Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fuse puller holding structure that allows a fuse puller used for pulling out a fuse mounted in a fuse box to be pulled out from the fuse box without rattling and can be easily attached and detached.
[0002]
[Prior art]
Conventionally, for example, a fuse is interposed in the middle of an electric circuit so that an excessive current does not flow through an electric device mounted on an automobile, for example. Although this fuse is stored in a fuse box, in recent years, as a large number of electric devices are mounted on automobiles, the size of the fuse box tends to increase gradually. Therefore, in order to allow a large number of fuses to be placed in close contact with each other in the fuse box, a fuse having the shape shown in FIG. 8 is widely used.
[0003]
The fuse 1 shown in FIG. 8 is a cover 2 made of an insulating resin that covers a terminal 2 formed by integrally punching a conductive metal plate, and a fracture portion that melts and breaks when an excessive current flows through the terminal 2. 3. As a result, this type of fuse 1 can be made much thinner than a conventional cylindrical fuse and can be stored in a very close state in the fuse box.
However, since this type of fuse 1 has a small thickness, it is not easy to pull out the fuse 1 from the fuse box by sandwiching the fuse 1 with a fingertip.
[0004]
Therefore, a fuse puller is used to pull out this type of fuse 1 from the fuse box. This fuse puller is a jig that is generally injection-molded integrally from an insulating resin material, and is always held in a fuse box so that it can be used when replacing a fuse.
[0005]
When holding such a fuse puller in the fuse box, the fuse puller must be held so that it can be easily attached and detached without rattling. Therefore, various types of fuse pullers have been proposed. In Japanese Patent Application Laid-Open No. 8-315715, as shown in FIG. 9, one end 5 of the fuse puller 4 is held so as to be lifted from the mounting surface 6. An improved fuse puller holding structure is described so that the fuse puller 4 can be easily removed.
[0006]
[Problems to be solved by the invention]
However, in the fuse puller holding structure described in JP-A-8-315715 described above, the fuse puller can be easily removed from the fuse box, but between the one end 5 of the fuse puller 4 and the mounting surface 6. When the gap S is provided, another electric wire may be caught in the gap S and the fuse puller 4 may be dropped. Further, since the fuse puller 4 is not structured to hold the entire structure, the fuse puller 4 cannot be securely held, and there is a concern that rattling may occur.
[0007]
SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described problems of the prior art, and to provide a fuse puller holding structure that can easily hold and remove a fuse puller without rattling. .
[0008]

At the same time, since the pair of clamping parts of the fuse puller is clamped in the vertical direction by the lifting prevention part and the vertical clamping part, the fuse puller can be securely held without rattling in the vertical direction on the mounting surface. it can.
Furthermore, since the gripping part connected to the rear end side of the pair of clamping parts of the fuse puller engages with the gripping part side fixing part standing on the mounting surface, the fuse puller can be held more reliably. it can.
[0012]
On the other hand, when removing the fuse puller, the pair of holding parts are separated from each other by pinching the pair of gripping parts with fingers, and the engagement between the locking claw and the locking claw engaging part is released. The puller is displaced backward in the attaching / detaching direction. Next, when the gripping part is lifted away from the mounting surface, the lower part of the tip of the pair of clamping parts enters the receiving recess, so that the fuse puller can be easily removed from the gap between the lifting prevention part and the mounting surface. Can do.
[0013]
