Epoxy potting technology of safety-increasing epoxy potting driving box, safety-increasing epoxy potting driving box and lamp

Abstract

A safety-increasing epoxy potting driving box comprises an upper cover, an enclosing shell and a bottom shell, wherein the enclosing shell comprises a first opening end and a second opening end, the first opening end and the second opening end are oppositely arranged, the bottom shell is of a frame structure with one end closed and the other end open, the bottom shell comprises a base plate, the first opening end of the enclosing shell is in seal fit with the upper cover, the second opening end of the enclosing shell is fixedly connected with the base plate of the bottom shell, a plurality of partition plates vertically inserted in the base plate of the bottom shell are arranged in the enclosing shell, a driving plate epoxy potting groove used for containing a driving plate is formed between each two partition plates, and a plurality of connection wire epoxy potting grooves used for potting epoxy to the connection wires of the driving plates are arranged at two ends of the base plate of the bottom shell along the first direction of the base plate. According to the safety-increasing epoxy potting driving box, epoxy potting thickness of the driving plate epoxy potting grooves only needs to be at least 3 mm larger than height of the diving plates, the epoxy potting thickness of the connection wire epoxy potting grooves can be smaller than the epoxy potting thickness of the driving plate epoxy potting grooves, anti-explosion requirements are met, and epoxy potting cost is saved. The invention further relates to a epoxy potting technology of the safety-increasing epoxy potting driving box and a lamp using the safety-increasing epoxy potting driving box.

Description

technical field [0001] The field of lamps of the present invention particularly relates to a glue filling process of an increased safety glue filling drive box, an increased safety glue filling drive box used in the glue filling process, and a lamp using the increased safety 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 si...
