Description

Technical Field

[0001] This application relates to the technical field of gateway devices, and particularly to an optical fiber panel bottom shell and an optical fiber panel. Background Art

[0002] At present, indoor optical fiber panels can be used for surface mounting or concealed mounting of optical fibers; among them, both surface mounting and concealed mounting require coiling of optical fibers.

[0003] In some related technologies, in order to reduce the space occupied by the fiber coiling structure of the optical fiber panel and to coil a certain length of optical fiber, the coiling radius of its general coiling structure is relatively small, and the optical fiber is coiled into multiple turns so that the space occupied by the coiling structure in the indoor optical fiber panel is less. This results in a relatively small bending radius when the optical fiber is coiled, and a small bending radius has a greater impact on the optical index.

[0004] Among them, the fused and unfused optical fibers share a coiling structure. The disadvantage after fusion is that the heat shrinkable tube after fusion needs to be placed at a fixed position above the bottom shell. Since the size of the outer shell is 86mm * 86mm, the bending radius is affected when the optical fiber exits, and the bending radius after coiling is also relatively small.

[0005] In addition, the surface-mounted and concealed optical fibers have 4 routing paths for surface mounting and 1 path for concealed mounting in the optical fiber panel. During the coiling process, it is necessary to be compatible with the routing and bending radius of each path, resulting in a relatively large design difficulty. Summary of the Utility Model

[0043] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0044] The influence on optical indexes can be understood as follows:

[0045] The change in the bending angle of the optical fiber will directly affect the optical properties of the optical fiber, such as the light intensity and bandwidth. When the bending angle of the optical fiber reaches a certain degree, the optical signal will leak out from the core layer, resulting in the loss of light intensity, thereby affecting the transmission distance and transmission quality of the optical signal. During the bending process of the optical fiber, the change in the bending radius will also have an impact on the optical properties. When the bending radius of the optical fiber is too small, there will be a large loss of light intensity and bandwidth attenuation. At the same time, the change in the bending radius will cause mode coupling of the optical fiber, thereby affecting the optical signal quality.

[0046] In actual use, the following problems exist:

[0047] First, in order to reduce the space occupied by the fiber coiling structure of the optical fiber panel and be able to coil a certain length of optical fiber, the coiling radius of its general fiber coiling structure is relatively small, and the optical fiber is coiled into multiple turns, so that the space occupied by the fiber coiling structure in the indoor optical fiber panel is relatively small. This results in a small bending radius when the optical fiber is coiled, and a small bending radius has a greater impact on the optical indexes.

[0048] Second, the fused and unfused optical fibers share a fiber coiling structure. The disadvantage after fusion is that the heat-shrinkable tube after fusion needs to be placed at a fixed position above the bottom shell. Since the size of the outer shell is 86mm * 86mm, the bending radius is affected when the optical fiber exits, and the bending radius after coiling is also small.

[0049] Thirdly, for surface-mounted and concealed optical fibers, there are 4 routing paths for surface-mounted fibers in the fiber optic panel and 1 routing path for concealed fibers. During the fiber coiling process, it is necessary to be compatible with the routing and bending radius of each path, resulting in greater design difficulty.

[0050] The following will explain the above three points in detail and hierarchically:

[0051] The following vertical sides are Figure 3 and Figure 5 The vertical side label H1 in Figure 4 and the horizontal side label H2. The vertical and horizontal sides in the subsequent appendix

[0052] In the first aspect, for the first point, a bottom shell of a fiber optic panel is provided to solve the problem in the related art that in order to reduce the space occupation of the fiber coiling structure of the fiber optic panel, the coiling radius of the fiber coiling structure is relatively small, resulting in a relatively small bending radius of the optical fiber and a greater impact on the optical index.

[0053] Refer to Figures 3 to 6 , a bottom shell of a fiber optic panel, which includes:

[0054] A fiber coiling structure 1, which is arranged on the bottom wall of the bottom shell of the fiber optic panel and includes a first part and a second part arranged at intervals along the direction of the vertical side;

[0055] The first part includes a first arc-shaped guiding edge 100 and a second arc-shaped guiding edge 101 arranged at intervals along the direction of the horizontal side; the second part includes a connected third arc-shaped guiding edge 103 and a first straight guiding edge 104, and the first straight guiding edge 104 is inclined, and the top of the end far from the third arc-shaped guiding edge 103 extends towards the second arc-shaped guiding edge 101.

[0056] The effects brought by the above structure can be explained with reference to Figure 4 The comparison schematic diagram in . Among them, state A is the fiber coiling schematic diagram of the original oval fiber coiling structure; state B is the fiber coiling schematic diagram of the fiber coiling structure of this application.

