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.
Abstract:
An electronic device connected to a wire is provided, including a printed circuit board having a hole, a hollow tube, a plurality of blades separated from each other, and a solder, wherein the wire in inserted into the hollow tube and electrically connected to the printed circuit board. The hollow tube is extended through the hole. The solder is connected to the blades and the printed circuit board. The blades are connected to the hollow tube, and a reflex angle is formed between the inner wall of the hollow tube and each of the blades.
Abstract:
A metal housing is provided. The metal housing includes a bottom plate, a first side plate, a second side plate, a third side plate, a fourth side plate, and a ground portion. The second side plate is parallel to the first plate. The fourth side plate is parallel to the third side plate. The first side plate, the second side plate, the third side plate, and the fourth side plate are integrally formed on the bottom plate. The ground portion is formed on an inner surface of one of the side plates. The ground portion includes a restriction structure and an opening. The restriction structure is integrally formed on the inner surface. The restriction structure is adapted to hold a ground line.
