Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery accommodating mechanism for electronic equipment using a battery.

[0002]

2. Description of the Related Art In recent years, electronic devices such as an information terminal which can be freely carried indoors and out, an electronic mail, and a mail terminal which can be connected to the Internet have been widely used. For example, there is a device for inputting with a keyboard, a device for inputting with a pen touch on the display unit, and the like. Information input to such an electronic device is usually temporarily stored in a RAM such as a built-in microcomputer or memory. The stored information is held by a power source such as a dry battery or a rechargeable battery.

FIG. 3 shows an example of a conventional power supply for electronic equipment. As shown in the figure, the battery 3 is stored in the battery storage portion 2 of the electronic device 1. The positive electrode 4 of the battery 3 is in contact with the positive terminal 5 arranged in the battery housing 2, and the negative electrode 6 of the battery 3 is in contact with the negative terminal 7 arranged in the battery housing 2. Each of the plus terminal 5 and the minus terminal 7 is electrically connected to a power supply circuit board 8 for driving the electronic device 1 so that power is supplied to the circuit by the battery 3.

The positive electrode 4 of the battery 3 and the positive terminal 5 of the battery housing 2 are in contact with each other, and the negative electrode 6 of the battery 3 and the negative terminal 7 of the battery housing 2 are not in contact with each other with some pressure. And the contact resistance increases and the voltage drops. Therefore, in general, the negative terminal 7 of the battery housing 2 is
Uses a coil spring or a leaf spring, and has a structure that comes into contact with the battery 3 with pressure.

[0005]

However, in an electronic device using a battery as a power source as described above, as shown in FIG. 3, in particular, when it is dropped in the direction of arrow A from the minus terminal 7 side using a spring material, Upon impact with the ground, the spring of the negative terminal 7 is instantly compressed by the inertia of the battery 3. As a result, the plus electrode 4 is separated from the plus terminal 5 instantaneously. Therefore, there is a problem that the power of the electronic device 1 is momentarily turned off and the data stored in the RAM is erased.

As a countermeasure against this, conventionally, a method of attaching a secondary battery for backup, a method of attaching a spring also to the positive terminal side, etc. have been taken. However, the method of using the secondary battery increases the cost and the battery. It is troublesome to check the battery life and replace the battery. Further, the method of attaching a spring to the positive terminal side is also troublesome to replace the battery, so that it is the current state that it is hardly adopted in electronic devices used by general users.

The present invention solves the above-mentioned conventional problems, and it prevents a momentary power interruption due to a drop impact of an electronic device, and a battery storing mechanism which does not hinder the taking in and out of a battery by a simple method at a small cost. The purpose is to provide.

[0008]

In order to solve this problem, a battery housing mechanism of the present invention has an opening for attaching and detaching the battery in a part of a housing and a negative electrode of the battery when the battery is housed. A spring-shaped terminal in contact, a holding member for holding the positive electrode of the battery, a fixed portion near the holding member, one side fixed to the housing, and the other side rotatably supported by the housing. And a tip portion extending from the support portion contacts and separates from the positive electrode of the battery, and a part between the fixed portion and the support portion projects toward the opening portion. And a battery lid that opens and closes the opening provided with an abutting piece that presses the protruding portion of the elastic terminal. As the lid opens and closes, the tip of the elastic terminal will It has a configuration which is adapted to contact and separation to electrode.

With such a structure, even if the plus electrode and the plus terminal are momentarily separated by the spring contraction of the minus terminal when the electronic device is dropped, the elastic terminal can be kept in contact with the plus electrode.

The holding member for holding the positive electrode of the battery is a positive terminal.

With this structure, even if the battery lid is opened carelessly and the elastic terminal is momentarily separated from the positive electrode of the battery, the positive terminal provided by this holding member maintains the power supply continuity.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 are a partial configuration diagram and a circuit configuration diagram of a battery accommodating mechanism according to an embodiment of the present invention, in which the same components as those in the conventional example are designated by the same reference numerals and the description thereof is omitted. .

