FIGS. 1, 2, and 4, the second connection unit 200 is connected to a second fixing member 15 of the X-ray tube housing. Specifically, the second connection unit 200 includes a second housing 12, one end of which is provided with a power input terminal 9 (corresponding to a plug) and a second shield ring 10, and the other end of the second housing 12 is fixed to the second fixing member 15 of the X-ray tube housing. The second housing 12 is made of a non-metallic material. The shape and size of the second housing 12 are the same as those of the first housing 7, and the power input terminal 9 and the second shield ring 10 also correspond to the high-voltage power output terminal 4 and the first shield ring 5. As shown in FIG. 5, the second housing 12 and the power input terminal 9 provided thereon can be detachably inserted into the first housing 7 and the high-voltage output terminal 4 provided thereon.

[0041] 1 and 4, in this embodiment, in order to ensure uniformity of the local electric field, a second shield ring 10 may be further provided around the outer periphery of the power input terminal 9. The second shield ring 10 is a metallic shield ring with guide posts made of a metal material.

[0042] As shown in Figure 4, the power input terminal 9 can be connected directly or via a cable 11 to the cathode of the X-ray tube core 14 as the power input terminal for receiving the required high voltage of the X-ray tube. Whether the connection between the power input terminal 9 and the X-ray tube core 14 is via a cable connection or a direct connection can be determined according to actual needs.

[0043] As shown in FIGS. 1 and 4 , the second fixing member 15 has a through-hole for fixing the anode of the X-ray tube core 14. This through-hole has the same shape and size as the anode of the X-ray tube core 14. Therefore, the anode of the X-ray tube core 14 can be passed through the through-hole and then fixed to the second fixing member 15 by a seamless connection method. After the X-ray tube core 14 is attached, the power input terminal 9 of the second housing 12 is connected to the cathode of the X-ray tube core 14. Then, the second housing 12 is sleeve-connected to the outside of the X-ray tube core 14 and fixed to the second fixing member 15 by a seamless connection method. After that, high-voltage insulation treatment is performed, such as filling the space between the second housing 12 and the X-ray tube core 14 with an insulating filler such as high-pressure oil or high-pressure insulating rubber (insulating filler 13 as shown in FIG. 4 ). Furthermore, when actually processing, the second housing 12, X-ray tube core 14, and second fixing member 15 can also be integrally processed using an integral molding technique according to the actual needs of the user.

[0044] In this embodiment, when high voltage needs to be supplied to the X-ray tube using a high-voltage power supply, the second connection unit 200 attached to the X-ray tube and the first connection unit 100 attached to the high-voltage power supply are each coated with a sufficient amount of silica gel and then inserted. The first fixing member 8 and the second fixing member 15 are then fastened with bolts, and air is expelled from between them to prevent discharge from the high-voltage power supply and secure the high-voltage power supply and the X-ray tube. In the event of a malfunction in the high-voltage power supply or the X-ray tube, the high-voltage power supply and the X-ray tube can be separated simply by removing the bolts on the first fixing member 8 and the second fixing member 15 and removing the X-ray tube from the high-voltage power supply, facilitating malfunction inspection and maintenance of both the high-voltage power supply and the X-ray tube. Connecting the high-voltage power supply and the X-ray tube in this manner not only reduces the installation volume for the high-voltage power supply and the X-ray tube, but also facilitates disassembly for inspection and repair in the event of a malfunction in either the high-voltage power supply or the X-ray tube.

[0045] <Example 2> The structures of the first connection unit 100 and the second connection unit 200 provided in this embodiment differ from those of the first embodiment in the following respects: the high-voltage power supply and the X-ray tube are connected by inserting the first connection unit 100, to which a high-voltage power supply is attached, into the second connection unit 200, to which an X-ray tube is attached, and the high-voltage power supply and the X-ray tube are separated by pulling out the first connection unit 100 from the second connection unit 200. That is, the first connection unit 100 and the second connection unit 200 provided in the second embodiment are connected in a manner opposite to that of the first embodiment.

[0046] 1 to 5, the structure of the first connection unit 100 in Example 2 is similar to that of the second connection unit 200 in Example 1, and it is easy to imagine that the first connection unit 100 is connected to the first fixing member of the high-voltage power supply housing. Similar to the first connection unit 100 in Example 1, the second connection unit 200 is embedded in the X-ray tube housing. Specifically, in the first connection unit 100, high-voltage power supply output terminals (equivalent to plugs) are provided at one end of the first housing, and the other end of the first housing is coupled to the outside of the first fixing member of the high-voltage power supply housing.

