Description

Technical Field

[0001] The present invention relates to the technical field of 10G optical fiber composite cables for communication, and in particular to a 10G optical fiber composite cable for communication and a manufacturing method thereof. Background Art

[0002] Optical-electric composite cable is suitable for use as a transmission line in broadband access network systems. It is a new type of access method that integrates optical fiber and power transmission copper wire to solve the problems of broadband access, equipment power consumption, and signal transmission. It includes an internal core wire, a protective layer outside the core wire, a filling layer to fill the gaps between the core wires, an armor layer outside the protective layer, and an external sheath layer. During the production process, various parts will be adjusted to cope with different usage environments to ensure that the cable maintains a good transmission state in a complex natural environment.

[0003] However, during actual use, the inventors found that since the armor layer is fixed to the inner layer of the composite cable by rotational wrapping during the cable production process, and since the friction between the armor layer and the inner layer is small, the two are easily misaligned and separated during operation and use, thereby changing the position of the armor layer inside the cable, causing the shape of the cable to change and even compressing the internal optical fiber to affect signal transmission. At the same time, when the cable is damaged due to the complex external environment, affecting signal transmission, the staff cannot quickly find the damaged location of the cable in a short time, which leads to technical problems such as low work efficiency.

[0015] Beneficial effects of the present invention: (1) In the present invention, a first protective mechanism is provided, wherein a lifting component and a shaping component are used to fold the armor into a depression corresponding to the groove on the inner layer of the composite cable, and then the first winding component is used to clamp the two together, thereby ensuring that the armor layer and the inner layer of the composite cable are tightly connected, and sliding and dislocation are not likely to occur, thereby improving the overall strength and deformation resistance of the cable; (2) In the present invention, by providing a groove formed on the inner layer of the composite cable, firstly, the connection between the armor layer and the inner layer of the composite cable is ensured; secondly, the shape setting of the narrow top and wide bottom ensures that the armor will not shake in all directions after entering the groove; thirdly, the arc-shaped setting of the bottom allows the downward pressure of the internal water-absorbing particles to expand and diffuse to the surroundings, thereby reducing the vertical downward pressure and ensuring that the optical fiber signal is not affected. At the same time, the bottom of the arc is located in the same axial direction as the cable core part bracket, further reducing the pressure effect; (3) In the present invention, a second protective mechanism is provided, and the water-absorbing particles are fixed in the groove on the inner layer of the composite cable by the water-absorbing cloth using the second winding component and the releasing component. Then, the cable as a whole is monitored by the cooperation between the water-absorbing cloth and the water-absorbing particles. When the outer layer of the composite cable is damaged, the water enters and is conducted to the position of the water-absorbing particles by the water-absorbing cloth. Then, the water-absorbing particles expand and cause the outer layer of the composite cable to bulge. Thus, the water is controlled and will not erode the inside. At the same time, it is convenient for the staff to find it, thereby ensuring the maintenance efficiency. (4) In the present invention, by providing a cooling component and a testing component in the detection mechanism, the cable can be quickly cooled after processing. At the same time, the outer layer of the composite cable is tested by bending and twisting in all directions to ensure that the produced cable will not have undetected gaps or cracks.

[0033] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0034] Embodiment 1 like Figure 1 to Figure 2 and Figure 3 As shown, a 10G optical-electrical composite cable for communication includes: The first coating station I, the second coating station II and the performance testing station III are arranged in sequence along the cable transmission direction; The first coating station I is provided with a first protection mechanism 1 for installing the armor 500 on the inner layer 200 of the composite cable, the second coating station II is provided with a second protection mechanism 2 for installing and fixing the water-absorbing particles 300, and the performance testing station III is provided with a detection mechanism 3 for cooling the cable and detecting the integrity of the outer layer 400 of the composite cable; The first protective mechanism 1 includes a first winding component 11 arranged on the frame 100 and used to output the armor 500, a lifting component 12 arranged on the frame 100 and used to lift the armor 500, and a shaping component 13 arranged on the lifting component 12 and used to shape the armor 500 so as to adapt to the groove 600 on the inner layer 200 of the composite cable.

