Example Embodiment
[0034] The invention is like image 3 As shown, the iron core 1 and the floating coil 2 are included. The core 1 is mainly composed of a chip 11 and an end plate 12. There are key grooves 14 on both sides of the chip 11, and the corresponding positions on both sides of the end plate 12 are also provided with key grooves 14. The numerous chips 11 and the end plates 12 at both ends are connected into an integral pin key 13, and an insulating liner 17 is also provided between the pin key 13 and the key groove 14 (see Figure 6 ) To prevent the chip 11 from forming short-circuit contacts. The cross-sectional shape of the keyway 14 and the matching pin 13 can be as follows Pic 4-1 Rectangle (including square), or Figure 4-2 The chevron, or Figure 4-3 The two ends shown are curved, or any geometric shape that can ensure the chip is tightly fixed. Screws are used at both ends of the end plate 13 to fix the chips 11 and the two end plates 13 into one body. The levitation coil 2 located...
