[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device, such as a remote controller, in which a battery housing is provided in one of two cases having a divided structure.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional example of a remote controller which is an example of this kind of electronic equipment. The remote controller 5 shown in the figure has a combination in which switches are arranged on a surface portion not shown in the figure, a wiring board 12 is fixed inside, and a battery housing 14 is provided below the wiring board 12. It has a resin upper case 10 and a synthetic resin lower case 20 that covers and fits the upper case 10.

The upper case 10 has a fitting portion provided on an outer peripheral portion of an upper surface of the lower case 20 at an outer peripheral portion of the lower case 20 as can be clearly understood from FIG. 6 showing a state where the lower case 20 is fitted. A fitting portion 11 fitted to the fitting portion 21 is provided, and a pair of two batteries (AA) 30 for holding two dry batteries (AA) 30 that define both ends of the battery housing portion 14 on the inner peripheral side of the fitting portion 11 are provided. And the battery 30 is connected to the terminal receiving holder 1 via a pair of wire terminals 16 wound in a coil shape.
The holding pressure is maintained at 5,15.

[0004] A reinforcing rib 17 is provided on the base side of the terminal receiving holder 15, and one end (opposite to the battery side) of the terminal wire 16 is provided on the terminal receiving holder 15 so as to pass below the reinforcing rib 17. It is routed outward from the cutout 18 and is connected to the wiring board 12.

[0005]

In the remote controller 5 having the case structure as described above, since the terminal receiving holders 15 and 15 hold the battery 30 with pressure, the terminal receiving holders 15 and 15 have the same structure. A force is applied to 15 to push it outward.

However, the terminal receiving holders 15 and 15 have a structure in which they are erected downward on the upper case 10.
In addition, the reinforcing rib 17 can be provided only at the base portion. That is, since the height of the terminal holders 15, 15 is higher than the depth of the upper case 10, the reinforcing ribs 17 are connected to the terminal holders 15, 15.
If the wire terminal 1 is provided up to the tip of the wire terminal 1, the lower case 20 may not be fitted to the upper case 10.
6 will be hindered.

As a result, the terminal receiving holders 15 and 15 are always slightly bent outward when the battery is held. Therefore, the terminal receiving holders 15 and 15 are deformed over time to reduce the spring load, and the battery 30 and the wire terminals 16 are reduced. This may cause poor contact with the device, and may impair reliability.

In view of the above, the present invention makes it difficult to deform the terminal receiving holder erected in the case, thereby making it difficult to cause a battery contact failure and the like, thereby improving reliability. It is an object to provide an electronic device such as a remote controller having a case structure.

[0009]

In order to achieve the above object, an electronic apparatus according to the present invention includes a first case having a battery storage portion having terminal receiving holders provided on both ends thereof, and a first case having the first case. A second case fitted so as to cover the case, wherein the second case is provided with a reinforcing rib which is in contact with the outer surface of the distal end portion of the terminal receiving holder.

[0010]

In the electronic device according to the present invention having the above-described structure, a reinforcing rib is provided on the second case side where the battery housing portion is not provided so as to be in contact with the outer surface of the distal end portion of the terminal receiving holder. Therefore, the terminal receiving holder can be hardly deformed, and it is hard to cause poor contact of the battery. As a result, the reliability is improved.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 3 show an embodiment of an electronic device according to the present invention. The electronic device 1 of this embodiment corresponds to each part of the conventional device shown in FIGS. 5 and 6 described above. The same reference numerals are given to the portions, and the duplicate description thereof will be omitted, and the differences will be mainly described below.

The electronic apparatus 1 of this embodiment is different from the conventional one in that reinforcing ribs are provided on the lower case 20 so as to be erected downward on the upper case 10 and contact the outer surfaces of the distal end portions of the terminal receiving holders 15 and 15. 25 is provided.

The reinforcing ribs 25 are arranged in two lines on the inner surface of the side portion 20a of the lower case 20 as shown in FIG. To this end, a chamfer 25a is applied to the tip,
Further, the distal end surface is formed slightly apart from the upper end surface (fitting portion 21) of the lower case 20, and is configured so that the fitting portion 11 of the upper case 10 is fitted in abutting manner.

Further, it is best that the reinforcing ribs 25 are provided in two rows so as to be opposed to the reinforcing ribs 17 of the upper case 10. However, the reinforcing ribs need not always be provided at the opposed positions. It may be integrally formed thick along the inner surface of the portion 20a.

As described above, the terminal receiving holders 15 and 15 are provided on the lower case 20 side where the battery housing 14 is not provided.
15 is provided with a reinforcing rib 25 in contact with the outer surface of the distal end of the lower case 20.
When the terminal holder 1 is fitted, the reinforcing ribs 25 come into contact with the outer surfaces of the distal ends of the holders 15, 15.
5 and 15 are hardly deformed, so that poor contact of the battery 30 is hardly caused. As a result, reliability is improved.

FIG. 4 shows another embodiment of the electronic device according to the present invention. In this embodiment, the electronic device 6 is integrated with a side portion 20a of the lower case 20 and has a tip end surface formed of the lower case 20. A reinforcing rib 25 is provided flush with the upper end surface of the upper case 10 so that the strength is further enhanced and the fitting portions 11 and 21 between the upper case 10 and the lower case 20 are provided.
An example in which an annular concave groove 8 on a design is formed in a portion is shown. In this embodiment, the same operation and effect as those of the first embodiment can be obtained.

[0017]

As is apparent from the above description, the electronic device according to the present invention has a reinforcing rib in contact with the outer surface of the distal end of the terminal receiving holder on the second case side where the battery housing is not provided. Because it is provided, it is difficult to deform the terminal receiving holder and it is difficult to cause poor contact of the battery,
As a result, reliability can be improved.
