Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a SAS high-speed connector male head. Background Art

[0002] Serial Attached SCSI (SAS) connectors are a mainstream interconnect device 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 SAS system's backplane can connect both dual-port, high-performance SAS drives and high-capacity, low-cost SATA drives. SAS seamlessly integrates with SATA and some SCSI devices. The current SAS 4.0 bandwidth exceeds 16Gb / s, reaching a maximum of 24Gb / s, and is used in servers and storage devices, HDDs, HDD carriers, and SSDs. Currently, some SAS connectors are required to meet the SAS 4.0 transmission standard.

[0003] In the prior art, the structure of a SAS connector can be found in Chinese patent documents CN 205680817U, CN208284706U, and CN204376132U. The structure includes an insulating body, multiple power metal terminals, multiple ground metal terminals, and multiple signal metal terminals. The insulating body is provided with multiple terminal slots, and the power metal terminals, ground metal terminals, and signal metal terminals are respectively inserted into corresponding terminal slots.

Furthermore, the metal terminals of existing SAS connectors need to be individually inserted into the terminal slots of the insulating body, making installation relatively inconvenient.
