Description
Technical Field
The utility model relates to an inductor specifically is a big inductance power inductor.
Background
An inductor is a component that can convert electrical energy into magnetic energy for storage. The inductor is similar in structure to a transformer, but has only one winding. The inductor has a certain inductance which only impedes the change of the current. If the inductor is in a state where no current is passing, it will try to block the current from flowing through it when the circuit is on; if the inductor is in a current passing state, the inductor will try to keep the current unchanged when the circuit is opened.
The existing iron-silicon-aluminum magnetic ring inductor forms an inductor through a magnetic ring and a winding on the magnetic ring, and the inductor formed by the method needs to be used in occasions with larger inductance requirements, occupies a large space and increases the use cost.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a big inductance power inductor to solve above-mentioned technical problem.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a high inductance power inductor, includes the PCB circuit board, be fixed with sendust magnetic ring group on the PCB circuit board, sendust magnetic ring group symmetry set up in the both sides of PCB circuit board top terminal surface, every group sendust magnetic ring group includes a sendust magnetic ring, and a plurality of sendust magnetic rings in a set of sendust magnetic ring group laminate each other, and coaxial setting, and the winding of two sets of sendust magnetic ring group that the symmetry set up is provided with the copper line, the copper line is in proper order, the inboard multiturn of two sets of sendust magnetic ring group of circulation winding.
Preferably, the outer rings of the two groups of sendust magnetic ring groups are wound and stuck with adhesive tapes.
Compared with the prior art, the beneficial effects of the utility model are that:
through the two groups of sendust magnetic ring sets symmetrically arranged on the PCB, a plurality of sendust magnetic rings on each group of sendust magnetic ring set are arranged in a pairwise overlapping manner, and a plurality of circles of copper wires are sequentially and circularly wound on the two groups of sendust magnetic ring sets, so that the inductance of the inductor supported by the method is doubled, the larger inductance can be achieved, and the finished product and the volume can be effectively reduced by the method of winding the copper wires in the middle.
