Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, specifically to a pigtail for an outdoor combined optical cable junction box. Background Technology

[0002] An optical fiber distribution box is a network device used in fiber optic communication, primarily for connecting and wiring optical cables. Made of high-quality materials, it is corrosion-resistant, wear-resistant, and high-temperature resistant, meeting the needs of various environments. The optical fiber distribution box has a reasonable structural design, is easy to use, and can quickly and efficiently complete the connection and wiring of optical cables. It is widely used in large-scale networks, telecommunications, and cable television. A modular optical fiber distribution box is composed of multiple distribution boxes combined using connecting equipment, and pigtails are used to connect the optical cables to the fiber optic transceivers (couplers, patch cords, etc. are also used in between).

[0003] After the staff has connected the optical cables, there will be excess pigtails. Because these excess pigtails are inconvenient to store, they are usually fixed inside the optical cable junction box with bolts or placed directly at the bottom of the junction box. This causes the pigtails to become tangled. As a result, when the staff needs to rework a part of the optical cable, they have to sort out the pigtails and find the corresponding pigtails before they can make the corrections. This greatly increases the workload of the staff and reduces their work efficiency. To solve this problem, we provide a pigtail for an outdoor modular optical cable junction box. Summary of the Invention

[0004] The purpose of this utility model is to provide a pigtail for an outdoor combined optical cable junction box, in order to solve the problem that when staff need to rework a part of the optical cable, they need to first fix the pigtail, which greatly increases the workload of the staff and reduces their work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pigtail for an outdoor combined optical cable junction box, comprising: a box body, wherein a storage mechanism and an auxiliary unit are respectively arranged inside the box body; the storage mechanism includes: a lead screw, one end of which is fixedly connected to the inside of the box body; a turntable is provided on the outer wall of the lead screw; a clamping plate is provided inside the turntable; a first spring is installed between the clamping plate and the turntable; a fixed circular plate, wherein two connecting rods are fixedly connected to the back of the fixed circular plate; one end of the two connecting rods is fixedly connected to the inside of the box body; a push plate is provided on the inner wall of the fixed circular plate; two sliding rods are fixedly connected to the back of the push plate; a third spring is installed between the sliding rods and the fixed circular plate; a fixing block is fixedly connected to one end of the sliding rod; and a spherical rod is provided inside the fixing block.

[0006] As a further embodiment of this utility model: the outer wall of the lead screw is threadedly connected to the turntable, the turntable has a movable groove inside, a slide rod is slidably connected inside the movable groove, a first spring is installed between the slide rod and the movable groove, and a clamping plate is fixedly connected to the bottom of the slide rod.

[0007] As a further embodiment of this utility model: one end of each of the two sliding rods extends through the outside of the fixed circular plate, and the push plate is slidably connected to the fixed circular plate through the sliding rods.

[0008] As a further embodiment of this utility model: a spherical rod is slidably connected inside the fixing block, and a fourth spring is installed between the spherical rod and the fixing block. A winding cylinder is fixedly connected to one side of the turntable, and multiple abutment grooves are opened on the outside of the winding cylinder. The spherical rod initially abuts against the bottom of one of the abutment grooves, and one end of the abutment groove is provided with a slope.

[0009] As a further embodiment of this utility model: a limiting screw is provided on the top of the fixing block, and a threaded groove matching the limiting screw is opened on the top of the fixing block. The limiting screw is threadedly connected to the fixing block through the threaded groove, and the limiting screw is located below the spherical rod. An auxiliary groove is opened on one side of the housing, and two stops are slidably connected inside the auxiliary groove. Insert rods are provided at both ends of the stops. A slot matching the insert rods is opened on one side of the housing, and the insert rods are slidably connected to the housing through the slots.

[0010] As a further embodiment of this utility model: the auxiliary unit includes two sets of fixed seats fixedly connected to the side wall of the fixed circular plate. The inner side of each set of fixed seats is rotatably connected to a clamping roller via a rotating shaft. One side of one set of fixed seats is fixedly connected to two sets of limiting rods. One end of the limiting rod passes through the interior of the other set of fixed seats and is slidably connected to the other set of fixed seats. Two second springs are installed between the two sets of fixed seats.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting up components such as sliding rods, the clamping plate holds the tail end of the pigtail. At this time, the operator rotates the turntable by hand, so that the turntable moves forward on the lead screw, and at the same time drives the winding drum to move, so that the excess part of the pigtail can be wound on the winding drum. By winding the excess pigtail in an orderly manner, the space occupied by the pigtail is reduced, making it easier to store or move the pigtail equipment in a limited working environment. This makes it easier for the operator to sort the cables and improves the operator's work efficiency.

