Description

eSATA connector with power supply terminal set

Technical Field

The utility model relates to a memory connector especially relates to an extension formula serial hard disk interface connector of electrified source terminal group.

Background

At present, computer external auxiliary equipment such as a USB disk, a mobile hard disk or an external CD-ROM and the like are connected with a computer through interfaces such as USB, IEEE1394 and the like. At present, the most popular transmission interface is USB2.0, and almost all external and auxiliary devices of the computer are configured with USB 2.0. However, the upper limit of the interface transmission speed of USB2.0 is 480Mbps, which has been unable to meet the requirement of high-speed data transmission of the current external auxiliary device.

A new and faster interface mode SATA is now in force. The SATA is called totally serial advanced Technology Attachment, and is a hard disk interface specification commonly proposed by Intel, IBM, Dell, APT, major, and Seagate companies, and can increase the interface transmission speed to 3Gbps and greatly increase the transmission efficiency. However, the SATA interface has a signal terminal set and a power terminal set for data transmission, and a circuit layout is provided on the computer motherboard in cooperation with the power terminal set. The combined design of the signal terminal seat and the power terminal group causes the volume of the SATA connector to be overlarge, occupies most space positions on the circuit board, and cannot meet the design requirements of lightness, thinness, shortness and shortness of a notebook computer and a computer host.

Therefore, another new interface type eSATA (External Serial ATA) is created, which is transferred to the edge interface aggregation area of the motherboard and is only provided with a signal terminal set for data transmission, but cannot provide the required power supply after the External storage device is plugged in, and the External storage device needs to provide an additional power supply, so that the eSATA connector still has the defect of being not used. Therefore, the technicians in the industry make the following partial improvements to the defects of the eSATA connector:

fig. 7 is a perspective view of a conventional connector, which is a side-by-side connector module having both an eSATA interface and a DC power socket, according to taiwan application No. 095210905.

The connector is externally wrapped with a shielding shell B, an insulating seat body B1 is arranged in the connector, a hard disk interface terminal group B2 is arranged on one side of an insulating seat body B1, and a power supply terminal group B3 is arranged on one side adjacent to the hard disk interface terminal group B2. After the connector is used by an external storage device, data transmission is realized by the hard disk interface terminal group B2 and the power supply terminal group B3, and power supply required by the external storage device is provided.

Fig. 9 is a perspective view of another conventional connector, which is a "stacked connector module having both eSATA interface and DC power socket" of taiwan application No. 095210901. The connector is externally wrapped by a shielding shell C, an insulating seat body C1 is arranged in the connector, a hard disk interface terminal group C2 is arranged at the bottom of the insulating seat body C1, and a power supply terminal group C3 is stacked on the upper part of the hard disk interface terminal group C2. After the connector is used by an external storage device, data transmission is realized by the hard disk interface terminal group C2 and the power supply terminal group C3, and power supply required by the external storage device is provided.

Fig. 10 is a perspective view of another conventional stacked dual-transmission interface connector module of taiwan application No. 095210904. The connector is externally wrapped with a shielding shell D, an insulating seat D1 is arranged in the connector, a hard disk interface terminal group D2 is arranged at the bottom of the insulating seat D1, and a USB power terminal group D3 capable of providing power is stacked on the upper portion of the hard disk interface terminal group D2. After the connector is used by an external storage device, data transmission is realized by the hard disk interface terminal group D2 and the power supply terminal group D3, and power supply required by the external storage device is provided.

Fig. 11 is a perspective view of another conventional connector, which is a "connector receptacle adaptable to different specifications" of taiwan application No. 096204839. The connector is externally wrapped with a shielding shell E, an insulating seat body E1 is arranged in the connector, a hard disk interface terminal group E2 is arranged at the bottom of the insulating seat body E1, and a USB power supply terminal group E3 capable of providing power supply is stacked on the upper part of the hard disk interface terminal group E2. After the connector is used by an external storage device, data transmission is realized by the hard disk interface terminal group E2 and the power supply terminal group E3, and power supply required by the external storage device is provided.

In the above-mentioned various conventional connectors, since the connector portion with the power terminal set is disposed outside the standardized serial hard disk interface terminal set, the volume of the connector socket is nearly doubled. Therefore, when the circuit board is assembled on the circuit board of the notebook computer or the computer host, a larger board space is still occupied and wasted, so that the circuit board with limited specification is contrary to the design requirements of pen and computer notebook computer host for being light, thin, short and small