[0035] In this embodiment, by setting a groove 600 formed on the inner layer 200 of the composite cable, firstly, the connection between the armor 500 layer and the inner layer 200 of the composite cable is ensured; secondly, its shape setting of being narrow at the top and wide at the bottom ensures that the armor 500 will not shake in all directions after entering the groove 600; thirdly, its bottom arc setting allows the downward pressure of the internal water-absorbing particles 300 after expansion to diffuse to the surroundings, reducing the vertical downward pressure, thereby ensuring that the optical fiber signal is not affected; at the same time, the bottom of the arc is located in the same axial direction as the cable core part bracket 800, further reducing the pressure effect; wherein the first protective mechanism 1, wherein the armor 500 is folded into a depression corresponding to the groove 600 on the inner layer 200 of the composite cable by using the lifting component 12 and the shaping component 13, and then the two are clamped together in cooperation with the first winding component 11, thereby ensuring that the connection between the armor 500 layer and the inner layer 200 of the composite cable is tight, and sliding and dislocation are not easy to occur, thereby improving the overall strength and deformation resistance of the cable.

[0036] In detail, the cable core and the bracket 800 are first combined and the surrounding filling is completed, and then the inner layer 200 of the composite cable and the groove 600 are extruded by an extruder. Then, after preliminary cooling and shaping, it moves toward the first coating station I. Then, under the action of the first protective mechanism 1, the armor 500 layer is installed and engaged with the groove 600. Then, the water-absorbing particles 300 and the water-absorbing cloth 700 are installed at the position of the second protective mechanism 2. Finally, after the outer layer 400 of the composite cable is extruded, cooling and crack detection are carried out at the position of the detection mechanism 3.

[0037] Further, if Figures 3 to 5As shown, the first winding assembly 11 includes a mounting frame 112 connected to the frame 100 and provided with a guide rail 111, a driving rod 113 connected to the guide rail 111, a first rotating shaft 114 connected to the driving rod 113 and used to output the armor 500, a compensation gear 115 connected to the first rotating shaft 114, an arc-shaped rack 116 connected to the mounting frame 112 and meshing with the compensation gear 115, a driving ring 117 provided on the mounting frame 112 and used to drive the driving rod 113 to move, and a first motor 118 provided on the mounting frame 112 and used to drive the driving ring 117 to rotate.

[0038] In this embodiment, firstly, by providing a compensating gear 115 and an arc-shaped rack 116, the armor 500 can extend an excess portion before shaping each time to bend into a shape suitable for the groove 600, thereby ensuring that the armor 500 will not be excessively stretched and deformed, thereby affecting its own strength. At the same time, an inwardly moving arc portion is provided on the guide rail 111, which is used to slow down the stretching of the armor 500 and cooperate with the shaping component 13 to squeeze the deformed portion of the armor 500 into the inside of the groove 600.

[0039] In detail, during the cable transportation process, the first motor 118 drives the driving ring 117 to rotate, and the driving ring 117 drives the driving rod 113 to rotate inside the guide track 111, thereby driving the first rotating shaft 114 and the armor 500 to rotate and wrap around the cable.

[0040] It should be noted that a damper is disposed between the first rotating shaft 114 and the driving rod 113 .

[0041] Further, if Figures 3 to 6 As shown, the lifting assembly 12 includes a driving cylinder 122 connected to the frame 100 and having an output end connected to a mounting column 121, a first gear 123 connected to the frame 100, a first rack 124 and a second rack 125 connected to the frame 100 and the mounting column 121 respectively and meshing with the first gear 123 for transmission, a connecting rod 128 connected to the first rack 124 through a first telescopic member 126 and having one end connected to a shaping seat 127, a trapezoidal block 129 connected to the frame 100 and used to drive the connecting rod 128 to move upward, and a blocking rod 1210 arranged on the frame 100; The shaping component 13 includes a mounting rod 131 connected to the mounting column 121, a shaping frame 133 connected to one end of the mounting rod 131 through a second telescopic member 132, an arc groove 134 opened on the shaping frame 133, a shaping clip 135 connected in the arc groove 134, a driving block 136 connected to the mounting rod 131 and used to drive the shaping clip 135 to work, and a positioning block 137 connected to the shaping frame 133 and located in the groove 600.

