<p>PURPOSE:To effectively radiate the heat of a magnetic core, by exposing a metallic plate having thermal conductivity against the magnetic core, to the outside of a case, and also projecting this metallic plate to the outside from the case through a fitting plate part. CONSTITUTION:A magnetic core 1 consisting of ferrite, a coil 2 wound to the magnetic core 1, and a thermal conductive member 3 constituted of a material which is a nonmagnetic material such as copper and aluminum, and has good thermal conductivity are made to tightly adhere to the magnetic core through its center part, and also both sides are extended and become a fitting plate part 31. The fitting plate part 31 has a fitting hole 5. In a case 4 made of a resin such as polyacetal, etc., the magnetic core 1 is stored. Also, the lower surface of this case 4 is opened, and the metallic plate 3 is exposed. A tape guide 6 consists of the same material as the metallic plate 3, and desirably, it is formed as one body with the metallic plate 3 or has a tightly stuck construction so as to have thermal conductivity with the metallic plate 3, and positions a magnetic tape (not shown in fiture).</p> |
