Description

Technical Field

[0001] This utility model belongs to the field of network cable technology, specifically a highly shielded network cable. Background Technology

[0002] High-shield network cables are cables that suppress electromagnetic interference through a metal shielding layer (such as aluminum foil or copper braided mesh). Their core structure includes an independent shielding layer for each twisted pair and an outer metal sheath. They block external electromagnetic waves through reflection, absorption, and the skin effect, while preventing internal signal leakage. These cables require grounding to form a complete circuit for optimal shielding performance. They are primarily used in high-electromagnetic-interference scenarios such as industrial automation (e.g., PLC control systems, inverter communication), data centers (10 Gigabit backbone links in server rooms), medical equipment (compliant with IEC 60601-1-2 electromagnetic compatibility standards), and financial transaction systems (meeting PCI DSS data security specifications). They can significantly reduce bit error rates and improve data transmission stability. Existing high-shield network cables are prone to problems such as insufficient contact surface and loose fixation when crimped with terminals due to the hardness of the shielding layer material and the loose braiding structure. This leads to increased resistance at the connection and signal attenuation. They are especially prone to loosening under vibration or frequent plugging and unplugging scenarios, which affects the stability of transmission. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-shield network cable, comprising a network cable consisting of 4 pairs of twisted copper wires, with an aluminum foil layer wrapped around the twisted pair, the thickness of which is 0.02-0.05mm. The surface of the aluminum foil is provided with a tinned copper wire braided layer with a coverage of ≥85%. One end of the network cable is provided with a connecting terminal, and one end of the network cable is pressed into the inside of the connecting terminal. A mating sleeve is fixedly installed in the middle of the connecting terminal near the network cable, and the mating sleeve is fitted onto the surface of the network cable. One end of the network cable surface is fixedly fitted with a plug sleeve, and the plug sleeve is inserted into the inside of the mating sleeve. A transmission sleeve is fitted onto one end of the surface of the plug-in sleeve. The inner wall of the transmission sleeve has an internal thread, and one end of the outer wall of the plug-in sleeve has an external thread. The transmission sleeve is movably mounted on the surface of the transmission sleeve through the cooperation of the internal and external threads. There are two mounting grooves on both sides inside the plug-in sleeve. The two mounting grooves are used to install the transmission components. There are two positioning grooves on the inner wall of the plug-in sleeve, and two insertion holes are opened at the other end of the two plug-in sleeve surfaces. Two positioning heads are installed in the two insertion holes. The two positioning heads are adapted to the two positioning grooves. There is a transmission component at one end inside the transmission sleeve. The transmission component is connected to the two positioning heads. When the transmission sleeve rotates and moves, it will drive the two positioning heads to insert into the two positioning grooves through the transmission component.

[0005] Preferably, the surface of the transmission sleeve is fixedly equipped with a plurality of ribs at equal intervals in a ring, and the plurality of ribs have an anti-slip function.

[0006] Preferably, the transmission assembly includes a movable ring disposed inside one end of the transmission sleeve, and the movable ring is movably sleeved on the surface of the insertion sleeve. Two annular grooves are formed on the circumferential surface of the movable ring. Two slip rings are fixedly installed on the inner wall of one end of the transmission sleeve, and the two slip rings are slidably installed inside the two annular grooves.

[0007] Preferably, two strip-shaped openings are symmetrically opened in the middle of the surface of the plug sleeve, and two connecting blocks are symmetrically fixedly installed on the inner wall of the moving ring. The two connecting blocks pass through the two strip-shaped openings and extend into the interior of the two mounting grooves on the side that is close to each other. Pushing strips are fixedly installed on the side that is close to each other, and one end of the two pushing strips is provided with a bevel.

