Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a SAS high-speed connector female head. Background Technology

[0002] Serial SCSI (SAS) connectors are the mainstream interconnect devices for enterprise storage applications. These small form factor (SFF) standard connectors are designed to support differential signaling and drive performance improvements. SAS interface technology is backward compatible with SATA. The backplane of a SAS system can connect to both dual-port, high-performance SAS drives and high-capacity, low-cost SATA drives. SAS can seamlessly integrate with SATA and some SCSI devices. Current SAS 4.0 bandwidth is above 16Gb / s, with a maximum of 24Gb / s, for servers and storage devices, HDDs, HDD bays, and SSDs. Currently, some SAS connectors are required to meet the SAS 4.0 transmission standard.

[0003] In the prior art, the structure of the SAS connector can be found in Chinese patent documents CN 205680817U, CN208284706U and CN204376132U. Its structure includes an insulating body, multiple power metal terminals, multiple ground metal terminals and multiple signal metal terminals. Multiple terminal slots are provided inside the insulating body, and the power metal terminals, ground metal terminals and signal metal terminals are respectively inserted into the corresponding terminal slots. However, existing SAS connectors still have the following technical problems: First, during high-speed signal transmission, the signal metal terminals inside the SAS connector are easily affected by external signal interference, and crosstalk between the metal terminals is also likely to occur, leading to signal loss, incompleteness, and instability. Second, during high-speed signal transmission, the rear ends of the metal terminals in the SAS connector need to be soldered to the PCBA board and connected through the PCBA board. Furthermore, there is no grounding shielding structure between the rear ends of the metal terminals, making them susceptible to external signal interference and crosstalk between the rear ends of the metal terminals, resulting in signal loss, incompleteness, and instability, and failing to meet the PCIE 5.0 standard requirements. Third, the metal terminals of existing SAS connectors need to be inserted into the terminal slots of the insulating body separately, which is inconvenient for installation. Utility Model Content
