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.
The utility model provides a kind of and is called the notion of " IO interface moduleization ", can be applied to embedded industrial computer, business computer or other field.Its main body thinking and PC104, ETX, COM Express are similar, still design difficulty, the higher mainboard core of technology content are partly distributed to board maker, manufacturing, Protean IO interface section are left system integrator for and finished easily.Different is, " IO interface moduleization " requires the mainboard manufacturer not only will the complete whole design of finishing whole mainboard, and its IO interface will be arranged according to certain rule.Like this, system integrator not only can exempt to draw each IO interface with cable under the situation of hardware development, " the IO interface module " that also can develop different application is connected with mainboard by the connector of appointment, reaches the purpose of no cable design (cable less).Guarantee that the product application safety is reliable.
See also Fig. 2, the structural representation of the IO modularization mainboard that provides for the utility model first embodiment.As shown in Figure 2, the IO modularization mainboard that present embodiment provides comprises mainboard body 202, and as the connector 204 of mainboard input/output port, its connector 204 is located at mainboard body 202 1 lateral edges.Therefore, the utility model is integrated the connector 204 that disperses and is concentrated, standard controlling of connector 204, eliminated the in disorder phenomenon of line.These connectors comprise USB port, the network port, serial ports port, GPIO port, VGA port and audio port or the like IO port of using of needing well known to those skilled in the art on computer motherboard.
In the utility model, can select discrete or integrated connector.Please in conjunction with consulting Fig. 3, be the structural representation of the IO modularization mainboard of the utility model second embodiment.The mainboard structure of using discrete connector and integrated connector is provided respectively among the Fig. 2 and first embodiment shown in Figure 3 and second embodiment.As shown in Figure 2, connector 204 can adopt row's needle connector of some discretes as required.Can be respectively the simple and easy ox horn of row's pin (Box pin header) by 2x5pin be connected on the cabinet panel.As shown in Figure 3, also can adopt side by side registered jack as required at the connector 304 of mainboard body 302 1 lateral edges settings.For example, adopt 3 registered jacks respectively as showing and usb signal port, rs 232 serial interface signal port and network signal port.The above-mentioned discrete connector and the particular location and the specification of registered jack will be explained hereinafter.
See also Fig. 4, for according to the IO modularization mainboard of the utility model second embodiment and the connection diagram of cabinet panel.Wherein, IO modularization mainboard comprises mainboard body 402, and at the connector 404 that a lateral edges is provided with, for to distinguish mutually with cabinet panel, is called motherboard connector 404 at this again.Therefore, the utility model is also corresponding to provide a kind of cabinet panel 406, and the one lateral edges is provided with panel connector 408, can be connected with the IO modularization mainboard that the utility model provides.Thisly reduced the design difficulty of system integrator by the registered jack ways of connecting, the connector that is integrated into the IO module is changed flexibly, can arbitrarily increase and decrease the IO port or change the IO modular shape.Motherboard connector 404 and panel connector 408 can adopt the female and row's needle connector of suitable modularization row, though motherboard connector 404 row's of employing needle connectors, panel connector 408 row's of employing female connectors have been shown among Fig. 4, but the utility model is not limited to this, it also can adopt opposite mode, only needs to guarantee that both can cooperate transmission IO signal to get final product.
Therefore, relate to, but both separately connections of simple function of the mainboard that the utility model provides continue traditional use habit by above-mentioned; Also can merge and use the device that is integrated and connected, connect integrated IO module, eliminate connecting line, increase the stability of product.
