[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Example 1
[0031] Please see Figures 1-7As shown, a flat, single-pair Ethernet digital communication cable includes a conductor 1; a protective connection mechanism is provided on the outer side of the conductor 1. Existing Ethernet digital communication cables are mostly circular in design, making it difficult to maintain a close fit with the ground during laying, easily causing rolling. During long-distance laying, the cable is prone to twisting, leading to cracks under prolonged torsional forces and significantly impacting its lifespan. The flat design of the cable allows for a closer fit with the ground, preventing excessive twisting. The protective connection mechanism includes an inner protective layer 21, an insulation layer 22, a shielding layer 23, an armor layer 24, filler 25, an inner sheath 26, an intermediate layer 27, and an outer sheath 28. 8. A connecting assembly is provided. The inner protective layer 21 is sleeved on the outside of the conductor 1. An insulating layer 22 is sleeved on the outside of the inner protective layer 21. A shielding layer 23 is sleeved on the outside of the insulating layer 22. An armor layer 24 is wound around the outside of the shielding layer 23. A filler 25 is provided on the outside of the armor layer 24. The filler 25 fills the inside of the inner sheath 26, and the inner sheath 26 is sleeved on the outside of the filler 25. An intermediate layer 27 is sleeved on the outside of the inner sheath 26. An outer sheath 28 is sleeved on the outside of the intermediate layer 27. A connecting assembly is provided at the end of the conductor 1. The inner protective layer 21 is made of nylon. The use of nylon material for the inner protective layer 21 provides insulation, preventing current from flowing outward from the conductor 1. Because nylon material has wear-resistant properties, it is not easily damaged during prolonged contact and friction with conductor 1, effectively providing insulation. The insulation layer 22 is made of cross-linked polyethylene, which further enhances the insulation effect on conductor 1 and protects it. Cross-linked polyethylene has excellent mechanical properties and can effectively withstand bending and impact to protect conductor 1. The shielding layer 23 is made of copper foil, which isolates electromagnetic signals, preventing electromagnetic signals emitted by one group of conductors 1 from affecting other conductors 1. The filler 25 is made of neoprene rubber. The neoprene rubber filler 25 improves the overall fire resistance of the cable. The inner sheath 26 is made of polyester braided yarn, which further enhances the overall strength of the cable. The intermediate layer 27 is made of alumina film, which further enhances the overall fire resistance of the cable and increases the time the cable can withstand open flames. The outer sheath 28 is made of PUR material, which enhances the wear resistance of the outer side of the cable and prevents damage caused by friction with soil or ground during long-term use.
[0032] Furthermore, the connecting assembly includes a fixed base 29, a connecting base 31, a movable cavity 32, a screw 33, a transmission assembly, a screw sleeve 46, a storage groove 47, a connecting block 48, a connecting groove 49, and a fixing assembly. The fixed base 29 is fixedly connected to the upper and lower ends of the rear side of the conductor 1, and the upper and lower ends of the front side of the conductor 1 are both fixedly connected to the connecting base 31. The movable cavity 32 is opened on the rear side of the fixed base 29, and the front end of the screw 33 is rotatably connected inside the movable cavity 32. A transmission component is provided on the outer side of the front end of the screw 33. A screw sleeve 46 is threadedly connected to the outer side of the rear end of the screw 33. The screw sleeve 46 is fixedly connected to the inner wall of the storage groove 47. The storage groove 47 is opened at the front end of the connecting block 48. The front end of the connecting block 48 is sleeved inside the movable cavity 32, and the rear end of the connecting block 48 is inserted into the inside of the connecting groove 49. The connecting groove 49 is opened at the front end of the connecting seat 31. A fixing component is provided between the bottom end of the inner wall of the connecting groove 49 and the connecting block 48.
[0033] Furthermore, a slider 51 is fixedly connected to the bottom end of the front end of the connecting block 48. The slider 51 is slidably connected inside the slide groove 52, which is located at the bottom end of the inner wall of the movable cavity 32. During operation, when the connecting block 48 moves, the slider 51, which is fixedly connected to the connecting block 48, slides synchronously inside the slide groove 52. The combined action of the slider 51 and the slide groove 52 limits the movement distance of the connecting block 48, preventing the connecting block 48 from completely dislodging from the inside of the movable cavity 32 due to excessive movement, which would cause the screw sleeve 46 to dislodge from the outside of the screw 33, and the screw 33 to dislodge from the inside of the receiving groove 47.
