Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to an ultra-flexible shielded cable. Background Technology

[0002] In the field of modern electronics and communication technology, with the continuous miniaturization and integration of semiconductor devices, increasingly higher requirements are being placed on the cables connecting these devices. Especially in high-temperature and high-electromagnetic-interference environments, traditional cables often struggle to meet the multiple demands of high-current transmission, high-frequency signal transmission, and electromagnetic shielding.

[0003] Traditional shielded cables typically use ordinary copper conductors and conventional insulation materials such as polyvinyl chloride (PVC). These materials are prone to aging in high-temperature environments, leading to a decline in cable performance and even safety hazards. Furthermore, the shielding layer of these cables often uses copper mesh or copper foil, which provides some shielding effect, but its shielding efficiency is limited when facing high-frequency electromagnetic interference, making it difficult to guarantee stable signal transmission.

[0004] Furthermore, with the increasing compactness of semiconductor equipment, cables need to bend and move frequently within limited space, placing extremely high demands on their flexibility and fatigue resistance. Traditional cables, due to material and design limitations, often perform poorly in these aspects, easily experiencing breakage, signal attenuation, and other problems, severely impacting the stable operation and lifespan of the equipment.

[0018] On the other hand, there is the application of ultra-flexible shielded cables in semiconductor equipment as described in any of the preceding claims.

[0019] The ultra-flexible shielded cable provided by this utility model has the following beneficial effects:

[0020] 1) The present invention provides an ultra-flexible shielded cable that ensures that it can effectively transmit large current and high frequency signals in high temperature environments. The ultra-high shielding rate can effectively block electromagnetic interference and ensure the stability of the transmitted signal. At the same time, it improves its flexibility, giving the cable good flexibility and fatigue resistance.

[0021] 2) The ultra-flexible shielded cable provided by this utility model, with a central cable core and a first cable core and a second cable core arranged sequentially from the inside to the outside, can ensure the stability of the internal structure of the cable and the layered transmission of signals.

The ultra-flexible shielded cable adopts a metal shielding layer (such as tinned copper wire braided shielding) and an insulating shielding layer (such as fluoroplastic copolymer insulating layer), which can effectively suppress electromagnetic interference inside the cable and isolate interference from external electromagnetic fields. This ensures that semiconductor equipment can transmit signals stably and accurately in complex electromagnetic environments, avoiding signal distortion and increased bit error rate. The high-quality conductor (such as compacted tinned copper wire conductor) and insulating layer (such as perfluoroethylene propylene copolymer insulating layer or ethylene-tetrafluoroethylene copolymer insulating layer) of the ultra-flexible shielded cable can maintain the clarity and strength of the signal, which enables the signal to maintain a high signal-to-noise ratio during transmission, improving the signal transmission quality and reliability.

Detailed Implementation

[0029] The preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, this utility model provides an ultra-flexible shielded cable, comprising: a cable core, the cable core including: a central cable core and a first cable core and a second cable core arranged sequentially from the inside to the outside of the central cable core, the first cable core including: a control signal line unit and a high-frequency communication signal line unit arranged alternately with the control signal line unit, the second cable core including: multiple control signal lines 1, the control signal line unit, the high-frequency communication signal line unit and the control signal line 1 each including: a compacted tinned copper wire conductor 8 and an insulation layer 9 of fluoroplastic copolymer disposed on the outside of the compacted tinned copper wire conductor 8, and a first tinned copper wire braided layer 3 disposed on the outside of the cable core.

[0031] This invention proposes an ultra-flexible shielded cable that ensures effective transmission of high current and high-frequency signals in high-temperature environments. The ultra-high shielding rate effectively blocks electromagnetic interference, ensuring the stability of transmitted signals. At the same time, it improves the flexibility, giving the cable good toughness and fatigue resistance, allowing it to bend and move frequently within the limited space of semiconductor equipment, greatly extending the cable's service life and meeting the stringent requirements of semiconductor equipment for cables.

[0032] Preferably, such as Figure 1 As shown, a Mylar layer 4 is provided between the cable core and the first tinned copper wire braided layer 3, and an outer sheath layer 5 is provided on the outside of the first tinned copper wire braided layer 3. The first tinned copper wire braided layer 3 includes: multiple first tinned copper wires, and the braiding pitch of the multiple first tinned copper wires is 110-120.

