Technical field
The utility model power supply test technical field more particularly to a kind of power supply test connector and its system.
Background technology
Power supply is the device that power is provided to electronic equipment, also referred to as power supply unit.Computer power supply is mounted to host
Closing individual components in case, its effect are that alternating current is converted to 5V, 12V, -12V, 3.3V by switching mode power supply transformer
Etc. steady dc voltages, so that mainboard in mainframe box, hard disk and other all parts use.
Whether size, electric current and the voltage of power are stablized, and will directly affect computer operation performance and used life.
It can be seen that the quality of a power supply is most important for a product, so the test for power supply is also very important.
Under normal circumstances, when testing power supply, the output loading to power supply is needed, this just needs the connection simulation in the output of power supply negative
The test equipment of load, such as electronic load, but the output terminal of power supply is all standard interface, and has a variety of different voltage outputs,
It needs to connect electronic load respectively, and these standard interfaces are not suitable for each electronic load, these standard interfaces can not thus
Directly it is connect with electronic load.
To solve the above-mentioned problems, there are two types of schemes at present：A kind of is the standard interface for removing power output end, will be exported
Signal wire be connected to electronic load.But standard interface is removed in test, if being loaded on after the completion of test so that standard
Interface repeated disassembled and assembled has not only been lost standard interface, has also destroyed power supply；Even if the standard interface removed is not loaded on, tearing open
Also power supply is destroyed during removing so that power supply normally or can not be used effectively.Another kind is by the standard of power output end
Interface is connected on corresponding interface, then from welding signal line on corresponding interface, is then connected to electronic load.But this
Sample according to different electronic loads, needs to select corresponding interface every time, and welding operation is repeated, and both wastes time, and
Welding operation damages to test man's body, and will appear problem of faulty soldering in the welding process then to the validity of test
It impacts.
