BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery device containing, for example, one or more lithium primary batteries or the like, and more particularly to solving the problems at the time of discarding these batteries.

[0002]

2. Description of the Related Art In recent years, primary batteries such as alkaline manganese batteries and lithium batteries have been used in portable electric devices such as cameras and wireless devices, or in memory backup applications such as computers, in single or multiple pieces. A battery that is made up of individual batteries is used.

[0003] In the case of a primary battery, it is necessary to replace the battery when the battery capacity is exhausted. When the current of the used equipment is small, the capacity of the battery is used efficiently, and the used battery which is almost completely discharged is replaced with a new battery.

[0004] However, when the current used by the device is large relative to the capacity of the battery, or when the set voltage (discharge inhibition voltage) of the device is high, the battery is replaced with a certain amount of battery capacity remaining. May be done.

Further, when the camera is used intensively for a relatively short period of time like a camera, that is, in the case of travel or the like, the battery may be quickly replaced prior to use. In such a case, the normally usable battery is simply discarded.

By the way, the self-discharge of a primary battery has been reduced by recent technical innovations. In particular, the self-discharge rate of a lithium battery is extremely small, and the battery remains alive for a long period of time even if left unattended. become.

[0007] The battery having such a capacity is discarded,
When the conductive material in the other waste is connected between both terminals, the battery is short-circuited, causing heat generation and liquid leakage.

Further, when a large number of batteries are discarded and a battery having a remaining capacity and a fully discharged battery are connected to each other and short-circuited or discharged, the fully discharged battery is forcibly discharged. Discharge occurs, resulting in a so-called overdischarge state. When the battery is over-discharged, the normal discharge reaction does not occur in the battery, the electrolyte is decomposed, flammable gas is generated, and the battery is short-circuited or the heat generated when over-discharged causes a dangerous condition. Become.

Further, when the battery is discarded in water,
Water is decomposed by the electric energy of the battery, generating hydrogen,
Not preferred for safety.

[0010]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems.
Suppress unfavorable situations in safety, such as the conductive state between the terminals of the battery and the battery generates heat, leaks, or generates flammable gas inside the battery due to overdischarge. Things. As a result, a battery device that does not cause a problem in safety after disposal is proposed.

[0011]

The battery device according to the present invention comprises a case accommodating at least one battery and an insulating member.
In the battery device, the case includes the first recess and the first recess.
Two recesses, and the first recess has one end of the battery.
At least one external terminal electrically connected to the terminal
And the external terminal is located in the second recess.
Is not located, and the insulating member is provided in the first recess and
It can be installed in any of the second recesses.
You.

[0012]

[0013]

According to the present invention, at least one external terminal electrically connected to one terminal of the battery located in the first recess is connected to both the first recess and the second recess. Can be installed
By covering with an insulating member , the external terminals are isolated and isolated. As a result, even when the battery device is discarded, the above-described problem does not occur.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. First Embodiment FIG. 1 is a perspective view of a battery device according to the present invention. here,
FIG. 1A is an overall perspective view when a battery device is loaded in a device. B is an exploded perspective view of the insulating member 1 and the battery case 3. C is an overall perspective view showing a state where the battery device is discarded.

First, as shown in A, the external terminal 2 is not insulated and isolated by an insulating member 1 made of synthetic resin, and the insulating member 1 is attached to the bottom 4 of the battery case 3 opposite to the external terminal 2. Is attached, and the battery device is loaded into the device. The external terminal 2 is electrically connected to one terminal of a battery housed in a battery case 3, and a plurality of lithium primary batteries (two in this embodiment) are provided in the battery case. )
They are housed and connected in series. In this state, the electric energy of the battery can be extracted from the battery device through the external terminal 2.

Next, as shown in B, the insulating member 1 and the battery case 3 in which a battery (not shown) is housed,
The battery device shown in A is taken out of the used device and the insulating member 1 is removed from the battery case 3 because it is configured to be able to be separated. The battery case 3 is made of a two-piece case made of a synthetic resin.

As a result, as shown in FIG.
The battery device can be disposed of by mounting the insulating member 1 on the upper part 5 of the battery so as to insulate and isolate the external terminal 2. Second Embodiment FIG. 2 is a perspective view of a battery device according to another embodiment of the present invention. Here, A is an overall perspective view when the battery device is loaded in the device, B is an exploded perspective view of the insulating member 11 and the battery case 13, and C is an overall perspective view showing a state where the battery device is discarded.

The second embodiment differs from the first embodiment in that the insulating member 11 is mounted on the side surface of the battery case 13 and the external terminal 12 is provided on the upper end surface of the battery case 13. Is a point. Here, the insulating member 11 used
May be a plate-shaped member made of synthetic resin,
Further, it may be a tape-shaped member.

The external terminal 12 is connected to a battery case 13
It is shared with one terminal of the housed battery within, in this state, that looks like taken out electrical energy of the battery from the battery device.

As described above, according to the battery device of the present invention,
If, one electrode terminal and electrically connected to the external terminals of the batteries, Ri by the fact covering with the insulating member, the outer portion terminals, insulation, would be isolated, as a result, leaving the capacity When a battery device is disposed of, the short circuit phenomenon between terminals can be suppressed, an overdischarged state, a dangerous state due to heat, etc. can be avoided, and a battery device with excellent safety can be provided. The target value is extremely large.
