[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 fiber distribution box, such as Figures 1 to 9 As shown, it comprises a housing base 1 and a housing cover 2 rotatably connected to the housing base 1. One side of the housing base 1 is provided with at least two openings for cables or optical fibers to enter and exit. One opening is detachably connected to an inlet module 4, and the other opening is detachably connected to an outlet module 5.

[0032] A panel 6 is installed in the housing base 1. The panel 6 has a buffer on one side facing the bottom of the housing base 1. The buffer abuts against the bottom of the housing base 1 and has a restoring force. A support is provided on the other side of the panel 6. When the housing cover 2 is buckled on the housing base 1, a deformation gap is left between the support and the housing cover 2 and the support has a restoring force.

[0033] The optical cable splitter box further comprises an optical fiber tray 7 , and a mounting frame 8 for mounting the optical fiber tray 7 is also provided on one side of the panel 6 having the support member.

[0034] Specifically, in this embodiment, the panel 6 is fixed to the housing base 1 by bolts.

[0035] When the optical fiber tray 7 is installed on the mounting frame 8, the panel 6, the mounting frame 8 and the optical fiber tray 7 are surrounded to form a partition 9, and the optical fiber tray 7 is provided with a wiring hole 10 to connect the partition 9. A branching seat 11 is also provided in the middle of the optical fiber tray 7, and the branching seat 11 is fixed to the upper layer of the optical fiber tray 7. The branching seat 11 is provided with six partitioning holes 12 for the optical cable bundle to pass through after the optical cable is split.

[0036] The optical cable enters the base 1 of the housing through the inlet module 4, and a fiber bundle is obtained after fiber splitting processing. The partition 9 can be used for winding and storage of the fiber bundle. The fiber bundle goes to the top of the fiber tray 7 through the wiring hole 10, and is wound along the fiber tray 7. After being split into strands through the branching seat 11, the optical fiber is then led out through the outlet module 5.

[0037] The outlet module 5 may provide an interface group with three rows and four columns, or an interface group with four rows and six columns.

[0038] In a preferred embodiment of the utility model, the panel 6 is fixed with a plurality of discontinuous partitions 13, each partition 13 is constructed to form an annular mounting frame 8, a limiting platform 14 is fixed to one side of the mounting frame 8, a limiting shaft 15 is provided on one side of the optical fiber tray 7, and the limiting shaft 15 is clamped in the limiting platform 14, and the end of the partition 13 away from the panel 6 has a horizontal supporting portion 16 for the optical fiber tray 7 to be placed.

[0039] Specifically, in the present embodiment, a card plate 17 is protruded from the side of one of the separators 13 away from the panel 6, and a third card slot 18 for inserting the card plate 17 is provided on the side wall of the optical fiber tray 7 to prevent the optical fiber tray 7 from shifting toward the opening direction and to provide a guiding function for the installation of the optical fiber tray 7; a card block 19 is also provided on the side of the other separator 13 away from the panel 6, and a yield block 20 with a triangular longitudinal section is provided on the side of the optical fiber tray 7 away from the panel 6. When the optical fiber tray 7 is installed, the lower edge of the yield block 20 pushes the yield block 19, so that the corresponding separator 13 is slightly deformed in the direction away from the optical fiber tray 7, and then the optical fiber tray 7 continues to be pressed down to move the yield block 20 to the bottom of the yield block 19. At this time, the corresponding separator 13 is restored, and the upper end surface of the yield block 20 is against the lower end surface of the yield block 19, so that the optical fiber tray 7 is limited to the yield block 19 in the vertical direction.

[0040] The limit platform 14 is in the shape of a hoop and has an annular groove 21. By pressing down the limit shaft 15, the limit shaft 15 can be clamped in the annular groove 21, and a limit ring 22 is set in the middle of the limit shaft 15. The limit platform 14 is provided with a clearance hole 23 for the limit ring 22. When the user needs to check the optical cable in the compartment 9, the limit shaft 15 can be used as the rotation center to rotate the fiber tray 7 so that the clearance block 20 is separated from the card block 19 and the card plate 17 is separated from the card slot, which is convenient for operation. By setting multi-level positioning, it is convenient for users to install the fiber tray 7, and the connection strength between the fiber tray 7 and the panel 6 is also improved.

[0041] The wiring hole 10 is provided on a side of the optical fiber tray 7 close to the limiting axis 15 to prevent the optical cable and the optical fiber from being pulled and broken when the user rotates the optical fiber tray 7 .

