Description

Technical Field

[0001] The invention relates to the technical field of cable structures, in particular to a flexible intelligent soft cable for communication power supply. Background Art

[0002] The existing power cables for communication equipment such as large data centers and base stations have a relatively thick metal body, which makes the entire cable relatively hard. As a result, a larger turning radius needs to be set at the bends when laying the cables. For small areas, the laying of such cables is difficult. In addition, in actual use, it is impossible to know whether the existing cables are overloaded, resulting in excessive local temperature, which can cause the entire cable to age prematurely due to overload or the outer sheath to burn out, leading to accidents such as short circuits. Summary of the invention

[0003] In response to the above problems, the present invention provides a flexible intelligent soft cable for communication power supply, which makes the cable soft and convenient for bending and laying in a narrow area; and the cable has a built-in temperature sensing module. When the local temperature is too high, human intervention is performed to reduce the aging degree of the cable and ensure reliable and safe operation of the cable.

[0004] A flexible intelligent soft cable for communication power supply, characterized in that it comprises:

[0005] The cable core part includes a plurality of multi-core wire twisted areas at the center, a filling rope, and a plurality of temperature sensing modules arranged at intervals. Each of the multi-core wires includes a central conductor part and an outer insulating layer. The central conductor part is composed of a plurality of single wires. The outer insulating layer is made of a flexible material. Each single wire is an extremely fine tinned single wire.

[0006] The reinforcement layer includes a non-woven fabric covering layer and an aluminum-plastic composite tape arranged radially from the inside to the outside;

[0007] and an outer sheath;

[0008] The outer circumference of the cable core part is wrapped with the reinforcement layer part, and the outer circumference of the reinforcement layer part is covered with the outer protective layer;

[0009] Several temperature sensing modules are arranged at intervals along the length direction of the cable, and the temperature sensing parts of each group of temperature sensing modules are arranged in contact with the outer insulation layer of the multi-core wire at the corresponding position. Each group of temperature sensing modules uploads temperature information to the external temperature detection module in real time through communication.

[0010] It is further characterized by:

[0011] The adjacent temperature sensing modules are connected by optical fibers, which are externally connected to an external temperature detection module. The external temperature detection module provides low voltage for all temperature sensing modules on the cable at the same time, so that the external temperature detection module can reliably monitor the temperature of the cable in the corresponding length area.

[0012] The number of the multi-core wires is three, and the three multi-core wires with the same wire diameter are twisted at a pitch of 40 times the pitch diameter ratio;

[0013] The diameter of the single wire in each multi-core wire is 0.03mm-0.08mm, and the elongation at break of the single wire is controlled at 16%-20%, which makes the central conductor part formed by the combination of the single wires soft, with a small bending radius, and not easy to break;

[0014] The outer insulating layer includes a first insulating layer and a second insulating layer from the inside to the outside, the first insulating layer is made of ethylene propylene rubber, and the second insulating layer is made of super flexible polyvinyl chloride insulating material;

[0015] The non-woven fabric covering layer is a single-layer wrapping structure with an overlap rate of 10% to 20% and a coverage rate of 100%;

[0016] The aluminum foil layer of the aluminum-plastic composite tape is arranged inwardly and the plastic film is arranged outwardly. The aluminum-plastic composite tape is a wrapping structure with a single layer, an overlap rate of 5% to 10%, and a covering rate of 100%.

[0017] The outer sheath is made of -40°C ultra-soft polyvinyl chloride sheath material.

[0018] After adopting the structure of the present invention, since the central conductor part of each multi-core wire is formed by a combination of several extremely fine tinned monofilaments, the central conductor part forming a whole under the same cross-sectional area is relatively soft, which makes the cable soft and convenient for bending and laying in a narrow area; and the cable has a built-in temperature sensing module. When the local temperature is too high, human intervention is performed to reduce the aging degree of the cable and ensure reliable and safe operation of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] A flexible intelligent soft cable for communication power supply, see Figure 1-Figure 2 , which includes a cable core part 10, a reinforcement layer part 20, and an outer sheath 30;

[0024] The cable core part 10 includes a plurality of multi-core wire twisted areas 40 at the center, a filling rope 50, and a plurality of temperature sensing modules 60 arranged at intervals. Each multi-core wire 70 includes a central conductor part and an outer insulating layer. The central conductor part is composed of a plurality of monofilaments 71. The outer insulating layer is made of a flexible material, and each monofilament is an extremely fine tinned monofilament. The diameter of the monofilament 71 in each multi-core wire is 0.03 mm to 0.08 mm, and the elongation at break of the monofilament 71 is controlled at 16% to 20%, which makes the central conductor part formed by the combination of the monofilaments 71 soft, with a small bending radius, and not easy to break. The outer insulating layer includes a first insulating layer 72 and a second insulating layer 73 from the inside to the outside. The material of the first insulating layer 72 is ethylene propylene rubber, and the material of the second insulating layer 73 is super-flexible polyvinyl chloride insulating material.

[0025] The reinforcement layer 20 includes a non-woven fabric covering layer 21 and an aluminum-plastic composite tape 22 which are radially arranged from the inside to the outside. In a specific embodiment, the non-woven fabric covering layer 21 is a wrapping structure with a single layer, an overlap rate of 10% to 20%, and a coverage rate of 100%. The aluminum foil layer of the aluminum-plastic composite tape 22 is arranged inwardly and the plastic film is arranged outwardly. The aluminum-plastic composite tape is a wrapping structure with a single layer, an overlap rate of 5% to 10%, and a coverage rate of 100%.

[0026] The outer circumference of the cable core part 10 is wrapped with a reinforcement layer part 20 , and the outer circumference of the reinforcement layer part 20 is covered with an outer sheath 30 .

[0027] In a specific embodiment, the number of the multi-core wires 70 is three, and the three multi-core wires 70 with the same wire diameter are twisted at a pitch of 40 times the pitch diameter ratio; the colors of the second insulation layers 73 of the three multi-core wires are different from each other, so that subsequent identification is convenient;

[0028] Several temperature sensing modules 60 are arranged at intervals of 5 meters to 20 meters along the length direction of the cable. In specific implementation, the temperature sensing modules 60 are arranged at intervals of 10 meters along the length direction of the cable. The temperature sensing part of each group of temperature sensing modules 60 is arranged in contact with the second insulation layer 73 of the multi-core wire 70 at the corresponding position. Adjacent temperature sensing modules 70 are connected by optical fibers 80, and the optical fibers 80 are externally connected to an external temperature detection module 90. The external temperature detection module 90 simultaneously provides low voltage for all temperature sensing modules 70 on the cable, so that the external temperature detection module 90 can reliably monitor the temperature of the cable in the corresponding length area.

[0029] In a specific embodiment, the outer sheath is made of -40°C ultra-flexible polyvinyl chloride sheath material.

[0030] Since the central conductor part of each multi-core wire is formed by a combination of several extremely fine tinned monofilaments, the central conductor part that forms the whole under the same cross-sectional area is relatively soft, which makes the cable soft and convenient for bending and laying in a small area. It can meet the arbitrary use of both AC and DC power supply systems and can perfectly solve the problem of bending radius of cable laying in a small area in the computer room; and the cable has a built-in temperature sensing module, and each group of temperature sensing modules is provided with a corresponding electronic number. The temperature sensing module transmits the electronic number of the chip and the corresponding temperature to the external temperature detection module in real time. When the local temperature is too high, human intervention is performed to reduce the temperature of the cable at the corresponding position, thereby reducing the aging degree of the cable and ensuring reliable and safe operation of the cable.
