Inductor Skeleton

Abstract

An inductor skeleton includes a chip set and an insulating shell, the insulating shell wraps the chip set, the chip set is composed of stacked silicon steel sheets, each of the silicon steel sheets includes a winding part and a The diode part connected to both ends of the winding part, the diode part and the winding part are distributed in an "I" shape, the pole part includes a straight section and an arc section, wherein the straight section is arranged on the inner side , the arc segment is arranged on the outside, the straight segment is arranged in a rectangle, the arc segment is arcuate, the outer side of the arc segment is arranged in a convex circular arc, and the middle part of the outer side of the arc segment There is an inner groove extending inwardly. In the present invention, poles are arranged at both ends of the winding portion, the volume of the silicon steel sheet is increased, the magnetic permeability is increased, the inductance of the inductor can reach the required value by using less copper wires, and the amount of copper wires is reduced. And reduce the DC impedance of the copper wire, reduce the heat generation, prolong the service life of the product, and make the inductance Q value higher.

Description

technical field [0001] The invention relates to an assembly of electronic components, in particular to an inductance frame for improving the Q value of inductance. Background technique [0002] Inductors are components that can convert electrical energy into magnetic energy and store it. Inductors are similar in construction to transformers, but with only one winding. Inductors have a certain inductance, which only resists changes in current. If the inductor is in a state where no current is flowing, it will try to block the current from flowing through it when the circuit is on; if the inductor is in a state where current is passing, it will try to maintain the current when the circuit is off. Inductors are also called chokes, reactors, and dynamic reactors. [0003] The structure design of the existing inductor magnetic core is unreasonable, and there is a disadvantage that the inductance cannot meet the requirements. Therefore, when designing the inductance, it is nece...

Problems solved by technology

[0003] The structure design of the existing inductor magnetic core is unreasonable, and there is a disadvantage that the inductance cannot meet the requirements. Therefore, when designing the inductance, it is necessary to make up for it by increasing the number of turns of the coil. However, increasing the number of turns of the coil will bring about many problems , On the one hand, increasing the number of turns of the coil will waste a lot of copper wires and increase the volume of the inductor, which is inconsistent with the mainstream design of electronic products, and also increases the manufacturing cost of the inductor. On the other hand, increasing the number of turns of the coil It will further increase the resistance value of the copper number, and the heat generated by the inductor will be too large, which will affect the normal operation of electronic products, and reduce the Q value of the inductor, which will affect the performance of the inductor
