Description

  The present invention relates to a mechanism capable of switching two or more batteries to a series connection or a parallel connection by a simple switching operation.

  In science learning, scientific experiments, models, and the like, a plurality of batteries may be used in series connection or in parallel connection. In such a case, it has been troublesome to change a plurality of batteries in series and change electrodes, or change a plurality of batteries in parallel and change electrodes.

For example, a case where a light bulb lighting experiment is performed by serial / parallel switching in science learning using two battery holders 100 and 200 each capable of setting two batteries as shown in FIG. 3 will be described. .
In the case of series connection, as shown in FIG. 4, for example, the first battery B <b> 1 is set in the first set part 110 of one first battery holder 100, and the other second battery holder 200 is The second battery B2 is set in the first setting unit 210. For example, the positive electrode 112 of the first battery B1 and the negative electrode 211 of the second battery B2 are connected by a conductive wire 310. The one lead wire 410 of the miniature bulb 400 is connected to the negative electrode 111 of the first battery B1, and the other lead wire 420 of the mini bulb 400 is connected to the positive electrode 212 of the second battery B2. To light up. In this case, since the connection is in series, it can be confirmed that the miniature light bulb is lit brightly.

When switching from serial connection to parallel connection, as shown in FIG. 5, the first battery B1 is set in the first set part 110 of one first battery holder 100, and the other battery The second battery B2 is removed from the second battery holder 200, and set in the same direction as the first battery B1 in the second set portion 120 of the first battery holder 100.
Subsequently, for example, the negative electrode 111 of the first battery B1 and the negative electrode 121 of the second battery B2 are connected by a conducting wire 320, and the first battery holder 100 and the second battery 121 are connected. The conductive wire 310 connected to the battery holder 200 is removed, and the positive electrode 112 of the first battery B1 and the positive electrode 122 of the second battery B2 are connected by the conductive wire 330. .

  Then, while the one lead wire 410 of the miniature bulb 400 is connected to the negative electrode 111 of the first battery B1, the other lead wire 420 of the miniature bulb 400 is connected to the second battery holder 200. The miniature light bulb 400 is turned on by removing it from the electrode 212 and reconnecting it to the positive side electrodes 112 and 122 of the first or second battery of the first battery holder 100. In this case, since it is connected in parallel, the brightness of the miniature light bulb is darker than that of the serial connection, but it can be continuously lit for a long time.

  When switching from parallel connection to serial connection again, as described above, the connection is changed to the serial connection as shown in FIG.

As described above, in order to perform an experiment by switching between serial connection and parallel connection, many procedures are required, which is troublesome, and there is a problem that a learning effect or the like cannot be sufficiently obtained.
Also, if the lead wires are connected incorrectly, the battery may be short-circuited, which is dangerous.
In addition, although the circuit structure which can mutually switch a serial connection and a parallel connection using the change switch of 2 circuits 2 contacts is proposed in patent document 1, etc., in this case, a serial connection and Since the difference in parallel connection cannot be visually recognized, it was inappropriate for science learning.
