Description

Technical Field

[0001] This utility model relates to the field of X-ray high voltage generator technology, specifically to a plug containing a cable for an X-ray high voltage generator. Background Technology

[0002] The main function of the high-voltage generator is to supply high DC voltage to the cathode and anode of the X-ray tube and the filament heating voltage. It mainly consists of a power supply circuit, a high-voltage circuit, a filament circuit, a control circuit, an application equipment circuit, and a housing that encapsulates the above circuits. The high-voltage circuit connects the high-voltage generator to the X-ray tube via a plug.

[0003] The existing X-ray high-voltage generator uses a cable plug that connects to the socket on the generator and X-ray tube via a terminal block on the plug. However, the existing terminal block is exposed and easily damaged by impact. Moreover, the existing plug body and socket are simply plugged and unplugged, which can easily be accidentally unplugged, causing high-voltage leakage and posing a safety risk. Summary of the Invention

[0004] I. Technical problems to be solved

[0005] The technical problem this invention aims to solve is that the exposed terminals are easily damaged by impacts; the simple plug-in connection between the plug body and the socket makes it easy for the plug to be accidentally pulled out, leading to high-voltage leakage and posing a safety risk.

[0006] I. Technical problems to be solved

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a plug containing a cable for an X-ray high-voltage generator, comprising a high-voltage cable and a plug body connected to both ends of the high-voltage cable, wherein a plurality of terminals are connected to the plug body, a socket is connected to the high-voltage generator, and a socket is connected to the socket for engaging with the terminals, a protective cylinder for protecting the terminals is slidably connected to the plug body, and a locking component for locking the plug body and the socket is connected to the protective cylinder.

[0008] A fixing ring is connected to the plug body. Several sliding grooves are connected to the plug body circumferentially on the side away from the terminal block from the fixing ring. A sliding ring is slidably connected to the plug body. Several springs are connected between the sliding ring and the fixing ring. A slider is connected to the sliding ring and slides in cooperation with the sliding groove. An annular groove is connected to the sliding ring. A connecting ring is connected to the protective cylinder and slides in cooperation with the annular groove. First, the protective cylinder is slid backward, which drives the sliding ring. The sliding ring slides backward along the direction of the sliding groove through the sliding cooperation of the slider and the sliding groove, avoiding the protective cylinder from blocking the terminal block and facilitating the connection of the terminal block on the plug body with the socket hole on the socket.

[0009] Furthermore, the locking assembly includes a first limiting block and a second limiting block connected to the inner wall of the protective cylinder. There are two second limiting blocks, which are respectively disposed on both sides of the first limiting block. Both the first limiting block and the second limiting block are arc-shaped structures with different arc lengths. A limiting ring is connected to the socket. The limiting ring has a first through hole and a second through hole circumferentially opposite each other. The first through hole cooperates with the first limiting block, and the second through hole cooperates with the second limiting block. First, the first limiting block is aligned with the first through hole and the second limiting block is aligned with the second through hole, so that the first limiting block on the protective cylinder passes through the first through hole and the second limiting block passes through the second through hole. Then, the protective cylinder is rotated to drive the first limiting block and the second limiting block so that the first through hole no longer cooperates with the first limiting block. Thus, the limiting ring on the socket limits and locks the first limiting block.

[0010] Furthermore, the protective cylinder is connected to the first limiting block with a first standard groove, and the socket is connected to the first through hole with a second standard groove. When unlocking is required, the protective cylinder needs to be driven to rotate until the first standard groove and the second standard groove are aligned. At this time, the first limiting block and the first through hole cooperate, and the second through hole and the second limiting block cooperate, so that the plug body and the protective cylinder can be pulled out.

[0011] Furthermore, the protective cylinder is provided with several anti-slip textures in its circumferential connection, which improves the friction of the protective cylinder through the coordinated arrangement of the anti-slip textures.

[0012] Furthermore, the plug body is provided with a flexible anti-bend head at the connection point with the high-voltage cable. The anti-bend head is circumferentially connected with an array of arc grooves. The anti-bend head with arc grooves facilitates the protection of the end of the high-voltage cable and prevents cracking during use.

