Embodiment 7
In the present embodiment, the temperature monitoring module is provided with buzzer warning device.Remaining technical side of the present embodiment Case is consistent with embodiment 1, and the technical scheme adopted by the present embodiment is also applied for remaining embodiment.
Circuit theory of the present utility model is as follows:
After the test interface of power supply adaptor and detection instrument is attached, test interface plate, metalfilmresistor, electricity A complete loop being constituted between flow table, therefore power supply adaptor activating voltage output after detecting load, now voltmeter can Show the output voltage of adapter.
After open type self-resetting switch is pressed, 7 pin of the time relay obtain 12V and power, and start timing, and 8 pin Connect with 5 pin, thus 5 pin also obtain 12V and power and export to 14 pin of auxiliary reclay;
14 pin of auxiliary reclay are obtained after 12V powers, 12 pin and the connection of 8 pin, and 12V is powered and exported to 12 pin by 8 pin, Exported by 12 pin to 7 pin of the time relay again, now the total two-way 12V of 7 pin of the time relay powers, all the way through Self-resetting Switch, all the way through auxiliary reclay.
The simultaneously 9 pin and 5 pin connection of auxiliary reclay, the output current of power supply adaptor flow through simultaneously metalfilmresistor and High-power aluminum casing resistor, as the resistance of aluminum casing resistor is very low, the output current of power supply adaptor becomes big, realizes the inspection of performance Survey.
Open type self-resetting switch finger release after can disconnecting circuit connection, the now power supply of the time relay from 12 pin of auxiliary reclay, while 5 pin of the power supply of auxiliary reclay from the time relay, be achieved in the time relay and The interlocking of auxiliary reclay, the time relay have continued power to be able to normal timing.
After time relay timing expires, 8 pin and 5 pin disconnect, and auxiliary reclay disconnects 12 pin and 8 pin after not powering Connection, the time relay also power-off therewith, now circuit enter standby mode, wait actuation of keys next time.
The radiator fan adopted by the utility model is that outer air draft form, fresh air are entered by the air vent for detecting tool bottom Tool interior, flows through load resistance and takes away heat, then discharged by radiator fan.
Operation principle of the present utility model is as follows:
After detection instrument enters holding state, it would be desirable to which the magetic indicator joint of the power supply adaptor of test is connected to panel and connects Mouthful, after connection power supply adaptor, the output voltage of voltmeter meeting display adapter, such as voltage is 0 or nominal less than adapter Voltage, can determine that power supply adaptor dysfunction, and when output voltage is less than 11V, voltmeter can flash and point out with alarm sound Electric voltage exception.
Pen-down detection time switch, proceeds by power supply adaptor band and carries test.After starting band load test, ammeter can show Show the output current of adapter, such as output current is 0 or the nominal current less than adapter, can determine that power supply adaptor function not Good.The testing time can be set as 3 minutes, during this period, when such as electric current is less than 2.5A, ammeter can flash and carry with alarm sound Show current anomaly, can determine that adapter unstable properties.
After band load test terminates, detection instrument is closed.After expiring during tester, detection instrument can cut out the electric current of adapter Output, now voltage still shows afterwards, but electric current is 0.
The above is only preferred embodiment of the present utility model, rather than a limitation;Although it should be pointed out that with reference to upper State each embodiment to be described in detail the utility model, it will be understood by those within the art that, which still can be with Technical scheme described in the various embodiments described above is modified, or equivalent is carried out to which part or all technical characteristic and replace Change;And these modifications and replacement, do not make the essence of corresponding technical scheme depart from each embodiment technical scheme of the utility model Scope.
