Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art's acquired every other implementation without creative efforts
Example, shall fall within the protection scope of the present invention.
The embodiment of the present invention provides a kind of USB connector and a kind of electronic equipment respectively, and Fig. 1 is USB connector and electronics
The schematic diagram of equipment connection.
As shown in Figure 1, USB connector 10 includes：
First Type-C interfaces 11, the first Type-C interfaces 11 include power pins and communications pins；And
The current divider 12 being electrically connected respectively with above-mentioned power pins and above-mentioned communications pins；
Wherein, when electronic equipment 20 is charged by USB connector 10, current divider 12 is for shunting charging current
To above-mentioned power pins and above-mentioned communications pins.
The pin of existing USB Type-C interfaces is double pin, and the distribution of main pin may refer to Fig. 2, USB
The function of the main pin of Type-C interfaces may refer to table 1.
Table 1
According to existing protocol, USB Type-C interfaces are communicated by pin D+ or pin D-, by pin VBUS into
Row power transmission, other pins are on the shelf.
In order to improve the conveyance capacity of USB connector 10, current divider is arranged in USB connector 10 in the embodiment of the present invention
12.By the way that current divider 12 to be electrically connected with the power pins of USB connector 10 and communications pins respectively, in this way, when using USB
When connector 10 charges to electronic equipment 20, charging current can be branched to the power pins of USB connector 10 by current divider 12
And communications pins.Charging current branches to the power pins and communications pins of USB connector 10, and through USB connector 10
Power pins and communications pins conduct to the Type-C interfaces of electronic equipment, to realize charging to electronic equipment 20.
In the embodiment of the present invention, current divider 12 has the communications pins (being not limited to communications pins) of control USB connector 10
The ability of current switching.A kind of embodiment is that MCU (Microcontroller Unit, microcontroller are arranged in current divider 12
Unit), the control to the communications pins current switching of USB connector 10 is realized by MCU.
From the foregoing, it will be observed that in the embodiment of the present invention, USB connector 10 is other other than power pins can be by electric current
Communications pins can also pass through electric current.Compared with the prior art, since the quantity of the pin of overcurrent increases so that USB connector
10 conveyance capacity is improved, so as to realize the high current quick charge to electronic equipment.
It should be noted that the power pins in the embodiment of the present invention refer to Fig. 1 and pin VBUS shown in Figure 2, communication
Pin may include Fig. 1 and pin D+ shown in Figure 2, pin D-, pin CC1, pin CC2, pin TX+, pin TX-, draw
It is any one or more in foot RX+, pin RX-.
Optionally, current divider 12 will fill respectively according to the power pins of USB connector 10 and the current-carrying capacity of communications pins
Electric current distributing to USB connector 10 power pins and communications pins.
Wherein, current-carrying capacity refer to conductor can continuous bearing without cause its equilibrium temperature be more than specified value maximum electricity
Stream.
In USB connector 10, the line for connecting power pins is passed through from the line of connection communication pin through possible different, and connection is different
The line warp of communications pins may also be different.Usually, connect the line of power pins through larger, the line of connection communication pin pass through compared with
It is small.It is to be appreciated that line, through bigger, corresponding current-carrying capacity is also bigger；For line through smaller, corresponding current-carrying capacity is also smaller.
In consideration of it, in embodiment of the present invention, current divider 12 can respectively according to the power pins of USB connector 10 and
Charging current is branched to the power pins and communications pins of USB connector 10 by the current-carrying capacity of communications pins.
Further, current divider 12 can draw according to the current-carrying capacity of the power pins of USB connector 10 according to the power supply
The proportional value of the current-carrying capacity of foot, controls the overcurrent of each communications pins of USB connector 10 respectively.
For example, it is assumed that the current-carrying capacity of power pins VBUS is I1, then the overcurrent of current divider control communications pins CC1 is I2=
k1×I1, the overcurrent that current divider controls communications pins D+ is I3=k2×I1, the overcurrent that current divider controls communications pins TX+ is I4=
k3×I1, etc..Wherein, k1、k2、k3Value can be determines according to actual conditions.It is more than respectively when the line of power pins VBUS passes through
The line of communications pins through when, k1、k2、k3Value be respectively less than 1.
