[0015] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] The present invention will now be further described with reference to the accompanying drawings.

[0017] This utility model provides the following technical solution: As attached Figure 1-3 As shown, an anti-detachment surge arrester includes a main body 1 and a cable 2. The main body 1 includes a housing 3 and a power connection structure 4. The housing 3 is provided with an input port 5 and an output port 6. A power connection channel 7 is opened inside the housing 3, and the power connection structure 4 is arranged inside the power connection channel 7. The input port 5 is located at the upper end of the housing 3, and the output port 6 is located at the bottom of the housing 3. One end of the power connection structure 4 is located in the input port 5, and the other end is located in the output port 6. The power connection structure 4 is electrically connected to the cable 2 through the output port 6. The characteristic feature is that the housing 3 is also provided with an anti-detachment device 8, which is located on the side of the housing 3 away from the output port 6. The anti-detachment device 8 secures the connection of the main body 1. In this embodiment, the function of the anti-detachment device 8 is to enhance the stability between the main body 1 and the connecting parts, preventing accidental detachment due to external environmental factors. The design of the anti-detachment device 8 fully considers the safety and reliability requirements of surge arresters in practical applications. Through a precise mechanical structure, it ensures that the surge arrester can maintain a stable connection under various harsh conditions, thereby effectively avoiding safety hazards caused by the detachment of the surge arrester.

[0018] Furthermore, the housing 3 is provided with an anti-detachment groove 9, and an anti-fall-off device 8 is provided in the anti-detachment groove 9. The anti-fall-off device 8 includes a control end 10, a spring 11, a connecting rod 12, a support rod 13, a transmission assembly 14, and a limiting strip 15. A baffle 16 is also provided in the anti-detachment groove 9. The control end 10 and the connecting rod 12 are respectively provided on both sides of the baffle 16. The baffle 16 is provided with a connection hole corresponding to the position of the control end 10. The connecting rod 12 passes through the connection hole and connects to the control end 10. The connecting rod 12 is located away from the control end 10. A spring 11 is fitted on one side of the device. One end of the spring 11 is connected to the connecting rod 12, and the other end of the spring 11 abuts against the baffle 16. The end of the connecting rod 12 away from the control end 10 is connected to the support rod 13. The connecting rod 12 drives one end of the support rod 13 to move. The end of the support rod 13 away from the connecting rod 12 is connected to the transmission assembly 14. The end of the transmission assembly 14 away from the support rod 13 is connected to the limiting strip 15. The support rod 13 drives the transmission assembly 14 to move towards and away from the power connection channel 7. In this embodiment, the anti-detachment device 8 functions to allow the connecting rod 12 and the support rod 13 to return to their original positions via elastic force when subjected to pushing or pulling forces, thereby enhancing the device's self-adaptive capability. When it is necessary to fix the surge arrester to the connecting component, the operator can push the connecting rod 12 through the control terminal 10. The connecting rod 12 drives one end of the support rod 13 to move towards the transmission assembly 14 until the support rod 13 abuts against the transmission assembly 14. The transmission assembly 14 then transmits the force of the support rod 13 to the limiting strip 15, so that the limiting strip 15 is firmly connected to the connecting component to achieve an anti-detachment effect. At this time, the spring 11 is in a stretched state, providing a continuous thrust to the connecting rod 12 and the support rod 13 to ensure the stability of the connection. At the same time, the anti-detachment groove 9 provides a stable moving track, so that the support rod 13 can maintain linear movement during movement, avoiding deviation or tilting, thereby further improving the stability and reliability of the connection.

[0019] Furthermore, the transmission assembly 14 includes a transmission bar 17 and a rotating member 18. One side of the rotating member 18 is fixedly connected to the housing 3, and the other side of the rotating member 18 is rotatably mounted on the transmission bar 17. One side of the transmission bar 17 is connected to the support rod 13, and the other side of the transmission bar 17 is connected to the limiting strip 15. The rotating member 18 drives both ends of the transmission bar 17 to reciprocate in the direction of approaching and moving away from the power connection channel 7. In this embodiment, the function of the transmission assembly 14 is to convert the outward force of the support rod 13 into the reciprocating motion of the limiting strip 15, thereby achieving a stable connection with the connecting component. Specifically, when the operator pushes the connecting rod 12 through the control terminal 10, the connecting rod 12 drives one end of the support rod 13 to move towards the transmission bar 17. The support rod 13 pushes one end of the transmission bar 17, causing the other end of the transmission bar 17 to drive the limiting strip 15 to move towards the connecting component until the limiting strip 15 is in close contact with the connecting component, achieving a stable connection. At this time, the rotating component 18 rotates on the transmission bar 17 to accommodate its movement. When the external force disappears, the elasticity of the spring 11 causes the connecting rod 12 and the support rod 13 to return to their original positions, and the transmission bar 17 also resets. The limiting bar 15 maintains a stable connection with the connecting components, effectively preventing the surge arrester from falling off. This design not only improves the safety and reliability of the surge arrester but also makes it easier for operators to install and remove it.

