Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a fuse box cover, and more particularly to a fuse box cover in which a fuse removal jig is provided on the side wall of the cover body to allow the fuse to be inserted and pulled out.

[Conventional technology]

Generally, regarding a fuse box cover in which a fuse removal jig is provided on the cover body, there is a device such as that described in, for example, Japanese Utility Model Application Publication No. 56-31452.

In the above invention, as shown in FIGS. 8 to 11, the fitting protrusion 23 for attaching the cover body 21 to the fuse box 22 is also used as a fuse removal jig, and the tip of the fitting protrusion 23 is The fuse head 4A is engaged with the formed T-shaped groove 24 to pull out the fuse 4.

[The problem that the idea aims to solve]

However, as described above, since the locking mechanism of the cover main body 21 and the fuse removal jig are used, the shape is inappropriate as a lock, and there is a problem that the cover main body 21 cannot be mounted reliably. Further, there is a problem that the fuse extraction jig may be damaged due to excessive stress when the fuse is pulled out, and if the fuse extraction jig is damaged, the locking mechanism of the cover body 21 becomes unusable.

Therefore, the present invention solves the problems of the above-mentioned conventional technology, separates the locking mechanism of the cover body and the fuse extraction jig, forms the fuse extraction jig on the side wall of the cover body, and stores a spare part inside the fuse extraction jig. To provide a fuse box cover capable of storing a fuse.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a fuse box that includes a fuse box into which a fuse is inserted and a cover body that is detachably formed on the fuse box via a locking mechanism. A fixed hook is formed on the wall surface, a movable hook is provided facing the fixed hook, and a fuse storage chamber is formed between the fixed hook and the movable hook.

〔Example〕

Hereinafter, embodiments of the fuse box cover according to the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 indicates a box-shaped cover body, and this cover body 1 is adapted to cover the upper surface 2A of the fuse box 2. A plurality of fuse insertion openings 3 are arranged in parallel on the upper surface 2A of the fuse box, and a plate-type fuse 4 is inserted into the fuse insertion opening 3. Further, a plurality of hook-shaped cover locks 5 are provided protruding from the periphery of the upper surface 2A of the fuse box.

On the other hand, on the inner surface of the lower end of the side wall of the cover body 1,
As shown in FIG. 2, a fitting protrusion 6 is formed at a position corresponding to the cover lock 5, and when this protrusion 6 and the cover lock 5 engage, the cover body 1 is securely attached to the fuse box 2. It is becoming more and more common.

Moreover, on the outer surface of one side wall 1A of the cover main body 1,
As shown in FIGS. 1 and 4, a pair of brackets 7, 7 are integrally molded at a predetermined interval, and the upper ends of the brackets 7, 7 are flush with the upper surface 1B of the cover body 1. It is also closed by an integrally molded eave portion 8. Further, at the lower end of the outer surface of the side wall 1A between the brackets 7, 7, a third
As shown in the figure, an engaging protrusion 9 is formed, and the side wall between the brackets 7 constitutes a fixing hook 10 as a whole.

Moreover, between the brackets 7, 7, there are shown in FIG.
As shown in FIGS. 3 and 4, a substantially rectangular movable hook 11 facing the fixed hook 10 is provided. This movable hook 11 has a rotating shaft 12 that is integrated with the movable hook 11 and is attached to the brackets 7, 7.
It is rotatably supported by being supported in the shaft bearing holes 13, 13, and has an engaging protrusion 1 corresponding to the engaging protrusion 9 of the fixing hook 10 at its lower end.
4 is formed. Further, an operating portion 11A is formed at the upper end of the movable hook 11 and is bent outward, and by pressing the operating portion 11A, the movable hook 11 is rotated upward around the rotation axis 12. The movable hook does not come into contact with the eaves part 8 on the fixed hook 10 side when the movable hook is moved. The movable hook 11 is always urged toward the fixed hook 10 by a wire-wound spring 15 whose one end is fixed to the movable hook and whose other end is in contact with the eaves 8 on the fixed hook 10 side. Therefore, the fixed hook 10 and the movable hook 1
1 constitutes a fuse extraction jig 16 that is separate from the locking mechanism of the cover body 1. When using this fuse extracting jig 16, press the operation part 11A to rotate the movable hook 11 upward, open the mouth of the jig 16, and then open the fixed hook as shown in FIG. Simply insert the head 4A of the fuse 4 between the movable hook 10 and the movable hook 11 and pull it out. In addition, when the fuse removal jig 16 is not used, that is, the cover body 1 is removed from the fuse box 2.
In normal use, the wire-wound spring 15
Since the mouth of the jig 16 is always closed due to the spring force, the brackets 7, 7, the eaves part 8, and the fixing hook 10
A fuse storage chamber 17 is formed surrounded by a movable hook 11, and can store a spare fuse 4 as shown in FIG.

FIG. 7 shows another embodiment of the fuse box cover according to the present invention. In this embodiment, a separate movable hook is not incorporated into the cover body, but a fixed hook 10 and a movable hook 11' are attached to the cover body. It is integrally molded with. Even in this manner, the fuse removal jig and the fuse storage chamber can be constructed, and furthermore, by integrally molding, the number of parts can be reduced.

[Effect of idea]

As is clear from the above explanation, in the present invention, the locking mechanism of the cover body and the fuse extraction jig are formed separately, and the fuse extraction jig is combined with a fixing hook.
This fixed hook and a movable hook facing each other form a fuse storage chamber between the fixed hook and the movable hook, so even if the fuse extraction jig is damaged due to the stress of pulling out the fuse, the cover body can be easily removed from the fuse box. The cover can be reliably attached to the cover body, and can fulfill its original function as a cover. In addition, a spare fuse for repair can be stored inside the fuse removal jig that is formed integrally with the cover body, making it possible to prevent the loss of spare fuses, which are small parts, and to easily organize them. Furthermore, since there is no need to provide a separate spare fuse box, space can be saved.
