Embodiment Construction

[0043] An example of the flat insulated wire 10 of this embodiment is shown in figure 1 . An example of an edgewise coil 20 using this flat insulated wire 10 is shown in figure 2 . When looking down, figure 2 The edgewise coil 20 is an example of a racetrack shape in which both ends of a pair of linear portions are connected by semicircular portions. The shape of the edgewise coil 20 using the flat insulated wire 10 of this embodiment is not limited to figure 2 shape. These are edge-to-edge coils of various curled shapes, such as a rectangular shape with four corners curled into a circular arc or a circular shape when viewed from above.

[0044] Such as figure 1 As shown, the thickness L1 of one side of the flat insulated wire 10 of this embodiment is formed thicker than the thickness L2 of the other side, as shown in FIG. figure 2 As shown, the flat insulated wire 10 is wound (curled) upright with the thicker side as a curled outer peripheral portion 10A and the ...

Abstract

The invention provides a flat coil flat insulated electric wire and a manufacturing method for the same. The flat insulated electric wire is characterized in that the wall thickness of a conductive wire rod on the bend external peripheral part is greater than the wall thickness of the conductive wire rod on the bend internal peripheral part; the insulated coating thickness of the bend external peripheral part is greater than the insulated coating thickness of the bend internal peripheral part; preferentially, the insulated coating thickness of the external peripheral part is more than 1.5 times of the insulated coating thickness of the internal peripheral part; and the wall thickness of the conductive wire rod and the insulated coating part of the external peripheral part is 1.2 to 1.7 times of the wall thickness of the conductive wire rod and the insulated coating part of the internal peripheral part.

Description

technical field [0001] The present invention relates to a flat insulated wire for edgewise coils capable of maintaining good insulation without making the thickness of the insulating coating on the outer peripheral side less than the thickness of the insulating coating on the inner peripheral side when crimping a flat insulated wire for edgewise coils. Flat insulated wires and methods of manufacture thereof. [0002] This application claims priority based on Patent Application No. 2014-217854 for which it applied in Japan on October 24, 2014, and uses the content for this specification. Background technique [0003] Such as Figure 6 As shown, in the flat insulated wire 60 , an insulating coating 64 is provided on the surface of a conductive wire 63 having a quadrilateral cross section surrounded by a long side 61 and a short side 62 . The edgewise coil 65 is a coil wound with the short side 62 of the flat insulated wire 60 as a fulcrum side. In the flat coil 65, since the...
