Description

The present invention relates to an optical component storage tray, a multistage optical component storage box including the optical component storage tray, and a method of mounting the optical component on a printed circuit board using the optical component storage tray.

  In recent years, there has been a high demand for ultra-large capacity, ultra-long distance, ultra-high speed, and low cost for communication devices. To achieve this, signal processing (demultiplexing, Application of photonic network technology capable of branching and insertion (cross-connect) is being accelerated.

  By the way, the optical circuit unit (optical module, optical mounting printed circuit board, etc.) used in the photonic network is mounted with optical components that are connected to each other (optical connector connection and optical splice connection), and the quantity increases. There is a tendency.

  However, since the optical connector connection requires a large outer diameter of the connector, requires an adapter and a fixing part necessary for the connector connection, and requires a wide mounting area, an optical splice capable of reducing the connecting portion as disclosed in Patent Document 1 A connection is being used.

  Conventionally, a splicer (dedicated equipment) is used, and a fusion splice connection is often used in which the ends of the two optical fiber cores are discharged and fused. The sleeve is covered, and this is heated again in the splicer and thermally contracted to protect the connection portion.

Then, the tip of the optical fiber 87 is temporarily fixed to the notch 77 (temporary fixing means 73) of the sponge 75. This is to make it easier to grasp the optical fiber 87 during splice connection.

Work (3): The second stage component storage tray 11-2 is stacked on the component storage tray 11-1,
Work (4): After processing the optical component 83, as shown in FIG. 17B, the optical component 83 is held and stored in the holding means 53 of the component storage tray 11-2, and the optical fibers 89 and 91 are mounted. Temporarily housed in the storage tray-2, the tips of the optical fibers 89 and 91 are temporarily fixed to the notch 77 of the sponge 75.

  Work (5): The third stage component storage tray 11-3 is stacked on the component storage tray 11-2.

  Work (6): Next, after processing the optical component 85, the optical component 85 is held and stored in the holding means 53 of the component storage tray 11-3 as shown in FIG. The tip of the optical fiber 93 is temporarily stored in the notch 77 of the sponge 75 while temporarily stored in the component storage tray-3.

  Work (7): Then, as shown in FIG. 17 (d), the third-stage component storage tray 11-3 and the second-stage component storage tray 11-2 are expanded to form the third-stage component storage tray. A second-stage component storage tray 11-2 is placed on 11-3, and these are placed beside the first-stage component storage tray 11-1.

  Thereafter, as described above with reference to FIG. 16, the optical fiber 87 of the optical component 81 and the optical fiber 89 of the optical component 83 are pulled out to the splicer 7 and connected to the optical splice, and the optical fibers 87 and 89 are connected to the upper component storage tray 11-2. Form in.

  After the splice connection, if the optical component 85 or the like is mounted on a printed circuit board immediately without being carried, and the optical fibers 87 and 89 need not be taken out, the optical fibers 87 and 89 are inserted into the cuts 77 of the sponge 75. There is no need to temporarily fix.

  Work (8): Then, as shown in FIG. 17E, the second-stage component storage tray 11-2 is stacked on the first-stage component storage tray 11-1. As a result, the third-stage component storage tray 11-3 is arranged beside the component storage tray 11-2.

  Thereafter, the optical fiber 91 of the optical component 83 accommodated in the component accommodating tray 11-2 and the optical fiber 93 of the optical component 85 accommodated in the component accommodating tray 11-3 are pulled out to the splicer 7 to be optically spliced and pulled out. The optical fibers 91 and 93 are formed on the component storage tray 11-3.

  Work (9): Then, as shown in FIG. 17 (f), a third stage component storage tray 11-3 is stacked on the component storage tray 11-2 to form a multistage optical component storage box 79. The optical component 85 that is first mounted on the printed circuit board P is accommodated in the uppermost component accommodating tray 11-3.

  The optical fibers 87, 89, 91, and 93 are inserted through the gaps 29 between the component storage trays 11-1 to 11-3, respectively.

