Symmetrical type transmission cable for digital simulation signal handling equipment

Abstract

The invention relates to a symmetry transmission cable of digit analogue signal processing device, which can be divided into four groups according to different colors, while each group comprises four cores arranged according to relative insulation sheathes with different color rings. The outer side of the cable is arranged with an environment-friend polymer cover layer, an aluminum composite band layer, a weave layer and a protective layer, wherein the aluminum composite band layer and the weave layer clamp a longitudinal ground wire to form a composite shield layer, the weave layer and the protective sleeve clamp a tear line longitudinally. The middle of each group of four cores is respectively and longitudinally arranged with an environment-friend stuff line, which section comprises a large circle with four cores, tangent engaged and fixed with one small circle of one environment-friend stuff wire. The invention can avoid error structural arrangement of four cores in large-length production, with reasonable twist distance, non disperse, non crack, uniform resistance, high interference resistance, high electromagnetic interference resistance, simple production, non fixer demand, simplified product structure, and reduced production cost.

Description

technical field [0001] The invention relates to a transmission cable, in particular to a symmetrical transmission cable for digital and analog signal processing equipment. Background technique [0002] With the development and progress of science and technology, a large number of electronic and communication equipment are used, and they are increasingly sophisticated, complex and multi-functional; and various electronic equipment are always troubled by the unstable quality of signal transmission cables. Since the current transmission cables are all made of high technology, the cable structure and electrical quality are the most important for a system. It can not only handle the internal signal transmission properly, but also completely transmit the internal signal of the system to the outside of the system. Therefore, equipment transmission cables play an extremely important role in transmission. Due to the large volume and poor performance of the cables used for digital an...

AI Technical Summary

Problems solved by technology

Due to the large volume and poor performance of the cables used for digital and analog signal processing equipment produced in the prior art, the defects of the cables themselves will directly 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.

Existing transmission cables for digital and analog equipment are generally complex in structure, expensive in cost, and bulky; the connection form is multiple point-to-point fixed connections

[0003] At present, most of the cables used in domestic digital and analog system equipment are imported from abroad, or some other cables with large volume, poor stability and high price are used, and the use effect is difficult to reach the expected level.

The production of such products in foreign countries often uses expensive high-end instruments and equipment to ensure the stability and reliability of their arrangement structure; however, the cost of manufacturing equipment required is quite staggering, resulting in high product prices, which has caused many domestic network operators to rely on such products. The price of the cable is scary

At the same time, some foreign manufacturers in the industry have created a great monopoly on this type of cable, which has greatly restricted the domestic market.

The products of the same purpose currently produced in China have complex manufacturing processes and consume a lot of manpower, material resources and financial resources
