Description

Technical Field

[0001] This utility model relates to the field of insulating frame technology, and in particular to a high-stability insulating frame for current sensors. Background Technology

[0002] In numerous fields such as power systems, industrial automation, and smart homes, current sensors are key components for acquiring current information, and their performance directly affects the operational stability and reliability of the entire system. The insulating frame, as an important part of the current sensor, undertakes crucial functions such as supporting the windings, fixing the magnetic core, and providing electrical insulation.

[0003] In existing technologies, the insulating frame of current sensors typically employs an integral or simply assembled mechanical structure. Integral insulating frames are generally manufactured as a single piece through processes such as injection molding, and their mechanical structure is relatively fixed, with the connection between components relying on the strength of the material itself and the molding process.

[0004] The spliced ​​insulation frame uses welding or screws to connect the various parts. While this method can ensure a certain level of connection strength, it presents many inconveniences during later maintenance.

[0005] When it is necessary to repair, replace or adjust the internal components of a current sensor, welding requires damaging the welding points, which is complicated and can easily damage other components; screw fastening requires disassembling the screws one by one, which is not only time-consuming and laborious, but may also affect the reassembly effect due to problems such as missing screws or stripped threads. To solve the above problems, a high-stability insulating frame for current sensors is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a high-stability insulating frame for current sensors, aiming to improve the problem of inconvenient maintenance in the future caused by the connection of various parts of the insulating frame by welding and screw fastening in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-stability insulating frame for a current sensor includes a frame body one, a frame body two disposed on one side wall of the frame body, a fixing component disposed on one side wall of the frame body, a connecting column fixedly connected inside the frame body one and the frame body two, and a positioning component disposed on the side wall of the connecting column.

[0009] The fixing component includes a positioning rod, which is fixedly connected to one side wall of the frame body. A fixing frame is fixedly connected to one side wall of the frame body. A locking block is slidably connected inside the fixing frame. A limiting block is fixedly connected to one side wall of the locking block. The limiting block is slidably connected inside the fixing frame. A first spring is fixedly connected between the limiting blocks. A positioning hole is opened inside the frame body. The positioning rod is slidably connected inside the positioning hole. A fixing hole is opened inside the frame body. The fixing frame and the locking block are slidably connected inside the fixing hole.

[0010] As a further description of the above technical solution:

[0011] The positioning component includes a connecting frame, which is slidably connected to the side wall of the connecting column. The connecting column has a sliding groove inside, and the sliding groove has a recessed hole inside.

[0012] As a further description of the above technical solution:

[0013] A sliding plate is fixedly connected inside the connecting frame, and the sliding plate is slidably connected inside the slide groove.

[0014] As a further description of the above technical solution:

[0015] The skateboard has a vertical groove inside, and the connecting frame has a second locking block inside;

[0016] As a further description of the above technical solution:

[0017] The second locking block is slidably connected inside the vertical groove, and the second locking block is slidably connected inside the concave hole;

[0018] As a further description of the above technical solution:

[0019] The two side walls of the card block are fixedly connected to the connecting blocks, which are slidably connected inside the vertical groove;

[0020] As a further description of the above technical solution:

[0021] The skateboard is equipped with a second spring, and the connecting post is threadedly connected to the connecting frame with a screw.

[0022] As a further description of the above technical solution:

[0023] One end of the second spring is fixedly connected to the inside of the vertical groove, and the other end of the second spring is fixedly connected to the side wall of the connecting block.

[0024] This utility model has the following beneficial effects:

[0025] 1. In this utility model, the positioning rod is inserted into the positioning hole, and then the fixing frame enters the fixing hole, causing the first locking block to be squeezed and compressed into the fixing frame, which drives the limiting block to squeeze the first spring. After the fixing frame is fully inserted into the fixing hole, the first locking block loses the compression, the first spring rebounds, and the first locking block is locked in the fixing hole, realizing the connection and fixation between the first frame body and the second frame body. This solves the problem of inconvenient maintenance in the later stage when the connection of various parts of the insulating frame is achieved by welding and screw fastening. The above technical solution improves the convenience of assembling the insulating frame.

[0026] 2. In this utility model, when adjustments are needed based on the number of turns and thickness of the winding, the connecting frame is pulled along the side wall of the connecting column, the sliding plate slides in the groove, the second locking block is squeezed into the vertical groove, squeezing the second spring. After the connecting frame is adjusted to the appropriate position, the second locking block falls into the concave hole for initial fixation, and then the connecting frame is fastened to the side wall of the connecting column with screws. This solves the problem that the traditional method often uses a fixed-size winding structure, which cannot flexibly change the winding space. The above technical solution improves the adaptability of the insulating frame to different winding specifications. Attached Figure Description

Detailed Implementation

[0035] 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.

