Specific embodiment

To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.

Now in conjunction with the drawings and specific embodiments, the present invention will be further described.

As depicted in figs. 1 and 2, the test device of computer on-off includes a wiring board, and wiring board is equipped with the first connection Device J1, the second connector J2, the first indicator light D1, the second indicator light D2 and buzzer BUZZ.First connector J1 is used for and electricity The connection of brain mainboard, it includes the first signal SPSW+, second signal that the first connector J1, which connects the signal being related to computer main board, SPSW-, third signal RST+, fourth signal RST-, the 5th signal PWRLED+, the 6th signal VBSLED-, the 7th signal HLED+ With the 8th signal HLED-；First signal SPSW+, second signal SPSW- are connected to the both ends of first switch S1；Third signal RST +, fourth signal RST- be connected to the both ends of second switch S2；The connection of the anode of 5th signal PWRLED+ and the first indicator light D1, The connection of the cathode of 6th signal PWRLED- and the first indicator light D1；The anode of 7th signal HLED+ and the second indicator light D2 connect It connects, the cathode connection of the 8th signal HLED- and the second indicator light D2.Second connector J2 with computer main board for connecting, and second It includes the 9th signal BUZZ+ and the tenth signal BUZZ-, the 9th signal BUZZ that connector J2, which connects the signal being related to computer main board, + anode the connection with buzzer BUZZ, the tenth signal BUZZ- are connected with the cathode of buzzer BUZZ.Wherein: first switch S1 is Power switch, second switch S2 are reset switch, and the first indicator light D1 is power supply indicator；Second indicator light D2 is hard disk instruction Lamp.

As shown in Figures 2 and 3, the first connector J1 is double 10 needle socket, and first row is respectively empty, the first signal SPSW +, second signal SPSW-, the 6th signal VBSLED- and the 5th signal PWRLED+, secondary series be respectively sky, third signal RST+, Fourth signal RST-, the 8th signal HLED- and the 7th signal HLED+.First connector J1 is equipped with empty foot, can effectively identify And prevent the double 10 pin plug anti-plug being attached thereto.When anti-plug occurs, at the 5th signal PWRLED+, the 7th signal HLED+ In vacant state, since second signal SPSW-, the 6th signal VBSLED-, fourth signal RST-, the 8th signal HLED- are in computer It is ground connection on mainboard, the 8th signal HLED- and fourth signal RST- connect at the both ends of first switch S1, second signal SPSW-, 6th signal VBSLED- connects at the both ends second switch S2, and the switch motion of first switch S1 and second switch S2 will not be to each letters Number any influence is generated, third signal RST+, the first signal SPSW+ are connect respectively in the first indicator light D1, the second indicator light D2 Cathode, the first indicator light D1, the anode of the second indicator light D2 are hanging, and the connection of the circuit will not be to third signal RST+, first Signal SPSW+ has an impact, and therefore, the anti-plug of double 10 pin plug is not in that power supply and ground are shorted phenomenon, does not have misplug wind Danger, can timely correction.

Second connector J2 be single 5 needle socket, the 9th signal BUZZ+, the tenth signal BUZZ- respectively with the second connector The first pin and the 5th pin connection.Single 5 pin plug connecting with the second connector J2, is dimensioned for plugging, be convenient for Operation, while empty foot is equipped between the 9th signal BUZZ+, the tenth signal BUZZ- can effectively prevent the 9th signal BUZZ+, the Ten signal BUZZ- are shorted.Buzzer BUZZ can not work because electric power polarity is reversed, and power supply will not occur and ground is shorted phenomenon, the Two connector J2 do not have misplug risk, can timely correction.

First switch S1 and second switch S2 generates trigger signal using touch-switch.For convenient for operation, first is opened It closes S1 and second switch S2 and selects large-sized touch-switch, such as touching out for 10mm × 10mm or 12mm × 12mm series It closes.

The test device of the computer on-off of the utility model is easy to use, is reasonably drawn according to the signal connected Foot distribution, has mistake proofing plugging function.

Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details On the utility model can be made a variety of changes, be the protection scope of the utility model.
