Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a blade-type fuse ejector mounted in a fuse box interposed in an electric wiring of an automobile.

[Conventional technology]

As shown in FIG. 5, the blade-type fuse a mounted on the fuse box of the automobile has two-legged terminals b, b.
A fusing part (not shown) is provided therebetween, and a synthetic resin coating c is provided on the fusing part, and a locking head d is formed on the coating c.

The ejector e for the fuse a connects the pair of rigid arms g, g having the engagement protrusions f, f formed on the inner side of the tip with the elastic connecting piece h at the intermediate portion, and presses the operating portions i, i. By doing so, the engaging projections f are separated from each other and engaged with the locking head d, and the fuse a is pulled out in this state.

By the way, when a blown fuse is taken out from the fuse box with a blower, a new fuse must be immediately inserted, and a storage place for this new fuse must be provided nearby.

Conventionally, the fuse and the ejector are stored together in the cover of the fuse box, but a separate mounting space is required.

[Problems to be solved by the device]

On the other hand, the present invention provides a compact fuse removing tool that can store a spare fuse, and can store the fuse together with the fuse removing tool in a small space.

[Means for Solving the Problems]

In order to achieve the above object, in the present invention, a spare fuse accommodating chamber made of a synthetic resin material is formed so as to penetrate the cylinder, and a fuse is pulled out to one opening end side of a flexible side wall forming the spare fuse accommodating chamber. And a fuse attaching / detaching projection is formed in the middle portion near the other opening end.

〔Example〕

In FIG. 1, A is a fuse removing tool, a is a blade type fuse, and B is a fuse box.

The fuse removing tool A is formed as a flat rectangular cylinder made of a synthetic resin material and has a preliminary fuse accommodating chamber 1 penetrating therethrough.

Two fuse pull-out locking projections 3, 3 are provided on one opening end side P of the inner surface of the wide flexible side wall 2 forming the spare fuse accommodating chamber 1, and the inside of the other opening end q is provided. One fuse attachment / detachment locking projection 4 is provided in a protruding manner in the middle portion which is close to.

The pulling-out locking projection 3 has a tapered guide surface 3a on the opening end P side and has a locking step portion 3b inside. On the other hand,
The attachment / detachment locking projection 4 has tapered guide surfaces 4a and 4b on the opening end q side and the inside, respectively.

In the above structure, as shown in FIG. 3, the spare fuse a ′ is inserted into the fuse removing tool A from the opening end q with the locking head d first, and the side wall 2 is flexibly deformed. It rides over the attachment / detachment locking projection 4 and abuts against and is supported by the extraction locking projection 3.

And when using it as a fuse remover,
As shown in the figure, when the open end P side of the fuse removing tool A is brought into contact with and pressed by the blade type fuse a of the fuse box B, the locking head d is attached / detached via the tapered guide surface 3a. 4, the spare fuse a ′ built therein is pushed out.

When the fuse pulling tool A is pulled in this state, the locking step 3b of the pulling locking projection 3 engages with the locking head d of the fuse a and pulls it out. Then, the pushed-out spare fuse a ′ is inserted into the fuse box B in place of the pulled-out fuse a, and the pulled-out fuse a is inserted into the fuse removing tool A.
Is taken out from the open end q of.

[Effect of device]

As described above, the present invention forms a spare fuse accommodating chamber that is made of a synthetic resin material and penetrates into the cylindrical body, and has a fuse pull-out locking protrusion on one opening end side of the flexible side wall forming the spare fuse accommodating chamber. Since it is formed and the fuse attaching / detaching engaging projection is formed in the intermediate portion near the other opening end, the spare fuse can be built in while making the fuse removing tool compact.
