Description
Technical field
The present invention relates to a kind of OTG lines based on Type-C interface, set suitable for all intelligence with Type-C interface
It is standby.
Background technique
As shown in Figure 1, the OTG line of existing Type-C interface include the corresponding pin end plug interconnected and
The end receptacle, the end plug is for being inserted into main equipment, and the end receptacle is for being inserted into from equipment.In USB Type-C specification
A pull down resistor R (5.1kohm ± 20%) need to be connect by defining the CC pin in the OTG line of existing Type-C interface.When OTG line
The end plug be inserted into main equipment after, main equipment end, which detects, can enter main equipment mode after CC pin has pull down resistor, even if
The end receptacle of OTG line there is no from equipment be inserted into, the VBUS pin at the end plug also have power supply export to
The end receptacle.Its shortcoming is that: 1) will increase the power consumption of main equipment；2) there is the case where power supply output at the end receptacle
Under, it is inserted into from equipment, the risk for having short circuit from equipment can be made.
Summary of the invention
The purpose of the present invention is: after main equipment is correctly inserted into the end plug of OTG line, only have at the end receptacle from equipment
In the case where insertion, the VBUS pin at the end plug can generate power supply output.
In order to achieve the above object, the technical solution of the present invention is to provide a kind of OTG line of Type-C interface, including it is right
Answer the pin end plug interconnected and the end receptacle, which is characterized in that further include:
The CC pin of hanging detection pin set on the end receptacle, the end plug is communicated with detection pin circuitry；
Set on the grounding parts of the alterable state at the end receptacle, the state of grounding parts is between state one and state two
Variation, if the end receptacle is had no way of, equipment is inserted into, and grounding parts are in state one, detect pin floating at this time, if
The end receptacle, which has from equipment, to be inserted in place, then grounding parts are changed to state two by state one, detects pin at this time via connecing
Ground portion ground connection.
Preferably, the CC pin is connected by resistance with the detection pin.
Preferably, the grounding parts include the protrusion set on the earth shield metal frame side at the end receptacle
Elastic slice, if the end receptacle is had no way of, equipment is inserted into, and elastic slice do not contact with the detection pin, when the end receptacle has from setting
It is standby to be inserted in place, contact elastic slice with detection pin from the elastic slice of equipment pressing protrusion, detection pin is grounded by elastic slice.
Compared with existing OTG line, therefore the present invention is by adopting the above-described technical solution, have the following characteristics that
1) power consumption for avoiding OTG line from only having in the case of main equipment is only inserted increases.
2) short-circuit risks when being inserted into from equipment are avoided.
Detailed description of the invention
Fig. 1 is the connection schematic diagram of the OTG line of existing Type-C interface；
Fig. 2 is the connection schematic diagram of the OTG line of Type-C interface provided by the invention；
Fig. 3 is work flow diagram of the invention.
Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
As shown in Fig. 2, a kind of OTG line of Type-C interface provided by the invention includes corresponding pin plug interconnected
End and the end receptacle, the base of pin and the existing end plug and the end receptacle on the end plug and the end receptacle
This is identical.For the existing end plug and the end receptacle, of the invention is theed improvement is that:
1) increase hanging detection foot 1 on the end side receptacle side, meanwhile, the earth shield gold at the end receptacle
Belong to the elastic slice 2 that frame side increases protrusion.
When have be inserted into the end receptacle from equipment when, from the elastic slice 2 of equipment push projection make its with detection pin 1 connect
Touching, detection pin 1 are grounded and with the contact of elastic slice 2.When not being inserted into from equipment, elastic slice 2 does not connect with detection pin 1
Touching, detection pin 1 are hanging.
2) the CC foot at the end plug is connected by resistance R with detection pin 1.When having, when being inserted into from equipment, detection pin 1 passes through
Elastic slice 2 is grounded, so that the CC pin at the end plug is grounded by resistance R, main equipment end detects that CC pin has pull down resistor laggard
Equipment mode is become owner of, gives the end receptacle by the VBUS pin out-put supply at the end plug.When being not inserted into from equipment, inspection
It is hanging to survey pin 1, so that the CC pin at the end plug is equally hanging, at this moment the VBUS pin at the end plug does not have power supply output.
Claims (3)
1. a kind of OTG line of Type-C interface, including the corresponding pin end plug interconnected and the end receptacle, feature
It is, further includes:
The CC pin of hanging detection pin set on the end receptacle, the end plug is communicated with detection pin circuitry；
Set on the grounding parts of the alterable state at the end receptacle, the state of grounding parts becomes between state one and state two
Change, if the end receptacle is had no way of, equipment is inserted into, and grounding parts are in state one, detect pin floating at this time, if
The end receptacle, which has from equipment, to be inserted in place, then grounding parts are changed to state two by state one, detects pin at this time via connecing
Ground portion ground connection.
