Description

Technical Field

[0001] The invention relates to an electronic device, in particular to an electronic device with low magnetic interference and a magnetic shielding member thereof. Background Art

[0002] With the advancement of technology, miniaturization of electronic devices has become one of the current trends. Common electronic devices on the market, such as power adapters, usually contain multiple electronic components (such as transformers, inductors) and assembly parts (such as housings). In order to meet the needs of miniaturization, the configuration between electronic components and assembly parts must be designed to be more compact. However, an overly compact configuration will result in excessive magnetic interference between multiple electronic components. In addition, when the distance between electronic components and assembly parts is too close, the magnetic interference of the electronic components will be reflected by the assembly parts, so that the electronic components will still be affected by the magnetic interference.

[0003] To solve the above problems, in some prior arts, the electronic device further includes a copper plate. The copper plate is vertically arranged between two electronic components and grounded, thereby reducing the magnetic interference between the two electronic components. However, the vertical copper plate is large in size and cannot meet the requirements of miniaturization, and also increases the difficulty of the electronic device manufacturing process. In addition, the copper plate has a high cost and a low degree of freedom in use.

[0004] In addition, in some other prior arts, the housing (i.e., assembly part) of the electronic device further includes an opening. The position of the opening is set corresponding to the electronic component. The magnetic interference reflected by the housing is reduced by setting the opening. However, since the housing is provided with the opening, the heat dissipation area of ​​the housing is reduced, and the heat dissipation efficiency of the electronic device is reduced. In addition, setting the opening in the housing requires additional manufacturing costs and the manufacturing process is complicated.
