【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of a fuse puller according to the present invention. In the figure, a fuse puller 10 has a flexible hollow rectangular parallelepiped 11 and a pair of protrusions 12 that protrude inward from both side walls of one end 11 a of the rectangular parallelepiped 11 that face each other.

The tip of one end 11 a of the rectangular parallelepiped 11 serves as a fuse insertion port 10 a when the fuse puller 10 is fitted into the head 2 of the small blade type fuse 1 shown in FIG. 4A. The fuse insertion port 10a is made slightly larger than the fuse head 2 so that the puller 10 can be fitted, and when the fuse puller 10 is fitted, the corner S of each protrusion 12 that abuts the fuse head 2 is It is chamfered. Each protrusion 12 is provided in the vicinity of the fuse insertion port 11a so that it can be engaged with the groove 4 of the fuse head 2 when the fuse puller 10 is fitted into the fuse head 2.

The hollow rectangular parallelepiped 11 has a wall thickness reduced on both side walls having the projection 12 at one end portion (that is, the periphery of the fuse insertion port 10a) 11a, and a fuse pulling direction (that is, A step Y is provided in a direction perpendicular to the center line XX direction of the hollow rectangular parallelepiped 11, and on both side walls thereof, the step Y is provided along the step Y between the step Y and the projection 12 (that is, in the vicinity of the projection 12). That is, a slit 13 is provided as a cutout portion (in the direction perpendicular to the fuse withdrawal direction). Therefore, the flexibility of the both side walls having the projection 12 of the one end 11 a of the hollow rectangular parallelepiped 11 is increased.

In order to attach the fuse puller 10 having such a configuration to the fuse 1, first, the fuse insertion port 10a of the fuse puller 10 is brought into contact with the fuse head 2 shown in FIG. Press toward. Then, each protrusion 12 of the fuse puller 10 is pressed against the side wall of the fuse head 2 and both side walls having the protrusion 12 of the one end 11a of the fuse puller are deformed outward in a curved shape, so that one end of the fuse puller 10 is bent. The portion 11a fits the fuse head 2, and the protrusions 12 of the fuse puller 10 are engaged with the grooves 4 of the fuse 1 so that the fuse puller 10 can be attached to the fuse 1.

It should be noted that, as compared with the case of attaching the fuse puller 10 to the fuse 1 as in the conventional example, the flexibility of both side walls having the protrusion 12 of the one end 11a of the fuse puller 10 is increased. The force that pushes the puller 10 toward the fuse 1 can be reduced, and thus the fuse puller 10 can be easily attached to the fuse 2.

As described above, in the present embodiment, the thickness of both side walls of the fuse puller 10 having the projection 12 of the one end 11a is reduced to provide the stepped portion Y, but the present invention is not limited to this, and the stepped portion is formed as shown in FIG. The wall thickness of the both side walls may be constant without providing the portion. Even in such a case, since the both side walls have the slits 13, the flexibility can be increased as compared with the case of the conventional example. Therefore, compared with the case of the conventional example, when the fuse puller 10 is attached to the fuse 1, the force pressing the fuse puller 10 toward the fuse 1 can be reduced, and thus the fuse puller 10 can be easily attached to the fuse 1. Can be installed.

FIG. 3 shows another embodiment of the fuse puller according to the present invention. In this figure, the embodiment of FIG. 3 differs from the embodiment of FIG. 2 in the following points. That is, as in the case of the embodiment of FIG. 2, the slit 23 is not provided in the direction perpendicular to the drawing direction of the fuse 1, but the slit 23 is formed in the projection 22 of the one end 21 a of the hollow rectangular parallelepiped 21. A notch formed on the both side walls having a predetermined length between the pair of protrusions 22 (that is, in the vicinity of the protrusion 22) in the fuse pulling direction (that is, the center line XX direction of the fuse puller 20) from the fuse insertion port 20a. It is the point where the slit 23 is provided.

The parts other than the above have the same configuration as that of the embodiment of FIG.

In such a configuration, when the fuse insertion port 20 a of the fuse puller 20 is brought into contact with the fuse head 2 and the fuse puller 20 is pressed toward the fuse 1, both side walls are separated as shown in FIG. 3C. Since it is not deformed continuously in a curved shape, is cut by the slit 23 and is bent outward, the flexibility can be increased as compared with the conventional example, and therefore the fuse puller 20 can be easily attached to the fuse head 2. It can be fitted and the fuse puller 20 can be attached to the fuse 1.

In the embodiment shown in FIGS. 1 to 3, two protrusions 12 and 22 are provided on opposite side walls of the end portions 11a and 21a of the rectangular parallelepiped bodies 11 and 21 of the fuse pullers 10 and 20, respectively. , But is not limited to this.
