型磁気ヘツドボビンに関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a magnetic head bobbin, and more particularly to a connected magnetic head bobbin in which a pair of bobbin main bodies are connected and integrated at a connecting portion.

ア８の先端にギヤツプＧを形成している。(Prior Art) A magnetic head using a connected bobbin as shown in FIG. 3 has been known. In this figure, a winding 4 is applied to each connected bobbin 3 in which a pair of bobbin main bodies 1 are connected and integrated through a connecting part 2 at one of the brim parts 5A, and the drawn end of the winding 4 is connected to the bobbin 3. A coil 7 is formed by connecting to a terminal pin 6 implanted in the other flange portion 5B of the main body portion 1,
A pair of C-shaped cores 8 are inserted through the coil 7, and a gap G is formed at the tip of the C-shaped cores 8.

うにする。このため、第３図に示すごとき連結型
ボビン３は巻線作業が容易でコスト低減を図る上
で効果がある。 In this case, when winding the connected bobbin 3 with an automatic winding machine, as shown in FIG. Winding is performed as if it were a single bobbin, and then the bobbin is returned to the parallel state as shown in FIG. 3, and the C-shaped core 8 is fitted. For this reason, the connected bobbin 3 shown in FIG. 3 is easy to wind and is effective in reducing costs.

一方、第５図に示すごとくそれぞれ単独のボビ
ン１１にそれぞれ巻線４を施して各巻線４を直列
接続してＣ型コア８を挿通する構造も知られてい
る。 On the other hand, as shown in FIG. 5, there is also known a structure in which each individual bobbin 11 is provided with a winding 4, the windings 4 are connected in series, and a C-shaped core 8 is inserted through the windings 4.

（考案が解決しようとする問題点）ところで、第３図に示すごとき連結型ボビン３
の場合には、連結部２に可撓性が必要である。こ
のため、従来はボビン全体を可撓性を持つた樹脂
で成型していた。しかし、可撓性を持つた樹脂は
通常耐熱性が良好でなく、巻線４の引き出し線を
端子ピン６にはんだ付けする場合、はんだ付け温
度（約360℃）近辺となると、耐熱性が悪いため、
熱で熔融、軟化して端子ピン６がぐらついたり曲
がつたりする問題点があつた。(Problems to be solved by the invention) By the way, the connected bobbin 3 as shown in FIG.
In this case, the connecting portion 2 needs to be flexible. For this reason, conventionally the entire bobbin has been molded from a flexible resin. However, flexible resin usually does not have good heat resistance, and when the lead wire of winding 4 is soldered to terminal pin 6, it has poor heat resistance when the temperature is close to the soldering temperature (approximately 360°C). For,
There was a problem that the terminal pin 6 would become loose or bent due to melting and softening due to heat.

また、第５図の独立型ボビンを用いた構造は、
独立にボビン１１を２個用いる構造であるため、
樹脂の選択は自由であり耐熱性樹脂を採用するこ
とも可能であるが、巻線作業が面倒となり、コス
ト高となる欠点がある。 In addition, the structure using the independent bobbin shown in Fig. 5 is as follows.
Since the structure uses two bobbins 11 independently,
Although the resin can be freely selected and heat-resistant resins can be used, the disadvantage is that the winding work is troublesome and the cost is high.

The first collar portion to be connected is made of flexible resin, the second collar portion on which the terminal pin is provided is made of heat-resistant resin, and one of the first collar portions and the second collar portion is made of a heat-resistant resin. An object of the present invention is to provide a magnetic head bobbin which facilitates winding work by fitting the terminal pin into a cylindrical part of the bobbin extending from the other flange, and which does not cause the terminal pins to wobble or tilt due to heat during soldering. It is something to do.
