Abstract
Description
【発明の詳細な説明】 本発明は点火コイルボビンの改良に関する。[Detailed description of the invention] The present invention relates to improvements in ignition coil bobbins.
従来点火コイルボビンは、−次コイル巻線用ボビンと、
二次コイル巻線用ボビンとの２ケを使用し、各々にコイ
ルを巻付けた後、２ケを組付て点火コイルを構成してい
た。The conventional ignition coil bobbin consists of a -th coil winding bobbin,
Two pieces, including a bobbin for winding the secondary coil, were used, and after winding a coil around each, the two pieces were assembled to form an ignition coil.
ところが、上述した従来のものでは、ボビンを作るため
の成形片が２ケタ・要であるので、２輪車用等の多種少
量生産のものでは型代が高くなり、コストア、７プの要
因となっているという問題が洸った。However, with the above-mentioned conventional method, the number of molded pieces required to make the bobbin is two digits, so the cost of the mold becomes high when producing a wide variety of products in small quantities, such as those for motorcycles, which leads to a cost increase. The problem of what is happening has come up.
本発明は上記の問題を解決するため、−次コイルと二次

とする。In order to solve the above problems, the present invention adopts a bobbin structure that can hold both a primary coil and a secondary coil, and makes it possible to make an ignition coil with a single bobbin mold. It is an object of the present invention to provide an inexpensive ignition coil that can hold the next side coil, reduce the cost of a bobbin mold for the ignition coil, and reduce the number of parts.
以下本発明を図に示す実施例について説明する。The present invention will be described below with reference to embodiments shown in the drawings.
図中１は一次、二次コイル２．３の両方を保持するボビ
ンで合成樹脂で成形して作られたおり、該ボビン１の外
径部には軸方向に複数の溝に分割された二次コイル巻線
部１ａが形成され、二次コイル３が谷溝に順次巻付けで
ある。また、ボビン１の内径部には筒状の空間部１ｂが
設けてあり、あらかじめ巻線成形された一次コイル２が
軸方向一端より挿入しである。４は樹脂製のケースで、
少なくとも前記ボビン１の内径１ｃに挿入する筒状部４

アで、その端の一板６ａの両端が折り曲げられ、コイル
本体の軸方向の動きを固定している。In the figure, 1 is a bobbin that holds both the primary and secondary coils 2.3 and is made of synthetic resin. A secondary coil winding portion 1a is formed, and the secondary coil 3 is sequentially wound around the valley groove. Further, a cylindrical space 1b is provided in the inner diameter portion of the bobbin 1, and a primary coil 2 which has been wound in advance is inserted from one end in the axial direction. 4 is a resin case,
A cylindrical portion 4 inserted into at least the inner diameter 1c of the bobbin 1
a and the contact surface 4b that the axial end surface 1d of the bobbin 1 contacts.
It will be equipped with. 5 is an insulating material poured into the case 4, which insulates between the wires and fixes the entire structure. Reference numeral 6 denotes a laminated core, and both ends of one plate 6a at the end thereof are bent to fix the movement of the coil body in the axial direction.
前記構成において、ボビン１が一次コイル２及び二次コ
イル３の両コイルを固定できるので、従来はボビン２ケ
使用していたのが１ケですむようになり、部品点数の低

ルが提供できる。In the above configuration, since the bobbin 1 can fix both the primary coil 2 and the secondary coil 3, only one bobbin is required instead of the conventional two, reducing the number of parts and bobbin mold cost. Therefore, an inexpensive ignition coil can be provided.
