Can the user connect the charger through the port that charges, through connecting smart machine type the plug of C interface charges to the smart machine, when charging, pegs graft the earphone on the 3.5mm interface, just can realize using the earphone when charging, has made things convenient for the user widely to the advantage that has simple structure.
Description
Technical field
This utility model is related to USB interface field, more particularly to a kind of interface switching device.
Background technology
Type-C interfaces are one kind of USB interface, and size is about 8.3mm × 2.5mm, as other interfaces supports USB
The functions such as the charging of standard, data transfer, display output.Traditional USB interface is compared, Type-C interfaces are connect for two-sided inserting
Mouthful, it is to support the two-sided insertion of USB interface, without positive and negative wrong plug problem during use, convenient user's the characteristics of which is maximum
Grafting.In addition, the largest data transfer speed of Type-C reaches the 10Gbit/ seconds, meet 3.1 standards of USB.Just because of its work(
The advantages of energy comprehensive, rational in infrastructure and fast transmission speed, Type-C interfaces are increasingly widely used on electronic product.
Many Android system mobile phones on the market are using more easily Type-C interfaces, and many mobile phone vendors commercial city is only
One Type-C interface is set on mobile phone.Smart mobile phone power consumption of today is too fast into normality, and user needs to be high energy often
The smart mobile phone of consumption charges, but a Type-C interface is only designed with mobile phone, and this will produce charging and using earphone
Conflict, user can not be charged simultaneously and using the earphone of 3.5mm plugs.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, this utility model provides a kind of interface switching device, only solves
There is the mobile phone of a Type-C interface can not be while charging and using the problem of earphone.
This utility model solve technical scheme that its technical problem adopted for：
A kind of interface switching device, including a body, one end of the body are provided with connection smart machine Type-C and connect
The plug of mouth, the other end of the body are provided with one for connecting the charging port of charger, the side of the charging port
While being additionally provided with 3.5mm interfaces, the plug is electrically connected with 3.5mm interfaces, charging port respectively.
Further, the 3.5mm interfaces are connected with body by flexible cable.
Further, the charging port is using A types USB public affairs mouth.
Further, connected by flexible cable between the charging port and body.
Further, described is provided with vivo for earth leakage protective protection location.
Further, described is provided with vivo for eliminating the anti-tampering unit of charging current noise.
The beneficial effects of the utility model have：A kind of interface switching device of this utility model, including a body, the body
One end is provided with plug, is extended after plug connects the Type-C interfaces of smart machine so that user can charge
While use earphone, there is simple structure and easy to use.
Description of the drawings
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail, wherein：
Fig. 1 is the structural representation of this utility model first embodiment；
Fig. 2 is the structural representation of this utility model second embodiment.
Specific embodiment
Referring to Fig. 1, Fig. 1 is the structural representation of this utility model first embodiment.A kind of interface conversion of this utility model
Device, including a body 1, one end of the body 1 are provided with the plug 2 of connection smart machine Type-C interfaces, the body 1
The other end be provided with one for connecting the charging port 3 of charger, the side of the charging port 3 is additionally provided with 3.5mm
Interface 4, the plug 2 are electrically connected with 3.5mm interfaces 4, charging port 3 respectively.This device is plugged on intelligence by plug 2 and sets
On standby Type-C interfaces, and the 3.5mm interfaces 4 for grafting earphone are expanded, plug 2 and 3.5mm interfaces 4 are electrically connected with.
User connects charger using charging port 3, and the plug 2 of Jing connection smart machine Type-C interfaces charges to smart machine, fills
While electric, earphone is plugged on 3.5mm interfaces 4, it is possible to realize 3.5mm earphones are used while charging, with knot
The advantages of structure is simple and easy to use.
Referring to Fig. 2, Fig. 2 is the structural representation of this utility model second embodiment, and second embodiment is first embodiment
Another kind of implementation.The 3.5mm interfaces 4 and charging port 3 are connected with body 1 by flexible cable.Using flexible electrical
Cable couples together 3.5mm interfaces 4, charging port 3 and body 1, increases the motility of this device, plays a protective role.Make
During this device, charging wire or earphone cord are possible to be subject to draw infringement again due to accident, at this moment flexible electrical
Cable can just play a good cushioning effect, protection charging wire or earphone cord.
In terms of circuit design, in the body 1, residual current protective unit is provided with, residual current protective unit includes current limliting list
Unit, can cut off circuit when current is excessive in time, protect user security.Earphone, the tonequality of earphone are used while charging
May be affected due to the interference of charging current, be provided with the body 1 for eliminating the anti-of charging current noise
Interference unit, the anti-tampering unit include audio receiver and antinoise pio chip, by reception, the frequency of Analyze noise
And the frequency contrary with noise is produced, mutually weaken or offset, reach noise reduction.
In addition, the charging port 3 is suitable for smart machines most of on the market using A types USB public affairs mouth.The charging end
Connected by flexible cable between mouth 3 and body 1, the effect of flexible cable is above explaining that here is not repeated.
The above, simply better embodiment of the present utility model, but this utility model is not limited to above-mentioned reality
Example is applied, as long as which reaches technique effect of the present utility model with any same or similar means, should all belong to of the present utility model
Protection domain.