[0047] In this embodiment, in order to ensure uniformity of the local electric field, a first shield ring can be provided around the outer periphery of the high voltage power supply output terminal.

[0048] Here, the first fixing member has a through-hole communicating with the port of the first housing, and this through-hole connects the high-voltage power supply output terminal to the high-voltage module of the high-voltage power supply directly or via a cable. After the high-voltage power supply housing and the first housing are fixed to the first fixing member using a seamless connection method, high-voltage insulation is performed by filling the space between the high-voltage power supply housing and the first housing with high-voltage oil or high-voltage insulating rubber. Furthermore, when actually processing the product, the first housing, high-voltage power supply housing, and first fixing member can be processed as a single unit using an integrated molding technique depending on the actual needs of the user.

[0049] In the second unit provided by this embodiment, a power supply input terminal (corresponding to a socket) is provided at one end of the second housing, and the cross section of the port at the other end of the second housing is positioned at the same height as the cross section of the second fixing member in the X-ray tube housing and is fixed to the second fixing member. Here, the second fixing member is provided with a through hole communicating with the port of the second housing, and this through hole has the same shape and size as the port of the second housing, so the second housing can be embedded in the X-ray tube housing, and high-voltage insulation treatment can be performed by filling the space between the second housing and the X-ray tube housing with high-pressure oil or high-pressure insulating rubber. Furthermore, the power supply input terminal is connected to the cathode of the X-ray tube core in the same manner as in Example 1, and a repeated description will not be given here.

[0050] In this embodiment, a second shield ring may be provided around the power input terminal to ensure uniformity of the local electric field.

[0051] Similarly, in actual processing, the second housing, second fixing member, and X-ray tube housing can be integrally processed using an integrated molding technique according to the actual needs of the user. One end of the second housing, which is provided with the power input terminal and the second shield ring, can be fitted into the X-ray tube housing through the through-hole of the second fixing member, and the port at the other end of the second housing can be fixed to the second fixing member in a seamless connection manner.

[0052] In this embodiment, when a high voltage needs to be supplied to an X-ray tube using a high-voltage power supply, a sufficient amount of silica gel is applied to each of the first connection unit 100 attached to the high-voltage power supply and the second connection unit 200 attached to the X-ray tube, and then the units are inserted. The first and second fixing members are fastened with bolts, and air is expelled from between them to prevent discharge from the high-voltage power supply and secure the high-voltage power supply and the X-ray tube. In the event of a malfunction in the high-voltage power supply or the X-ray tube, the high-voltage power supply and the X-ray tube can be separated simply by removing the bolts on the first and second fixing members and removing the high-voltage power supply from the X-ray tube, facilitating malfunction inspection and maintenance of both the high-voltage power supply and the X-ray tube. Connecting the high-voltage power supply and the X-ray tube in this manner not only reduces the installation volume between the high-voltage power supply and the X-ray tube, but also facilitates disassembly for inspection and repair in the event of a malfunction in either the high-voltage power supply or the X-ray tube.

[0053] Example 3 6 and 7, the first connection unit 100 provided by this embodiment is embedded in the high-voltage power supply housing 1. The first connection unit 100 includes a third fixing member 16 embedded in the high-voltage power supply housing, and the third fixing member 16 is provided with a high-voltage power supply output terminal 4 (corresponding to a plug). After the third fixing member 16 is fitted into the high-voltage power supply housing 1, the space surrounded by the third fixing member 16, the first fixing member 8, and the high-voltage power supply housing 1 is filled with an insulating filler such as high-voltage oil or high-voltage insulating rubber (insulating filler 6 as shown in FIG. 7). Here, the outer end face of the filled insulating filler 6 may be positioned at the same height as the outer end face of the first fixing member 8 of the high-voltage power supply housing 1, or the outer end face of the filled insulating filler 6 may protrude a predetermined distance from the port of the first fixing member 8 of the high-voltage power supply housing 1, or the outer end face of the filled insulating filler 6 may be located inside the port of the first fixing member 8 of the high-voltage power supply housing 1 and spaced a predetermined distance from the outer end face of the first fixing member 8. In addition, the space between the high-voltage module 2 and the high-voltage power supply housing 1 is filled with an insulating filler such as high-voltage oil or high-voltage insulating rubber.

