Abstract

An electronic device includes a casing, a circuit board, an electronic component and a fixing member. The casing includes a fixing pillar and at least one rib. The rib is connected to a periphery of the fixing pillar. The circuit board includes a through hole. The fixing pillar is disposed in the through hole. The circuit board abuts against a second top surface of the rib. A thickness of the circuit board is smaller than a height between a first top surface of the fixing pillar and the second top surface of the rib. The electronic component includes a first metal member. A first ground end of the first metal member is disposed on the first top surface of the fixing pillar. A gap exists between the first ground end and the circuit board. The fixing member fixes the first ground end to the fixing pillar.

Description

technical field [0001] The invention relates to an electronic device, in particular to an electronic device capable of effectively grounding electronic components. Background technique [0002] Currently, the circuit boards of many electronic devices are provided with power sockets for connecting power lines. Generally speaking, the power socket has a ground wire, and the ground wire is fixed in a ground screw hole of an iron piece to form a ground loop. In order to prevent the grounding wire from contacting the circuit board, the circuit board must be provided with two fixing holes, one of which is used for safely grounding the power plug, and the other fixing hole is used for fixing the circuit board. Therefore, the grounding method of the prior art is inefficient and increases the manufacturing cost. Contents of the invention [0003] The object of the present invention is to provide an electronic device capable of effectively grounding electronic components to solve ...
