[0021] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1-4 shown, the present invention provides a terminal connection anti-disconnection interface, including an interface body 1. A set of installation grooves 2 are opened at the top of the interface body 1. The inner walls of the set of installation grooves 2 are all movably inserted with pressure rods 3. Pressure blocks 4 are fixedly sleeved on the outer walls of the set of pressure rods 3. First springs 5 are movably sleeved on the outer walls of the set of pressure rods 3. L-shaped plates 6 are fixedly installed at the bottoms of the set of pressure rods 3. First fixing blocks 7 are fixedly installed at the tops of the set of L-shaped plates 6. A mounting bracket 8 is fixedly installed at the bottom of the interface body 1. Two first chutes 9 are opened on the inner wall of the mounting bracket 8. Slide blocks 10 are slidably embedded in the inner walls of the two first chutes 9. A pushing plate 11 is fixedly connected between the outer walls of one side of the two slide blocks 10. A set of jacking rods 12 are fixedly installed at the top of the pushing plate 11. Second springs 13 are movably sleeved on the outer walls of the set of jacking rods 12. Second fixing blocks 14 are fixedly installed at the tops of the set of jacking rods 12.

[0024] The effect achieved by the entire Embodiment 1 is as follows. First, when the pressing rod 3 is pressed, the pressing rod 3 will move downward. This action simultaneously drives the L-shaped plate 6 and the first fixing block 7 to move downward synchronously. During the downward pressing of the pressing rod 3, the pressing block 4 will squeeze the first spring 5, causing it to deform and store elastic potential energy. Subsequently, the terminal is inserted into the inside of the interface body 1. At this time, the pressing rod 3 is released, and the elastic potential energy stored due to the previous compression of the first spring 5 begins to be released. Its restoring force acts on the first fixing block 7, causing the first fixing block 7 to move upward. This action will prompt the first fixing block 7 to tightly clamp the inserted terminal, achieving preliminary fixation. Next, by rotating the fixing screw 17, using its threaded engagement relationship with the threaded groove 18, the push plate 11 can be driven to move upward along the axial direction of the threaded groove 18. The upward movement of the push plate 11 will further drive a set of ejector rods 12 to rise synchronously, and the rise of the ejector rods 12 will push the second fixing block 14 upward. This series of actions realizes the secondary clamping or fixation of the terminal, enhancing the stability of the terminal inside the interface body 1. Through this unique connection method, the terminal inside the interface body 1 undergoes two fixation processes. Such a design not only ensures a stable and reliable connection between the terminal and the interface body 1, but also improves the stability and durability of the entire connection structure. Moreover, this connection method simplifies the installation process, improves work efficiency, and makes the connection between the terminal and the interface body 1 more convenient, efficient, and safe.

[0025] Embodiment 2 is as Figures 2-4 shown. A slot hole 15 is formed in the bottom of the push plate 11. A bearing 16 is fixedly inserted into the inner wall of the slot hole 15. A fixing screw 17 is fixedly inserted into the inner wall of the bearing 16. A threaded groove 18 is formed in the bottom of the mounting frame 8, and the outer wall of the fixing screw 17 is threadedly connected to the inner wall of the threaded groove 18. Two second sliding grooves 19 are formed in the inner wall of the interface body 1. Slide bars 20 are slidably embedded in the inner walls of the two second sliding grooves 19. A baffle 21 is fixedly connected between the outer walls of the two slide bars 20. A push block 22 is fixedly installed on one side of the outer wall of one group of baffles 21. Three third springs 23 are fixedly installed on the top of one group of baffles 21.

[0026] The effect achieved by the entire embodiment 2 is that when the terminal interface outside the interface body 1 is not in use, the baffle 21 acts as an effective protective barrier, which can significantly prevent external dust, moisture and other debris from entering the interface, thereby protecting the interface from contamination and damage, and ensuring the performance and reliability of the interface in future use. When the terminal needs to be inserted to establish a connection, the user only needs to simply pull the push block 22 upward. This action will drive the baffle 21 to move vertically upward. At the same time, the rise of the baffle 21 will squeeze the three third springs 23, causing them to deform and store elastic potential energy. As the baffle 21 is completely removed, the terminal interface is exposed, allowing the user to insert the terminal smoothly. When the terminal completes its task and is pulled out and is no longer in use, the three third springs 23 will use their previously stored elastic potential energy to automatically reset, push the baffle 21 down to its original position, and re-close the terminal interface, thereby providing continuous protection for the interface.

[0027] Working principle: When in use, the staff first presses the corresponding pressure rod 3. The downward movement of the pressure rod 3 will drive the L-shaped plate 6 and the first fixed block 7 to move downward synchronously. During this process, the pressure block 4 will act on the first spring 5, causing it to be squeezed and store elastic potential energy. Then, the push block 22 is pulled upward. This action will prompt the baffle 21 to move upward in the vertical direction, thereby exposing the terminal interface and making it accessible. At the same time, the precise cooperation of the two second slide grooves 19 and the two slide bars 20 is used to ensure the stability and accuracy of the baffle 21 during movement. The rise of the baffle 21 will also squeeze the three third springs 23 below it, causing them to deform and store energy. Subsequently, a group of terminals are accurately inserted into the terminal structure corresponding to the interface body 1. At this time, the pressure rod 3 is released, and the elastic force released by the first spring 5 due to the previous compression will push the first fixed block 7 to move upward. , thereby achieving a preliminary and firm clamping of the inserted terminals. By repeating the above-mentioned operation method, multiple terminals can be inserted into the terminal interface corresponding to one side of the outer wall of the interface body 1 in turn. After completing the preliminary fixation, rotate the fixing screw 17. Utilizing the threaded cooperation principle of the fixing screw 17 and the threaded groove 18, rotating the fixing screw 17 will drive the push plate 11 to move upward along the axial direction. The upward movement of the push plate 11 is further guaranteed by the firm cooperation of the two first slide grooves 9 and the two sliders 10, ensuring the stability and accuracy of the movement of the push plate 11. The rise of the push plate 11 will simultaneously drive a group of ejector rods 12 to move upward, and a group of ejector rods 12 will then respectively push a group of second fixing blocks 14 to move upward synchronously, thereby achieving secondary tightening and clamping of multiple terminals. Through this double clamping connection method, the terminals inside the interface body 1 are firmly fixed twice, thereby significantly improving the stability and reliability of the connection.

Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
