second terminal

31,32, thereby increased the spacing between three row's terminals, to guarantee the signal stabilization transmission.In addition, described projection 15 positions have increased the thickness of pedestal 11, thereby make insulating body 1 have enough thickness with fixing the 3rd terminal 33.

Ginseng Fig. 3, label E1 ~ E7 is a first terminal 31, and label U1 ~ U4 is second terminal 32, and label P1 ~ P3 is the 3rd terminal 33, and wherein label is that the 3rd terminal 33 of P1 is located between second terminal 32 that label is U1, U2 and is that the first terminal 31 of E2 is relative with label; Label is that the 3rd terminal 33 of P2 is located between second terminal 32 that label is U2, U3 and is that the first terminal 31 of E4 is relative with label; Label is that the 3rd terminal 33 of P3 is located between second terminal 32 that label is U3, U4 and is that the first terminal 31 of E6 is relative with label.

Ginseng Fig. 3, the first terminal 31 is the ESATA terminal, include two pairs of signal terminals and three earth terminals of meeting the ESATA specification in these seven terminals, wherein label is that E2, E3 are a pair of signal terminals, label be E5, E6 be another to signal terminal, the residue label is that E1, E4, E7 are earth terminals.Second terminal 32 is the USB terminal, includes a pair of signal terminal and a pair of dc power supply terminal that meets the USB specification in these four terminals, and wherein label is that U2, U3 are a pair of signal terminals, and label is that U1, U4 are pair of power source terminals.Definition by above-mentioned each ESATA terminal and USB terminal is learnt, ESATA terminal non-transformer terminal, have at least one to be the power supply terminal of required power supply in the time of can providing the ESATA plug to dock in the 3rd terminal 33 of the utility model electric connector with electric connector, the ESATA plug also should be provided with the cooperation power supply terminal that can contact with this power supply terminal simultaneously, thereby make the ESATA plug insert behind the butt joint space 101 of electric connector simultaneously transmission signals and power supply is provided, so can solve the existing existing problem of electric connector in the background technology.

Except that the power supply terminal that wherein must provide ESATA plug working power, other two can be other functional terminal, has below listed several execution modes in three the 3rd terminals 33:

(1) one for providing the power supply terminal of ESATA plug-in power pack, other two power supply terminals that provide the USB plug power supply.So USB plug not only can obtain above-mentioned label for the power supply that 8,11 second terminal is provided, and also can obtain by above-mentioned two the 3rd power supplys that terminal is provided.

(2) two for providing the power supply terminal of ESATA plug-in power pack, and remaining one is an earth terminal.These two power supply terminals can provide ESATA to insert first two different working power, remain one and make then that for earth terminal two power supply terminals need not to share the stable transfer that earth terminal influences signal with each signal terminal set of the first terminal 31.

(3) three are the power supply terminal that the ESATA plug is provided.These three power supply terminals can provide the ESATA plug three kinds of different working powers.

Except that above-mentioned three kinds of execution modes, the utility model also has other execution mode, enumerates no longer one by one at this.In addition, after the ESATA plug insertion butt joint space 101 that cooperates power supply terminal was not set, three the 3rd terminals did not participate in work this moment, but electric connector then needs just transmission signals of external power supply as in the background technology.
