As shown in FIG. 5, a three-layer insulated wire having a high insulation property (hereinafter referred to as a reference numeral 6)

The three-layer insulated wire 6 is pulled out from one end of the winding portion 3a on the side of one flange 3b, and is drawn along the surface of the one flange 3b. After being crawled, since it is entangled with the pin 4 provided on the opposite side of the one flange 3b, at the time of soldering, as shown in FIG. There is a problem that the insulated wire 6 rises from the portion of the insulated wire 6 that is entangled with the pin 4 to the vicinity of the wire 2 in the winding portion 3b.

機能が低下してしまうことが想定される。[0007] Since the molten solder 7 burns off the insulating coating layer of the three-layer insulated wire 6, if the molten solder 7 rises to the vicinity of the wound wire 2 as described above. It is assumed that the insulation distance between the three-layer insulated wire 6 and the single-layer insulated wire 2 is shortened as indicated by the symbol M in FIG.

前述した絶縁距離がさらに狭められてしまい易い。The destruction of the insulating coating layer of the three-layer insulated wire 6 is caused not only by direct burnout with solder but also by the transmission of heat from the solder through the electric wire. Proceed forward from the rising tip,
The aforementioned insulation distance is likely to be further reduced.

鍔部３ｂの側面の範囲内に収めることが考えられる。As an example for solving such a problem, as shown in FIG. 6, the thickness of one flange 3b along which the three-layer insulated wire 6 is extended is increased to thereby increase the thickness of the three-layer insulated wire. It is conceivable to lengthen the draw-out length of No. 6 so that the above-mentioned solder rise falls within the range of the side surface of the flange portion 3b.

It is enlarged to the distance between the single-layer insulated wire 2 and the side surface of the one flange portion 3b, thereby preventing the insulation function from lowering.
