Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a power supply box, and more particularly, to a structure of a power supply box that can safely recover a rechargeable battery housed in a main body case.

[0002]

[Prior Art]

 A power supply box used as a means for supplying backup power to an electric device such as a portable video game machine is provided in a main body case composed of a bottom case and a cover case as disclosed in, for example, Japanese Utility Model Laid-Open No. 2-47766. Although it is configured to house the power supply battery, in recent years, rechargeable batteries have been widely used as the power supply battery.

When the power supply box breaks down or has reached the end of its useful life and is to be discarded, due to environmental problems, the rechargeable battery is taken out of the main body case and separately collected for disposal. After removing the cover case from the bottom case, the rechargeable battery was taken out from the bottom case and collected.

[0004]

[Problems to be solved by the device]

 However, the conventional case has a simple structure to attach the cover case so that anyone can collect the rechargeable battery, and when the cover case is removed, both the rechargeable battery and the high-voltage part housed in the bottom case are exposed. It was something to do. In this case, when the power supply cord is connected to the commercial power source, the high voltage part is in a high voltage state, and if the fingertip touches this, there is a risk of receiving an electric shock. In particular, if this kind of power supply box is provided for toys, there is a risk that a child with poor electrical knowledge may unnecessarily disassemble the cover case and damage the high-voltage side, which is complicated in terms of circuitry. There was also a risk of a short circuit or burning accident. Then, this invention aims at providing the power supply box which can collect a rechargeable battery safely.

[0005]

[Means for Solving the Problems]

 To this end, the present invention divides the cover case 3 mounted on the bottom case 2 into a first cover piece 3a for covering the high voltage part 12 and a second cover piece 3b for covering the rechargeable battery 13, and Partition walls 8 and 11 that partition the space between the portion 12 and the rechargeable battery 14 and shield the front surface of the high-voltage portion 12 are provided.

[0006]

[Action]

 In the above configuration, when the rechargeable battery 14 is collected, only the second cover piece 3b is removed from the bottom case 2, and the first cover piece 3a is left attached to the bottom case 2. Then, the electrically dangerous high-voltage portion 12 is completely covered by the first cover piece 3a, and therefore, there is no risk of the fingertip touching the high-voltage portion 12, and the rechargeable battery 14 can be safely recovered.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a power supply box, and FIG. 2 is a side view of the same. The main body of the power supply box 10, which is a main body case 1 made of synthetic resin and having an insulating property, has a substantially box shape and is composed of a bottom case 2 and a cover case 3 which is detachably attached to the bottom case 2. .. Further, the cover case 3 is divided into a first cover piece 3a and a second cover piece 3b, which are detachably attached to the bottom case 2 separately.

On the back surface of the second cover piece 3b, a hook 4 is fixed at its upper end portion with a screw 5 so as to be removable. The hook 4 is attached to a belt of pants or the like. The screw 5 is an ordinary screw such as a plus screw or a minus screw, and can be attached and detached by an ordinary screwdriver. The screw 5 penetrates the screw hole 29 of the cover piece 3b shown in FIG. 4 and is screwed into the boss 26 provided upright on the side portion of the bottom case 2, so that the cover piece 3b and the hook 4 are put together. Assemble to 2. A cord 6 for feeding power to an electric device (not shown) is led out from a joint portion between the bottom case 2 and the cover piece 3b. In FIG. 6, 10 is a plug at the tip of the cord, which is connected to an electric device such as a video game machine.

FIG. 3 is a perspective view with the second cover piece 3b removed, and FIG. 4 is an exploded perspective view. A substantially central portion of the bottom case 2 is partitioned by a partition wall 11, and one side portion of the partition wall 11 accommodates a high voltage portion 12 composed of a transformer and a step-down inverter circuit, and the other side portion thereof is filled. A battery pack 13 is stored. The partition wall 11 may be integrally projected from each of the bottom case 2 or the cover piece 3a, or may be sandwiched between the cover piece 3a and the bottom case 2. The first cover piece 3a is attached to the bottom case 2 so as to cover the high-voltage portion 12 housed in one side of the bottom case 2, and the second cover piece 3b is attached to the other side of the bottom case 2. It is attached to the bottom case 2 so as to cover the stored charging pack 13. As shown in FIG. 3, the rechargeable battery pack 13 is constructed by accommodating four NiCd rechargeable batteries 14 in a bag body 15.

As shown in FIGS. 4 and 6, a wiring board 15 is erected on the back surface of the high voltage section 12. An electric element 16 such as a switching element is wired on the wiring board 15, and the high voltage section 12 is connected to the wiring board 15. The cord 6 and the charging pack 13 are also connected to the wiring board 15 by the lead wires 17 and 18. A connector 21 is provided on the side surface of the bottom case 2. This connector 21 is connected to a commercial power source by a power supply cord (not shown). Reference numeral 22 is a lead wire that connects the connector 21 and the wiring board 15. As shown in FIG. 6, a standing wall 31 is erected between the wiring board 15 and the connector 21. The standing wall 31 prevents the wiring board 15 from falling to the connector 21 side and electrically contacting the connector 21.

As shown in FIGS. 3 and 5, a partition wall 8 is erected on the inner surface on the tip side of the first cover piece 3a, and the partition wall 8 and the partition wall 11 are joined together in an assembled state. Then, the space between the high voltage section 12 and the charging pack 13 is partitioned. In FIG. 5, reference numerals 23, 24, and 25 denote ribs provided upright on the inner side of the bottom case 2 and the second cover piece 3b, and regulate the positional deviation between the high-voltage section 12 and the charging pack 13.

In FIG. 4, bosses 26 and 27 are provided upright inside the bottom case 2 and the cover piece 3 a. These bosses 26 are arranged so as to surround the high voltage part 12 and the charging pack 13, and the bottom case 2 and the cover piece 3a are detachably coupled by inserting a screw 28 into the screw hole 29. This screw 28 has a special head and cannot be removed without using a special screwdriver. By using such a special screw 28, the user can freely remove the cover piece 3a. Therefore, the electrically dangerous high voltage portion 12 is not exposed. Of course, the mounting structure of the cover piece 3a on the side closer to the cover piece 3b does not use the special screw 28, but a hook-like locking body is provided between the cover piece 3a and the bottom case 2, and after locking, If the screw 28 on the side (connector side) is stopped, the cover piece 3a cannot be removed unless the special screw 28 is removed.

In the above configuration, normally, the plug 10 is connected to a video game machine or the like to supply backup power. Further, when the rechargeable battery 14 is discharged, the connector 21 is connected to a commercial power source for charging. The high-voltage unit 12 reduces the commercial power supply voltage during this charging.

When the power supply box 10 is broken or the rechargeable battery 14 reaches the end of its life, the rechargeable battery 14 must be separately collected for the above-mentioned environmental reasons. In this case, as shown in FIG. 3, the screw 5 is reversely rotated to remove only the second cover piece 3b and open only the upper portion of the charging pack 13. Therefore, as shown in the figure, the charging pack 13 is taken out from the bottom case 2, the lead wire 18 is cut with a blade, and the charging pack 13 is collected separately from the main body case 1. When the charging pack 13 is collected, as shown in FIG. 3, the electrically dangerous high-voltage portion 12 is shielded by the partition walls 8 and 11 inside the cover piece 3a. Can be collected.
