Description

Technical Field

[0001] This utility model relates to the field of electronic component manufacturing technology, and in particular to a test fixture for online testing of the limit voltage of electronic components. Background Technology

[0002] Online limit voltage testing of electronic components can expose design flaws in advance, preventing system crashes or safety accidents caused by field failures. This is especially important in high-reliability fields such as automotive electronics and power grid equipment.

[0003] Test fixtures for online testing of the limit voltage of electronic components can achieve the purpose of safely applying high voltage and accurately measuring it, protecting the test equipment and realizing real-time acquisition of parameters under real working conditions.

[0004] However, in the existing technology, with the development of technology and the expansion of application scenarios, the voltage required for high-voltage storage of some product functions is getting higher and higher, while the physical volume is getting smaller and smaller. This results in insufficient physical distance between the product and the high-voltage test, causing physical creepage or ionization discharge in the air. Utility Model Content

[0005] The purpose of this utility model is to provide a test fixture for online testing of the limit voltage of electronic components. It aims to solve the technical problem in the prior art that, with the development of technology and the expansion of application scenarios, the voltage required for high-voltage storage of some products is getting higher and higher, while the physical volume is getting smaller and smaller. This causes the physical distance of some products to be insufficient during high-voltage testing, resulting in physical creepage or ionization discharge in the air.
