AI Technical Summary
Existing plug-in inductors suffer from problems such as inaccurate manual assembly, low glue fixing efficiency, and high risk of detachment during production and processing. After thermoforming, the inductor structure is not easy to demold and has limited heat dissipation area. Insufficient coil gap leads to poor contact and extrusion.
The inductor is a plug-in type with one-piece molding. The magnet and flat coil are designed with an elliptical structure. The two ends of the coil are pins. The magnet has heat dissipation grooves on both sides. There is a gap between the coils. The magnet has an inverted trapezoidal structure to facilitate demolding and powder filling. The coil is made of enameled wire.
It improves the heat dissipation area and demolding efficiency of the inductor, avoids coil contact and compression, ensures full powder filling, and solves the assembly error and demolding problems in traditional processing.
