The multi-core-in-one structure of the integrated cable, through scientific internal layout and isolation design, ensures that each signal is transmitted independently and does not interfere with each other while compressing the wiring space. This structure is not a simple bundling of multiple cables, but a systematic integration based on signal transmission characteristics, so that space utilization and transmission stability form a benign balance.
The layered twisting layout of the core wire is the basis for reducing space occupancy. The core wires with different functions are twisted together according to a certain rule to form a tight bundle structure. Compared with the separate wiring of a single cable, this integration can greatly reduce the gap between the cables and reduce the overall diameter. At the same time, the twisting angle and density are optimized so that each core wire can be evenly distributed inside the integrated cable, avoiding structural instability caused by local crowding, and realizing the orderly arrangement of multiple core wires in a limited space.
The isolation barrier between the core wires is the key to preventing interference. In the multi-core-in-one structure, each core wire or each group of core wires with similar functions is wrapped with an independent shielding layer. These shielding layers are usually composed of metal foil or metal mesh, which can effectively block the penetration of electromagnetic signals between the core wires. For core wires that transmit high-frequency signals, the density of the shielding layer will be higher to ensure that the electromagnetic radiation generated by it will not interfere with the adjacent low-frequency signal core wires, forming the effect of a "signal isolation cabin".
The design of a shared outer sheath further compresses the space. Multi-core wires are wrapped in the same layer of wear-resistant outer sheath, eliminating the outer sheath material of each single cable, which not only reduces the overall volume but also enhances the overall strength of the integrated cable. The insulating material filled inside the outer sheath fits each core wire tightly to prevent the core wires from rubbing against each other when bending or moving, causing damage to the shielding layer. At the same time, the insulating properties of the filling material can also help block signal interference and form an additional protective barrier.
Signal classification and integration reduces the possibility of cross-interference. The multi-core-in-one structure will centrally arrange the core wires that transmit the same type of signals. For example, the power core wire, data core wire, and control core wire are classified separately, and thicker isolation layers are set between core wires of different categories. Since the frequency and transmission characteristics of the same type of signals are similar, the mutual interference is small, and the physical isolation between categories can block the interference path of different types of signals, allowing each signal to maintain independent transmission in a compact space.
The symmetrical design of the structure balances the signal transmission environment. When twisting, the multi-core cables maintain a symmetrical geometric structure, so that the electromagnetic environment of each core is as consistent as possible, reducing the interference imbalance caused by position differences. This symmetry is particularly important when transmitting differential signals, which can ensure that the interference of positive and negative signals cancel each other out. Even in a crowded space with multiple cores, the integrity of the signal can be maintained to avoid signal distortion caused by structural asymmetry.
The flexible internal structure adapts to complex wiring environments. While maintaining a compact structure, the multi-core integrated cable still has good bending performance, which can adapt to multi-angle wiring in a small space and reduce the core misalignment or shielding layer damage caused by forced bending. This flexibility allows the integrated cable to be closely arranged along the contour of the equipment or pipeline, further saving wiring space. At the same time, the stable internal structure will not destroy the relative position of the core when bending, ensuring that the isolation barrier continues to work and signal interference is always within a controllable range.
In addition, the integrated design of the interface enhances the anti-interference ability of the terminal. The connector of the multi-core integrated cable adopts a modular design. The interfaces of different cores are arranged in order in the same connector. Each interface corresponds to an independent shielding component, forming a complete shielding system with the shielding layer inside the integrated cable. This end-to-end integrated design not only reduces the space occupied by the connector, but also avoids the signal cross-interference caused by the messy arrangement of the connectors of a single cable, so that the signal remains independent and stable throughout the entire process from transmission to connection.
Through multiple designs such as layout optimization, isolation protection, and classification integration, the multi-core integrated structure of the integrated cable successfully reduces the wiring space while ensuring the independent transmission and anti-interference ability of each signal, meeting the dual needs of complex electronic equipment for wiring efficiency and signal quality.
