The present invention relates to a remote control for an electronic device, and more particularly, to a battery housing structure of the remote control for an electronic device to facilitate the configuration of a housing for accommodating a battery for supplying power to the remote control for the electronic device.

In general, various electronic products are provided with a remote controller for electronic devices (hereinafter, abbreviated as 'electronic device remote controller') that allows a user to control the remote device without directly operating a switch provided to the product body. The remote controller for an electronic device receives power from a battery built in itself, and outputs a selected optical signal through a light emitting diode provided at the front end by manipulating a plurality of rubber keys provided on a surface thereof.

Batteries are mainly to use a consumable battery, at least one is inserted into the battery compartment formed in the remote control body for electronic devices, the battery is standardized, the size of the compartment for accommodating the battery is also formed in accordance with the size of the battery The battery compartment is configured to be opened and closed for replacement when the power of the battery is exhausted.

Available batteries are manufactured by several companies, and the specifications of the batteries differ slightly depending on the manufacturers. Therefore, when a battery of different manufacturers is mounted in the battery compartment, a gap is formed between the wall of the compartment and the battery depending on the size. Noise may be generated by shaking due to vibration.

Therefore, the mounting structure of the battery is required to keep the negative terminal and the positive terminal of the battery to maintain the electrical connection with the substrate, and to minimize the noise generated during vibration due to the gap between the battery compartment and the battery.

Minimizing noise is a means of preventing vibration, and there is a need for improvement, and it does not exclude the noise discomfort that the user can feel by excluding the noise, and also transmits it to the substrate when the battery vibrates due to the gap with the battery. This is because a shock may cause product degradation and even damage over time.

1 is an exploded perspective view showing in detail the battery housing structure of a remote control for a conventional electronic device.

As shown in the related art, a remote control for an electronic device has a PCB 300 interposed between the upper case 100 and the lower case 200 which are detachably coupled to each other.

According to this, the upper case 100 is formed with rubber keys (not shown) formed of elastic members such as a plurality of rubber on the surface, coupled with the upper case 100 and opened and closed by a cover 220 to be described later. Shown is a lower case 200 in which an entrance 210 for opening a portion of the storage compartment 410 to the outside is formed.

The upper case 100 has a sidewall formed at a height sufficient to accommodate the thickness of the battery B mounted on the back of the PC 300 while the PC 300 is seated therein, and a hollow portion is formed inside the side wall. It is formed, the opening is formed on one side.

The lower case 200 has a shape corresponding to the upper case 100 to be engaged with the upper case 100 to form a substantially box-shaped housing, and the entrance 210 is formed on the bottom surface to open and close for storing or mounting the battery. The entrance 210 may be closed by a cover 220 of a corresponding shape.

Between the upper case 100 and the lower case 200 is installed in the front of the PC 300 is fixed a plurality of switches (not shown) that is pressed by the rubber key provided in the upper case 100.

On the rear of the PC 300, a positive terminal 330 and a negative terminal 340 are formed at predetermined intervals, and on one side, a light emitting lamp 310 for transmitting an optical signal is fixed, and each positive terminal ( 330 and the negative terminal 340 has a predetermined elasticity so as to elastically support both ends of the battery (B), which is accommodated as the interval is determined according to the number of batteries (B).

A plurality of fixing holes 320 are formed in the PC 300 along the periphery of the seated portion in which the battery B is accommodated.

Meanwhile, a plurality of fixing protrusions 420 press-fitted into the plurality of fixing holes 320 are integrally formed to provide guide ribs 400 fixed to the PC 300.

The guide rib 400 is formed in a substantially rectangular protrusion having a predetermined length projecting inwardly along the rim, and the protrusion formed adjacent to the side forms a narrow gap, which is a positive terminal 330 and a negative one. The terminal 340 is formed of the supporting grooves 430 and 440 into which the terminal 340 is inserted, and the storage chamber 410 having the maximum cross-sectional area of the battery B is formed inside the other protrusion.

The above-described protrusion contacts and supports the longitudinal side surface of the battery B mounted in the storage compartment 410, and the positive terminal 330 and the negative terminal 340 inserted into the support grooves 430 and 440 are the storage compartment. By supporting the longitudinal ends of the 410, the battery B is supported in all directions.

In particular, the positive terminal 330 and the negative terminal 340 are made of an elastic member so that the electrical connection with the PC 300 is maintained and the two ends of the battery B are elastically supported.

Operation of the conventional remote control for an electronic device having the configuration as described above is made as follows.

At the time of assembling the remote controller for the electronic device, a fixing protrusion 420 corresponding to the guide rib 400 is inserted into the fixing hole 320 formed on the back of the PC 300, and at this time, the fixing protrusion 420 is already installed in the PC 300. As the positive terminal 330 and the negative terminal 340 are inserted into the support grooves 430 and 440 which are formed adjacent to both sides of the guide rib 400 in the longitudinal direction, the guide rib 400 is integral with the PC 300. Achieve.

When the lower case 200 is assembled to the edge of the upper case 100 in a state where the PC 300 with the guide rib 400 is mounted on the upper case 100, the lower case 200 is formed in the lower case 200. The doorway 210 exposes the inside of the storage chamber 410 so that the battery B can enter and exit the positive terminal 330 in the storage chamber 410 formed inside the guide rib 400.

The battery inserted through the doorway 210 is accommodated so as to be arranged in series in the storage chamber 410, and the other end thereof is positively connected with the other end in a state in which one side is elastically supported by a conductive elastic member formed on the negative terminal 340 side. Both sides are elastically supported by being supported by the conductive elastic member formed on the 330 side.

The battery B, which is elastically supported at both ends in the longitudinal direction, is supported by the projections protruding inwardly from the guide rib 400 at the side thereof, thereby being supported from all sides and mounted stably.

When the mounting of the battery B is completed, the entrance and exit 210 is closed by the cover 220 to prevent the battery B from protruding or detaching to the outside.

Such a remote control for an electronic device according to the related art can obtain a dustproof effect of the battery to a certain extent by storing the battery in a state where all directions are supported by guide ribs and terminals therein.

However, the conventional remote controller for electronic devices has a high manufacturing cost because the guide ribs must be manufactured separately, and the size of the fixing protrusions that help the guide ribs are fixed to the PC is small and structurally weak, so that breakage is easy. Negative terminals are inserted and coupled to both ends of the guide ribs in the longitudinal direction, which may cause damage to the battery due to constant load due to vibration and weight of the battery or short circuit of the electrical connection with the PCB. Due to the limited area of the storage compartment, there is still a possibility that the mounted battery may cause vibration by not providing accurate contact support for the size of the battery having various dimensions according to the manufacturer. In the long run given the impact of There was a problem that can cause the functional weakness and even damage of the remote control device.
