Description

Technical Field

[0001] The utility model relates to the technical field of light strip connectors, in particular to a universal fast light strip connector. Background Art

[0002] LED light strips are LEDs assembled on a strip-shaped FPC (flexible circuit board) or PCB hard board, and are shaped like a strip. LED light strips are popular with consumers for their long service life, energy saving, and environmental protection, and are increasingly widely used. When using LED light strips, they need to be connected through LED light strip connectors.