[0034] Furthermore, the transmission assembly includes a worm gear 34, a worm 35, a rotating groove 36, a first bevel gear 37, a second bevel gear 38, a transmission cavity 39, and a transmission shaft 41. The worm gear 34 is fixedly connected to the outer side of the front end of the screw 33. The worm gear 34 cooperates with the worm 35. The worm 35 is rotatably connected inside the rotating groove 36. When the worm gear 34 rotates, it drives the fixedly connected screw 33 to rotate synchronously, thereby causing the threaded sleeve 46 on the outer side of the threaded screw 33 to move, which in turn drives the connecting block 48 to move synchronously, so that the connecting block 48 is inserted into the interior of the connecting groove 49. The connection between the two sets of conductors 1 is fixed by the fixing assembly. The rotating groove 36 is opened at the top end of the front side of the inner wall of the movable cavity 32. The first bevel gear 37 is fixedly connected to the right side of the worm 35, and the first bevel gear 37 is disposed inside the transmission cavity 39. When the first bevel gear 37 rotates, it drives the fixedly connected worm 35 to rotate synchronously. The rotation causes the worm gear 34, which cooperates with the worm 35, to rotate. The transmission cavity 39 is opened on the inner wall of the movable cavity 32 and is connected to the rotating groove 36. The first bevel gear 37 and the second bevel gear 38 mesh. The rotation of the second bevel gear 38 drives the meshing first bevel gear 37 to rotate synchronously. The top of the second bevel gear 38 is fixedly connected to the transmission shaft 41. The top of the transmission shaft 41 passes through the fixed seat 29 and extends to the outside of the fixed seat 29. When it is necessary to reinforce the connection between the two sets of conductors 1, the knob 42 is rotated to drive the second bevel gear 38 to rotate through the transmission shaft 41. During operation, when it is necessary to release the fixation between the two sets of conductors 1, the limiting of the connecting block 48 by the fixing component is first released, and then the knob 42 is rotated in the opposite direction to move the connecting block 48 into the interior of the movable cavity 32. The screw 33 is inserted into the interior of the receiving groove 47 to release the reinforcement of the connection between the two sets of conductors 1.
[0035] Furthermore, a knob 42 is fixedly connected to the top of the transmission shaft 41. The knob 42 facilitates the rotation of the first bevel gear 37. An anti-slip sleeve 43 is glued to the outside of the knob 42. The anti-slip sleeve 43 is made of rubber, which increases the friction. The anti-slip sleeve 43 has anti-slip texture on its outside, which further increases the friction and prevents the knob 42 from slipping due to insufficient friction when it is rotated.
[0036] Furthermore, a threaded sleeve 44 is fitted on the outer side of the drive shaft 41. The bottom end of the threaded sleeve 44 is fixedly connected to the top end of the fixed seat 29, and a nut 45 is threadedly connected to the outer side of the threaded sleeve 44. During operation, when it is necessary to reinforce the connection between the two sets of conductors 1, the nut 45 is first rotated to loosen it, so that the inner wall of the threaded sleeve 44 is released from the tight fit with the outer side of the drive shaft 41, thus releasing the effect of limiting the rotation of the drive shaft 41. At this time, the connection between the two sets of conductors 1 can be reinforced. After the reinforcement of the connection between the two sets of conductors 1 is completed, the nut 45 is tightened again, so that the inner wall of the threaded sleeve 44 is tightly fitted with the outer side of the drive shaft 41, and the rotation of the drive shaft 41 is limited by friction.
