Description

Battery storage structure of remote controller

The present invention relates to a remote controller, and more particularly, to a battery housing structure of a remote controller that can easily configure a housing for accommodating a battery for supplying power to the remote controller.

In general, a variety of electronic products are provided with a remote controller (hereinafter, abbreviated as "remote control") that allows the user to control from a long distance without directly operating a switch provided to the product body. The remote controller is supplied with power from a battery built in itself and outputs a selected optical signal through a light emitting diode provided at the front end by a plurality of key manipulations provided on the surface.

The battery mainly uses a consumable battery, one or two of which are inserted into the battery compartment formed in the remote controller main body. In addition, the battery is standardized, and the size of the accommodating part for accommodating the battery must also be formed to match the size of the battery. The battery compartment should be configured to be open and close for replacement when the battery power is exhausted, and the occurrence of noise due to the flow should be small by minimizing the flow of the stored battery.

In this regard, a battery accommodating structure as illustrated in FIG. 1 has been developed. 1 is an exploded view of the remote control in an inverted state, and accordingly, the remote control is interposed between the upper case 10 and the lower case 20 which are detachably coupled to each other.

On the rear surface of the printed circuit board 30, the + terminal 34 in contact with the + terminal of the battery B and the-terminal 36 in contact with the-terminal are fixed at regular intervals. Each connection terminal is soldered onto the printed circuit board 30 and retains elasticity to elastically support a battery arranged therebetween. On one side of the printed circuit board 30, a light emitting lamp 32 for transmitting an optical signal is fixed.

On the other hand, the lower case 20 is formed with an entrance 28 to open and close the portion where the battery (B) is seated to open and close by the cover 21. In the periphery of the entrance and exit 28, the substantially rectangular guide rib 22 which is arranged between each connection terminal 34 and 36 and forms the storage chamber 22a which accommodates the battery B without flow is formed integrally. At both ends of the guide rib 22, support grooves 24 and 26 supporting the + terminal 34 and the-terminal 36 are formed.

Looking at the assembling process of the remote control having such a configuration, as shown in FIG. 2, the + terminal 34 and-in the state in which the + terminal 34 and the-terminal 36 are soldered and fixed on the printed circuit board 30. The lower case 20 is assembled to the printed circuit board 30 by inserting the terminal 36 into the support grooves 24 and 26 of the lower case 20, and the upper case 10 is assembled into the lower case 20. ) To assemble. Alternatively, assembling the printed circuit board 30 and the upper case 10 in which the + terminal 34 and the-terminal 36 are assembled first, and then each of the connecting terminals 34 and 36 support the supporting grooves 24 and 26. The lower case 20 and the printed circuit board 30 may be assembled to be fitted into the lower case 20.

However, the conventional battery accommodating structure has a problem that the assembly work is delayed and the appearance of the case is poor.

That is, the structure as described above is supported when the + terminal 34 and the-terminal 36 fixed on the printed circuit board 30 to the support grooves 24 and 26 of the guide rib 22. (24) (26) becomes invisible to the naked eye, which causes a problem of poor assembly. In other words, when the + terminal 34 and the − terminal 36 and the support grooves 24 and 26 are coupled, a relatively wide printed circuit board 30 covers the support grooves 24 and 26, thereby supporting the operator. Since the positions of the grooves 24 and 26 can not be confirmed, not only a skilled worker is required but also a problem of high failure rate after assembly.

In addition, the upper case 10 and the lower case 20 of the remote control is mainly formed of a synthetic resin, the recent molding technology is a trend that the thickness of the injection molding is becoming thin. However, since the guide ribs 22 are integrally molded to the lower case 20 as described above, shrinkage proceeds to the protruding portion thereof, resulting in a poor surface state of the lower case 20, resulting in inferior merchandise.

Accordingly, the present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a battery accommodating structure of a remote controller that can improve the assemblability and maintain a good appearance of a product.
