Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device for remotely controlling an air conditioner and the like, and more particularly to a means for preventing reverse polarity insertion of a dry battery into a battery housing of the device.

[0002]

2. Description of the Related Art FIG. 4 shows the structure of a battery housing portion of a conventional wireless remote controller. In the figure, 1 is a wireless remote controller main body, 2 is a battery housing portion, 3 is a dry battery, 4 is a positive electrode terminal having a convex portion protruding inside the battery housing portion 2, and 5 is a spring member inside the battery housing portion 2. The formed negative electrode terminal is shown. The negative electrode terminal is in the shape of a coil spring and has a structure in which the dry battery 3 is pressed with an appropriate load. In the case of the above structure, when the dry battery is replaced, the dry battery 3 can be inserted even if the polarity is reversed.
As a result, the device may not operate, or in some cases, the circuit of the device may be destroyed. For example, when the dry batteries are connected in series and one of them is reversely inserted, the voltage applied to the load will be a differential voltage that cancels each other out, and the battery energy will not be effectively supplied to the load. Will not be done. Not only that, but for one of the dry batteries, a charging current would flow, causing the battery to generate heat, which could lead to explosion.

SUMMARY OF THE INVENTION In view of the above problems, the present invention has a plurality of ribs internally provided inside a battery housing and utilizes a positive electrode convex portion of a dry battery to insert the battery with reverse polarity. The purpose is to provide a means to prevent.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and different electrode terminals for receiving batteries are provided on both inner sides of a battery housing formed in the body of the wireless remote controller. In a structure in which a plurality of batteries are arranged for each polarity and a dry battery is stored in the battery storage portion, opposing ribs for preventing erroneous insertion of the dry battery between different polarities of the electrode terminals of the battery storage portion. It is characterized by being installed internally. The distance between the tips of the ribs facing each other is shorter than the dimension of the dry battery.
Further, a spring material is used for the negative electrode of the electrode terminal, and the rib is provided inside two adjacent dry batteries. Also, two spring members are used for each of the dry batteries for the negative electrode of the electrode terminal, and the rib is internally provided between the two negative electrodes. Further, the rib is provided adjacent to the positive electrode of the electrode terminal. Further, the rib is integrally formed with the main body of the wireless remote controller.

[0005]

With the above structure, when the dry battery is inserted in the reverse polarity by the ribs provided on both inner sides of the battery housing, the convex portion of the positive electrode of the dry battery hits the rib and cannot be inserted, and the reverse of the dry battery is prevented. The insertion of polarity can be prevented.

[0006]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. 1 and 2A, 1
Is a main body of the wireless remote controller, 2 is a battery storage unit for storing a plurality of dry batteries, 3 is a dry battery, 4 is a positive electrode terminal of a battery receiver provided inside both sides of the battery storage unit 2, and receiving the dry battery 3. Is a negative electrode terminal of a battery receiver, which is internally provided on both sides inside the battery housing 2 and is formed of a coiled spring material for receiving the dry battery 3, and 6 is the battery housing 2
Positive electrode terminals 4 of the battery receiver, which are internally provided on both sides of the
Between the negative electrode terminal 5 of the battery receiver and the negative electrode terminal 5 of the battery receiver.

In the above structure, the negative electrode terminal 5 of the battery receiver is in the shape of a coil spring and is higher than the height of the rib 6 so that the dry battery 3 is pressed with an appropriate load. The width of the rib 6 is formed to straddle the dry batteries 3 adjacent to each other, and the distance between the tips of the ribs facing each other is the length of the dry battery 3, that is, the distance between the ends of both electrode terminals. Configured to be shorter than. Therefore, as shown in FIG. 2B, when the dry battery 3 is inserted in the reverse polarity, the convex portion of the positive electrode of the dry battery 3 hits the rib 6 and cannot be inserted, and the reverse polarity of the dry battery 3 is lost. Can be prevented from being inserted.

Further, as shown in another embodiment of FIG. 3, two negative electrode terminals 5 for the battery receiver are provided for each dry battery 3, and the rib 6 is provided between the electrode terminals.
Since the rib 6 is provided adjacent to the positive electrode terminal 4 of the battery receiver, the reverse polarity insertion of the dry battery 3 can be prevented as in the above embodiment. Further, in the above structure, the rib may be molded integrally with the main body of the wireless remote controller with a synthetic resin or the like.

[0009]

As described above, according to the present invention, the ribs provided on both sides of the inside of the battery housing can prevent the insertion of the positive electrode of the dry battery due to the reverse polarity. As a result, it is possible to prevent the problem that the device does not operate or the circuit of the device is broken, and in some cases, there is a risk of causing heat generation or explosion of the battery.
