Description

Technical Field

[0001] The utility model specifically relates to a functional testing device for a voltage - doubling rectifier circuit board. Background Art

[0002] The voltage - doubling rectifier circuit board is a circuit board used for voltage - doubling rectification of an electric flame stove. Usually, more than 18 plasma torches are installed in a household electric flame stove, and even more than 150 plasma torches are installed in a commercial electric flame stove. The plasma torches correspond one - to - one with the voltage - doubling units of the circuit board, and each single voltage - doubling unit independently provides voltage - doubling rectified voltage for the corresponding plasma torch.

[0003] In the production workshop, the testing of the voltage - doubling rectifier circuit board is very important. In the prior art, generally, a test pen connected to a buzzer is used manually to click and test each voltage - doubling unit on the circuit board one by one. Such a process has low efficiency and also increases the labor cost. Content of the Utility Model

At least 18 test needles are arranged on the test board, and the test needles correspond one - to - one with the output ends of N voltage - doubling units on the circuit board to be tested. The prompting board is provided with prompting lights equal in number to the test needles. A single prompting light is electrically connected to the lower end of the corresponding single test needle, and the other extreme of the prompting light is electrically connected to the negative pole of the power supply box.

[0006] Preferably, the test needles pass through the through - holes opened at the output ends of the corresponding voltage - doubling units one by one.

[0007] Preferably, the circuit board to be tested is close to the test board so that the circuit board to be tested is installed on the test board, and the test needles are electrically connected to the output ends of the corresponding voltage - doubling units.

[0008] Preferably, the positive pole of the power supply box is electrically connected to the positive - pole input end of the circuit board to be tested.

[0009] Preferably, the power supply box is also provided with a DC power switch.

[0010] Compared with the prior art, the advantages of the utility model are as follows: By arranging N test needles corresponding one - to - one with the output ends of the voltage - doubling units on the test board, the utility model can simultaneously test the performance of all voltage - doubling units of the circuit board at one time, improving the testing efficiency.
