  • Wire-arranging pin and winding frame and transformer having same
    Patent number: 7456718
    Abstract: A wire-arranging pin is mounted on a winding frame for facilitating fixing an outlet part of a winding coil. The winding coil is wound around the winding frame. The wire-arranging pin includes a first connecting part, a main fixing part and a second connecting part. The first connecting part has a first end and a second end, wherein the first end is coupled to the winding frame. The main fixing part is coupled to the second end of the first connecting part and has a first notch. The outlet part of the winding coil penetrates through the first notch to be held by the main fixing part. The second connecting part has a first end coupled to the main fixing part.
