Abstract
Description
Technical Field
[0001] This utility model belongs to the field of optical fiber data communication technology, and specifically relates to an integrated fusion splicing optical fiber distribution unit. Background Technology
[0002] Fiber optic distribution frames are important supporting equipment in optical transmission systems. They are mainly used for fiber optic splicing at optical cable terminals, adjusting optical connectors, storing excess pigtails, and protecting optical cables.
[0003] Currently, traditional 19-inch fiber optic patch panels placed in cabinets typically do not contain fiber storage cylinders. However, this design still has some problems and drawbacks in practical applications: 1) Limitations of traditional design: The design concept of traditional fiber optic patch panels mainly focuses on the realization of functions, while ignoring the overall integrity of the equipment and space optimization.
[0004] 2) Complex cabling: The split design requires additional cabling operations to connect the optical fiber between the fiber storage canister and the patch panel, which increases the complexity and workload of the cabling and can also easily lead to fiber optic mess, affecting the neatness and aesthetics of the cabling.
[0005] 3) Inconvenient maintenance: During maintenance, the fiber storage cylinder and patch panel need to be operated separately, which increases the difficulty and time cost of maintenance;
[0006] 4) Signal transmission loss: Because optical fibers need to be bent and transitioned multiple times during the connection process, signal transmission loss may increase, affecting communication quality and causing problems. Utility Model Content
[0007] The purpose of this invention is to solve the problems of large space occupation of existing fiber optic distribution frames and fiber storage cylinders and the complex wiring when connecting the two, and to provide a fiber optic distribution unit that integrates fusion splicing and splicing, which reduces the space occupied by the fiber optic distribution frame without affecting the wiring, and is designed as an integral structure with the fiber storage cylinder.
[0008] To achieve the above objectives, this utility model adopts the following technical solution: a fiber optic distribution unit integrating fusion splicing and splicing, comprising a distribution unit body, the distribution unit body being divided into a fiber winding area on the left and a fiber optic fusion splicing area on the right. A fiber storage cylinder for storing excess fiber patch cords is horizontally arranged within the fiber winding area, and multiple integrated trays are evenly distributed longitudinally within the fiber optic fusion splicing area. Each integrated tray contains a lower fiber holding area and an upper fiber winding area. Vertical fixing posts are symmetrically fixed on both sides of the lower fiber holding area, and the upper end face of the fixing posts contacts the bottom plate of the upper fiber winding area. The upper fiber winding area… The center of the structure has a fiber optic protection tube placement area, and the left and right ends are symmetrically equipped with inner and outer arc-shaped wire clamping devices, while the front and rear ends are symmetrically equipped with inner and outer straight wire clamping devices. The arc-shaped wire clamping devices and straight wire clamping devices located between the inner and outer layers together form the fiber optic cable routing channel. The upper fiber winding area at the rear straight wire clamping device has upper and lower fiber insertion ports on its bottom plate, and the lower fiber holding area and the upper fiber winding area are connected through the upper and lower fiber insertion ports. Fiber insertion outlets are provided on both sides of the upper fiber winding area corresponding to the front straight wire clamping device, and the optical fibers passing through the fiber insertion outlets are connected to the flange fiber outlets evenly distributed at the front of the integrated tray.
[0009] Furthermore, both the inner and outer arc-shaped wire clamping devices are composed of an inner arc-shaped plate and a circular arc-shaped wire clamping piece connected together and vertically fixed to the bottom of the upper layer winding area, with the circular arc-shaped wire clamping piece vertically connected to the upper surface of the inner arc-shaped plate; the inner arc-shaped wire clamping device is composed of an inner arc-shaped plate connected to a circular arc-shaped wire clamping piece on the outside, and the outer arc-shaped wire clamping device is composed of multiple circular arc-shaped wire clamping pieces evenly distributed inside and outside the inner arc-shaped plate.
[0010] Furthermore, both the inner and outer straight plate wire clamping devices are composed of a straight plate vertically fixed to the bottom of the upper fiber winding area and a rounded wire clamping piece connected together, with the rounded wire clamping piece connected vertically to the upper surface of the straight plate in the direction of the inner direction of the upper fiber winding area.
[0011] Furthermore, the integrated tray is also equipped with adapters for connecting fiber optic connectors, including SC, LC, and FC types.
[0012] Furthermore, each of the integrated trays is slidably connected to the fiber optic splicing area of the wiring unit body in the horizontal direction via sliding guide rails on both sides, wherein the sliding guide rails are U-shaped groove guide rails.
[0013] Furthermore, excess optical fibers in the integrated tray pass through the side of the upper fiber winding area and connect to the fiber storage cylinder.
[0014] The beneficial effects of this utility model are:
[0015] 1) In this utility model device, the fiber storage cylinder and the integrated tray are connected by internal optical fiber to form a complete optical fiber management system. The optical cable is spliced through the integrated tray, and after being wound from the fiber storage cylinder through connectors and optical fiber patch cords, it is connected to external equipment. Compared with the traditional optical fiber patch panel, it not only reduces the size of the integrated tray, but also makes it possible to accommodate patch panels and fiber storage cylinders at the same time in the conventional 19-inch size.
[0016] 2) This utility model device solves the problems of traditional fiber optic distribution frames in terms of space utilization, cabling complexity, and maintenance convenience. Through integrated design, it can simultaneously improve the compatibility and intelligence level of the equipment to meet the needs of modern fiber optic communication systems for efficient and flexible cabling. The fiber storage tube can protect the optical fiber and prevent it from being damaged by excessive bending or pulling, ensuring the integrity and transmission performance of the optical fiber. On the other hand, it facilitates management and maintenance, making the fiber optic cabling more regular and facilitating the connection, adjustment, and maintenance of the optical fiber.
[0017] 3) The device of this utility model is designed with an integrated tray with two internal layers. Compared with conventional trays, the capacity remains the same, but the size is smaller. Attached Figure Description

Vertical fixing columns 5 are symmetrically fixed on the left and right sides of the lower fiber-containing area 301, and the upper end face of the fixing column 5 is in contact with the bottom plate of the upper fiber-winding area 302. The fixing column 5 is used to support the bottom plate of the upper fiber-winding area 302 and to provide fiber-containing cavities and cable routing channels for the lower fiber-containing area 301.
[0026] The upper fiber winding area 302 has a fiber optic protection tube placement area 6 in the middle, and two inner and outer arc-shaped wire clamping devices 7 are symmetrically connected to the left and right ends, and two inner and outer straight wire clamping devices 8 are symmetrically connected to the front and rear ends.

[0027] Both the inner and outer arc-shaped wire clamping devices 7 are composed of an inner arc-shaped plate and a round-head wire clamping piece that are vertically fixed to the bottom of the upper winding area 302. The round-head wire clamping piece is vertically connected to the upper surface of the inner arc-shaped plate. The inner arc-shaped wire clamping device 7 is composed of an inner arc-shaped plate connected to a round-head wire clamping piece on the outside. The outer arc-shaped wire clamping device 7 is composed of multiple round-head wire clamping pieces that are evenly distributed inside and outside the inner arc-shaped plate.
[0028] Both the inner and outer straight plate wire clamping devices 8 are composed of a straight plate vertically fixed to the bottom of the upper fiber winding area 302 and a rounded head wire clamping piece connected together.