[0054] 7, in this embodiment, a first shield ring 5 may be provided around the outer periphery of the high-voltage power supply output terminal 4 to ensure uniformity of the local electric field. The first shield ring 5 is a metallic shield ring with guide posts made of a metal material. The outer end surface of the first shield ring 5 is positioned at the same height as the outer end surfaces of the insulating filler 6 that fills the space surrounded by the third fixing member 16, the first fixing member 8, and the high-voltage power supply housing 1.

[0055] 7, the high-voltage power supply output terminal 4 serves as the output end of the high-voltage power supply for outputting a predetermined high voltage, and can be connected to the high-voltage module 2 of the high-voltage power supply directly or via a cable 3. Specifically, one end of the high-voltage power supply output terminal 4 can be connected to the high-voltage module 2 of the high-voltage power supply directly or via a cable 3, and the other end of the high-voltage power supply output terminal 4 protrudes from the insulating filler and is located outside the high-voltage power supply housing port for detachable insertion into the second connection unit 200.

[0056] 6 and 8, the second connection unit 200 is embedded in the X-ray source housing 17. The second connection unit 200 includes a fourth fixing member 18 embedded in the X-ray source housing 17, and the fourth fixing member 18 is provided with a power supply input terminal 9 (corresponding to a socket). After the fourth fixing member 18 is fitted into the X-ray source housing 17, the space surrounded by the fourth fixing member 18, the second fixing member 15, and the X-ray source housing 17 is filled with an insulating filler such as high-pressure oil or high-pressure insulating rubber (insulating filler 13 as shown in FIG. 8). Here, when the outer end surface of the insulating filler 6 filled in the space enclosed between the third fixing member 16, the first fixing member 8, and the high-voltage power supply housing 1 is positioned at the same height as the outer end surface of the first fixing member 8, the outer end surface of the insulating filler 13 filled in the space enclosed between the fourth fixing member 18, the second fixing member 15, and the X-ray source housing 17 is positioned at the same height as the outer end surface of the second fixing member 15 in the X-ray source housing 17, thereby ensuring that the end surfaces of the first connection unit 100 and the second connection unit 200 are reliably joined after the high-voltage power supply output terminal 4 is inserted into the power supply input terminal 9.

[0057] When the outer end surface of the insulating filler 6 filling the space enclosed by the third fixing member 16, the first fixing member 8, and the high-voltage power supply housing 1 protrudes a predetermined distance from the port of the first fixing member 8, the outer end surface of the insulating filler 13 filling the space enclosed by the fourth fixing member 18, the second fixing member 15, and the X-ray source housing 17 is located inside the port of the second fixing member 15 in the X-ray source housing 17 and is a predetermined distance away from the outer end surface of the second fixing member 15. This predetermined distance is the same as the predetermined distance by which the outer end surface of the insulating filler 6 protrudes from the port of the first fixing member 8. Therefore, after the high-voltage power supply output terminal 4 is inserted into the power supply input terminal 9, the end surfaces of the first connection unit 100 and the second connection unit 200 can be joined (as shown in FIG. 9 ).

[0058] When the outer end face of the insulating filler 6 filling the space enclosed by the third fixing member 16, the first fixing member 8, and the high-voltage power supply housing 1 is located inside the first fixing member 8 port of the high-voltage power supply housing 1, the outer end face of the insulating filler 13 filling the space enclosed by the fourth fixing member 18, the second fixing member 15, and the X-ray source housing 17 protrudes a predetermined distance from the port of the second fixing member 15. This predetermined distance is the same as the predetermined distance between the outer end face of the insulating filler 6 located inside the first fixing member 8 port and separated from the outer end face of the first fixing member 8. Therefore, after the high-voltage power supply output terminal 4 is inserted into the power supply input terminal 9, the end faces of the first connection unit 100 and the second connection unit 200 can be joined.

[0059] 8, in this embodiment, a second shield ring 10 may be provided around the outer periphery of the power supply input terminal 9 to ensure uniformity of the local electric field. The second shield ring 10 is a metallic shield ring with guide posts made of a metal material. The outer end surface of the second shield ring 10 is located at the same height as the outer end surfaces of the insulating fillers 13 that fill the space surrounded by the fourth fixing member 18, the second fixing member 15, and the X-ray source housing 17.