[0037] Furthermore, the fixing assembly includes a fixing groove 53, a fixing block 54, a fixing cavity 55, and a return spring 56. The fixing groove 53 is formed on the rear side of the bottom end of the connecting block 48, and the fixing groove 53 engages with the fixing block 54. The bottom end of the fixing block 54 is sleeved inside the fixing cavity 55. The fixing cavity 55 is formed on the inner wall of the connecting groove 49 near the rear side. The fixing cavity 55 is provided with a return spring 56 inside. The top end of the return spring 56 is fixedly connected to the bottom end of the fixing block 54, and the bottom end of the return spring 56 is fixedly connected to the inner wall of the fixing cavity 55. When the connecting block 48 is inserted into the connecting groove 49, the connecting block 48 compresses the inclined surface formed on the fixing block 54, causing the fixing block 54 to be subjected to compressive force. The connecting block 48 moves downward into the fixed cavity 55 and compresses the return spring 56, causing the return spring 56 to undergo elastic deformation. When the connecting block 48 is fully inserted into the connecting groove 49, the compressive force of the connecting block 48 on the fixed block 54 disappears. At this time, the fixed block 54 returns to its original position under the restoring force of the return spring 56 and inserts into the fixed groove 53, engaging with the fixed groove 53. This limits the movement of the connecting block 48 and reinforces the connection between the two sets of conductors 1. The rear side of the fixed block 54 has an abutment groove 59, which cooperates with the abutment block 61. The abutment block 61 is sleeved inside the sleeve groove 62, which is located on the rear side of the fixed cavity 55 and is connected to the fixed cavity 55. A baffle 67 is fixedly connected to the rear side of the abutment block 61. A movable groove 63 is provided at the top of the abutment block 61. A guide rod 64 is fixedly connected inside the movable groove 63. A movable block 65 is sleeved on the outside of the guide rod 64, and a compression spring 66 is wound around the outside of the guide rod 64. The side of the compression spring 66 near the movable block 65 is fixedly connected to the movable block 65, and the side of the compression spring 66 away from the movable block 65 is fixedly connected to the inner wall of the movable groove 63. When the limiting position of the fixing block 54 on the connecting block 48 is to be released, the baffle 67 is first pressed against the connecting seat 31. Under the action of the pressing force, the baffle 67 and the abutment block 61 move towards the fixing block 54. The abutment block 61 is inserted into the abutment groove 59 and the fixing block 54 is locked. The compression causes the fixing block 54 to move into the fixing cavity 55, releasing the fixing block 54 from the fixing groove 53 and thus releasing the limiting effect on the connecting block 48. At this time, the effect of fixing the connection between the two sets of conductors 1 is released. When the abutment block 61 is inserted into the abutment groove 59, the moving block 65 slides synchronously with the abutment block 61 in the moving groove 63 and compresses the compression spring 66, causing the compression spring 66 to undergo elastic deformation. When the pressing on the baffle 67 stops, the baffle 67 and the abutment block 61 return to their original positions under the restoring force of the compression spring 66, releasing the compression on the fixing block 54 and preventing the movement of the fixing block 54 from being blocked when the connection between the two sets of conductors 1 needs to be reinforced again in the future.
[0038] Furthermore, a movable block 57 is fixedly connected to the bottom of the front side of the fixed block 54. The movable block 57 is slidably connected inside the movable groove 58, which is located on the front side of the inner wall of the fixed cavity 55. During operation, when the fixed block 54 moves, the movable block 57, which is fixedly connected to the fixed block 54, slides synchronously inside the movable groove 58. The combined action of the movable block 57 and the movable groove 58 limits the movement distance of the fixed block 54, preventing the fixed block 54 from moving excessively under the restoring force of the return spring 56 and thus dislodging from the inside of the fixed cavity 55.
[0039] Working Principle: Existing Ethernet digital communication cables are mostly circular in design, making it difficult to adhere to the ground during laying and prone to rolling. Over long distances, this can cause the cable to twist, leading to cracks under prolonged torsional stress and significantly impacting its lifespan. The flat cable design allows for a closer fit to the ground, preventing excessive twisting. The inner protective layer 21 made of nylon provides insulation, preventing current from flowing outwards from the conductor 1. Furthermore, the wear-resistant properties of nylon prevent damage during prolonged contact and friction with the conductor 1, effectively providing insulation. The cross-linked polyethylene insulation layer 22 further enhances the insulation of the conductor 1 and provides protection. Polyethylene has excellent mechanical properties, effectively protecting conductor 1 from bending and impact. The copper foil shielding layer 23 isolates electromagnetic signals, preventing electromagnetic signals emitted by one group of conductors 1 from affecting other conductors 1. The neoprene rubber filler 25 improves the overall fire resistance of the cable. The polyester braided inner sheath 26 further enhances the overall strength of the cable. The alumina film intermediate layer 27 further enhances the overall fire resistance of the cable, increasing the time it can withstand open flames. The PUR outer sheath 28 enhances the abrasion resistance of the cable's outer surface, preventing damage caused by friction with soil or the ground during long-term use.
