巻線機にて行なう場合の改良構造に関する。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a winding body, such as an ignition coil, in which the winding start end of the coil is connected to a terminal outside the bobbin when the coil is wound around a bobbin. In detail, the present invention relates to an improved structure for winding the winding start end onto a terminal and winding a coil onto a bobbin using an automatic winding machine.

ーミナルをボビンから相当離隔させているのが通例であ
る。In this type of winding body, which is conventionally well known, the terminal forms a simple columnar body, and the winding start end is wound around this terminal.
Next, when winding the coil onto the bobbin, if this is done using an automatic winding machine, the axial length of the terminal must be adjusted to give the winding head enough stroke to properly wind the starting end of the winding around the terminal. It is customary to make the terminal long or to place this terminal at a considerable distance from the bobbin.

てきた。However, in recent years, various restrictions have been added to this type of winding body, and as mentioned above, it is not possible to increase the axial length of the terminal or to position the terminal at a considerable distance from the bobbin. There are now cases where this is not possible.
本発明は上記点に鑑み、ターミナル自体の長さやターミ
ナルとボビンとの離隔距離を短かくすることができる巻
線体を提供することを目的とする。In view of the above-mentioned points, it is an object of the present invention to provide a winding body that can shorten the length of the terminal itself and the distance between the terminal and the bobbin.

にする。In order to achieve the above object, the present invention has devised the structure of a terminal around which the winding start end of a coil is wound. The coil wire receiver has a groove recessed in the bobbin axial direction from the higher side of the top portion, and a neck formed narrowly by this groove, and the winding start end is wound around this neck. Do it like this.

The winding nozzle 7 moves above the terminal 2 from the position 7a to the position 7b.
position, as shown by arrow A, along the flange 31a in a direction perpendicular to the bobbin axis direction. At this time, the coil winding 50 that forms the winding start end 5a is fed out from the nozzle 7.
Since the top 21 of the terminal 2 is an inclined surface 21a, the coil strand holder slides smoothly on the sloping surface 21a, and the coil strand holder is held in the part 22. In other words, the coil wire 50 is reliably guided toward the bobbin side of the terminal 2 by the inclined surface 21a, and the coil winding 50 does not fall onto the base of the terminal due to the receiving portion 22.
