摘要： A supporting frame has a frame body and at least one connecting post. The frame body has a connecting face and an edge. The at least one connecting post is formed on and extends from the connecting face at the edge. Each connecting post is hollow and conical and has an enlarged end, a reduced end and at least one slit. The enlarged end has a diameter and is formed on the connecting face of the frame body. The reduced end has a diameter smaller than that of the enlarged end and is away from the connecting face of the frame body. The at least one slit is longitudinally formed in the connecting post. Accordingly, the supporting frame can be easily and precisely combined with a circuit board.

摘要： A transient current suppression device, which is applied to a fan, includes a filtering circuit, a delayed turn-on circuit and a forcibly electrical discharging circuit. The filtering circuit outputs a first voltage signal and a first current signal according to a first power signal. The delayed turn-on circuit is electrically connected with the filtering circuit. The delayed turn-on circuit provides a first discharging path for the first current signal according to a second power signal after a delayed time and outputs a second current signal. The forcibly electrical discharging circuit is electrically connected with the delayed turn-on circuit and the filtering circuit. The forcibly electrical discharging circuit provides a second discharging path for the second current signal according to the first voltage signal. Hence, the transient current suppression device can suppress the transient current effectively and rapidly.