[0042] In this embodiment, the height is adjusted by setting a trapezoidal block 129 in cooperation with the connecting rod 128 connected to the first rack 124 through the first telescopic member 126, so that the armor 500 released by the cooperation of the compensation gear 115 and the arc-shaped rack 116 is lifted up from the bottom, and under the action of the positioning block 137 connected to the shaping frame 133 and located in the groove 600, the armor 500 can be quickly engaged.

[0043] In detail, during the wrapping process of the armor 500, when the compensation gear 115 and the arc-shaped rack 116 are rotated to engage and transmit, the first rotating shaft 114 rotates to release part of the armor 500, so that the armor 500 changes from a tensioned state to a relaxed state, and then the driving cylinder 122 drives the mounting column 121 to move through the output end, and the mounting column 121 drives the first rack 124 to move through the second rack 125 and the first gear 123, and the first rack 124 moves through the first telescopic member 126 and the connecting rod 128, and then under the squeezing of the connecting rod 128 and the trapezoidal block 129, the shaping seat 127 is lifted, and then the armor 500 is lifted through the shaping seat 127, and as the mounting column 121 moves, the mounting rod 131 connected to the mounting column 121 drives the shaping frame 133 to move to the top of the armor 500, at which time the second rack 125 is separated from the first gear 123, and the position of the shaping seat 127 is fixed, and then due to the obstruction The position of the shaping frame 133 is fixed by the action of the rod 1210. As the mounting column 121 continues to move, the second telescopic member 132 contracts, and the driving block 136 on the mounting column 121 moves and drives the shaping clips 135 on both sides to move in the arc groove 134. Finally, the shaping clips 135 cooperate with the shaping seat 127 to squeeze the excess armor 500 into a shape suitable for the groove 600. After the shaping is quickly completed, it is immediately reset to both sides and separated from the armor 500. The shaped part of the armor 500 is flipped to the top of the groove 600 under the drive of the first winding component 11. Due to the shape, the armor 500 cannot be automatically inserted. At this time, the driving rod 113 moves to the arc part of the guide rail 111, reducing the distance between it and the cable to avoid stretching the shaped part of the armor 500, and then the positioning block 137 is used to squeeze the armor 500 into the inside of the groove 600, and the toughness of the armor 500 itself is used to achieve automatic engagement with the groove 600.

[0044] It should be noted that the shaping clip 135 is provided with an elastic return spring for realizing automatic return, which is not shown in the figure.

[0045] Further, if Figure 7As shown, the second protection mechanism 2 includes a second winding assembly 21 disposed on the frame 100 and used for outputting the absorbent cloth 700, a releasing assembly 22 disposed on the frame 100 and used for inputting the absorbent particles 300 into the groove 600, a recovery assembly 23 disposed on the frame 100 and used for assisting the input of the absorbent particles 300, and a driving assembly 24 disposed on the recovery assembly 23 and used for driving the recovery assembly 23 to work.

[0046] In this embodiment, by setting up the second protection mechanism 2, the water-absorbing particles 300 are fixed in the groove 600 on the inner layer 200 of the composite cable by the water-absorbing cloth 700 using the second winding component 21 and the releasing component 22, and then the cable as a whole is monitored by the cooperation between the water-absorbing cloth 700 and the water-absorbing particles 300. When the outer layer 400 of the composite cable is damaged, the water enters and is conducted to the position of the water-absorbing particles 300 by the water-absorbing cloth 700, and then the water-absorbing particles 300 expand and cause the outer layer 400 of the composite cable to bulge, so that the water is controlled and will not erode to the inside, and it is convenient for the staff to find it, thereby ensuring the maintenance efficiency.