[0057] Compared with circular, elliptical or waist-shaped fiber coiling structures, the first part and the second part are arranged at intervals in the direction of the vertical side, which can lengthen the length of the optical fiber coiled in each circle, so that the optical fiber coiled between the first part and the second part is approximately a straight line and will not be bent, thereby reducing the area or length ratio of the optical fiber being bent; in addition, the first arc-shaped guiding edge 100 and the second arc-shaped guiding edge 101 are spaced apart in the direction of the horizontal side, which is equivalent to dividing a semi-circle into two halves with a straight line or arc in the middle, so that the radius of the optical fiber being bent and guided is larger than the bending radius of a semi-circle, thereby weakening the impact of bending on the optical index.

[0058] The above structure of the fiber coiling structure 1 is also relatively simple, saving costs.

[0059] Furthermore, referring to Figure 3 , the present application also further improves the arrangement positions of the fiber coiling structure 1, the heat shrink tube limiting member 2, and the flange fixing member 3, specifically as follows:

[0060] The heat shrink tube limiting member 2 and the flange fixing member 3 are also provided on the bottom wall of the bottom shell of the fiber optic panel;

[0061] In the horizontal side direction, on one side of the fiber coiling structure 1, the flange fixing members 3 parallel to the vertical side are arranged at intervals, and on the other side, a first optical fiber channel is formed between it and the vertical side, marked C; a second optical fiber channel is formed between the flange fixing member 3 and the fiber coiling structure 1, marked D;

[0062] In the vertical side direction, on one side of the fiber coiling structure 1, the heat shrink tube limiting members 2 parallel to the horizontal side are arranged at intervals, and on the other side, a third optical fiber channel is formed between it and the horizontal side, marked E; a fourth optical fiber channel is formed between the heat shrink tube limiting member 2 and the fiber coiling structure 1, marked F.

[0063] The above arrangement form can enable the bottom shell of the fiber optic panel to accommodate a longer optical fiber to meet the extended length after fusion splicing.

[0064] For the present application, it should also be understood that in the above, the fiber coiling structure 1 is on the left and the flange fixing member 3 is on the right; the reverse is also feasible, that is, the layout is vertically mirrored, specifically manifested as the fiber coiling structure 1 is on the right and the flange fixing member 3 is on the left.

[0065] Furthermore, the above has introduced the setting method of increasing the bending radius of the fiber coiling, but for further fixing the optical fiber, referring to Figure 3 , there are also the following settings:

[0066] In the second optical fiber channel, and on the flange fixing member 3, a first optical fiber blocking piece 4 is provided; in the second optical fiber channel, and on the third arc-shaped guiding edge 103, a second optical fiber blocking piece 5 is provided;

[0067] In the first optical fiber channel, and on the side wall of the bottom shell of the fiber optic panel, a third optical fiber blocking piece 6 is provided; in the fourth optical fiber channel, and on the heat shrink tube limiting member 2, a fourth optical fiber blocking piece 7 is provided. In the height direction of the bottom shell of the fiber optic panel, there is a gap between the first optical fiber blocking piece 4, the second optical fiber blocking piece 5, the third optical fiber blocking piece 6, and the fourth optical fiber blocking piece 7 and the bottom wall of the bottom shell of the fiber optic panel; the first optical fiber blocking piece 4, the second optical fiber blocking piece 5, and the third optical fiber blocking piece 6 are parallel to the horizontal side; the fourth optical fiber blocking piece 7 is parallel to the vertical side.

[0068] Furthermore, referring to Figure 3 and Figure 6, for better guiding and to avoid the situation where the space of the second optical fiber channel is too small to pass through, the following settings are made:

[0069] In the horizontal side direction, the second arc-shaped guiding edge 101 and the flange fixing member 3 are on the same side; on the side of the second arc-shaped guiding edge 101 facing the second part, there is a second straight guiding edge 102 parallel to the vertical side; on the side of the first arc-shaped guiding edge 100 facing the second part, there is a third straight guiding edge 105 parallel to the vertical side; the third straight guiding edge 105 and the second straight guiding edge 102 are convenient for straight guiding.

[0070] In the horizontal side direction, the second part is within the range between the second straight guiding edge 102 and the third straight guiding edge 105, so as to ensure that there is enough space for the second optical fiber channel to pass through the optical fiber to meet the fiber coiling of different types and specifications of optical fibers.

[0071] In the second aspect, to further solve the problem that the heat shrinkable tube after fiber fusion needs to be placed at a fixed position above the bottom shell, and the bending radius is affected when the optical fiber exits because the size of the outer shell is 86mm * 86mm, the advantage of this application is that two paths for fiber fusion and non-fiber fusion are designed, which can ensure that the bending radii after fiber fusion and non-fiber fusion meet the requirements at the same time; to ensure a large bending radius, the following settings are specifically made:

[0072] One end of the first straight guiding edge 104 facing the first part is provided with a fourth straight guiding edge 106 parallel to the horizontal side direction;

[0073] In the vertical side direction, between the first part and the second part, there is a fifth straight guiding edge 107 parallel to the fourth straight guiding edge 106; a fifth optical fiber channel, marked G, is formed between the fifth straight guiding edge 107 and the fourth straight guiding edge 106;

[0074] There is a fifth optical fiber blocking piece 8 on the fifth straight guiding edge 107; in the height direction of the optical fiber panel bottom shell, there is a gap between the fifth optical fiber blocking piece 8 and the bottom wall of the optical fiber panel bottom shell.

