Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Referring to fig. 1 and 2, a high-speed data bus, PCI-express, and USB3.0 are implemented on the golden finger and the connector in a conventional manner using the golden finger and a standard connector, accurate data transmission is implemented by specific parameters of PCB design wiring width, metal layer thickness, and impedance matching, and a board card connected to a first stage and a host needs to share data to a next-stage connector in order to connect the next-stage golden finger in addition to implementing its own function. In order to enable the installation of a plurality of modules, the whole equipment has a neat appearance and a fastening structure and ensure the integrity of signals at the same time, the expansion board card adopts a serial mode, the positions of PCI-express signals passing through PCI-express X4 signals on a host computer are designed into 4 PCI-express X1 signals, each PCI-express X1 signal corresponds to one expansion module, and USB3.0 buses are connected in series layer by layer at the signal positions.
The utility model is characterized in that, the golden finger of preceding one-level integrated circuit board can be inserted in the plug connector of back one-level integrated circuit board. Therefore, the front-stage board card can be cascaded with the rear-stage board card, and high-speed transmission of signals among different board cards is facilitated.
The above description is only for the preferred embodiment of the present invention, and not intended to limit the present invention in any way, and those skilled in the art can make various modifications, equivalent changes and modifications using the above-described technical content, all of which fall within the scope of the present invention.
