Abstract

The invention provides a leakage coaxial cable, comprising an inner conductor, an insulation layer, an outer conductor and a sheathing layer which are sequentially arranged from inside to outside; wherein the outer conductor is provided with a notch, the outer conductor is a metal composite layer provided with self-adhesion structure and is bonded with the insulation layer into a whole. The invention also provides a manufacturing method of the leakage coaxial cable, including that: a metal foil provided with self-adhesion structure is longitudinally wrapped onto the insulation layer; the sheathing layer is subject to extrusion moulding; and cooling is carried out in a cooling water tank. The leakage coaxial cable of the invention has high structural stability and good bending property; besides, the metal foil provided with self-adhesion structure is adopted, metal dosage is reduced, metal strip embossing or coining and lapping after longitudinal wrapping in the existing process are eliminated, production efficiency is improved, and production cost is reduced.

Description

technical field

[0001] The invention relates to a coaxial cable and a manufacturing method thereof, in particular to a leaky coaxial cable and a manufacturing method thereof. Background technique

[0002] Leaky coaxial cables radiate and receive electromagnetic wave signals outward by setting openings on the outer conductors, so they have dual functions of signal transmission lines and transceiver antennas, and are mainly used in occasions where wireless signal propagation is poor, such as tunnels, subways, underground buildings, mountainous areas, etc. environment. In the prior art, the spacing and shape of the outer conductor openings are usually optimized to reduce the variation of coupling loss and transmission loss of the leaky coaxial cable.

[0003] figure 1 It is a schematic diagram after the end of a leakage coaxial cable of the prior art is cut open, such as figure 1 As shown, the leaky coaxial cable includes an inner conductor 10 , an insulating layer 20 , an o...
