Problems solved by technology

In this way, if the leakage current Ic flows back to the motherboard 120 , since the motherboard 120 and the metal casing 110 are electrically insulated by the insulating material 140 , the leakage current Ic cannot flow to the metal casing 110
However, leakage may occur at the non-planar position between the motherboard 120 and the metal casing 110, or induction electrification may occur when the distance between the motherboard and the metal casing is too short, thereby affecting the electrical performance.
[0006] In addition, in order to prevent the user from feeling an electric shock, insulating material can also be coated on the entire metal casing 110, but this will increase the production cost and reduce the overall texture of the metal casing 110.

Embodiment Construction

[0022] Generally speaking, when metal is used as the casing of an electronic device (such as a notebook computer), it is easily affected by external influences or the leakage current inside the electronic device flows back to the casing, resulting in excessive accumulation on the surface of the casing. static charge. In this way, when the user touches the housing while using the electronic device, the excess static charge accumulated on the housing will flow to the user for discharge, causing the user to feel an electric shock. However, the electrostatic charge distributed on the surface of the casing is usually an AC signal, while the leakage current inside the electronic device is usually a DC signal. Therefore, for this characteristic, this embodiment can use electronic components with high-frequency conductivity, wherein The AC signal can pass through the electronic component with high-frequency conductivity, while the DC signal will be absorbed or filtered by the electron...

Abstract

An electronic device at least comprises: a chassis, a circuit board and an electronic component possessing high frequency conductivity. The circuit board possesses a first part and a second part. The first part is electrically connected with the chassis. The second part is electrically connected with a grounding terminal. The electronic component possessing the high frequency conductivity forms bridge connection between the first part and the second part of the circuit board. There is no other electrical connection between the first part and the second part except the electrical connection established by the electronic component possessing the high frequency conductivity. By using the electronic device of the invention, a user can not generate a feeling of electric shock when touching the chassis.

Description

technical field [0001] The invention relates to an electronic device, and in particular to an electronic device capable of preventing leakage current from flowing backward to the housing. Background technique [0002] Figure 1A A schematic diagram of a conventional electronic device. Please refer to Figure 1A , the electronic device 100 a includes a metal casing 110 , a motherboard 120 and a power cord 130 . The motherboard 120 is located in the metal casing 110 and is electrically connected to the metal casing 110 . The power cable 130 is connected to the motherboard 120 for transmitting power to the motherboard 120 . [0003] Generally speaking, the power line 130 usually has a ground terminal GN, and the ground terminal of the mainboard 120 is electrically connected to the ground terminal GN of the power line 130. In this way, when the mainboard 120 generates a leakage current Ic, the leakage current Ic can flow to the ground through the ground terminal GN of the pow...
