Description

Technical Field

[0001] This utility model relates to the field of equipotential isolators, and in particular to an equipotential isolator. Background Technology

[0002] An equipotential bonding device is a specialized protective device for grounding systems, primarily composed of nonlinear elements. Under normal operating conditions, the two ends of the bonding device are independent of each other. During a lightning strike, the nonlinear characteristics of the equipotential bonding device limit the surge amplitude, dissipate its energy, and form a transient equipotential connection, thus meeting the requirements for protecting the equipment.

[0003] Traditional isolators often use fixed-size installation structures, which can only be adapted to installation points with specific spacing. This often leads to installation difficulties due to mismatched mounting holes, increasing installation costs and operational complexity. In addition, the internal wiring of isolators often relies on a single terminal or bolt for fixation. When the equipment is affected by external factors such as vibration and temperature changes, the cables are prone to loosening, resulting in poor contact, and may even cause safety hazards such as increased resistance and overheating. Therefore, an equipotential isolator is used to solve these problems. Utility Model Content

[0032] 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.

[0033] Reference Figures 1-5This utility model provides an embodiment of an equipotential isolator, comprising an isolator body 1, which serves as the core supporting structure of the entire device, housing and protecting all internal electrical components. A circuit board 2 is fixedly connected to the top side of the isolator body 1. The circuit board 2 is the core control component for achieving equipotential isolation, integrating various electronic components and circuits. A connecting rod 3 is fixedly connected to the top of the circuit board 2, serving as a connection node between the circuit board 2 and external cables, used to connect external cables to the corresponding circuits on the circuit board 2 to achieve electrical signal transmission. A sealing cover 4 is hinged to the top of the isolator body 1, and the sealing cover 4 can rotate and open around the hinge point, sealing the interior of the isolator body 1 when closed. To prevent dust, moisture and other impurities from entering and affecting the performance of the components, and to facilitate internal wiring and maintenance when opened, the isolator body 1 is fixedly connected to the left and right sides with lead pipes 5. The lead pipes 5 are used to guide external cables into and out of the isolator body 1, and play a role in protecting and limiting the cables. The bottom of the isolator body 1 is fixedly connected to the mounting plate 6. The mounting plate 6 is used to fix the isolator body 1 to the external mounting surface. The top left and right sides of the mounting plate 6 are provided with mounting holes 7 distributed front and back. The mounting holes 7 are used to pass through bolts and other fasteners. The bottom rear side of the mounting plate 6 is fixedly connected to the fixing plate 8. The fixing plate 8 serves as a fixed support point at the bottom of the mounting plate 6 and cooperates with the telescopic component to form an installation structure. The telescopic component is installed at the bottom of the mounting plate 6.

[0034] The telescopic assembly includes a second fixed plate 9, which is slidably connected to the bottom of the mounting plate 6. The second fixed plate 9 is the core moving part of the telescopic assembly, cooperating with the first fixed plate 8 to achieve installation. Telescopic sliders 10 are fixedly connected to the top left and right sides of the second fixed plate 9. The telescopic sliders 10 serve as the connection medium between the second fixed plate 9 and the mounting plate 6, driving the second fixed plate 9 to slide along the bottom of the mounting plate 6. The telescopic sliders 10 are T-shaped, and the T-shaped structure can engage with the telescopic limiting groove 11 at the bottom of the mounting plate 6 to prevent the telescopic sliders 10 from detaching from the mounting plate 6 during sliding. Limiting blocks 12 are fixedly connected to the left and right sides of the rear end of the telescopic sliders 10, and the limiting blocks 12 are used to restrict the sliding of the telescopic sliders 10. The telescopic slider 10 has a fixed stroke to prevent it from sliding too far forward and disengaging from the telescopic limit groove 11. A spring 13 is fixedly connected to the rear side of the telescopic slider 10. The spring 13 provides a restoring force through its own elastic deformation. A baffle 14 is fixedly connected to the rear side of the bottom of the mounting plate 6. The baffle 14 is used to limit the backward sliding limit of the telescopic slider 10. Telescopic limit grooves 11 are opened on both the left and right sides of the bottom of the mounting plate 6. The telescopic slider 10 is slidably connected in the telescopic limit groove 11. The limit block 12 is slidably connected in the telescopic limit groove 11. The other end of the spring 13 is fixedly connected to the rear end of the telescopic limit groove 11. The telescopic limit groove 11 provides a sliding track for the telescopic slider 10, limits its sliding direction, and ensures the stable operation of the telescopic assembly.

