Increased safety glue filling drive box and lamps using the increased safety glue filling drive box

Abstract

An increased safety glue filling drive box, including an upper cover, a surrounding shell and a bottom shell, the surrounding shell includes a first open end and a second open end oppositely arranged, and the bottom shell is a frame with one end closed and one end open The bottom shell includes a bottom plate, the first opening end of the surrounding shell is sealed with the upper cover, the second opening end of the surrounding shell is fixedly connected with the bottom plate of the bottom shell, and there are a number of plugs perpendicular to the bottom plate of the bottom shell in the surrounding shell. Each two partitions form a driving board glue tank for placing the driving board, and the two ends of the bottom plate of the bottom case along the first direction are respectively provided with a number of holes for filling the wiring of the driving board. Glue wiring groove. The present invention only needs the glue filling thickness of the driving board glue filling groove to exceed the height of the driving board by more than 3 mm to meet the explosion-proof requirements; and the glue filling thickness of the wiring glue filling groove can be smaller than the glue filling thickness of the driving board glue filling groove, which not only satisfies the Explosion-proof requirements, and save the cost of glue filling. The invention also provides a lamp using the safety-increasing glue filling drive box.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a safety-increasing glue-filling drive box and a lamp using the safety-enhancing glue-filling drive box. Background technique [0002] The drive box installed inside various increased safety explosion-proof lighting fixtures is responsible for the dual functions of protecting the drive circuit board and accommodating glue filling. GB / T 3836.3 stipulates that the safety-increasing circuit needs to be filled with epoxy colloid that exceeds the height of the circuit board by more than 3mm, and can dissipate heat reliably. [0003] At present, the safety-increased explosion-proof drive boxes on the market are all simple box-shaped structures made of sheet metal or polycarbonate. Generally, the peripheral length, width, and height dimensions are individually customized according to the size of the drive circuit board, and then filled with epoxy glue. Finally add the lid. The safety-increased ex...
