Method for achieving high-density reliable expansion of ATX mainboard

Abstract

The invention discloses a method for achieving high-density reliable expansion of an ATX mainboard, and relates to the field of mainboard expansion; a PCI / PCIE expansion backboard independent of the mainboard is arranged, and is in perpendicular insertion connection with the mainboard through a CPCIE connecting unit, so that a PCI / PCIE expansion card installed in the PCI / PCIE expansion backboard is parallel to the mainboard, laminating placement is formed, and the expansion is achieved. Through the utilization of the method for achieving the high-density reliable expansion of the ATX mainboard, a PCI expansion part function on the ATX mainboard is innovatively and independently divided, the expansion plate is formed, the richness of a mother board function is guaranteed, and the flexibility of the expansion is achieved at the same time; the fixation form of the PCI / PCIE expansion card is innovatively changed from being perpendicular to the mother board into being parallel to the mother board, and the expansibility during light and thin machine case design is satisfied at the same time; the high-speed reliability of the CPCIE connecting unit is utilized to guarantee interconnection of the expansion card and a CPU.

Description

technical field [0001] The invention discloses a method for realizing expansion of a mainboard, relates to the field of mainboard expansion, in particular to a method for realizing high-density and reliable expansion of an ATX mainboard. Background technique [0002] ATX motherboards are divided into standard ATX, mATX, ITX and mITX according to the size. Usually, the larger the size, the higher the performance of the motherboard, the more PCI and PCIE slots attached, and the stronger the scalability; on the contrary, the size The smaller the size, the fewer expansion slots, especially when the size of the motherboard is reduced to ITX level, only 1 to 2 expansion slots can be reserved. In addition, the direction of the traditional PCI slots is perpendicular to the motherboard, resulting in the thickness of the whole chassis being affected by the height of the PCI expansion card. Restrictions limit the development of its thinning and frivolity. [0003] At present, users ha...
