Mainboard expanding device

Abstract

The invention discloses a mainboard expanding device. The mainboard expanding device comprises a mainboard, an expansion slot, a mainboard element, an expansion card, an adapter card and a conversion chip, wherein the expansion slot is reserved in the mainboard and meets a first standard; the mainboard element is connected on the mainboard; the expansion card meets a second standard; the adapter card is connected between the expansion slot and the expansion cared; and the conversion chip is used for mutually converting signals meeting the first standard and the signals meeting the second standard. The expansion card is supported by the adapter card and is vertically arranged above the mainboard; an avoidance part is reserved between the adapter card and the mainboard; and the avoidance part can at least partially accommodate the mainboard element. The mainboard expanding device can avoid the position interference between the expansion card and the mainboard element; and the expansion card with large volume can be adopted.

Description

technical field [0001] The invention relates to a main board expansion device, in particular to a main board expansion device for inserting different expansion cards on the main board. technical background [0002] Computer motherboards generally have several different types of expansion slots for plugging in different types of expansion cards, such as AGP (Accelerated Graphics Port, accelerated image processing port) expansion cards, PCI-E (Peripheral Component Interconnect Express, fast external Set component interconnection) expansion card, PCI-X expansion card, etc. The opening direction of the expansion slot is generally perpendicular to the main board, so that the expansion card is plugged into the expansion slot in an upright manner. Various expansion cards of different standards have different sizes. If the expansion slot is plugged with a smaller expansion card, the expansion card will generally not affect the setting of other mainboard components after the expansi...

AI Technical Summary

Problems solved by technology

When using a larger expansion card, such as a PCI-X long card (about 321mm in length), due to the limited space of the motherboard along the extension direction of the expansion slot, the expansion slot and the PCI-X long card will interfere with the heat dissipation module of the CPU. Groups or memory sticks interfere, so the use of PCI-X long cards is limited
