Abstract
The invention discloses a copper and yarn shielding sleeve pipe, which is characterized in that the sleeve pipe is formed by weaving copper wires with teflon yarns through oil-proof and waterproof processing, and meanwhile, a PTFE (Polytetrafluoroethylene) sealing tape is additionally installed on an inner layer to be used as an inner-layer auxiliary material. The copper and yarn shielding sleeve pipe disclosed by the invention can be applied to acid-resistant, alkali-resistant, oil-resistant and high-temperature-resistant environments, the long-term working temperature can reach as high as 150 DEG C, and the copper and yarn shielding sleeve pipe can instantaneously resist the high temperature of 220 DEG C; moreover, the copper and yarn shielding sleeve pipe has the advantages of low material thermal-expansion coefficient, good wear-resistant performance, strong shock-resistant capability, long service life, convenience in installation, good fitting capability with pipelines and lines, light weight and good signal shielding; maintenance and repair expenses are lowered; a clamping hoop can also be enabled to bear the vibration and friction of an airplane, so that the airplane operating safety and the fastening and fixing reliability are improved.
Description
Technical field
The present invention relates to a kind of copper to hold concurrently yarn shielded tube.
Background technology
Copper yarn shielded tube of holding concurrently is widely used in the pipe connection system of engine in Aeronautics and Astronautics industry, in electronic system circuit and pipe-line system, plays protection, shielding action to pipeline, circuit.In these industries, require high to properties of product, to the material of product, intensity, structure, the performance requirements such as weight are higher, and other products non-can substitute.General product, when these industry applications, cannot meet the requirements such as high temperature, high strength, shield effectiveness be good, lightweight.Traditional shell material oil resistant, acid-alkali-corrosive-resisting, resistance to elevated temperatures are poor, cannot use for some particular surroundingss; Traditional sleeve weight is large, increases aircraft load, can not meet some extraordinary occasion instructions for use.
Summary of the invention
The present invention is directed to the proposition of above problem, and develop a kind of copper and to hold concurrently yarn shielded tube.The technological means that the present invention adopts is as follows:
A kind of copper is held concurrently yarn shielded tube, and it is characterized in that this sleeve pipe again through forming through grease proofing and water-proofing treatment after being woven by copper wire and Teflon yarn, internal layer installs PTFE raw material band additional as internal layer auxiliary material simultaneously.
Copper of the present invention yarn shielded tube of holding concurrently can be applied to acid and alkali resistance, oil resistant, and in resistant to elevated temperatures environment, Long-term service temperature can up to 150 DEG C, instantaneous can resistance to 220 DEG C of high temperature, and material thermal expansion coefficient is low, and anti-wear performance is good, and shock resistance is strong.Long service life, reduces maintenance and repair expense.Easy for installation, with pipeline, the laminating degree of circuit is good, lightweight, and shielded signal is good, can also ensure that clip can bear vibration and the friction of aircraft, improves the fail safe that aircraft runs and the reliability be fastened and fixed.This sleeve pipe is convenient to produce, and cost is very cheap is suitable for extensive popularization.
Accompanying drawing explanation
Fig. 1 is sleeve structure schematic diagram of the present invention;
Fig. 2 is the appearance schematic diagram of sleeve pipe of the present invention.
In figure: 1, copper wire, 2, Teflon yarn, 3, PTFE raw material band, 4, cable.
Embodiment
As depicted in figs. 1 and 2 a kind of copper hold concurrently yarn shielded tube woven by copper wire 1 and Teflon yarn 2 after again through forming through grease proofing and water-proofing treatment, internal layer installs PTFE raw material band 3 additional as internal layer auxiliary material simultaneously.This sleeve pipe can be used for tying up and protects cable assembly, wire harness and EMI electromagnetic shielding, and its internal layer can also install PTFE raw material band additional as internal layer auxiliary material, protection wire harness.
The braiding of copper wire, Teflon yarn makes that to have shielded signal good, lightweight, and shielding strength products of the same race compares lightweight 20%.Install PTFE raw material band additional as internal layer auxiliary material, protection wire harness.Through grease proofing and water-proofing treatment, can prevent from absorbing the extreme variation received due to aircraft and the condensation assembled.According to in-site installation requirement during use, carry out encapsulation and be inserted in, cable 4 is sleeved in sleeve pipe.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
Claims (1)
1. copper is held concurrently a yarn shielded tube, and it is characterized in that this sleeve pipe again through forming through grease proofing and water-proofing treatment after being woven by copper wire (1) and Teflon yarn (2), internal layer installs PTFE raw material band (3) additional as internal layer auxiliary material simultaneously.
