Description

Technical Field

[0001] This utility model relates to the field of fiber splitter box technology, and in particular to an optical fiber splitter box. Background Technology

[0002] Fiber optic distribution boxes are interface devices used to connect trunk optical cables and distribution optical cables outdoors, in corridors, or indoors. They are suitable for various scenarios such as indoor and outdoor use, wall mounting, pole mounting, and new and old buildings. They are used for the wiring connection of optical cables and optical communication equipment. Through the adapter in the distribution box, optical signals are led out with fiber optic patch cords to realize the optical wiring function.

[0003] After the fiber optic box is installed, the optical cable connected to the inside of the fiber optic box may be accidentally pulled hard during subsequent maintenance and fiber optic installation, causing the connection between the optical cable and the inside of the fiber optic box to break, affecting the normal use of the internal circuitry of the fiber optic box. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the optical cable connected to the inside of the optical fiber box may be accidentally pulled too hard during subsequent maintenance and optical fiber installation, causing the connection between the optical cable and the inside of the optical fiber box to break, thus affecting the normal use of the circuit inside the optical fiber box. Therefore, an optical fiber splitter box is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an 18-core 5-way fiber optic distribution box, comprising a box body, a box cover rotatably disposed on one side of the box body, a cable plate slidably inserted on one side of the box cover, a splicing tray disposed inside the box body, two cable passage holes opened on one side of the box body, an auxiliary device installed on the outer surface of the box body near the cable passage holes by means of a convenient device, the auxiliary device fixing the cable to the box body, the auxiliary device comprising two slotted rods, the two slotted rods respectively fixed to one side of the box body by means of a convenient device, a U-shaped rod slidably connected to the inner wall of the slotted rod, a rectangular block fixedly connected to one side of the U-shaped rod, two through holes opened on the outer surface of the rectangular block, a screw rotatably connected to one side of the rectangular block, a slotted block threadedly connected to the outer surface of the screw, two sliding rods fixedly connected to one side of the slotted block, the outer surface of the sliding rods sliding on the inner wall of the rectangular block, a pressure block fixedly connected to one end of the sliding rod, two springs disposed on one side of the U-shaped rod, the two ends of the two springs respectively fixedly connected to one side of the U-shaped rod and one end of the slotted rod.

[0006] The aforementioned components achieve the following effect: By setting pressure blocks, when using the fiber distribution box to splice optical cables through the cable holes to the optical fibers in the splice tray inside the box, the auxiliary device can be conveniently installed on one side of the box. Then, the optical cable is passed through the two through holes on the outer surface of the rectangular block. Rotating the screw controls the groove block to move on the outer surface of the screw, causing the sliding rod to slide on the inner wall of the rectangular block. This causes the pressure blocks at one end of the two sliding rods to press against the outer surfaces of the two optical cables, fixing the position of the optical cable inside the through holes on the outer surface of the rectangular block. After the fiber distribution box is installed, when the optical cable is pulled, the pressure of the pressure blocks causes the optical cable to move, which in turn moves the U-shaped rod away from the groove rod and compresses the spring on the outer surface of the U-shaped rod. The spring's thrust buffers the movement of the U-shaped rod, and the groove rod limits the range of movement of the U-shaped rod, preventing the optical cable from being pulled outward a long distance. This minimizes the risk of the optical cable being subjected to excessive pulling force, which could cause the connection with the wiring in the splice tray to break, affecting the normal operation of the fiber distribution box.

[0007] Preferably, a gasket is fixedly connected to one side of the pressure block, and the gasket is made of rubber.

[0008] The effect achieved by the above components is that when the side of the pressure block with the rubber pressure plate is pressed against the outer surface of the cable, the cable is more stably fixed inside the through hole and is less likely to slip.

[0009] Preferably, one end of the screw is fixedly connected to an operating block, and the outer surface of the operating block is provided with several protrusions.

[0010] The effect achieved by the above components is that the protrusions on the outer surface of the operating block make it easier to rotate the operating block to control the screw rotation and prevent the hand from slipping.

[0011] Preferably, two round rods are fixedly connected to one side of the U-shaped rod, and the outer surfaces of the two round rods slide on one end of the inner wall of the groove rod.

[0012] The effect achieved by the above components is that when the optical cable is stretched and the U-shaped rod moves, the two round rods will slide at one end of the inner wall of the groove rod. The round rods can further limit the angle between the U-shaped rod and the groove rod, and avoid the U-shaped rod from tilting as much as possible.

[0013] Preferably, the diameter of the round rod is slightly smaller than the inner diameter of the spring, and the round rod is located inside the spring.

[0014] The effect achieved by the above components is that when the U-shaped rod moves and causes the spring to deform, the spring will move on the outside of the round rod. The round rod can reinforce the internal shape of the spring and minimize the lateral twisting of the spring, which would affect its normal use.