[0013] 2. By setting up push plates and other components, when the turntable drives the winding drum to rotate and move on the lead screw, the spherical rod rotates inside the abutment groove. While the winding drum moves, the abutment groove pushes the spherical rod to move towards the fixed circular plate, thereby pushing the sliding rod to move inside the fixed circular plate through the fixed block, and pushing the push plate through the sliding rod, and then pushing the tail fiber forward through the push plate, so that each turn of the tail fiber can be tightly attached, reducing the gap between each turn of the tail fiber. By pushing the tail fiber tightly attached turn by turn, the gap between turns caused by natural slack or operation error during tail fiber winding is eliminated, significantly improving the space utilization rate of the winding drum, and allowing longer tail fibers to be accommodated in a limited volume;

[0014] 3. By setting up an auxiliary unit, when collecting the pigtail, the operator inserts the end of the pigtail between two clamping rollers and then clamps it. As the winding drum rotates to collect the pigtail, the two clamping rollers, under the action of a second spring, hold the pigtail, ensuring that the pigtail between the clamping rollers and the winding drum remains in a slightly tight state. In the initial stage of winding, the clamping rollers quickly fix the pigtail in a slightly tight state, preventing the winding start section from loosening due to the slack of the free end of the pigtail. During the winding process, the continuous slightly tight force can counteract the elastic recoil caused by the change in the bending radius of the pigtail, avoiding gaps or accumulation between layers after multi-layer winding, thereby greatly improving the equipment's efficiency in collecting pigtails and thus greatly improving the work efficiency of the operators.

[0023] Please see Figures 1-5This embodiment provides a pigtail for an outdoor combined optical cable junction box, comprising: a box body 1, wherein a storage mechanism and an auxiliary unit are respectively arranged inside the box body 1; the storage mechanism includes: a lead screw 4, one end of which is fixedly connected to the inside of the box body 1; a turntable 5 is provided on the outer wall of the lead screw 4; a clamping plate 12 is provided inside the turntable 5; and a first spring 11 is installed between the clamping plate 12 and the turntable 5; a fixed circular plate 6, wherein two connecting rods 24 are fixedly connected to the back of the fixed circular plate 6; and one end of the two connecting rods 24 is fixedly connected to the box body. Inside the fixed circular plate 6, a push plate 17 is provided on the inner wall. Two sliding rods 18 are fixedly connected to the back of the push plate 17. A third spring 19 is installed between the sliding rods 18 and the fixed circular plate 6. A fixed block 20 is fixedly connected to one end of the sliding rod 18. A ball rod 21 is provided inside the fixed block 20. The outer wall of the lead screw 4 is threadedly connected to the turntable 5. A moving groove 10 is opened inside the turntable 5. A sliding rod 9 is slidably connected inside the moving groove 10. A first spring 11 is installed between the sliding rod 9 and the moving groove 10. A clamping plate 12 is fixedly connected to the bottom. One end of each of the two sliding rods 18 extends through the outside of the fixed circular plate 6. The push plate 17 is slidably connected to the fixed circular plate 6 via the sliding rods 18. A ball-shaped rod 21 is slidably connected inside the fixed block 20, and a fourth spring 22 is installed between the ball-shaped rod 21 and the fixed block 20. A winding cylinder 7 is fixedly connected to one side of the turntable 5, and multiple abutment grooves 8 are provided on the outside of the winding cylinder 7. The ball-shaped rod 21 initially abuts against the bottom of one of the abutment grooves 8, and one end of the abutment groove 8 is provided with... The inclined surface and the top of the fixing block 20 are provided with a limiting screw 23. The top of the fixing block 20 is provided with a threaded groove that matches the limiting screw 23. The limiting screw 23 is threadedly connected to the fixing block 20 through the threaded groove. The limiting screw 23 is located below the ball rod 21. An auxiliary groove 3 is provided on one side of the box body 1. Two stops 2 are slidably connected inside the auxiliary groove 3. Insert rods 25 are provided at both ends of the stops 2. A slot matching the insert rods 25 is provided on one side of the box body 1. The insert rods 25 are slidably connected to the box body 1 through the slots.

