However, when the above-mentioned conventional splice shelf is used for connecting the optical fiber cable 10 (hereinafter referred to as an optical cable), the optical cable is hardly bent due to its structure, and has a higher curvature than an ordinary metal cable. Therefore, the space cannot be used unless the space in front of the panel 3, which is the cable connection surface of the splice shelf, is made large to secure the curvature of the optical cable. for that reason,
When an optical cable is connected, a cabinet having a large distance L from the equipment mounting column 6 of the cabinet 8 to the front of the cabinet has been used. Therefore, compared to conventional cabinets, the overall depth dimension was larger and larger, and the installation space required a larger space,
Manufacturing costs were also high.

Accordingly, an object of the present invention is to provide a splice shelf that can be connected to an optical cable without increasing the depth of the cabinet.

[0005]

In order to solve the above-mentioned problems, a first aspect of the present invention is to dispose a panel provided with a cable connection terminal on a front surface thereof, and to protrude rack mount fittings at left and right ends thereof. A splice shelf provided with a device installation space in a back portion, wherein the rack mounting bracket is provided so as to protrude forward from the panel surface.

According to a second aspect of the present invention, in the first aspect of the invention, the amount of protrusion of the rack mount fitting from the panel surface can be changed.

According to a third aspect of the present invention, in the first aspect of the present invention, the left and right rack mount brackets are integrally formed on a frame surrounding the equipment installation space, and the panel is movable back and forth inside the frame. You.

Embodiments of the present invention will be described below in detail with reference to the drawings. 1A and 1B show a first embodiment of a splice shelf according to the present invention, wherein FIG. 1A is a front view, and FIG. 1B is a front view installed in a cabinet.
The splice shelf 1 has a panel 3 provided with a plurality of cable connection terminals 4 for connecting an optical cable connector such as an SC connector on the front side of a U-shaped frame 2 having an open front. A bottom plate 5 is provided on the lower surface of the frame 2 to form a space 14 for installing equipment.

At the front end of the left and right side plates 2a of the frame 2, a rack mount fitting 6 for mounting the splice shelf 1 to the equipment mounting support 9 on the cabinet 8 side is provided. The rack mount fitting 6 is formed of an L-shaped metal plate, has a screw insertion hole 6a formed on the front surface side, is fixed to the side plate 2a, inserts a screw into the screw insertion hole 6a, and attaches the rack mount fitting 6 to a device. The splice shelf is installed in the cabinet 8 by being fastened to the support 9. The panel 3 is disposed inside the frame 2, the right and left sides are fixed to the frame 2 by angle members 7, and the rack mount fitting 6 projects forward from the panel 3.

By protruding the rack mount fitting 6 forward from the panel 3 as described above, a large space in the cabinet at the front of the panel can be obtained when the splice shelf 1 is installed in the cabinet. Without increasing the distance L to the front of the cabinet 8,
That is, the optical cable 10 can be connected to the connection terminal 4 without increasing the depth of the cabinet. Therefore, the depth can be reduced and the cost can be reduced as compared with the conventional optical cable connection cabinet.

FIG. 2 shows a second embodiment of the present invention.
The splice shelf 1 has a device installation space formed of a rectangular box body 11 and is hermetically sealed, and has rack mount fittings 6 fastened to its left and right side surfaces by screws. Rack mount bracket 6
In the portion to be fastened to the box body 11, two connection holes 6 b are provided in the rack mount 6 in the vertical direction, and screws 15 are inserted and fastened. Then, three sets of the connection holes 6b are formed in the front-rear direction, and the rack mount fitting 6 is connected to the three sets of the connection holes 6b,
By selectively using 6b, 6b, it is possible to change the mounting position in three stages in the front-rear direction.

As described above, the space of the front face of the panel may be changed by moving the rack mount fitting 6 in the front-rear direction, and the panel having the same curvature may be moved in the depth direction in accordance with the type of the optical cable. Space can be increased.

FIG. 3 shows a third embodiment of the present invention.
The rack mount 6 is fixed to the frontmost portion of the frame 2, and the panel 3 can move back and forth inside the frame 2. Inside the side plate 2a of the frame 2, L-shaped members 12 for fixing the panel at left-right symmetrical positions are installed at three places in the front-rear direction, and the panel 3 can move inside the frame 2 in three steps in the front-rear direction. It has become. To fix the panel, a screw hole is provided in the L-shaped member 12, a screw insertion hole 12a is provided in a corresponding position of the panel 3, and the panel is fastened with a screw. As described above, the panel may be movable by fixing the rack mount bracket, and the space in front of the panel can be changed even after the splice shelf is installed in the cabin.

Further, as shown in FIG. 4, a vertical cut 13 may be provided in the side plate, and both ends of the panel may be inserted and supported in the cut 13. This way, panel 3
Since a fixing tool such as a screw is not required for fixing the panel, the operation of changing the position of the panel can be easily performed.

In the above embodiment, the position of the rack mount bracket or the panel can be changed in three steps, but may be changed in more steps.
You may make it slide and change it steplessly. Others
The shape and configuration of each part can be appropriately changed and embodied without departing from the spirit of the present invention.

[0016]

As described above in detail, according to the first aspect of the present invention, since the rack mounting bracket is projected forward of the panel for connecting the cable, the cabinet front dimension can be increased without increasing the depth of the cabinet. A large space can be taken in the cabinet, and an optical fiber cable can be connected with a required curvature. Therefore, the depth can be reduced and the cost can be reduced as compared with the conventional optical fiber cable connection cabinet.

According to the second or third aspect of the present invention, since the panel position can be moved in the front-rear direction, the space at the front of the panel can be changed according to the cable to be connected.
