Existing high-voltage sockets typically use a cylindrical socket body. When high voltage is applied, a large electric field strength exists at the connection point between the socket body and the electrode ring, potentially leading to discharge breakdown and posing a significant safety hazard. There is currently no effective shielding method to address this issue. Summary of the Invention

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0027] The terms "first," "second," etc., used in the specification and claims of this utility model are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this utility model can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] High-voltage socket 1 in the prior art Figure 1 As shown, the socket body 2 has a cylindrical structure. The socket body 2 has a conical hole inside, and the plug of the high-voltage cable can be inserted into the conical hole. The socket body 2 mainly serves as insulation. The diameter of the socket body 2 at the connection between the socket body 2 and the electrode ring 3 is small. The electric field strength at this connection is large, which may pose a risk of discharge breakdown. There is currently no good shielding method.

[0029] In view of the technical problems existing in the high-voltage socket 1 in the prior art, this utility model embodiment proposes a high-voltage socket 100.

[0030] The following is combined with Figure 2 The high-voltage socket 100 provided in this utility model embodiment will be described in detail through specific embodiments and application scenarios.

[0031] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0032] The high-voltage socket 100 according to an embodiment of the present utility model is used to cooperate with a high-voltage cable plug. The high-voltage socket 100 includes a socket body 10, an extension 20, a first electrode ring 30, and a second electrode ring 40.

[0033] Specifically, the socket body 10 is formed as a columnar insulating member, and a receiving cavity is defined within the socket body 10 extending axially and open at one end, the receiving cavity being used to receive a high-voltage cable plug; the extension 20 is formed as an annular insulating member, the extension 20 is sleeved on the outer wall surface of the socket body 10 near one end, and the inner periphery of the extension 20 is connected to the outer wall surface of the socket body 10; the first electrode ring 30 is sleeved on the extension 20, the inner wall surface of the first electrode ring 30 is connected to the outer periphery of the extension 20, the first electrode ring 30 is used to connect the ground end of the high-voltage cable plug; the second electrode ring 40 is connected to the other end of the socket body 10 to connect the high-voltage end of the high-voltage cable plug.

[0034] In other words, according to the high-voltage socket 100 of this utility model embodiment, the first electrode ring 30 is welded to the socket body 10, and the electric field strength is relatively large near the weld 21 formed at the connection. An extension 20 is provided on the outer periphery of the socket body 10, the extension 20 protruding from the surface of the socket body 10, and the extension 20 is similar to a disc. Figure 2 As shown, the diameter of the extension 20 is larger than the maximum diameter of the socket body 10, thereby increasing the distance between the weld 21 and the high-voltage cable plug, reducing the electric field strength at the weld position, and increasing the length of the outer edge surface between the two ends of the socket body 10, thus improving the insulation capability of the first electrode ring 30.

[0035] Therefore, according to the embodiment of the present utility model, the high-voltage socket 100, by providing an extension portion 20 in the circumferential direction of the socket body 10, can reduce the electric field strength near the weld 21 between the first electrode ring 30 and the socket body 10, improve the insulation capability of the first electrode ring 30, and improve the high-voltage resistance performance of the high-voltage socket 100.

[0036] According to one embodiment of the present invention, the socket body 10 and the extension 20 are integrally molded parts. The integrally molded parts have a stable structure and only require slight modifications to the original model of the socket body 10, making them easy to process.

[0037] Preferably, one end of the second electrode ring 40 is sleeved on the other end of the socket body 10 and welded to the other end of the socket body 10. The second connecting ring 40 facilitates the installation of other components on the socket body 10.

[0038] In one embodiment of this utility model, the socket body 10 and the extension 20 are coaxially arranged. Specifically, the axial cross-sections of the extension 20 and the socket body 10 are axisymmetric, resulting in a uniform electric field distribution and high stability.

[0039] Optionally, the surface of the extension 20 facing the side where the second electrode ring 40 is located is inclined in the radial direction of the socket body 10 in a direction away from the location of the second electrode ring 40.

[0040] In other words, such as Figure 2 As shown, Figure 2 The upper surface of the extension 20 extends downward at an angle, forming an inclined surface. This structure facilitates the uniform application of a high-voltage resistant coating, such as chromium oxide, to the upper surface of the extension 20 and the outer wall of the socket body 10, thereby further improving the high-voltage resistance. Furthermore, a chamfer can be formed at the connection between the extension 20 and the socket body 10 for ease of processing.

[0041] According to another embodiment of the present invention, the outer periphery of the extension 20 and the inner wall surface of the first electrode ring 30 define an annular gap 22 on the side facing the second electrode ring 40, thereby improving the insulation capability of the first electrode ring 30.

[0042] Furthermore, the axial dimension of the annular gap 22 is larger than the radial dimension of the annular gap 22. For example... Figure 2 As shown, a deep groove structure is adopted between the extension 20 and the first electrode ring 30 to further improve the insulation performance of the first electrode ring 30.

[0043] Preferably, the two ends of the first electrode ring 30 along its axial direction are respectively higher than the two ends of the extension 20 along its axial direction, which facilitates assembly.

[0044] The X-ray generator according to the second aspect of the present invention includes the high-voltage socket 100 described in the above embodiment. Since the high-voltage socket 100 according to the present invention has the advantages of high voltage resistance and strong insulation performance, the X-ray generator according to the present invention also has the advantages of high voltage resistance and strong insulation performance.

[0045] Other structures and techniques of the X-ray generator according to the embodiments of this utility model are prior art and will not be described in detail here.

[0046] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
