It utilizes environmentally friendly halogen-free materials (producing low smoke and being non-toxic when burned) and utilizes flame-retardant additives for fire resistance (e.g., UL 94 V-0). It also complies with Category 5e standards (1Gbps transmission). Its aluminum foil or aluminum foil + copper braid shield effectively suppresses electromagnetic interference, and its internal drain wire ensures reliable grounding.

[0014] As another preferred embodiment, the method for producing a low-smoke, halogen-free, flame-retardant Category 5e shielded data cable is applied to the device for producing a low-smoke, halogen-free, flame-retardant Category 5e shielded data cable, comprising the following steps: Step 1: Grooving step: the cable cores are input into various pre-processing mechanisms and enter the stabilizing tube. The groove cutter in the stabilizing tube opens multiple wavy grooves on the surface insulation layer. Step 2, the cable arrangement step, the cable core after slotting is positioned and stabilized in the groove by a stabilizing component, and glue is applied to the surface of the groove, and then it is input into the covering component. The placement rack in the covering component rotates continuously to wrap the shielding layer on the surface of the cable core. In this process, the cable arrangement component arranges the drain wire in the groove. At this time, when the cable arrangement rack is located on the front slide rail, the drain wire is directly arranged in the groove, and then the shielding layer is wrapped, and then the pressing part is used to compact the gaps on both sides of the drain wire.

[0032] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0033] Example 1 like Figure 1 、 Figure 2 As shown, a low-smoke, halogen-free, flame-retardant Category 5e shielded data cable production device includes: A pre-processing mechanism 1, the pre-processing mechanism 1 is used to open a wave groove in the cable core insulation layer; The coating mechanism 2 is arranged behind the pre-processing mechanism 1 and is used to arrange the drainage wire and cover the shielding layer. The coating mechanism 2 includes a stabilizing component 21 for maintaining the stability of the cable core, a wrapping component 22 arranged in the middle of the stabilizing component 21 and used to wrap the shielding layer, and a cable arranging component 23 arranged on the stabilizing component 21 and cooperating with the wrapping component 22 to arrange the drainage wire. The drainage wire is arranged on the cable core along the wave groove and then covered with the shielding layer, and the pores in the shielding layer are compacted; The cabling mechanism 3 is arranged behind the covering mechanism 2 and is used to use the wave groove to achieve complete covering of the cable core by the sheath.

[0034] The structure of a shielded data cable typically consists of an inner core, an insulation layer, a shielding layer, and a sheath. A drain wire is also provided on the shielding component of the insulation layer. The drain wire is usually placed close to the inside or outside of the shielding layer (aluminum foil or copper braid) and secured by mechanical pressing, conductive adhesive bonding, or ultrasonic welding to ensure reliable contact with the shielding layer throughout. Its core functions include providing a low-impedance grounding path to guide the discharge of static electricity and electromagnetic interference; compensating for continuity defects at the seams of the shielding layer, especially maintaining the shielding effect during bending; and simplifying terminal installation, making it easier to crimp to the connector grounding terminal and improving construction efficiency. The drain wire is mostly made of tinned copper wire, and its placement and fixing process directly affect the cable's high-frequency performance and long-term reliability.

[0035] The advantages of setting the drain wire on the inside of the shielding layer are a shorter grounding path, better electromagnetic shielding continuity, and less susceptible to damage from external forces; but the disadvantages are that it may increase the cable diameter and place higher voltage requirements on the insulation layer of the twisted wire pair. The advantages of setting it on the outside are convenient installation, stronger mechanical protection, and no impact on the internal wire pair structure; but the disadvantages are that it is easily pulled by external forces, resulting in poor contact, and the high-frequency shielding effectiveness is slightly lower. Based on this, the present application adopts an alternating arrangement of the inside and outside for the drain wire, that is, one section of the drain wire is set on the inside of the shielding layer, and one section is set on the outside of the shielding layer, which improves a certain shielding effect while reducing the possibility of being affected by external forces, making the product more comprehensive and balanced, and increasing the scope of use of the finished product.

[0036] In this embodiment, a pre-processing mechanism 1 is provided to process the insulating layer on the surface of the cable core, a plurality of wavy grooves are evenly opened on the surface, and a covering mechanism 2 is used to arrange the drainage wires in the grooves, and the shielding layer is covered alternately.

[0037] In detail, with regard to the setting of the drain line, since the shielding layer is wrapped around the outside of the cable core, when the drain line is set on the inside of the shielding layer, large gaps will appear between the two sides of the drain line and the middle of the shielding layer. When alternating between the inside and the outside, the existence of the gaps directly affects the shielding effect of the shielding layer. Therefore, on the one hand, by setting the grooves, the grooves are used to make the position of the drain line stable after arrangement, and no slipping occurs, while reducing the generation of edge gaps. On the other hand, by compacting the shielding layer, the shielding layer can be tightly attached to the surface of the drain line, thereby reducing the gaps and avoiding a major impact on the shielding effect of the shielding layer.

