Abstract
The utility model belongs to the technical field of wires and cables and particularly relates to a USB (Universal Serial Bus) cable. The USB cable comprises a line set, wherein the line set comprises a signal transmission stranded wire, two first conductors wrapped with insulators and woven fillers among the signal transmission stranded wire and the first conductors wrapped with the insulators, an aluminum foil, a winding layer, a braid and a coating are sequentially wrapped on the outer side of the line set from inside to outside, an earth wire is buried between the aluminum foil and the winding layer, and the first conductor is twisted by a plurality strand of conductor baked wires. According to the USB cable provided by the utility model, the conductor twisted by the plurality strand of conductor baked wires is adopted to replace a traditional thick conductor so as to increase the flexibility of the whole cable, improve the bending resistance of the cable and prolong the service life of the cable.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, relates in particular to a kind of USB cable.
Background technology
Now a lot of intellectualities, computerized Medical Devices, particularly the equipment such as portable monitoring, electrocardio, blood pressure measurement all needs to carry out the high-speed transmission of data, high data storage and data acquisition frequently, because universal serial port bus (Universal Serial Bus is called for short USB) has many advantages such as transmission speed is fast, reliability is high, be easy to connect, hot-swappable and is widely used.Although USB has advantages of more, but because user need to pull, bend USB cable continually, because require the cable between USB two-port must there is higher bending resistance folding endurance, and conductor in USB cable of the prior art is thicker, do not there is good pliability, and the insulator in conductor outside does not have bending resistance folding endurance conventionally yet, therefore causes the bending number of times of USB cable just may scrap 2000 left and right.Therefore, be badly in need of providing a kind of USB cable that can overcome the defect of above-mentioned USB cable.
Utility model content
(1) technical problem that will solve
The purpose of this utility model is to provide the USB cable of a kind of high bending resistance folding endurance, long service life.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of USB cable, comprise line group, described line group comprises a signal transmission twisted wire, two the first conductors that are enclosed with insulator, and described signal transmission twisted wire and described in be enclosed with the braiding filler between the conductor of insulator, outside in described line group is wrapped up aluminium foil, winding layer, braid and outer quilt from inside to outside successively, between described aluminium foil and described winding layer, be embedded with ground wire, described the first conductor is formed by multiply conductor bare wire twisted.
Wherein, described signal transmission twisted wire, by two stranded formation of the second conductor that are enclosed with insulator, is enclosed with aluminum foil mylar belt in described the second stranded conductor outside, and described the second conductor is formed by multiply conductor bare wire twisted.
Wherein, the insulator of described the first conductor outside is made by polypropylene or extra large emerald green material.
Wherein, the insulator of described the second conductor outside is made by polypropylene or extra large emerald green material.
Wherein, described braiding filler adopts anti-elater.
(3) beneficial effect
The USB cable that technique scheme provides, replaces traditional thick conductor by the conductor that adopts multiply conductor bare wire twisted to form, and to increase the pliability of whole cable, improves the bending resistance folding endurance of cable, extends its useful life.In addition, the insulator in conductor outside adopts polypropylene or extra large emerald green material, to improve the bending resistance folding endurance of this cable.In addition, braiding filler adopts anti-elater, to increase the soft and moist property of whole USB cable.The bending number of times of the USB cable that by experiment, technique scheme provides can reach 32000 times.
Accompanying drawing explanation
Fig. 1 is the structural representation of a preferred embodiment of USB cable of the present utility model.
In figure, the outer quilt of 1-; 2-winding layer; 3-weaves filler; 4-aluminium foil; 5-insulator; 6-the first conductor; 7-ground wire; 8-braid.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
Figure 1 shows that a preferred embodiment of USB cable of the present utility model.As shown in Figure 1, according to this embodiment, this USB cable comprises serving 1, braid 8 and line group.Line group comprises signal transmission twisted wire, two the first conductors 6 that are enclosed with insulator 5, and at signal transmission twisted wire be enclosed with the braiding filler 3 between the first conductor 6 of insulator 5.This braiding filler 3 is made by anti-elater.Particularly, signal transmission twisted wire, by two stranded formation of the second conductor that are enclosed with insulator, is enclosed with aluminum foil mylar belt in the outside of signal transmission twisted wire.Aluminium foil 4 is wrapped up in the outside of online group successively, the winding layer 2 of being made by tin-coated copper, the braid 8 of being made by anti-elater and serving 1, between aluminium foil 4 and winding layer 2, is embedded with ground wire 7.In order to improve the bend resistance performance of USB cable, the conductor bare wire twisted that this first conductor 6 is 0.08 ± 0.008mm by 45 strands of diameters forms.In addition, the insulator 5 of the first conductor 6 outsides adopts polypropylene or extra large emerald green material.
Further, the conductor bare wire twisted that the second conductor in signal transmission twisted wire is also 0.08 ± 0.008mm by 45 strands of diameters forms.And the insulator of the second conductor outside also adopts polypropylene or extra large emerald green material, to improve the bend resistance performance of USB cable.
Above execution mode is only for illustrating the utility model, and be not limitation of the utility model, the those of ordinary skill in relevant technologies field, in the situation that not departing from spirit and scope of the present utility model, can also make a variety of changes and modification, for example, form quantity and the diameter of the first conductor bare wire of the first conductor.Therefore all technical schemes that are equal to also belong to protection category of the present utility model.
