Abstract

PROBLEM TO BE SOLVED: To provide an optical connector connecting panel that can be fully stored in a rack without changing the mounting position of a supporting body including the mounting angle in the rack for example. SOLUTION: Regardless of the position of the mounting angle in the rack 17, the sides 22b, 23b of the bolsters 22, 23 of the connecting panel 21 are shifted in the depth direction in accordance with the position of the mounting angle 20, with the sides 22b, 23b fixed on the sides 24a, 24b of the main body 24 of the connecting panel 21, and then, the front parts 22a, 23a of the bolsters 22, 23 are attached to the mounting angle 20. Consequently, the connecting panel 21 of the optical connector can be fully stored in the rack 17 independently of the position of the mounting angle 20.

In order to achieve the above object, the optical connector connection panel of the present invention is a box-type optical fiber core for accommodating an optical fiber core wire from which an end coating of an optical fiber cable is removed. In order to accommodate the wire processing unit main body and the optical fiber core wire processing unit main body in the rack in a drawn-out state, the front surface portion is attached to each of a pair of supports standing upright in the rack, and the side surface portion and the bottom surface portion are optical. A pair of receiving fittings for supporting the side surface portion and the bottom surface portion of the fiber core wire processing unit main body, and a fixing means for fixing the optical fiber core wire processing unit and the receiving metal fitting whose position is adjusted in the depth direction in the rack. Be prepared.

In addition to the above structure, the optical connector connection panel of the present invention is provided with a screw through a screw hole formed in the side surface of the main body of the optical fiber core processing portion and a through hole formed in the side surface of the receiving metal fitting. It is preferably fixed by the fixing means.

In addition to the above structure, the optical connector connection panel of the present invention has a plurality of screw holes horizontally provided at a predetermined pitch, and the through holes may be slits extending horizontally.

According to the present invention, regardless of the position of the mount angle in the rack, the side surface of the bracket of the optical connector connection panel is shifted in the depth direction according to the position of the mount angle, and then the optical fiber core wire is moved. By fixing the side surface of the bracket to the side surface of the processing unit and fixing the front surface of the bracket of the optical connector connection panel to the mount angle, the optical connector connection panel can be installed in the rack regardless of the mounting position of the mount angle. Can be housed completely in a drawer.

Are fixed by screws 25, but the fixing position is not limited to the position shown in the figure, and the panel main body 24
Is displaced in the depth direction with respect to the metal fittings 22 and 23, and is fixed by a screw 25 so that the through hole 22d and the screw hole 24c are aligned with each other. It can be fixed by shifting it to an arbitrary position with respect to 23b.

The accommodation state of the optical fiber core wire 3 at the end portion of the optical fiber cable 2 in the optical connector connection panel 21 is the same as that of the conventional example, and therefore will be omitted.

FIG. 5 is a schematic side view showing a state where the optical connector connection panel shown in FIGS. 1A to 1C is attached to a rack.

Like the rack 17 shown in FIG. 10, a pair of mount angles 20 (one of which is hidden on the back side of the drawing) is arranged near the front frame of the rack 17. In this case, Shelf board 2 protruding from 17
By shifting the processing unit main body 21a in the depth direction of the rack 17 by the length of 6 and then screwing it, the shelf plate 26 can be housed without protruding from the rack 17.

FIG. 6 (a) is a sectional view when a conventional optical connector connection panel is attached to the front wall of the wall (support) of the double wall structure, and FIG. 6 (b) is shown in FIG. 6 (a). ) Is a perspective sectional view of FIG. FIG. 7A is a cross-sectional view when the optical connector connection panel of the present invention is attached to the front wall of the double-wall structure (support), and FIG. 7B is the sectional view of FIG. It is a perspective sectional view.

It can be seen from FIGS. 6A and 6B that the shelf plate 12 is protruding from the front wall 28.

However, by using the optical connector connection panel of the present invention, after fixing the panel body 24 in the depth direction with respect to the metal fittings 22, 23 as shown in FIGS. By attaching to the front side wall 28, the shelf plate 26 is pulled in further than the front side wall 28 and does not stick out from the wall 28. In addition, 29 shows the back side wall.

In the above, no matter where the support such as the mount angle is located in the rack, the metal fittings of the optical connector connecting panel are shifted in the depth direction according to the position of the support so that the side surface is the side surface of the panel body. After fixing the optical connector connection panel to the support, the optical connector connecting panel can be completely housed in the rack regardless of the position of the support.

Although the through holes and the screw holes are formed at the predetermined pitches P1 and P2 in the present embodiment,
The present invention is not limited to this, and the through hole of the receiving metal fitting may have an elongated slit shape in which the through hole is connected in the horizontal direction. In this case, the position of the panel body in the depth direction can be continuously changed. Further, the fixing means for fixing the bracket and the panel main body of the optical fiber core wire processing section is not limited to the screw, and other means can be used as long as they can be fixed,
For example, it may be a pin. In the case of the pin, the hole provided in the side surface of the panel body does not necessarily need to be a screw hole, and may be a through hole. Although only one optical connector connection panel is accommodated in the rack 17 shown in FIG. 5, it goes without saying that a plurality of optical connector connection panels may be accommodated in a drawer form.

In summary, according to the present invention, the following excellent effects are exhibited.

It is possible to provide an optical connector connection panel that can be completely housed in a rack without changing the mounting position of a support such as a mount angle in the rack.
