Description

Technical Field

[0001] This utility model relates to the field of electromagnetic coil technology, and in particular to an electromagnetic coil frame. Background Technology

[0002] The electromagnetic coil frame is a core supporting component of electrical equipment such as electromagnetic relays, power transformers, micro motors, and sensors. Its core function is to provide axial limiting, insulation isolation, and precise positioning for the coil winding, ensuring that the coil does not shift, loosen, or suffer insulation damage during energized operation, equipment transportation, and vibration environments. This directly affects the electromagnetic performance (such as inductance, impedance, and coupling efficiency) and operational reliability of the electrical equipment.

[0003] However, existing electromagnetic coil frames still have certain defects. For example, most coil frames are made of engineering plastics such as nylon through one-piece injection molding. The retaining ring and the frame are an inseparable whole structure. When the coil needs to be replaced due to insulation aging or wire burning, the coil can only be disassembled by cutting the coil with tools such as utility knives or micro saw blades or by slowly unwinding the copper wire on the coil. However, during the process of cutting the coil, the frame and retaining ring are easily scratched and damaged, affecting subsequent use. Unwinding the copper wire on the coil is labor-intensive and lacks practicality. Utility Model Content

Furthermore, the disassembly of the coil will not damage the inner frame, the first retaining ring, or the second retaining ring, thus increasing the component reuse rate.

[0005] To achieve the above objectives, an electromagnetic coil frame is provided, comprising:

A sliding rod is fixedly connected to the inside of the handle block. A second spring is provided on the outer surface of the sliding rod.

[0007] According to the electromagnetic coil frame described above, the inner surface of the slot is fitted with a pin block.

[0010] According to the electromagnetic coil frame, the inner surface of the limiting groove is slidably connected to the handle block, and the outer surface of the insert block is slidably connected to the second retaining ring.

[0011] According to the electromagnetic coil frame, the outer surface of the limiting circular block is rotatably connected to the handle block, and the outer surface of the trapezoidal plate is slidably connected to the inclined block.

[0012] According to the electromagnetic coil frame, one end of the second spring is fixedly connected to the slider, and the other end of the second spring is fixedly connected to the handle block.

The inner surface of the limiting groove 6 is fixedly connected to the inclined block 18. A slot 19 is provided on the inner surface of the inner frame 1. A slot 20 is provided on the outer surface of the inner frame 1. The inner surface of the slot 19 is adapted to the insert block 17 for easy fixing of the second retaining ring 5. The inner surface of the slot 20 is adapted to the insert block 9 for easy installation of the second retaining ring 5. The outer surface of the inner frame 1 is slidably connected to the second retaining ring 5 for easy installation and removal. The inner surface of the limiting groove 6 is slidably connected to the handle block 8 to limit the movement of the handle block 8. The insert block 9... The outer surface of the trapezoidal plate 13 is slidably connected to the second retaining ring 5, the outer surface of the limiting block 12 is rotatably connected to the handle block 8, the outer surface of the trapezoidal plate 13 is slidably connected to the inclined block 18, one end of the second spring 15 is fixedly connected to the slider 16, the other end of the second spring 15 is fixedly connected to the handle block 8, the outer surface of the trapezoidal plate 13 is slidably connected to the handle block 8, the outer surface of the slider 16 is slidably connected to the handle block 8, the outer surface of the pin block 17 is slidably connected to the handle block 8, and the outer surface of the inclined block 18 is slidably connected to the handle block 8.

[0027] Working principle: When the coil on the inner frame 1 needs to be disassembled and replaced, simply use a hex wrench to turn the internal hex nut 11, driving the threaded rod 10 to move the trapezoidal plate 13 forward along the inclined surface on the inclined block 18. Under the restoring force of the second spring 15 in a compressed state, the pin block 17 is driven to retract into the handle block 8 along the sliding rod 14 under the action of the slider 16, thereby disengaging the pin block 17 from the inside of the slot 19 and releasing the restriction on the handle block 8. Then, push the handle block 8 along the inside of the limiting groove 6 and compress the first spring 7 to release the simplest restriction between the inner frame 1 and the second retaining ring 5. Then, pull out the second retaining ring 5 along the first retaining ring 2 to complete the rest of the second retaining ring 5. Finally, the coil on the inner frame 1 can be directly removed. The disassembly is completed without damaging the coil and the entire coil frame, thus facilitating subsequent use and improving component reuse rate. When the second retaining ring 5 needs to be installed, simply align the positioning block 4 on the second retaining ring 5 with the positioning groove 3 and snap it in. Then, when the insert 9 corresponds to the slot 20, release the handle block 8. Under the rebound force of the first spring 7, the insert 9 will automatically insert into the slot 20, thus completing the installation of the second retaining ring 5. By rotating the internal hex nut 11 in the opposite direction, the trapezoidal plate 13 is driven to move backward along the inclined block 18, which will drive the pin block 17 to extend outward. Under the action of the slider 16, the second spring 15 is compressed, so that the pin block 17 is inserted into the corresponding slot 19, thus completing the limiting and fixing installation of the second retaining ring 5 for subsequent use.
