Description

Tray to store loaded optical codes

The present invention relates to a tray capable of storing a portion of an optical cord for an optical jumper for connecting between systems of an optical communication equipment.

In general, optical communication devices using optical fibers are connected to an optical fiber cable to receive or transmit an optical signal transmitted from an external optical path. It is also connected via optical codes to exchange necessary information between optical communication systems. The optical cord has an optical coupler coupled at both ends thereof and is connected to each optical communication system through the optical coupler. Such optical cords use ready-made optical cords having a length of about 10 m without being adjusted to an appropriate length in consideration of the separation distance between systems of optical communication equipment.

Such optical cords are generally used for optical jumping to interconnect optical signals between optical systems, so that when the separation distance between optical communication systems is short, the length of the optical cord is unnecessarily long, leaving the part of the optical cord left outside.

As such, when the optical cord is exposed to the outside, the optical cord is not good in appearance and often occurs when the optical cord is stepped on or bent by the passerby and the optical cord is broken. Since the optical cords are connected to the optical communication system by several dozens, the optical cords are entangled with each other, which makes it difficult to process the codes. There has been discomfort.

Therefore, the present invention is drawn to solve such a conventional problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide a tray for storing an optical cord which can simplify the path of an optical cord while maintaining the optical transmission characteristics of the optical cord during path processing or distribution of the optical cord, and further clarifies the classification of the optical cord.

According to the present invention, when the optical cord connected to the optical communication system through the optical connector is entered into the gate, the optical cord mounted on the circumferential surface of the mandrel is wound, and the optical cord is inserted into and discharged from the gate, and the tray is accommodated in the casing. It can protect the sheathed optical cord from being exposed to the outside and can arrange the optical cord concisely, and can effectively process the path by adjusting the length of the sheath according to the number of times the optical cord is wound on the mandrel.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, Figure 1 is a perspective view showing a tray in which the optical code storage mandrel according to the present invention is installed, Figure 2 is a plan view of the tray shown in Figure 1, reference numeral 10 in the drawing is a multi-stage tray Many of them are stacked on top of each other in a mold. Reference numeral 11 is a partition plate for partitioning the surface of the tray so as to be partitioned into a predetermined area, 12 is a shaft for rotatably coupling the tray 10 in a casing (not shown), the tray 10 When rotating or withdrawing the) is configured. And reference numeral 11a is a guide plate extending from the partition plate 11 on the upper part spaced apart from the bottom of the tray, 20 is detachable to the base plate 10a of the tray 10 partitioned by the partition plate (11). The mandrel is possibly attached. Reference numeral 11b denotes an auxiliary partition plate that is partitioned between the partition plate 11 and the partition plate 11 again.

The above components will be described in more detail. The tray 10 is stacked in multiple stages by the bearing part 12. The bearing part 12 is not shown in the drawing but is rotatably coupled to and supported by the inner wall of the casing. In the tray 10, the gate 13 is disposed by cutting a predetermined space at one corner of the tray 10, preferably in the corner portion adjacent to the ledge 12. The gate 13 provides the function of the entrance and exit of the optical cord 1 into or out of the tray 10. The tray 10 constitutes a substantially plate-like body, and the front cover and the side cover are formed to extend vertically from the base plate 10a. The base plate 10a is chamfered with a constant radius of curvature, and at the position where the mandrel 20 is disposed, as shown in FIGS. 3A and 3B, a snap pit 10b protruding upward is disposed and the mandrel ( It is fastened to the fastening hole 20a formed in the bottom surface of 20. The reason for chamfering the edge of the base plate 10a is that the tray 10 is not caught by the inner surface of the casing when the tray 10 rotates about the center 12.

The mandrel 20 has a circumference around the circumference at the upper end of the circumferential surface 21 and the circumferential surface 21 having a height similar to the height of the sidewall or the partition plate 11 as shown in FIGS. 3A and 3B. Branched fences 22 disposed in the chamber. The fence 22 provides a function of preventing the optical cord 1 wound several times on the circumferential surface of the mandrel 20 from being released beyond a predetermined radius from the circumferential surface.

An example of storing the optical code in the tray according to the present invention as described above with reference to the accompanying drawings as follows.

First, as shown in FIG. 1, when the tray is rotated forward with respect to the stem 12, the tray is rotated from the casing and exposed to the outside. The optical cord 1 is inserted between the guide plates 11a arranged in the plane of the exposed tray, wound around the circumferential surface of the mandrel 20 with a desired number of times, and the optical cord 1 wound on the mandrel 20 is gated. ) To be discharged. At this time, the optical cord 1 tends to be released to a somewhat larger diameter on the circumferential surface 21 of the mandrel 20, but is not released by a fence 22 more than a predetermined radius. In this manner, a plurality of optical cords 1 are overlapped or wound around each mandrel on each mandrel 20 arranged on the tray 10.

In addition, as a modification of the mandrel 20 described above, as illustrated in FIGS. 3A and 3B, the mandrel 20 may be implemented in a stacked form in one to four stages. In this case, each of the mandrel 20 is used to assemble with each other through the snap fit 10b and the fastening hole 20a as described above.

When the mandrel 20 is installed in a multi-step type as described above, a plurality of optical cords 1 can be wound and stored independently on each of the stacked mandrels 20 so that the optical cord 1 can be newly rearranged or routed. New changes make it easier to find the optical code and are very effective in optimizing the path of the optical code.

As described above, the present invention minimizes the length of the optical cord exposed to the outside by storing the female part of the optical cord 1 used for the optical jumper in the tray 10 by using the tray 1. The optical cords can be placed in the optimal path by wrapping multiple optical cords in a mandrel and storing them in separate trays, providing a clearer and faster identification of the entangled optical cords. Will be done.
