Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber connection trays, and particularly to a novel high-density optical fiber connection tray. Background Art

[0002] With the continuous development of optical communication technology, at present, the FTTX network construction mode has become the main battlefield for the business competition of the three major domestic operators. Looking at the medium and long term, the FTTB mode is only a transitional access mode for broadband access, and FTTH will be the ultimate development direction in the future. According to the development goals of the Ministry of Industry and Information Technology, the average broadband access capacity in cities should reach 8M in the near future, and the average broadband access capacity in rural areas should reach 2M. It can be seen that the optical fiber broadband industry has become one of the fastest-growing and largest-growing industries in the current information industry. Optical fiber distribution frames and outdoor optical cable cross-connect boxes are optical communication terminal devices widely used in optical fiber fusion splicing, wiring, line adjustment, and testing between optical cables in the optical fiber access network. They are the hubs for signal transmission, scheduling, and conversion between optical signal transceiver devices, and have functions such as optical signal scheduling and switching. In a conventional optical fiber distribution frame, the terminal part and the fusion splicing part are installed separately, or the terminal part and the fusion splicing part are located at the upper and lower positions of the same module, which not only occupies space but also is inconvenient for management.

[0003] In this regard, Chinese Patent Publication No. CN201673294U discloses "an integrated optical fiber fusion and distribution tray, including a fusion splicing base plate. The fusion splicing base plate has a bottom plate and surrounding wall plates. On the left and right side wall plates of the fusion splicing base plate, there are respectively extended slot ribs. An arc-shaped groove for positioning is provided on the slot rib. On the front wall plate of the fusion splicing base plate, there are a plurality of obliquely arranged adapter slots and vertically arranged vertical slots at both ends thereof. The characteristics are that: the bottom plate of the fusion splicing base plate is composed of an upper bottom plate and a lower bottom plate connected by an arc transition. The adapter slots are located on the lower bottom plate. On the left and right sides of the upper bottom plate, there are respectively symmetric reinforcing arc plates, and on the front and rear sides, there are reinforcing baffle plates. On the inner and outer sides of the two reinforcing arc plates, there are respectively upper fiber retaining plates. On the inner sides of the two reinforcing baffle plates, there are upper fiber retaining plates. On the inner sides of the two reinforcing baffle plates where the upper bottom plate is located, there are respectively more than two optical splitter fixing buckles and more than two branch guide posts, and on the outer sides, there are respectively more than two tail fiber retaining hooks and more than two bare fiber protection tube slots".

[0004] The above-mentioned patent fuses two external optical fiber cables on a splicing tray. This method is suitable for the connection of a single optical fiber. However, when it is necessary to connect to an external device, since there are multiple optical fibers in the cable at the access end of the device, it is necessary to splice all the optical fibers in the cable one by one. This not only involves a large amount of work, but also wiring errors may occur in case of operation mistakes. Moreover, after the external optical fiber cables are spliced, the butt joints of the wires are generally fixed by double-sided tape. However, the adhesiveness of the double-sided tape is easily affected by temperature, resulting in insufficient adhesive force, which may cause the wire joints of the optical fiber cables to fall off from the splicing tray. In view of this, the present utility model proposes a new type of high-density optical fiber connection tray.

A plurality of optical fiber fusion splicing cards 45 for clamping the optical fiber 5 and the external optical fiber for fusion splicing are arranged at the other end of the top of the mounting plate 41. The plurality of optical fiber fusion splicing cards 45 are arranged in an array on the top of the mounting plate 41; by arranging the LC double adapters 3 and the optical fiber fusion splicing cards 45 in an array, a high-density optical fiber path is realized, meeting the requirements of a large amount of data exchange. The optical fiber fusion splicing cards also facilitate the modification of the optical fiber line layout by maintenance personnel in the later stage.

[0028] It is directly connected to the external device through the MPO connector 44, without connecting through the fusion splicing method of the optical fiber 5, reducing the manual labor amount and avoiding the problem of wiring errors at the same time; the optical fiber 5 and the external optical fiber are clamped and fused through the optical fiber fusion splicing card 45, without using an adhesive to fix the optical fiber 5 and the external optical fiber, so that the optical fiber 5 and the external optical fiber are stably installed on the mounting plate 41 after fusion splicing. The whole structure can realize two wiring methods, meeting the wiring work in different scenarios, and having strong versatility.

Winding plates 21 for winding the optical fiber 5 are fixedly connected to both ends inside the movable disk 2. A wire passing groove 22 for leading out the optical fiber 5 inside the chassis 1 is formed in the middle of the movable disk 2. A wire guiding plate 24 is fixedly connected to one end of the wire passing groove 22. The winding bases 11 can wind the optical fiber 5 to avoid the problem of multiple optical fibers 5 being wound around each other. The winding plates 21 can wind the surplus optical fiber 5 during wiring to avoid the optical fibers 5 being wound around each other.

[0030] Furthermore, the MPO connector 44 includes an MPO adapter 441. The input end of the MPO adapter 441 is connected to a plurality of LC duplex adapters 3 through a plurality of optical fibers 5.
