DETAILED DESCRIPTION

[0030] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The embodiment of the utility model provides an optical cable splice box, such as Figures 1 to 9 As shown, it includes a box body 1 and a mounting frame 2 arranged in the box body 1, one side of the mounting frame 2 is a connector mounting side 3, and the other side of the mounting frame 2 is an optical path mounting side 4;

[0032] A first mounting plate 31 is fixed on the surface of the connector mounting side 3. A plurality of groups of limit buckles 5 for detachably mounting an external optical fiber splicing tray 29 are convexly provided on the end surface of the first mounting plate 31 away from the connector mounting side 3. Each group of limit buckles 5 is arranged along the height direction of the mounting frame 2. The limit buckles 5 are provided with a slot 6 for inserting the optical fiber splicing tray 29 along a preset direction. The slot 6 has a limit surface 7 matching the insertion end 30 of the optical fiber splicing tray 29, so that the optical fiber splicing tray 29 is tilted downward and clamped on the limit buckle 5.

[0033] A second mounting plate 41 is fixed to the surface of the optical path mounting side 4, and the second mounting plate 41 is arranged perpendicular to the optical path mounting side 4. Terminal seats 8 are evenly distributed on both sides of the second mounting plate 41. An optical splitter 9 is also arranged on the surface of the optical path mounting side 4, and the optical splitter 9 is located below the second mounting plate 41.

[0034] Specifically, in this embodiment, the first mounting plate 31 has multiple sets of limit buckles 5 for installing the fiber optic fusion tray 29. The fiber optic fusion tray 29 is inserted into the limit buckles 5 horizontally and tilted downward under the action of the limit surface 7, thereby utilizing the space on the connector installation side 3 to a greater extent.

[0035] The limiting surface 7 is the groove wall of the slot 6, and the groove wall is a horizontal surface.

[0036] The terminal seat 8 and the optical splitter 9 are installed on the same side, and the optical fiber fusion tray 29 is placed on the opposite side of the optical splitter 9, reducing the probability of the optical fiber being broken and damaged due to the need for external connection between the optical cable joint box and the optical cable terminal box.

[0037] In a preferred embodiment of the utility model, a fiber optic storage tray 10 is arranged below the first mounting plate 31, and the fiber optic storage tray 10 includes a storage area for the fiber optic coil, and a wire management ring 11 is arranged in the storage area. The wire management ring 11 has a slot 12 for the fiber optic to enter and lead out, and a first wire pressing piece 13 is arranged on the side wall of the wire management ring 11.

[0038] Specifically, in this embodiment, a protective cover 14 is buckled above the storage area to protect the optical fiber arranged in the storage area.

[0039] An isolation seat 15 is fixed at the lower edge of the storage area. The isolation seat 15 includes a plurality of isolation units separated from each other. Each group of optical fibers can be led out separately through the isolation seat 15, which is convenient for assembly personnel to organize the optical fibers and reduces the probability of mutual influence on optical signal transmission due to lack of isolation after the optical fibers are led out.

[0040] The first wire pressing piece 13 can not only protect the optical fiber, but also ensure that the optical fiber is always located in the wire management ring 11, thereby preventing the optical fiber from being worn out due to escaping from the surface of the wire management ring 11.

[0041] In a preferred embodiment of the present invention, a guide post 16 is disposed in the middle of the cable management ring 11 and is used to guide the optical fiber to coil around the inner wall of the cable management ring 11 .

[0042] Specifically, in this embodiment, the optical fiber is coiled around the guide pin 16 in the cable management ring 11 to prevent the optical fiber from being broken due to excessive bending.

[0043] In a preferred embodiment of the utility model, a group of limit buckles 5 includes two limit units arranged in parallel, and the insertion end 30 of an optical fiber splicing tray 29 is respectively plugged into the two limit units of the same group;

[0044] The limiting unit includes two clips 17 arranged opposite to each other and in parallel, one end of the clip 17 is fixed to the first mounting plate 31, and the other end of the clip 17 has a stop portion 18 protruding toward the other opposite clip 17. When the insertion end 30 of the optical fiber fusion tray 29 is inserted into the limiting unit, the side of the insertion end 30 of the optical fiber fusion tray 29 away from the first mounting plate 31 abuts against the stop portion 18.

