部４Ｃがモールド部ｌ４から突出している。FIGS. 8 and 9 show a conventional coil bobbin of this type, and as shown in the figures, a pair of L-shaped hooks are formed on the outer surface of one collar 2 of the bobbin body 1 made of synthetic resin. The horizontal part 4A of the terminal 4 is provided on each hook part 3.
The terminal 4 is attached to the collar 2 by press-fitting and locking the terminal 4. After that, the coil 1 wire 6 is wound around the cylindrical portion 5 of the bobbin body 1, and the winding start and end ends of the coil winding 6 are connected to the terminal 4. It is formed by wrapping it around the short vertical part 4B and soldering it. In the figure, 4C is a long vertical part of the terminal 4 for connection to the outside, and 7 is a groove formed on the periphery of the collar 2 for guiding the end of the coil S wire 6 to the terminal 4. FIG. 10 and FIG. 1) show an example in which the coil bobbin 8 is used in a rotation detection device for detecting rotation such as vehicle speed.
In the figure, reference numeral 9 denotes a cylindrical case made of metal, for example, which is fixed to the transconsin side, and this case 9 supports a rotating shaft 1l to which rotation of the transmission is transmitted via a bearing 10. A magnet 12 is located inside the case 9 and fixed to the rotating shaft l1, and a plurality of N poles and a plurality of S poles are alternately magnetized in the circumferential direction. Reference numeral 13 denotes a detection section molded with a resin mold section 14, and is disposed inside the case 9. This detection section 13 includes a coil bobbin 8 and a first. second yoke 15,
It consists of 16. The first yoke l5 has a case shape with a flat part 15A and a circumferential side part 15B, and the circumferential edge of the circumferential side part 15B has a plurality of arm rods corresponding to one of the S and N poles of the magnet l2. 15C are extended at equal intervals, and a recess l5D is formed in the flat part 15A, and the case-shaped part of the first yoke 15 is externally fitted onto the coil bobbin 8 from the terminal 4 side, and the recess 15D is inserted into the bobbin body. The arm rod 15C is fitted into the cylindrical portion 5 of No. 1 and reaches the circumferential side of the magnet 12. The second yoke l6 has a plurality of leg rods 1 on the periphery of the flat part 16A corresponding to the other magnetic pole of the magneto rod l2.
6B are extended at equal intervals, and the flat portion 16A has convex portions 1.
6G is formed, and the flat part 16 of the second yoke 16
A is brought into contact with the collar 2 on the side that does not have the terminal 4, the convex part 16c is fitted into the cylindrical part 5, and the leg rod 16B is placed between the arm rod 15C of the first yoke 15, and then the concave part l5 and the convex The portion 16C is abutted and connected by spot welding. In this state, the magnetic flux flows through the arm rod 15C, the circumferential side surface 15B, the flat portion 15A, the concave portion 15D1, the convex portion 16C1, the flat portion 16A1, and the leg rod 16B, and the rotation of the transmission is transmitted to the rotating shaft 3, and the rotation of the transmission is transmitted to the rotating shaft 3. A change in the magnetic pole due to rotation is detected as a change in the excitation current flowing through the coil body 6, and is output from the terminal 4 as a vehicle speed pulse. In this case, the first and second yokes 15. 16 and a coil bobbin 8.
The long vertical portion 4C of the terminal 4 protrudes from the molded portion l4.

を提供することを目的とする。In the above conventional technology, a bobbin body 1 with a hook portion 3 is provided.
and the terminal 4 are made separately, and then the terminal 4 is attached to the hook part 3.
Since it is attached to the bobbin body 1 by locking it to the bobbin body 1,
The positional accuracy of the terminal 4 is low, and when insert molding the resin mold part 14 to cover the coil bobbin 8 with a resin mold material as shown in FIG. If the long vertical portion 4C cannot be assembled or is forcibly assembled, there is a problem in that it becomes difficult to remove it from the mold. Additionally, in order to solve this problem, it is possible to form the terminal assembly hole of the mold with an extra dimension, but in this case, resin may enter the terminal assembly hole and the vertical part 4C of the terminal 4 There is a problem in that the surface is covered with a resin film, making post-processing time-consuming. Therefore, an object of the present invention is to provide a coil bobbin with high terminal positioning accuracy.
