Two clamping slots are provided on the top and bottom of the second winding slot group, respectively. A shield in the shape of an “n” is provided on one side of the second bobbin. The shield includes bent flanges along two edges thereof. The two flanges are inserted into the two clamping slots, respectively to fasten the shield to the second bobbin. When the first and second bobbins are juxtaposed with their openings adjacent to each other, the first and second receiving recesses are in communication with each other, while the first and two center through-holes extend in parallel to each other. | 05-12-2016 |
| 20160189846 | REACTOR - A reactor includes a reactor body and a heat sink. The reactor body includes coil wire wound around a core. The heat sink is fixed to the reactor body through a heat transfer sheet. The heat sink includes a restricting wall for the heat transfer sheet such that expansion of the heat transfer sheet in a first direction is restricted more than expansion of the heat transfer sheet in a second direction. The first direction is an extending direction of the coil wire on a surface of the reactor body, which abuts on the heat transfer sheet. The second direction is an axis direction of the coil wire. | 06-30-2016 |