[0036] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a high-stability insulating frame for a current sensor, comprising a frame body 1, a frame body 2 on the side wall of the frame body 1, a fixing component on the side wall of the frame body 1, a connecting post 10 fixedly connected inside the frame body 1 and the frame body 2, and a positioning component on the side wall of the connecting post 10; the fixing component includes a positioning rod 3, which is fixedly connected to the side wall of the frame body 1, a fixing frame 4 fixedly connected to the side wall of the frame body 1, a locking block 5 slidably connected inside the fixing frame 4, a limiting block 6 fixedly connected to the side wall of the locking block 5, the limiting block 6 slidably connected inside the fixing frame 4, a first spring 7 fixedly connected between the limiting blocks 6, the first spring 7 being used for rebound reset, a positioning hole 8 is opened inside the frame body 2, the positioning rod 3 is slidably connected inside the positioning hole 8, a fixing hole 9 is opened inside the frame body 2, and the fixing frame 4 and the locking block 5 are slidably connected inside the fixing hole 9;

[0037] When using this device, the positioning rod 3 serves a positioning function. Aligning it with the positioning hole 8 and inserting it ensures accurate positioning of the frame body 1 and frame body 2 during connection. Then, the fixing frame 4 enters the fixing hole 9, serving as the connection between frame body 1 and frame body 2. The locking block 5 is pressed into the fixing frame 4. At this time, the limiting block 6 compresses the first spring 7. During this process, the first spring 7 stores elastic potential energy. When the fixing frame 4 is fully inside the fixing hole 9, the locking block 5 loses its compression, and the first spring 7 rebounds, locking the locking block 5 inside the fixing hole 9. This locking structure connects and fixes frame body 1 and frame body 2 together, ensuring the overall stability of the insulating frame structure.

[0038] Reference Figure 1 , Figure 5 and Figure 6The positioning component includes a connecting frame 13, which is slidably connected to the side wall of the connecting column 10. The connecting column 10 has a groove 11 inside, and a recess 12 inside the groove 11. A sliding plate 14 is fixedly connected inside the connecting frame 13. The sliding plate 14 is slidably connected inside the groove 11. A vertical groove 15 is opened inside the sliding plate 14. A second locking block 16 is provided inside the connecting frame 13. The recess 12 cooperates with the second locking block 16 to initially fix the connecting frame 13. The second locking block 16 is slidably connected inside the vertical groove 15 and the recess 12. A connecting block 17 is fixedly connected to the side wall of the second locking block 16. The connecting block 17 is slidably connected inside the vertical groove 15. A second spring 18 is provided inside the sliding plate 14. A screw 19 is threadedly connected to the connecting column 10 and the connecting frame 13. One end of the second spring 18 is fixedly connected to the inside of the vertical groove 15, and the other end of the second spring 18 is fixedly connected to the side wall of the connecting block 17.

[0039] When adjustments are needed based on the number of turns and thickness of the winding, the connecting bracket 13 is pulled. The connecting bracket 13 moves the winding space adjustment structure, positioning it against the side wall of the connecting post 10. During this process, the sliding plate 14 slides inside the sliding groove 11. The sliding plate 14 engages with the sliding groove 11 to ensure the smooth movement of the connecting bracket 13. Simultaneously, the second locking block 16 is compressed into the vertical groove 15 as the structure moves, compressing the second spring 18, which stores elastic potential energy. When the connecting bracket 13 is in the correct position, the second locking block 16 re-enters the recess 12 to initially fix the connecting bracket 13. The recess 12 and the second locking block 16 engage to position the connecting bracket 13 in the appropriate location, facilitating further fixing operations. Subsequently, the connecting bracket 13 is fixed to the side wall of the connecting post 10 using screws 19. The tightening action of the screws 19 ensures that the connecting bracket 13 remains stable in the adjusted position, thus meeting the winding space requirements for different numbers of turns and thicknesses of the winding.

[0040] Working principle: When using this device, align the positioning rod 3 with the positioning hole 8 and insert it. Then, the fixing frame 4 enters the fixing hole 9. The locking block 5 is squeezed into the fixing frame 4, causing the limiting block 6 to squeeze the first spring 7. When the fixing frame 4 is fully inserted into the fixing hole 9, the locking block 5 loses its compression, and the first spring 7 rebounds to lock the locking block 5 into the fixing hole 9, so that the frame body 1 and the frame body 2 are connected and fixed together.

[0041] When adjustments are needed based on the number of turns and thickness of the winding, the connecting bracket 13 is pulled to move it to the side wall of the connecting post 10, and the slide plate 14 slides inside the slide groove 11. At the same time, the second locking block 16 is squeezed into the vertical groove 15 as it moves, squeezing the second spring 18. When the connecting bracket 13 is in the correct position, the second locking block 16 re-enters the concave hole 12 to initially fix the connecting bracket 13. Then, the connecting bracket 13 is fixed to the side wall of the connecting post 10 by the screw 19.

[0042] 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.
