Electrical connector

This creation is about an electrical connector.

Serial Attached SCSI (SAS) is a communication protocol that primarily regulates the access of data to computer storage devices such as hard drives or tape drives. SAS is a point-to-point serial protocol that replaces the parallel SCSI bus technology introduced in the mid-1980s. The SAS device uses differential signals for communication. The differential signal can reduce the adverse effects of capacitive, inductive and noise encountered by parallel SCSI in high-speed data transmission, thus achieving stable and high-speed serial communication. ).

Each SAS device includes at least one transceiver mechanism, the transceiver mechanism including a transmitter and a receiver. Two pairs of wires can be used to connect the transmitters in the connection ports of the two SAS devices and the corresponding receivers. The connection between the two devices can be connected to the connector using a connecting cable. Figure 1A shows an existing SAS connector 1. The SAS connector 1 can be soldered to the circuit board 2. The SAS connector 1 includes a terminal group 11, and the terminal group 11 can include two pairs of differential signal terminals, wherein each pair of differential signals is between the two ground terminals. Each terminal of the terminal block 11 has a solder fillet 111, and the solder fillet 111 is bent to extend parallel to the circuit board 2. Corresponding pads 21 can be disposed on the circuit board 2, and the pads 21 are equal in length. The solder pads 111 of the terminals of the terminal group 11 can be soldered to the corresponding pads by surface mount technology. 21, as shown in Figure 1B.

The physical connection rate of the SAS connector 1 is 6.0 Gbps. A new generation of SAS will be introduced in the near future, and the physical link rate of the new generation of SAS will further double the existing physical link rate to 12Gbps. When the physical connection rate is increased to 12 Gbps, the combination of the existing SAS connector 1 and the circuit board 2 can cause severe electromagnetic interference (EMI emission) problems.
