以上のように、実施の形態1では、電磁石3の内側鉄心50と外側鉄心40とを分離し、内側鉄心50の4つの角部Bに、4つの分割ボビン10を取付けて、電磁コイル30を形成しているので、サイズの異なるブレーキにおいて、内側鉄心50の寸法が異なる場合であっても、同一の分割ボビン10を用いて電磁コイル30を形成することができる。これにより、多種類のボビンを製作する必要がなくなるので、1つの分割ボビン10の金型のみ製作すればよく、金型の製作費用と製造工数を削減することができる。さらに、分割ボビン10を用いることで、従来のボビンよりも金型の大きさを小さくすることができ、成形品に発生する成形歪が低減されて、ボビンにコイルを巻回した際の、コイルの整列性を向上させることができる。
As described above, in the first embodiment, the inner iron core 50 and the outer iron core 40 of the electromagnet 3 are separated, the four divided bobbins 10 are attached to the four corners B of the inner iron core 50, and the electromagnetic coil 30 is made. Since it forms, even if it is a case where the dimension of the inner iron core 50 differs in the brakes from which size differs, the electromagnetic coil 30 can be formed using the same division | segmentation bobbin 10. FIG. Accordingly, since it is not necessary to manufacture various types of bobbins, only the mold of one divided bobbin 10 needs to be manufactured, and the manufacturing cost and manufacturing man-hour of the mold can be reduced. Further, by using the divided bobbin 10, the size of the mold can be made smaller than that of the conventional bobbin, the molding distortion generated in the molded product is reduced, and the coil is wound when the coil is wound around the bobbin. Alignment can be improved.
なお、実施の形態1では、分割ボビン10の凹部Aの開口部の上下に突起部aを設け、内側鉄心50の上面と下面の両方に溝部bを設けたが、これに限るものではない。例えば、凹部Aの開口部の上下のうち、一方に突起部aを設け、内側鉄心50の上面と下面の一方に溝部bを設けるようにしてもよいし、分割ボビン10の方に溝部bを設け、内側鉄心50の方に突起部aを設けてもよい。また、実施の形態1では、分割ボビン10の突起部aを、天板11と底板12の端部に沿って直線状に形成したが、これに限るものではない。例えば突起部aを、天板11と底板12の端部に沿って断続的に形成した、複数の凸部としてもよい。突起部aが、断続的に形成された複数の凸部の場合、内側鉄心50の溝部bは、断続的に形成された、複数の凹部としてもよい。
In the first embodiment, the protrusions a are provided above and below the opening of the recess A of the divided bobbin 10 and the grooves b are provided on both the upper surface and the lower surface of the inner iron core 50. However, the present invention is not limited to this. For example, the protrusion a may be provided on one of the upper and lower sides of the opening of the recess A, and the groove b may be provided on one of the upper surface and the lower surface of the inner iron core 50, or the groove b may be provided on the divided bobbin 10. Protruding part a may be provided on the inner iron core 50. In the first embodiment, the protrusion a of the divided bobbin 10 is linearly formed along the end portions of the top plate 11 and the bottom plate 12, but the present invention is not limited to this. For example, the protruding portion a may be a plurality of convex portions formed intermittently along the end portions of the top plate 11 and the bottom plate 12. When the protrusion a is a plurality of protrusions formed intermittently, the groove b of the inner iron core 50 may be a plurality of recesses formed intermittently.
また、実施の形態1では、分割ボビン10を、内側鉄心50の4つの角部Bに取り付けているが、これに限るものではない。例えば、汎用性は低くなるが、実施の形態1の分割ボビン10を2つ結合したような形状の、2分割の分割ボビンとして、4つの角部Bのうち、2つの角部Bに対して1つの分割ボビンを取付けるような形状にしてもよい。また、実施の形態1における分割ボビン10をさらに上下に分割して、8分割の分割ボビンとして、4つの角部Bの上下に分割ボビンを取付け、ボビン付内側鉄心20を構成しても良い。8分割とすることで、高さの異なる内側鉄心50についても、1種類の分割ボビンで対応することができる。なお、8分割の分割ボビンを内側鉄心50に取り付ける場合には、分割ボビンの突起部aを、凹部Aの開口部の側壁に沿って設け、内側鉄心50の溝部bを、角部Bの両側面に設けるなど、突起と溝部の形状や位置を適宜変更、追加して、分割ボビンを内側鉄心50に固定できるようにすればよい。また、実施の形態1では、4つの分割ボビン10を同一形状としたが、これに限るものではない。例えば、左右で一対となる、異なる形状の分割ボビンを組み合わせて使用するようにしても良い。
In the first embodiment, the divided bobbin 10 is attached to the four corners B of the inner iron core 50. However, the present invention is not limited to this. For example, the versatility is low, but two divided bobbins having a shape that combines two divided bobbins 10 according to the first embodiment are divided into two corners B out of four corners B. You may make it the shape which attaches one division | segmentation bobbin. Further, the divided bobbin 10 according to the first embodiment may be further divided into upper and lower parts, and divided bobbins may be attached to the upper and lower parts of the four corners B as eight divided bobbins to constitute the inner iron core 20 with the bobbin. By dividing into eight parts, the inner iron cores 50 having different heights can be handled with one kind of divided bobbin. In addition, when attaching the divided | segmented bobbin of 8 divisions to the inner side iron core 50, the protrusion part a of a division | segmentation bobbin is provided along the side wall of the opening part of the recessed part A, and the groove part b of the inner side iron core 50 is provided on both sides of the corner | angular part B. The split bobbin may be fixed to the inner iron core 50 by appropriately changing or adding the shape and position of the protrusion and the groove, such as by providing on the surface. In the first embodiment, the four divided bobbins 10 have the same shape, but the present invention is not limited to this. For example, you may make it use combining the division | segmentation bobbin of a different shape which makes a pair on right and left.
さらに、実施の形態1では、内側鉄心50において、段部50aの中央側の端部に溝部bを形成したが、これに限るものではない。例えば、図11に示すように、段部50aを、内側鉄心50の内側に向かうにつれて、内側鉄心50の厚みが薄くなる傾斜面50bとし、分割ボビン10と内側鉄心50とが、突起部aと、傾斜面50bとの摩擦により係合するようにしてもよい。この場合、分割ボビン10の突起部aにかえて、凹部Aの内側の上面および下面を、傾斜面50bに倣う傾斜面として、凹部Aの内側の上面および下面と、傾斜面50bとの摩擦により係合させても良い。
Furthermore, in Embodiment 1, although the groove part b was formed in the center side edge part of the step part 50a in the inner side iron core 50, it is not restricted to this. For example, as shown in FIG. 11, the stepped portion 50a is formed as an inclined surface 50b in which the thickness of the inner iron core 50 becomes thinner toward the inner side of the inner iron core 50, and the divided bobbin 10 and the inner iron core 50 are formed with the protrusion a. The engagement with the inclined surface 50b may be achieved by friction. In this case, instead of the protrusion a of the divided bobbin 10, the upper surface and the lower surface inside the recess A are inclined surfaces following the inclined surface 50b, and the friction between the upper surface and the lower surface inside the recess A and the inclined surface 50b is caused. It may be engaged.
