Abstract

The invention discloses a driving end pin lamp tube with heat insulation function and an assembly process thereof, and relates to the technical field of pin lamp tubes. In the present invention, the driving end pin lamp tube is provided with elastic snap-on conduction mechanisms on both sides of the flexible circuit board, and the elastic snap-on conduction mechanism conducts current with the first contact pin and the second contact pin to form the first contact pin, The current path of the conduction mechanism, the power supply assembly, the flexible circuit board and the second contact pin is elastically clamped, which is more convenient to assemble. During use, the flexible circuit board has better stability through elastic clamping, and the luminous effect is stable; In order to achieve a good thermal insulation effect, the heat generated by the power supply components can be prevented from being conducted to the flexible circuit board. After the light diffusion thermal insulation coating is applied, the thermal insulation performance and light diffusion performance of the flexible circuit board are further increased, and the service life of the flexible circuit board is improved. ; The assembly method of plugging, pulling and clamping ensures the sealing performance and facilitates disassembly and maintenance.
