Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of TYPE C interface patchcord of the utility model, including TYPE C interface 1, TYPE C interface
1 is electrically connected at least two communication connectors, and there are two preferably communication connector is set in present embodiment, the communication of two communication connectors is assisted
View is different.Wherein, two communication connectors one is USB joint 2, and one is TYPE C adapter 3.The patchcord is connected to mobile phone
After upper, USB joint 2 can be used to charge mobile phone, it is possible to use TYPE C adapter 3 connects earphone and listens song.
As shown in Fig. 2, being equipped with changer 4 between TYPE C interface 1 and USB joint 2 and TYPE C adapter 3.Switching
It is set on switch 4 there are three the power port being shorted, three power ports are electrically connected TYPE C interface, USB joint and TYPE
The power pin VBUS of C adapter.It is additionally provided on changer 4 and switchs enable pin EN and three groups of data transmission ports, three groups
Data transmission port is electrically connected the data transmission pin of TYPEC interface 1, USB joint 2 and TYPE C adapter 3.Switching is opened
Close the data transmission pin and USB joint 2 and the data of TYPE C adapter 3 biography that 4 can individually connect TYPE C interface 1
Defeated pin, and when switching enable pin EN is high level, the data of TYPE C interface 1 are transmitted pin and USB by changer 4
The data transmission pin conducting of connector 2；When beginning enable pin EN is low level, changer 4 is by the data of TYPE C interface 1
Transmission pin is connected with the data of TYPE C adapter 3 transmission pin.Preferred changer 4 is switch core in present embodiment
Piece, power port and data transmission port are the power pin being arranged on switch chip and data transfer tube foot.Wherein, it transfers
Switch 4 is analog switch.
As shown in Fig. 2, the data transmission pin on TYPE C interface 1, USB joint 2 and TYPE C adapter 3 includes just
Data transmit pin D+ and negative data and transmit pin D-, three groups of data transmission pin of changer 4 be respectively IN1, IN2,
Three groups of data transmission pin of NO1, NO2, NC1 and NC2, changer 4 include positive and negative two pins.Wherein data are transmitted
Pin IN1, NO1 and NC1 are correction data transfer tube foot, and it is negative data transfer tube foot that data, which transmit pin IN2, NO2 and NC2,.