[0040] When reinforcing the connection between the two sets of conductors 1, first loosen the nut 45 by rotating it, so that the inner wall of the threaded sleeve 44 is no longer tightly fitted with the outer side of the drive shaft 41, thus releasing the effect of limiting the rotation of the drive shaft 41. At this time, the connection between the two sets of conductors 1 can be reinforced. After the reinforcement of the connection between the two sets of conductors 1 is completed, tighten the nut 45 again, so that the inner wall of the threaded sleeve 44 is tightly fitted with the outer side of the drive shaft 41, and the rotation of the drive shaft 41 is limited by friction.
[0041] When reinforcing the connection between the two sets of conductors 1, rotating the knob 42 drives the second bevel gear 38 to rotate via the transmission shaft 41. The rotation of the second bevel gear 38 drives the meshing first bevel gear 37 to rotate synchronously. When the first bevel gear 37 rotates, it drives the fixedly connected worm gear 35 to rotate synchronously, causing the worm wheel 34 that cooperates with the worm gear 35 to rotate. When the worm wheel 34 rotates, it drives the fixedly connected screw 33 to rotate synchronously, thereby causing the threaded sleeve 46 on the outside of the threaded screw 33 to move synchronously, causing the connecting block 48 to move synchronously, so that the connecting block 48 is inserted into the interior of the connecting groove 49. The connection between the two sets of conductors 1 is fixed by the fixing component. When it is necessary to release the fixation between the two sets of conductors 1, first release the limiting position of the fixing component on the connecting block 48, and then rotate the knob 42 in the opposite direction to move the connecting block 48 into the interior of the movable cavity 32. The screw 33 is then inserted into the interior of the receiving groove 47, thus releasing the reinforcement of the connection between the two sets of conductors 1.
[0042] When the connecting block 48 moves, the slider 51, which is fixedly connected to the connecting block 48, slides synchronously inside the slide groove 52. The combined action of the slider 51 and the slide groove 52 limits the movement distance of the connecting block 48, preventing the connecting block 48 from completely dislodging from the inside of the movable cavity 32 due to excessive movement, which would cause the screw sleeve 46 to dislodge from the outside of the screw 33 and the screw 33 to dislodge from the inside of the receiving groove 47.
[0043] When the connecting block 48 is inserted into the connecting groove 49, the connecting block 48 presses against the inclined surface on the fixing block 54, causing the fixing block 54 to move into the fixing cavity 55 under the pressure and press against the return spring 56, causing the return spring 56 to undergo elastic deformation. When the connecting block 48 is fully inserted into the connecting groove 49, the pressure of the connecting block 48 on the fixing block 54 disappears. At this time, the fixing block 54 returns to its original position under the restoring force of the return spring 56 and inserts into the fixing groove 53, engaging with the fixing groove 53, thus limiting the movement of the connecting block 48 and reinforcing the connection between the two sets of conductors 1.
[0044] When the fixed block 54 moves, the movable block 57, which is fixedly connected to the fixed block 54, slides synchronously inside the movable groove 58. The combined action of the movable block 57 and the movable groove 58 limits the movement distance of the fixed block 54, preventing the fixed block 54 from moving excessively under the restoring force of the return spring 56 and thus dislodging from the inside of the fixed cavity 55.
[0045] When the limiting effect of the fixing block 54 on the connecting block 48 is to be released, the baffle 67 is first pressed against the connecting seat 31. Under the action of the pressing force, the baffle 67 and the abutment block 61 move towards the fixing block 54. The abutment block 61 inserts into the abutment groove 59 and squeezes the fixing block 54, pushing the fixing block 54 into the fixing cavity 55, so that the fixing block 54 is released from the state of being locked with the fixing groove 53, thus releasing the limiting effect on the connecting block 48. At this time, the effect of fixing the connection between the two sets of conductors 1 is released. In addition, when the abutment block 61 is inserted into the abutment groove 59, the moving block 65 slides synchronously with the abutment block 61 in the moving groove 63 and compresses the compression spring 66, causing the compression spring 66 to undergo elastic deformation. When the pressing on the baffle 67 stops, the baffle 67 and the abutment block 61 return to their original positions under the restoring force of the compression spring 66, releasing the compression on the fixed block 54 and preventing the fixed block 54 from being blocked when the connection between the two sets of conductors 1 needs to be reinforced again in the future.
[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