[0038] Further, if Figure 3 As shown, the pre-processing mechanism 1 includes a drum 11 for releasing the cable core, a stabilizing tube 12 arranged behind the drum 11, multiple groups of stabilizing rings 13 arranged inside the stabilizing tube 12, multiple balls evenly arranged on the stabilizing rings 13, and a slotted part 14 arranged in the middle of each group of stabilizing rings 13.

[0039] Further, if Figure 4 、 Figure 5 As shown, the slotting member 14 includes a control ring 141 rotatably connected to the stabilizing tube 12, multiple sets of swing rods 142 provided on the control ring 141, slotting knives 143 rotatably connected to the ends of the swing rods 142, and two sets of gear rings 144 fixed on both sides of the upper ends of the slotting knives 143; The utility model further comprises a collecting roller 145 arranged in front of the slotting knife 143 and a cutting knife 146 slidably connected above the collecting roller 145 .

[0040] In this embodiment, a plurality of evenly distributed wave grooves are evenly opened on the surface of the cable by providing a slotting member 14. During the slotting process, the cable core is kept stable to ensure the shaping effect of the slots.

[0041] In detail, the cable core is input into the stabilizing tube 12, and the balls on the stabilizing ring 13 are used to keep the cable core stable during the movement. The control ring 141 rotates back and forth on the stabilizing tube 12, driving the mounted slotting knife 143 to swing left and right, and cooperating with the movement of the cable, so that the slotting knife 143 can slide in a wave-like manner on the surface of the cable core. During the slotting process, the tip of the slotting knife 143 needs to cooperate with the moving direction. Therefore, toothed rings 144 are provided on both sides of the upper section of the slotting knife 143, and two gears are provided on the upper end of the slotting knife 143. The gears are engaged with the toothed rings 144. The left and right swing of the slotting knife 143 is used to make the tip of the slotting knife 143 change in real time to cater to the slotting direction. At the same time, multiple sets of slotting parts 14 are provided, and the accuracy of the slotting knife 143 on the slotting part 14 is gradually improved, so that multiple slots are made to finally form a complete groove. Through multiple slotting, the shape of the groove is guaranteed to be stable.

[0042] It should be noted that since the slotting knife 143 will cut the insulation layer and generate waste, the accumulation of waste will affect the forming effect of the groove. Therefore, a collecting roller 145 and a cutter 146 are set. A protrusion is set on the surface of the collecting roller 145. When the collecting roller 145 rotates, the cut strip waste can be rolled onto the collecting roller 145, and then the cutter 146 cuts it off, chopping the waste into small particles. An opening is set at the lower end of the stabilizing tube 12 so that the waste can fall from the opening, thereby avoiding affecting the normal slotting steps.

[0043] The wavy grooves are provided so that the drainage lines are arranged along the wavy shape, which can effectively prevent the drainage lines from being broken due to cable bending.

[0044] Further, if Figure 6 、 Figure 7 As shown, the stabilizing assembly 21 includes multiple groups of positioning rollers 211 arranged behind the stabilizing tube 12, two groups of stabilizing rollers 212 arranged behind the positioning rollers 211, a positioning tube 213 arranged between the two groups of stabilizing rollers 212, multiple groups of connecting blocks 214 rotatably connected to the front end of the positioning tube 213, a gluing rod 215 slidably connected to the connecting block 214, and a gluing bead 216 arranged at the end of the gluing rod 215.

[0045] In this embodiment, by providing a stabilizing roller 212 and a positioning tube 213 , the cable core is ensured to remain stable during the coating process, while the grooves are positioned and the surface glue is applied.

[0046] In detail, the cable core after slotting is turned by the positioning roller 211 and then wound onto the stabilizing roller 212. Two groups of stabilizing rollers 212 are set and are located on the front and rear sides of the coating mechanism 2 respectively. The cable core is wound onto the stabilizing roller 212. As the stabilizing roller 212 rotates, one end is wound in and the other end is released. The stabilizing roller 212 is used to achieve uniform movement of the cable core and prevent the cable core from sagging in the middle due to being too long, affecting the wiring in the middle. Then the cable core passes through the connecting block 214, and the glue bead 216 at the end of the glue rod 215 contacts the groove. Since the groove is wavy, the connecting block 214 is rotatably connected to the positioning tube 213 and the glue rod 215 is slidably connected to the connecting block 214, so that the glue rod 215 can swing following the position of the groove.

[0047] It should be noted that the glue coating rod 215 is connected to the rubber hose at the rear, and the glue coating bead 216 is rotated to coat glue on the surface of the groove, wherein the glue can be conductive glue.

