Abstract

(57) [Summary] [Objective] The alternative battery case according to the present invention is used as a method of using a dry battery in place of a button battery of a device using a button battery. [Structure] In order to use a dry battery as an alternative to a button battery, insert a pseudo button battery into a device that uses a button battery, and put out the lead wire connected to the pseudo button battery to the outside of the device.
The external battery can be used by inserting it into an alternative battery case containing the dry battery.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The alternative battery case according to the present invention is used as a method of using a dry battery instead of the button battery of a device using a button battery.

[0002]

[Prior art]

 Conventionally, in a battery-powered device, when the battery is exhausted, the used battery is taken out and a new battery is replenished. This is done regardless of whether the batteries are button batteries or dry batteries. For devices that use rechargeable batteries, the battery of the device can be charged from an outlet. The selection of batteries to be used depends on the weight, size, usage method and required voltage of the equipment. Button batteries are often used in small and lightweight devices. However, as a characteristic of button batteries, when the batteries are exhausted, the dry batteries gradually diminish, making them unusable at once. Also, the usable time is short.

[0003]

[Problems to be solved by the device]

 As described above, since the button battery is exhausted at once, depending on the device, the button battery must be replaced frequently. In this case, the device cannot be used unless a replacement button battery is prepared. Button batteries are often more difficult to obtain than dry batteries, which is inconvenient. It is convenient if the device shows the remaining battery level, but conventional devices do not have a battery level indicator. Therefore, it would be convenient if dry batteries could be used instead of button batteries. Since it is impossible to change the design of various devices, attach a case containing dry batteries to the outside of the device so that power can be supplied to the devices from the dry batteries.

[0004]

[Means for Solving the Problems]

 In the alternative battery case according to the present invention, a dry battery is put in a case wired in an insertion port, and the case is fitted to a flat plate. Stick a tape fastener on the flat plate. On the other hand, after taking out the button battery of the device, insert the pseudo button battery. In the pseudo button battery, a disk-shaped plastic base with a hole in the center is covered with a conductive metal top lid that has a hole aligned with the position of the hole in the plastic base. Stick a conductive metal plate on the bottom of the plastic base. Attach a lead wire to one end of the conductive metal top cover. Also, attach the lead wire to the bottom conductive metal plate through the center hole. Make a hole in the back cover or part of the side of the device and guide the two lead wires to the outside of the device. Insert the lead wire terminal into the outlet of the alternative battery case. Attach a tape fastener to the back of the device and attach it with the flat tape fastener of the alternative battery case to secure it.

[0005]

[Action]

 By using the alternative battery case configured in this way, the device can be carried together with the alternative battery case. Depending on the equipment storage case, the equipment and alternative battery case can be removed and carried around. Since a pseudo button battery is fitted in place of the button battery of the device, power can be supplied from an external dry battery in the same way as the power supply from the button battery.

【Example】

 Examples will be described with reference to the drawings. FIG. 1 is a perspective view of an alternative battery case according to the present invention. A case 1 having a slot 4 in which a dry battery is inserted is fitted to a flat plate 2. A tape fastener 3 is attached to the flat plate 2. The lead wires 9 and 10 are attached to the pseudo button battery 5, and the terminals are inserted into the insertion ports 4 of the case 1.

FIG. 2 is an exploded perspective view of each component. The dry battery 11 is put in the case 1 in which the insertion port 4 is wired, and fitted to the flat plate 2 to which the tape fastener 3 is attached. On the other hand, in the pseudo button battery, a disk-shaped plastic base 6 having a hole in the center is covered with an upper lid 7 of a conductive metal having a hole corresponding to the position of the hole of the plastic base 6. A conductive metal plate 8 is attached to the bottom of the plastic base 6. Attach the lead wire 9 to one end of the upper lid of the conductive metal. Further, the lead wire 10 is attached to the conductive metal plate 8 at the bottom through the central hole.

[0008]

[Advantage of the Invention] By using an alternative battery case, an inexpensive dry battery which is easy to obtain and inexpensive can be used in place of an expensive button battery which is difficult to obtain, and battery usage time is extended. The alternative battery case does not get in the way when using the main unit.