[0020] Furthermore, the limiting strip 15 is formed on the outer wall of the housing. The limiting strip 15 has a connecting part 19 and a fixing part 20. The connecting part 19 extends into the housing 3 and is fixedly connected to the housing 3. Guide slopes 21 are respectively provided on both sides of the fixing part, and the guide slopes 21 on both sides are symmetrically arranged. The side of the connecting part 19 away from the input hole 5 is connected to the transmission strip 17. The transmission strip 17 pushes one end of the connecting part 19 to move away from the power connection structure 4. One end of the limiting strip 15 is fixedly connected to the housing 3, and the other end is connected to the moving block, forming a stable connection structure. In this embodiment, the design of the limiting strip 15 further enhances the stability and reliability of the anti-detachment device 8. When the support rod 13 pushes against the moving block to move, the transmission component 14 will drive the limiting strip 15 to move together, providing a continuous thrust to the limiting strip 15, ensuring that the limiting strip 15 can fit tightly against the connecting component and prevent the surge arrester from falling off. In addition, the design of the guide ramps 21 on both sides can guide the movement direction of the limit strip 15, so that the limit strip 15 can move more smoothly, further improving the stability and reliability of the connection. At the same time, the guide ramp 21 on the side away from the connecting component can also press down on the limit strip 15 when the product is detached from the connecting component, avoiding the situation where the limit strip 15 is inconvenient to detach after it is fixed.

[0021] Furthermore, the anti-detachment device 8 also includes a self-locking component 22, which includes a self-locking cover 23 and a self-locking buckle 24. One end of the self-locking buckle 24 is fixedly mounted on the baffle 16, and the other end is movably mounted on the side wall of the control end 10. The control end 10 is also provided with a positioning slot 25. When the control end 10 pushes the connecting rod 12 to prevent detachment, the self-locking buckle 24 extends into the positioning slot 25 to complete self-locking. In this embodiment, the function of the self-locking component 22 is to ensure that after the anti-detachment device 8 is opened, the control end 10 of the anti-detachment device 8 can still maintain the opening of the anti-detachment device 8 when there is no external force continuously pushing it. The self-locking cover 23 protects the control terminal 10 located on the outside of the surge arrester after the anti-detachment device 8 is opened, and ensures that the control terminal 10 will not close itself due to external force. The connection between the self-locking cover 23 and the housing 3 can be a snap-fit ​​connection or other connection methods. In this embodiment, the positioning slot 25 includes a locking part 26 located in the side wall of the control terminal 10 and a return part 27 protruding from the side wall. The locking part 26 allows the self-locking buckle 24 to extend into the control terminal 10 and limit the movement of the control terminal 10, ensuring that the anti-detachment device 8 will not fail due to the return of the control terminal 10 when it is fixed. The return part 27 ensures that the self-locking buckle 24 can pass over the locking part 26 and return to its original position when the anti-detachment device 8 is closed.

[0022] Furthermore, the power connection structure 4 includes a power connection terminal 28 and a discharge terminal 29. One end of the power connection terminal 28 and the discharge terminal 29 are electrically connected. The power connection terminal 28 and the discharge terminal 29 are arranged perpendicularly. The end of the power connection terminal 28 away from the discharge terminal 29 is located inside the input hole 5, and the end of the discharge terminal 29 away from the power connection terminal 28 is located inside the output hole 6. In this embodiment, the power connection terminal 28 and the discharge terminal 29 intersect within the power connection channel 7. The power connection terminal 28 is located inside the input hole 5 and extends into the connecting component for electrical connection. The discharge terminal 29 is located at the lower end of the main body and is connected to the cable 2. When current flows through, the power connection terminal 28 receives the current and conducts it to the discharge terminal 29, while the discharge terminal 29 transmits the current to the cable 2 to complete the current conduction. The design of the power connection terminal 28 and the discharge terminal 29 fully considers the efficiency and safety of current transmission. Through reasonable layout and structural design, the stability and safety of the current during transmission are ensured. Meanwhile, the materials of the connecting terminal 28 and the discharging terminal 29 have been carefully selected, possessing excellent conductivity and corrosion resistance, ensuring stable performance during long-term use. Furthermore, the connection method between cable 2 and the discharging terminal 29 has been optimized to ensure a robust and reliable connection, avoiding current transmission problems caused by poor connections. In summary, this surge arrester is designed with various practical application requirements in mind. Through a precise mechanical structure and reasonable electrical design, it ensures stable connection and safe operation under various harsh conditions, providing strong protection for the safe and stable operation of the power system.
