Description
Technical field
The present invention relates to a kind of flame retardant plastics insulation conductive strips, particularly a kind of electrical control cabinet and the outdoor lead-in of range transformer, fixedly connected line of the electric energy transmitting in the genus electric field of being used for.
Background technology
So far, in the outdoor lead-in of various electrical control cabinets, transformer, fixedly connected line as electric energy transmitting, there are the copper rod that adopts the electric conductivity excellence, some copper wires to be twisted into the copper cable etc. of strand shape, but single piece of copper strips of more employings, because copper rod, copper cable exist the contact area because of connecting little, the defective that is difficult to bear big electric current, copper strips is quite different.Yet copper strips also has unsuitable crooked drawback, is easy to crooked flexibility so copper strips is had, and is the thorny problem that people thirst for solving.In addition, the above-mentioned single piece of copper strips that is connected with electrical control cabinet, transformer as outdoor lead-in is that dew is naked, lacks insulating barrier as protective medium, has the hidden danger of secure context.
US5804768 relates to a kind of surface and is coated with the flat leads of using of multilayer more, by shown in Figure 1, lead 10, it is by the multilayer strap 11 of at least two unit, plating coating 11a in every layer of strap 11 surfaces, 11b, 11c, binding material 13 and insulating barrier 15, outer jacket 17 is formed, the effect of binding material 13 is that multilayer strap 11 bondings of original separate unit are as a whole, by its description as can be seen, the lead of this structure only can be used for the light current transmission, as is applied to the electronics wiring, telephone wiring, wiring amplifies, low voltage wiring, cable TV wiring and socket wiring etc.Exist shortcoming to be: 1,, to adopt a large amount of binding material 13, thereby increased the volume of lead 10 for multilayer strap 11 combinations with each unit; 2, with regard to the multilayer strap 11 of a unit, do not combine between layer and the layer not superimposedly, just because of this structure, not only soft bendability is restricted, and can't be adapted to as electrical control cabinet under the big electric current and the outdoor lead-in of range transformer.
Chinese patent publication number CN1224221A has introduced a kind of flat cable, and its technical problem to be solved is intended to satisfied the transmission such as the positive and negative signal of telecommunication that turns around between the parts of tens of circles of the low speed of vehicle steering control stick with the bar cover and is connected.Claim by this documents, specification and accompanying drawing thereof can know clearly, though it also is to have adopted one or more layers of conductive metal band, and each layer also divides and is set as some conductiving metal strips, see shown in Figure 2, it comprises two layers of conductive metal band 1,2, and conductive metal band 1,2 constitute conductiving metal strip 1a again respectively, 1b, 1c and 2a, 2b, at two layers of conductive metal band 1, reach two outsides insulating material film 3a between 2,3b, 3c separates, and then at conductiving metal strip 1a and 1b, the filling thermal synthesis layer is separated again in the hole between 1b and 1c and 2a and the 2b.As seen no matter what layer conductive metal band it adopts, and how many root conductiving metal strips no matter every layer of conductive metal band be divided into, necessary do insulation separation between them.Why it is this structure, mainly is the mixed biography that guarantees that it can satisfy the transmission multichannel weak current signal of telecommunication (Fig. 1 can be used for transmitting five kinds of different signals of telecommunication) and prevent the signal of telecommunication.One of shortcoming, the flat cable of this structure see and are multilayer that essence upper strata and interlayer are incoherent mutually, can not also can't be used as the electrical control cabinet under the heavy current, the outdoor lead-in of range transformer obviously; Two, above-mentioned flat cable still all must form clock and watch method strip dispatching from the factory under user mode, and must be provided in a likeness in form to it and place in the flat box of film copy and use, otherwise can can't use because of snarl; Three, its length is according to the difference of automotive type and predefined, intercept one section application so can not get arbitrarily from length, so its length is subjected to the restriction of specific practical application length in fact shortly; Four, insulating material film 3a, 3b, 3c adopt polyester or polyimides, do not have anti-flammability.
The Chinese patent publication number is that 1244020A relates to a kind of multi-layer flat electric cable, it is to be folded and form along fold domain A, B, C with the folding fan principle by one to five layer of mutual continuous thin slice band 1a shown in Figure 3, for fear of causing the plastic coating at this place to break because of folding at fold domain A, B, C place, form several weakening portions 2 of longitudinal extension at fold domain A, B, C place respectively, and still keeping connecting between several weakening portions 2 by connecting portion 3.The flat cable shortcoming 1 of this structure, be put to use after folding and in use can not be crooked, otherwise very easily produce the folding line fracture at connecting portion 3 places.Yet the desired stube cable of outdoor lead-in that is used for electrical control cabinet and range transformer is exactly in keep with flexibility; 2, it has formed one to five layer and even more multi-layered in form, but because the two sides of every layer of thin slice band Ia is to completely cut off with plastic coating mutually, therefore, as shown in Figure 3, it constitutes in fact only is by the connecting portion 3 thin slice band 1a of one piece of integral body that come structure with several same units 4a, 4b, 4c, 4d, promptly one piece of thin slice belt lead because be not electrically connected between the superposed surfaces of unit 4a, 4b, 4c, 4d, and is only realized being electrically connected by the connecting portion 3 at each lateral margin place; 3, the skin of this multi-layer flat electric cable does not have fire-retardant plastics protection, and anti-flammability also can't ensure; 4, the layer after folding with layer between be in fluffy state.
Summary of the invention
Task of the present invention be to provide a kind of can be soft crooked, fail safe is good, length is unrestricted, overall structure is compact, be suitable for use as under the big current applications the outdoor flame retardant plastics that is connected lead with the kind equipment transition of indoor electric cabinet and the transformer conductive strips that insulate.
Task of the present invention is finished like this, and a kind of flame retardant plastics insulation conductive strips comprise copper strips 1, described copper strips 1 comprises 2 pieces of copper bars 2 at least, and closely superimposed mutually between the copper bar 2, the thickness H of every piece of copper bar 2 is 0.5mm～1.0mm, width W is 6mm～50mm, and the width of each copper bar 2 is identical; Be coated with retardant plastic insulation layer 3 around the described copper strips 1.
The material of retardant plastic insulation layer 3 of the present invention is a flame-proof polyvinyl chloride.
The material of retardant plastic insulation layer 3 of the present invention is a low-smoke halogen-free polyolefin.
Compare with described prior art, the present invention has following beneficial effect:
1, can satisfy soft crooked and be beneficial to and lay, and not exist and wrap up in multiple insulation protection medium outside electric conductor by the anxiety of jackknifing;
2, in case chance is fiery, retardant plastic insulation layer can play and reduce flame temperature, trap heat and oxidation propagation ducts, prevents the flame continuity;
3, processing length is not restricted and is beneficial to and enhanced productivity;
4, be solidified as a whole the tight zero-clearance of overall structure by mutual knot between each copper bar;
5, the transition that can bear under the big electric current connects usefulness.
