Surface adhesion type magnetic element

Abstract

The invention discloses a surface adhered magnetic member, at least comprising: a magnetic conduction module provided with a first magnetic conduction unit and a second magnetic conduction unit, which are combined to form a receiving space, wherein, the second magnetic conduction unit is provided with a first surface and a second surface, and the second magnetic conduction unit is connected with the first magnetic conduction unit via the first surface; a coil which is partly arranged in the receiving space of the magnetic conduction module, and which includes at least two pins extending on the second surface of the second magnetic conduction unit; and an extending portion which is integrated in at least a part of the second surface of the second magnetic conduction unit. The invention solves the defect that the surface adhered magnetic member can not disposed on a circuit board stably and reposefully, and improves the ability of positioning the surface adhered magnetic member the circuit board.

Description

Surface Mount Magnetics technical field The invention relates to a magnetic element, in particular to a surface-adhesive magnetic element. Background technique Magnetic components, such as inductors or transformers, are indispensable basic components for the operation of various electronic devices, such as power supply devices or power conversion devices. With the development of power supply devices or power conversion devices towards miniaturization and high power, the magnetic components also need to be improved in the direction of small size and flat structure. In addition, in order to facilitate the assembly of magnetic components on circuit boards, various surface mount magnetic component structures that can utilize surface mount technology (Surface Mount Technology, SMT) to assemble magnetic components on circuit boards have been developed. Please refer to FIG. 1( a ), which is a schematic diagram showing the structure of a traditional surface mount inductor compone...

AI Technical Summary

Problems solved by technology

The main purpose of the present invention is to provide a surface-mounted magnetic component, which uses the extension formed by the bottom surface of the magnetic group of the surface-mounted magnetic component to assist the contact between the pins of the surface-mounted magnetic component and the relative contact area of ​​the circuit board. Fixing and connecting to prevent surface mount magnetic components from detaching from the circuit board, solving the shortcomings of surface mount magnetic components that cannot be flatly and firmly arranged on the circuit board, and improving the ability of surface mount magnetic components to be positioned on the circuit board