[0015] Preferably, auxiliary rings are fixedly connected to the two ends of the inner wall of the through hole, and the outer surface edge of the auxiliary rings is arc-shaped.

[0016] The effect achieved by the above components is that by setting the auxiliary ring, when the optical cable is located inside the through hole, it is less likely to cause wear and damage to the outer surface of the optical cable when it comes into contact with the outer edge of the auxiliary ring.

[0017] Preferably, the convenient device includes two protrusions, one side of each of the two protrusions is fixedly connected to one side of each of the two grooved rods, bolts are slidably inserted into the inner wall of the protrusions, and two threaded holes are opened on one side of the box body, with the outer surface of the bolts threadedly connected to the inner wall of the threaded holes.

[0018] The effect achieved by the above components is as follows: When installing the auxiliary device, the protrusions on one side of the two grooved rods are attached to the outer surface of the box. Then, the bolts are inserted through the protrusions into the threaded holes on the outer surface of the box. By rotating the bolts to make the bolts threaded into the inner wall of the threaded holes, the protrusions and auxiliary devices can be fixed to one side of the box. By rotating the bolts to make the bolts disengage from the inside of the threaded holes, the auxiliary devices can be disassembled, thus improving the convenience of using the auxiliary devices.

[0019] Preferably, an elastic rope is fixedly connected to one side of the protrusion, and the end of the elastic rope away from the protrusion is fixedly connected to one end of the bolt.

[0020] The effect achieved by the above components is that by setting an elastic rope, the protrusion can always be fixed to one side of the protrusion, making it easy to pick up and use the bolt and preventing the bolt from falling off and being lost.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting an auxiliary device, the optical cable is fixed inside the rectangular block. When the optical cable is pulled, it will drive the U-shaped rod to move away from the groove rod and compress the spring on the outer surface of the U-shaped rod. The spring's thrust buffers the movement of the U-shaped rod, and the groove rod limits the range of movement of the U-shaped rod, preventing the optical cable from being pulled outward a long distance. This minimizes the risk of the optical cable being subjected to excessive pulling force, which could cause the connection with the wiring in the splice tray to break and affect the normal operation of the fiber distribution box.

[0029] Example 1, as Figure 1-5As shown, an optical fiber splitter box includes a box body 1. A cover 4 is rotatably mounted on one side of the box body 1. A cable plate 5 is slidably inserted into one side of the cover 4. A splice tray 6 is provided inside the box body 1. Two cable passage holes 7 are opened on one side of the box body 1. An auxiliary device 2 is installed on the outer surface of the box body 1 near the cable passage holes 7 by means of a convenient device 3. The auxiliary device 2 includes two slotted rods 21. The two slotted rods 21 are respectively fixed to one side of the box body 1 by means of the convenient device 3. A U-shaped rod 22 is slidably connected to the inner wall of the slotted rods 21. One side of the U-shaped rod 22 is fixed. A rectangular block 23 is connected, with two through holes on its outer surface. A screw 24 is rotatably connected to one side of the rectangular block 23, and a groove block 25 is threaded onto the outer surface of the screw 24. Two sliding rods 26 are fixedly connected to one side of the groove block 25, and their outer surfaces slide against the inner wall of the rectangular block 23. A pressure block 27 is fixedly connected to one end of each sliding rod 26. Two springs 29 are provided on one side of a U-shaped rod 22, and their two ends are fixedly connected to one side of the U-shaped rod 22 and one end of the groove block 21, respectively. By setting the pressure block 27... When splicing optical cables through the cable guide hole 7 to the optical fiber in the splice tray 6 inside the box 1 using the fiber distribution box 27, the auxiliary device 2 can be installed on one side of the box 1 with the help of the convenient device 3. Then, the optical cable is passed through the two through holes on the outer surface of the rectangular block 23. Rotating the screw 24 controls the groove block 25 to move on the outer surface of the screw 24, which drives the sliding rod 26 to slide on the inner wall of the rectangular block 23. This causes the pressure blocks 27 at one end of the two sliding rods 26 to press against the outer surfaces of the two optical cables respectively, thus adjusting the position of the optical cable inside the through holes on the outer surface of the rectangular block 23. After the fiber distribution box is installed and fixed, when the optical cable is pulled, the pressure block 27 presses the optical cable, causing the optical cable to move. This causes the U-shaped rod 22 to move away from the groove rod 21 and compress the spring 29 on the outer surface of the U-shaped rod 22. The thrust of the spring 29 buffers the movement of the U-shaped rod 22, and the groove rod 21 limits the range of movement of the U-shaped rod 22, preventing the optical cable from being pulled outward a long distance. This minimizes the risk of the optical cable being subjected to large tensile forces that could cause the connection with the wiring in the splice tray 6 to break, affecting the normal operation of the fiber distribution box.

