Embodiment Construction

[0050] The patch type power inductor of the present invention includes a magnetizer and an enameled wire coil, wherein the coil includes a main body and an extension part, the magnetizer and the coil are integrally formed, and the material constituting the magnetizer is tightly filled in the The inside of the coil main body is tightly wrapped on the outside of the coil main body; the extension of the coil protrudes out of the magnetic conductor to form the electrodes of the inductor, and the electrodes are welded with the magnetic conductor. Electrode end piece. Preferably, the extension part is a flat structure, protrudes from opposite side surfaces of the magnetic conductor respectively, and is respectively bent to be close to the bottom surface of the magnetic conductor. The detailed manufacturing process and product structure are detailed below.

[0051] 1. Preparation of magnetic conductor powder

[0052] Among the present invention, the magnetizer mainly consists of two ...

Abstract

The invention relates to an SMD power inductor, which comprises a magnetizer and an enamelled wire coil, wherein the coil comprises a main body and an extension part; the magnetizer and the coil are integrated into an integral structure; a material for preparing the magnetizer is tightly filled in the main body and is tightly coated outside the main body; the extension part extends out of the magnetizer to form an electrode of the inductor; and an electrode tip attached to the magnetizer is welded on the electrode. The invention also relates to a method for manufacturing the SMD power inductor, which comprises the following steps: preparing the coil and powder for preparing the magnetizer; diecasting the coil and the powder; and welding the electrode tip on the electrode of the coil. The SMD power inductor and the manufacturing method thereof have the advantages of good electric property of the inductor, high production efficiency and good consistency of product performance.

Description

technical field [0001] The present invention relates to wire-wound inductors, more specifically, to a chip-type power inductor and a manufacturing method thereof. Background technique [0002] The main components of the existing SMD power inductors are coils and magnetic conductors, where the magnetic conductors can be magnetic cores, iron cores or copper cores. Such as figure 1 and figure 2 As shown, in the existing SMD power inductor products, the shape of the magnetic conductor 102 is usually cylindrical, I-shaped (such as figure 2 ), ring, etc.; the enameled wire 103 is wound on the outside of the magnetic conductor 102 to form a coil, and then the magnetic ring 104 is bonded to the magnetic conductor 102 with glue 101, and then the electrode 105 and the electrode end piece 106 are welded on the magnetic conductor 102 , and finally form a cylindrical SMD power inductor and an I-shaped SMD power inductor (such as figure 1 and figure 2 ), and an annular chip power ...