[0048] It is worth mentioning that the position of the groove can be positioned by the swing rod 142. After a fixed distance, the positions of the corresponding grooves can correspond one to one, so the position of the grooves can be positioned during subsequent wiring.

[0049] Further, if Figure 8 As shown, the wrapping assembly 22 includes a rotating bracket 221 arranged behind the positioning tube 213, a placement rack 222 rotatably connected to the rotating bracket 221, a slide 223 fixed on the radial inner side of the placement rack 222, a pressure block 224 slidably connected to the slide 223, a pressure roller 225 arranged on the pressure block 224, and a glue coating roller 226 arranged on the inner side of the pressure roller 225.

[0050] In this embodiment, the cable core passes through the rotating bracket 221, and the aluminum foil is placed on the placement rack 222. The placement rack 222 rotates continuously. A spring is provided on the slide 223 to press the pressure block 224. The pressure roller 225 on the pressure block 224 presses the aluminum foil to prevent the aluminum foil from spreading during the wrapping process. The aluminum foil wrapped on the cable core passes through the glue coating roller 226 and is coated with a layer of glue at the edge. When the aluminum foil is wrapped, this layer of glue seals the edge.

[0051] Further, if Figure 9 、 Figure 10 As shown, the wire traversing assembly 23 includes a wire traversing frame 231 disposed in the middle of the rotating bracket 221, a coil bobbin 232 rotatably connected to the traversing frame and used for traversing the wire, a sliding plate 233 slidably connected to the middle of the wire traversing frame 231, a wire lead hole 234 disposed on the sliding plate 233, and a wire pressing wheel 235 rotatably connected to the lower end of the wire lead hole 234; A swing rod 236 connected to the wire rack 231 is rotatably connected, a slider 237 connected to the middle of the swing rod 236 is horizontally slidably connected, and a pressure rod 238 is fixed to the lower end of the slider 237.

[0052] The cable assembly 23 further includes slots 239 provided on both sides of the cable rack, slide rails 240 provided on both sides of the rotation, and blocks 241 slidably connected to the slide rails 240 .

[0053] In this embodiment, by setting the lead hole 234 and the wire pressing wheel 235, the drainage wire on the coil tube 232 passes through the lead hole 234 on the sliding plate 233, enters the middle of the wire pressing wheel 235, and is pressed into the groove by the wire pressing wheel 235 to realize the arrangement of the drainage wire.

[0054] In detail, the sliding plate 233 is driven to slide horizontally by a screw rod and other devices, thereby cooperating with the position of the groove and adjusting the position of the wire pressing wheel 235. At the same time, the wire pressing wheel 235 is rotated and connected under the wire guide hole 234, so that the wire pressing wheel 235 can fully cooperate with the position and angle of the groove, thereby ensuring that the drainage line is arranged in the groove according to the estimation of the groove.

[0055] By means of the slots 239 provided on both sides of the wire rack 231, the block 241 connected to the slide rail 240 can be snapped into the slots 239 by means of the cylinder control, so that when the block 241 slides, the lead rack is pulled from the front slide rail 240 to the rear slide rail 240, that is, when the lead rack is located on the front slide rail 240, the lead rack first arranges the drain wire on the groove and then wraps it with aluminum foil. At this time, the drain wire is wrapped with aluminum foil and is located inside the shielding layer. Then the block 241 on the rear slide rail 240 moves, and the block 241 is snapped in. The lead frame 231 is fixed in the card slot 239, and the wire rack 231 is pulled onto the rear slide rail 240. The wire rack 231 passes through the wrapping component 22. At this time, the aluminum foil is wrapped first and then the wire is arranged. It should be noted that at this time, the aluminum foil wraps the groove, so a swing rod 236 and a pressure rod 238 are set. After the lead frame is moved into place, the swing rod 236 swings down, so that the lower end of the pressure rod 238 is embedded in the groove, pressing the aluminum foil down to the surface of the groove. At the same time, a ball can also be set at the lower end of the pressure rod 238 for coating glue on the surface to achieve adhesion of the flow line.

[0056] It should be noted that by switching the position of the cable rack 231, the position of the drain wire arrangement and the shielding layer is switched. During the switching process, the shielding layer is adhered to the surface of the cable core, reducing the appearance of gaps and avoiding the weakening of the shielding effectiveness.

[0057] Further, if Figure 11As shown, the cable assembly 23 includes a pressing part 242 arranged on the slide rail 240, and the pressing part 242 includes a pressing tube 251 arranged behind the rotating bracket 221, a fixed roller 252 fixed at the front end of the pressing tube 251, a shaking block 253 rotatably connected to the lower end of the pressing tube 251 behind the fixed roller 252, a control rod 254 rotatably connected to the upper part of the pressing tube 251, a movable frame 255 vertically slidably connected to the end of the control rod 254, and a pressing rod 256 fixed at the lower end of the movable frame 255.

