General PCI/ISA BUS single-borad computer host card is the connection leg that adds PCT BUS after the connection leg of ISA BUS, the common then corresponding single-borad computer host card of PCI/ISA BUS backboard, and after the slot of ISA BUS, add the slot of PCI BUS, so that the ISA pci bus is connected, as depicted in figs. 1 and 2, the connection leg that veneer host card 1 commonly used is located at a side is divided into ISA connection leg 11 and PCI connection leg 12 two parts, this PCI connection leg 12 is to arrange the rear that is positioned at ISA connection leg 11, and form the form of a straight line, and on the backboard 2 with respect to the connection leg of single-borad computer host card 1, be the rear that PCI slot 22 is placed in EISA slot 21, form the mode of a straight line equally; During plant single-borad computer host card 1, then ISA,

PCI connection leg

11,12 are inserted in the relative slot 21,22, in this way, though can reach the purpose of using three kinds of buses, but virtually the length lengthening of backboard 2 with single-borad computer host card 1, cause whole area to increase, so that the length of PCI/ISA BUS single-borad computer host card 1 is the length that the length of ISA BUS adds PCIBUS at least.

The purpose of this utility model is to propose a kind of a kind of enhancing industrial standard (EISA) bus connection leg and slot of being made up of single-borad computer host card and backboard thereof, wherein the plug-in card connection leg of single-borad computer host card is to form two rows, and the eisa bus slot on the backboard is upper and lower two-layer clamp structure, therefore it can utilize eisa bus specification pin to connect signal and the slot that uses pci bus and isa bus, and then dwindled the volume of computer after the assembling, thereby solved the existing in prior technology problem.

The technical scheme that the utility model adopted is that it consists predominantly of single-borad computer host card and backboard, wherein the single-borad computer host card is to use eisa bus specification pin to hold the signal of PCI and isa bus, via the EISA connection leg information is sent on the backboard, this single-borad computer host card becomes the inserting mode of plug-in card, its below is provided with the connection leg of plug-in card, this connection is the mode that forms two rows, superstructure is the signal of isa bus, understructure is the signal of pci bus, just under the framework of eisa bus, can use PCI and isa bus simultaneously, each connection leg is to be formed with a plurality of contact feets position, is connected with circuit on the single-borad computer host card respectively.

This backboard is provided with several slots, be respectively isa bus slot, eisa bus slot and pci bus slot, each slot all is to use the mode of clamping, in the connection leg of various plug-in cards is held on, reach the transmission of signal, and each pin position of all slots is into the state of mutual binding, with by different bus transfer; Eisa bus slot on this backboard is upper and lower two-layer clamp structure, the first and third clamping pin position of classifying lower floor as in this eisa bus slot, link with pci bus, PCI pin position/signal as clamping single-borad computer host card, and second, four classify the clamping pin position on upper strata as, link with isa bus, as the ISA pin position/signal of clamping single-borad computer host card.

The utility model is owing to have the design feature of levels, so it can use eisa bus specification pin to connect signal and the slot that uses pci bus and isa bus, and then can dwindle the volume of assembling back computer.