[0024] When workers need to collect the pigtails, they simply tie the excess pigtail ends with cable ties. Then, the workers lift the slide bar 9 by hand, which simultaneously lifts the clamping plate 12. The workers then insert the pigtail ends between the clamping plate 12 and the winding drum 7, and then release the slide bar 9. The clamping plate 12 holds the pigtail ends in place. The workers then rotate the turntable 5 by hand, causing it to move forward on the lead screw 4, which in turn moves the winding drum 7. This allows the excess pigtail to be wound onto the winding drum 7, thus reducing the space occupied by the pigtails by winding them in an orderly manner. This makes it easier to store or move the pigtail equipment in a limited working environment, which in turn makes it easier for workers to manage the cables and improves their work efficiency.

[0025] When the turntable 5 drives the winding cylinder 7 to rotate and move on the lead screw 4, the ball rod 21 rotates inside the abutment groove 8. While the winding cylinder 7 moves, the abutment groove 8 pushes the ball rod 21 to move towards the fixed circular plate 6, thereby pushing the sliding rod 18 to move inside the fixed circular plate 6 through the fixed block 20, and pushing the push plate 17 through the sliding rod 18, and then pushing the tail fiber forward through the push plate 17, so that each turn of the tail fiber can be tightly attached, reducing the gap between each turn of the tail fiber. The push plate 17 tightly attaches the tail fiber turn by turn, eliminating the gap between turns caused by natural slack or operation error during tail fiber winding, significantly improving the space utilization of the winding cylinder 7, and allowing longer tail fibers to be accommodated in a limited volume;

[0026] When the end of the ball rod 21 contacts the inclined surface inside the abutment groove 8, the ball rod 21 is pushed upward by the inclined surface. When the ball rod 21 moves from the lowest point to the highest point of the inclined surface of the abutment groove 8, the limit on the sliding rod 18 is released. Under the action of the third spring 19, the sliding rod 18 drives the ball rod 21 to move to the next abutment groove 8. When the bottom of the ball rod 21 moves to the next abutment groove 8, the ball rod 21 is pushed into the interior of the abutment groove 8 under the action of the fourth spring 22. The ball rod 21 continues to limit the sliding rod 18, so that the push plate 17 can be pushed back and forth, reducing the requirements for operating skills and thus improving the practicality of the equipment.

[0027] The initial top of the limiting screw 23 is separated from the ball rod 21, and there is a distance between the limiting screw 23 and the ball rod 21, so it will not hinder the movement of the ball rod 21.

[0028] When workers need to modify the pigtail, they only need to remove the two stops 2, then rotate the turntable 5 to separate the turntable 5 from the lead screw 4. Then, workers only need to pull the pigtail wrapped at the very end of the winding drum 7 to separate it from the winding drum 7. At this time, the tail end of the pigtail is still held by the clamp 12, which allows the pigtail to be quickly separated from the winding drum 7. Then, workers lift the clamp 12, find the corresponding pigtail, pull it out, and modify it. When it is necessary to reinstall the winding drum 7, workers only need to turn the limit screw 23 to lift it up. At the same time, the ball rod 21 is lifted up. Then, the winding drum 7 is aligned with the end of the lead screw 4, and the turntable 5 is rotated in the opposite direction to install it back onto the lead screw 4. Then, the limit screw 23 is reset so that the ball rod 21 continues to abut in the abutment groove 8. The above operation only requires workers to pull up the tail end of the pigtail. There is no need to sort the wires. Workers can directly find the corresponding pigtail, which speeds up the search time and greatly improves the work efficiency of workers.

[0029] Please see Figure 3The auxiliary unit includes two sets of fixed seats 13 fixedly connected to the side wall of the fixed circular plate 6. Each set of fixed seats 13 has a clamping roller 14 rotatably connected to its inner side via a rotating shaft. One side of one set of fixed seats 13 is fixedly connected to two sets of limiting rods 15. One end of the limiting rod 15 passes through the interior of the other set of fixed seats 13 and is slidably connected to the other set of fixed seats 13. Two second springs 16 are installed between the two sets of fixed seats 13.

[0030] When collecting the pigtail, the operator inserts the end of the pigtail between two clamping rollers 14 and clamps it. As the winding drum 7 rotates to collect the pigtail, the two clamping rollers 14, under the action of the second spring 16, clamp the pigtail, keeping it in a slightly tight state between the clamping rollers 14 and the winding drum 7. In the initial stage of winding, the clamping rollers 14 quickly fix the pigtail in a slightly tight state, preventing the starting section of winding from becoming loose due to the loosening of the free end of the pigtail. During the winding process, the continuous slightly tight force can counteract the elastic shrinkage of the pigtail caused by the change in bending radius, avoiding gaps or accumulation between layers after multi-layer winding, thereby greatly improving the efficiency of the equipment in collecting pigtails and thus greatly improving the work efficiency of the operator.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
