When an ISA interface is needed for assistance, the ISA interface can be connected to the mainboard by using the expansion module with quick replacement and high maneuverability, and the mainboard can be elastically used.
Description
Technical field
The present invention relates to a kind of ISA (industry standard architecture) enlargement module, particularly a kind of escapable cost and the kind of DC power source inverter that is convenient for changing of computing machine.
Background technology
Industrial standard architectures ISA (INDUCTRIAL STANDARD ARTHITECTURE) is one 8 or 16 a data bus standard socket, also be from 8088,8086 until 80386 epoch were best-known bus specification, until Pemtium all still kept the design compatible with it, even up till now, the design of each tame motherboard has still kept the slot of ISA interface; ; because the speed of ISA has only 8MHz; transmission speed is slow excessively; the CPU (central processing unit) of high frequency running and peripheral element thereof can't have been caught up with; therefore; each tame motherboard; gradually, pci bus has at a relatively high speed replaced isa bus; but owing to still have the demand of ISA slot on the market, manufacturer is different demands of dealing with market; usually can offer the motherboard that the consumer has the ISA slot; and do not have a motherboard of ISA slot, and the manufacturer of a tame foundry might be because of the difference of vicarial manufacturer, and its ISA slot count that need be located on the motherboard is also different thereupon; Must offer different production lines simultaneously and be produced, above-listed all situations, not only cost is higher, maneuverability is low again, do not have elasticity and easily cause the stock, more a cost of stock buildup; And for the user, do not have a motherboard of ISA slot if bought, if when meeting desire use ISA slot additional card, then need in addition the monoblock motherboard to be changed, the consumption cost and the elasticity of not having, in view of this, the present invention is with interface that the ISA slot can more flexible replacing be arranged and to improve maneuverability be that purpose has been created kind of DC power source inverter.
Summary of the invention
Fundamental purpose of the present invention provides a kind of kind of DC power source inverter, with the effect that reaches escapable cost and be convenient for changing.
Therefore, principal character of the present invention is that at least one group of ISA slot is located on the expansion board; And by linkage unit set on expansion board and motherboard and connect the signal transmission unit of this two linkage unit, make the motherboard can more flexible use, to reach the effect of saving cost and being convenient for changing.
For achieving the above object, the invention provides a kind of DC power source inverter, can expand usefulness for a computer main frame panel, it is characterized in that this enlargement module includes one first linkage unit, an expansion board and a signal transmission unit; This first linkage unit, be located at the certain position place of this motherboard with CPU (central processing unit) and peripheral element, this expansion board, have at least one group of ISA slot, and correspondence is provided with one second linkage unit on expansion board, and this second linkage unit, one end is electrically connected on this ISA slot through a bridge-jointing unit, and this bridge-jointing unit is the PCI-ISA bridging chip, can be used as pci interface and is connected bridge with circuit between the ISA interface; One signal transmission unit is electrically connected to respectively on first linkage unit and this second linkage unit in order to transmit electric signal; Therefore, when this signal transmission unit was connected to this two linkage unit, the additional card of being located on the ISA slot can reach signal on the peripheral element and CPU (central processing unit) of motherboard, made the motherboard can more flexible use.
Relevant the present invention reaches technological means and the effect thereof that above-mentioned purpose, feature adopt, and exemplifies preferred embodiment now and accompanying drawings is as follows.
Description of drawings
Fig. 1 is the block schematic diagram of preferred embodiment of the present invention.
Fig. 2 is the structural representation of preferred embodiment of the present invention.
Embodiment
At first please refer to shown in Fig. 1 and 2, the present invention expands for a computer main frame panel 1 to use, wherein, this motherboard 1 has the peripheral element that a CPU (central processing unit) 10 reaches as chipset 11, groups of slots 12 or the like in this preferred embodiment, the present invention then provides one can expand the ISA enlargement module 2 of usefulness for this motherboard 1, include one first linkage unit 3, an expansion board 4 and a signal transmission unit 5, wherein:
This first linkage unit 3, in this preferred embodiment, this first linkage unit 3 is to have a PCI slot 30 and a power supply slot 31, wherein, this PCI slot 30 is near being located on the side 100 of motherboard 1 31 sides of being located at this PCI slot 30 of this power supply slot.
This expansion board 4, it in this preferred embodiment a printed circuit board (PCB), wherein, be provided with two groups of ISA slots 40,41 in its one side that is printed on P.e.c., close these expansion board 4 one sides 400 places then correspondence are provided with one second linkage unit 42, and in this preferred embodiment, this second linkage unit 42 is to have a PCI slot 420 and a power supply slot 421, this PCI slot 420 is near being located at expansion board 4 its side 400 places, 421 sides of being located at this PCI slot 420 of this power supply slot; In addition, this expansion board 4 also has a bridge-jointing unit 43, and in this preferred embodiment, this bridge-jointing unit 43 is to be the PCI-ISA bridging chip, can be used as pci interface and is connected bridge with circuit between the ISA interface.
This signal transmission unit 5, formed by a PCI cable 50 (PCI CABLE) and a power cable 51 (POWER CABLE) in this preferred embodiment, wherein, this PCI cable 50 is the PCI slots 420 in order to the PCI slot 30 that connects this first linkage unit 3 and this second linkage unit 42, in order to the circuit signal in the transmission pci bus, this power cable 51 is then in order to the power supply slot 31 that connects first linkage unit 3 and the power supply slot 421 of this second linkage unit 42, in order to transmit power supply.
Therefore, when the user need use the ISA interface maybe will expand the ISA interface, its PCI cable 50 can be connected the PCI slot 30 of first linkage unit 3 and the PCI slot 420 of this second linkage unit 42, connect the power supply slot 31 of last first linkage unit 3 and the power supply slot 421 of this second linkage unit 42 with a power cable 51 again, after connection was finished, the user can reach and use the ISA interface or reached the purpose of expansion ISA interface.
Therefore, by above-mentioned ISA enlargement module structure, manufacturer can be because of the mainstream demand in market, will not be located on the motherboard by the ISA interface, and only need on motherboard, to establish the PCI slot and add power supply slot, whole cost is reduced, when if some systems of chance need the support of ISA interface, can use as long as utilize enlargement module of the present invention to be connected on the motherboard, change fast and maneuverability high, and make the supply of manufacturer have more elasticity.
In sum, kind of DC power source inverter structure of the present invention really can be passed through described structure, device, reaches its intended purposes and effect.
Above accompanying drawing and explanation are embodiments of the invention only, are not for limiting enforcement of the present invention; Those skilled in the art does other equivalences according to the present invention and changes or modification, all should be encompassed in the claim scope of the present invention.
