Preferably; Described charging jockey also comprises and is used to make the level of No. 4 pins of USB output to be defaulted as low level resistance; No. 4 pins of one end of said resistance and USB output are connected, and the other end connects No. 4 pins of input and No. 5 pins of USB output respectively.

Preferably, described resistance is 220k Ω resistance.

Preferably, described charging jockey comprises 2 above-described USB outputs.

Preferably, described charging jockey also comprises tuning fork fork ditch output, and tuning fork fork ditch output head anode end is connected with No. 1 pin of input, and No. 4 pins of negative pole end and input of tuning fork fork ditch output are connected.

Preferably, the quantity of described USB output is 2.

Described input is a USB interface.

Described USB output is the MINI USB interface.

Described USB output is the MICRO USB interface.

Compared with prior art, the charging jockey of the utility model has following useful technique effect: 1, can not cause data transmission interference; 2, the ID pin of MINI USB or MICRO USB interface is in low level, can let the mobile phone of brands such as Nokia and Motorola charge normal; 3, USB output interface is various, adapts to numerous dissimilar electronic products; 4, can be a plurality of electronic product chargings simultaneously.

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.
