The voltage of the battery 20 is applied to 0 in the opposite direction. However, in this case, the polarity of the applied voltage and the preset polarity do not match, so that the polarity detection unit 40 operates in the open / close control unit 50.
Signal is not output to. Therefore, since the opening / closing control unit 50 and the opening / closing unit 60 do not operate, the opening / closing unit 60 keeps the main circuit switch open, and the reverse voltage from the battery 20 is not applied to the load 70 and other battery erroneous insertion protection means. .
According to the battery misinsertion protection device of the present embodiment described above, the opening / closing portion can be simplified and the cost can be reduced.

In FIG. 3A, the movable electrode portion 31 when the battery 20 is not inserted is pushed up by the spring 33 and restricted by the lock portion 90 so that the movable electrode portion 31 cannot contact the fixed electrode portion 32. Here, when the battery 20 is inserted into the battery box 21 in the normal direction, the polarity detection unit 40 outputs a polarity signal to the opening / closing control unit 50, and the opening / closing control unit 50 having input this outputs a control signal to the driving unit 80. To do. As a result, the driving unit 80 causes the movable electrode unit 3 to respond to the force of the spring.
The lock part 90 is immersed from the movement path of 1. Here, for example, when the battery box 21 is covered with the lid 22 and the battery 20 is pushed down, the movable electrode portion 31 moves to the fixed electrode portion 32, and the both 31 and 32 are connected. As a result, the power of the battery 70 is supplied to the load 70 via the main circuit. Further, since the contact of the switch 34 is opened by the downward movement of the movable electrode section 31, the connection between the opening / closing control section 50 and the driving section 80 is disconnected, and the lock section 90 is moved toward the moving path side of the movable electrode section 31 by the spring. Be energized. However, in this state,
Since the movable electrode part 31 is moving to the fixed electrode side,
The lock 90 is in a state in which it cannot be projected (see FIG. 3).
(B)). When the battery 20 is taken out from the battery box 21, the movable electrode portion 31 is pushed by the spring 33 to move, and the lock portion 90 projects to return to the state of FIG.
