Description
[technical field]
The utility model relates to field of cable technology, particularly the soft Teflon coaxial cable of a kind of PTFE with wrapped sheath.
[background technology]
The mode of restrictive coating many employings extruder for shaping of tradition Teflon coaxial cable realizes, in shaped article, restrictive coating is connected defective tightness with outer conductor, beaming limit is little, further, during jacket extrusion forming, need special equipment, when the cable in different path is extruded, need different moulds, to joining mode coefficient and draw ratio has higher requirement, sometimes because the restriction of equipment, mould or material, the environmental test such as anti-stress cracking and cold bend(ing) cannot meet, and it is more that process produces defect; In addition, PTFE is adopted to be with lapping structure although existing Teflon coaxial cable sheath layer has, but just simple machinery is low wrapped, such PTFE with wrapped restrictive coating once carry out wire stripping process or centre PTFE band rupture, PTFE band can be loose very soon, and therefore the cable of this structure is difficult to be promoted on a large scale.
[summary of the invention]
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide the soft Teflon coaxial cable of a kind of PTFE with wrapped sheath, while possessing existing coaxial cable advantage, bending property improves greatly, and restrictive coating is not easy loose, rational in infrastructure.
For solving the problems of the technologies described above, the utility model have employed following technical proposals:
The soft Teflon coaxial cable of PTFE with wrapped sheath, comprises from inside to outside coaxial inner wire, insulating barrier, outer conductor and the employing high density PTFE arranged successively and is with the restrictive coating of wrapped rear sintering, and the wrapped overlapping rate of described restrictive coating is not less than 50%.
Preferably, the density of described high density PTFE band is 1.6g/cm
3.
Preferably, the overlapping rate that described restrictive coating is wrapped is 50%.
Preferably, described outer conductor comprises silver-coated copper wire lapping layer, and is woven in the tinned wird braid outside silver-coated copper wire lapping layer.
Preferably, described inner wire is silver-plated copper conductor.
Preferably, described insulating barrier is teflon insulation layer.
Compared with prior art, the beneficial effects of the utility model are: restrictive coating adopts high density PTFE to be with wrapped rear sintering to form, and the bending property of cable improves greatly, and the density of high density PTFE band is 1.6g/cm
3, wrapped overlapping rate is not less than 50%, and the PTFE of this structure is with viscosity large, and after 250 DEG C of sintering, PTFE viscosity strengthens greatly, and PTFE sticks together between layers, and become an overall formation restrictive coating, after cable cutting, restrictive coating can not be loose, safe and reliable.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the utility model one embodiment.
[embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is described further.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the soft Teflon coaxial cable of PTFE with wrapped sheath, comprise inner wire 1, insulating barrier 2, outer conductor 3, the restrictive coating 4 of coaxial setting successively from inside to outside, described restrictive coating 4 adopts high density PTFE to be with wrapped rear sintering to form, and the wrapped overlapping rate of restrictive coating 4 is not less than 50%.
High density PTFE is with lapping structure formation restrictive coating 4 to enhance pliability and the heatproof intensity of cable, and not easily occur cracking phenomena time bending, bending resistance is strong.
Restrictive coating 4 adopts high density PTFE to be with wrapped rear sintering to form, and the bending property of cable improves greatly, and the density of high density PTFE band is 1.6g/cm
3, wrapped overlapping rate is 50%, and the PTFE of this special construction is with viscosity large, after 250 DEG C of sintering, PTFE viscosity strengthens greatly, and PTFE sticks together between layers, becomes an overall formation restrictive coating 4, after cable switches, restrictive coating can not be loose, safe and reliable.
Described outer conductor 3 comprises silver-coated copper wire lapping layer, and is woven in the tinned wird braid outside silver-coated copper wire lapping layer, this arrangement enhances the shield effectiveness of cable, also improves steady phase performance simultaneously, and cable is when bending, and phase place change is little.
Described inner wire 1 is silver-plated copper conductor, is made up of silver-gilt copper wire, by silver-plated for the copper wire resistance that can increase electric wire, makes cable can bear larger voltage.
Described insulating barrier 2 is teflon insulation layer, and teflon insulation layer has good anti-flammability and anti acid alkali performance energy.
High density PTFE of the present utility model is with wrapped viscosity large, becomes an overall formation restrictive coating 4, have softness, resist bending, high temperature resistant, not loose advantage, rational in infrastructure, use safety after wrapped.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection range that all should belong to the utility model claims.