In the figure, a battery housing portion 2, a battery attaching / detaching opening 9 of the battery housing portion 2, and a battery lid 10 for opening / closing the opening portion are provided in a part of a housing 11 of the electronic device 1. A battery storage mechanism is formed. The battery 3 is stored in the battery storage portion 2, and the positive electrode 4 of the battery 3 is formed so as to be held in contact with the holding member 12. An elastic terminal 13 made of a conductive metal plate or wire is arranged near the holding member 12 side. One end of the elastic terminal 13 is fixed to a fixing portion 14 provided in the housing 11, and the elastic terminal 13 is connected to the power supply circuit board 8 by a lead wire 15 or the like and is connected to the battery 3
It is formed so as to supply a positive power source.

The other side of the elastic terminal 13 is rotatably supported by the support portion 17 on the housing 11 near the plus electrode 4 in the direction of arrow C. Further, the other side of the elastic terminal 13 is further extended from the support portion 17, and the tip portion 13
a is arranged so as to face the positive electrode 4 of the battery 3.
Further, a part of the elastic terminal 13 between the fixed part 14 and the support part 17 is formed with a protrusion 13b so as to protrude toward the opening 9. On the other hand, the battery lid 10 is provided with a contact piece 18 on its inner surface for pressing the protruding portion 13b of the elastic terminal 13. That is, when the battery lid 10 is inserted from the direction of the arrow B, the projecting portion 13b of the elastic terminal 13 is pressed by the contact piece 18, so that as shown by the broken line in FIG. Between the bearing parts 17 is deformed, and the bearing part 1
By the rotation of 7, the tip portion 13a of the elastic terminal 13 is moved to the arrow C.
And is pressed against the positive electrode 4 of the battery 3.

That is, after the battery 3 is inserted and the battery lid 10 is closed, power is supplied to the circuit. With such a structure, the movement of the battery 3 due to the spring contraction of the negative terminal 7 when the battery 3 is dropped with the negative terminal 7 side down is followed by the pressurizing elastic terminal 13 to follow the movement of the battery 3. Since it is possible to prevent the power supply from being cut off, input data and the like can be protected.

When the battery lid 10 is opened in the direction opposite to the arrow B direction, the projecting portion 13b of the elastic terminal 13 is disengaged from the abutting piece 18 and returned to its original position by the elastic force, and the tip portion 13a is moved to the plus electrode 4a. It is further separated, and the battery 3 can be easily taken in and out.

According to this principle, instead of the abutting piece 18 of the battery cover 10, a slidable lock lever (not shown) is attached to the battery cover 10 so as to urge or release the pressing on the protrusion 13b of the elastic terminal 13. Even if it is provided, the same effect can be obtained.

If the holding member 12 for holding the plus electrode 4 of the battery 3 is used as a plus terminal and is connected in parallel to the elastic terminal 13 to the power supply circuit, the battery lid 10 is accidentally opened and the elastic terminal 13 is momentarily opened. Even if the battery 3 is separated from the plus terminal 4 of the battery 3, the effect that the power supply continuity is held by the plus terminal of the holding member 12 can be obtained.

[0020]

As described above in detail, in the battery storing mechanism of the present invention, the momentary movement of the battery due to the contraction of the spring of the negative terminal when the electronic device is dropped causes the elastic terminal to follow the movement of the battery, and The effect of protecting the input data and the like by preventing momentary disconnection can be obtained.

When the battery cover is opened when replacing the battery,
Only the minus terminal applies the biasing force to the battery, so the battery can be easily attached and detached.

Further, since the holding member for holding the positive electrode of the battery is used as the electrode terminal, the battery lid 1 is inadvertently used.
Even if 0 is opened and the elastic terminal is momentarily separated from the plus terminal, the effect that the power supply continuity is maintained by the electrode terminal by this holding member is obtained.

Therefore, there is almost no increase in cost,
It is easy to assemble by setting the elastic terminal, and it does not bother the general user for taking in and out of the battery. There are many effects that can prevent the target disconnection.
