The present invention relates to connectors, and more particularly, to a peripheral component interconnect express (PCIe)/serial attached small computer system interface (SAS) connector structure.
As a six-channel high speed multifunctional connector, a PCIe/SAS is applied as a solution for multiple applications. The system applying such connector supports single-ended SATA, double-ended SATA Express, double-ended SAS, multi-ended SAS, or a PCIe apparatus with four independent ends at most.
As the data storage mass continuously increasing, the transmission rate of connector has to increase as well. Especially for a server storage industry, it means that the clock rate is increasing and the rising duration is rapidly shortened. Therefore, the requirement upon the bandwidth, which represents the transmission rate, is continuously increased.
Also, the terminal of a conventional SAS0 channel is unable to be applied for transmitting a signal under a PCIe protocol, due to the interval difference between the pins of the SAS0 channel and pins of the PCIe channel.
For improving the issues above, the present invention discloses a PCIe/SAS connector structure, which fulfills the continuously uprising usage demand.
For achieving the aforementioned objectives, a PCIe/SAS connector structure is provided, comprising a body member, a terminal assembly, a cover member, and a fixing plate.
The body member is formed of plastic material and comprises a terminal groove disposed in the body member.
The terminal assembly comprises a signal terminal and a power terminal. The terminal assembly is inserted in the terminal groove inside the body member.
The cover member comprises an electrically conductive plastic member and a metal cover plate. The cover member is structurally formed in a plate shape.
The terminal assembly is inserted in the body member. The cover member is embedded in the body member and disposed at the inner lateral of the terminal assembly.
The metal cover plate is embedded in the electrically conductive plastic member.
Preferably, the fixing plate is disposed at two ends of the body member, respectively, and the fixing plate comprises fixing bore.
More preferably, the fixing plate is disposed at two ends of the body, such that the fixing bore is able to be welded to be fixed on the PCB.
More preferably, the electrically conductive plastic member is divided into at least two sections, so as to reduce a warp deformation thereof.
More preferably, by adjusting the terminal structure for resolving the interval difference between the pins of the SAS0 signal channel and the pins of the PCIe signal channel, the terminal assembly in the present invention is structurally formed to allow the SAS0 signal channel to be applied for PCIe protocol application.
More preferably, the metal cover plate is connected with the electrically conductive plastic member to form a solid cover structure, so as to solve the crosstalk of the signal channel during a high-speed transmission.
More preferably, the electrically conductive plastic member and the metal cover plate are formed by a two-stage formation, so as to be provided with structural stability.
With such configuration, the present invention achieves following advantageous effects.
Compared with conventional techniques, the PCIe/SAS connector structure is advantageous for fulfilling the market demand in the future. First, the terminal structure allows the SAS0 signal channel to be used for PCIe application. Second, the electrically conductive plastic member is connected with the metal cover plate to form a solid cover structure, so as to solve the crosstalk of the signal channel during a high-speed transmission. Third, the electrically conductive plastic member and the metal cover plate are formed by a two-stage formation, achieving a structural stability. Fourth, the cover plate is structurally divided into different sections, so as to reduce the warp deformation. With the optimized structural, the SAS channel achieves the transmission rate of the PCIe channel (32 Gbps for a single channel). Also, a maximum of six channels (X6) are able to be simultaneously applied for transmission.
The aforementioned and further advantages and features of the present invention will be understood by reference to the description of the preferred embodiment in conjunction with the accompanying
