Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
A kind of USB molded lines structure of the present invention, as shown in Figure 2, this USB molded lines by 1P holding wire 1,2C power line 2, woven shield 3, insulating barrier 4, outward by 5 and ground wire 6 constitute, described two pair twist 1P holding wires 1 are positioned at USB molded lines center, two 2C power line 2 symmetries be positioned at pair twist 1P signal 1 both sides, coated by 5 by woven shield 3 with outside insulating successively in their outsides, described ground wire 6 is gone back cable body insulating barrier 4 on described 1P holding wire 1 and the 2C power line 2 in woven shield 3.
The molded lines stranding pair twist aggregate device of USB molded lines of the present invention, as shown in Figure 3, it is to enter cabler at two 1P holding wires 1 and two 2C power lines 2 by pay off rack 10 to cross between the line plate 7, distance is crossed line plate 7 one segment distance places, be provided with an eye mould fixed mount 8 is installed, and pass through the line footpath behind the 1P holding wire 1 heart yearn pair twist by being slightly larger than, be provided with on eye mould fixed mount 8 a stranding eye mould 9 that is used for pair twist is installed, stranding eye mould 9 passes through line footpath 0.3～0.8 millimeter greater than line footpath behind the 1P holding wire 1 heart yearn pair twist.
The technical process of USB molded lines pair twist set stranding of the present invention is, with two 1P holding wires 1 and two 2C power lines 2 of extruder extrusion molding pass respectively in the hole of pay off rack 10 separately, and the stranding eye mould 9 that two 1P holding wires 1 are provided with via eye mould fixed mount 8 penetrated carry out pair twist, the hole, centre position that the 1P holding wire 1 of pair twist is crossed line plate 7 by cabler is pierced into then, two 2C power lines 2 are pierced into by crossing line plate 7 laterally zygomorphic two holes, carry out the set of wire rod molded lines together; Carry out braid shielded and finished product extrusion stranding operation again after the pair twist set.
In order to process stranding USB molded lines of the present invention structure cable, the cabling process flow process of this USB molded lines structure is followed successively by: the extrusion of A-heart yearn, the set of B-pair twist, C-braid shielded, the extrusion of D-finished product.
According to the cable technological process, A-heart yearn extrusion operation respectively behind two white green 1P holding wires 1 of extrusion and two the dark red 2C power lines 2, according to setting required lay of cable and selected polymeric barrier layer materials, is adjusted pair twist aggregate device parameter by conventional cable production line; Adopt the molded lines stranding pair twist aggregate device that aims at the stranding setting in B-pair twist set operation, entering cabler at two 1P holding wires 1 and two 2C power lines 2 by pay off rack 10 crosses between the line plate 7, distance is crossed line plate 7 about 10～15 centimeters, be provided with eye mould fixed mount 8 is installed, and on eye mould fixed mount 8, be provided with and install one in the line footpath greater than 0.3～0.8 millimeter stranding eye mould 9 that is used for pair twist in twisted pair wire footpath by being slightly larger than passing through behind the 1P holding wire 1 heart yearn pair twist; To be wound on respectively on the cable volume 11 by two 1P holding wires 1 and two 2C power lines 2 of extruder extrusion molding are emitted separately, in the hole of pay off rack 10, pass respectively, and two 1P holding wires 1 are penetrated via the stranding eye mould 9 of eye mould fixed mount 8 carry out pair twist, the hole, centre position that the 1P holding wire 1 of pair twist is crossed line plate 7 by cabler is pierced into then, two 2C power lines 2 are pierced into by crossing line plate 7 laterally zygomorphic two holes, carry out the set of wire rod molded lines together; Carry out C-braid shielded operation and D-finished product extrusion operation again after the pair twist set, promptly carry out the USB molded lines woven shield 3 braiding and outward by 5 coatings, finally finish USB cable 12 strandings.
USB molded lines wire rod structure of the present invention is provided with rationally, helps the stability of signal wire transmits, and the symmetric arrangement of 1P holding wire and 2C power line not only makes this body structure of wire rod obtain effective protection, and the wire rod outward appearance of pair twist set also is greatly improved.Adopt stranding pair twist aggregate device once to finish pair twist set technology, reduced the number of the operation that wire rod is made, also reduced the destruction to wire rod structure relatively, the wire rod structure performance data index of stranding meets the design performance requirement fully.
With U.S. rule 30AWG/1P+30AWG/2C USB wire rod is example, with its line of traditional handicraft directly behind stranding minimum be 2.8～-3.2mm; And after adopting molded lines structural requirement cabling process of the present invention, because the stranding eye mould that is provided with during stranding is well realized 4 heart yearn structure arranged layouts, thereby is made the wire rod external diameter of the product of finishing can accomplish 2.4mm., dwindle the line footpath, also saved wide variety of materials.
The wire rod electric property that the wire rod pair twist mainly influences, wherein characteristic impedance is the most direct, adopt above-mentioned technology after, its characteristic impedance does not have the variation of essence, and is as shown in the table:
Table one parameter: TDR-postpones the difference unit: the ns/M requirement result: by
| Line style | Logarithm | The standard maximum specification | The standard minimum gauge | Postpone difference data | The result |
| The |
1 pair | 5.2 | ------- | 4.785 | By |