[0033] The Mylar layer 4 effectively isolates the electrical contact between the cable core and the first tinned copper wire braided layer 3, preventing current leakage or short circuits and thus ensuring the electrical safety of the cable. In high-temperature environments, the Mylar layer 4 maintains stable performance, preventing damage to the internal structure or performance degradation of the cable caused by temperature changes. The Mylar layer 4 also has a certain mechanical strength, providing support for the first tinned copper wire braided layer 3 and enhancing the overall structural stability of the cable. Furthermore, its thinness and flexibility facilitate cable installation and wiring.

[0034] The outer sheath layer 5 can prevent the cable from being corroded by the external environment, such as moisture, chemicals, ultraviolet rays, etc., thereby extending the service life of the cable; the outer sheath layer 5 can withstand a certain mechanical stress, preventing the cable from being damaged during bending, pulling, etc.; the outer sheath layer 5 also has fire-retardant properties, which can maintain the integrity of the cable in extreme situations such as fire and reduce the spread of fire.

[0035] The braiding pitch refers to the distance between two adjacent braided wires in the braided layer. In the first tinned copper wire braided layer 3, the braiding pitch of multiple first tinned copper wires is preferably 110-120 mm, or preferably 110, 115, or 120 mm. Due to space limitations and for the sake of brevity, this utility model will not exhaustively list the specific values ​​included in the range, so that the density of the first tinned copper wire braided layer 3 can reach more than 90%, which can provide a tighter shielding layer, reduce the impedance changes encountered by the signal during transmission, thereby reducing signal reflection and attenuation, and improving the shielding effect. Within this range, the first tinned copper wire braided layer 3 can effectively block the interference of external electromagnetic waves and ensure stable signal transmission. At the same time, an appropriate braiding pitch can improve the flexibility and toughness of the cable while ensuring the shielding effect. This allows the cable to bend and move frequently within the limited space of semiconductor equipment without affecting the bending performance of the cable due to the excessive stiffness of the braided layer.

[0036] Preferably, such as Figure 1 As shown, the central cable core includes: a central filler 6, and a control signal line 1 and multiple power lines 7 are arranged circumferentially on the outer side of the central filler 6. The control signal line 1 and the power lines 7 each include: a compacted tinned copper wire conductor 8 and an insulation layer 9 of fluoroplastic copolymer disposed on the outer side of the compacted tinned copper wire conductor 8.

[0037] Power line 7 transmits electrical energy from the power source (such as the power grid, generator, battery, etc.) to the electrical equipment to ensure the normal operation of the equipment. It is designed according to the power requirements of the equipment, can carry the corresponding current, avoid overheating or damage, reduce voltage loss during transmission, ensure that the equipment obtains a stable operating voltage, and ensure the stable operation of the power system.

[0038] Control signal line 1 plays a key role in signal transmission, low voltage / current transmission, precise control, anti-interference, multiplexing, long-distance transmission, electrical isolation, flexible wiring and system integration, ensuring the stable operation of the control system. It is responsible for transmitting control commands, such as switching, adjustment, start and stop signals, between equipment or systems, and transmitting low voltage and low current signals to ensure accurate transmission of control commands and achieve high-precision operation of equipment or systems.

[0039] The central filler 6 can fill the gaps inside the cable core, allowing the cable to maintain a round shape during manufacturing.

[0040] The compacted tin-plated copper wire conductor 8 includes: tin-plated copper wire and a tin-plated layer on the outside of the tin-plated copper wire. The tin-plated copper wire has good conductivity, which can ensure stable signal transmission and high current carrying capacity. The tin-plated layer can increase the mechanical strength and corrosion resistance of the copper wire, improve the durability of the cable, and the compacted design of the compacted tin-plated copper wire conductor can reduce the gaps between the tin-plated copper wire conductors, increase the conductor fill factor and current density, thereby increasing the current carrying capacity of the cable to ensure low resistance and high conductivity.

[0041] The fluoroplastic copolymer insulation layer 9 has excellent high temperature resistance and chemical corrosion resistance, and can maintain stable insulation performance in harsh environments. The fluoroplastic copolymer insulation layer 9 also has good electrical properties, which can reduce the decline in insulation performance caused by temperature changes or chemical corrosion. The fluoroplastic copolymer insulation layer 9 can protect the conductor from external environmental corrosion and mechanical damage, ensuring the safe operation of the cable.

[0042] Preferably, such as Figure 1 As shown, a second tinned copper wire braided layer 10 and an inner sheath 11 are sequentially provided from the inside to the outside of the control signal line 1 and the power line 7. The second tinned copper wire braided layer 10 includes: multiple second tinned copper wires, and the braiding pitch of the multiple second tinned copper wires is 25 to 28.

