Embodiment Construction

[0007] As shown in Figure 1 and Figure 2, the multi-core coaxial cable includes a jacket 1, and the center of the jacket is provided with a plurality of signal cables 3 wrapped by a central sheath 4; five single-core coaxial cables are evenly distributed on the periphery of the central sheath. The axial cable 2 and the sheath 1 are wrapped around the periphery of the single-core coaxial cable. The jacket 1 has a double-layer structure, the inner layer is the jacket barrier layer 11 , and the outer layer is the jacket insulation layer 12 . The central sheath 4 also has a double-layer structure, its inner layer is the sheath barrier layer, and its outer layer is the sheath insulation layer.

Abstract

This invention relates to a multi-core coaxial and signal cable used by devices of radio base stations in zoom out of radio transmission or IF cable of analog IF in the TD-SCDMA base station system of the third generation of mobile communication including a cylindrical jacket and multiple single-core coaxial cables and multiple signal cables in the jacket, in which, the signal cables are wrapped in a cylindrical central jacket situated at the center of the jacket and the single coaxial cables are distributed around the central jacket uniformly and the jacket wraps the coaxial cables, which can reduce numbers of cables connecting indoor devices with outdoor RF subsystems of the TD-SCDMA radio base stations.

Description

technical field [0001] The invention belongs to the communication equipment technology, and relates to a multi-core coaxial and signal cable used in the third-generation mobile communication TD-SCDMA base station system, wireless base station equipment for remote transmission by radio frequency or analog intermediate frequency by intermediate frequency cable. Background technique [0002] Existing coaxial cables usually have a single-core structure, and its structure includes a central conductor, an insulating layer, a shielding layer and a sheath layer from the inside to the outside. In the wireless base station equipment of the traditional mobile communication system, the outdoor equipment of the base station is only equipped with a power amplifier / low noise amplifier module, and the radio frequency subsystem of the base station is composed of 4 (or 6) power amplifier / low noise amplifier modules and a control module. The cables run to the indoor equipment of the base stati...
