Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode terminal of a battery holder in various electronic devices, electric devices and the like.

[0002]

2. Description of the Related Art An electric device or the like which operates by using a battery as a power source has a battery holder in which a battery is loaded in order to take out electric power. A conventional battery holder has a positive electrode terminal and a negative electrode terminal, which are in contact with respective electrodes of a battery, provided therein. Loading of the battery into the battery holder is usually performed by confirming the relative positions of polarities so that the positive electrode faces the positive electrode terminal and the negative electrode faces the negative electrode terminal.

[0003]

Therefore, in the prior art, it was necessary to match the polarities of the electrodes of the battery with the polarities of the electrode terminals of the battery holder, which required great care in loading the battery. Also, when batteries are loaded with the opposite polarity,
In addition to the malfunction of the electric equipment, the electric circuit has a malfunction and the battery power is consumed. In response to such inconvenience, various proposals have been made to prevent electric power from being taken out when the battery is not loaded with the correct polarity. However, for people with little knowledge of electricity or blind people, if the electric device does not work well, it may be due to a wrong connection of the battery, whether the battery is exhausted, or there is a problem with the electric device. There was a problem that it could not be determined. There was an idea to use a diode to electronically supply electric power of the correct polarity to electric equipment regardless of the polarity of the battery, but since there is a voltage drop due to the diode, in an electric / electronic circuit that operates at a low voltage There was a problem that the voltage loss was large.

Therefore, the problem to be solved by the present invention is to provide an electrode terminal of a battery holder that does not require confirmation of the polarity of the battery and can take out electric power without loss even if the battery is loaded in any direction. To do.

[0005]

In order to solve this problem, the electrode terminal of the battery holder of the present invention has a positive electrode terminal that contacts the positive electrode of the battery in the opposing electrode terminal portion of the battery holder in which the battery is loaded. And a negative electrode terminal that contacts the negative electrode of the battery are provided, and the positive electrode terminal on one side and the positive electrode terminal on the other side are electrically connected to lead out a positive electrode lead wire,
Further, the negative electrode lead wire is led out by electrically connecting the negative electrode terminal on one side and the negative electrode terminal on the other side.

When a plurality of batteries are connected in series, the above-mentioned positive electrode lead wires and respective negative electrode lead wires are connected in series, and a voltage is taken out from the positive electrode lead wire and the negative electrode lead wire at both ends. Even if the polarities and directions of the batteries are different, as many series voltages as there are batteries can be taken out.

When the battery is a button battery, since the positive and negative electrodes are not arranged on the opposite sides of the battery, the positive electrode terminal that contacts the case side portion of the button battery and the negative electrode surface of the button battery and the opposite side. A pair of negative electrodes arranged on the surface and supported by a ridge, and a short-circuit prevention insulating protrusion provided on the negative terminals and adapted to bring the negative terminals into contact with the negative electrode when the negative terminals are fitted into the concave portion of the negative edge of the button battery. And the configuration.

[0008]

Since the positive electrode terminal and the negative electrode terminal are provided on the opposite electrode terminal portions of the battery holder, no matter which direction the battery is loaded, the positive electrode of the battery is the positive electrode terminal of the battery holder and the negative electrode is The positive electrode voltage is always applied to the positive electrode lead wire, the positive electrode voltage is always applied to the negative electrode lead wire, and the negative electrode voltage is always applied to the negative electrode lead wire, so that electric power is supplied to the electric device with correct polarity.

Further, in the case of a button battery, the positive electrode terminal is brought into contact with the side of the battery case by paying attention to the fact that the side of the battery case is the positive electrode regardless of the orientation of the battery. Is placed on the front and back of the battery, and since there is a recessed insulating portion around the negative electrode, an insulating protrusion is provided so that the negative electrode terminal on the negative electrode side comes into contact with the insulating portion. Since the positive electrode terminal on the opposite surface of the battery does not have the concave portion, the negative electrode terminal is separated from the surface of the battery by the insulating protrusion and does not contact with each other, so that a short circuit between the positive electrode terminal and the negative electrode terminal can be prevented.

EXAMPLES The present invention will be specifically described below based on examples.

1 to 3 show an embodiment in which the present invention is applied to a holder for dry batteries, and FIG. 1 shows a normal loading state.
Indicates the opposite loading state. In the present invention, since the directionality of the battery has disappeared, there is no notion of “normal” and “opposite” in the direction of the battery, and the directions are equal, but for convenience of explanation, a certain direction is “normal” and The opposite direction is called "opposite".