[0047] In detail, first, the second winding component 21 and the releasing component 22 cooperate to input the water-absorbing particles 300 into the groove 600 and fix the water-absorbing particles 300 through the absorbent cloth 700. During the process, the driving component 24 cooperates with the recovery component 23 to increase the contact area between the water-absorbing particles 300 and the absorbent cloth 700 and recover the excess water-absorbing particles 300 for subsequent filling work.

[0048] It should be noted that the water-absorbent cloth 700 plays a role in guiding water, and the water-absorbent particles 300 have strong water absorption and water retention properties and expand after absorbing water.

[0049] Further, if Figures 7 and 8 As shown, the second winding assembly 21 includes a rotating ring 211 connected to the frame 100, a second rotating shaft 212 connected to the rotating ring 211 and used to output the absorbent cloth 700, and a second motor 213 connected to the frame 100 and used to drive the rotating ring 211 to rotate; The release assembly 22 includes a feed box 221 connected to the frame 100 and used for quantitatively outputting the water-absorbing particles 300, a second gear 222 connected to the frame 100, a first vertical rod 225 and a second vertical rod 226 respectively connected to the frame 100 and connected through a wire 224 wound around a fixed pulley 223, a third rack 227 and a fourth rack 228 respectively connected to the first vertical rod 225 and the feed box 221 and meshing with the second gear 222 for transmission, and a first protrusion 229 and a second protrusion 2210 connected to the rotating ring 211 and used for driving the first vertical rod 225 and the second vertical rod 226 respectively.

[0050] In this embodiment, by providing a first protrusion 229 and a second protrusion 2210 connected to the rotating ring 211 and used to drive the first vertical rod 225 and the second vertical rod 226 respectively, the second winding component 21 can automatically drive the release component 22 to release the water-absorbing particles 300 and avoid the water-absorbing particles after release during the wrapping process of the absorbent cloth 700, thereby ensuring the coordination and unity of the working process and facilitating the improvement of work efficiency.

[0051] In detail, the cable covered by the armor 500 is first transferred to the position of the second protective mechanism 2, and then the second motor 213 drives the second rotating shaft 212 to rotate through the rotating ring 211, and then the absorbent cloth 700 is covered on the cable. During the process, the first protrusion 229 first drives the first vertical rod 225 to move, and then the first vertical rod 225 drives the feed box 221 to move to the top of the groove 600 through the third rack 227 and the fourth rack 228 that are meshed with the second gear 222, and quickly completes the output of the absorbent particles 300, and then the second protrusion 2210 drives the second vertical rod 226 to reset, and drives the first vertical rod 225 to reset through the silk thread 224 wound on the fixed pulley 223, and then drives the feed box 221 to reset.

[0052] Further, if Figures 9 to 11 As shown, the recovery assembly 23 includes a slide 231 connected to the frame 100, a mounting ring 232 connected to the slide 231, a first limiting frame 235 connected to the mounting ring 232 through a first elastic rope 233 and connected to a first limiting plate 234, a second limiting frame 238 connected to the mounting ring 232 through a second elastic rope 236 and connected to a second limiting plate 237, and a limiting member 239 arranged on the mounting ring 232; The limiting member 239 includes a clamping block 2392 connected to the mounting ring 232 via a first spring 2391 , a clamping slot 2393 provided on the second limiting frame 238 , and a releasing block 2394 provided on the frame 100 .

[0053] In this embodiment, by setting the first limiting plate 234 and the second limiting plate 237 in the recovery component 23, the excess water-absorbing particles 300 during input are concentrated on one side, and then the water-absorbing cloth 700 is wrapped from one side to make the water-absorbing particles 300 evenly and fully distributed under the water-absorbing cloth 700, thereby increasing the connection area between the water-absorbing particles 300 and the water-absorbing cloth 700 and promoting the improvement of the water absorption effect. At the same time, by setting the limiting member 239, the first limiting plate 234 and the second limiting plate 237 are arranged so that the excess water-absorbing particles 300 are directly transported to the next location for use.

