[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dry battery adapter.

[0002]

[Prior art]

 Conventionally, by attaching an adapter for increasing the outer diameter to a dry battery with a small outer diameter, it is possible to use a dry battery with a small outer diameter for equipment that uses a dry battery with a large outer diameter. Various adapters have been devised.

An example of a conventional outer diameter conversion adapter will be described below. 3 and 4 are cross-sectional views of a dry battery conversion adapter in a conventional example. 1 is an adapter whose outer diameter is the same as AA batteries and whose inner diameter is the same size as AA dry batteries. 2 is an adapter whose outer diameter is the same as AA batteries and whose inner diameter is the same size as AA dry batteries. 3 is AA. Dry battery, 4 is an electrode terminal, and 5 is a C-size dry battery. Here, by storing the AA dry cell in the adapter 1, and by storing the adapter 2 in the adapter 1 and the AA dry cell in the adapter 2, it becomes possible to use equipment that uses the AA battery. You will be able to use AA batteries or AA batteries.

[0004]

[Problems to be solved by the device]

 However, the above-mentioned conventional configuration has a problem that even if an attempt is made to use a dry battery having a large outer diameter in a device designed to use a dry battery having a small outer diameter, it cannot be used.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a battery dummy having an outer diameter equal to that of a AAA battery and a length that can expand and contract from AA batteries to AA batteries, an external power source, a battery dummy and an external battery. We will provide a dry battery adapter consisting of a cable for connecting the power supply.

[0006]

[Action]

 With the above-described configuration, the present invention attaches a battery dummy to a device designed to use a specific dry battery from AA dry battery to AA dry battery and uses a dry battery or an outlet as an external power source to supply power. Since it can be supplied, the equipment can be operated in an emergency.

【Example】

 1 is a sectional view of a battery dummy of a dry battery adapter according to an embodiment of the present invention, and FIG. 2 is a block diagram of the dry battery adapter.

Reference numeral 10 denotes a battery dummy having a structure in which the outer diameter is equal to that of the AAA dry cell and the length is expandable from the AA dry cell to the AA dry cell, and 20 is an external power source for generating a voltage of 1.5V. Although various forms such as an AC adapter and a dry battery can be considered as an external power source, here, it is assumed that the dry battery box 21 has a single dry battery 22 and a positive power source terminal 23 and a negative power source terminal 24 at both ends. To do.

The battery dummy 10 has a structure in which the resin-molded convex structure 11 and the resin-molded concave structure 12 are integrated by superimposing the convex and concave portions. A spring 17 that generates a force in the direction of extending the length of the battery dummy is inserted between the 1 and the concave structure 12. The positive power source terminal 13 is adhered to the flat surface of the convex structure 11 and the convex structure locking 15 for preventing the convex structure 11 and the concave structure 12 from being easily separated at the tip of the convex portion. There is.

Further, the negative power source terminal 14 is adhered to the flat surface of the concave structure 12 and the concave structure locking 1 for preventing the convex structure 11 and the concave structure 12 from being easily separated at the tip of the concave part. There is 6. Reference numeral 18 is a cable for connecting the electrode terminal of the battery dummy 10 and the electrode terminal of the external power supply.

When the battery adapter configured as described above is attached to a device designed to use a battery, first the both ends of the battery dummy 10 are sandwiched by fingers to shorten the length, and the dry battery box of the device is removed. The battery dummy 10 is mounted so that the positive electrode terminal of the battery dummy 10 contacts the positive electrode side and the negative electrode terminal of the battery dummy 10 contacts the negative electrode side.

With this, the external power source 20, that is, the electrode terminal of the AA battery is connected to the electrode terminal of the device, and the power source can be supplied.

[0013]

[Effect of device]

 As described above, according to the present invention, a battery dummy is attached to a device designed to use a specific dry battery from AA dry battery to AA dry battery, and a dry battery or an outlet is used as an external power source. Since it can supply power, it has the effect of being able to operate the device in an emergency, which is extremely effective in practice.
