Description

  The present invention relates to a winding method and apparatus, and more particularly to a winding method and apparatus for winding a wire around a bobbin between both projecting edges of a core.

  In general, when the bobbin between both projecting edge portions of the core winds up the wire material, the wire material usually enters from the projecting edge portion which becomes the incoming wire end during winding, and then the wire material at the incoming wire end first enters the incoming wire end protrusion. After the solder is fixed to the electrode on the edge, the wire is wound around the bobbin a predetermined number of times, and the other end of the wire is further soldered to the electrode on the protruding end edge, and the wire on the core is Winding is complete. In the winding process in which one or more wires are wound around the bobbin of the core at the same time, usually, a plurality of electrodes are installed on the protruding edge portion serving as the incoming wire end and the protruding edge portion serving as the outgoing wire end. It is necessary to combine the protrusions to form a folded protrusion of the wire.

  Patent No. I237278 “Common Mode Choke Coils”, which is a conventional technique, discloses a coil having a plurality of electrodes.
