## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a connector, and more particular to a serial advanced technology attachment (SATA) connector capable of transmitting electric power directly.
2. Description of Prior Art
Compared with a traditional parallel integrated device electronic (IDE) transmission, a serial advanced technology attachment (SATA) transmission has the advantages of a higher speed (wherein the highest speed of an ATA hard disk is approximately 133 MHz, and the highest speed of an SATA hard disk is 150 MHz or above), a smaller and more slender flat cable, a better heat dissipation, and a lower power consumption, and thus SATA hard disk has become a new-generation high-speed hard disk.
At present, a SATA disk module 10 as shown in FIG. 1 includes a second printed circuit board 20 with a side electrically coupled to a male connector (such as a 7-pin connector) of a SATA connector 30, and another side electrically coupled to a power connector 40 (such as a 2-pin connector). When the SATA disk module 10 is installed inside a casing of an electronic device, the male connector 30 (7-pin connector) of the SATA connector is connected to a female connector of a SATA connector installed on a first printed circuit board, and then a power line is inserted and connected to the power connector 40 (2-pin connector) for supplying a required electric power to the SATA disk module 10. Although connectors of this sort divide power and signal transmissions into independent connectors to provide a high sharability of the SATA disk module 10, yet the connectors also incur a complicated assembling process and a higher manufacturing cost.
To make the installation of a SATA disk module 10 easier, and lower the manufacturing cost, manufacturers generally use one of the pins of the male connector 30 of the SATA connector for transmitting electric power. However, such arrangement also causes a low sharability of the SATA disk module 10 and may even burn the SATA disk module 10 in some serious cases.
SUMMARY OF THE INVENTION
Therefore, it is an objective of the present invention to overcome the shortcomings of the prior art by providing a SATA connector capable of transmitting electric power directly, such that the SATA disk module can save the manufacture of a power connector and achieve the effects of making the manufacture of the SATA disk module much easier and lowering the cost. In the meantime, both male and female connectors of the SATA connector can be connected more securely. The invention can achieve the effects of providing a high sharability of the SATA disk module, eliminating the risk of burning the SATA disk module, improving the safety of use, and allowing manufacturers to manufacture the connectors with a minimal correction.
To achieve the foregoing objective, the present invention provides a SATA connector capable of transmitting electric power directly, comprising:
a female connector, having a body thereon, a first interface disposed at a front end of the body, and two sidewalls formed in the first interface;
two first power pins, each having an end disposed separately on two sidewalls of the first interface, and another end extended out of a rear end of the body;
a male connector, having a body disposed thereon, a side groove disposed separately on both sides of the body, an external sidewall formed at the side groove, and a notch formed on the sidewall; and
two second power pins, having an end installed onto and exposed from the notch, and another end extended out of the body;
wherein if the male and female connectors are connected, the second and first power pins will be electrically coupled to each other for transmitting electric power.
