1. An electronic device comprising:
a circuit board comprising a plate body, at least one perforation and at least one ground wire, wherein the at least one perforation penetrates through the plate body, wherein two opposite ends of the at least one ground wire are electrically coupled with the plate body, and are respectively disposed adjacent to two sides of the at least one perforation, wherein the at least one ground wire is disposed on and crosses over the at least one perforation, and the at least one perforation is divided into two parts by the at least one ground wire; and
a casing comprising a bottom plate, at least one clamping structure and an accommodating space, wherein a part of the bottom plate is bent from the remaining part of the bottom plate toward the accommodating space to form the at least one clamping structure, wherein the at least one clamping structure and the bottom plate are integrally formed into one piece structure, wherein the at least one clamping structure comprises a first clamping part and a second clamping part, which are disposed apart from each other,
wherein the circuit board is disposed in the accommodating space of the casing, the at least one clamping structure of the casing penetrates through the plate body through the at least one perforation, so that the circuit board is positioned on the casing, and the at least one ground wire is clamped by the first clamping part and the second clamping part of the at least one clamping structure, so that the circuit board is grounded with the casing.