[0043] The second tinned copper wire braided layer 10 serves as a shielding layer, further enhancing the cable's shielding capability against external electromagnetic waves. Due to its excellent conductivity and braided structure, the tinned copper wire can form an effective electromagnetic shielding mesh, protecting the internal control signal line 1 and power line 7 from external electromagnetic interference. The second tinned copper wire braided layer 10 not only provides shielding but also increases the cable's mechanical strength, providing additional protection against damage under mechanical stresses such as bending and pulling.

[0044] In the second tinned copper wire braided layer 10, the braiding pitch of the multiple second tinned copper wires is preferably 25-28. The preferred braiding pitches are 25, 26, 27, or 28. Due to space limitations and for the sake of brevity, this utility model will not exhaustively list all the specific values ​​within this range. The choice of braiding pitch directly affects the shielding performance. Within this range, the braided layer can form a tight shielding mesh, allowing the density of the second tinned copper wire braided layer 10 to reach over 90%, reducing the possibility of electromagnetic wave penetration and thus improving the shielding effect. A smaller braiding pitch helps maintain the cable's flexibility; the copper wires in the braided layer are more tightly arranged together, reducing the overall stiffness of the cable and making it easier to bend and move.

[0045] The inner sheath 11 serves as the outer layer of protection for the second tinned copper wire braided layer 10. It can prevent the second tinned copper wire braided layer 10 from being damaged when the cable is bent or moved. It can also prevent external moisture, chemicals, etc. from penetrating into the cable and protect the overall structure of the cable from damage. The inner sheath is usually made of wear-resistant and corrosion-resistant materials, which can increase the durability of the cable. It can maintain the stable performance of the cable during long-term use and extend the service life of the cable.

[0046] Preferably, such as Figure 1 As shown, the control signal line unit consists of multiple control signal lines 1 and / or twisted control signal lines 12. The control signal line 1 includes: a compacted tin-plated copper wire conductor 8 and an insulating layer 9 of fluoroplastic copolymer disposed on the outside of the compacted tin-plated copper wire conductor 8.

[0047] The compacted tin-plated copper wire conductor 8 not only ensures efficient signal transmission, but also improves the mechanical strength and corrosion resistance of the conductor. At the same time, the compacted design of the compacted tin-plated copper wire conductor 8 reduces the gaps between conductors and improves the conductor fill factor, thereby increasing the current carrying capacity of the cable.

[0048] The fluoroplastic copolymer insulation layer 9 possesses excellent high-temperature resistance and chemical corrosion resistance, ensuring that it maintains stable insulation performance at high temperatures and preventing insulation degradation caused by temperature changes or chemical corrosion. The fluoroplastic copolymer insulation layer 9 also exhibits good electrical properties, such as high insulation resistance and low dielectric constant. This helps reduce signal attenuation and interference during transmission, improving signal transmission efficiency.

[0049] The fluoroplastic copolymer insulation layer 9 can tightly wrap around the outside of the compacted tin-plated copper wire conductor 8, preventing the compacted tin-plated copper wire conductor 8 from being damaged by external mechanical stress or chemicals. This helps to maintain the integrity and stability of the compacted tin-plated copper wire conductor 8 and ensure the normal operation of the cable.

[0050] When the control signal line unit includes twisted control signal lines 12, these twisted control signal lines 12 can further reduce mutual interference between signals. The twisted design makes the electromagnetic fields between two adjacent single-core wires 13 cancel each other out, thereby reducing crosstalk and noise between signals. This helps to improve the transmission quality and stability of signals, especially in high-frequency signal transmission or environments with strong electromagnetic interference.

[0051] Preferably, such as Figure 1As shown, the second cable core includes: multiple twisted control signal lines 12, each twisted control signal line 12 includes: multiple single-core wires 13, each single-core wire 13 includes: a compacted tinned copper wire conductor 8 and an insulation layer 9 of fluoroplastic copolymer disposed on the outside of the compacted tinned copper wire conductor 8, and each pair of single-core wires 13 are twisted together to form a twisted control signal line 12.

[0052] The compacted tin-plated copper wire conductor 8 not only ensures efficient signal transmission, but also improves the mechanical strength and corrosion resistance of the conductor. At the same time, the compacted design of the compacted tin-plated copper wire conductor 8 reduces the gaps between conductors and improves the conductor fill factor, thereby increasing the current carrying capacity of the cable.

