In addition,, more increased its production cost, also demanded urgently improving owing to need two groups of PCI sockets, two groups of grooves extending transversely.

How to realize utilizing the expansion slot structure of a motherboard, can under lower cost burden, make server have the expansion capacity of two adapters at least, obviously looked forward to by relevant industries in easier mode.

In view of above-mentioned, inventor of the present utility model actively seeks solution according to its relevant experience, and for the expansion capacity of server maximum is provided under the most limited space and cost.Inventor of the present utility model at first considers to change the standard form motherboard in order to improve expansion capacity, if can make the standard form motherboard not changing the plant that two PCI adapters still can be provided under its assembly layout, then should be able to effectively solve the above problems.The present utility model people is after constantly studying and studying, finally release the two card of a kind of server-specific pressure-bearing type expansion slot, it comprises that microscler riser on the PCI socket that can vertically be inserted on the standard form motherboard, weldering be located at microscler riser one side for first expansion slot of PCI adapter level plants and weld and be located at second expansion slot of microscler riser another side for another PCI adapter level plant, whereby, make two PCI adapters can along continuous straight runs is horizontal relatively insert on the motherboard.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of applicable to the two card of the server-specific pressure-bearing type on standard form motherboard expansion slot, borrow its ability that level that two PCI adapters can be provided is simultaneously planted, with the extendibility able one of the whole server of effective lifting.
