Description

Computer motherboard

(1) technical field

The utility model mainly relates to a kind of computer motherboard.

(2) background technology

Basically have an input connectivity port, network connection port, data output connectivity port and an audio-visual output connectivity port on the computer motherboard of existing P C99 type.Wherein, connect at network and to be equipped with two USB (universal serial bus) (USB) in the port, its mainly be a kind of plug and play type connector like this, the user then can directly use any hardware by this connector.That is to say, the user operating computer need to use a kind of hardware midway the time, the user can directly utilize USB, and start that need not be again and wait for computer system by detecting and install supervisor, and can directly use initiate hardware.

The user it seems that by existing PC99 motherboard wherein itself has promptly had two USB, so can utilize existing specification to enjoy the convenience of plug and play; Yet along with making rapid progress of science and technology, two existing USB do not apply already and use, so, how to go to expand prior USB, be an important problem of industry already.

As previously mentioned, existing PC99 motherboard mainly has an input connectivity port, network connection port, data output connectivity port and an audio-visual output connectivity port, so the existing practice of setting up extra two USB is not to juggle things on existing network connection port outward all, or data are exported the connectivity port or audio-visual output connectivity port is moved, so that install needed USB in the original place.The above-mentioned various practices, its result all can change existing specification, so that influence is very big.Because existing PC99 specification is accepted by the whole world already,, and also not the situation that the dealer was happy to see wherein because change the cost of designing institute initiation too high so it is wide excessively to change the problem that existing specification involves.

(3) utility model content

The main purpose of the utility model is to provide a kind of improved computer motherboard, can under not changing existing specification needed USB be added in the motherboard of existing specification, and meet request for utilization fully.

For achieving the above object, computer motherboard of the present utility model, has an input connectivity port, network connection port, a data output connectivity port and an audio-visual output connectivity port, wherein, have two the one USB in this network connection port, be characterized in: data output connectivity port has one first output connectivity port, one second output connectivity port and one the 3rd output connectivity port, the first output connectivity port is to be positioned at the top that the connectivity port is exported in the mutual in twos second output connectivity port and the 3rd side by side, separated by one first support body therebetween, the first output connectivity port and mutually side by side the second output connectivity port and the 3rd output connectivity port between then define one first space, so that two the 2nd USB to be set, it is to be connected on the substrate of computer motherboard that three pins are wherein arranged in each USB, and the 4th pin then is the screw that is connected in first support body with as ground connection.

For further specifying the purpose of this utility model, design feature and effect, the utility model is described in detail below with reference to accompanying drawing.

(5) embodiment

Please, has an input connectivity port 1 in the PC99 computer motherboard of the present utility model, network connection port 2, one data output connectivity port 3 and an audio-visual output connectivity port 4 referring to Fig. 1.

As shown in Figure 2, input connectivity port 1 has two jacks 11,12, and it can supply with mouse respectively and keyboard (all not showing) links.

Network connection port 2 has a network socket 21, for example is telephone wire, T1 special line or any circuit that is available for users to link the internet to be available for users to insert.Below network socket 21, have two the one USB22, to be available for users to enjoy the convenience of plug and play.

Data output connectivity port 3 has one first 31, one second output connectivity port 32, output connectivity port and one the 3rd output connectivity port 33.It seems according to existing specification, the first output connectivity port 31 of data output connectivity port 3 is to be positioned at the top that connectivity port 33 is exported in the mutual in twos second output connectivity port 32 and the 3rd side by side, separated by one first support body 34 therebetween, and also because the setting of this first support body 34, the first output connectivity port 31 and mutually side by side the second output connectivity port 32 and the 3rd output connectivity port 33 between then define one first space 35, and one second space 36.

Audio-visual output connectivity port 4 has one second support body 41, and then defines one the 3rd space 42 between second support body 41.

Referring to Fig. 3 and shown in Figure 4, two the 2nd USB51 of the required increase of the utility model, 52 are arranged in first space 35.Simultaneously, by also seeing the 2nd USB51 among the figure, 52 also can be arranged on the inside in aforesaid second space 36.

Referring to Fig. 3 and shown in Figure 5, two the 2nd USB51 of the required increase of the utility model, 52 are arranged in the 3rd space 42.

Referring to Fig. 2 and shown in Figure 6, no matter be data output connectivity port 3 or audio-visual output connectivity port 4, has connecting line 30 respectively at its rear, 40, it mainly is that connectivity port 31 is exported in supply first or the output connectivity port (not giving label) of 4 tops, audio-visual output connectivity port is connected with substrate 6, based on this, two the 2nd USB51 that the utility model is desired to add, 52 after adding, the binding that itself and substrate are 6 then can utilize the space of 6 of connecting line 30,40 and substrates to be provided with.In figure, can see the 2nd USB51,52 and 6 of substrates be provided with first Wiring area 511 and second Wiring area 521, and in each Wiring area 511,521, then divide and else be provided with three contacts.In this embodiment, though the position of these three contacts is the positions that are provided with significantly in the drawings, yet its set position is not confined to the position shown in the figure.In fact, the 2nd USB51,52 and the connecting point position of 6 of substrates can be any position on the substrate 6, and its purpose only is to be to connect the 2nd USB51,52 and substrate 6 between connection.

Each USB51,52 all have four pins, and three contacts are only arranged person shown in Fig. 6, that is the 2nd USB51,52 the 4th pin is ground connection, so, the 2nd USB51,52 the 4th pin is directly and data export connectivity port 3 or the screw 37,44 of audio-visual output connectivity port 4 is connected, with the purpose that is grounded.

By above description as can be known, two the 2nd USB51 that desire to add, 52 are arranged between first support body 34 or the space of second support body 41, so the specification of original PC99 is not made any change, so not only aspect cost, can meet fabricator's demand, and it also conforms to because of the specification with script on practicality, so the also suitable height of its compatibility.

Certainly, those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claims variation, the modification of the above embodiment.