[0008] Preferably, one end of the push bar is closely attached to a contact head, which is semi-circular. The two contact heads are fixedly mounted with plug rods on opposite sides via an extrusion plate. The two plug rods are movably inserted into the two insertion holes.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator passes one end of the network cable through the docking sleeve and inserts it into the connecting terminal to press and fix it, while simultaneously inserting the plug sleeve into the docking sleeve; then, the operator rotates the transmission sleeve to rotate and move on the surface of the plug sleeve. When the plug sleeve rotates and moves, it drives the two slip rings to rotate inside the two ring grooves, and simultaneously pushes the moving ring to move, so that the moving ring can be pushed to move horizontally without driving the moving ring to rotate. When the moving ring moves, it drives the two connecting blocks to move along the inside of the two strip openings. When the two connecting blocks move, they drive the two pushing strips to move. When the two push bars move, they drive the limiting slider to slide within the limiting groove, increasing the stability of the two push bars' movement. As the two push bars move, they push the two plug rods back-to-back within the two sockets via two contact heads and two extrusion discs, simultaneously compressing the two telescopic springs. When the two plug rods move back-to-back, they drive the two positioning heads into the two positioning grooves for fixed positioning, thereby strengthening the stability of the connection between the network cable and the connecting terminal. This allows the highly shielded network cable to be further reinforced after being crimped with the terminal, increasing the stability of the connection between the network cable and the connecting terminal and ensuring the stability of the transmission between the network cable and the connecting terminal.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0014] Depend on Figures 1 to 5 The present invention includes a network cable 1, which is composed of four pairs of twisted copper wires. The twisting density cancels out some electromagnetic interference. An aluminum foil with a thickness of 0.02-0.05mm is wrapped around the outside of the twisted pair. It has good flexibility, low cost, and good shielding performance. The surface of the aluminum foil is provided with a tin-plated copper wire braided layer with a coverage of ≥85%, which has high mechanical strength, strong tensile strength, and further improves the shielding ability. One end of the network cable 1 is provided with a connecting terminal 2. One end of the network cable 4 is pressed into the inside of the connecting terminal 2, thereby realizing the electrical connection and initial fixation between the two. A mating sleeve 3 is fixedly installed in the middle of the connecting terminal 2 near the side of the network cable 1, and the mating sleeve 3 is sleeved on the surface of the network cable 1. One end of the surface of the network cable 1 is fixedly sleeved with a plug sleeve 4, which is adapted to the mating sleeve 3 and is inserted into the mating sleeve 3. A transmission sleeve 5 is fitted onto one end of the surface of the insertion sleeve 4. The inner wall of the transmission sleeve 5 has an internal thread, and one end of the outer wall of the insertion sleeve 4 has an external thread. The transmission sleeve 5 is movably mounted on the surface of the insertion sleeve 4 through the engagement of the internal and external threads, allowing the transmission sleeve 5 to rotate and move on the surface of the insertion sleeve 4 and to be locked. Mounting grooves 22 are provided on both sides of the inside of the insertion sleeve 4 for mounting transmission components. Two positioning grooves 7 are provided on the inner wall of the connecting sleeve 3, symmetrically arranged. Two insertion holes 8 are provided at the other end of the surfaces of the two insertion sleeves 4, and two positioning... The head 9 has two positioning heads 9 that are adapted to two positioning slots 7. The two positioning heads 9 can be inserted into the two positioning slots 7 for limiting and fixing. One end of the transmission sleeve 5 is provided with a transmission component, which is connected to the two positioning heads 9. When the transmission sleeve 5 rotates and moves, it will drive the two positioning heads 9 to insert into the two positioning slots 7 through the transmission component, thereby further reinforcing the connection between the network cable 1 and the connection terminal 7. Several ribs 6 are fixedly installed in a ring at equal intervals on the surface of the transmission sleeve 5. The ribs 6 have an anti-slip function and facilitate the operator to rotate the transmission sleeve 5.

[0015] In use, the operator passes one end of the network cable 1 through the mating sleeve 3 and inserts it into the connecting terminal 2 to press and fix it in place, while simultaneously inserting the plug sleeve 4 into the mating sleeve 3; then, the operator rotates the transmission sleeve 5 to rotate and move on the surface of the plug sleeve 4. When the plug sleeve 4 rotates and moves, it drives the transmission component to operate. When the transmission component operates, it drives the two positioning heads 9 to engage with the two positioning slots 7 for fixing and limiting, thereby strengthening the stability of the connection between the network cable 1 and the connecting terminal 2. This allows the high-shielded network cable to be further reinforced after being crimped with the terminal, thereby increasing the stability of the connection between the network cable 1 and the connecting terminal 2 and ensuring the stability of the transmission between the network cable 1 and the connecting terminal 2.

[0016] The transmission assembly includes a movable ring 10 disposed inside one end of the transmission sleeve 5, and the movable ring 10 is movably sleeved on the surface of the insertion sleeve 4. Two annular grooves 12 are formed on the circumferential surface of the movable ring 10. Two slip rings 11 are fixedly installed on the inner wall of one end of the transmission sleeve 5. The two slip rings 11 are slidably installed inside the two annular grooves 12, so that the two slip rings 11 can rotate and slide inside the two annular grooves 12. Two strip-shaped openings 21 are symmetrically opened in the middle of the surface of the plug sleeve 4. Two connecting blocks 13 are symmetrically fixedly installed on the inner wall of the moving ring 10. The two connecting blocks 13 pass through the two strip-shaped openings 21 and extend into the interior of the two mounting grooves 22 on the side that is close to each other. The two connecting blocks 13 can move along the two strip-shaped openings 21. Pushing strips 14 are fixedly installed on the side that is close to each other of the two connecting blocks 13. One end of each of the two pushing strips 14 is provided with a bevel. The bevel design allows for smooth pushing. Limiting sliders 15 are fixedly installed on the end of each of the two pushing strips 14 on the side that is close to each other. Limiting grooves 16 are opened on the inner wall of one side of each of the two mounting grooves 22. The two limiting sliders 15 are slidably installed inside the two limiting grooves 16, so that the two limiting sliders 15 can slide inside the two limiting grooves 16 to limit the movement trajectory of the two pushing strips 14.

[0017] The operator rotates the transmission sleeve 5 on the surface of the insertion sleeve 4. When the insertion sleeve 4 rotates, it drives the two slip rings 11 to rotate inside the two annular grooves 12, and at the same time pushes the moving ring 10 to move. Thus, the moving ring 10 can be pushed to translate without rotating. When the moving ring 10 moves, it drives the two connecting blocks 13 to move along the inside of the two strip openings 21. When the two connecting blocks 13 move, they drive the two pushing strips 14 to move.

[0018] One end of the push bar 14 is closely attached to the contact head 17. The contact head 17 is semi-circular to facilitate the pushing of the push bar 14. The two contact heads 17 are fixedly installed with plug rods 19 on the opposite sides of each other through the extrusion plate 18. The two plug rods 19 are movably inserted into the two insertion holes 8, so that the two plug rods 19 can move in the two insertion holes 8. The opposite ends of the two plug rods 19 are fixedly connected to the two positioning heads 9 respectively. The surface of the two plug rods 19 is covered with a telescopic spring 20. The two ends of the two telescopic springs 20 are fixedly connected to the positioning head 9 and the extrusion plate 18 respectively. When the two telescopic springs 20 release their elastic potential energy, they can push the plug rods 19 through the extrusion plate 18 to move and reset the positioning head 9.

[0019] When the two push bars 14 move, they both drive the limiting slider 15 to slide within the limiting groove 16, which increases the stability of the movement of the two push bars 14. When the two push bars 14 move, they push the two plug rods 19 to move in opposite directions within the two plug holes 8 through the two contact heads 17 and the two extrusion plates 18, and at the same time compress the two telescopic springs 20. When the two plug rods 19 move in opposite directions, they drive the two positioning heads 9 to be engaged into the two positioning grooves 7 for fixed positioning, thereby strengthening the stability of the connection between the network cable 1 and the connecting terminal 2.
