MULTIPLE-WIRE WINDING METHOD, MULTIPLE-WIRE WINDING DEVICE, AND WOUND COIL COMPONENT

WIPO Patent Application WO/2015/178263

A1

[Problem] To provide a multiple-wire winding method and a multiple-wire winding device that make it possible to reduce both damage done to wires and the risk of short-circuits between said wires and electrodes at different potentials. [Solution] In this winding method, starting sections of a plurality of wires are first guided from the outside of a flange on one end of a core to the inside thereof and then laid out on top of and connected to electrodes on said flange. The wires are guided laterally with respect to the axis of the core and are wound around a winding-core section together. Next, a wire-hooking implement is inserted into a groove in a flange on the other end of the core, ending sections of the wires are guided from the inside of said flange to the outside thereof, and a tip section of the wire-hooking implement is used to hook the ending section(s) of at least one but not all of the wires and bend said ending section(s) while keeping the wire(s) under tension. The ending sections of the plurality of wires are then laid out on top of and connected to corresponding electrodes on the flange on the other end of the core. By bending the wire ending section(s) laterally, the risk of short-circuits with electrodes at different potentials is reduced.