[0035] Reference Figure 1 , Figure 4 and Figure 5 Inside the isolator body 1, on the top side, are fixedly connected left and right distributed cable fixing blocks 15. The cable fixing blocks 15 support the cables to be fixed, and their tops provide a support surface for the cables. Together with the cable fixing plate 18, they clamp and fix the cables. Inside the isolator body 1, on the top side, are fixedly connected left and right distributed limit rods 16. The limit rods 16 guide the lifting and lowering movement of the cable fixing plate 18. Inside the isolator body 1, on the top side, are fixedly connected left and right distributed limit bases 22. The limit bases 22 fix the limit threaded rods 17, providing stable rotational support and ensuring that the limit threaded rods 17 do not shift during rotation. The limit threaded rods 17 are rotatably connected inside the limit bases 22. The limit threaded rods 17 drive the cable fixing plate 18 to move up and down through rotation, adjusting the degree of cable clamping. The cable fixing plate 18 is slidably connected to the outer periphery of the limit rods 16. A rubber pad 21 is fixedly connected in the middle, and the rubber pad 21 abuts against the top side of the cable fixing block 15. The cable fixing plate 18 drives the rubber pad 21 to move up and down under the guidance of the limiting rod 16, and cooperates with the cable fixing block 15 to clamp the cable and prevent the cable from loosening. The rubber pad 21 has elasticity and friction. When it comes into contact with the cable, it can not only avoid the cable being damaged by being clamped hard, but also enhance the friction on the cable and improve the fixing effect. A lifting hole 19 is opened at the front of the cable fixing plate 18, and the limiting rod 16 is slidably connected in the lifting hole 19. The lifting hole 19 provides a passage for the limiting rod 16 to pass through, so that the cable fixing plate 18 can slide smoothly along the limiting rod 16. A threaded hole 20 is opened at the rear of the cable fixing plate 18, and the outer circumference of the limiting threaded rod 17 is threadedly connected in the threaded hole 20. The threaded hole 20 and the outer circumference of the limiting threaded rod 17 are engaged, converting the rotational motion of the limiting threaded rod 17 into the linear motion of the cable fixing plate 18.

[0036] Working principle: When installing the equipotential isolator, the telescopic assembly achieves flexible adaptation of the installation position through elastic sliding. When it is necessary to adjust the distance between the second fixed plate 9 and the first fixed plate 8 to match different installation positions, pulling the second fixed plate 9 will cause the telescopic slider 10 at its top to slide backward along the telescopic limiting groove 11 at the bottom of the mounting plate 6. At this time, the spring 13 on the rear side of the telescopic slider 10 is stretched and stores elastic potential energy. The limiting block 12 at the rear end of the telescopic slider 10 slides synchronously along the telescopic limiting groove 11 to prevent the telescopic slider 10 from leaving the track. When the second fixed plate 9 is released, the tension of the spring 13 pushes the telescopic slider 10 to return to its original position. Through this process, the distance between the second fixed plate 9 and the first fixed plate 8 can be flexibly adjusted, and stable fixation can be achieved without additional adapters.

[0037] When wiring inside the isolator, the cable is passed through the lead tube 5 and placed on top of the fixing block 15. Rotating the limiting threaded rod 17 inside the limiting base 22 causes the limiting threaded rod 17 to engage with the threaded hole 20 at the rear of the fixing plate 18. Since the front of the fixing plate 18 slides along the limiting rod 16 through the lifting hole 19, the rotational motion of the limiting threaded rod 17 is converted into the vertical downward movement of the fixing plate 18. The rubber pad 21 at the bottom of the fixing plate 18 moves down and gradually presses the cable on top of the fixing block 15. The elastic deformation of the rubber pad 21 can prevent the cable from being damaged by hard compression and can also enhance the fixing effect through friction. When the limiting threaded rod 17 is rotated in the opposite direction, the fixing plate 18 moves upward, allowing the cable to be loosened for replacement or adjustment, ensuring the stability of the wiring.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
