The attachment has a member to be attached which is provided with a hole into which the leg piece is inserted, and the attachment member which is inserted into the hole and protrudes from the member to be attached heats and deforms the tip of the leg piece to attach the coil bobbin to the attached member. It is characterized by being fixed to a member.
（実施例）
そこで以下に本発明の詳細を図示した実施例に基づいて
説明する。(Example) The details of the present invention will be described below based on illustrated examples.
第１図は、ワイヤドツトプリンタヘッドのコイルボビン

ともに熱可塑性樹脂によって一体的に形成されている。FIG. 1 shows an embodiment of the present invention applied to a coil bobbin block of a wire dot printer head. In the figure, reference numeral 1 indicates a coil bobbin consisting of a winding drum 2 and flanges 3.3 at both ends thereof. The main body 1 is integrally formed of thermoplastic resin with legs 4.4 projecting outward from the collar 3 and forming a characteristic part of the invention.
そして、これらの脚片４．４は、被取付部材であるコア
ブロック６の孔７を貫通してその裏面に添設されたプリ

２に巻回した巻線５の端部を巻付けて回路パターンとの
接続を図るように構成されている。These leg pieces 4.4 are formed in such a length that they pass through the hole 7 of the core block 6, which is the member to be attached, and protrude onto the printed circuit board 9 attached to the back surface of the core block 6. It is configured so that the end portion of the winding 5 wound around the body 2 is wound to connect with a circuit pattern.
したがって、このように構成されたコイルボビン本体１

た巻線５の端部をプリント回路のアイランドに半田付け
すると、脚片４は熱伝導度と熱容量の小さな樹脂材によ

両者を接合し、また、この際脚片４の先端をコテ等の先
で押圧すれば、熱によって柔かくなった脚先端部は、基
板９上に膨頭部ａを形成して一体的に固定される。Therefore, the coil bobbin body 1 configured in this way
When the winding 5 is wound around the end of the wire 5 and the end thereof is wrapped around the leg piece 4 and then press-fitted onto the core 8, the leg piece 4.4 integrally formed on the flange part 3 of the main body 1 becomes Since it penetrates through the hole 7 provided in the core block 6 and protrudes onto the surface of the printed circuit board 9 attached to the back surface of the core block 6, the ends of the winding 5 exposed on the surface of the circuit board 9 together with the leg pieces 4 are printed. When soldered to the island of the circuit, since the leg piece 4 is made of a resin material with low thermal conductivity and heat capacity, the solder instantly solidifies and joins the two pieces. When the tip is pressed with the tip of a trowel or the like, the tip of the leg, which has become soft due to heat, forms a swollen head a on the substrate 9 and is fixed integrally.
なお、以上は熱可塑性樹脂材をもってコイルボビン本体

の取付けをすることができる。The above is an explanation of an embodiment in which the coil bobbin body 1 is made of a thermoplastic resin material, but if the leg piece 4 is extremely thin, only the leg piece 4 or the leg piece 4 and the coil bobbin body 1 are made of heat-resistant resin. It may be made of a material, and even if it is made of such a material, it can be attached in the same way as described above.

It is possible to instantly solder the coil bobbin to an island, etc., and at the same time, by crushing the tip of the leg melted by the heat, the coil bobbin can be easily and reliably fixed to a circuit board, etc.
