Embodiment
To combine accompanying drawing and embodiment that the utility model is further specified below.
As shown in Figure 1, the described a kind of charging jockey of the utility model comprises 1,2 USB outputs 2 of input and tuning fork fork ditch output 3.
As shown in Figure 2; The utility model uses USB interface as input 1, and said input 1 comprises 4 pins, is respectively: as No. 1 pin 11 of input of VCC end; Be used to transmit No. 2 pins of input 12 and No. 3 pins 13 of input of data, as No. 4 pins 14 of input of GND end.
Like Fig. 3 and shown in Figure 4; The charging jockey of the utility model uses MINI USB interface 201 and MICRO USB interface 202 as USB output 2; Said USB output 2 comprises 5 pins, is respectively: as No. 1 pin 21 of USB output of VCC end, be used to transmit No. 2 pins of USB output 22 and No. 3 pins 23 of USB output of data; Be used to judge No. 4 pins 24 of USB output of ID, as No. 5 pins 25 of USB output of GND end.
Please with reference to Fig. 5, said tuning fork fork ditch output is adopted international standards, and tuning fork fork ditch output head anode end 31 is connected with No. 1 pin 11 of input, and No. 4 pins 14 of negative pole end 32 and input of tuning fork fork ditch output are connected.