[0013] III. Beneficial Effects

[0014] The advantages of this utility model compared with the prior art are: the protective sleeve can shield and protect the terminal block, preventing damage to the terminal block; the locking component facilitates the locking of the plug body and the socket, preventing the safety risk of high voltage leakage caused by accidental unplugging of the plug body during high voltage cable connection.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Combined with appendix Figure 1 and Figure 4 A plug for an X-ray high-voltage generator, comprising a high-voltage cable 1 and a plug body 2 connected to both ends of the high-voltage cable 1, wherein the plug body 2 is provided with a plurality of terminals 3, the high-voltage generator is provided with a socket 4, the socket 4 is provided with a socket 5 that mates with the terminals 3, a protective cylinder 6 is slidably connected to the plug body 2 to protect the terminals 3, the protective cylinder 6 is provided with a plurality of anti-slip textures around its circumference, a fixing ring 7 is connected to the plug body 2, a plurality of sliding grooves 8 are connected to the side of the plug body 2 away from the terminals 3 around the fixing ring 7, a sliding ring 9 is slidably connected to the plug body 2, a plurality of springs 10 are connected between the sliding ring 9 and the fixing ring 7, a slider 11 is connected to the sliding ring 9 and slides with the sliding grooves 8, an annular groove is connected to the sliding ring 9, and a connecting ring is connected to the protective cylinder 6 and slides with the annular groove.

[0023] The protective cylinder 6 in the above structure allows the protective cylinder 6 to shield and protect the terminal 3 under the action of the spring 10, preventing the terminal 3 from being damaged by collision.

[0024] Combined with appendix Figure 2 ,Figure 3 and Figure 4 The protective cylinder 6 is equipped with a locking assembly that can lock the plug body 2 and the socket 4. The locking assembly includes a first limiting block 12 and a second limiting block 13 connected to the inner wall of the protective cylinder 6. The protective cylinder 6 is provided with a first standard groove 17 at the first limiting block 12. There are two second limiting blocks 13, which are respectively located on both sides of the first limiting block 12. Both the first limiting block 12 and the second limiting block 13 are arc-shaped structures with different arc lengths. The socket 4 is equipped with a limiting ring 14. The limiting ring 14 is provided with a first through hole 15 and a second through hole 16 circumferentially opposite each other. The first through hole 15 cooperates with the first limiting block 12, and the second through hole 16 cooperates with the second limiting block 13. The socket 4 is provided with a second standard groove 18 at the first through hole 15.

[0025] The locking component in the above structure is designed to facilitate the positioning of the limiting ring 14 on the socket 4 and the first limiting block 12 and the second limiting block 13 on the plug body 2, thereby preventing the plug body 2 from being accidentally pulled out.

[0026] Example 2

[0027] Based on Example 1, combined with Appendix Figure 1 The plug body 2 is provided with a flexible anti-bend head 19 at the connection point with the high-voltage cable 1, and the anti-bend head 19 is provided with an annular array of arc grooves in the circumferential direction.

[0028] The anti-bend head in the above structure helps to extend the service life of the high-voltage cable 1.

[0029] The specific usage method is as follows:

[0030] First, slide the protective cylinder 6 backward. The anti-slip texture increases the friction of the protective cylinder 6. The protective cylinder 6 drives the slip ring 9. The slip ring 9 slides backward along the direction of the slip groove 8 through the sliding engagement of the slider 11 and the slip groove 8. This prevents the protective cylinder 6 from blocking the terminal 3, making it easier to mate the terminal 3 on the plug body 2 with the socket 5 on the socket 4, thereby achieving the mating of the plug body 2 and the socket 4.

[0031] The locking assembly facilitates the locking of the plug body 2 and the socket 4. Then, the first limiting block 12 is aligned with the first through hole 15 and the second limiting block 13 is aligned with the second through hole 16, so that the first limiting block 12 on the protective cylinder 6 passes through the first through hole 15 and the second limiting block 13 passes through the second through hole 16. Then, the protective cylinder 6 is rotated to drive the first limiting block 12 and the second limiting block 13 so that the first through hole 15 no longer engages with the first limiting block 12. As a result, the limiting ring 14 on the socket 4 limits and locks the first limiting block 12, thus preventing the plug body 2 from being accidentally pulled out during the connection of the high-voltage cable 1, which could cause a high-voltage leakage and pose a safety risk.

[0032] When unlocking is required, the protective cylinder 6 needs to be rotated until the first standard slot 17 and the second standard slot 18 are aligned. At this time, the first limiting block 12 engages with the first through hole 15, and the second through hole 16 engages with the second limiting block 13, so that the plug body 2 and the protective cylinder 6 can be pulled out.
