Abstract
The utility model discloses an armor signal line, including sinle silk, conducting layer, insulating layer, shielding layer and the armor that sets gradually from inside to outside. The utility model discloses a but flexible fibers restraints as the sinle silk to use the conducting layer to twine in the sinle silk surface, and make the signal line have lower impedance, simultaneously, utilize insulating layer, shielding layer and armor to carry out multiple protection to the signal line respectively, improved the interference killing feature of signal line greatly, have advantages such as corrosion -resistant, high temperature resistant, high pressure resistant, that hardness is big, can effectively increase signal line life.
Description
Technical field
This utility model belongs to data signal transmission technical field, particularly relates to a kind of armouring holding wire.
Background technology
At present, the holding wire in market is of a great variety, Various Functions.It is known that holding wire is mainly made up of core, insulating barrier, screen layer and overcoat, outside core, successively coated insulation layer, screen layer and overcoat form cable.But, under common signal line application to high temperature, environment under high pressure or rich in time in the environment of the chemicals such as strong acid-base, polymer, ternary, there is a lot of problem, such as: 1, overcoat is easily corroded, shorten cable service life；2, cable seal is poor, is easily caused oil gas and reveals, to environment；3, in water injection well layering is tested, water constantly overflows from steel wire gap, causes well pressure shakiness, affects measurement result.Additionally easily freeze during use in winter, directly affect the test of downhole parameters；4, barrier layer functionality is more weak, is easily caused the problems such as signal attenuation, distortion be big.5, cable entirety is the softest, for hole deviation more than the producing well at 60 degree of angles, is extremely difficult to the layer position estimated, carrys out band difficulty to well logging.6, core easily snaps off, and affects signal transmission.
Summary of the invention
Goal of the invention of the present utility model is: in order to solve problem above present in prior art, the utility model proposes the armouring holding wire that a kind of impedance is low, corrosion-resistant, high temperature resistant, high pressure resistant, hardness is big.
The technical solution of the utility model is: a kind of armouring holding wire, including the core set gradually from inside to outside, conductive layer, insulating barrier, screen layer and armor；Described core uses pliability fibre bundle；Described conductive layer includes that many have the parallel of same circular cross-section and connect metal wire；Described metal line surface is coated with insulating lacquer layer, and is helically wound around described core surface, in can continuous conduction structure.
Further, described insulating barrier uses perfluoroalkoxy resin material.
Further, described screen layer uses silver-plated copper mesh.
Further, described armor uses steel wire armor layer or rustless steel armor.
The beneficial effects of the utility model are: this utility model employing pliability fibre bundle is as core, and uses conductive layer to be wound in core surface, and makes holding wire have relatively low impedance；Meanwhile, it is utilized respectively insulating barrier, screen layer and armor and holding wire is carried out multiple-protection, substantially increase the capacity of resisting disturbance of holding wire, there is the advantages such as corrosion-resistant, high temperature resistant, high pressure resistant, hardness is big, can effectively increase holding wire service life.
Accompanying drawing explanation
Fig. 1 is a kind of armouring signal line structure schematic diagram of the present utility model.
Wherein, core 1, conductive layer 2, metal wire 21, insulating barrier 3, screen layer 4, armor 5.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As it is shown in figure 1, be a kind of armouring signal line structure schematic diagram of the present utility model.A kind of armouring holding wire, including the core 1 set gradually from inside to outside, conductive layer 2, insulating barrier 3, screen layer 4 and armor 5；Described core 1 uses pliability fibre bundle；Described conductive layer 2 includes that many have the parallel of same circular cross-section and connect metal wire 21；Described metal wire 21 Surface coating has insulating lacquer layer, and is helically wound around described core 1 surface, in can continuous conduction structure.
The pliability fibre bundle that core 1 of the present utility model uses plurality of fibers to be formed, thus improve the resistance to tortuosity of core；Conductive layer 2 use three to five metal wires with identical circular cross-section 21 in the way of will not overlapping, the most parallel and connect and be helically wound around core 1 surface, make metal wire 21 in the length direction of core 1 in can the structure of continuous conduction；Metal wire 21 can use copper cash or other conductivity more material, and its Surface coating has insulating lacquer layer, it is achieved with the effect of external insulation；Make that holding wire external diameter is less, impedance is lower, elastic and resistance to tortuosity repeatedly is good, handling ease, it is not easy to produce broken string because processing is bad, reduce production cost.
Insulating barrier 3 of the present utility model uses perfluoroalkoxy resin material, further increases the insulating properties of holding wire.
Screen layer 4 of the present utility model uses silver-plated copper mesh, and capacity of resisting disturbance is strong so that signal transmission is purer.
Armor 5 of the present utility model uses steel wire armor layer or rustless steel armor, and mechanical resistant is damaged, and greatly strengthen holding wire intensity, increases service life.
Those of ordinary skill in the art is it will be appreciated that embodiment described here is to aid in reader understanding's principle of the present utility model, it should be understood that protection domain of the present utility model is not limited to such special statement and embodiment.Those of ordinary skill in the art can make various other various concrete deformation and combination without departing from this utility model essence according to these technology enlightenment disclosed in this utility model, and these deformation and combination are still in protection domain of the present utility model.
