Abstract
The utility model relates to an aerospace polyimide and polytetrafluoroethylene dual-layer film lapped insulated wire cable, which is characterized in that the periphery of an inner conductor is connected with a polyimide film lapping and insulating layer, the periphery of the polyimide film lapping and insulating layer is connected with a polytetrafluoroethylene film lapping and insulating layer, and the inner conductor is a silver-plated flexible round copper wire. The aerospace polyimide and polytetrafluoroethylene dual-layer film lapped insulated wire cable has the technical effects of high-temperature and low-temperature (negative 65 DEG C to 200 DEG C) resistance, small volume, light weight, no thermal contraction, excellent mechanical toughness, salt fog resistance, damp and heat resistance and excellent high-radiation resistance, and can provide reliable service in hostile environments.
Description
Technical field
The utility model relates to a kind of electric wire, relates in particular to a kind of Aero-Space polyimides, polytetrafluoroethylene bilayer film lapped insulation electric wire.
Background technology
Though China is electric wire big producing country, but military project Aero-Space usefulness electric wire production technology is U.S.'s Raychem monopolization always, and some high end cables mainly still are dependence on import.The formal enforcement of the big aircraft project localization rate of parts and components of country has determined that the situation of long-term dependence import can not long term maintenance, and along with project implementation, it is supporting to promote Aero-Space cable oneself, with substituting import one, improves the big aircraft project localization rate of parts and components.
Domestic manufacturer starts to develop this series products of development at present, makes progress.But owing to be subjected to raw-material restriction, the factory building of initial investment, equipment, frock and production capacity a little less than, technology is difficult for the reason of aspects such as grasp, domestic many producers ability is not produced this product.Succeeding in developing of this project can be broken the monopoly position of foreign corporation in this field, fills up a blank in China Aero-Space Special Wires and Cables field, changes the situation of the long-term dependence on import of China's Aero-Space Special Wires and Cables.
Summary of the invention
The purpose of this utility model is to provide a kind of Aero-Space polyimides, polytetrafluoroethylene bilayer film lapped insulation electric wire, this electric wire electric property, mechanical and physical performance are good, volume is little, in light weight, the security reliability height is high-performance first-selected in the current aerospace field, the top light-duty electric wire of high reliability.
The utility model is achieved like this, it comprises inner wire, polyimide film lapped insulation layer, polytetrafluoroethylene film lapped insulation layer, it is characterized in that the peripheral polyimide film lapped insulation layer that connects of inner wire, the peripheral polytetrafluoroethylene film lapped insulation layer that connects of polyimide film lapped insulation layer, described inner wire is silver-plated soft circular copper wire.
The structure of described inner wire is the twisted wire type.
Technique effect of the present utility model is: have that high-low temperature resistant (65 ℃～200 ℃), volume are little, in light weight, not thermal contraction and a remarkable mechanical tenacity, can prevent salt fog, prevent damp and hot and excellent anti-high radiation, reliability services can be provided in rugged environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is achieved like this, the inner wire 1 peripheral polyimide film lapped insulation layer 2 that connects, the polyimide film lapped insulation layer 2 peripheral polytetrafluoroethylene film lapped insulation layer 3 that connects, described inner wire is silver-plated soft circular copper wire.This product inner wire adopts silver-plated soft circular copper wire, is the characteristics such as electric property that solderability is good, reliability is high and good of considering that silver-coated copper wire has, and simultaneously, the structure of inner wire is the flexibility that the twisted wire pattern also can increase product; Insulation and sheath adopt polyimide film lapped insulation layer 2 and polytetrafluoroethylene film lapped insulation layer 3 to consider from three aspects: the one, and the restriction that is subjected to extrusion temperature and mould that the pattern of lapped insulation and sheath exists when not produced by general insulation and sheath, insulation and jacket thickness are controlled easily, and the finished cable of production is soft light and handy; The 2nd, have broad operating temperature range, serviceability temperature can guarantee that product can adapt to high low temperature operational environment between-60 ℃～+ 250 ℃; The 3rd, high-temperature insulation, sheath material have the arc resistance energy; Silver-plated soft circular copper wire braided outer conductor has guaranteed the high shielding and the flexibility of product.Above-mentioned material and technology have fully guaranteed this product applicable under the harsh and unforgiving environments such as Aero-Space, the high reliability of good bending property, electric property, environmental resistance and product.
