DETAILED DESCRIPTION

Referring to FIG. 2, a three-dimensional diagram of a preferred embodiment of the present invention regarding to a SATA data connector is showed. A SATA data connector comprises a male data connector 21 and a female data connector 22, wherein the male data connector 21 set in a computer system, a motherboard, or a circuit board 20 has a male signal interface 211 that comprises a plurality of male connection pins 212. In accordance with the male data connector 21, the female data connector 22 has a female signal interface 211 that comprises a plurality of female pins 222, and the female connection pin 222 can be electrically connected with the female connection pin 221, since the female data connector 22 connects with the male data connector 21.

In general, the SATA data connector has seven pins, as shown at 212 and 222 of the FIG. 2, wherein the first pin (2121, S1), the fourth pin (2122, S4), and seventh pin (2123, S7) are ground pins, and other pins (2142, S2, S3, S5, S6) are data pins (A+/A−/B+/B−). In the present invention, one of S1, S4, or S7 within the male connection pin 212 can be defined a power supplying pin for supplying the operating power, such as the power supplying pin 2121 (S1) is the power supplying pin in the embodiment. Besides, one of the ground pins (S1, S4, or S7) within the female connection pin 222 can be defined a power receiving pin 2221 that corresponds to the position of the power supplying pin 2121 within the male connection pin 212.

As the male signal interface 211 connects with the female signal interface 221, the power supplying pin 2121/power receiving pin 2221, ground pin 2122,2123/2222,2223, and data pin 2124/2224 can respectively connect each other. Due to the male data connector 21 is set on the circuit board 20, the power supplying pin 2121 of the male data connector 21 is electrically connected with a power line 205 of the circuit board 20. Therefore, the power line 205 of the circuit board 20, the power supplying pin 2121 and the power receiving pin 2221 can form a power supply circuit to supply the operating power to the female data connector 22. The female data connector 22 can work without the external SATA power cable, and the volume and the amount of the SATA power cable can be decreased.

The conventional female data connector (22) of SATA data connector doesn't have the power receiving pin (2221), and a ground pin is used to replace the power receiving pin (2221) is. Once a conventional female data connector (22) connects to the male data connector 21 with power supplying pin 2121, the SATA data connector may be damaged. Thus, a protective device 213 set on the circuit board 20 is used to connect between the power supplying pin 2121 of the male data connector 21 and the power line 205 for protecting the SATA device and the external device, since the operating power can't transmit to which via the power supplying pin 2121. In another word, as the conventional SATA female data connector (22) connects with the male data connector 21 of the invention, the protective device 213 can break the power supply circuit, such that the conventional SATA female data connector (22) can work regularly.

The protective device 213 can be an automatic resettable fuse, a diode, a switch device, such as a relay, or a circuit breaker to form a broken circuit, and the conventional SATA female data connector (22) can work regularly.

The efficacy of above mentioned broken circuit can be described as follows, for example, the power supplying pin 2121 can't supply power to the connection pin (2221), while the conventional SATA female data connector (22) connects to the male data connector 21 of the invention, since the protective device 213 is an automatic resettable fuse. At this time, the automatic resettable fuse 213 has to overload and trip, and the conventional SATA female data connector (22) can work normally. Once the female data connector (22) is removed from the male data connector 21, the automatic resettable fuse 213 can connect with the power supplying pin 2121 again, and the theory thereof is according to the usual fuse for protecting the extended line. Of course, the other device or circuit that can form a broken circuit can be used in the present invention.

In another embodiment of the present invention, the protective device 225 can be set within the female data connector 22 to connect with the power receiving pin 2221. As the female data connector 22 with the power receiving pin 2221 connects to the conventional male data connector (21) without the power supplying pin 2121, the operating power can't transmit to the computer system or the circuit board 20 via the power receiving pin 2221 of the female data connector 22 and the ground pin 2121 of the male data connector (21) due to the protective device 225, so the protective device 225 can protect the female data connector 22, male data connector (21), or the circuit board.

The female data connector 22 can connect with an external device 24 or an applied device 223, 2235 via a transmission line 23, wherein the applied device 223 or 2235 can be a memory, a control device, or a circuit board, and the transmission line 23 can comprise a power circuit and a data circuit. Besides, the protective device 225 can be set within the external device 24 or the applied device 223, 2235 to be another protective device 245.

Referring to FIG. 3, a three-dimensional diagram of another embodiment of the present invention is showed. Due to the volume of the applied device 323, such as circuit board, control device, or memory, is more and more small, the previous mentioned external device (24) or applied device (223) can be set within the female data connector 32 to be an applied device 323 within the female data connector 32. Therefore, the female data connector 32 can be a SATA applied device 32 that can be used to connect with the male data connector 21, such that the volume and amount of the cable can be reduced.

For example, as the applied device 323 is a memory, the SATA applied device 32 can be as a storage device that is similar to a flash disk. On the contrary, as the applied device 323 is a circuit board or a control device, the SATA applied device 32 can be a device within a personal computer, an industry computer, or a small electric device.

The male connection pin of the male data connector 41 can be a pin header 411 that is different from the foregoing gold finger (212). Besides, the female connection pin of the female data connector 42 can be a correlating female header 422 that is also different from the gold finger (222). As the male connector pin and the female connector pin are respectively the pin header 411 and the female header 422, the contact area between that can be wider than the gold finger (212) leading to the link thereof can be tight and stable. Therefore, as the male data connector 41 connects to the female data connector 42, the link of that can't be failure by an external force to ensure the stability and exactitude of the transmission data.

In above embodiment of the present invention, the SATA male data connector (21) has seven pins, and the power supplying pin 2121 can be one of the three ground pins of the prior art.
