Description

[Detailed Description of the Invention] The present invention relates to a portable power supply device that includes a chargeable/dischargeable battery and a charge/discharge function such as a charge/discharge control circuit within a main body case.

Generally, this type of portable power supply unit is equipped with a spare fuse so that it can be replaced immediately if the fuse burns out, but in the past, this spare fuse was provided with specifications and instruction manuals that were separate from the equipment. A spare fuse can be inserted into the main body by keeping it in a bag or by removing the lid for taking out the battery etc. using a tool. However, in the former case, it is necessary to carry a spare fuse in case the fuse should break, and there is a fear that it will be lost in this case. In the latter case, if the fuse blows out, the battery removal cover must be removed using a tool and replaced.Furthermore, in this case, a spare fuse is stored inside the main body, so whether there is a spare fuse or not. The disadvantage was that it was difficult to confirm.

SUMMARY OF THE PRESENT DISCLOSURE In view of the above-mentioned drawbacks of the conventional technology, the present invention has an object to provide a structure that makes it easy to check whether a spare fuse is present and also allows the spare fuse to be easily replaced without the use of tools.

The basic structure of the present invention to achieve the above object is that a storage section for storing a spare fuse is provided outside the main body case, and the spare fuse is held by a cap made of an elastic material. The cap is detachably attached to the storage section.

With the above configuration of the present invention, the spare fuse storage section is located outside the main body case, so it is easy to check the presence or absence of the spare fuse, and when replacing the spare fuse, it is possible to Since the body cap can be removed without using any tools by simply pulling it out against the elastic force, the replacement work is extremely easy, and it also prevents the loss of spare fuses. This configuration has practical effects.

An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 to 5, reference numeral 1 denotes a main body case, and this main body case 1 is made of synthetic resin and has a hollow cylindrical shape with both ends open. 2
3 is a handle integrally molded on the upper part of the main body case 1;
2 is a front cover that is fitted to cover the front opening of the main case 1 and is detachably attached by screwing in screws 3' from both sides. As shown, a charging terminal 4, a charging indicator lamp 5, an output socket 6, a capacity meter 7, a fuse holder 8, etc. are provided. In addition,
Although the wiring cord in the figure is omitted, the connection to the rechargeable and dischargeable battery 9 serving as the power source is made by a flat cord via a dedicated connector.
Reference numeral 10 denotes a back cover that is fitted to cover the opening on the rear side of the main body case 1 and is detachably attached with a plurality of screws 11 as shown in FIGS. 3 and 4. As shown in FIG. 4, the battery 9 is stored through the rear opening of the main body case 1 with the back cover 10 removed.

Reference numeral 12 denotes a storage section formed integrally with the main body case 1 at the rear of the handle 2, and this storage section 12 stores a spare fuse 13. Reference numeral 14 denotes a bottomed cylindrical cap made of an elastic material such as synthetic resin.
While holding it, it is removably attached to the storage section 12 as shown in FIG.

FIG. 6 shows an embodiment in which a hat cap 14 holding the spare fuse 13 is detachably attached to a storage portion 12 formed to protrude inward from the outer surface of the main body case 1.

In the above configuration, since the cap 14 is made of an elastic material, it is easy to hold the spare fuse 13, and since the storage portion 12 and the cap 14 have appropriate elasticity, the cap 14 is easily damaged by vibrations, etc. It will not fall off and the hat body cap 14
can be easily attached to and removed from the storage section 12. Further, the storage section 12 is provided so that the cap 14 does not protrude beyond the outermost side of the main body case 1 when the cap 14 is attached to the storage section 12. This can prevent it from coming into contact with other objects and easily falling off.

As described above, according to the present invention, since the storage section for storing the spare fuse is provided outside the main body case, it is easy to check whether there is a spare fuse.
In addition, the spare fuse is held by a cap made of an elastic material, and this cap is detachably attached to the storage section, so when replacing the spare fuse, the cap made of an elastic material is used. It can be removed without using any tools by simply pulling it out against the elastic force, making replacement work extremely easy, and also preventing the loss of spare fuses. .
