Background technology

Along with the evolution of integrated technique and the demand of portability, product miniaturization, many interfaces and low cost are the trend of modern motherboard design.But owing to reducing of mainboard size, the space that can provide element to put on the plate is more and more littler, limited the design of many I/O of integrated circuit board interface, and employing unit connector (complex connector), be the stacks physically of a plurality of connectors, this will inevitably bring the increase of flaggy, and increases the process complexity that flaggy has improved cost and the PCB of PCB undoubtedly.

The back yard industry computing machine adopts bus standard PC/104 bus extended mode mostly at present, it includes ISA (Industrial Standard Architecture, the industrial standard architectures interface), PCI (PeripheralComponent Interconnect, the peripheral component interconnection interface), PCI-E (PCI-Express, quick PCI) independence and the combination expansion of bus such as, this technology has following shortcoming:

1, the bus scalability is single, can not satisfy the requirement of many Extended Protocols, in the face of different customer demands will redesign mainboard and cabinet, lacks dirigibility.

2, owing to will redesign mainboard and cabinet, make the expansion cost increase at different customer demands.

3, the interface area occupied is bigger, can not satisfy miniaturization of products requirement.

4, need repeatedly exploitation, increased research and development time and R﹠D costs.

The utility model content

The purpose of this utility model is to provide a kind of mainboard, I/O expansion card and industrial computer, is intended to solve that existing bus extended mode scalability is single, expansion cost height, problem that the interface area occupied is big.

The utility model is achieved in that a kind of mainboard, and described mainboard is provided with expansion bus interface, and described expansion bus interface is provided with and makes it support the pin of multiple expansion bus.

Further, described expansion bus comprises one or more in ISA industrial standard architectures, PCI peripheral component interconnection, the quick PCI of PCI-E, HD/A HD Audio, AC ' 97 codecs, USB USB (universal serial bus), LPC low pin count bus, SMBUS System Management Bus, the SDVO serial digital video output bus.

Another purpose of the present utility model is to provide a kind of I/O expansion card, and it is connected with the expansion bus interface of mainboard as mentioned above by one or more connectors; Pinout that described I/O expansion card is pinout and described connector and the I/O expansion card that is complementary with the definition of the bus interface of the above expansion bus interface.

Further, described I/O expansion card is the L shape.

Further, described I/O expansion card is rectangular.

Another purpose of the present utility model is to provide a kind of industrial computer, comprises aforesaid mainboard and aforesaid I/O expansion card.

In the utility model, the definition of bus interface has the extendible different I/O expansion card of expansion bus interface of multiple bus protocol, broken through the limitation of back yard industry computing machine employing PC/104 bus standard, realize the flexible expansion of I/O function and select for use, shorten the research and development time greatly, reduce research and development and expansion cost, simultaneously by in a bus interface, defining various protocols, make the design of original a plurality of interface physics stacks obtain simplifying, satisfy the microminiaturization of mainboard volume, satisfy different clients' customized demand.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Among the utility model embodiment, bus interface to expansion bus interface defines, can be provided with according to actual needs and comprise multiple bus protocol, the final selection of the function of the I/O expansion card of Shi Yonging is used with one or more connectors as required, and this connector has the pinout that the bus interface definition with above-mentioned expansion bus interface is complementary.

Fig. 1 shows the structure of the mainboard that the utility model embodiment provides, and for convenience of description, only shows the part relevant with the utility model.

With reference to Fig. 1, mainboard 1 comprises expansion bus interface 12, wherein the definition of the bus interface of expansion bus interface 12 has multiple bus protocol, be provided with the pin of supporting multiple expansion bus, for example comprise ISA, PCI, PCI-E, HD/A (High Definition Audio, HD Audio) or AC ' 97 (Audio Codec97, codec), USB (Universal Serial Bus, USB (universal serial bus)), LPC (Low Pin Count, low pin count), SMBUS (System management bus, System Management Bus) one or more and among the SDVO (Serial Digital Video Output, serial digital video output).When should be appreciated that concrete enforcement, can define flexibly bus protocol according to actual needs, be not limited to above-mentioned several.

Expansion bus interface 12 is connected with the I/O expansion card by one or more connectors, need the corresponding connector of function selecting of the I/O expansion card of use as required, the pinout of I/O expansion card and the pinout of this connector, and the definition of the bus interface of above-mentioned expansion bus interface 12 is complementary, as Fig. 2 A and 2B is the pinout example of two high density 2*40 connectors, comprising partial bus agreement mentioned above, (5.80mm * 39.30mm) is also much smaller than the size of the connector of traditional PC/104 (10.03mm * 81.79mm) for its single size, the interface size also further reduces, and satisfies the microminiaturized demand of mainboard volume.Simultaneously, the connector that can also select at a high speed, Electro Magnetic Compatibility is good is to adapt to the expansion bus that transfer rate and electromagnetic screen etc. is had higher requirements.
