Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of reliable and stable, holding time short and constant automatically can start the tool that electronic load carries out testing.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
Automatic startup electronic load of the present utility model carries out the tool tested, comprise casing and be placed in the circuit in casing, described circuit connects wire, biasing resistor and metal-oxide-semiconductor by many and forms, wherein, one end of first wire is connected to the grid of metal-oxide-semiconductor by biasing resistor, the other end one tunnel of the first wire is connected to the positive output end of tested power supply, and another road is connected to the positive input terminal of electronic load; Between the negative output terminal that second wire is connected to tested power supply and the negative input end of electronic load; The source electrode of described metal-oxide-semiconductor is connected with the positive control signal pins of electronic load by privates, and the drain electrode of metal-oxide-semiconductor connects with the negative control signals pin of electronic load.
Described metal-oxide-semiconductor adopts the switching tube of SVF4N60.
To connect and after described metal-oxide-semiconductor conducting 5ms, electronic load starts default test procedure automatically at tested power supply.
Described casing is made by bakelite material, and size is 150mm × 100mm × 75mm.
Compared with prior art, the utility model arranges one between tested power supply and electronic load can the switching tube of conducting automatically, make when charger or portable power source product flow through test step on a production line and connect this product power supply, sent the instruction of setup test to electronic load by the conducting of described switching tube, thus, described electronic load is made automatically to start the test job to this product according to the test procedure preset.The utility model can reduce the operation of test station, shortens the test duration, promotes testing efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model circuit connection diagram.
Embodiment
The tool that automatic startup electronic load of the present utility model carries out testing is made up of casing and the circuit board be placed in casing, described casing is made by bakelite material, its length × wide × height is 150mm × 100mm × 75mm, and this tool is fixed on by screw on the equipment of the test step of charger or portable power source flow production line.
As shown in Figure 1, circuit board is connected with many 20AWG wires, biasing resistor R1 and metal-oxide-semiconductor Q1 to form, wherein, one end of first wire is connected to the grid of metal-oxide-semiconductor Q1 by biasing resistor, the other end of the first wire is by nut fixed terminal, one tunnel is connected to the positive output end of tested power supply, and another road is connected to the positive input terminal of electronic load; Between the negative output terminal that second wire is connected to tested power supply and the negative input end of electronic load; The source electrode of described metal-oxide-semiconductor Q1 is connected with the positive control signal pins of electronic load by privates, and the drain electrode of metal-oxide-semiconductor connects with the negative control signals pin of electronic load.
Described metal-oxide-semiconductor Q1 preferably adopts the switching tube of SVF4N60, also can adopt the metal-oxide-semiconductor of other brands and model.
To connect and after described metal-oxide-semiconductor Q1 conducting 5ms, electronic load starts default test procedure automatically at tested power supply.
The course of work:
After tested power supply (namely described charger or portable power source) flows into test step and is energized, tested electric power output voltage is through biasing resistor R1 driven MOS pipe Q1 conducting, thus make the conducting over the ground of electronic load positive control signal pins, electronic load internal detection mechanism detects positive control signal pins over the ground after conduction 5ms, just thinks that starting test signal order sets up and instruction electronic load starts test job automatically according to pre-set programs.
