Description

electronic device

technical field

The present invention relates to electronic devices, in particular, the present invention relates to a portable electronic device capable of preventing leakage current from crossing and having safety protection.

Background technique

A traditional notebook computer has a keyboard, an upper case, a lower case and a circuit board, wherein the upper case and the lower case are made of conductive materials, and the keyboard is disposed on the upper case. The edge of the upper shell is connected to the edge of the lower shell, and the upper shell and the lower shell form an accommodating space, so that the circuit board is arranged in the accommodating space. In addition, the circuit board is locked and attached to the studs of the upper casing by screws, wherein the screws and studs are conductive materials.

In actual situations, the electric current of the circuit board unexpectedly enters the studs through the screws, and then flows to the upper casing. This unexpected current is leakage current. Leakage current is due to poor design of electronic products, causing the system to generate current when it is in standby and not in operation. Leakage current consumes unnecessary power and causes additional power loss. In addition, when the user touches the upper case, there will be a numb electric shock feeling on the hand. Furthermore, the circuit board is connected to the lower case through the conductive member, so that the leakage current flows from the circuit board to the lower case, and then flows to the upper case, which also causes tingling sensation on the user's hands. Once the leakage current flows to the upper casing or the lower casing, the power consumption of the product will be caused, thereby affecting the operating efficiency of the product.

Although the shell made of insulating material can block the leakage current to solve this problem. However, under the consideration of aesthetic factors, most of the current casings are made of metal materials to present the metal texture of the product. Metal is a conductive material, and the above problems still exist. Another industry has applied insulating varnish to the surface of the shell that is in contact with the hand, but it has lost the original intention of the metal texture, and cannot achieve both aesthetics and user experience. In addition, when the user uses the product for a period of time, the insulating varnish on the contact surface of the shell is easy to fall off, which cannot completely improve the above shortcomings.

Contents of the invention

The electronic component is disposed in the first accommodating space and has at least one through hole corresponding to the fixing hole. The fixing pieces correspondingly pass through the through holes and are combined with the fixing holes to fix the electronic components.

In an embodiment of the present invention, at least part of the second casing is made of conductive material, and the electronic component includes the conductive component. When the conductive part contacts the second casing, current flows from the electronic component to the conductive part, so that the current contacts the inner surface of the second casing.

In the embodiment of the present invention, the inner surface of the second casing has an insulating layer, and the insulating layer is used to insulate the first casing. The inner surface of the first casing has an oxide layer for insulation from the second casing. The electronic device further includes at least one adhesive layer, and the adhesive layer is used for adhering the bonding element to be fixed on the first casing.
