Embodiment
, easily loose, bend resistance scarce capacity bad for signal controlling drag chain cable globality in prior art, and the shortcoming such as the life-span is relatively short, the utility model provides a kind of signal controlling drag chain cable, by the first lapping layer adopting fiber paper tape to make at electric wire core outer cladding one deck, good fixation is had to the electric wire core that there is multiple insulated wire cores stranded, can ensure that electric wire core becomes an entirety, ensure that insulated wire cores is not at random, and the useful life of extending wire cable; The second lapping layer made by increase cotton paper or cotton between braid and outer jacket, internal drag when bending is mobile between braid and outer jacket can be reduced, thus uniform force inside and outside guarantee electric wire, thus strengthen the bend resistance ability of electric wire; Be filled with packed layer by the gap between many insulated wire cores and between insulation core wire and the first lapping layer, insulation core wire can be protected from destruction; Prepare by the insulating barrier of electric wire, inner covering and outer jacket being adopted respectively the modified polyvinyl chloride material of different flexible label; good protective effect is had to electric wire structural integrity; thus extend the useful life of electric wire further, strengthen the bend resistance ability of electric wire further simultaneously.
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 further elaborated.Should be understood that, specific embodiment described herein only for explaining the utility model, and is not used in restriction the utility model.
Fig. 1 is the cross section structure schematic diagram of the signal controlling drag chain cable of the utility model preferred embodiment.Signal controlling drag chain cable comprises many insulation core wires 1, first lapping layer 2, inner covering 3, braid 4, second lapping layer 5 and outer jacket 6.Wherein, many insulation core wires 1 are twisted into electric wire heart yearn, first lapping layer 2 is wrapped outside electric wire heart yearn by stranded operation, this first lapping layer 2 is made up of fiber paper tape or fiber cloth material, to the electric wire heart yearn be twisted into by many insulation core wires 1, there is good fixation, can ensure that electric wire becomes as a whole and not at random.
This inner covering 3 is coated on outside the first lapping layer 2, and this inner covering 3 adopts a kind of soft durometer label to be that the modified polyvinyl chloride that the flexibility of 50P-70P is high is made, and is coated on outside the first lapping layer 2 by thermoplastic extrusion technique.Wherein, flexible high modified polyvinyl chloride material, usual employing how many P i.e. Pa (handkerchief) represents soft durometer, refer to the content of plasticizer in modified polyvinyl chloride material, therefore P value is higher, and namely the numerical value of Pa is larger, and the content of plasticizer is also more, material is also softer, and soft durometer label is that 50P-70P represents that its Pa Shi hardness number is 50-70.Employing soft durometer label is that the modified polyvinyl chloride that the flexibility of 50P-70P is high has good protective effect to electric wire structural integrity, thus extends the useful life of electric wire further, strengthens the bend resistance ability of electric wire further simultaneously.
This braid 4 is woven by many tinned copper wires and forms, and is coated on outside inner covering 3, and this braid 4 can increase shield effectiveness, is understandable that, this braid 4 also can be that aluminium foil is made.In the present embodiment, the filament diameter of each root tinned copper wire is less than 0.1mm, and the braid 4 woven by soft tinned copper wire is relative to the braid 4 of lagging cover tin proof copper-wire braided, and its shield effectiveness is better.
Outer jacket 6 is coated on outside braid 4, and this outer jacket 6 adopts a kind of soft durometer label to be that the modified polyvinyl chloride that the flexibility of 60P-80P is high is made, and is coated on outside braid 4 by thermoplastic extrusion technique.The thickness of this outer jacket 6 is 0.6mm-0.8mm.Employing soft durometer label is that the modified polyvinyl chloride that the flexibility of 60P-80P is high has good protective effect to electric wire structural integrity, thus extends the useful life of electric wire further, strengthens the bend resistance ability of electric wire further simultaneously.

In the utility model, each root insulation core wire 1 comprises the insulating barrier 12 of conductor 11 and coating conductor 11 from inside to outside successively.Wherein, conductor 11 is twisted by many copper wire bundles to form.Be different from blister copper silk of the prior art, in the utility model, adopt many soft copper wire bundle strands to make insulation core wire 1, the filament diameter of the soft copper wire used all is less than or equal to 0.18mm, and the monofilament elongates rate of described copper wire is more than 30%.Filament diameter is little, the quantity of the blister copper silk that the quantity of the soft copper wire that the conductor 11 making same external diameter uses uses in prior art, and this can effective dispersed suffered external force; Monofilament elongates rate height illustrates that copper wire is soft, ductility strong, and bend resistance ability is strong.So the signal controlling drag chain cable that the utility model uses described soft copper wire to obtain has extremely strong bend resistance ability, through exceeding millions of time come and go bending motion after can not rupture, and then guarantee the physics of signal controlling drag chain cable and electric property unaffected.
In the present embodiment, many soft copper wires are stranding into conductor 11 by bundle, the twisting pitch of bundle strand is less than 18 times of stranded external diameter and has stronger intensity and bend resistance ability with the conductor 11 guaranteeing to obtain.
Be that modified polyvinyl chloride that the flexibility of 38P-45P is high is wrapped in and forms insulating barrier 12 by conductor 11 outside by a kind of soft durometer label, and then obtaining the insulation core wire 1 of composition signal controlling drag chain cable, it is outside that this insulating barrier 12 is coated on conductor 11 by thermoplastic extrusion technique.The modified polyvinyl chloride that this flexibility is high has the anticorrosive property of super flexible, extremely strong resistance to tearing and excellence, the useful life of energy significant prolongation signal controlling drag chain cable.The thickness of insulating barrier 12 is 0.2mm-0.6mm, and compared with common insulating barrier, its thickness reduces half, reduces the quality of cable and does not affect the result of use of cable.
In addition, in the present embodiment, electric wire core forms by four insulation core wires 1 are stranded.Be understandable that, electric wire core can by two or three, and even form more than the insulation core wire 1 of four is stranded, can select according to actual needs, this is not restricted.
In the utility model, gap between many insulation core wires 1 is filled with packed layer 7, this packed layer 7 includes high flame retardant glass fiber material, packed layer 3 is filled in the gap between cable inner core 2, namely when insulation core wire 1 is many, when these many insulation core wires 1 arrange in the first lapping layer 2, between insulation core wire 1 or between the first lapping layer 2 and insulation core wire 1, have space.The glass fiber material including high flame retardant is filled in these gaps, forms packed layer 7.Packed layer 7 adopts the wrapped formation of high flame retardant glass fiber material, can prevent flame from internally permeating, and protection insulation core wire 1 is from destruction.In other embodiments, packed layer 7, except including high flame retardant glass fiber material, also includes semiconductive water-proofing powder, stops water to vertically move to electric wire, then both made electric wire breakage also can continue conduction in a humidity environment, and strengthened waterproof effect.