[0042] In a preferred embodiment of the present invention, the buffer member includes a plurality of arcuate pieces 24 distributed around the panel 6, one end of the arcuate piece 24 is bent toward the bottom of the shell base 1 and abuts against the bottom of the shell base 1, and the other end of the arcuate piece 24 is integrally arranged with the panel 6.

[0043] Specifically, in this embodiment, the arc piece 24 is formed by die-casting the panel 6, and the bottom of the arc piece 24 is bent into a bow shape and abuts against the bottom of the shell base 1. When there is vibration between the panel 6 and the shell base 1, the arc piece 24 deforms to unload the force, thereby eliminating the vibration of the panel 6 or reducing the vibration amplitude of the panel 6, thereby improving the seismic resistance of the optical cable fiber distribution box.

[0044] In a preferred embodiment of the utility model, the support member includes a plurality of support sheets 25 circumferentially distributed on the outer edge of the panel 6, the support sheet 25 is vertically arranged and one end of the support sheet 25 away from the panel 6 is bent to form a resistance portion 26, and when the outer shell cover 2 is buckled on the outer shell base 1, a deformation gap is left between the resistance portion 26 and the outer shell cover 2.

[0045] Specifically, in this embodiment, when the outer shell cover 2 is impacted by external force, part of the external force is transmitted to the support plate 25, and the support plate 25 absorbs this part of the external force by deforming under the force, so as to reduce the deformation probability of the outer shell cover 2, improve the structural strength of the optical cable fiber distribution box, and thus play a role in protecting the optical fiber in the optical cable fiber distribution box.

[0046] In a preferred embodiment of the utility model, a first column 27 is provided on a side of the shell base 1 away from the opening, and a second column 28 is provided on a side of the shell cover 2. The optical cable fiber distribution box also includes a pin 29, which passes through the first column 27 and the second column 28 in sequence, and the second column 28 is rotatably connected to the pin 29.

[0047] Specifically, in this embodiment, when the outer shell cover 2 is buckled with the outer shell base 1, the latch 29 is the rotation center of the outer shell cover 2. Among them, the first columns 27 are fixed to the two ends of the outer shell base 1 in pairs, and the second column 28 is located between the two first columns 27 in pairs. One end of the latch 29 has a limit cap 30, and the other end of the latch 29 has a limit foot 31 arranged oppositely, and the end faces of the limit foot 31 away from each other are provided with a stop block 32, and the first column 27 and the second column 28 are sandwiched between the limit cap 30 and the limit foot 31.

[0048] In a preferred embodiment of the present invention, the latch 29 is axially limited to the first column 27 and the second column 28, and clamping columns 33 fixed to the shell base 1 are respectively provided on both sides of the latch 29 along the radial direction, and the latch 29 is provided with a clamping groove 34 for the clamping column 33 to be engaged.

[0049] Specifically, in this embodiment, when the clamping column 33 is clamped in the clamping groove 34, the latch 29 is circumferentially limited, so that the outer shell cover 2 can rotate around a fixed axis to avoid the situation where the latch 29 is driven to rotate when the outer shell cover 2 rotates.

[0050] In a preferred embodiment of the present invention, elastic snaps 35 are respectively provided on both sides of the opening, the inlet module 4 is provided with a first slot 36 for the corresponding elastic snaps 35 to engage, and the outlet module 5 is provided with a second slot 37 for the corresponding elastic snaps 35 to engage.

[0051] Specifically, in this embodiment, the elastic clip 35 is formed by die-casting the shell base 1, and the elastic clip 35 is arranged on the two side groove walls opposite to the first slot 36 and the two side groove walls opposite to the second slot 37. There are notches 38 on both sides of the elastic clip 35, so that the elastic clip 35 can be deflected in the direction away from each other, and positioning blocks 39 are convexly provided on the end surfaces of the two elastic clips 35 that are close to each other. Then, first positioning grooves 40 are opened on both sides of the inlet module 4 to be snapped into the corresponding positioning blocks 39, and second positioning grooves 41 are opened on both sides of the outlet module 5 to be snapped into the corresponding positioning blocks 39.

[0052] In a preferred embodiment of the utility model, the shell base 1 has a cavity for installing the panel 6, and a stepped plug 42 with an adjustable inner diameter is provided on the side of the inlet module facing the panel 6, one end of the stepped plug 42 is connected to the outside of the optical cable fiber distribution box, and the other end of the stepped plug 42 is connected to the cavity.

