Abstract

The coil structure, the coil winding, the coil part and the manufacturing method of the coil winding provided by the present invention, even if two winding parts and the connecting wire part connecting the two winding parts are formed, there is no need to leave redundant parts due to the existence of the connecting wire part. space; the coil structure (200) has a first winding portion (21), a second winding portion (23) wound in the same winding direction as the first winding portion (21), and a first winding portion connected to (21) and the connection line predetermined portion (22A) of the second winding portion (23); the connection line predetermined portion (22A) has an interval regulation portion (222), a first connection portion (221) and a second connection portion (223) , the interval regulation part (222) regulates the interval between the first winding part (21) and the second winding part (23), and one end side of the first connection part (221) is bent along the edge with the interval regulation part (222) The other end side is connected to the first winding part (21) on one side in the axial direction of the first winding part (21), and one end side of the second connecting part (223) is bent along the edge with the interval regulation part ( 222) connection, and the other end side in the axial direction of the second winding portion (23) is connected to the second winding portion (23).

Description

technical field [0001] The present invention relates to a coil winding, a coil component and a method for manufacturing the coil winding. Background technique [0002] In a power generation device utilizing natural energy, a power supply device, and a drive device that drives an automobile wheel by an electric motor, coil components (reactors) are used in circuits to improve power factors or eliminate noise. Among the above-mentioned coil parts, flat wires are generally used for the purpose of coping with large currents and improving the duty cycle. As said coil component using a flat wire, the coil component described in patent document 1 exists. [0003] [Prior Art Literature] [0004] 【Patent Literature】 [0005] Patent Document 1: Japanese Gazette, Patent No. 3398855 (cf. Figure 4 ~ Figure 6 ) [0006] In the configuration of Patent Document 1, it is provided that a twisted portion is formed in a portion (connecting wire portion) between the first winding portion (f...
