Abstract

The invention discloses a driving power supply. The driving power supply comprises a power supply box and a circuit board arranged in the power supply box, the power supply box is provided with a mounting port, and the mounting port is packaged through an end cover assembly. The end cover assembly comprises an outer cover, a sealing plug, an inner cover and a wire, wherein the inner side of the outer cover is provided with a first sealing section which is inserted into the mounting port and attached to the inner wall of the power supply box, and the cover body is provided with a through first wire passing hole and a glue injection port; the sealing plug is positioned on the inner side of the outer cover and is mounted on the glue injection port; the inner cover is located in the mounting port and attached to the inner wall of the power supply box, a glue injection cavity is defined by the inner cover, the outer cover and the inner wall of the power supply box, and the inner cover is further provided with a second wire passing hole opposite to the first wire passing hole and a hollow column pressing the edge of the sealing plug; and one end of the wire penetrates through the first wire passing hole and the second wire passing hole and is electrically connected with the circuit board. The invention further discloses a glue injection method of the driving power supply.

Description

technical field [0001] The invention relates to the technical field of driving power supply, in particular to a driving power supply and a glue injection method for the driving power supply. Background technique [0002] Under the background of the current global energy shortage rising again, saving energy is an important issue we face in the future. In the field of lighting, LED lamps are more and more used in homes because of their high light extraction efficiency and good light-gathering performance. , In the field of commercial lighting, the 21st century will enter the era of new lighting sources represented by LEDs. LED drive power supply is an important part of LED lighting devices, generally including box body, circuit board and end cover assembly, end cover assembly can also be divided into input end cover assembly and output end cover assembly, generally arranged at both ends of the box body , the two ends of the package box are open. [0003] Among them, the end ...
