POWER SUPPLY DEVICE

PROBLEM TO BE SOLVED: To provide a power supply device in which radiation of a heating component such as a winding component and a switching element is suitably performed and each of a plurality of kinds of heating components is fixed to a substrate or a housing by a proper pressing force and which is capable of being assembled by a simple method.SOLUTION: Disclosed is a power supply device having a component fixing metal fitting 10 by which a heating component mounted on a substrate 2 is fixed to the substrate side by being pressed to the substrate side. The component fixing metal fitting includes: a first plane part 11 which is substantially parallel to the substrate; and a second plane part 13 which is formed with a step from this first plane part and substantially parallel to the substrate. In the first plane part and the second plane part, a pressing part is provided which presses the heating component directly or indirectly to the substrate side.SELECTED DRAWING: Figure 1 【課題】巻線部品やスイッチング素子等の発熱部品の放熱が好適に行われ、かつ複数種類の発熱部品がそれぞれの好適な押圧力により基板または筐体に固定されると共に、簡易な方法により組み立てが可能な電源装置を提供すること。【解決手段】基板２に搭載された発熱部品を基板側に押圧して固定する部品固定金具１０を備えた電源装置であって、部品固定金具は、基板と略平行である第１平面部１１と、この第１平面部から段差を持って形成され基板と略平行である第２平面部１３とを有し、第１平面部および第２平面部には、発熱部品を基板側に直接または間接的に押圧する押圧部が設けられている。【選択図】図１
