Description

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

[0003] Traditional shielded cables usually adopt ordinary copper conductors and conventional insulating 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 posing safety hazards. At the same time, the shielding layers of these cables mostly use copper meshes or copper foils. Although they can provide a certain shielding effect, when facing high-frequency electromagnetic wave interference, the shielding efficiency is limited, making it difficult to ensure the stable transmission of signals.

[0004] In addition, as the space of semiconductor devices becomes increasingly compact, cables need to be frequently bent and moved within a limited space, which poses extremely high requirements for the flexibility and fatigue resistance of the cables. Due to material and design limitations, traditional cables often perform poorly in these aspects, easily experiencing problems such as breakage and signal attenuation, seriously affecting the stable operation and service life of the devices.

Detailed Embodiments

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] As Figure 1 shown, the present invention provides a super-flexible shielded cable, comprising: a cable core, the cable core comprising: a central cable core and a first cable core and a second cable core sequentially arranged from inside to outside on the outside of the central cable core, the first cable core comprising: a control signal line unit and a high-frequency communication signal line unit alternately arranged with the control signal line unit, the second cable core comprising: a plurality of control signal lines 1, the control signal line unit, the high-frequency communication signal line unit and the control signal line 1 all comprising: a tightly compressed tinned copper wire conductor 8 and an insulating layer 9 of a fluoroplastic copolymer arranged on the outside of the tightly compressed tinned copper wire conductor 8, and a first tinned copper wire braided layer 3 is arranged on the outside of the cable core.

[0031] The present invention proposes a super-flexible shielded cable and its application, ensuring that it can effectively transmit large currents and high-frequency signals in a high-temperature environment, and the ultra-high shielding rate can effectively block the interference of electromagnetic waves, ensuring the stability of the transmitted signal. At the same time, its softness is improved, enabling the cable to have good flexibility and fatigue resistance, and it can be frequently bent and moved within the limited space of semiconductor equipment, greatly extending the service life of the cable to meet the stringent requirements of semiconductor equipment for cables.

[0032] Preferably, as Figure 1 shown, a mylar layer 4 is further arranged between the cable core and the first tinned copper wire braided layer 3, and an outer sheath layer 5 is further arranged on the outside of the first tinned copper wire braided layer 3. The first tinned copper wire braided layer 3 comprises: a plurality of first tinned copper wires, and the braiding pitch of the plurality of first tinned copper wires is 110 - 120;

[0033] The mylar layer 4 can effectively isolate the electrical contact between the cable core and the first tinned copper wire braided layer 3, preventing current leakage or short-circuit phenomena from occurring, thereby ensuring the electrical safety of the cable; in a high-temperature environment, the mylar layer 4 can maintain stable performance, preventing the damage or performance degradation of the internal structure of the cable caused by temperature changes; the mylar layer 4 also has a certain mechanical strength, which can provide support for the first tinned copper wire braided layer 3, enhancing the overall structural stability of the cable, and it is thin, flexible, and convenient for the installation and wiring of the cable;

[0034] The outer sheath layer 5 can prevent the cable from being eroded by the external environment, such as moisture, chemical substances, 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 the performance of fire prevention and flame retardancy, and can maintain the integrity of the cable in extreme situations such as fires, reducing the spread of fires.

[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 said first tinned copper wires is preferably 110 - 120, and the braiding pitch of multiple said first tinned copper wires is preferably 110, 115 or 120. Due to space limitations and for the sake of brevity, the present invention does not exhaustively list the specific point values included in the said range, enabling the density of the first tinned copper wire braided layer 3 to reach over 90%, capable of providing a denser shielding layer, reducing impedance changes encountered by the signal during transmission, thereby reducing signal reflection and attenuation, improving the shielding effect. Within this range, the first tinned copper wire braided layer 3 can effectively block external electromagnetic wave interference and ensure stable signal transmission; at the same time, an appropriate braiding pitch can improve the softness and flexibility of the cable while ensuring the shielding effect, enabling the cable to bend and move frequently within the limited space of semiconductor devices without affecting the bending performance of the cable due to the excessive hardness of the braided layer.

