There were various problems such as being inconvenient and (1) not achieving sufficient effects in terms of airtightness and waterproofness.

Furthermore, since the battery cannot be securely fixed to the device, the contact spring of the device may be deformed due to the weight of the battery, or the battery may come off unexpectedly due to small vibrations when replacing the battery. Due to these, there was a problem that the electrodes of the battery and the contact spring of the device were not in contact with each other. Such problems are particularly problematic in data storage devices such as electronic notebooks. This is because in a data storage device, when the electrode of the battery and the contact spring of the device come out of contact, a huge amount of important data is instantly erased.

The present invention has been made with attention to the above-mentioned problems, and its purpose is to provide a technology that can reduce the cost of devices that carry batteries and facilitate battery replacement of the devices. .

Another object of the present invention is to provide a technique that can prevent the problem of non-contact between the battery electrode and the device contact spring due to deformation of the device contact spring or vibration during battery replacement. There is a particular thing.

Another object of the present invention is to provide a technique that can improve the airtightness and waterproofness of a battery attachment part of a device.

The above and other objects and novel features of the present invention will become apparent from the description of the specification and the accompanying drawings.

[Means to solve the problem]

A brief overview of typical inventions disclosed in this application is as follows.

That is, the invention according to claim 1 provides a battery structure in which a fixing means for fixing the battery body to a battery mounting portion of a predetermined device is formed in the battery body itself.

A third aspect of the present invention provides a battery structure in which a sealing member is provided on at least a portion of the battery main body that comes into contact with the battery mounting portion.

According to the invention described in claim 1 above, the battery itself can be directly fixed to the device. That is, since there is no need for a back cover for fixing the battery to the device, the number of parts in the device can be reduced accordingly, and there is no need to remove and attach the back cover when replacing the battery. Furthermore, since the battery can be securely fixed to the device, the contact spring of the device will not be deformed due to the weight of the battery, and the battery will not come off unexpectedly due to vibration or the like when replacing the battery.

According to the third aspect of the present invention, when the battery is attached to the battery attachment part of a device, the sealing member can improve the adhesion between the battery and the battery attachment part.

[Example 1] Fig. 1 is an enlarged overall perspective view of a battery according to an embodiment of the present invention, Fig. 2 is a side view of the battery shown in Fig. 1, and Fig. 3 is a side view of the battery shown in Fig. 1.
FIGS. 4 and 5 are plan views showing electrode planes of the battery shown in the figure, and FIGS. 4 and 5 are plan views of the device in which the battery shown in FIG. 1 is attached to the back side of the device.

The battery of Example 1 is a button battery used in small devices such as calculators, electronic notebooks, watches, and the like.

As shown in Figures 1 and 2, the battery (battery body) 1
A male thread (threaded portion) la is formed on the side wall of the main body.

In the upper part of the battery, a head 1b having, for example, a planar circular shape is formed. For example, a flat negative (-) screw groove IC is formed in the head 1b of the battery 10. That is, the battery 1 of Example 1 has a structure that allows the battery 1 itself to be fixed to a small device using the male screw 1a. In order to fix such a battery l to a small device, it is sufficient to simply screw a screwdriver or a coin into the groove IC and rotate the battery l, for example. Therefore, the battery 1 of the first embodiment has a structure that allows for extremely easy replacement work. In the first embodiment, the male screw 1a and the head 1b are made of metal, for example.

As shown in FIG. 3, the lower surface of the battery 1 serves as an electrode forming surface. For example, a positive electrode 1d is arranged at the center of the electrode formation surface. A negative electrode 1f is arranged on the outer periphery of the positive electrode 1d with an insulating ring 1e interposed therebetween. The insulating ring 1e is a member for insulating the positive electrode 1d and the negative electrode 1f. Furthermore, an insulating ring 1g is also distributed around the outer circumference of the negative electrode 1f. The insulating ring 1g is a member for insulating the negative electrode 1f and the metal exterior portion 1h. The metal exterior part 1h has a male screw 1.
a is formed. Note that the broken line shown in FIG. 3 is the diameter of the valley of the male screw 1a.

The electronic notebook 3 has a structure that allows power to be supplied from either of the two battery mounting parts. In addition,
In order to make the drawing easier to read, the dummy battery 4 is shown with diagonal lines.

The dummy battery 4 has the same shape as the battery 1.

That is, the dummy battery 4 also has a male thread formed on its side wall, and is configured to be detachable from the battery mounting portion of the electronic notebook 3. However, the dummy battery 4 does not have the function of supplying power.

The replacement work for the battery 1 in such a case is as follows. That is, first, the dummy battery 4 is removed while the old battery 1 is still attached to the electronic notebook 3.

At this time, since the old battery 1 is securely fixed to the electronic notebook 3 by the male screw 1a, it will not come off unexpectedly due to vibration or the like. Then, instead of the dummy battery 40, a new battery 1 is screwed and fixed into the removed battery attachment part of the dummy battery 4. As a result, power is supplied to the electronic notebook 3 from the new battery 1 as well. After that, the old battery 1
, and screw the dummy battery 4 into the battery mounting part instead. As above, insert new battery 1 into electronic notebook 3.

The sealing member 5 may be formed by, for example, a bending method in which a synthetic resin is injected into a predetermined mold to form the shape of the member.

Further, as shown in FIG. 7, also in the second embodiment, the lower surface side of the battery 1 is an electrode plane. For example, a positive electrode 1d is arranged at the center of the electrode plane. A negative electrode 1f is arranged on the outer periphery of the positive electrode 1d with an insulating ring 1e interposed therebetween. However, in this case, there is no need to provide an insulating ring between the negative electrode 1f and the seal member 5.

As described above, according to the second embodiment, in addition to the effects obtained in the first embodiment, the following effects can be obtained.
