Description

Technical Field

[0001] The utility model belongs to the technical field related to inductors, and particularly relates to an anti-falling NR magnetic rubber inductor. Background Art

[0002] NR magnetic inductors are electronic components that convert electrical energy into magnetic energy and store it. Their operating principle is based on Faraday's law of electromagnetic induction, which states that when current passes through a wire, it generates a magnetic field around it. Changes in this magnetic field induce an electromotive force within the coil, which resists changes in current. NR magnetic inductors have a structure similar to a transformer, but typically have only one winding. Their fundamental characteristic is that they resist changes in current, particularly alternating current, while their resistance to direct current is relatively small. However, during operation, the inductor generates high temperatures inside, affecting its performance and posing a safety hazard to the normal operation of the circuit. Utility Model Content

[0025] The utility model provides Figure 1-4 shown

[0026] An anti-falling NR magnetic rubber inductor comprises an upper magnetic conductive block 1, an iron core 2 is provided below the upper magnetic conductive block 1, the top of the iron core 2 is fixedly connected to the bottom of the upper magnetic conductive block 1, a lower magnetic conductive block 3 is provided below the iron core 2, the top of the lower magnetic conductive block 3 is fixedly connected to the bottom of the iron core 2, a heat dissipation component is located inside the upper magnetic conductive block 1, and the heat dissipation component is used to conduct heat generated during the operation of the inductor to reduce the impact of heat on the performance of the inductor and ensure the normal operation of the circuit. The heat dissipation component includes a heat conducting sheet 9 and a heat dissipation ring block 12; a coil 4, which is wound around the iron core 2, the coil 4 is used to generate a magnetic field when current passes through, and the outer side of the coil 4 is wrapped with a magnetic glue layer 5; the pad 6 is located at the bottom of the lower magnetic conductive block 3, and the top of the pad 6 is fixedly connected to the bottom end of the lower magnetic conductive block 3. The bottom of the pad 6 is provided with two left and right lead guide grooves 7, the openings of the two lead guide grooves 7 face downward and the two lead guide grooves 7 are respectively wound around the two ends of the coil 4, and an insulating block 8 is provided in the middle of the pad 6. The insulating block 8 separates the pad 6 from the middle, and the two lead guide grooves 7 are respectively located on both sides of the insulating block 8. The insulating block 8 is used to perform two-stage separation to avoid short circuit. When in use, the coil 4 is first evenly wound on the iron core 2, and then the two ends of the coil 4 are respectively wound on the two lead guide grooves 7 on the welding pad 6, and then the coil 4 is wrapped and protected with a magnetic glue layer 5. Then, the inductor is welded to the circuit to be installed through the welding pad 6 for connection. During operation, the current will pass through the head end of the coil 4 in the lead guide groove 7, pass through the coil 4 wound on the iron core 2, and then flow out from the end of the coil 4 in the other lead guide groove 7. When the current passes through the coil 4 wound on the iron core 2, a magnetic field will be generated around it, thereby forming electrical energy storage. When the current changes, this magnetic field will change, thereby inducing voltage on the coil 4.

[0027] like Figure 2As shown, multiple heat-conducting plates 9 are embedded in the side of the core 2. The length of the heat-conducting plates 9 is consistent with the length of the core 2. The multiple heat-conducting plates 9 are evenly distributed on the side of the core 2. When the coil 4 is wound on the core 2, the heat generated by the current passing through the inner side of the coil 4 is transferred to the multiple heat-conducting plates 9. The bottom of the upper magnetic block 1 is recessed inward to form a cavity 10. The top of the core 2 is fixedly connected to the top of the cavity 10. A heat-conducting ring plate 11 is provided at the bottom end of the cavity 10. The heat-conducting ring plate 11 is sleeved on the core 2. The inner side of the heat-conducting ring plate 11 is fixedly connected to the side of the core 2. At this time, the heat-conducting plates 9 are partially in contact with the heat-conducting ring plate 11. The heat of the heat-conducting plates 9 will be transferred to the heat-conducting ring plate 11, and the heat at the top of the coil 4 will be transferred to the heat-conducting ring plate 11. The heat-conducting ring plate 11 is flush with the bottom end of the upper magnetic block 1. A heat dissipation ring block 12 is provided above the heat conducting ring sheet 11.

The heat dissipation fins 13 are evenly fixedly connected to the top of the heat dissipation ring block 12. The heat of the heat conducting sheet 9 and the heat conducting ring sheet 11 will be transferred to the heat dissipation ring block 12, and the heat will be dissipated through the heat dissipation ring block 12 and the heat dissipation fins 13. Figure 1 and Figure 2 As shown, the top of the upper magnetic block 1 is provided with multiple through-type heat dissipation vents 14. These vents 14 are connected to the cavity 10, allowing heat within the cavity 10 to flow out through the vents 14. A polyester mesh 15 is provided on top of the vents 14. The polyester mesh 15 has good air permeability and can also filter fine dust particles, preventing foreign matter from clogging the vents 14. During use, when the inductor is energized, the internal temperature generated by the inductor is transferred to the heat dissipation ring block 12 by the heat conductive sheet 9 and the heat conductive ring sheet 11. The heat generated by the coil 4 being energized is then dissipated by the heat dissipation ring block 12 and the heat dissipation fins 13 within the cavity 10, and ultimately discharged through the heat dissipation vents 14. This arrangement further enhances the inductor's heat dissipation performance, reduces the impact of heat on the inductor's performance, and ensures the normal operation of the circuit.

[0028] like Figure 1 and Figure 3 As shown, a nylon cloth strip 16 is provided on the outside of the upper magnetic block 1, and a conductive coating 17 is provided on the inside of the nylon cloth strip 16. The conductive coating 17 can form a shielding layer to reduce the influence of external electromagnetic interference. A wear-resistant layer 18 is provided on the outside of the nylon cloth strip 16. The wear-resistant layer 18 can protect and extend the service life of the magnetic layer 5. The nylon cloth strip 16 wraps the side of the inductor. Figure 3As shown, both ends of the nylon cloth strip 16 are provided with fixing blocks 19, and the two fixing blocks 19 are fixedly connected to the two ends of the nylon cloth strip 16. The two fixing blocks 19 are provided with multiple threaded holes 20, and screws 21 are screwed into the threaded holes 20. By wrapping the nylon cloth strip 16 around the inductor and then overlapping the two fixing blocks 19, the screws 21 are tightened into the threaded holes 20 to fix it. This device can reduce external electromagnetic interference to the inductor and extend the service life of the protective magnetic layer 5.
