Description

Mobile hard disk cable

Technical Field

The utility model relates to a remove storage technology field, especially relate to a mobile hard disk cable.

Background

With the development of science and technology and social economy, the progress of science and technology is affecting social economy and changing the life style of people. The mobile hard disk is convenient for users to migrate and use data. At present, the mobile hard disk is connected with the system through the interface, so the interface determines the performance and data transmission speed of the connection with the system. The interface of the current mobile hard disk connected with the external device is mainly a USB interface or an eSATA interface, wherein the USB interface is called universal serial bus (universal serial bus), can be connected with 127 peripheral devices at most, and supports hot plug and play; the highest data transmission rate of the USB1.1 is 12Mbps, and the USB2.0 is improved to 480 Mbps; the USB can provide the highest 5V and 500mA electric power for the equipment through the connecting wire, and the speed of the USB3.0 is increased to 5 Gbps; the eSATA interface is called as ExtemaleSerialATA (external Serial ATA), is an external expansion specification of the SATA interface, and has the transmission speed completely same as that of SATA; in other words, eSATA is an "external" version of SATA that is used to connect external, rather than internal, SATA devices; the eSATA can provide 3000Mb/s data transmission speed at most, which is much higher than USB2.0 and IEEE1394, and still maintain convenient hot-plug function, so that a user can connect or remove the SATA device at any time without powering off, thereby being very convenient.

Compared with the SATA interface, the eSATA changes the interface mode, but the underlying physical specification of the eSATA does not change, and the eSATA still adopts the arrangement of 7 data terminals and has no power terminal; therefore, although eSATA has the advantage of transmission speed, it lacks an effective power supply, and a mobile hard disk adopting a single eSATA interface can be normally used only by supplying power from an external power line. Therefore, an eSATA interface having power terminals is proposed, which adds two power terminals to the original one, so that the problem of power supply can be solved. Further, there is a USB/eSATA two-in-one interface on the market, in which eSATA and USB terminals are vertically provided in the same connector housing, and a plurality of connection methods including eSATA + USB or eSATAlUSB include 11 terminals, 7 of which are data terminals corresponding to the eSATA interface, and 4 of which are 2 data terminals and 2 power terminals corresponding to the USB interface. In addition, data transmission between the portable hard disk and the computer is realized through a cable, and therefore, it is necessary to provide a portable hard disk cable which is convenient to use.

To this end, chinese patent 2009201297965 discloses a mobile hard disk cable, which includes: the USB/eSATA two-in-one interface is characterized in that an eSATA terminal and a USB terminal are arranged on the inner wall of an interface body; the eSATA interface comprises an eSATA interface body, wherein an eSATA terminal and a power supply terminal are arranged on the inner wall of the interface body; a USB interface provided with a USB terminal; and one end of the transmission cable is connected with the electrical USB/eSATA two-in-one interface, and the other end of the transmission cable is electrically connected with the eSATA interface and the USB interface, so that the USB/eSATA two-in-one interface is electrically connected with the SATA terminal of the eSATA interface, the USB/eSATA two-in-one interface is electrically connected with the USB terminal of the USB interface, and a power terminal in the USB terminal of the USB/eSATA three-in-one interface is electrically connected with a power terminal of the eSATA interface. The mobile hard disk cable is electrically connected with a mobile hard disk with a USB/eSATA two-in-one docking interface, then can be used for data transmission with a computer with the USB or eSATA docking interface, and supplies power to the mobile hard disk through a power supply terminal of the eSATA interface or a power supply terminal of the USB, so that a power supply does not need to be additionally configured for the mobile hard disk, and the mobile hard disk cable is simple in structure and convenient to use.

However, the end of the cable of the mobile hard disk easily falls off from the USB/eSATA two-in-one interface, the eSATA interface, and the interface body of the USB interface due to the bending of the foldable stool during use, which exposes the cable at the connection between the cable and the interface body, and further damages the core wire in the cable, which affects the normal use of the mobile hard disk.