[0030] Reference Figure 2-5 As shown in this embodiment: a pad 28 is fixedly connected to one side of the pressure block 27. The pad 28 is made of rubber. When the side of the pressure block 27 with the rubber pad is pressed against the outer surface of the cable, the cable is more stably fixed in the position inside the through hole and is not easy to slip. An operating block 210 is fixedly connected to one end of the screw 24. Several protrusions are provided on the outer surface of the operating block 210. Holding the protrusions on the outer surface of the operating block 210 makes it easier to rotate the operating block 210 to control the rotation of the screw 24 and prevents the hand from slipping.

[0031] Reference Figure 2-5As shown in this embodiment: Two round rods 211 are fixedly connected to one side of the U-shaped rod 22. The outer surfaces of the two round rods 211 slide on one end of the inner wall of the groove rod 21. When the optical cable is pulled and the U-shaped rod 22 moves, the two round rods 211 will slide on one end of the inner wall of the groove rod 21. The round rods 211 can further limit the angle between the U-shaped rod 22 and the groove rod 21, and avoid the angle of the U-shaped rod 22 from deflecting as much as possible. The diameter of the round rods 211 is slightly smaller than the inner diameter of the spring 29. The round rods 211 are located inside the spring 29. When the U-shaped rod 22 moves and causes the spring 29 to deform, the spring 29 will move outside the round rod 211. The round rod 211 can reinforce the internal shape of the spring 29 and avoid the spring 29 from twisting laterally, which would affect normal use. Auxiliary rings 212 are fixedly connected to the two ends of the inner wall of the through hole. The outer surface edge of the auxiliary ring 212 is arc-shaped. By setting the auxiliary ring 212, when the optical cable is inside the through hole, it is less likely to come into contact with the outer surface edge of the auxiliary ring 212 and cause wear and damage to the outer surface of the optical cable.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown in this embodiment: the convenient device 3 includes two protrusions 32, one side of each of the two protrusions 32 is fixedly connected to one side of each of the two grooved rods 21, and bolts 33 are slidably inserted into the inner wall of the protrusions 32. Two threaded holes 31 are opened on one side of the box body 1, and the outer surface of the bolts 33 is threadedly connected to the inner wall of the threaded holes 31. When installing the auxiliary device 2, the protrusions 32 on one side of the two grooved rods 21 are attached to the outer surface of the box body 1, and then the bolts 33 are inserted through the protrusions 32 into the threaded holes 31 on the outer surface of the box body 1. The bolts 33 are rotated to make the bolts 33... The protrusion 32 and the auxiliary device 2 can be fixed to one side of the box body 1 by connecting the threaded connection to the inner wall of the threaded hole 31. The auxiliary device 2 can be disassembled by rotating the bolt 33 to disengage it from the inside of the threaded hole 31, which improves the convenience of using the auxiliary device 2. An elastic rope 34 is fixedly connected to one side of the protrusion 32. The end of the elastic rope 34 away from the protrusion 32 is fixedly connected to one end of the bolt 33. By setting the elastic rope 34, the protrusion 32 can always be fixed to one side of the protrusion 32, which makes it easy to pick up the bolt 33 and prevents the bolt 33 from falling and being lost.

[0033] Working principle: When using the fiber splitter box, attach the protrusions 32 on one side of the two slotted rods 21 to the outer surface of the box body 1. Then, use bolts 33 to pass through the protrusions 32 and insert them into the threaded holes 31 on the outer surface of the box body 1. Rotate the bolts 33 to make the bolts 33 threaded into the inner wall of the threaded holes 31, thus fixing the protrusions 32 and auxiliary devices 2 to one side of the box body 1. Then, pass the optical cable through the two through holes on the outer surface of the rectangular block 23 and the cable passage hole 7 on the outer surface of the box body 1 into the box body 1. Splice one end of the optical cable with the optical fiber inside the splice tray 6, and fix the flange of the optical fiber at the line plate 5. Connect the user-end optical fiber connector to the optical fiber flange at the line plate 5 to achieve fiber splitting for that optical fiber. Then, close the box body 1 with the cover 4 and rotate the screw 24 to control the fiber splitting. The groove block 25 moves on the outer surface of the screw 24, causing the sliding rod 26 to slide on the inner wall of the rectangular block 23. This causes the pressure blocks 27 at one end of the two sliding rods 26 to press against the outer surfaces of the two optical cables, fixing the position of the optical cables inside the through holes on the outer surface of the rectangular block 23. When the fiber distribution box is in operation, if the optical cable is accidentally pulled, the pressure of the pressure block 27 will cause the optical cable to move, which will drive the U-shaped rod 22 to move away from the groove rod 21 and compress the spring 29 on the outer surface of the U-shaped rod 22. The thrust of the spring 29 buffers the movement of the U-shaped rod 22, and the groove rod 21 limits the range of movement of the U-shaped rod 22, preventing the optical cable from being pulled outward a long distance and minimizing the risk of the optical cable being subjected to large tensile forces that could cause the connection with the circuit in the splice tray 6 to break.
