Publication number: 20150109749Abstract: 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.Type: ApplicationFiled: April 2, 2014Publication date: April 23, 2015Applicant: DELTA ELECTRONICS, INC.Inventors: Ching-Ho Chou, Do Chen, Shang-Yu Li, Chun-Jen Chung
