Description

Technical Field

[0001] The utility model discloses an inductor, in particular to an integrally formed single multi-in-one inductor, belonging to the technical field of electronic components. Background Art

[0002] An inductor is a fundamental component in electrical circuits, used to store and release electromagnetic energy. Its primary characteristic is its ability to generate an induced electromotive force (EMF) when current changes, thereby hindering that change. The operating principle of an inductor is based on the law of electromagnetic induction. When current flows through an inductor coil, the coil generates a magnetic field. When the current changes, the magnetic field also changes. According to Faraday's law of electromagnetic induction, this magnetic field change generates an induced electromotive force within the inductor. This electromotive force hinders the change in current, forming the primary characteristic of the inductor.

[0003] Most current inductors are single-piece designs, meaning they contain only one inductor. If a circuit requires multiple inductors, multiple inductors must be assembled. This not only takes up more circuit board area, making the entire product larger, but also creates certain difficulties in PCB design and the soldering of electronic components.

[0011] The electrode is in an "L" shape, wherein part of it is located on the side of the substrate and part of it is located on the bottom of the substrate.

[0023] This embodiment is a preferred implementation of the present utility model. Other embodiments whose principles and basic structures are the same or similar to those of this embodiment are within the protection scope of the present utility model.

[0024] The present invention mainly protects an integrally formed single multi-inductor, which mainly includes a base, two or more coils 5 and electrodes 3. The two or more coils 5 are respectively fixedly arranged in the base, and the electrodes 3 are respectively connected to the two ends of the coils 5, and the electrodes 3 are used as welding pins.

[0025] In this embodiment, the coil 5 and the electrode 3 are integrally provided, and are artificially defined as the coil 5 and the electrode 3. The electrode 3 is formed by partially extending the coil 5. In specific implementation, the coil 5 and the electrode 3 can also be separately provided and then fixedly connected together by welding or other processes.

[0026] In this embodiment, the coils 5 are arranged in parallel within the base.

[0027] In this embodiment, the coil 5 is preferably formed by winding a flat copper wire. In specific implementation, it can also be made of round copper wire or copper sheet, wherein the coil 5 is partially in the shape of a "I", a "concave", a semicircular, a spiral or a spiral. The surface of the coil 5 may be insulated (forming an enameled wire) or not. The end of the coil 5 extends to form the electrode 3. In this embodiment, the electrode 3 is in an "L" shape, wherein part of it is located on the side of the substrate and part is located at the bottom of the substrate. In this embodiment, the electrode 3 is subjected to an electrode surface treatment, and the electrode surface treatment can be performed by electroplating or tin immersion. In this embodiment, a groove 4 is provided on the substrate at a position corresponding to the position of the electrode 3. The electrode 3 is located in the groove 4, which can make it more secure and not easy to fall off.

[0028] In this embodiment, the substrate is formed by compression molding using soft magnetic composite material powder. The substrate is artificially divided into an upper substrate 1 and a lower substrate 2. The upper substrate 1 and the lower substrate 2 are fixed together to form the entire substrate. Dividing the upper substrate 1 and the lower substrate 2 facilitates processing. During processing, the upper substrate 1 is first machined, and then the coil 5 and the electrode 3 are placed on the upper substrate 1. The lower substrate 2 is then formed by compression molding, and the coil 5 and the electrode 3 are fixed to the substrate. In this embodiment, one or more pillars 6 are fixedly installed on the upper substrate 1 at positions that do not interfere with the coil 5. In this embodiment, two pillars are provided. However, a specific number can be provided according to actual needs during implementation.

[0029] The manufacturing method of the integrated single multi-inductor in the present invention mainly includes the following steps:

[0030] Step S1: using two or more copper sheets or copper wire windings as coils to form a single multi-inductor component through pressing, and the ends of the copper sheets or copper wires are subjected to surface metallization treatment to serve as inductor electrodes;

[0031] Step S2: a copper sheet or coil of a certain shape is implanted into a magnetic core formed of a soft magnetic composite material and fixed;

[0032] Step S3: After the assembly is placed in a molding mold, soft magnetic composite material powder is added and compression molded. During the compression molding, the temperature is generally set between 120° C. and 180° C. to ensure that the material can be evenly distributed and solidified during the molding process. The compression molding pressure is generally set between 20 MPa and 50 MPa to ensure that the material is completely filled in the mold and formed into the desired shape and density.

[0033] Step S4: The molded product undergoes heat treatment and terminal electrode treatment to form a single multi-inductor component. In this embodiment, the heat treatment temperature is between 200° C. and 400° C., which is mainly used to eliminate stress during the manufacturing process and improve the uniformity and performance of the material.
