Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desktop case for electronic communication equipment suitable for outdoor installation.

[0002]

2. Description of the Related Art In a conventional case of this type, a method of closing a gap between a cover and a main body with rubber packing or the like is adopted.
Also, no measures were taken against environmental conditions.

[0003]

However, in recent years, outdoor type electronic equipment is severely required to meet environmental conditions and waterproof performance, and the conventional structure as described above cannot meet these requirements.

It is an object of the present invention to provide an electronic communication device which can simultaneously realize environmental resistance and waterproofness.

[0005]

In order to achieve the above object, according to the present invention, a box-shaped main body which accommodates a subrack in which a plurality of packages are removably mounted and has an opening on at least one end face thereof. And a cover attached to the main body portion with the bent portions on four sides with the bent portions facing the main body portion, and in the direction perpendicular to the end surface around the opening of the end surface of the main body portion. A projecting piece of equal height, which is located inside the bent portion of the cover, is provided, and on the inner surface of the cover, a first flange and a second flange having a height lower than that of the first flange are provided on the bottom side. When the cover is attached to the main body portion, a U-shaped member in which an elastic body that is in pressure contact with the projecting piece is embedded when the cover is attached to the main body portion is attached. To contact with the first flange A structure, wherein a conductive member is attached (the first configuration).

In addition, in the desktop casing of the electronic communication device having the above-mentioned first structure, a connecting plate having a cable support for sandwiching the subrack and arranging a cable from the subrack is attached to the cover. (Second configuration).

Further, in the desktop casing of the electronic communication device having the above-mentioned first structure, a tongue-shaped plate is provided at the bottom of the subrack, and the tongue-shaped plate is slidably guided to the main body. A rail member that engages with is provided (third configuration).

In addition, in the desktop case of the electronic communication device having the above-mentioned first structure, the optical cable holding package, which is made into a block for each package unit, is detachably attached to the subrack (fourth structure). Configuration).

[0009]

In the case of the first configuration, water drops such as rainwater are cut off even by the bent portion of the cover and do not enter much inside. Further, the water droplets that have entered a little inside are completely cut off by the projecting piece that presses against the elastic body in the U-shaped member, and does not enter the main body. On the other hand, the conductive member provided on the main body contacts the first flange of the U-shaped member. Therefore, waterproofness and environment resistance can be realized at the same time.

In the case of the second configuration, the cable from the subrack can be arranged easily and surely by the cable support provided on the connecting plate.

In the case of the third structure, since the subrack is guided by the rail member, the mounting is easy. Further, since the subrack is attached by engaging the tongue-shaped plate with the rail member, stable mounting can be realized.

In the case of the fourth structure, an optical cable holding package, which is made into a block for each unit of the package, is mounted on the subrack so that the optical cable to the optical module is mounted on the package. Connection work becomes convenient.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a partially cutaway perspective view of a desktop casing of a telecommunications device of this embodiment, FIG. 2 is an exploded perspective view of the same, and FIG. 3 is a perspective view showing the same appearance. In FIG. 1, 1 is a subrack 4 A box-shaped main body portion 2 and 3 for accommodating is a front cover and a rear cover attached to the front end and the rear end of the main body portion 1, respectively. These constitute the desktop case 40. On the four sides of the front cover 2 and the rear cover 3, a bent portion 5 and a bent portion 6 protruding toward the main body 1 are provided.
Are provided respectively.

An opening 7 is provided on the end face 1a (see FIG. 4) at the front end of the main body 1, and the opening 7 is located around the opening 7 and protrudes in the direction perpendicular to the end face 1a and is located inside the bending portion 5. A protruding piece 8 having a uniform height is provided. A conductive member 9 is attached near the front end of the main body 1. further,
A pair of rail members 10, 10 for slidingly guiding the subrack 4 are attached to the bottom of the main body 1.

On the rear end side of the main body 1 as well as on the front end side,
An opening 11 and a projecting piece 12 are provided on the end face 1b, and a conductive member 13 is attached.

On the inner surface of the front cover 2, the first flange 1
5 and a second flange 16 having a height lower than that of the first flange 15 are connected to a bottom side 17 (see FIG. 4), and a U-shaped member 14 is attached with the bottom side 17 in contact. An elastic body 18 such as rubber is embedded in the U-shaped member 14. Further, a connecting plate 19 having a shape capable of holding the subrack 4 mounted and housed in the main body 1 is attached to the inner surface of the front cover 2 as described later.
A cable support 20 is attached to 9.

The subrack 4 has a plurality of packages 21.
The optical cable holding package 22 is mounted so that it can be inserted / removed and is blocked for each unit of the package 21. The optical cable holding package 22 includes a plurality of optical cables 23, as shown in detail in FIG. 5 (FIG. 5A is a side view, FIG. 5B is a plan view, and FIG. 5C is a front view). The cable holder 24 holds the optical cable 23 in a loop at two upper and lower positions, and both ends of the optical cable 23 are led out to the front plate 25. The width of the front plate 25 is the same as the width of the front plate of the package 21.

A pair of tongue-shaped plates 26 are attached to the bottom of the subrack 4, and the tongue-shaped plates 26 are mounted by guiding the subrack 4 to the rail member 10 in the main body 1. When it is locked to the locking portion 10a of the rail member 10, it engages with the slit 27 at the end of the rail member 10. Also,
When attaching the front cover 2 to the subrack mounting plate, both side surfaces of the subrack 4 near the backboard 28 are connected to the connecting plate 19.
