A SATA data connector is provided, which is with a power supply circuit. Accordingly, the SATA data connector comprises a male data connector and a female data connector. The male data connector is with a male signal interface that has seven male data connection pins, wherein the male data connection pins consist of four data pins, a power supplying pin, and two ground pins, wherein the power supplying pin connects with a power line of a circuit board. Corresponding to the male data connector, the female data connector is with a female signal interface that has seven female data connection pins as well, wherein the female data connection pins consist of four data pins, a power receiving pin, and two ground pins. While the female data connector is connecting to the male data connector, the power receiving pin is going to contact the power supplying pin, and an operating power can be supplied from the power line of the circuit board to an applied device connected with the female data connector via the power supplying pin of the male data connector, such that the SATA data connector can work without an external SATA power cable, and the amount and volume of the cable can be reduced.

A vacuum suction apparatus includes a cup body, an adjust member, and a seal assembly. Therein, the cup body is hollowed with two penetrable ends, having a neck portion disposed with penetrable first and second openings at both ends thereof, while the first opening is combined with a joining member. The adjust member is screwed to the joining member. The seal assembly has an upper partition, a lower partition, and a membrane, cooperating with the adjust member to allow the air to pass through the upper partition, the lower partition, and the adjust member. A negative pressure is produced due to the seal function of the membrane, such that a male genital organ reciprocates to feel the force of withdrawing and pushing. The forces are adjustable with the adjust member, and the user is able to control the speed of the apparatus reciprocation.

There is disclosed a data connection device, particularly to a SATA data connection device with raised plug-in stability and reliability. The SATA data connection device mainly comprises a SATA data connection seat and a SATA component terminal. A seat body of the SATA data connection seat is provided therein with a slot. On each of two short perimeters of the seat body, there is additionally provided a laterally extending support frame having a snap-fit groove. Moreover, a shell layer of the SATA component terminal is additionally provided at the lower edge of each of two short perimeters thereof with a snap fitting. A snap hook, which may be pressed to tilt, is provided at the bottom end of the snap fitting. When a SATA data connector of the SATA component terminal is insertedly connected into the slot of the SATA data connection seat, the snap hook of the snap fitting may be also snapped into the snap-fit groove. Thus, not only the plug-in stability and reliability of the data connection device may be enhanced significantly, but also the accuracy of high-speed data transmission may be assured.

A modified standard SATA data connector is provided with a power supply circuit. The connector includes male and female data connectors. A male signal interface has seven male data connection pins, consisting of four data, a power supply, and two ground pins, the power supply pin replacing one of three original ground pins and connecting with a power line of a circuit board. A corresponding female signal interface has seven female data connection pins consisting of four data, a power receiving, and two ground pins. While the female and male data connectors are engaged, power can be supplied from the power line of the circuit board to an applied device connected with the female data connector via the power supplying and receiving pins. Thus, the SATA data connector can work without an external SATA power cable, and the volume of the cable can be reduced.