[0053] The fluoroplastic copolymer insulation layer 9 is wrapped around the outside of the compacted tin-plated copper wire conductor 8 to prevent the compacted tin-plated copper wire conductor 8 from being damaged by external mechanical stress or chemical substances. At the same time, the fluoroplastic copolymer insulation layer 9 can maintain stable insulation performance in high temperature and harsh chemical environment. Moreover, the fluoroplastic copolymer insulation layer 9 has high insulation resistance and low dielectric constant, which helps to reduce attenuation and interference during signal transmission.

[0054] The twisted design causes the electromagnetic fields between two adjacent single-core wires 13 to cancel each other out, thereby reducing crosstalk and noise between signals. This design is particularly suitable for high-frequency signal transmission or environments with strong electromagnetic interference, and can significantly improve the transmission quality and stability of signals.

[0055] The twisted-pair design of the control signal lines 12 makes the cable more flexible when bending or moving, which helps to meet the stringent requirements of semiconductor devices for cables, especially in situations where frequent bending and movement are required in confined spaces; it also increases the mechanical strength of the cable, which enables the cable to better resist external stress and environmental effects during long-term use, thereby extending the cable's service life.

[0056] Preferably, such as Figure 1 As shown, the second cable core includes: filler 14, which fills between every two adjacent twisted control signal lines 12; the filler 14 can fill and support the gaps inside the cable, support the internal components, maintain the roundness and structural stability of the cable, prevent deformation, reduce mechanical stress damage to the internal conductors, enhance compressive and tensile strength, and fix the position of the internal twisted control signal lines, reduce signal interference, and improve transmission quality.

[0057] Preferably, such as Figure 1As shown, the high-frequency communication signal line unit is composed of multiple high-frequency communication signal lines 2. The high-frequency communication signal line 2 includes: a tightly pressed tinned copper wire conductor 8 and an insulating layer 9 of fluoroplastic copolymer disposed on the outside of the tightly pressed tinned copper wire conductor 8. An oblique sheath 15 and an inner sheath 11 are disposed sequentially from the inside to the outside of the insulating layer 9 of the fluoroplastic copolymer.

[0058] High-frequency communication signal line 2: Used for transmitting high-frequency signals (such as radio frequency, microwave, etc.), widely used in television, broadcasting, networks and wireless communication; its structure effectively reduces signal attenuation and ensures that the high-frequency signal maintains its strength during long-distance transmission; the outer shielding layer effectively blocks external electromagnetic interference, ensuring the stability and clarity of signal transmission; the coaxial high-frequency communication signal line has a robust structure, adapts to various environments, and provides long-term stable signal transmission.

[0059] The tin-plated copper wire in the compacted tin-plated copper wire conductor 8 has good conductivity, which can ensure stable signal transmission and high current passage. The tin plating layer can increase the mechanical strength and corrosion resistance of the tin-plated copper wire, improve the durability of the cable, and the compacted design of the compacted tin-plated copper wire conductor 8 can reduce the gap between conductors, increase the conductor fill factor and current density, thereby increasing the current carrying capacity of the cable to ensure low resistance and high conductivity.

[0060] The fluoroplastic copolymer insulation layer 9 has excellent high temperature resistance and chemical corrosion resistance, which ensures that the insulation layer can maintain stable insulation performance in high temperature environments and prevents the insulation performance from deteriorating due to temperature changes or chemical corrosion. The fluoroplastic copolymer insulation layer 9 also has good electrical properties, such as high insulation resistance and low dielectric constant, which helps to reduce signal attenuation and interference during transmission and improve signal transmission efficiency.

[0061] The slanted cladding 15 effectively blocks external electromagnetic interference, reduces signal attenuation and distortion, and improves signal transmission quality. The slanted cladding 15 provides mechanical protection, flexibility, grounding protection, reduces crosstalk, provides structural stability, and is suitable for high-frequency applications.

[0062] The inner sheath 11 provides electrical insulation to prevent short circuits or leakage between conductors, ensure stable current transmission, enhance the mechanical strength of the cable, resist external forces such as stretching, squeezing, and bending, prevent conductor damage, fix the position of the conductor, prevent it from moving or deforming, and maintain the stability of the cable structure.

[0063] Preferably, such as Figure 1 As shown, the insulating layer 9 of the fluoroplastic copolymer includes: a perfluoroethylene-propylene copolymer insulating layer or an ethylene-tetrafluoroethylene copolymer insulating layer, which ensures that it can effectively transmit large currents and high-frequency signals in high-temperature environments and protect the conductor from the influence of the external environment.
