Integrated magnetic module and conductive structure thereof

Abstract

The invention relates to an integrated magnetic module and a conductive structure thereof. The integrated magnetic module arranged on a system circuit board comprises a winding base which comprises a body for a primary winding to wind, a penetration channel penetrating the body, a magnetic core group and a conductive structure. The conductive structure comprises a plurality of corresponding conductive units and first magnetic modules, wherein each conductive unit is provided with a hollow hole, a containing hole and a pin, and each first magnetic module is penetrated in the containing hole ofeach conductive unit through a junction so as to be electrically connected with the conductive unit. The conductive units are separated from each other by the body of the winding base, while the hollow hole corresponds to the penetration channel to hold the magnetic core group for combing the winding base, the magnetic core group and the conductive units into a second magnetic module. The first magnetic module and the second magnetic module are integrated by the conductive structure and arranged on the system circuit board through the pin of each conductive unit. The integrated magnetic modulehas simple assembly, and avoids damaging the insulation materials of the conductive wires of the magnetic module under high-temperature welding.

Description

technical field [0001] The invention relates to a magnetic component and its conductive structure, in particular to an integrated magnetic component and its conductive structure. Background technique [0002] Generally speaking, there are many magnetic components in electrical equipment, among which transformer is a common magnetic component, which uses the principle of electric energy and magnetic energy conversion induction to adjust the voltage to make the voltage reach the applicable range of electrical equipment. [0003] Taking a flyback transformer (flyback) as an example, when it is installed on a system circuit board of an electrical device, it generally needs to be electrically connected with another common magnetic component, such as an inductor (choke coil).

AI Technical Summary

Problems solved by technology

Please refer to FIG. 1 , which is a schematic diagram of an existing transformer and inductor arranged on a system circuit board. As shown in the figure, the existing transformer 10 and inductor 11 are respectively arranged on the system circuit board 1 with an adhesive 12 , and They are electrically connected to each other through the layout lines (trace, not shown) of the system circuit board 1. However, the independent configuration of the transformer 10 and the inductor 11 will occupy a large amount of space on the system circuit board 1, causing some difficulties in the system circuit board 1. The space used is distorted, so it cannot meet the development trend of increasing the power and reducing the volume of electronic equipment

In addition, since the transformer 10 and the inductor 11 must be electrically connected through the layout lines of the system circuit board 1, this will also cause current impedance and loss

Moreover, the transformer 10 and the inductor 11 need to be welded to the preset position of the system circuit board 1 by the solder 13 after the winding is completed, and in order to ensure the depth of the tin, the welding place may be in contact with the winding of the transformer 10 and the inductor 11. The wires are relatively close, and the insulation material outside the wires of the transformer 10 or inductor 11 is burnt due to high temperature, which affects its safety and performance.
