[0002] A constant current driver is an electronic device used to control the current flowing through a load. It is usually used in industries such as LED lighting, drive power supplies or switching power supplies. Its function is to ensure that the load obtains a stable current and is not affected by changes in power supply voltage or load changes, thereby ensuring stable operation of the load.

At the same time, the input line end cover of the existing driver is usually fixed to the housing by bolts. When the input line needs to be operated, a tool is required to remove the end cover, and the end cover cannot be quickly disassembled, affecting the normal use of the constant current driver.