[0060] 8, the power supply input terminal 9 may be connected directly or via a cable 11 to the cathode of the X-ray tube core 14 as a power supply input terminal for the X-ray tube to receive the required high voltage. Specifically, one end of the power supply input terminal 9 is connected directly or via a cable 11 to the cathode of the X-ray tube core 14, and the other end of the power supply input terminal 9 is embedded in an insulating filler. In addition, by arranging the end face of the other end of the power supply input terminal 9 at the same height as the outer end face of the second shield ring 10, the end faces of the first connection unit 100 and the second connection unit 200 can be joined after the high-voltage power supply output terminal 4 of the first connection unit 100 is inserted into the power supply input terminal 9.

[0061] In this embodiment, as shown in FIG. 9 , when a high voltage needs to be supplied to an X-ray tube using a high voltage power supply, a sufficient amount of silica gel is applied to each of the first connection unit 100 attached to the high voltage power supply and the second connection unit 200 attached to the X-ray tube, and then the units are inserted. Then, bolts are used to fasten the first fixing member 8 and the second fixing member 15, and air is expelled from between them, preventing discharge from the high voltage power supply and securing the high voltage power supply and the X-ray tube. In the event of a malfunction in the high voltage power supply or the X-ray tube, the high voltage power supply and the X-ray tube can be separated simply by removing the bolts from the first fixing member 8 and the second fixing member 15 and disconnecting the high voltage power supply from the X-ray tube, facilitating malfunction inspection and maintenance of both the high voltage power supply and the X-ray tube. Connecting the high voltage power supply and the X-ray tube in this manner not only reduces the installation volume for the high voltage power supply and the X-ray tube, but also facilitates disassembly for inspection and repair in the event of a malfunction in either the high voltage power supply or the X-ray tube.

[0062] Example 4 The structures of the first connection unit 100 and the second connection unit 200 provided in this embodiment differ from those in embodiment 3 in the following respects: the high-voltage power supply and the X-ray tube are connected by inserting the second connection unit 200, to which an X-ray tube is attached, into the first connection unit 100, to which a high-voltage power supply is attached, and the high-voltage power supply and the X-ray tube are separated by pulling out the second connection unit 200 from the first connection unit 100. That is, the first connection unit 100 and the second connection unit 200 provided in embodiment 4 are connected in the opposite manner to that in embodiment 3.

[0063] Specifically, the first connection unit 100 provided by this embodiment differs from the third embodiment in that one end of the high-voltage power supply output terminal 4 can be connected to the high-voltage module 2 of the high-voltage power supply directly or via a cable 3, and the other end of the high-voltage power supply output terminal 4 is embedded in an insulating filler and is positioned at the same height as the outer end surface of the insulating filler. This structure is similar to the structure of the power supply input terminal 9 in the second connection unit 200 provided by the third embodiment shown in Figure 8. Furthermore, after the third fixing member 16 is fitted into the high-voltage power supply housing 1, the space enclosed between the third fixing member 16, the first fixing member 8, and the high-voltage power supply housing 1 is filled with an insulating filler such as high-pressure oil or high-voltage insulating rubber. Here, the outer end surface of the filled insulating filler 6 may be positioned at the same height as the outer end surface of the first fixing member 8 in the high-voltage power supply housing 1, may protrude a predetermined distance from the port of the first fixing member 8 in the high-voltage power supply housing 1, or may be located inside the port of the first fixing member 8 in the high-voltage power supply housing 1 and be separated a predetermined distance from the outer end surface of the first fixing member 8.

[0064] The second connection unit 200 differs from the third embodiment in that one end of the power supply input terminal 9 may be connected to the cathode of the X-ray tube core 14 directly or via a cable 11, and the other end of the power supply input terminal 9 protrudes from the insulating filler and is located outside the X-ray tube housing port. This structure is similar to the structure of the high-voltage power supply output terminal 4 in the first connection unit 100 provided by the third embodiment shown in FIG. 7. Furthermore, after the fourth fixing member 18 is fitted into the X-ray source housing 17, if the outer end surface of the insulating filler 6 filled in the space surrounded by the third fixing member 16, the first fixing member 8, and the high-voltage power supply housing 1 is positioned at the same height as the outer end surface of the first fixing member 8, the outer end surface of the insulating filler 13 filled in the space surrounded by the fourth fixing member 18, the second fixing member 15, and the X-ray source housing 17 is positioned at the same height as the outer end surface of the second fixing member 15 in the X-ray source housing 17, so that after the power supply input terminal 9 is inserted into the high-voltage power supply output terminal 4, the end surfaces of the first connection unit 100 and the second connection unit 200 can be joined.