[0053] Specifically, in this embodiment, the inlet module is provided with a mounting hole for the stepped plug 42 to be installed. The stepped plug 42 includes a base 44 for being snapped into the mounting hole. One side of the base 44 is provided with connecting rings 45 with a diameter of 12 cm, a diameter of 10 cm, and a diameter of 7 cm in sequence. Each connecting ring 45 is eccentrically arranged and located at the lower edge of the previous connecting ring 45. In actual use, the user can cut the stepped plug 42 according to the diameter of the optical cable, and use the connecting ring 45 adapted to the diameter of the optical cable for the optical cable to pass through.

[0054] In a preferred embodiment of the utility model, the optical cable fiber distribution box also includes a locking structure, which includes a locking plate 46 rotatably connected to the shell base 1 and a strap 47 fixed to the shell cover 2 facing the opening side. When the shell cover 2 is buckled on the shell base 1, one end of the locking plate 46 rotates to the side of the strap 47 away from the shell base 1 and abuts against the strap 47.

[0055] Specifically, in this embodiment, the lock structure is equipped with a key 48, a lock column 49 is rotatably provided on the housing base 1, one end of which is for the key 48 to be inserted, and the lock plate 46 is fixed to the other end of the lock column 49. One end of the key 48 has an unlocking block 50, and the lock column 49 is provided with an unlocking hole 51 for the unlocking block 50 to be engaged. When the key 48 is inserted into the lock column 49 and the unlocking block 50 is engaged in the unlocking hole 51, the lock plate 46 can be driven to rotate along the axis of the lock column 49 as the rotation center by rotating the key 48. When the lock plate 46 rotates to the horizontal, the lock plate 46 is located on one side of the strap 47, and the two are not locked; when the lock plate 46 rotates to the vertical, the lock plate 46 is located above the strap 47, and the two are locked to prevent the housing cover 2 from being accidentally opened.

[0056] In addition, inserts 52 are provided on both sides of the outer shell cover 2. One end of the inserts 52 is fixed to the side of the outer shell cover 2 close to the outlet. The other end of the inserts 52 is integrally formed with a boss 53. The outer shell base 1 is provided with a groove 54 for inserting the inserts 52. The groove wall of the groove 54 is provided with a through hole 55 for the boss 53 to engage. When the outer shell cover 2 is buckled on the outer shell base 1, the inserts 52 are inserted into the groove 54, and the boss 53 is engaged in the through hole 55. Among them, the groove 54 also leaves a space for the inserts 52 to bend toward the outlet. When the user needs to open the outer shell cover 2, first unlock the lock plate 46 and the strap 47, then squeeze the inserts 52 to disengage the boss 53 from the through hole 55, and then flip the outer shell cover 2. The operation is convenient. By providing the inserts 52, the connection strength between the outer shell cover 2 and the outer shell base 1 is improved.

[0057] In a preferred embodiment of the present invention, a honeycomb-shaped heat dissipation groove 56 is formed on one side of the housing cover 2 facing the housing base 1 .

[0058] Specifically, in this embodiment, the heat dissipation efficiency of the optical cable fiber distribution box is improved by providing a honeycomb-shaped heat dissipation groove 56 .

[0059] A support platform 57 is also provided on one side of the panel 6 near the outlet. The upper surface of the support platform 57 is arc-shaped. When the optical cable enters the cavity through the outlet, the optical cable can be placed on the support platform 57, so that the optical cable distribution inside the optical cable fiber distribution box is more orderly.

[0060] In summary, when the optical fiber splitter box is impacted by external force, the support member between the panel 6 and the outer shell cover 2 resists and absorbs part of the impact force by deformation, reducing the deformation probability of the outer shell cover 2, thereby protecting the optical fiber and related parts; when the optical fiber splitter box vibrates under the action of external force, the vibration of the outer shell base 1 is buffered by the deformation of the buffer member, so that the vibration amplitude directly acting on the optical fiber tray 7 is reduced, thereby improving the shock-proof and impact-resistant ability of the optical fiber splitter box, making the structural strength of the optical fiber splitter box more reliable. Since the support member and the buffer member both have restoring force, when the external force no longer acts on the optical fiber splitter box, the support member and the buffer member can return to their original shape, thereby improving the durability of the optical fiber splitter box.
