Technical Field
[0001] This utility model relates to the technical field of arc-proof module high-voltage output terminal structure, specifically an arc-proof module high-voltage output terminal structure. Background Technology
[0002] With the continuous improvement of economic level, high voltage power supplies have been widely used. High voltage power supplies generally refer to power supplies with an output voltage of more than 5,000 volts. They have many uses, mainly including high voltage power supplies for lasers, high voltage power supplies for semiconductor manufacturing equipment, and high voltage power supplies for spectral analysis. In the process of using high voltage power supplies, the high voltage output is achieved through the conversion of connectors.
[0003] A search revealed a Chinese patent publication number: CN217086930U, which provides an insulating housing, an input terminal housing, and an output terminal housing. Both ends of one side of the output terminal housing are provided with sealing structures. An output terminal body is installed on one side of the output terminal housing, an input terminal housing is provided on one side of the output terminal body, an input terminal body is installed on one side of the input terminal housing, and both ends of one side of the input terminal housing are provided with reinforcing structures.
[0004] Although the aforementioned patent can tightly fit the terminal body by clamping the terminal, the aforementioned terminal housing still has the following problems: when the output terminal and the input terminal are connected, the device is only positioned and fixed by the engagement of the locking block and the locking slot, making the connection method of the device relatively simple and unable to properly fix the output housing and the input housing. If the housing is not firmly fixed, it may cause insufficient contact pressure between the internal pins and the socket, resulting in increased contact resistance, causing signal attenuation or interruption. Long-term looseness will also accelerate pin wear or oxidation, exacerbating the problem of poor contact. In view of the above, technical innovation is carried out on the basis of the existing device. Utility Model Content

[0023] Please see Figures 1-5This utility model provides a technical solution: an arc-resistant module high-voltage output terminal structure, including an output terminal housing 1 and an input terminal housing 2. An output terminal 19 is installed inside the output terminal housing 1, and an input terminal 20 is installed inside the input terminal housing 2. The surface of the output terminal 19 is inserted into the interior of the input terminal 20. The surface of the output terminal 19 has a chrome-plated layer. The chrome layer is designed to resist arc erosion during arc discharge, preventing burning or melting. A fixing post 6 is provided at the top of the output terminal housing 1. The surface of the fixing post 6 extends movably through the interior of the output terminal housing 1 and to the exterior. A disc 5 is fixedly connected to the top of the fixing post 6. A U-shaped sliding groove 7 is provided inside the output terminal housing 1. A base plate 18 is fixedly connected to the bottom of the fixing post 6. The surface of the base plate 18 is slidably connected to the interior of the sliding groove 7. A first spring is fixedly connected to the bottom of the base plate 18. Spring 9, the side of the first spring 9 away from the base plate 18 is fixedly connected to the inside of the slide groove 7. The first spring 9 can be reset and compressed by the up and down movement of the base plate 18. A transmission rod 8 is rotatably connected to the bottom of the base plate 18. A push block 10 is rotatably connected to the side of the transmission rod 8 away from the base plate 18. The transmission rod 8 is set in an inclined position inside the slide groove 7. The inclination of the transmission rod 8 allows the transmission rod 8 to move more smoothly when the base plate 18 moves downward, and prevents the device from jamming. A T-shaped groove 12 is opened inside the output terminal housing 1. The inside of the T-shaped groove 12 is connected to the inside of the slide groove 7. A T-shaped block 11 is fixedly connected to the bottom of the push block 10. The surface of the T-shaped block 11 is slidably connected to the inside of the T-shaped groove 12. Since the cross-sections of the T-shaped block 11 and the T-shaped groove 12 are both T-shaped, the movement direction of the push block 10 is restricted, and the push block 10 can move more smoothly.
[0024] The output terminal housing 1 has a transmission groove 15 inside, and a second spring 14 is fixedly connected inside the transmission groove 15. A limit post 16 is rotatably connected inside the transmission groove 15, and a fixing rod 13 is fixedly connected to the surface of the limit post 16. The fixing rod 13 has an L-shaped cross-section and a bevel on one side. The surface of the fixing rod 13 is slidably connected to the inside of the transmission groove 15. The side of the second spring 14 near the fixing rod 13 is fixedly connected to the surface of the fixing rod 13. The input terminal housing 2 has an L-shaped groove 17 inside, and the surface of the L-shaped groove 17 is slidably connected to the surface of the fixing rod 13. By using the inclined surface on the fixed rod 13, as the fixed rod 13 slides into the L-shaped groove 17, the input terminal housing 2 can push the fixed rod 13 to rotate through the L-shaped groove 17, and stretch the second spring 14. When the fixed rod 13 slides into the appropriate position inside the L-shaped groove 17, the second spring 14 returns to its original position, causing the longitudinal rod of the fixed rod 13 to slide into the longitudinal groove of the L-shaped groove 17, thus fixing the positions of the output terminal housing 1 and the input terminal housing 2. This makes the installation of the output terminal housing 1 and the input terminal housing 2 more convenient, and allows the operator to use the device more easily.
[0025] The top of the output terminal housing 1 is fixedly connected to the outer frame 3. Inside the outer frame 3, a rotating plate 4 is rotatably connected via a torsion spring and a shaft. The torsion spring and shaft enable the rotating plate 4 to rotate more smoothly. The rotating plate 4 is in its initial vertical state. When the rotating plate 4 is in a horizontal state, the torsion spring is compressed, which allows the triangular block 21 to block and limit the input terminal housing 2. The bottom of the rotating plate 4 is fixedly connected to the triangular block 21. The triangular block 21 can make the output terminal housing 1 and the input terminal housing 2 fit more tightly, preventing poor contact of the terminals. In the vertical state, the rotating plate 4 can protect the output terminal 19 and reduce the impact of objects in the external environment on the output terminal 19 to a certain extent, thereby extending the service life of the output terminal 19.
[0026] Working principle: For this type of arc-proof module high-voltage output terminal structure, when the operator needs to connect the output terminal 19 and the input terminal 20, first press the disc 5, causing the base plate 18 at the bottom of the fixed column 6 to push the transmission rod 8, which in turn drives the push block 10 to move under the restriction of the T-slot 12 and the T-block 11. The push block 10 pushes the fixed rod 13 to rotate under the restriction of the limit post 16. When the fixed rod 13 rotates to the appropriate angle, it is inserted into the L-shaped groove 17, simultaneously connecting the output terminal 19 and the input terminal 20. Then, release the disc 5, causing the second spring 14 to push the fixed rod 13 to rotate, causing the fixed rod 13 to engage with the L-shaped groove 17. At the same time, the output outer frame 3 rotates on one side. The rotating plate 4, through a torsion spring and a shaft, allows for smoother rotation. When the rotating plate 4 is in a vertical position (initial state), the torsion spring is compressed when it is in a horizontal position, causing the triangular block 21 to block and limit the input terminal housing 2. This ensures tight contact between the terminals, reduces contact resistance fluctuations, and prevents signal interruption or power loss due to vibration or external force. Furthermore, when the output terminal 19 and input terminal 20 are separated, the rotating plate 4 can rotate downwards to shield the output terminal 19, protecting it from external contaminants that could affect the conductivity of subsequent connections and blocking potential discharge paths.
