Abstract

The present invention relates to the field of joint design, and particularly to a vacuum high-voltage quick-connect joint, which includes an insulating tube and a vacuum box body. The body of the insulating tube is fixedly passed through the box wall of the vacuum box body. The inner end of the insulating tube extends into the interior of the vacuum box body, and a copper joint is inserted at the inner end opening. The outer end of the insulating tube extends to the outside of the vacuum box body, and a fixed socket for inserting a high-voltage plug is sleeved at the outer end opening.

[0001] The present invention relates to the field of joint design, and particularly to a vacuum high-voltage quick-connect joint. Background Art

[0002] Currently, when manufacturing equipment such as X-ray tubes, high-voltage electricity needs to be provided for the equipment. The equipment is placed in a vacuum chamber, the joint is fixed on the wall of the vacuum chamber, and the plug of the high-voltage cable is inserted and mated with the joint to achieve high-voltage power supply for the equipment. The joint structure in the prior art is complex and the processing cost is high. Summary of the Invention

[0003] The object of the present invention is to overcome the defects existing in the above-mentioned prior art, and provide a vacuum high-voltage quick-connect joint, which has a simple structure, a relatively low processing cost, and is convenient and fast to use.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a vacuum high-voltage quick-connect joint, including an insulating tube and a vacuum chamber body. The body of the insulating tube is transversely fixed in the wall of the vacuum chamber body. The inner end of the insulating tube extends into the interior of the vacuum chamber body, and a copper joint is inserted at the inner end opening of the insulating tube. The outer end of the insulating tube extends to the outside of the vacuum chamber body, and a fixed socket for inserting a high-voltage plug is sleeved at the outer end opening of the insulating tube. The insulating tube and the vacuum chamber body are hermetically mated, and the inner end opening of the insulating tube and the copper joint are hermetically mated. After the high-voltage plug is inserted into the fixed socket, it passes through the inside of the insulating tube and is inserted into the inner end of the copper joint to achieve high-voltage power-on. The outer end of the copper joint supplies power to the equipment through a cable, and the fixed socket is grounded.

[0005] A guiding tube is vertically fixed on the outer side wall of the vacuum chamber body. One end of the guiding tube is communicated with the vacuum chamber body, and the other end of the guiding tube is welded with a first flange. The fixed socket is fixedly connected to the outer end opening of the insulating tube by thread connection, and the fixed socket is connected and fixed to the first flange through a second flange.

[0006] The outer end face of the insulating tube is in a stepped shape. One end of the fixed socket is a cylindrical insertion tube for inserting the high-voltage plug, and the other end face of the fixed socket is in a stepped shape. The stepped end face of the fixed socket and the stepped end face of the insulating tube are abutted and fixedly connected by thread connection. The cylindrical insertion tube is communicated with the insulating tube. A first flange is provided on the outer periphery of the fixed socket. The second flange is welded to one of the shaft ends of the hollow stepped shaft, and a second flange is provided at the other shaft end of the hollow stepped shaft. The hollow stepped shaft is sleeved outside the fixed socket and the insulating tube, and the end face of the fixed socket abuts against the inner step of the hollow stepped shaft. The first flange and the second flange are abutted and connected by bolts.

[0007] Beneficial effects: When this application is in use, the device is placed inside the vacuum chamber. The outer end of the copper joint and the device are electrically connected through a cable. When power supply is required, the external high-voltage plug is directly inserted into the fixed socket. The inner end of the high-voltage plug can pass through the inside of the insulating tube and then contact the copper joint to conduct electricity, thereby realizing power supply to the device. The structure of the entire quick-connect joint is relatively simple, which reduces the processing cost and is convenient and fast to use. Brief Description of the Drawings

[0008] Figure 1 is a schematic structural diagram of the present invention; Detailed Embodiments

[0009] The following combines Figure 1 to further describe the present invention.

[0010] A vacuum high-voltage quick-connect joint includes an insulating tube 10 and a vacuum chamber 20. The body of the insulating tube 10 is horizontally fixed through the wall of the vacuum chamber 20. The inner end of the insulating tube 10 extends into the vacuum chamber 20 and a copper joint 30 is inserted at the inner end pipe orifice. The outer end of the insulating tube 10 extends outside the vacuum chamber 20 and a fixed socket 40 for inserting a high-voltage plug is sleeved at the outer end pipe orifice. The insulating tube 10 and the vacuum chamber 20 are in sealing fit. The inner end pipe orifice of the insulating tube 10 and the copper joint 30 are in sealing fit. After the high-voltage plug is inserted into the fixed socket 40, it passes through the inside of the insulating tube 10 and is inserted into the inner end of the copper joint 30 to realize high-voltage power supply. The outer end of the copper joint 30 supplies power to the device through a cable, and the fixed socket 40 is grounded. When this application is in use, the device is placed inside the vacuum chamber 20. The outer end of the copper joint 30 and the device are electrically connected through a cable. When power supply is required, the external high-voltage plug is directly inserted into the fixed socket 40. The inner end of the high-voltage plug can pass through the inside of the insulating tube 10 and then contact the copper joint 30 to conduct electricity, thereby realizing power supply to the device. The structure of the entire quick-connect joint is relatively simple, which reduces the processing cost and is convenient and fast to use.

[0011] Further, a guiding tube 50 is vertically fixed on the outer side wall of the vacuum chamber 20. One end of the guiding tube 50 communicates with the vacuum chamber 20, and the other end of the guiding tube 50 is welded with a first flange 60. The fixed socket 40 is fixedly connected to the outer end pipe orifice of the insulating tube 10 through a threaded connection. The fixed socket 40 is fixedly connected to the first flange 60 through a second flange 70, thus realizing the fixation of the fixed socket 40 and the insulating tube 10.

[0012] Preferably, the outer end face of the insulating tube 10 is stepped. One end of the fixed socket 40 is a cylindrical insertion tube 41 for inserting a high-voltage plug. The other end face of the fixed socket 40 is stepped. The stepped end face of the fixed socket 40 and the stepped end face of the insulating tube 10 are in abutting cooperation and are fixed by threaded connection. The cylindrical insertion tube 41 communicates with the insulating tube 10. A first flange 42 is provided on the outer periphery of the fixed socket 40. The second flange 70 is welded to one end of the hollow stepped shaft 80. A second flange 90 is provided at the other end of the hollow stepped shaft 80. The hollow stepped shaft 80 is sleeved outside the fixed socket 40 and the insulating tube 10, and the end face of the fixed socket 40 abuts against the inner step of the hollow stepped shaft 80. The first flange 42 and the second flange 90 are in contact and are connected by bolts. When inserting the high-voltage plug, although the high-voltage plug will squeeze the fixed socket 40, due to the abutting cooperation between the stepped end face of the fixed socket 40 and the stepped end face of the insulating tube 10, the stepped end face of the insulating tube 10 will give a resilience to the fixed socket 40 to prevent the axial movement of the fixed socket 40 when it is squeezed, ensuring the stability of the whole structure and prolonging the service life of the whole quick-connect joint.

[0013] It should be understood that the specific embodiments described above are only used to explain the present invention and are not used to limit the present invention. Obvious changes or variations derived from the spirit of the present invention are still within the protection scope of the present invention.
