    • PROBLEM TO BE SOLVED: To provide a method of manufacturing a coil device which reduces deterioration of an insulator during the manufacture of the coil device while facilitating the manufacture.SOLUTION: Planar insulating sheets 3 are inserted into a single conductor 2 formed in a solenoidal coil shape from a direction intersecting with the direction of a winding axis A of the conductor 2. In this process of inserting the insulating sheets, the insulating sheets 3 may be inserted from both sides opposing across the winding axis of the conductor 2. In addition, the method may include stretching the conductor 2 in the winding axis direction, inserting the insulating sheets 3 into the conductor 2 in the stretched state, and releasing the conductor 2 from the stretched state. The insulating sheets 3 may have a semicircular or approximately semicircular shape having a radius greater than or equal to the radius of the conductor.
    • 要解决的问题:提供一种线圈装置的制造方法,其在制造线圈装置的同时减少绝缘体的劣化,同时有利于制造。 解决方案:将平面绝缘片3从与导体2的卷绕轴线A的方向相交的方向插入到形成为螺线管线圈形状的单个导体2中。在插入绝缘片的过程中,绝缘 片材3可以从导体2的缠绕轴线相对的两侧插入。此外,该方法可以包括在卷绕轴线方向拉伸导体2,将绝缘片3以拉伸状态插入导体2中,以及 将导体2从拉伸状态释放。 绝缘片3可以具有半径大于或等于导体半径的半圆形或近似半圆形。 版权所有(C)2013,JPO&INPIT
