Problems solved by technology

The main reason is that in addition to the relatively backward technology, the performance of the supporting cables cannot meet the technical requirements and use requirements of instruments and meters. It is also an important factor.
[0005] Under the development trend of this kind of instrumentation, higher requirements are put forward for the supporting cables, such as the stability of cable signal transmission, low loss, high reliability, anti-interference, and multi-functionality of use, etc. , while the existing traditional instrument cables, which sequentially set insulating layers, shielding layers and sheaths, etc. on the conductors, have been difficult to achieve the above functions at the same time

Embodiment Construction

[0016] Copper conductors and foamed polyethylene (PE) insulation materials that meet the relevant standards for instrument cables are used, and the skin-foam-skin three-layer co-extrusion and series production process is used to complete the conductor wire drawing and skin-foam-skin insulation process once. 1 has an insulated wire core with insulating inner skin 2, foam insulation 3, and insulating outer skin 4. Each pair of insulated wire cores is twisted into a pair of twisted wire groups, each pair of twisted wire groups is provided with a certain pitch, and multiple pairs of twisted wire groups of the cable core are respectively provided with different pitches. Twisted wire pairs 7 are formed by twisted shielding layers 6 longitudinally wrapped or wrapped with copper-plastic or aluminum-plastic film composite tapes on the twisted wire groups and drain wires 5 . The twisted wire pairs 7 are cabled in a certain order, and the outer surface of the cable core 10 is wrapped wit...

Abstract

This invention relates to a data precision instrument cable. An insulation layer of expanded PE material in skin-foam-skin co-extrusion is set on the conductor to form a core of the cable, multiple pair-groups of pair wires with pair twist screen layers are set in the core, each set wire is set with a conduction wire, the cable core is set with a gird, a general screen layer and an outer sheathing are set on it orderly and a conduction lead is set between them.

Description

technical field [0001] The invention relates to a cable structure, in particular to a cable structure for high-precision instruments and meters, and belongs to the technical field of cables. Background technique [0002] With the rapid development of science and technology and the continuous improvement of automation, the high-tech of my country's instrumentation products will surely become the mainstream of instrumentation technology and industry development. Over the past 20 years, high and new technologies such as microelectronics technology, precision machinery technology, special processing technology, network technology, nanotechnology, superconducting technology and biotechnology have developed rapidly. This background and situation constantly proposes faster speed, higher sensitivity, better stability, less sample volume, minimal or even non-destructive detection, longer distance remote sensing and telemetry, more convenient use, lower cost, Higher, newer, and more ...