1 to 3, a positive electrode terminal 1 and a negative electrode terminal 2 are provided at opposite positions in a battery holder,
The positive electrode terminal 1 and the negative electrode terminal 2 are connected to the (+) side input terminal 3 and the (−) side input terminal 4 of an electric device or the like via lead wires 5 and 6, respectively. When a normal battery is loaded, as shown in FIG.
Of the dry battery 10 and the negative electrode terminal 2 is in contact with the positive electrode 11 of
The electric power is output to an electric device or the like in contact with the electric power generator 2. In addition to this, the negative electrode auxiliary terminal 7 is juxtaposed in the proximity position on the positive electrode terminal 1 side, and the positive electrode auxiliary terminal 8 is juxtaposed in the proximity position on the negative electrode terminal 2 side. The negative electrode auxiliary terminal 7 is electrically connected to the negative electrode terminal 2 via the lead wire 6, and the positive electrode auxiliary terminal 8 is electrically connected to the positive electrode terminal 1 via the lead wire 5. In this case, the distance between the negative electrode auxiliary terminal 7 and the positive electrode auxiliary terminal 8 is substantially equal to the distance between the positive electrode terminal 1 and the negative electrode terminal 2, and therefore the distance between the auxiliary terminals 7 and 8 is substantially the same as the entire length of the dry battery 10. There is. Further, as shown in FIG. 3, the negative electrode auxiliary terminal 7 is shorter than the positive electrode terminal 1, so that the negative electrode auxiliary terminal 7 does not come into contact with the positive electrode 11 of the dry battery 10 during normal battery loading. On the other hand, although the positive electrode auxiliary terminal 8 is longer than the negative electrode terminal 2 as shown in FIG. 1, it is arranged outside the negative electrode terminal 2 with respect to the battery loading position. Therefore,
Under normal battery loading, the positive electrode auxiliary terminal 8 does not come into contact with the negative electrode (seat plate) 12 of the dry battery 10.

In the above structure, when the battery is normally loaded, the positive electrode terminal 1 contacts the positive electrode 11 of the dry battery 10 and the negative electrode terminal 2 contacts the negative electrode 12 of the dry battery 10 to output electric power, as shown in FIG. . On the other hand, when the battery is loaded in the opposite direction shown in FIG. 2, the negative electrode auxiliary terminal 7 contacts the negative electrode 12 of the battery 10, and the positive electrode auxiliary terminal 8 contacts the positive electrode 11 of the battery 10.
The load auxiliary terminal 7 is electrically connected to the negative electrode terminal 2 and has the same polarity as the terminal 2, and the positive electrode auxiliary terminal 8 is electrically connected to the positive electrode terminal 1 and has the same polarity. Therefore, power can be output normally. Therefore,
According to the above configuration, since the electric power can be taken out regardless of the direction of loading the battery without considering the polarity of the battery, the battery can be loaded regardless of unfamiliarity or darkness, and the electric device can be installed. It is possible to prevent the breakdown of the battery and the consumption of the battery.

As shown in FIG. 7, the button battery 30 is housed with the positive electrode active substance 34 on the lower side and the negative electrode active substance 35 on the upper side through the separator 33. The case that accommodates these becomes the positive electrode 31 by coming into contact with the positive electrode active substance 34. Further, the cap that covers the case becomes the negative electrode 32 by coming into contact with the negative electrode acting substance 35. And this positive electrode 3
An insulator 36 is filled between 1 and the negative electrode 32 to electrically interrupt them.

The present embodiment applied to such a button battery 30 is, as shown in FIGS. 4 and 5, a button battery 30.

As shown in FIG. 6, an insulating protrusion 27 hangs down from the negative electrode terminal 22, and the insulating protrusion 27 comes into contact with the vicinity of the insulator 36 of the button battery 30 so that the negative electrode terminal 22 is positive electrode of the button battery 30. It is held so as not to contact 31. In addition to the above, a negative electrode auxiliary terminal 28 is provided in the battery holder.

The load auxiliary terminal 28 is provided so as to extend from the positive electrode terminal 21 side toward the bottom surface of the button battery 30 (the positive electrode of the button battery 30 in the normal loading shown in FIG. 4) and faces the negative electrode terminal 22. The negative electrode auxiliary terminal 28 is electrically connected to the negative electrode terminal 22 via the lead wire 26. Further, an insulating protrusion 29 similar to the insulating protrusion 27 of the negative electrode terminal 22 is formed on the negative electrode auxiliary terminal 28 so as to project toward the button battery 30.

FIG. 4 shows a state in which the button cell battery 30 is normally loaded. The positive electrode terminal 21 contacts the side surface of the positive electrode 31 and the negative electrode terminal 22 contacts the negative electrode 32 to output electric power. At this time, since the insulating protrusion 29 of the negative electrode auxiliary terminal 28 contacts the bottom surface of the button battery 30 which is the positive electrode 31, the short circuit is prevented without contacting the button battery 30. FIG. 5 shows a state in which the button battery 30 is inverted and loaded. In this loaded state, the positive electrode terminal 21 contacts the positive electrode 31 of the button battery, while the negative electrode auxiliary terminal 28 contacts the negative electrode of the button battery 30. This negative electrode auxiliary terminal 28
Is electrically connected to the negative electrode terminal 22 via a lead wire 26 and has the same polarity as the terminal 22. For this reason,
Even in the case of reverse loading, power can be output normally. At this time, the insulating protrusion 27 of the negative electrode terminal 22 is in contact with the bottom surface of the button battery 30 to prevent the contact with the positive electrode 31. Therefore, in this embodiment, even the button battery 30 can be loaded without having to consider its polarity.

The above is an example in the case of a single battery,
An example in which a plurality of batteries are connected with the correct polarity will be described below.
