Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing leaky coaxial cable may have ice attached to the leaky coaxial cable in the weather of low temperature, ice and snow, and winter rain, so that the leaky coaxial cable breaks or the support collapses, and it can only be passed through Manual deicing is time-consuming and laborious

Embodiment Construction

[0024] like figure 1 and 2 Shown are respectively a cross-sectional view and a schematic circuit structure diagram of a preferred embodiment of the leaky coaxial cable of the present invention. The leaky coaxial cable of the present invention includes an outer skin protection layer 101 , a shielding / leakage layer 102 , an insulating layer 103 and an inner wire 104 from outside to inside. The shielding / leakage layer 102 is provided with a leakage hole 106 for radiating wireless signals. In order to make the leaky coaxial cable generate heat, a heating wire 105 is arranged between the outer skin protection layer 101 and the shielding / leakage layer 102 . The heating wire 105 is pasted on the surface of the shielding / leakage layer 102 . In order to avoid affecting radio frequency parameters such as signal radiation, the heating wire 105 cannot cover the leakage hole 106 . Preferably, the heating wire 105 is arranged on the other side relative to the leakage hole 106 . The shie...

Abstract

The invention discloses a leaky coaxial cable and a system thereof. The leaky coaxial cable sequentially comprises an outer skin protecting layer, a shielding / leaky layer, an insulating layer and an inside conductor from outside to inside. A leaky hole is formed in the shielding / leaky layer, and a heating conductor is arranged between the outer skin protecting layer and the shielding / leaky layer. The invention further discloses a system of the leaky coaxial cable. The system comprises at least a plurality of sections of leaky coaxial cables which are connected end to end through first connectors and second connectors, each leaky coaxial cable sequentially comprises the outer skin protecting layer, the shielding / leaky layer, the insulating layer and the inside conductor from outside to inside, the leaky hole is formed in each shielding / leaky layer, and the heating conductor is arranged between each outer skin protecting layer and each shielding / leaky layer. According to the leaky coaxial cable and the system thereof, a self-heating function is started as required to enable ice and snow covering the leaky cables to melt timely and fall off naturally, so that large silver thaw can be avoided, and the problems due to manual deicing operations are solved.

Description

technical field [0001] The invention relates to the field of cables, in particular to a leaky coaxial cable and a system thereof. Background technique [0002] Leaky coaxial cables are mainly used in weak field areas to provide services for wireless signal coverage and play the role of antennas. In continuous tunnels, it is also possible to use leaky coaxial cables directly through the open space, with hanging rods between tunnels. In winter, due to the influence of ice, snow and winter rain, ice will accumulate on the leaky cable. Excessive ice load will cause a huge burden on the load-bearing of the leaky cable and may cause the leaky cable or support to break, thereby affecting the wireless signal coverage effect. And bring safety hazard to driving. In winter, due to the influence of low temperature, ice, snow and winter rain, ice may be attached to the leaky cable. As the severe weather continues, the ice load of the leaky cable will increase, which may eventually lead...
