However, with such a housing, the production process of the product is complicated, and the operation is delicate. The head of the lead of the magnetic ring needs high-temperature tin immersion to remove the insulating layer on the surface of the copper wire, the requirement of the removal position is kept consistent, and the tin immersion of a plurality of leads needs to avoid mutual tin connection. The length from a depainting point of a lead of the magnetic ring to a Pin foot at the bottom needs to be reasonably controlled, the lead is difficult to arrange and the DCR is increased due to overlong lead accumulation, and the magnetic ring is pulled up and suspended due to overlong lead accumulation, so that the disconnection is easily caused. And (3) clamping the lead wire by adopting a tool with a smooth surface for winding, wherein the lead wire wound on the Pin needle needs to be tightly bound, otherwise the lead wire is easy to scatter.
