Description
The present invention relates to a kind of cable manufacture method, be meant a kind of simplification fabrication schedule especially, reduce the manufacture method of the cable of man-hour and cost.
General cable is according to different signal transfer functions, has different structural designs, fluorescent screen commonly used promptly comprises several different types of electric wires with cable, as coaxial line (COAXIAL CABLE) and holding wire (shown in Figure 1A) such as (SIGNAL CABLE), wherein this coaxial line is the signal such as the tricolor signal of carry high frequency rate mostly, and the low-frequency signal of this signal wire transmits.As for existing cable line manufacture method, can be divided into following fabrication schedule by cable contained coaxial line and holding wire:
1, the manufacturing of coaxial line: at first with an extrusion molding machine at peripheral coating first insulating barrier of thick bare copper wire (as polyethylene, PE); After this first insulating barrier cooling, utilize braiding machine or reel winder again, this polyethylene layer is hedged off from the outer world fully at the screen (being generally copper cash mesh grid or copper cash twisted wire) that this first insulating barrier outer surface layer overlay is made of ground wire; Thereafter, utilize again another extrusion molding machine at this screen outer surface coating second insulating barrier (as polyvinyl chloride, PVC); After treating the cooling of this second insulating barrier, promptly finish the manufacturing (its structure can with reference to Figure 1B) of coaxial line.
2, the manufacturing of holding wire: the manufacturing of holding wire as described above coaxial line through the manufacture process of extrusion molding machine coating insulating barrier, it directly is coated on an insulating barrier (being generally polyvinyl chloride) a kind of outer surface of thin bare copper wire equally, to finish the making of this holding wire.
3, the manufacturing of cable: several completed aforementioned coaxial lines and holding wire are delivered to twisted wire board place, together be twisted into the twisted wire of a branch of bundle with the aluminium foil of band shape, wherein this aluminium foil closely is coated on the periphery of this coaxial line and holding wire.The mesh grid that is made of copper cash at the peripheral careful ground of this bunchy twisted wire layer overlay with braiding machine again is to form shielding protection to this twisted wire.The twisted wire that at last this is provided with mesh grid is delivered to the extrusion molding machine, coating the 3rd insulating barrier (as polyvinyl chloride) once more in the periphery of described twisted wire.So far, the manufacture process of this cable is finished (its structure can with reference to Figure 1A).Yet the manufacture method of aforementioned existing cable line has following shortcoming:
The winding of A, ground wire is long man-hour.As previously mentioned, this ground wire is in the peripheral careful winding of coaxial line with braiding machine or reel winder.Yet the careful degree of its winding depends on whether the feed speed of coaxial line on this braiding machine or the reel winder equals the speed of wrap of ground wire.Because when the feed speed of coaxial line equals the speed of wrap of ground wire, ground wire can be laid on the periphery of coaxial line equably, but also therefore causes the winding of ground wire long man-hour; If adopt the ground wire canoe of mesh grid, it twines man-hour will be longer.
The shaping time of B, insulating barrier is long, manufacturing cost is high and easily produce waste material.When coaxial line was done the insulating barrier coating, the shaping speed that must equal insulating barrier because of the feed speed of coaxial line can make this insulating barrier be coated on the coaxial line equably, so the shaping time of insulating barrier is very long.Secondly, the whether complete stability that often is subject to feed of the moulding of this insulating barrier, and factors more rambunctious such as the water content of the stability of feed and raw material, a material size are relevant.Even control water content, a material size of raw material in advance well, formalities such as first drying and screening before promptly raw material feeds intake, what still can produce waste material in forming process for it, and just the waste material amount can be than reduce to some extent in the past; But relatively, it has increased the process of dry and screening, and therefore manufacturing cost and cost of material can increase, and make shaping time longer.
The winding of C, ground wire adheres to different processing stations separately with the moulding of insulating barrier, because of the ground wire on the coaxial line twines is to finish at braiding board or spiral board place, the coating of insulating barrier is then finished at extrusion molding board place, both finish at different work stations respectively, can't merge and carry out, so can't reduce man-hour.
At the shortcoming of described existing cable manufacture method, main purpose of the present invention provides a kind of manufacture method of cable, and wherein ground wire is to twine coaxial line with specific lay, and the feed speed of coaxial line is increased, and shortens and twines man-hour.
Have, another object of the present invention provides a kind of manufacture method of cable again, and it replaces existing second layer insulating barrier as screen with aluminium foil, and replaces the moulding coating with winding method, saves drying and screening process.
The object of the present invention is achieved like this, a kind of cable manufacture method promptly is provided, wherein, the periphery of at least one coaxial line is to utilize coiling machinery to twine metallic shield device and ground wire, make the metallic shield device be in the internal layer of winding layer and ground wire is in skin, perhaps make the metallic shield device be in the skin of winding layer and ground wire is in internal layer.
The advantage of the inventive method is that it is made in the method for cable, and metallic shield device and ground wire, in the time of further reducing worker and are difficult for producing waste material in the inferior winding of finishing simultaneously coaxial line of same work station, reduce production costs.
Below in conjunction with accompanying drawing, embodiments of the invention are described, wherein:
