Inductance element and shaping method thereof

Abstract

The invention provides an inductance element and a shaping method thereof. The method comprises the following steps of: respectively shaping flat coils at the surfaces of at least two or more than two coil layers; respectively arranging switching conductors and electrode pin positions at the external surfaces of two ends of the flat coils of the top coil layer, wherein each switching conductor is connected to the internal surface of the other side in a penetrating way; respectively shaping switching connecting points, and electrically connecting to the switching conductors at two ends of the flat coils of more than one coil layer below the top layer, so that the flat coils of each coil layer can mutually conduct with one another; and assembling, overlapping and combining at least two or more than two layers of coil layers, and respectively forming central through holes at the internal side of each flat coil, so that a metal inner core can be filled. An electromagnetic induction effect can be generated in match with the peripheral flat coils, namely shaping the inductance element. The inductance element has the characteristic of flatness and small size, and light, thin, short and small design requirements of electronic parts can be satisfied.

technical field [0001] The present invention designs a structure and molding method of an inductance element, especially a molding method of an inductance element with a flat shape and a small volume. The electromagnetic induction effect is generated through the electrical connection and conduction of the flat coil between the laminated coil layers. Formed into inductive components for circuit board use. Background technique [0002] Among many electronic components, the inductance element is of auxiliary nature, and its main function is to hinder the change of the current to maintain the stability of the electronic product. The structure of the inductance element can be designed according to the different application circuits, and different structures are designed, and at present Commonly used inductive components are roughly divided into two types of application modes. One is for signal purposes, such as: energy storage and suppression of instantaneous current, etc., and t...

AI Technical Summary

Problems solved by technology

[0004] And the inductance element can be divided into wire-wound type and multi-layer type according to the structure. Among them, the wire-wound type is the most commonly used technology, because it has the advantages of small loss, large allowable current, simplicity, and low cost. However, its structure is restricted. However, according to electromagnetic theory, coils are used to wind iron cores to form inductance components. Most traditional inductance components are produced by winding wires. The thickness of the coils can be used to control the degree of current resistance. The number of windings is used to adjust the inductance value. The design has a large flexible space, but the biggest disadvantage is that the size is not easy to shrink.

[0005] Therefore, how to solve the problems and defects of the existing inductive elements such as large loss of electromagnetic rate, difficulty in reducing volume, and cost increase due to the use of coil materials is what the inventor and related manufacturers engaged in this industry are eager to study. , the direction of improvement
