Abstract

An electric device according to the present invention includes a main body portion of the electric device that is designed to be connected to a battery park. A connecting portion for connecting the battery pack is formed to the main body portion of the electric device. A terminal supporting plate having at least a pair of terminals and for connecting terminals of the battery pack is fixed to the connecting portion. The terminals and are arranged on a front surface side of the terminal supporting plate that is exposed from the connecting portion. An electric material component is arranged on a rear surface side of the terminal supporting plate.

Claims

1. An electric device having a main body portion capable of connecting to a battery pack that has a secondary battery and at least two terminals for transmitting an energy stored in the secondary battery, comprising:

a connecting portion provided on the main body portion for connecting the battery pack; and

a terminal supporting plate fixed to the connecting portion and having at least a pair of terminals for connecting terminals of the battery pack;

wherein

the terminals of the terminal supporting plate are arranged on a front surface side of the terminal supporting plate that is exposed from the connecting portion;

the terminals are embedded into the terminal supporting plate so as to be integrated therewith;

an electric material component is arranged on a rear surface side of the terminal supporting plate; and

the electric material component comprises a tag for prohibiting unauthorized access, a RFID tag, or a fuse.

2. The electric device as defined in claim 1, wherein a recessed portion for receiving the electric material component is formed on the rear surface of the terminal supporting plate, and an opening of the recessed portion is closed with a member, which is disposed over the terminal supporting plate.

3. The electric device as defined in claim 2, wherein the main body portion of the electric device includes a bit, a tubular housing main body portion for accommodating a motor for generating a rotational force to be applied to the bit and a grip portion formed on a lateral side of the housing main body portion and protruding in a radially outward direction therefrom;

wherein the connecting portion for connecting the battery pack is formed at a protruding end of the grip portion, which is formed to the main body portion of the electric device.

4. The electric device as defined in claim 2, wherein the at least a pair of terminals provided to the terminal supporting plate is arranged like a rail.

5. The electric device as defined in claim 1, wherein the main body portion of the electric device includes a bit, a tubular housing main body portion for accommodating a motor for generating a rotational force to be applied to the bit and a grip portion formed on a lateral side of the housing main body portion and protruding in a radially outward direction therefrom;

wherein the connecting portion for connecting the battery pack is formed at a protruding end of the grip portion.

6. The electric device as defined in claim 5, wherein the at least a pair of terminals provided to the terminal supporting plate is arranged like a rail.

7. The electric device as defined in claim 1, wherein the at least a pair of terminals provided to the terminal supporting plate is arranged like a rail.

8. The electric device as defined in claim 1, wherein the at least a pair of terminals provided to the terminal supporting plate is arranged like a rail.

9. An electric device having a main body portion capable of connecting to a battery pack that has a secondary battery comprising:

a connecting portion provided on the main body portion for connecting the battery pack; and

a terminal supporting plate having at least a pair of terminals and fixed to the connecting portion;

wherein

the terminals of the terminal supporting plate are arranged on a front surface side of the terminal supporting plate that is exposed from the connecting portion;

the terminals are embedded into the terminal supporting plate so as to be integrated therewith;

an electric material component is arranged on a rear surface side of the terminal supporting plate; and

the electric material component comprises a tag for prohibiting unauthorized access, a RFID tag, or a fuse.

10. The electric device as defined in claim 9, wherein a recessed portion for receiving the electric material component is formed on the rear surface of the terminal supporting plate, and an opening of the recessed portion is closed with a member, which is disposed over terminal supporting plate.

11. The electric device as defined in claim 9, wherein the main body portion of the electric device includes a bit, a tubular housing main body portion for accommodating a motor for generating a rotational force to be applied to the bit and a grip portion formed on a lateral side of the housing main body portion and protruding in a radially outward direction therefrom.

12. The electric device as defined in claim 11, wherein a connecting portion for connecting the battery pack is formed at a protruding end of the grip portion, which is formed to the main body portion of the electric device.

13. The electric device as defined in claim 9, wherein at least a pair of terminals provided to the terminal supporting plate is arranged like a rail.

14. An electric device having a main body portion capable of connecting to a battery pack that has a secondary battery and at least two terminals for transmitting an energy stored in the secondary battery, comprising:

a connecting portion provided on the main body portion for connecting the battery pack; and

a terminal supporting plate fixed to the connecting portion and having at least a pair of terminals for connecting terminals of the battery pack;

wherein

the terminals of the terminal supporting plate are arranged on a front surface side of the terminal supporting plate that is exposed from the connecting portion;
