DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing for a communication device suspended from, for example, an overhead communication cable stretched between telephone poles, and a communication device using the housing.

[0002]

2. Description of the Related Art For example, a communication device housing shown in FIG. 3 is used for this type of communication device. In the communication device housing of FIG. 3, a waterproof packing 3 is sandwiched between the housing case 1 and one housing cover 2 for closing an open surface thereof, thereby waterproofing the internal space of the housing case 1. .

As shown in FIG. 4, there is also a communication device housing in which the inside of a housing case 4 is divided into an electronic device housing portion 6 and a cable connection portion housing portion 7 by a partition wall 5. The electronic device housing section 6 is a space for housing electronic devices. The cable connection section housing section 7 is a space for housing the cable connection section. Also in this case, the open surface of the housing case 4 is closed by one housing cover (not shown).

[0004]

In the case of FIG. 3, since a plurality of internal elements having different waterproof levels are accommodated in one internal space, the entire internal space is waterproofed according to the element having the highest waterproof level. There is a need to. Therefore, it is difficult to provide appropriate waterproofness.

In the housing shown in FIG. 4, since the electronic device housing 5 and the cable connecting portion housing 6 are partitioned, a pressure difference between the electronic device housing 5 and the outside may occur due to a change in ambient temperature. Therefore, there is a problem that dew condensation easily occurs. Further, since the open surface of the housing case 4 is closed by one housing cover, it is also difficult to provide appropriate waterproofness.

[0006] In any case, the operability is inferior because the operation cannot be performed in a state where only a specific internal element is exposed. Moreover, after operation, the reliability of the internal elements not operated is reduced.

[0007] Therefore, an object of the present invention is to provide a communication device housing with improved operability.

Another object of the present invention is to provide a communication device housing which can improve reliability because only a specific internal element can be operated without affecting other internal elements.

[0009]

According to the present invention, the internal space of the housing case is partitioned into an electronic device accommodating portion, a cable connecting portion accommodating portion, and a battery accommodating portion, which are independent spaces by a partition. A housing cover that can be opened and closed independently of the housing unit, the cable connection unit housing unit, and the battery housing unit is provided, the electronic device housing unit is set to be waterproof, and the cable connection unit housing unit is protected. The communication device housing is characterized in that the ventilation is freely set with the drops, and the battery housing is set to be freely immersed and freely ventilated.

It is preferable that a pressure adjusting hole is provided between the electronic device housing portion and the cable connection portion housing portion.

It is preferable that the pressure adjusting hole has a gas permeable membrane.

According to the present invention, an electronic device is accommodated in the electronic device accommodating portion of the communication device housing, a cable connecting portion is accommodated in the cable connecting portion accommodating portion, and a battery is accommodated in the battery accommodating portion. A communication device characterized by being housed is obtained.

[0013]

FIG. 1 is a perspective view of a communication device housing according to an embodiment of the present invention. The communication device housing includes a housing case 11 having an open front. Case 11
The first, second, and third housing portions 14, 1 adjacent to the left and right along the front surface by two partitions 12, 13
It is divided into 5 and 16. The first storage section 14 is set to be waterproof (for example, JIS-C0920), the second storage section 15 is set to be drip-proof (for example, JIS-C0920), and is freely ventilated, and the third storage section 16 is free to be flooded. Ventilation is set freely. That is, the first, second, and third housing portions 14, 15, 16 are independent spaces having different waterproof levels.

Further, the housing case 11 includes a housing portion 14,
There are provided first, second, and third housing covers 17, 18, and 19, which can be opened and closed corresponding to ones 15 and 16, respectively. The housing covers 17, 18, and 19 are rotatably attached to the housing case 11 by hinges 21.
5, 16 can be independently opened and closed. It is to be noted that a gap closing means such as a packing is provided as necessary on one or both of the surfaces around the openings of the housing portions 14, 15, 16 and the housing covers 17, 18, 19.

The first housing 14 is suitable for use as an electronic equipment housing for housing electronic equipment. The second housing 15 is suitable for use as a cable connection housing for housing the cable connection. Third
The housing 16 is suitable as a battery housing for housing a battery. Here, the electronic device, the cable connection unit, and the battery are collectively called internal components.

In actual use, the electronic device is accommodated in the first accommodating portion 14 of the above-mentioned communication device housing, the cable accommodating portion is accommodated in the second accommodating portion 15, and the third accommodating portion 16 is accommodated.
House the battery. Thus, a communication device suspended from, for example, an overhead communication cable stretched between telephone poles is obtained.

According to the communication device, the housing cover 17,
By opening only necessary parts 18 and 19, it is possible to operate internal elements corresponding to the necessary parts, so that operability is improved. Further, since only a specific internal element can be operated without affecting other internal elements, high reliability can be obtained even after the operation of the internal element is performed.

FIG. 2 is a cross-sectional view of a communication device housing according to another embodiment of the present invention. In this case, a pressure adjusting hole 22 is provided in the partition wall 12 that separates the first housing portion 14 and the second housing portion 15. The pressure adjustment hole 22 reduces the pressure difference between the inside and outside of the housing and allows the first accommodation section 1
4 helps to prevent condensation. Preferably, the pressure adjusting hole 22 is provided with a gas permeable membrane.

In the above description, the internal space of the housing case is partitioned into three storage portions, but it may be partitioned into four or more storage portions. The housing cover may be provided on the housing case by means different from the hinge, or may be detachable from the housing case.

[0020]

As described above, according to the present invention,
A communication device housing excellent in operability and reliability can be provided.
In particular, since the inside of the housing case is partitioned into three housing portions having different waterproof levels by partition walls, and each housing portion is provided with a housing cover, the housing portions are made independent, so that operability is improved.

Further, when a pressure adjusting hole is provided in a partition partitioning the first housing portion and the second housing portion, a pressure difference between the inside and outside of the housing is reduced.
