Extending device of abstraction type adapting card

Abstract

The invention relates to an extraction adapter expansion device, which is glidingly positioned in a shell for at least one adapter to be plugged in, the shell is opened with an opening, the shell is internally provided with a mainboard and at least one adapter slot corresponding to the adapter. The extraction adapter expansion device comprises: an extraction frame, which can glidingly pass through the opening and be fixed in the shell; an expansion circuit board, which is fixedly provided in the extraction frame, the expansion circuit board has at least one expansion slot for the adapter to be plugged in; an interface switching device, which is electrically connected with the expansion circuit board and the adapter slot of the mainboard, so as to make sure that the adapter is electrically connected with the mainboard. The invention is able to switch device or switch circuit board through an interface, switches electrical signal to the mainboard of a computer, changes the connection relation between adapter and adapter slot, effectively simplifies procedure of changing adapter and saves time of installing operation, so as to improve efficiency of integral operation.

Description

technical field [0001] The invention relates to an expansion device for a peripheral adapter card of a computer, in particular to a removable adapter card expansion device for a computer device. Background technique [0002] At present, on the main board of the computer system, in order to cooperate with the use of the peripheral devices by the user, there are many adapter card slots with different interfaces, so as to provide adapter cards for various output / input devices around the computer. The data transmission interfaces of peripheral devices are different, such as AGP (Accelerated Graphics Port), PCI (Peripheral Component Interconnect) or ISA (Industry Standard Architecture), etc., and these adapter cards inserted in the adapter card slots can be used To enhance the overall functions of the computer and support special interface devices to meet the different needs of various users for computer systems. [0003] As far as general computer mainframes are concerned, vari...

Problems solved by technology

[0005] Based on the disclosure of the above-mentioned cases, the connection relationship between the adapter card and the motherboard is that the adapter card is directly inserted into the adapter card slot of the motherboard with its metal pins, so as to electrically connect the adapter card to the motherboard circuit. effect, but this connection method restricts the adapter card to be directly installed and plugged on the motherboard. Of course, since the motherboard is fixed inside the computer case, when the user replaces the adapter card, there is no problem. The cover of the computer case must be disassembled before replacement can be performed, and when the installation or plugging procedures are completed, the cover of the computer case needs to be put back on the host and locked, and the computer case itself is quite Difficult to disassemble and lock, the casing itself and the screw parts of the body are often not easy to match, resulting in complex and time-consuming procedures for disassembling and assembling the adapter card
