位置決めが容易で確実な結合が可能となる。First, according to the present invention, since the core case 2 and the pedestal 3 are joined by fitting the fitting portion 5 and the holding portion 4, the positional deviation between the two is unlikely to occur at the time of joining, and variation in dimensions can be reduced. . Next, the core case 2 that holds the annular core includes the fitting portion 5 on the axial side of the annular core.
For this reason, in the present invention, since there is no flat plate-shaped support portion as in the conventional case, winding on the core case before assembly is easy. Further, according to the present invention, the axial side 1 of the annular core having the fitting portion is
When 0 is a plane shape, positioning of the joint portion is easier and reliable coupling can be performed, as compared with the case where the fitting portion 5 is provided on the outer peripheral side of the annular core having a curved surface shape.

も可能である。In addition, since the fitting portion 5 is located on the axial side of the annular core, the size of the pedestal coil in the height direction is not increased due to the structure of the fitting portion and the holding portion. That is, in the coil with pedestal of the present invention, since the core case and the pedestal are coupled on the axial side of the annular core, it is possible to arrange the bottom plate 15 and the core case so that they are in contact with each other. With respect to the height of the single unit (to the total size of the diameter of the outer periphery of the core case and the thickness of the winding applied to the core case), the increase in the dimension in the height direction of the coil with the pedestal after assembly is substantially It is also possible to use only the thickness of the bottom plate 15.

ースをより安定して固定することが可能となる。Further, it is preferable that the fitting portion and the holding portion are fitted to each other by fitting the concave portion and the convex portion, respectively, which facilitates the assembly. Since the positional relationship between the coil and the pedestal is uniquely determined by the fitting of the concave portion and the convex portion, it is possible to achieve high precision of the mounting dimension. In this case, it is preferable that the convex portion or the concave portion provided in the fitting portion has a shape extending in the radial direction of the annular core.
As shown in FIGS. 2 and 3, by forming the convex portion 7 or the concave portion 6 in a shape that is extended in the radial direction, the core case is made more resistant to external load or vibration having a component perpendicular to the extended direction. It becomes possible to fix it stably.

際の作業が困難となる。In the fitting of the concave portion and the convex portion, it is preferable that the members constituting the holding portion or the fitting portion are elastically deformed to be fitted to each other. As a result, it is possible to reduce the play of the members required at the time of assembly, so that rattling is unlikely to occur after assembly and the assembly is easy. In the present invention, examples of the material having appropriate elastic modulus and strength include glass-reinforced thermoplastic resin (eg PBT resin PET resin). When the concave portion and the convex portion are fitted together, the larger the elastic modulus of the member, the more stable the joining and fixing. However, if the elastic modulus is large, it becomes difficult to fit the convex portion into the concave portion.

る。Therefore, in the present invention, the fitting portion 5 or the holding portion 4 having the concave portion 6 guides the convex portion 6 when the convex portion 7 and the concave portion 6 are fitted to each other, as shown in FIGS. The guide groove 12 is preferably provided, and one end of the guide groove 12 opens from the end of the fitting portion 5 or the holding portion 4 and the other end communicates with the recess 6. Sliding the convex portion in the guide groove allows the elastic deformation of the member to be suppressed compared to the case without the guide groove, and the fitting can be performed even when a member having a large elastic modulus is used. It becomes easy to fit with. As a result, without increasing the number of steps when assembling the coil with the pedestal,
It is possible to obtain a coil with a pedestal with more stable coupling.

を利用して巻線を固定することが出来る。Further, in the present invention, it is preferable that the through groove has a winding engaging portion extending in a direction different from the opening direction.
The winding engaging portion is a portion where the winding engages with the through groove by its own elastic force. By providing the winding engaging portion in a direction different from the opening direction of the through groove, it is difficult for the winding end portion, which is once engaged with the winding engaging portion, to come off the end portion of the opened through groove.
The through-groove having the winding engaging portion extending in a direction different from the opening direction has, for example, a shape having a bent portion, and more specifically, as shown in FIGS. Is the winding engaging portion 20 on the opposite end side,
The winding can be fixed from the open portion of the through groove to the innermost portion by utilizing the elasticity of the winding itself.

However, by making it 1 mm to 4 mm shorter than the coil thickness (the coil thickness in the axial direction of the core case), it is pressed against the terminal end of the through groove. Further, if the terminal is positioned by this configuration, the terminal position can be determined even with a wire diameter smaller than the groove, and versatility with respect to the wire diameter can be provided.
