Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator cable technology, and in particular to a flat multi-core elevator cable containing a network cable. Background Technology
[0002] Traditional elevator cables typically only perform power transmission. However, with the development of intelligent and digital elevator technologies, the demand for data communication between the elevator car and the control system is increasing. Traditional solutions often require the installation of separate network cables, leading to complex wiring, increased costs, and electromagnetic interference from multiple parallel cables, affecting signal transmission stability. Furthermore, the structural design of traditional elevator cables is insufficient in terms of tensile strength, bending resistance, and space utilization, making it difficult to meet the mechanical stress requirements of elevators during long-term operation. Additionally, the disordered arrangement of the internal conductors affects insulation performance and signal transmission quality. Utility Model Content
[0003] To address some of the problems existing in the prior art, this utility model provides a flat multi-core elevator cable with integrated network cable. Through the design of integrated network cable, reinforcing core and shielding layer, this cable achieves multiple optimizations in power transmission, data communication, mechanical strength and anti-interference ability, thereby improving the practicality and functionality of the cable.
[0004] To achieve the above objectives, this utility model provides a flat multi-core elevator cable with a network cable, comprising a cable body, the cable body including an outer sheath, the outer sheath being generally flat; a first reinforcing core and a second reinforcing core are symmetrically arranged at intervals inside the outer sheath, and a second conductive wire, a third conductive wire, a network cable, and multiple shielding wires are arranged between the first reinforcing core and the second reinforcing core; the shielding wire includes multiple insulated wire cores, and a shielding layer is wound around the outside of the insulated wire cores; multiple first conductive wires are also symmetrically arranged at both ends inside the outer sheath.
[0005] In operation, the outer sheath serves as the outermost protective structure, effectively preventing the cable from suffering physical damage and chemical corrosion from the external environment, providing a stable working environment for the internal components. The first and second reinforcing cores enhance the cable's mechanical strength and stability, withstanding mechanical stresses such as tension and bending forces that the cable may experience. The first, second, and third conductive wires are responsible for transmitting current, carrying different magnitudes or directions of current according to circuit requirements, completing the task of power distribution and transmission. The insulation layer of their conductive cores uses J-70 PVC insulation material to prevent current leakage and short circuits. The shielding layer in the shielding wire effectively reduces electromagnetic interference and radio frequency interference. To prevent interference and protect the internal conductors from external electromagnetic fields, the shielding layer is made of 0.10mm tinned soft copper wire cross-braided, with polyester tape wrapped inside the shielding layer; the insulated conductors are made of HDPE insulation material, providing electrical insulation to ensure that current can only be transmitted through the conductive wires, maintaining the stability and safety of the circuit; the network cable serves as a data transmission channel, connecting control equipment, sensors, or other data terminals to transmit digital or analog signals, enabling communication and data exchange between the elevator control system and external equipment; PP filler rope fills the gaps between the conductive conductors in the first conductive wire, maintaining the roundness of the first conductive wire and the stability of its internal structure.
[0006] The beneficial effects of this utility model are as follows: By symmetrically arranging a left-handed twisted first reinforcing core and a right-handed twisted second reinforcing core inside the flat outer sheath, a mechanically balanced structure against torsional stress is formed, significantly enhancing the tensile strength and bending resistance of the cable during elevator operation and effectively extending the cable's service life; placing the CAT.5e network cable at the center of the cable body and arranging it parallel to the reinforcing core avoids additional wiring, achieving synchronous transmission of power and data and simplifying the elevator system wiring structure; the shielding wire uses insulated cores twisted together with a shielding layer braided from tinned soft copper wire and polyester tape wrapping, effectively reducing electromagnetic interference and ensuring the stability of data transmission; the first conductive wire is filled with PP filler rope, making the cable structure more rounded and compactly arranged; the flat outer sheath design not only saves installation space but also facilitates cable laying in the elevator shaft; the application of the reinforcing core significantly enhances the cable's mechanical strength, enabling it to adapt to the environment of frequent elevator movement and bending, improving the cable's stability and durability.
[0007] As a further improvement of this utility model, in order to reduce magnetic field interference by utilizing adjacent conductors with opposite twisting directions, and to optimize different current transmission paths to improve the conductivity, stability, and adaptability of the cable; multiple first conductive wires are arranged side by side, and each of the first, second, and third conductive wires contains a conductive conductor; the nominal cross-section of the conductive conductor in the first conductive wire is 0.75mm², and the conductive conductors are twisted together, with the conductive conductors in adjacent first conductive wires having opposite twisting directions; the nominal cross-sections of the conductive conductors in the second and third conductive wires are 0.75mm² and 1.5mm², respectively; the first, second, and third conductive wires are also provided with a conductive conductor insulation layer, which is J-70 PVC insulation material.

[0009] As a further improvement of this utility model, in order to fill the gaps after the core strands are twisted, make the cable structure more compact, avoid core displacement due to vibration during operation, and improve the stability of the cable structure, PP filler rope is filled in the gaps between the conductive cores in the first conductive wire, and the diameter of the PP filler rope is 0.5mm.
[0010] As a further improvement of this utility model, in order to reduce the bending deformation of the network cable by utilizing the mechanical support of the reinforcing core and ensure the stability of data transmission, the network cable is a CAT.5e network cable, and the network cable is located at the center of the cable body; the network cable and the first reinforcing core and the second reinforcing core are arranged parallel to each other along the axial direction of the cable body.
[0011] As a further improvement of this utility model, in order to form torque balance by reversing the twisting directions, enhance the cable's anti-torsion ability, and adapt to the frequent bending conditions during elevator operation, both the first reinforcing core and the second reinforcing core are made of soft steel rope, and the twisting directions of the first reinforcing core and the second reinforcing core are left and right, respectively.
