In one embodiment, as shown in fig. 7, wire body 31 includes 312, two power supply core 311, wire core signal cores 313 and jacket power supply core 311, wire core 312 and signal core 313 sheath 314, sheath 314, which is adopted, to be made from an insulative material, Such as polyvinyl chloride, polyethylene, polypropylene or rubber material etc..

In some embodiments, the quantity for the signal core 313 for including in wire body 31 can also be one, three, four or Person is more, and the quantity for being suitble to signal core 313 is selected according to the speed of transmission and the signal classification of transmission.

Power supply core 311 includes the insulating lacquer layer 316 of the first wire of at least one 315 and the first wire of jacket 315, When first wire 315 is one, power supply core 311 is sub-thread core；When first wire 315 is two or more, power supply line Core 311 is multiply core, and more first wires 315 are in that twisted shape links together.

Wire core 312 includes the insulating lacquer layer 316 of the second wire of at least one 317 and the second wire of jacket 317, the When two wires 317 are one, wire core 312 is sub-thread core；When second wire 317 is two or more, wire core 312 is Multiply core, more second wires 317 are in that twisted shape links together.

Signal core 313 includes the insulating lacquer layer 316 of at least one third wire 318 and jacket third wire 318, When third wire 318 is one, signal core 313 is sub-thread core；When third wire 318 is two or more, signal wire Core 313 is multiply core, and more third wires 318 are in that twisted shape links together.

In one embodiment, the first wire 315, the second wire 317 and third wire 318 are copper wire, work as electricity When source core 311, wire core 312 and signal core 313 are sub-thread core, the first wire 315 and the second wire 317 Diameter is all larger than the diameter of third wire 318；When power supply core 311, wire core 312 and signal core 313 are multi cord When core, the first wire 315, the second wire 317 quantity be more than third wire 318 quantity.

In one embodiment, insulating lacquer layer 316 is skin of paint, the first wire 315, the second wire 317 and third gold Belong to 318 outsourcing skin of paint of silk, improve the draftability and warping resistance of wire body 31, extends the service life of data line 30.

It should be pointed out that the above-mentioned twisted concentric type that can be is twisted or divides twisted to formula.

First plug 32 is USB plug, and the second plug 33 is Mini USB plug.Certain first plug 32 and the second plug 33 can also be the plug of other common types, such as Type-C plug, Micro USB plug or Lightning plug respectively.

In one embodiment, data line 30 further includes third plug 34, and third plug 34 is Lightning plug, third Plug 34 close to the second plug 33 side be equipped with the matched left slot 35 in the end of the second plug 33, for detachably connecting Connect the second plug 33.Similarly, third plug 34 or the plug of other common types.

In one embodiment, data line 30 further includes the 4th plug 36, and the 4th plug 36 is Type-C plug, the 4th plug 36 side close to the second plug 33 be equipped with the matched right slot 37 in the end of the second plug 33, for being detachably connected the Two plugs 33.Similarly, the 4th plug 36 or the plug of other common types.

If being basic state when data line 30 is shunk in shell 10 completely, clamp 212 rests against detent 247 at this time.It draws When stretching one grade, while the first plug 32 and the second plug 33 are stretched, wire body 31 is overhanging, and core wheel 22 rotates with it, and clamp 212 is in cunning Motion path in slot 241 is as shown in figure 8, since clamp 212 has the trend of outward movment, until at notch 251, i.e., can break into Notch 251 slides into detent 247 then along extension 245, and core wheel 22 stops operating, and data line 30 stops elongation, completes one grade It stretches.

If stretching always, after core wheel 22 keeps rotation, clamp 212 then to move such as Fig. 8, into inner groove 248, in inner ring Slot 248 moves always, as shown in figure 9, until be stretched to the length (gear number >=2) of needs, then to being caught in detent at notch 251 247, core wheel 22 stops operating, and completes to stretch.If the length stretched is too long, when needing past exhausting line body 31, loosens first and insert First 32 and second plug 33, due to the automatic telescopic of elastic component 23, toward external expansion, because fixation is fixed in the inner end of elastic component 23 Column 14, outer end connect the outer wall of core wheel 22, will drive core wheel 22 when so elastic component 23 is toward external expansion and rotate, the direction of rotation with Direction of motion when stretching is on the contrary, then the motion profile of clamp 212 is transformed into rail as shown in Figure 10 from track as shown in Figure 9 Mark.

When rapid desufflation wire body 31, the first plug 32 and the second plug 33 are slightly stretched, clamp 212 is made to skid off detent 247 Into outer groove 249, elastic component 23 drives core wheel 22 to rotate, and the motion profile of clamp 212 is as shown in figure 11, until wire body 31 is complete Recycling, clamp 212 slide into detent 247 along guide surface 252, and core wheel 22 stops operating, and contraction finishes.

The utility model scalable data line 100, stretches and shrinkage operation is convenient, and the rolling not against ball drives core wheel 22 Rotation, frictional resistance is smaller, and noise is small, and stretches and shrink smooth, determine shelves using detent 247, card shelves consolidate.

Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, all should be considered as described in this specification.

A kind of embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed, But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
