Abstract: An electronic device is provided and includes a circuit board and a casing. The circuit board includes a plate body, a perforation and a ground wire. The perforation penetrates through the plate body, the ground wire is electrically coupled with the plate body and crosses over the perforation. The casing includes a bottom plate and a clamping structure. The clamping structure is disposed on the bottom plate and includes a first clamping part and a second clamping part. The circuit board is disposed in the casing, and the clamping structure penetrates through the plate body through the perforation, so that the circuit board is positioned on the casing, and the ground wire is clamped by the first clamping part and the second clamping part of the clamping structure. Consequently, the circuit board is grounded with the casing.

Abstract: A hanging grounded structure is disclosed and includes a housing, a recessed portion and a hanging groove. The housing includes an opening facing a first direction and a lateral wall extended along a second direction. The lateral wall has a top edge located at a periphery of the opening. The recessed portion is recessed inwardly on the lateral wall. The hanging groove is disposed on the lateral wall and located in the recessed portion. A grounded wire is hung on the housing through the hanging groove. The hanging groove includes a starting point located at the top edge and an ending point. A curved path is formed from the starting point to the ending point. The grounded wire is hung from an interior of the housing. An end of the grounded wire is disposed in the recessed portion through the hanging groove.

Abstract: A circuit board assembly includes a printed circuit board, at least one wire, at least one wire fixing device, and a plurality of electronic components. A wire fixing method includes following steps. Firstly, the wire fixing device is inserted into a conductive hole of the printed circuit board. Then, the wire fixing device is fixed on the printed circuit board via a soldering material. Then, a conducting terminal of the wire is introduced into an accommodation space of the wire fixing device through the first opening of the wire fixing device. Then, at least one concave structure is formed in an external surface of a first conducting part of the wire fixing device by a jig. Consequently, the conducting terminal of the wire is fixed on the wire fixing device, and the wire is electrically connected with the printed circuit board through the wire fixing device.
