Integrating type magnetic component

Abstract

The invention relates to an integrating type magnetic component arranged on a system circuit board. The integrating type magnetic component comprises a first magnetic component and a second magnetic component, wherein the first magnetic component comprises a primary winding, a secondary winding, a magnetic core group and a containing groove; the primary winding is provided with at least one end part; the secondary winding is arranged corresponding to the primary winding; the magnetic core group is sleeved on the primary winding and the secondary winding, and part of the magnetic core group is covered by the primary winding and the secondary winding; and the second magnetic component is provided with a center hole and a plurality of guide connection ends, contained in the containing groove of the first magnetic component and electrically connected with the system circuit board by utilizing the guide connection ends, and the end part of the primary winding of the first magnetic component passes through the center hole of the second magnetic component and is electrically connected with the system circuit board.

Description

technical field [0001] The invention relates to an integrated magnetic assembly, in particular to an integrated magnetic assembly integrated with a current sensor. 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 the circuit of the server as an example, it must detect the current of the transformer through a current sensor, such as a current transformer. see figure 1 , which is a schematic diagram of the existing transformer and current sensor installed on the system circuit board. As shown in the figure, the existing transformer 10 and current sensor 11 are respectively installed on the system circuit board 1, and the primary winding outlet of the transformer 10 The...

Problems solved by technology

[0004] However, the independent configuration of the transformer 10 and the current sensor 11 will occupy a large amount of space on the system circuit board 1, which will cause some unusable distorted space on the system circuit board 1, so it cannot meet the development trend of miniaturization of electronic equipment.

In addition, because the transformer 10 and the wire 112 of the current sensor 11 must be electrically connected through the layout circuit of the system circuit board 1, not only the assembly is inconvenient, but also the loss of electric energy may be caused.
