  • Publication number: 20150137927
    Abstract: A transformer skeleton and a winding method using the same are provided. The transformer skeleton includes at least one limiting hook. The limiting hook and a pin of the transformer skeleton are located on a same side of the transformer skeleton. A wire, which is led out from a winding groove of the transformer skeleton, electrically contacts the pin and passes through the limiting hook. The limiting hook is used to prevent the wire from moving upward. The advantage of the transformer skeleton is that the transformer skeleton disposes at least one limiting hook which is used to prevent the wire from moving upward and only a single layer of the wire contacts the pin in order to reduce the height of a tin cone. The transformer skeleton can decrease the height of the tin cone by 70%˜80%, thereby efficiently decreasing the height and width of the transformer.

  • Publication number: 20150130576
    Abstract: U-shaped cores and fasteners are embedded in resin members, and brackets provided at respective ends of the fasteners protrude from the resin members. By fixing the brackets and a casing with screws, a reactor main body and the casing are fixed together. Openings formed by a partition wall that suppresses a direct application of a resin flowing from resin-filling portions to the fasteners are provided between the respective fasteners and the respective resin-filling portions. A protrusion extending in an opposite direction to a core and in parallel with the partition wall is provided between the resin-filling portions and the partition wall. The resin flowing from the resin-filling portion flows in between a core upper face and the fastener, and between a fastener surface located behind the partition wall and the internal surface of a die.
