Abstract

The invention discloses a patch type inductive element and a manufacturing method thereof. The inductive element comprises a magnetic core body, a coil and a magnetic core top cover, wherein the magnetic core body is provided with a bottom and a winding part protruding from the bottom; the coil is wound on the winding part of the magnetic core body; the magnetic core top cover is provided with a winding part containing cavity; the winding part of the magnetic core body is inserted into the winding part containing cavity of the magnetic core top cover; the magnetic core body is adhered with themagnetic core top cover through an adhesion material; a first electrode board and a second electrode board are respectively arranged at two ends of the bottom of the magnetic core body; wire handingslots are formed in the side surfaces of the electrode boards; and two ends of the coil are welded on the electrodes and are led out and led in through the wire hanging slots in the side surfaces of the electrode boards. The patch type inductive element is capable of remarkably improving the automatic level of production of the patch type inductive element and remarkably improving the product production efficiency and yield, thereby realizing automation, keeping relatively product characteristics and having strong product applicability.

Description

technical field [0001] The invention relates to an inductive element, in particular to a patch type inductive element and a manufacturing method thereof. Background technique [0002] The inductive element has the function of passing direct current and delaying alternating current, and its structure is relatively diverse. The inductive element can be formed by forming a loop with conductive materials such as coils. The coil of the inductive element has one winding or multiple windings. In a broad sense, structures with multiple windings such as common mode chokes and low-power isolation transformers can also be called inductive components. [0003] There are many kinds of inductive components, most of which are made of ferrite cores surrounded by outer coils, while some protective inductive components have the coils completely inside the ferrite. A magnetic core material with a higher permeability than air can confine the magnetic field more tightly around the inductive el...