[0075] The above fifth optical fiber blocking piece 8 is parallel or non-parallel to the horizontal side, as long as it can play a role in limiting in the height direction of the optical fiber panel bottom shell; similarly, the first optical fiber blocking piece 4, the second optical fiber blocking piece 5, the third optical fiber blocking piece 6 and the fourth optical fiber blocking piece 7 are also the same and can be non-parallel to the corresponding sides.

[0076] The above first optical fiber blocking piece 4, second optical fiber blocking piece 5, third optical fiber blocking piece 6, fourth optical fiber blocking piece 7 and fifth optical fiber blocking piece 8 can be in the same plane or not in the same plane. This is because only a gap is required between these five optical fiber blocking pieces and the bottom wall of the optical fiber panel bottom shell, and the optical fiber can pass through this gap. Of course, in this application appendix Figures 3 - 10In the structure shown, the five optical fiber stoppers are located in the plane of the top surface of the bottom shell of the optical fiber panel. Such a setting can increase the gap to facilitate the passage of optical fibers.

[0077] Reference Figure 5 and Figure 6 for comparison, Figure 5 For the path without fiber fusion: Second optical fiber channel D --- Third optical fiber channel E --- First optical fiber channel C --- Fourth optical fiber channel F --- Flange fixing part 3. Figure 6 For the path of fiber fusion: Second optical fiber channel D --- Third optical fiber channel E --- First optical fiber channel C --- Fourth optical fiber channel F --- Fifth optical fiber channel G --- First optical fiber channel C --- Fourth optical fiber channel F --- Flange fixing part 3. The above settings of the fourth straight guiding edge 106 and the fifth straight guiding edge 107 enable the length after fiber fusion to be coiled again through the fifth optical fiber channel G, so as to adapt to fiber fusion and non-fiber fusion operations.

[0078] Thirdly, to solve the operation of the bottom shell of the optical fiber panel to be compatible with surface-mounted and installed operations, the following settings are provided:

[0079] Concealed wiring

[0080] A concealed wiring port 9 is provided on the bottom wall of the bottom shell of the optical fiber panel;

[0081] In the vertical side direction, the concealed wiring port 9 is located between the fifth straight guiding edge 107 and the second straight guiding edge 102;

[0082] In the horizontal side direction, the concealed wiring port 9 is far from the flange fixing part 3; One vertical side of the concealed wiring port 9 is on the same straight line as the second straight guiding edge 102, and one horizontal side of the concealed wiring port 9 is on the same straight line as the fifth straight guiding edge 107. For the concealed installation operation, reference can be made to Figure 5 and Figure 6 for the schematic diagrams showing the coiled wire state of the concealed installation.

[0083] Among them, to facilitate separation and avoid confusion between optical fiber channels, the following settings are provided:

[0084] A baffle 10 is connected between the fifth straight guiding edge 107 and the second straight guiding edge 102, and the trajectory of the baffle 10 is the same as the trajectory formed by connecting the other vertical side and the other horizontal side of the concealed wiring port 9. The baffle 10, the fifth straight guiding edge 107 and the second straight guiding edge 102 form a complete structure.

[0085] Surface-mounted wiring

[0086] A number of surface-mounted wiring ports 11 are provided on the outer periphery of the bottom shell of the optical fiber panel. The wiring ports of the surface-mounted wiring ports 11 can be set according to the actual situation.

[0087] Thus, through the above description, the pre-coiled fiber path is designed, and the cable is controlled to move within a certain fiber channel, so that multi-specification cables can be compatible for fiber coiling, and buckles are designed in the vertical side direction and the horizontal side direction for limit

[0088] Fourthly, the present application also provides an optical fiber panel, which includes

[0089] The bottom shell of the optical fiber panel

[0090] The face shell 12 of the optical fiber panel, which is encapsulated on the bottom shell of the optical fiber panel. Reference can be made to the schematic diagrams shown in Figure 1 and Figure 2 The schematic diagram

[0091] For the present application, in Figures 5 - 10 , where the optical fiber and the flange fixture 3 overlap, it shows that the optical fiber is under the flange fixture 3; in actual applications, the optical fiber can be under the flange fixture 3 or above the flange fixture 3, and it is set according to the actual situation

[0092] In summary, the present application solves the problems of ensuring a larger bending radius and reducing the greater impact on optical indexes. The coiled fiber structure is shared by the fused and unfused optical fibers, different specifications of optical cables can be shared, and the fiber coiling of surface-mounted and concealed optical fibers can be taken into account
