Description

The SATA connector

[technical field]

The present invention relates to a kind of SATA connector, particularly have a SATA connector that data-interface and power interface is incorporated into one about a kind of.

[background technology]

At present, most computers all has a hard disk storage devices.Hard disk is to be connected with computer by interface such as control card, cable and software protocol.Integrated device electronics (Integrated Drive E1ectronics, call IDE in the following text) interface is present employed a kind of hard-disk interface, this interface is a kind of advanced technology attachment (Advanced Technology Attachment, call ATA in the following text) interface, concerning the IDE standard, ATA is that existing interface is described.Present IDE/ATA standard is a kind of parallel interface, and it is in each transmission course, and long numeric data can once transmit by this interface simultaneously.Though parallel interface has bigger transmission quantity, along with the raising of transmission frequency, signal interference problem can often occur in the parallel interface transmission.

Serial advanced technology attachment (Serial Advanced Technology Attachment, call SATA in the following text) be a kind of interface specification, what they were different with parallel interface is, it only transmits a bit at every turn in transmission, like this, SATA can higher rate transmit, and the signal interference problem that occurs in high-speed transfer as parallel interface but can not occur.Along with the lifting of computer processor disposal ability, the speed of hard drive read/write data also has corresponding lifting.SATA promptly is with solving the shortcoming that appears in the Parallel ATA interface.

Cooperate existing SATA interface interface connector that SATA data connector and power connector are arranged at present, but existing SATA data connector and power connector are to separate independent setting on circuit board, meaning promptly has two attachment unit interface at least on circuit board, this just makes the user must carry two connector and cables thereof that meet data connector and power connector standard respectively, if the user leaves behind one of them, then just can't finish the transmission of installation, realization data, make troubles for user's installation, use.In addition, this existing separately independent data-interface and power interface that is provided with has occupied the bigger space of computer.

[summary of the invention]

For solving part of data-interface in the above-mentioned existing SATA connector and power interface partly is that bringing to the user of being arranged of branch carried inconvenience, also occupied the problem in the bigger space of computer simultaneously, main purpose of the present invention is to provide a kind of SATA connector, its have carry, easy for installation, compact conformation, space-saving characteristics.

SATA connector plug of the present invention, comprise body and the portion of terminal and the cable portion that extend out respectively at the body two ends, portion of terminal comprises terminal supporting part and a plurality of terminal, described cable portion comprises the cable that is electrical connected with terminal, described terminal comprises data terminal and power supply terminal, both electrical isolation, and be distributed on the same terminal supporting part, described terminal supporting part is an insulating body, insulating body surrounds a spatial accommodation, described data terminal is positioned at the upper side of the outer wall of insulating body, and described power supply terminal is positioned at the downside of the inwall of insulating body.
