Description

Technical Field

[0001] The invention relates to the technical field of high-voltage power feeding, and in particular to a high-voltage socket which can be used as a high-voltage feeding component. Background Art

[0002] The high-voltage feed-in assembly is a basic component of high-voltage devices. Traditional high-voltage feed-in assemblies often do not match the high-voltage plug of the power supply and are prone to loosening, requiring a separate high-voltage socket to be connected. Existing commercial high-voltage sockets usually use organic materials and sealing ring structures. Due to their materials, structures, etc., they cannot adapt to the vacuum, high temperature and other environments where high-voltage devices work, and cannot be directly assembled in high-voltage devices. Summary of the invention

[0003] The purpose of the present invention is to provide a high-voltage socket that can be used as a high-voltage feed-in assembly to solve the problem that the traditional high-voltage feed-in assembly often does not match the high-voltage plug of the power supply, is easy to loosen, and needs to be connected to a high-voltage socket.

[0004] The present invention is achieved through the following technical solutions:

[0005] A high-voltage socket that can be used as a high-voltage feed-in component comprises a socket body, a socket hole is formed at one end of the socket body, the socket body is made of insulating ceramic, a lower ring, an upper ring, and an insulating ceramic sheet are sequentially arranged in the socket hole in a direction away from the socket hole, the insulating ceramic sheet and the upper ring are wrapped with a connecting ring and fixed to the socket body, crown springs are respectively arranged in the rings of the upper ring and the lower ring, the central axes of the crown spring, the upper ring and the lower ring coincide with the central line of the socket hole, and also comprises a spring sheet, a short pin, and a long pin, the spring sheet and the crown spring are fixed by screws, one end of the short pin serves as a first electrode connection end, and the other end passes through the insulating ceramic sheet to be connected to the spring sheet, and one end of the long pin serves as a second electrode connection end, and the other end passes through the insulating ceramic sheet to be connected to the lower ring. Furthermore, the present invention designs a novel high-voltage socket, in which the short pin and the long pin are connected to the power line as the first electrode connection end and the second electrode connection end respectively, and the connecting ring is connected to the upper ring and introduced into the vacuum device as the third electrode connection end; when the high-voltage plug is inserted into the socket, the elasticity of the crown spring inside the lower ring and the upper ring is utilized to closely contact the upper and lower ring poles of the corresponding plug respectively; the elasticity of the spring sheet is utilized to ensure that the screw fixed on the spring sheet is in close contact with the center pole of the corresponding plug; in this way, the corresponding plug can be closely connected to the high-voltage socket and effectively prevented from loosening, thereby solving the problem that the traditional high-voltage feed-in component is often not matched with the high-voltage plug of the power supply, is easy to loosen, and needs to be connected to another high-voltage socket.

[0006] The outer surface of the socket body is provided with a plurality of annular grooves, which are evenly arranged along the axial direction of the socket body, and the center line of each annular groove coincides with the center line of the jack. Furthermore, the annular grooves are distributed in circles on the outer surface of the socket body, so that the outer surface of the socket body forms a bellows structure, and the bellows has a smaller axial stiffness and a larger radial stiffness, which enables the bellows to produce a larger telescopic deformation displacement under the same load, and can improve the surface pressure resistance of the outer surface of the socket body, can adapt to an environment with a larger pressure change, and improve the reliability of the present invention.

[0007] Preferably, the socket body has a radial length of 20 to 200 mm, an axial length of 50 to 400 mm, and a number of annular grooves of 15 to 30.

[0008] A flange is also provided at one end of the socket body near the jack port, and a mounting screw hole is provided on the flange. Further, the mounting screw hole on the flange is designed to match the flange of the corresponding plug, so as to ensure that the present invention and the corresponding joint are convenient and reliable to install, and the flange and the corresponding high-voltage device can be connected by brazing or welding to ensure airtightness.

[0009] The flange, the connection ring and the socket body, the long pin, the short pin and the insulating ceramic sheet are all brazed and sealed after ceramic metallization. Furthermore, ceramic metallization is to firmly adhere a layer of metal film on the surface of the ceramic to achieve welding between the ceramic and the metal; the flange, the connection ring and the socket body, the long pin, the short pin and the insulating ceramic sheet are brazed and sealed to ensure the insulation between the electrodes and the reliability of the airtightness of the sealing between the above.

[0010] Preferably, the jack is a tapered hole, wherein the inner diameter of the jack increases linearly toward the jack opening. Further, the size of the jack is designed according to the size of the plug to be installed, and the inner diameter of the jack increases linearly toward the jack opening, so that the jack near the spring sheet and the crown spring can exert radial extrusion force on the plug, thereby improving the stability of the connection between the two.

[0011] Preferably, the taper of the jack is 2° to 15°, and the diameter of the jack opening is 10 to 180 mm, which is suitable for most plug sizes.

[0012] An insulating porcelain ring is also arranged between the upper ring and the lower ring, and the two end faces of the insulating porcelain ring are in contact with the end faces of the upper ring and the lower ring respectively. Further, the upper ring and the lower ring are separated by the insulating porcelain ring, which ensures that the three poles are insulated from each other and ensures airtightness.

[0013] The connecting ring and the upper ring are connected as one body by fusion welding. The connecting ring and the upper ring are connected by fusion welding such as argon arc welding as one pole and introduced into the vacuum device to ensure the airtightness of the connection.

[0014] Preferably, the lower ring, upper ring, connecting ring, long pin and short pin are made of 4J34 alloy. The thermal expansion coefficient of 4J34 alloy is close to that of ceramics, and has advantages such as excellent conductivity, which can ensure the reliability of excellent conductivity and airtight sealing of the present invention.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0016] 1. The present invention provides a high-voltage socket that can be used as a high-voltage feed-in assembly. The entire structure solves the problem that the traditional high-voltage feed-in assembly often does not match the high-voltage plug of the power supply, is easy to loosen, and needs to be connected to a high-voltage socket;

[0017] 2. The present invention provides a high-voltage socket that can be used as a high-voltage feed-in component. The high-voltage socket is isolated by an insulating porcelain ring and made of materials such as 4J34 alloy to make the lower ring, upper ring, connecting ring, long pin, short pin, etc., so that the high-voltage socket has better air tightness and stronger insulation reliability, and can adapt to vacuum, high temperature, complex radiation and ion bombardment environments;

[0018] 3. The high-voltage socket of the present invention can be used as a high-voltage feed-in component. The ceramic and other materials and the sealing processes such as brazing are used to ensure that the high-voltage socket can still work normally when baked at more than 500°C during the exhaust period of the high-voltage device, thereby improving the vacuum degree of the entire high-voltage device and ensuring the long-term working stability of the high-voltage device.