[0054] In detail, first, when the releasing component 22 is working, more water-absorbing particles 300 than the volume of the groove 600 will be input, so that the water-absorbing cloth 700 is in full contact with the particles when covering, and the excess part is stored between the first limiting plate 234 and the second limiting plate 237. During the working process of the second winding component 21, when the water-absorbing cloth 700 flips from one side and begins to cover the groove 600 part, the driving component 24 drives the second limiting frame 238 and the second limiting plate 237 to rotate a certain angle along the circumference of the inner layer 200 of the composite cable. At the same time, under the pressure of the water-absorbing cloth 700, the first limiting plate 234 deflects a certain angle and squeezes the excess water-absorbing particles 300 to flow, so that the excess water-absorbing particles 300 form a distribution state approximately in a triangle above the groove 600, and some of the water-absorbing particles 300 fall into the recovery range of the second limiting plate 237. Then the driving component 24 drives the recovery component 24 to recover the water-absorbing cloth 700. The whole moves out from under the wrapping of the absorbent cloth 700. At this time, the absorbent cloth 700 is tightened again to cover the inner layer 200 of the composite cable, and the water-absorbing particles 300 are evenly squeezed and distributed below. Since the second limit frame 238 is deflected and the card slot 2393 thereon is engaged with the card block 2392 on the mounting ring 232 under the push of the first spring 2391, the driving component 24 cannot automatically reset after withdrawing the squeeze on the second limit frame 238. Instead, after driving the partially recovered water-absorbing particles 300 to reach the next position, the release block 2394 squeezes the card block 2392, releases the brake on the second limit frame 238, and then resets under the drive of the second elastic rope 236, and at the same time, the recovered water-absorbing particles 300 are sent into the groove 600. After the first limit plate 234 is separated from the absorbent cloth 700, it is reset together with the first limit frame 235 under the drive of the first elastic rope 233.

[0055] Further, if Fig. 9 As shown, the driving assembly 24 includes a third motor 241 connected to the slide 231, a screw 243 connected to the slide 231 and connected to an extrusion rod 242, two bevel gears 244 respectively connected to the screw 243 and the output end of the third motor 241 and meshing with each other for transmission, a reciprocating screw 246 connected to the slide 231 and connected to a ratchet gear 245, a third gear 247 connected to the output end of the third motor 241 and meshing with the ratchet gear 245 for transmission, and a force plate 248 connected to the frame 100 and connected to the reciprocating screw 246.

[0056] In this embodiment, the driving component 24 is provided so that while driving the recovery component 23 to avoid the absorbent cloth 700 laterally, the recovery component 23 can be driven to complete the recovery work, so that various actions in the working process are coordinated and coherent, which is conducive to improving work efficiency.

[0057] In detail, when the absorbent cloth 700 begins to wrap the position of the groove 600, the third motor 241 starts to rotate forward, and drives the screw 243 to rotate through the bevel gear 244, so that the extrusion rod 242 moves and squeezes the second limit frame 238. When the recovery work is completed, the third motor 241 immediately starts to rotate in the opposite direction. During the process, the extrusion frame gradually resets, and the third gear 247 drives the ratchet gear 245 to rotate, and then drives the recovery component 23 to move horizontally and separate from the absorbent cloth 700 through the reciprocating screw 246. After the absorbent cloth 700 covers the top of the groove 600, the reciprocating screw 246 drives the recovery component 23 to move again to complete the reset and start the next filling work.

[0058] It should be noted that when the reciprocating screw 246 drives the recovery assembly 23 away from the absorbent cloth 700, the extrusion frame completes half of the reset distance. When the reciprocating screw 246 drives the recovery assembly 23 back to the filling position again, the extrusion frame completes the reset work.

[0059] Further, if Figure 12 to Figure 14 As shown, the detection mechanism 3 includes a cooling component 31 disposed on the frame 100 and used to cool the cable, and a testing component 32 disposed on the cooling component 31 and used to detect cracks in the outer layer 400 of the composite cable.

[0060] It is worth mentioning here that by setting up the cooling component 31 and the testing component 32 in the detection mechanism 3, the cable can be cooled quickly after processing, and while cooling, the outer layer of the composite cable is tested by bending and twisting in all directions to ensure that the produced cable will not have undetected gaps or cracks.

