Problems solved by technology

However, this structure also has some shortcomings in actual use; firstly, the outer conductor of the smooth metal tube cannot be well bonded to the outer sheath and the insulating core layer, and it is easy to produce relative slippage, resulting in relatively poor bending performance, which is harmful to the cable. The installation performance, mechanical performance and service performance of the cable have a very adverse effect; in addition, the waterproof and corrosion resistance of this cable is also poor, and it cannot prev...

Abstract

The invention discloses a high-performance radiant leaky coaxial cable which comprises an inner conductor, an insulating layer, an outer conductor and an outer jacket, wherein the inner conductor is embedded in the outer conductor through the insulating layer, and the inner conductor and the outer conductor are positioned at the position of a concentric circle; the outer conductor is provided witha plurality of rabbets along the longitudinal direction; the insulating layer sequentially comprises an inner insulating surface layer, an insulating foaming layer and an outer insulating surface layer from the inside out; and a bonding layer which is a natural adhesive coating or a synthetic adhesive coating is arranged between the outer conductor and the outer jacket. The coaxial cable not onlyhas excellent bending mechanical property and waterproof and anti-corrosion property, but also has excellent information transmission performance. Meanwhile, the coaxial cable also has the characteristics of simple structure and convenient mounting and construction.

Description

technical field [0001] The invention relates to a signal transmission cable in the technical field of wireless communication, in particular to an improvement of a radiation-type leaky coaxial cable insulation structure. Background technique [0002] Leaky coaxial cable is an open transmission cable used for radio communication signal transmission. The signal is transmitted along the interior of the cable, and part of it is coupled to the transmission system formed by the conductor and the surrounding environment through the pores on the outer conductor. When the leaky coaxial cable communicates, it can generate a uniform signal field strength within a certain range without being affected by the surrounding environment. The communication reliability is high, and there is no communication blind area. The receiving level is stable and it is not easy to be interfered by external signals. . Therefore, the coaxial cable has the advantages of improving radio wave coverage and effe...
