[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the shape and structure of a cap with a base for a toroidal coil.

[0002]

2. Description of the Related Art FIG. 4 is a perspective view of a completed toroidal coil using a conventional cap with a base. That is, the toroidal coil 9 is attached to the cap 5 with the base, and the terminal 4 of the toroidal coil 9 is passed through the terminal fixing hole 8 to melt the base and is fixed to the terminal fixing hole 8.
FIG. 5 is a perspective view showing a state in which a terminal of a toroidal coil is fixed to a conventional base. Conventionally, the structure of this type of base-equipped cap 5 is such that a terminal fixing hole 8 of the base-equipped cap 5 has a keyhole shape as shown in FIG. The terminal was fixed by performing heat treatment using the method described above. Further, the heat treatment has a drawback that the processing is very difficult because a part of the resin of the base for mounting the toroidal coil is collected and fixed in the terminal fixing holes.

[0003]

According to the present invention, in order to eliminate these drawbacks, a terminal with a cap with a base is provided with a holder fixing recess or hole near the terminal fixing hole in the base with a cap. After the terminal is passed through the terminal fixing hole by using a U-shaped holder having the claw, the terminal is fixed by the holder so as to wrap the terminal fixing hole and the terminal. That is, an object of the present invention is to provide a cap with a base for a toroidal coil, in which the terminal is fixed to the holder by a holder so that a heat treatment step for fixing the terminal can be omitted, and the terminal can be easily fixed.

[0004]

That is, the present invention relates to a structure of a cap with a base for a toroidal coil used for a toroidal coil, wherein a holder is provided near a keyhole-shaped terminal fixing hole for fixing the terminal through the terminal of the toroidal coil. A fixing recess or hole is provided, the terminal of the toroidal coil is passed through the terminal fixing hole, and the terminal of the toroidal coil is fixed by a U-shaped holder having claws sandwiching the holder fixing recess or hole from above and below. This is a cap structure with a base for a toroidal coil, which is characterized in that it has a structure to be made.

[0005]

According to the present invention, a cap with a base is provided with a concave portion or a hole for fixing a holder, and a U-shaped holder having a claw is used to pass a terminal of a toroidal coil through a hole for fixing a terminal and fix the terminal with the holder. The structure of the holder is such that the terminal is fixed by the holder so as to surround the hole for fixing the terminal. That is, when fixing the terminal of the toroidal coil with the base and the holder, a U-shaped holder having four claws so as to press down the holder fixing concave portion or the hole portion from above and below is a keyhole-shaped arc-shaped. In addition, a holder fixing hole corresponding to the terminal fixing hole which is a keyhole-shaped arc-shaped space of the holder is provided on the base side. By doing so, the terminal is passed through the terminal fixing hole, which is the space of the base, and the terminal is fixed with the holder, so the heat treatment step at the time of fixing the terminal can be omitted, and the cap structure with a base for toroidal coil that makes it easy to fix the terminal is provided. Can be provided.

[0006]

FIG. 1 is an example in which the structures of a base and a holder according to the present invention are clarified. FIG. 2 is an example of assembling the toroidal coil using the base and the holder of the present invention. FIG. 3 shows an embodiment of a completed toroidal coil using the base and the holder according to the present invention. In FIG. 1, a cap 1 for mounting a toroidal coil has a terminal fixing hole 8 for fixing a terminal of the toroidal coil. The terminal fixing hole 8 generally has a keyhole shape or a U-shape. In FIG. 1, two holder fixing recesses or holes 3 are provided near the terminal fixing holes, and four holder claws 7 are provided in FIG. 1 so as to sandwich the holder fixing recess or hole. A U-shaped holder 2 is provided. As shown in FIG. 2, the holder claw 7 is inserted into the holder fixing recess or hole 3 provided on the base-attached cap 1 on which the toroidal coil 9 is mounted. The terminal 4 of the toroidal coil 9 is
Envelop. In FIG. 2, the terminal of the toroidal coil is to be fixed by two holders from both sides through the terminal fixing holes so as to sandwich the holder fixing concave portion or the hole 3 of the cap with base. FIG. 3 shows that the claws of the holder are fitted into the holder fixing recesses or holes provided in the base-attached cap 1 on which the toroidal coil 9 is mounted, so that the terminals 4 of the toroidal coil passed through the terminal fixing holes are pressed. This is a completed toroidal coil with base cap, showing that the holder has been set. Fixing the terminal of the conventional toroidal coil is done by passing the terminal through the terminal fixing hole, heating the base with a soldering iron, melting it and fixing the terminal fixing hole, and fixing it. It took a lot of time to melt the base and collect the resin from the base and plug the holes for fixing the terminals. Eliminating these man-hours makes the work easier, and according to the present invention, the terminal fixing process has been performed by heat treatment. Is also simplified. Further, by changing the diameter of the space portion of the holder, it is possible to solve the problem of fixing due to a difference in the used wire diameter or the like.

[0007]

As described above, according to the present invention, it is possible to provide a cap with a base having advantages of simplifying and shortening the terminal fixing of the coil and preventing a decrease in yield due to a defect in heat treatment.
