Abstract
The utility model relates to a polyfluorinated ethylene propylene and inflaming retarding polyvinyl chloride double insulation light flexible wire and a shielding flexible wire, which are characterized in that an inner conductor is made of a plurality of skein tinned circular copper wires; an insulating layer is insulated by a two-layer thin wall; the nominal thickness of the whole two-layer insulator is 0.30 mm, particularly the nominal thickness of internal insulating of the polyfluorinated ethylene propylene is 0.10 mm; a shielding layer adopts a composite plastic-aluminum belt wrapping mode instead of the conventional weaving structure; and a protective layer is made of 80 DEG C inflaming retarding polyvinyl chloride. The utility model has the advantages that: 1, the utility mode have the advantages of flexibility, easy bending, small volume and light weight; and 2, the utility model can achieve the requirements of products without delaying inflaming, environment tolerant performance, favorable bending performance and the like.
Description
Technical field
The utility model relates to a kind of light-duty flexible cord and shielding flexible cord, relates in particular to a kind of perfluoroethylene-propylene, the two light-duty flexible cords of insulation of flame-proof polyvinyl chloride and shielding flexible cord.
Background technology
Continuous development along with national high-tech sector, traditional air defense (being surface-to-air ballistic missile) is extended to higher field, the effect spatial domain also expands to the exoatmosphere from the endoatmosphere, and the more and more miniaturization of guided missile individuality impels the guided missile electrical system also constantly to miniaturization, integrated development.Cable system is the part of guided missile electrical system interwoveness on the bullet, and it is the carrier that plays information flow entirely, is again the basis that plays co-ordination entirely, realizes the full distribution transmission that plays the presenting of electric energy, measurement and control signal etc. by cable system.Physically, it is the cable assembly that is processed through corresponding technological requirement by the lead of certain type and specification and electric connector.Just formed full bullet information exchange platform by the network that it constitutes.
Because cable system is worked in the environment on abominable bullet on the bullet, this just requires it must have reliability more than 0.997, and carries out effective electromagnetic Compatibility Design at different characteristics of signals.With cable system designing requirement on the guided missile bullet of new generation that reaches " complete function, small light, rational in infrastructure, high reliability and Electro Magnetic Compatibility ".
Summary of the invention
The purpose of this utility model is to provide two light-duty flexible cords of insulation of a kind of perfluoroethylene-propylene, flame-proof polyvinyl chloride and shielding flexible cords, and it is applicable to connecting line and the signal transmssion line of making instrument, equipment in the environment of high low temperature situation.
The utility model is achieved like this; it comprises inner wire, insulating barrier, screen, protective layer; it is characterized in that the peripheral insulating barrier that connects of inner wire; the peripheral screen that connects of insulating barrier; the peripheral protective layer that connects of screen; inner wire adopts the some zinc-plated circular copper wires of bundle strand; insulating barrier adopts the double-layer thin wall insulation; whole double hyer insulation body nominal thickness is 0.30mm; particularly the nominal thickness of insulation is 0.10mm in the perfluoroethylene-propylene; screen replaces traditional woven structure with the wrapped form of compound plastic-aluminum band, and protective layer adopts 80 ℃ of flame-proof polyvinyl chlorides.
Technique effect of the present utility model is: 1, have soft pliable folding, little, the lightweight advantage of volume; 2, satisfy product and do not prolong requirements such as combustion, environmental resistance, good bending property.
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; it comprises inner wire 1; insulating barrier 2; screen 3; protective layer 4; it is characterized in that the inner wire 1 peripheral insulating barrier 2 that connects; the insulating barrier 2 peripheral screens 3 that connect; the screen 3 peripheral protective layers 4 that connect; inner wire 1 adopts the some zinc-plated circular copper wires of bundle strand; insulating barrier 2 adopts the double-layer thin wall insulation; whole double hyer insulation body nominal thickness has only 0.30mm; particularly the nominal thickness of insulation has only 0.10mm in the perfluoroethylene-propylene, and screen 3 replaces traditional woven structure with the wrapped form of compound plastic-aluminum band, and protective layer 4 adopts 80 ℃ of flame-proof polyvinyl chlorides.Because of its ultra-thin insulation nominal thickness has only 0.10mm.Simultaneously, the melt temperature of fluoroplastics is than higher, its processing temperature reaches as high as degree more than 400, the PVC or the PE that use always with us are very different, thereby at the design aspect of product expressing technique and extrusion die, quite take the time, and equipment and the moulds of industrial equipment of producing the fluoroplastics electric wire must be corrosion-resistant, we are by field adjustable and process certification, determined a series of technological parameter and the control method such as manufacturing materials, die size, heating-up temperature, mould proportioning of extrusion die, different draw ratios is realized insulating and the shaping of sheath extrudes by regulating.The utility model is not only realized single insulated wire cores, also can be two eradication edge cores.