[0058] In this embodiment, by providing a pressing piece 242, the aluminum foil is further pressed onto the cable core surface, that is, when the groove position for arranging the drain line and the drain line are arranged inside the shielding layer, the pores on both sides of the drain line are compacted.

[0059] In detail, the cable enters the pressing tube 251, and is fixed and pressed down by the fixing roller 252, so that the grass at the lower end of the cable core can fully contact the shaking block 253. The shaking block 253 is connected to the lower part of the pressing tube 251 through a spring rotation. At the same time, a protrusion is provided on the inside, which can penetrate into the groove on the surface of the cable core, compact the aluminum foil on the surface, and fit tightly to the surface of the groove, using the spring to match the wave shape of the groove.

[0060] When the drain wire is wrapped inside the shielding layer, the lower portion of the drain wire is located in the groove, leaving a gap between the upper and lower portions of the aluminum foil. Control rod 254 controls pressing rod 256 to press against both sides of the drain wire, applying pressure to the aluminum foil on both sides of the drain wire, thereby tightly attaching the aluminum foil to the drain wire and preventing any gaps. The aluminum foil has a certain degree of ductility, so to prevent damage, the ends of pressing rod 256 are spherical.

[0061] Further, if Figure 12 、 Figure 13 As shown, the cabling mechanism 3 includes an extruder 31 arranged behind the coating mechanism 2 and a winder 32 arranged behind the extruder 31, and also includes a bunching tube 331 arranged behind the coating mechanism 2, a discharge tube 332 arranged in the middle of the bunching tube 331, a forming tube 333 arranged behind the bunching tube 331, multiple groups of rubber sleeves 334 arranged at the rear end of the forming tube 333, and an extrusion ring 335 arranged on the outside of the rubber sleeve 334 and rotatably connected to the forming tube 333.

[0062] In this embodiment, the forming tube 333 is provided to assist in the forming of the sheath so that the sheath can fully fill the middle of the cable core during the forming process, thereby fully protecting the cable.

[0063] In detail, the cable core passes through the bundling tube 331 and enters the forming tube 333. At the same time, the discharge tube 332 outputs the rubber material to the middle forming tube 333 to constrain each group of cable cores to ensure that the position of the cable core is fixed. Then, the extrusion ring 335 is continuously rotated to extrude the internal rubber sleeve 334, so that the rubber material in the middle can be filled into the middle of the cable, and then input into the extruder 31 to complete the final molding of the sheath.

[0064] It should be noted that, since wavy grooves are provided on the cable core, on the one hand, these grooves are used to make the connection between the sheath and the cable core tighter, avoiding separation between the shielding layer and the sheath during use, which causes the drainage lines and the shielding layer to be misaligned. On the other hand, the grooves can be used to add excess rubber to the middle of the cable core for filling. The excess rubber can be squeezed out from the pores of the grooves, which will not make the distance between the cable cores farther, resulting in position deviation, and a certain cable core being closer to the edge.

[0065] Example 2 like Figure 14 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that: Further, if Figure 14 As shown, the method for producing a low-smoke, halogen-free, flame-retardant Category 5e shielded data cable is applied to the device for producing a low-smoke, halogen-free, flame-retardant Category 5e shielded data cable, and comprises the following steps: Step 1, the grooving step, the cable cores are respectively input into the respective pre-processing mechanisms 1 and enter the stabilizing tube 12, and pass through the grooving knife 143 in the stabilizing tube 12 to open a plurality of wavy grooves on the surface insulation layer.

[0066] Step 2, the cable arrangement step, the cable core after the groove is positioned and stabilized by the stabilizing component 21, and glue is applied to the surface of the groove, and then it is input into the covering component, and the placement rack 222 in the covering component rotates continuously to wrap the shielding layer on the surface of the cable core. In this process, the cable arrangement component 23 arranges the drain wire in the groove. At this time, when the cable arrangement rack 231 is located at the front slide rail 240, the drain wire is directly arranged in the groove, and then the shielding layer is wrapped, and then the pressing piece 242 is used to compact the gaps on both sides of the drain wire. After a period of time, the drain rack moves backward. At this time, the shielding layer is first wrapped on the cable surface, and then the shielding layer is pressed tightly to make the shielding layer fit the groove, and then the cable arrangement component 23 is used to arrange the drain wire on the outer layer of the shielding layer; Step three is the cabling step. The shielded and wrapped multiple cable cores are input into the cabling mechanism 3. While entering the forming tube 333, the sheath rubber is input into the middle through the rubber outlet hose. The cable core is extruded by the rubber sleeve 334 so that the rubber in the middle can completely fill the pores in the middle of the cable core.
