る。 Some magnetic heads have two independent coils and form an intermediate connection by connecting the coils in series. Figure 1 is an exploded perspective view of a conventional magnetic head, the magnetic head in Figure 2 is an improved version of the one shown in Figure 1, and the magnetic head shown in Figure 3 is an exploded version of the improved version of Figure 2. FIG. In FIG. 1, coils 3 and 4 are wound around cores 1 and 2 made of high magnetic permeability material, respectively.
The coil 3 has coil end portions 3a and 3b, and the coil 4 has coil end portions 4a and 4b, and an intermediate connection portion 5 is formed by connecting the coil end portions 3b and 4a. Next, the holding part 6 made of an electrical insulator is attached to two terminals 7 made of an electric conductor (the holding part 6
(which is bent inside) is held, and the connecting portions 7a and 7b are exposed on the upper surface thereof. Then, the coil end portion 3a is connected to the connecting portion 7a by soldering or the like, and the coil end portion 4b is similarly connected to the connecting portion 7b. Such a magnetic head can be easily moved because the intermediate connection portion 5 is not fixed. Therefore, if the intermediate connection portion 5 comes into contact with, for example, the connection portion 7a or 7b, unexpected troubles may occur. In order to eliminate this drawback, the configuration shown in FIG. 2 can be adopted (in addition, the same numbers are attached to the same members in FIGS. 2 and 3). In addition to the terminal 7, two terminals 8 made of a conductor are provided on the holding part 6 shown in FIG. . Then, the coil ends 3a, 3b, 4a, 4b are connected to the connecting portion 7, respectively.
Connect to a, 8a, 8b, 7b by soldering etc.
The two terminals 8 are bent to partially contact each other, and the connecting portion 9 is connected by soldering or the like. In other words, the coil ends 3b, 4a are connected to the connecting parts 8a, 8b.
It is fixed at However, in the configuration shown in FIG. 2, two terminals 8 are provided, and the terminals 8 are bent and soldered, so the number of parts and steps are large. In order to improve this drawback, as shown in FIG. It is also conceivable to connect the coil end portions 3b and 4a to the portion 10 by soldering or the like. However, the parts provided on the upper surface of the holding part 6, that is, the connecting part 10, and the connecting part 1
0 on the upper surface of the holding part 6 is required.
本考案の磁気ヘツドは第１図〜第３図の欠点を
除去し、第１図に示した構成よりも部品数を増加

2 are wound with coils 13 and 14, respectively. The coil 13 has coil ends 13a, 13b, and the coil 14 has coil ends 14a, 14b.
However, an intermediate connection portion 15 is formed by connecting the coil end portions 13b and 14a. Next, a holding part 16 made of an electrical insulator made of resin such as phenol mixed with glass powder holds two terminals 17 made of a conductor (bent inside the holding part 16), Connecting parts 17a, 17b on the top surface
expose. Furthermore, the upper surface of the holding part 16 is made of the same material as the holding part 16 and has a shape capable of fixing the intermediate connection part 15, for example, a protruding part 16a. Since this protruding part 16a is molded at the same time as the holding part 16 is made, there is no special process for providing the protruding part 16a. and coil end 1
3a is connected to the connecting portion 17a by soldering or the like, and the coil end portion 14b is similarly connected to the connecting portion 17b. Next, the intermediate connection portion 15 is wound and fixed around the protrusion 16a (after the coil ends 13b and 14a are wound around the protrusion 16a, the coil ends are soldered to form the intermediate connection portion 15). is also good).
