Description

SATA electrical connector

This creation relates to a connector, and in particular to a SATA electrical connector.

The SATA (Serial Advanced Technology Attachment) interface is the abbreviation of Serial ATA, which is Serial ATA. This is a new type of interface that is completely different from Parallel ATA, named after the serial transmission of data. The SATA bus uses embedded clock signals for greater error correction. Compared with the previous technology, its biggest advantage is that it can check the transmission instructions (not just the data). If the error is found, it will be automatically corrected. The reliability of data transmission is greatly improved. The sequence interface also has the advantages of simple structure and support for hot plugging.

SATA electrical connectors are mostly used in devices such as hard drives, CD players or motherboards, and SATA electrical connectors can be divided into device-side SATA electrical connectors depending on the type of device being plugged in.
