The structure of the conventional coil bobbin was developed in 1985.
There is one shown in Figures 5 and 6 of No. 9536. In the figure, the terminal of the coil 4 is connected to the coil bobbin 2.
It passed through a notch 9a formed in and was tied to the terminal 3.

However, in such a structure, when winding of the coil 4 is finished and the end of the coil 4 is tied to the terminal 3, it is necessary to align the position of the coil 4 with the position of the notch 9a. Further, the coil 4 after being wound around the terminal 3 is exposed to the outside between the notch 9a and the terminal 3, and is therefore easily cut, resulting in insufficient reliability. The invention of the present application attempts to solve such problems, and its purpose is to provide a coil bobbin that has excellent workability during assembly and is highly reliable.

A first embodiment is shown in FIGS. 1a and 1b. Figure 1a
1 is a perspective view of the coil bobbin, and FIG. 1b is an enlarged plan view of the end portion 3 of the coil bobbin. The coil winding 2 is wound around a coil bobbin consisting of a coil bobbin body 6 and coil bobbin ends 1 formed in the form of walls on both sides of the coil bobbin body 6. Near the outer peripheral end of one coil bobbin end 1, a terminal portion 3 is provided with a coil terminal 4 erected axially outward. As shown in FIG. 1, an L-shaped notch 5 common to both terminal portion 3 and coil bobbin end 1 is provided on the outer circumferential surface, and one surface 5-a constituting this notch 5 is continuous with the outer circumferential surface. It also constitutes a surface that extends in the winding direction of the coil winding. Further, the other surface 5-b constituting the notch 5 is formed to be substantially perpendicular to the outer circumferential surface of the coil bobbin. The terminal treatment of the coil winding in such a coil bobbin is performed as follows. The coil winding 2 whose winding work has been completed is bent by the surface 5-b which moves the tip end downward from the upper side of FIG. 1 along the surface 5-a forming the L-shaped notch 5. Looseness is prevented. Then, the end of the coil winding is passed into the L-shaped notch 5 and wound around the coil terminal 4. A second embodiment is shown in FIGS. 2a and 2b. Figure 2a
2 is a perspective view of the coil bobbin, and FIG. 2b is an enlarged plan view of the end portion 3 of the coil bobbin. In this embodiment, the terminal portion 3 is provided in the direction of the plate surface of the coil bobbin end 1. The shapes of the L-shaped notches 5 include those in which the included angles of the constituent surfaces are obtuse angles (Fig. 3), those in which the included angles are acute angles (Fig. 4), and those in which the included angles are acute angles (Fig. ) can perform the same function. In the coil bobbin configured in this manner, the terminal processing work of the coil winding 2 after the winding work is performed is to wind the coil from the upper side of FIG. If you move the tip of the wire downward, it will bend over surface 5-b, so
Precise positioning is not required, and it is possible to prevent the coil winding from becoming loose during the process of winding the coil terminal around the coil terminal. Furthermore, since the end of the coil winding is placed inside the L-shaped notch 5 and wound around the coil terminal 4, the coil winding 2 is not exposed to the outside, thereby preventing disconnection of the coil winding in subsequent processes and in the state of the finished product. .

The coil bobbin according to the present invention has an L-shaped notch common to both the terminal portion and the outer peripheral surface of the coil bobbin end, and one side of this notch is a surface that extends in the winding direction of the coil winding. The terminal of the coil winding is arranged in the above-mentioned notch, and when the terminal of the coil after winding is tied to the coil terminal, it can be returned in the opposite direction to the winding direction. Since the coil winding can be moved along this plane and bent over other planes, there is no need to precisely align the ends of the coil, resulting in improved work efficiency and ease of automation. Furthermore, since the ends of the coil windings are disposed within the L-shaped grooves, they are not exposed, thereby preventing wire breakage and significantly improving the quality of the product.
