Description

A Combined Shielded Inductor

technical field

The utility model relates to a shielding inductor, in particular to a combined shielding inductor.

Background technique

Inductor is a common electronic component in the circuit. It mainly plays the role of filtering, oscillating, delaying, trapping, etc. in the circuit, as well as filtering signals, filtering noise, stabilizing current and suppressing electromagnetic interference. It is relatively extensive. In order to facilitate the installation of inductors, many inductors are now set up as vertical inductors that can be plugged and welded. The magnetic core is usually a dumbbell structure, with wires wound in the middle and pins at the bottom. Finally, the magnetic core is placed in the shielding shell and encapsulated by colloid. The inductor with this type of structure has poor winding effect, low structural stability, high defect rate, and cumbersome and time-consuming assembly and processing.
