Problems solved by technology

Due to the large volume and poor performance of the cables produced by the existing technology, the defects of the cables themselves will affect the quality of the transmitted signal, thereby interfering with the signal processing equipment, which is very unfavorable for signal processing
In addition, due to the complex structure, high-end equipment is required to guarantee it, and the processing difficulty and manufacturing cost are relatively high.
The existing signal connection form between field equipment or laboratory equipment is multiple point-to-point fixed connections. This connection method has the defects of complicated wiring and inconvenient use.
At the same time, the existing cables have poor flame retardancy and are easily ignited in the event of a fire

Embodiment Construction

[0023] Below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure and features provided by the present invention are described in detail as follows:

[0024] Examples see figure 1 , figure 2 , the cable consists of a cable layer and a sheath. The cabling layer consists of 8-core coaxial cables 1-8, and the cabling structure is divided into 2 layers according to the layering order of 1+7, and it can also be 2 cores, 4 cores, 12 cores, 32 cores or other numbers. For post-processing needs, No. 1-8 inkjet codes are printed on the front and rear ends of the inner sheath 16 of each core wire coaxial cable. The arrangement order is arranged according to the different printing on the inner sheath of the core wires. One or more coaxial core wires are wrapped with a polyester film 9 in the cable layer. A tear line 10 is provided. The core wire is a 0.26mm silver-plated copper conductor 12, and each core wire conductor has a...

Abstract

The invention belongs to a cable, in particular relates to an ultramicro signal transmission coaxial cable which comprises a cable forming layer and a jacket. The ultramicro signal transmission coaxial cable is characterized in that the cable forming layer comprises one or a plurality of coaxial core wires, an insulating layer is arranged outside each core wire conductor, a shielding layer which is formed by knitting tinning copper wires is arranged outside the insulating layer, a low smoke and zero halogen inner jacket is arranged outside the shielding layer, a polyester film is wrapped outside the cable forming layer with one or a plurality of coaxial core wires, and a low smoke and zero halogen outer jacket is arranged outside the polyester film. Compared with the prior art, the invention has the advantages of stable structure, reliable performance, compact volume, environmental protection, no pollution and lower industrial manufacturing cost.

Description

technical field [0001] The invention belongs to electric cables, in particular to an ultramicro signal transmission coaxial cable. Background technique [0002] In a telecommunications system, cables are spread throughout the body like human blood vessels, responsible for power supply and signal control transmission to ensure the normal operation of the system. With the rapid development and progress in the field of telecommunications, a large number of applications of electronic and communication equipment, the use of signal transmission cables has increased dramatically. Since the current transmission cables are all manufactured with high technology, the wire diameter is huge, and polyvinyl chloride is used as the sheath, so the anti-interference performance is poor. Therefore, as far as a system is concerned, the cable structure and electrical quality can not only properly handle internal signal transmission, but also completely transmit the internal signal of the system...