[0036] Preferably, as Figure 1 shown, the central cable core includes: a central filler 6, with a control signal wire 1 and multiple power wires 7 circumferentially arranged on the outer side of the central filler 6. Both the control signal wire 1 and the power wire 7 include: a tightly pressed tinned copper wire conductor 8 and an insulating layer 9 of fluoroplastic copolymer provided on the outer side of the tightly pressed tinned copper wire conductor 8;

[0037] The power wire 7 transmits electrical energy from a power source end (such as a power grid, a generator, a battery, etc.) to an electrical device, ensuring the normal operation of the device. It is designed according to the power demand of the device, capable of carrying the corresponding current, avoiding overheating or damage, reducing voltage loss during transmission, ensuring that the device obtains a stable working voltage, and ensuring the stable operation of the power system;

[0038] The control signal wire 1 plays a key role in aspects such as signal transmission, low - voltage / current transmission, precise control, anti - interference, multi - path transmission, long - distance transmission, electrical isolation, flexible wiring, and system integration, ensuring the stable operation of the control system. It is responsible for transmitting control instructions between devices or systems, such as signals for switching, adjusting, starting, stopping, etc., transmitting low - voltage, low - current signals, ensuring the accurate transmission of control instructions, and realizing high - precision operation of the device or system;

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

[0040] The compacted tinned copper wire conductor 8 includes: tinned copper wire and a tinned layer on the outer side of the tinned copper wire. The tinned copper wire has good electrical conductivity, which can ensure the stable transmission of signals and the passage of large currents; the tinned layer can increase the mechanical strength and corrosion resistance of the copper wire, improving the durability of the cable. The compacted design of the compacted tinned copper wire conductor can reduce the gaps between the tinned copper wire conductors, improve the filling factor and current density of the conductor, thereby increasing the current-carrying capacity of the cable to ensure low resistance and high electrical conductivity;

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

[0042] Preferably, as Figure 1 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: a plurality of second tinned copper wires, and the braiding pitch of the plurality of second tinned copper wires is 25-28;

[0043] The second tinned copper wire braided layer 10 serves as a shielding layer, which can further enhance the shielding ability of the cable against external electromagnetic waves. Due to its good electrical conductivity and braiding structure, the tinned copper wire can form an effective electromagnetic shielding network to protect 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 a shielding function, but also increases the mechanical strength of the cable. It can provide additional protection for the cable to prevent damage under mechanical stresses such as bending and pulling.

[0044] In the second tinned copper wire braided layer 10, the braiding pitch of the plurality of second tinned copper wires is preferably 25-28. The braiding pitch of the plurality of second tinned copper wires is preferably 25, 26, 27 or 28. Limited by space and for the sake of simplicity, the present invention does not exhaustively list the specific point values included in the range. The choice of the braiding pitch has a direct impact on the shielding performance. Within this range, the braided layer can form a tight shielding network, making the density of the second tinned copper wire braided layer 10 reach more than 90%, reducing the possibility of electromagnetic wave penetration, thereby improving the shielding effect; a smaller braiding pitch helps to maintain the flexibility of the cable. The copper wires in the braided layer are arranged more closely together, reducing the overall stiffness of the cable and making the cable easier to bend and move;

[0045] The inner sheath 11 serves as the outer protection of the second tinned copper wire braided layer 10, which can prevent the second tinned copper wire braided layer 10 from being damaged when the cable bends or moves. It can also prevent external moisture, chemicals, etc. from invading the cable interior and protect the overall structure of the cable from being damaged. 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, as Figure 1 shown, the control signal line unit is composed of multiple control signal lines 1 and / or twisted control signal lines 12. The control signal line 1 includes: a compacted tinned copper wire conductor 8 and an insulating layer 9 of fluoroplastic copolymer disposed outside the compacted tinned copper wire conductor 8;

[0047] The compacted tinned copper wire conductor 8 can not only ensure the efficient transmission of signals, but also improve the mechanical strength and corrosion resistance of the conductor. At the same time, the compacted design of the compacted tinned copper wire conductor 8 reduces the voids between the conductors, improves the filling factor of the conductor, and thus increases the current-carrying capacity of the cable;