[0045] Specifically, in this embodiment, the gap between the two clips 17 forms a slot 6 for inserting the optical fiber splicing tray 29, the limiting surface 7 is the end surface of the two clips 17 close to each other, and the insertion end 30 of the optical fiber splicing tray 29 is square. Since the inner wall of the slot 6 is horizontal, when the insertion end 30 is inserted into the slot 6, the side wall of the insertion end 30 abuts against the inner wall of the slot 6, and the stopper 18 on the two clips 17 is close to each other and is connected to the side of the insertion end 30 away from the limiting unit, so that when the optical fiber splicing tray 29 is not subjected to external force, the optical fiber splicing tray 29 can maintain an inclined state and is not easy to deflect.

[0046] The clip 17 and the stopper 18 are made of plastic in one piece. The stopper 18 has a certain deformation recovery ability. When the assembler needs to remove the optical fiber fusion splice tray 29, the optical fiber fusion splice tray 29 can be pulled out in the horizontal direction, which is convenient to operate.

[0047] In a preferred embodiment of the utility model, wiring paths 19 are provided on both sides of the first mounting plate 31 , the wiring paths 19 are respectively connected to the storage area and the fiber optic fusion plate 29 , and the side of the wiring path 19 away from the first mounting plate 31 has a second wire pressing piece 20 .

[0048] Specifically, in this embodiment, the side of the protective cover 14 facing the wiring channel 19 has a clearance opening 21 for introducing optical fibers, so that the optical fibers can be introduced into the cable management ring 11 in an orderly manner.

[0049] The second pressing piece 20 is used to prevent the optical fiber from being squeezed and damaged by escaping from the wiring channel 19 .

[0050] In a preferred embodiment of the utility model, the box body 1 includes a base 22 for the optical cable to enter and exit and a cover body 23 that is snapped onto the base 22. The mounting frame 2 is fixed to the base 22. A positioning block 24 is provided at one end of the cover body 23 facing the base 22. The base 22 is provided with a plurality of positioning holes 25 along the circumference of the side wall for the positioning block 24 to be snapped into position.

[0051] Specifically, in this embodiment, the cover body 23 and the base 22 are detachably connected, and the assembler does not need to use tools such as screwdrivers or wrenches. The cover body 23 and the base 22 can be fixed and removed by simply rotating the positioning block 24, which is simple and convenient to operate.

[0052] In a preferred embodiment of the present utility model, one end of the positioning block 24 is rotatably connected to the cover body 23, and the other end of the positioning block 24 is inserted into the positioning hole 25. A limiting groove 26 is provided on the hole wall of the positioning hole 25, and a limiting protrusion 27 is convexly provided at one end of the positioning block 24 inserted into the positioning hole 25 to be snapped into the limiting groove 26.

[0053] Specifically, in this embodiment, the positioning block 24 and the limiting protrusion 27 are integrally formed and are made of plastic, which has a certain deformation recovery ability. The positioning block 24 is L-shaped, and the turning portion of the positioning block 24 is provided with a toothed portion 28 to adapt to the deformation of the positioning block 24 itself when the limiting protrusion 27 is inserted into the limiting groove 26, thereby improving the anti-fatigue ability of the positioning block 24.

[0054] When the limiting protrusion 27 of the positioning block 24 is engaged in the limiting groove 26 , the connection between the cover body 23 and the base 22 is firm and not easy to be loosened.

[0055] In summary, the two sides of the mounting frame 2 of the optical cable splice box are the splice mounting side 3 and the optical path mounting side 4, respectively. The splice mounting side 3 is for the installation of the optical fiber splice tray 29, and the optical path mounting side 4 is for the installation of the optical splitter 9. The space on both sides of the mounting frame 2 is utilized to a greater extent, thereby improving the space utilization rate of the optical cable splice box, and each optical fiber splice tray 29 is stacked obliquely, which can ensure that there is enough space for the optical fiber to be coiled after splicing. When installing the optical cable on site, the assembler does not need to carry an optical cable terminal box in addition to the optical cable splice box, which brings convenience to the installation of the optical cable.