Work (10): Thereafter, as shown in FIG. 17G, first, the optical component 85 is mounted on the printed circuit board P using the multistage optical component storage box 79 that stores the optical components 81, 83, and 85. And
Work (11): The optical component 93 and the like are formed on the printed circuit board P as shown in FIG. 17 (h), and the next optical component 83 is mounted on the printed circuit board P from the second-stage component storage tray 11-2. And
Work (12): As shown in FIG. 17 (i), while forming the optical fibers 87, 89, etc. on the printed circuit board P, the last optical component 81 from the first-stage component storage tray 11-1 is applied to the printed circuit board P. The mounting operation of the optical components 81, 83, 85 on the printed circuit board P is completed.

Thus, when mounting the optical components 81, 83, 85 on the printed circuit board P, the optical components 81, 83, 85 are mounted on the component storage trays 11-1 to 11-3 for each of the component storage trays 11-1 to 11-3. held by the holding means 53 provided at the end of, if accommodated, accommodating state because such a easy layout and optical splice connection, Ru can der light splicing of the optical component itself. In addition, since the fiber drawing extra length can be shortened as compared with the conventional case, the forming area and the number of forming steps can be reduced.

  Since the holding means 53 and 59 are formed by adhering electrostatic-compatible sponges 61, 63, and 67 on the tray surface 21 with a double-sided tape or the like in accordance with the shape of the optical component, manufacturing is possible. The sponge is simple and low in cost, and can be prevented from being damaged by static electricity because it is a sponge that supports static electricity. Similarly, the temporary fixing means 73 is also formed by making cuts 77 in the electrostatic-compatible sponge 75 with a cutter or the like, and sticking these on the left and right sides of the side walls 17, 19 and the side walls 37, 39 with double-sided tape or the like. Therefore, the manufacturing is simple and the cost can be reduced, and the damage to the optical fiber can be prevented because the sponge is electrostatic.

  Then, while sequentially stacking the component storage trays 11-1 to 11-3, by forming the multistage optical component storage box 79 that realizes optical component storage simultaneously with the optical splice connection operation of the optical components, The trouble of housing the parts can be saved, and the troubles of the conventional example of FIG. 24, which is poor in handling property and leads to disconnection of the optical fiber and increase in mounting time, can be solved.

  Further, by temporarily fixing the optical fibers 87, 89, 91, 93 to the temporary fixing means 73, the optical fibers 87, 89, 91, 93 can be easily grasped at the time of splice connection, and workability is improved.

  Then, by performing the mounting operation of the optical components 81, 83, and 85 using the multistage optical component storage box 79 that stores the optical components 81, 83, and 85 in the mounting order, it is possible to reduce the forming area and the number of forming steps. In addition, the workability is remarkably improved as compared with the conventional example of FIG. 24, and it is possible to save the trouble of housing the parts after the splicing.

  In the embodiment, the multistage optical component storage box 79 is formed using the three component storage trays 11-1 to 11-3. However, the multistage optical component is used by using a plurality of the component storage trays 31 of FIG. A storage box may be formed, or a multistage optical component storage box may be formed using the component storage trays 11 and 31, and even when these multistage optical component storage boxes are used, Similar to the embodiment, the intended purpose can be achieved.

  In forming the multistage optical component storage box 79, the front and rear of the component storage trays 11-1 to 11-3 are alternately stacked. To improve workability, for example, paint is applied to the front side of the component storage tray 11. Etc. may be applied.

  Further, since the optical fiber is straight and tends to spread with a force to return the bend, there is a risk of jumping over the side walls 13, 15, 33, 35 of the component storage trays 11, 31.

Therefore, for example, as in FIG. 1 8, the convex portion for preventing jumping out of the optical fiber 87 to the inner surface of the side wall 13, 15 toward the (engagement portion) 95 inwardly projecting, also, as shown in FIG. 1 9, By providing a recess (locking portion) 97 for preventing the optical fiber 87 from popping out on the inner side surfaces of the side walls 13 and 15, there is an advantage that the mounting workability is further improved.