[0048] The fluoroplastic copolymer insulating layer 9 has excellent high-temperature resistance and chemical corrosion resistance, which ensures that the fluoroplastic copolymer insulating layer 9 can maintain stable insulation performance in a high-temperature environment and prevent the insulation performance from decreasing due to temperature changes or chemical substance erosion. The fluoroplastic copolymer insulating layer 9 also has good electrical properties, such as high insulation resistance, low dielectric constant, etc. This helps to reduce signal attenuation and interference during transmission and improve signal transmission efficiency;

[0049] The fluoroplastic copolymer insulating layer 9 can closely wrap around the outside of the compacted tinned copper wire conductor 8 to prevent the compacted tinned copper wire conductor 8 from being damaged by external mechanical stress or chemical substances, which helps to maintain the integrity and stability of the compacted tinned 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 the mutual interference between signals. The twisting design makes the electromagnetic fields between adjacent single-core wires 13 cancel each other out, thereby reducing signal crosstalk and noise, which helps to improve signal transmission quality and stability, especially in environments with high-frequency signal transmission or strong electromagnetic interference.

[0051] Preferably, as Figure 1As shown, the second cable core includes: a plurality of twisted control signal lines 12, and the twisted control signal lines 12 include: a plurality of single-core wires 13, and the single-core wires 13 include: a compacted tinned copper wire conductor 8 and an insulating layer 9 of fluoroplastic copolymer disposed outside the compacted tinned copper wire conductor 8. Every two single-core wires 13 are twisted to form a twisted control signal line 12;

[0052] The compacted tinned copper wire conductor 8 can not only ensure the efficient transmission of signals, but also improve the mechanical strength and corrosion resistance of the conductor. At the same time, the compacted design of the compacted tinned copper wire conductor 8 reduces the gaps between the conductors, improves the filling factor of the conductor, and thus increases the current-carrying capacity of the cable;

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

[0054] The twisted design enables 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 control signal line 12 with the twisted design makes the cable more flexible when bent or moved, which helps to meet the stringent requirements of semiconductor equipment for cables, especially in cases where frequent bending and movement are required in a limited space; it also increases the mechanical strength of the cable, which enables the cable to better resist external stress and environmental impacts during long-term use, thereby extending the service life of the cable.

[0056] Preferably, as Figure 1 shown, the second cable core includes: a filler 14, and the filler 14 is filled between every two adjacent twisted control signal lines 12; the filler 14 can fill and support the voids inside the cable to support the internal components, maintain the roundness and structural stability of the cable, prevent deformation, reduce damage to the internal conductors caused by mechanical stress, enhance the compressive and tensile capabilities, and at the same time fix the positions of the internal twisted control signal lines, reduce signal interference, and improve the transmission quality.

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

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

[0059] The tinned copper wire in the tightly pressed tinned copper wire conductor 8 has good electrical conductivity, which can ensure the stable transmission of signals and the passage of large currents; the tinned layer can increase the mechanical strength and corrosion resistance of the tinned copper wire, improve the durability of the cable. The tightly pressed design of the tightly pressed tinned copper wire conductor 8 can reduce the voids between conductors, improve the filling factor and current density of the conductor, thereby increasing the current-carrying capacity of the cable to ensure low resistance and high electrical conductivity;

[0060] The fluoroplastic copolymer insulating layer 9 has excellent high-temperature resistance and chemical corrosion resistance, which ensures that the insulating layer can maintain stable insulating performance in high-temperature environments and prevent the decline of insulating performance caused by temperature changes or chemical substance erosion; the fluoroplastic copolymer insulating layer 9 also has good electrical properties, such as high insulation resistance, low dielectric constant, etc., which helps to reduce signal attenuation and interference during transmission and improve signal transmission efficiency;

[0061] The inclined wrapping layer 15 effectively blocks external electromagnetic interference, reduces signal attenuation and distortion, and improves signal transmission quality. The inclined wrapping layer 15 has functions in mechanical protection, flexibility, grounding protection, reducing crosstalk, structural stability, and adapting to high-frequency applications;

[0062] The inner sheath 11 provides electrical insulation, prevents short circuits or leakage between conductors, ensures the stable transmission of current, enhances the mechanical strength of the cable, resists external forces such as stretching, extrusion, and bending, prevents the conductors from being damaged, fixes the positions of the conductors, prevents them from moving or deforming, and maintains the stability of the cable structure.
