Abstract

A motherboard expansion device is designed to connect a motherboard which conforms to a first standard with an expansion card which conforms to a second standard in an expanding way. The motherboard expansion device comprises a first slot conforming to the first standard arranged on the motherboard, a second slot conforming to the second standard, an expansion slot in which the expansion card can be inserted, and a switchover card. The second slot is connected with the expansion slot, and both of the second slot and the expansion slot are arranged on the motherboard. The switchover card is provided with a first connector connected with the first slot, a second connector connected with the second slot, and a conversion chip which can convert the signal conforming to the first standard and the signal conforming to the second standard into each other.

Description

The mainboard expanding unit

Technical field

The utility model is about a kind of mainboard expanding unit, particularly a kind of expanding unit of the different expansion boards that are used for pegging graft on mainboard.

Technical background

General computer main board is provided with several different types of expansion slots in order to different types of expansion board of pegging graft, as AGP (Accelerated Graphics Port) expansion card, PCI-E (Peripheral ComponentInterconnect Express) expansion card etc., but the chipset that common mainboard is adopted can not be supported each expansion card, when the unsupported expansion card of needs grafting chipset, need usually by adapter switching.

Present adapter mostly is vertical card (riser card), vertical card is provided with an inserting groove, one side of vertical card is provided with a metal pin, at first the metal pin with vertical card is plugged in the expansion slot corresponding on the mainboard, then expansion board is plugged in the inserting groove of this vertical card, so, can make expansion card be in the state of paralleling with mainboard.

But the expansion card that is plugged on the vertical card is the expansion card of various different patterns, it is not of uniform size, if what peg graft is the less expansion card of volume, then the mainboard upside has enough spaces to hold expansion card, but if need the bigger expansion card of grafting volume, after then expansion card is plugged on the vertical card, this expansion card may be with element on the motherboard or other expansion card interference and is caused system's instability, or because limiting this expansion card and can not being plugged on the vertical card at all of space can't realize expanded function.

Summary of the invention

In view of above content, be necessary to provide a kind of avoid expansion card and other element interferences expanding unit.

A kind of mainboard expanding unit, be used for a mainboard expansion connection one that meets one first standard is met the expansion card of one second standard, described mainboard expanding unit comprises one first slot that meets described first standard, described first slot is arranged on the described mainboard, described mainboard expanding unit also comprises one second slot that meets described second standard, one expansion slot and the adapter that can peg graft described expansion card, described second slot is connected with described expansion slot and all is arranged on the described mainboard, and described adapter is provided with first connector that links to each other with described first slot, one second connector that links to each other with described second slot and one can will meet the signal of described first standard and meet the conversion chip that the signal of described second standard is changed mutually.

Compared with prior art, the utility model is set directly at the expansion slot on the adapter on the mainboard, avoided being plugged on this expansion slot expansion card since be subjected to the space restriction and with mainboard on other element interferences.

Embodiment

See also Fig. 1 and Fig. 2, the utility model mainboard expanding unit is used for expansion connection expansion card on a mainboard 10.This mainboard expanding unit comprises an adapter 20 and an expanding element 30.

Mainboard 10 is provided with a chip 11, this chip 11 is an I/O chip, 11 of chips are supported the signal transmission of accord with PCI-E standard in the present embodiment, and mainboard 10 is provided with the PCI-E expansion slot 13 of some accord with PCI-E standard, and these PCI-E expansion slot 13 link to each other with chip 11 by bus.Expanding element 30 is arranged on the mainboard 10, expanding element 30 comprises one first slot 32 of accord with PCI-E standard, one second slot 33 and a PCI-X expansion slot 35 of accord with PCI-X (Peripheral Component Interconnect Extend) standard, first slot 32, second slot 33 and PCI-X expansion slot 35 all are arranged on the mainboard 10, first slot 32 links to each other with chip 11 by bus, and second slot 33 links to each other with PCI-X expansion slot 35.

See also Fig. 1 and Fig. 3, adapter 20 comprises a circuit board 21, circuit board 21 is provided with first connector 22 of one accord with PCI-E standard and second connector 23 of one accord with PCI-X standard in its same side, first connector 22 can match with first slot 32, second connector 23 can match with second slot 33, also be provided with a conversion chip 25 on the circuit board 21, this conversion chip 25 links to each other with second connector 23 with this first connector 22 respectively, can be implemented in the conversion between the signal of the signal of accord with PCI-X standard and accord with PCI-E standard, thereby first connector 22 and second connector 23 that will transmit the various criterion signal couple together.

See also Fig. 4, when needing to peg graft the PCI-X expansion card on the mainboard 10, first connector 22 of adapter 20 is plugged in first slot 32 of expanding element 30, second connector 23 is plugged in second slot 33 simultaneously, then the circuit board 21 of adapter 20 is set to be parallel to mainboard 10, the PCI-X expansion slot 35 of mainboard 10 is connected to chip 11 by adapter 20, and and the communication of 11 formations of chip, for example chip 11 will transfer data to PCI-X expansion slot 35, then the data of Chuan Songing are at first delivered to first slot 32 by chip 11, then deliver to conversion chip 25 by first connector 22 that links to each other with first slot 32, conversion chip 25 is converted to the data of accord with PCI-X standard with the data of this accord with PCI-E standard, and passes through second connector 23, second slot 33 and be sent to PCI-X expansion slot 35.

In the above-described embodiments, on the mainboard 10 of this accord with PCI-E standard, expand with adapter 20 by expanding element 30 and to be connected the expansion card that meets the PCI-X standard, design by the design, other expanding element and adapter also can further be set this mainboard 10, be connected on this mainboard 10 with the expansion card of realizing meeting other standards expansion card etc. of AGP standard (as meet) expansion; And mainboard is not limited to the mainboard 10 of this accord with PCI-E standard, also can be the mainboard that meets other standards, meets the expansion card of PCI-X standard etc. as expansion connection on the mainboard of accord with PCI standard.
