an electrical connector

technical field

The utility model relates to the field of electric connection, in particular to an electric connector.

Background technique

With the advancement of the technology era and the development and prevalence of computer technology, more and more functions and additional functions are provided for users to use conveniently, and relatively make users' desire for performance stronger. Manufacturing from various manufacturers It can be seen that the clock pulse of the processor and memory is constantly increasing, and the speed of the hard disk and optical disk is advancing with the times. Therefore, the emergence of new specifications and new technologies in almost every electronic technology product is to solve the problem of transmission speed. In 2000, six companies including APT, Dell, Intel, IBM, Quantum (now acquired by Maxtor) and Seagate jointly formed the Serial ATA working group (Working Group), and then with the increase of organization members , also officially changed its name to SATA IO (Serial ATA International Organization) in 2004. At present, as long as the drafting, discussion or promotion work related to the SerialATA standard is carried out, it is promoted by this organization.

As for the working principle of SATA (Serial ATA), as the name suggests, it is expected to be the successor of Parallel ATA, so the price should not be too expensive, and it is pre-set that the software such as the operating system can be 100% compatible, so as to avoid previous problems. It is expected that IEEE 1394 will replace PATA and fail. SATA basically uses point-to-point transmission and Fiber Channel interface coding. Compared with the old PATA 40 signal lines in the signal line part, it can be said that It has been simplified a lot. There are only two sets of differential signal wires (4 in total), plus 3 ground wires, and there are only 7 wires in total. With the ratio of 7 to 40, the wires can be so simplified The design is helpful to a certain extent for the use of the internal space of the chassis, and SATA has the characteristics of LVDS low-voltage anti-interference, which not only has a better solution to noise and power loss, but also avoids PATA controllers. The limitations of the inability to use more advanced and cheaper manufacturing processes; but because the SATA connector cannot directly supply power when in use, an additional power connector must be provided to provide the power required for the use of the SATA connector, which also causes the SATA connector to be used. Many deficiencies, such as:

(1) The currently used SATA connectors must be equipped with a power connector, which must be plugged in at the same time to transmit data. Otherwise, the data cannot be transmitted, which is inconvenient to use.

(2) On the circuit board where the SATA connector is installed, the power connector must be installed again, which will also occupy the space on the circuit board and affect the circuit layout of the circuit board.