[0065] When the outer end surface of the insulating filler 6 filling the space enclosed between the third fixing member 16, the first fixing member 8, and the high-voltage power supply housing 1 protrudes a predetermined distance from the port of the first fixing member 8, the outer end surface of the insulating filler 13 filling the space enclosed between the fourth fixing member 18, the second fixing member 15, and the X-ray source housing 17 is located inside the port of the second fixing member 15 in the X-ray source housing 17 and is a predetermined distance away from the outer end surface of the second fixing member 15. This predetermined distance is the same as the predetermined distance by which the outer end surface of the insulating filler 6 protrudes from the port of the first fixing member 8. Therefore, after the power supply input terminal 9 is inserted into the high-voltage power supply output terminal 4, the end surfaces of the first connection unit 100 and the second connection unit 200 can be joined.

[0066] When the outer end surface of the insulating filler 6 filling the space enclosed between the third fixing member 16, the first fixing member 8, and the high-voltage power supply housing 1 is located inside the port of the first fixing member 8 in the high-voltage power supply housing 1, the outer end surface of the insulating filler 13 filling the space enclosed between the fourth fixing member 18, the second fixing member 15, and the X-ray source housing 17 is spaced a predetermined distance from the port of the second fixing member 15. This predetermined distance is the same as the predetermined distance at which the outer end surface of the insulating filler 6 is located inside the port of the first fixing member 8 and is spaced from the outer end surface of the first fixing member 8, thereby ensuring that the end surfaces of the first connection unit 100 and the second connection unit 200 are joined together after the power supply input terminal 9 is inserted into the high-voltage power supply output terminal 4.

[0067] In this embodiment, when high voltage needs to be supplied to the X-ray tube using a high-voltage power supply, a sufficient amount of silica gel is applied to the second connection unit 200 attached to the X-ray tube and the first connection unit 100 attached to the high-voltage power supply, and then they are inserted. The first fixing member 8 and the second fixing member 15 are fastened with bolts, and air is expelled from between them, preventing discharge from the high-voltage power supply and securing the high-voltage power supply and the X-ray tube. In the event of a malfunction in the high-voltage power supply or the X-ray tube, the high-voltage power supply and the X-ray tube can be separated simply by removing the bolts from the first fixing member 8 and the second fixing member 15 and removing the X-ray tube from the high-voltage power supply, facilitating malfunction inspection and maintenance of both the high-voltage power supply and the X-ray tube. Connecting the high-voltage power supply and the X-ray tube in this manner not only reduces the installation volume for the high-voltage power supply and the X-ray tube, but also facilitates disassembly for inspection and repair in the event of a malfunction in either the high-voltage power supply or the X-ray tube.

[0068] The present invention further provides an X-ray source including the above-described connection device. This X-ray source may be configured by connecting a high-voltage power supply and an X-ray tube using the above-described connection device. The high-voltage power supply, X-ray tube, and connection device may exist and be sold independently. Alternatively, the high-voltage power supply and X-ray tube may be connected using the connection device to form an integrated X-ray source and be sold. Here, the structures of the high-voltage power supply and X-ray tube and the operating principles of the X-ray source are conventional, mature technologies, and will not be described again here.

[0069] In summary, the high-voltage power supply and X-ray tube connection device provided by the present invention connects the high-voltage power supply and the X-ray tube by attaching the first connection unit and the second connection unit to the high-voltage power supply and the X-ray tube, respectively, and removably inserting them. Furthermore, the high-voltage power supply and the X-ray tube can be separated, so that if either the high-voltage power supply or the X-ray tube breaks down, they can be disassembled for inspection and repair.

[0070] The above is a detailed description of the high voltage power supply and X-ray tube connection device and the corresponding X-ray source provided by the present invention. Any obvious modifications made to the present invention by those skilled in the art without departing from the essential content of the present invention will fall within the scope of patent protection of the present invention.
