Abstract
Description
Technical Field
[0001] This utility model belongs to the field of DC multi-core cables, specifically, it relates to a DC multi-core cable for high-mast lighting with network communication capabilities. Background Technology
[0002] A DC multicore cable is a cable specifically designed to transmit direct current. It typically contains multiple conductors (cores), each of which can independently transmit current.
[0003] Using DC multicore cables in high-mast lighting offers several advantages, especially in modern urban lighting and intelligent lighting systems. The application of DC multicore cables is becoming increasingly common. The multicore structure supports the simultaneous transmission of power and control signals. At the same time, DC power has relatively low energy loss during transmission, which can significantly improve the energy efficiency of the light source. Multicore cables can transmit power and control signals simultaneously, reducing the complexity of wiring and lowering construction costs.
[0004] However, for DC multi-core cables that require network communication, simply adding a communication core can increase the communication function. But to ensure the effectiveness and stability of power transmission and data transmission, it is necessary not only to arrange the internal cores, but also to ensure that each communication core has good shielding to reduce external electromagnetic interference. Utility Model Content
[0005] To address the above deficiencies, this utility model provides a DC multi-core cable for high-mast lighting with network communication capabilities, comprising a power core wire, a ground wire, and a communication core wire. Several of the power core wires, ground wires, and communication core wires are located inside a shielding layer, and a protective layer is provided on the outside of the shielding layer.
[0006] The shielding layer is divided into independent cavities by several arc-shaped insulating partitions separating the internal power and communication core wires.
[0007] Several insulating partitions are separated by insulating tape;
[0008] A central filling core is provided at the center of several insulating partitions;
[0009] The shielding layer is filled with polyethylene filler.
[0010] Furthermore, the insulating partition is formed by splicing two S-shaped insulating boards, and the end closest to the central filling core is the splicing end, the radius of the splicing end is smaller than the radius of the non-splicing end.
[0011] Furthermore, the insulating strip is fixed to the adjacent insulating partitions on both sides.
[0012] Furthermore, the communication core wire is a twisted pair structure.
[0013] Furthermore, the ground wire is in contact with the shielding layer.
[0014] Compared with the prior art, the present invention has the following advantages:
[0015] Compared to traditional DC multi-core cables, it not only has the traditional function of simultaneously transmitting power and control signals, but also has the function of communication.
[0016] By avoiding cross-wiring and close-range wiring through a reasonable wiring layout, the risk of interference is reduced. With effective shielding, it can achieve safe and stable transmission of power and data, meeting the needs of smart lighting and other applications. Attached Figure Description

Embodiments of the device are shown in the drawings. However, this device can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.
[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] Example
[0022] like Figure 1 As shown, this embodiment provides a DC multi-core cable for high-mast lights with network communication, including a power core wire 3, a ground wire 4 and a communication core wire 2. Several power core wires 3, ground wires 4 and communication core wires 2 are located inside the shielding layer 7. The shielding layer 7 is covered with a protective layer 8 for external protection, and the ground wire 4 is in contact with the shielding layer 7.
[0023] The shielding layer 7 is separated into independent cavities by several arc-shaped insulating partitions 6, which ensure that the independently stored communication core wire 2 is not affected by external electromagnetic interference, thus ensuring the effectiveness and stability of data transmission.
[0024] The insulating partition 6 is made of two S-shaped insulating boards spliced together, and the end closest to the central filling core 1 is the splicing end. The radius of the splicing end is smaller than the radius of the non-splicing end.
[0025] Several insulating partitions 6 are separated by insulating strips 5, and the insulating strips 5 are fixed to the adjacent insulating partitions 6 on both sides. The purpose is to allow each insulating partition 6 to form an independent area for placing the power core wire 3. At the same time, the S-shaped shape can deform and spring back when the cable is squeezed.
[0026] A central filling core 1 is provided at the center of several insulating partitions 6;
[0027] The interior of shielding layer 7 is filled with polyethylene filler;
[0028] Communication core 2 is a twisted pair structure.
[0029] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