[0061] In detail, after the outer layer 400 of the composite cable is processed, the cable enters the detection mechanism 3, is rapidly cooled and shaped under the action of the cooling component 31, and is detected for cracks under the action of the testing component 32.

[0062] Embodiment 2 like Figure 12 to Figure 14 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that: Further, if Figure 12 to Figure 14 As shown, the cooling component 31 includes a cooling box 312 connected to the frame 100 and having a through hole 311 on the top, a plurality of driving wheels 313 connected to the cooling box 312, a plurality of nozzles 314 respectively arranged on one side of the driving wheel 313 and between the driving wheels 313, and a pump 315 arranged on the frame 100 and connected to the plurality of nozzles 314; The test assembly 32 includes two groups of offset frames 321 connected to the cooling box 312, a torsion frame 322 connected to the offset frame 321, two groups of telescopic seats 324 connected to the torsion frame 322 through second springs 323 and used to extrude the outer layer 400 of the composite cable, a baffle 325 connected to the offset frame 321 and arranged corresponding to the telescopic seat 324, an offset rack 326 connected to the torsion frame 322, a half gear 328 connected to the cooling box 312 through a third rotating shaft 327 and meshing with the offset rack 326 for transmission, a fourth rotating shaft 329 connected to the driving wheel 313, and a belt transmission member 3210 whose two ends are respectively connected to the third rotating shaft 327 and the fourth rotating shaft 329.

[0063] In this embodiment, by providing multiple sets of driving wheels 313 and testing components 32, the outer layer of the composite cable is subjected to bending and twisting at various angles, thereby magnifying possible cracks and promoting water to enter and combine with the water-absorbing particles 300 to expand, thereby facilitating the staff to quickly detect quality problems of the cable.

[0064] In detail, first, the cable is transmitted in an S shape under the power of multiple sets of driving wheels 313, and the cable is bent multiple times, while increasing the cooling time of the cable in the cooling water. At the same time, the nozzle 314 set at the bend drives the water flow to impact the cable through the high-speed airflow, thereby promoting the penetration of water at the crack position. At the position of the test component 32, when the driving wheel 313 rotates, the half gear 328 is driven to rotate through the belt transmission member 3210, the third rotating shaft 327 and the fourth rotating shaft 329. During the rotation of the half gear 328, the torsion of the offset rack 326 connected on both sides is intermittently driven. The frame 322 rotates on the offset frame 321, and the rotation of the torsion frame 322 drives the telescopic seat 324 to rotate. One side of the telescopic seat 324 is squeezed by the baffle 325 so that it extends toward the cable and grasps the cable from both sides. The two groups of torsion frames 322 rotate in opposite directions, thereby exerting a certain torsional force on the cable to enlarge the cracks, and then cooperating with the nozzle 314 set between the driving wheels 313 to accelerate the entry of water. When the half gear 328 cancels the engagement with the offset racks 326 on both sides, the torsion frame 322 automatically resets, and the telescopic seat 324 is reset driven by the second spring 323.

[0065] It should be noted that the air pump 315 delivers gas into multiple nozzles 314 to drive the water flow to move at high speed. At the same time, the input gas forms a certain air pressure in the cooling box 312, further enhancing the entry of moisture into the cracks. The through hole 311 is used to balance the internal air pressure, and the through hole 311 can be adjusted in size; a reset spring (not shown in the figure) is arranged between the torsion frame 322 and the offset frame 321, which is used to drive the torsion frame 322 to reset.

During the process, the driving component 24 cooperates with the recovery component 23 to increase the contact area between the water-absorbing particles 300 and the water-absorbing cloth 700 and recover the excess water-absorbing particles 300 for subsequent filling work; Step 4, the testing process, after completing the coating of the absorbent cloth 700, the outer layer 400 of the composite cable is shaped under the action of the extruder, and finally the cooling component 31 in the testing mechanism 3 is used to cool the entire cable at the performance testing station III, and the integrity of the outer layer is tested in conjunction with the testing component 32.
