Description

Technical Field

[0001] The utility model relates to the technical field of iron cores, and more specifically, to a cast aluminum sealed ultra-microcrystalline iron core. Background Art

[0002] Ultra-microcrystalline ferromagnetic materials are a new type of magnetic materials, whose magnetic properties are much higher than those of traditional silicon steel sheets. Therefore, they have broad application prospects in electromagnetic devices such as motors and transformers. Ultra-microcrystalline ferromagnetic materials have excellent properties such as low loss, high magnetic permeability, and high saturation magnetic induction intensity, and can significantly improve the efficiency and performance of devices.

[0003] Since there are certain risks without solid sealing, for the ultra-microcrystalline iron cores used in epoxy resin casting structures, when there is a slight deviation in the buffer layer treatment, resin often penetrates into the iron core, resulting in large fluctuations in the error of the mutual inductor, thus failing to meet the required accuracy of the product.

[0034] An embodiment of the present application discloses a cast aluminum sealed super-microcrystalline iron core, including a cast aluminum sealed housing 1, and a fixing component is installed inside the cast aluminum sealed housing 1;

[0035] The fixing component includes a fixed column 2, the top of the fixed column 2 is fixedly connected to a hydraulic rod 3, the top of the hydraulic rod 3 is fixedly connected to a sliding column 4, a plurality of first fixing strips 5 are fixedly connected to the outside of the sliding column 4, two push rods 6 are fixedly connected to the outside of each of the plurality of first fixing strips 5, a second fixing strip 7 is installed inside one end of each of the plurality of push rods 6, a fixing ring 8 is fixedly connected to one side of each of the plurality of second fixing strips 7, a sliding rod 9 is fixedly connected to the bottom of each of the plurality of fixing rings 8, and a first chute 10 matching the sliding rod 9 is arranged at the bottom of the inner cavity of the cast aluminum sealed housing 1. By using the mounting plate 16 to squeeze the sliding column 4 downward, the sliding column 4 squeezes the hydraulic rod 3 to move downward, thereby driving the plurality of push rods 6 to move outward, and the plurality of push rods 6 all push the fixing ring 8 to expand outward through the second fixing strip 7, so that the plurality of fixing rings 8 can support and fix the inside of the super-microcrystalline iron core body 11.

[0036] Refer to Figure 5As shown, super-microcrystalline core bodies 11 are installed on the outer sides of multiple fixing rings 8. An installation plate 12 is arranged at the bottom end of the super-microcrystalline core body 11. Multiple second sliding grooves 13 are formed on the top surface of the installation plate 12. A sliding hole 14 is formed in the middle of the top end of the installation plate 12. Multiple sliding rods 9 slide inside the second sliding grooves 13, facilitating the support of the multiple fixing rings 8 to support and fix the inner side of the super-microcrystalline core body 11. The sliding hole 14 allows the sliding column 4 to telescopically move inside the cast aluminum sealing shell 1.

[0037] Referring to Figure 3 and 4 As shown, a first sealing ring 15 is installed on the outer side of the top end of the super-microcrystalline core body 11. An installation plate 16 is fixedly connected to the top of the first sealing ring 15. Multiple second sealing rings 17 are fixedly connected to the front side of the installation plate 16. Fixing screws 18 are installed inside the multiple second sealing rings 17. Fixing screw holes 19 are installed on the outer sides of the bottom ends of the multiple fixing screws 18.

[0038] Referring to Figure 1 As shown, a protection plate 20 is installed on the outer side of the super-microcrystalline core body 11. Multiple buffer grooves 21 are formed inside the protection plate 20.

When the installation plate 16 is closed, it will drive the first sealing ring 15 to fit on the top of the super-microcrystalline iron core body 11, facilitating the protection of the top of the super-microcrystalline iron core body 11. When the plurality of fixing screws 18 drive the installation plate 16 to move downward, the middle part of the bottom end of the installation plate 16 presses downward on the sliding column 4, causing the sliding column 4 to press downward on the hydraulic rod 3 through the sliding hole 14, so that the sliding column 4 can move downward. While the sliding column 4 moves downward, one end of a plurality of first fixing bars 5 is movably connected to the outer side of the push rod 6, enabling a plurality of first fixing bars 5 to push the push rod 6 to move outward. By using the other ends of a plurality of push rods 6 to be movably connected to the outer side of the second fixing bar 7, a plurality of push rods 6 can push the fixing ring 8 to move outward through the second fixing bar 7. A plurality of fixing rings 8 drive the bottom ends of the sliding rods 9 to slide inside the first sliding grooves 10, and the plurality of first sliding grooves 10 provide a guiding function for the movement of the fixing rings 8, facilitating the outward expansion of a plurality of fixing rings 8 inside the super-microcrystalline iron core body 11, enabling the super-microcrystalline iron core body 11 to be stably fixed and enhancing the stability inside the super-microcrystalline iron core body 11.
