Description

Technical Field

[0001] The utility model relates to the field of testing devices, in particular to a transient voltage suppression diode testing device. Background Art

[0002] A diode tester is an instrument used to test the electrical properties of a diode. It usually consists of a power supply section and a measuring section. When testing a diode, the power supply section provides a constant voltage or current, while the measuring section measures the diode's voltage, current, reverse leakage current and other parameters. When using a diode tester, you first need to correctly connect the diode to be tested to the tester, and then, by operating the control buttons or knobs on the tester, you can select different test modes and parameter settings.

[0003] When performing wiring test on a diode, a connecting wire is usually used to connect to the terminal on the diode tester, and then the conductive clip at one end of the connecting wire is connected to the pin on the diode. Then the diode tester can be used directly to test the diode.

[0004] However, since the pins of the diode are usually located on the same side and the pin spacing on the diode is moved, the conductive clip at one end of the connecting wire is directly connected to the pins on the diode. When the diode and the conductive clip connected to it are placed on a table, the two conductive clips connected to the diode may contact and short-circuit, which makes it inconvenient to stably install and connect the pins of the diode by plugging.
