Description

The motherboard assembly

Technical field

The utility model relates to a kind of motherboard assembly, relates in particular to a kind of motherboard assembly that is applicable to embedded system (Embedded System).

Background technology

Embedded system (Embedded System) is the application system that a kind of computer software and hardware combine.The technical fields such as automatic control that are widely used in home appliance, transportation system and the plant produced of daily lifes such as mobile phone, printer, facsimile recorder or video/audio equipment.Embedded system belongs to a kind of computer system, and for general computer system, embedded system has specific purposes and function, and often because the restriction of hardware cost and applied environment etc. need be tailored a new hardware environment for it.

Fig. 1 is a kind of side sectional view of known embedded computer motherboard.As shown in Figure 1, motherboard (mother board) 1a is provided with central processing unit (CPU), internal memory (memory), input and output electron devices such as (I/O), wherein contains the driver of controlling these electron devices and the application program of carrying out specific function etc.Side at this motherboard 1a is provided with an expansion slot (slot) 10a in addition.This expansion slot 10a is generally the interface specification of PC/104, and expansion adapter (expansion board) 11a can peg graft on it.This expansion adapter 11a is positioned at the top of motherboard 1a, and is provided with this motherboard 1a horizontal interval, on its side with respect to motherboard 1a expansion slot 10a, is vertically installed with a plurality of pins (pin) 12a of downward extension.And when each pin one 2a was plugged on this expansion slot 10a, motherboard 1a just can utilize this expansion adapter 11a, thereby increases extra function.Simultaneously, because motherboard 1a is provided with expanding adapter 11a horizontal interval,, helps this embedded computer motherboard and in various hardware devices, use so can effectively reduce both spaces shared when vertically being provided with.

Yet, owing on this motherboard 1a above-mentioned many electron devices must be set, and these electron devices generally all concentrate on motherboard 1a central part, so this motherboard 1a can only dispose this expansion slot 10a at its side.In addition, this motherboard 1a only relies on an expansion slot 10a and expansion adapter 11a to peg graft, thereby cause expanding adapter 11a when being connected with motherboard 1a, as cantilever, be connected on the motherboard 1a, thereby make it structurally very built on the sand, especially in vibrations or comparatively under the bad working environment, cause getting loose of plugging position easily, even may be under compressing or external force influence and damage.

As from the foregoing, above-mentioned known embedded computer motherboard has shortcoming existence such as the inconvenience of use, and remains to be improved.

Designer of the present utility model, concentrates on studies in conjunction with the experience of being engaged in the sector for many years at above-mentioned defective, in line with excelsior spirit, has designed the utility model.

Content of the present utility model

Fundamental purpose of the present utility model is to provide a kind of motherboard assembly, utilizes two transmission interfaces and makes motherboard be connected more firmly between adapter with expanding, and helps to increase number of pin, thereby improves transfer rate.

Another purpose of the present utility model is to provide a kind of motherboard assembly, the mode of repeatedly putting by level, and a plurality of expansion adapters are repeatedly put in the compartment of terrain on motherboard, thus make motherboard expand more function.

In order to realize above-mentioned fundamental purpose, the utility model provides a kind of motherboard assembly, comprises that a motherboard and interval repeatedly are placed on the expansion adapter on this motherboard; Wherein, described motherboard has a motherboard, and described expansion adapter has a daughter board, all have two relative sides on motherboard and the daughter board, and two sides of described motherboard are corresponding with two sides of described daughter board again, and two transmission interfaces are separately positioned on the dual-side of this motherboard and daughter board.Described motherboard is repeatedly put with expanding the adapter level, and is electrically connected by described two transmission interfaces; Since motherboard with expand adapter and repeatedly put after, two transmission interfaces lay respectively at its both sides, so realized the fundamental purpose of the present utility model that makes one-piece construction more firm.

In order to realize another above-mentioned purpose, the utility model provides a kind of motherboard assembly, it further comprises an other expansion adapter, described other expansion adapter repeatedly is placed on original described expansion adapter at interval, and carries out described two electrical connections of expanding between adapter by two other transmission interface.Can constantly make progress like this and repeatedly put the expansion adapter, thereby realize above-mentioned another purpose of the present utility model.

Motherboard assembly one-piece construction of the present utility model is firm, and can place a plurality of expansion adapters, makes motherboard expand more function.

Embodiment

Below in conjunction with accompanying drawing feature of the present utility model and technology contents are elaborated, listed accompanying drawing formula is only for reference, is not to restriction of the present utility model.

Fig. 2, Fig. 3, Fig. 4 are respectively three-dimensional exploded view, three-dimensional combination figure and the side sectional views of the utility model first embodiment.As Fig. 2, Fig. 3 and shown in Figure 4, the utility model provides a kind of motherboard assembly, comprises that 1 and interval of a motherboard (mother board) repeatedly is placed on the expansion adapter (expansion board) 2 on this motherboard 1; Wherein:

This motherboard 1 is roughly the same with general known motherboard, has a motherboard 10, this motherboard 10 is a printed circuit board (PCB) (PCB), be used for carrying out circuit layout, and on this motherboard 10, be provided with central processing unit (CPU), internal memory (memory), input and export electron devices such as (I/O), and wherein contain the driver of controlling these electron devices, and the application program of execution specific function etc.In addition, have two

sides

11,12 respect to one another on this motherboard 10, these two

sides

11,12 are used for being provided with hereinafter described expansion slot (slot) 30.

The function that this expansion adapter 2 expands according to 1 desire of motherboard and designing has a daughter board 20 that is used for circuit layout, motherboard 10 sizableness of this daughter board 20 and this motherboard 1, and repeatedly put with motherboard 10 intervals the top that is positioned at this motherboard 1.Also have dual-
