Description

Technical Field

[0001] The utility model relates to the technical field of reflection covers, in particular to a digital tube reflection cover structure. Background Art

[0002] The structure of the digital tube reflective cover usually adopts several forms such as reflective cover type, strip seven-segment type and monolithic integrated multi-digit type, and the structure of the digital tube reflective cover is mainly composed of a reflective cover and an LED circuit board assembly. The reflective cover is usually made of white plastic and has a seven-segment shell with a reflective cavity to reflect the LED light. The LED circuit board assembly is an electronic component used to fix and drive the LED chip. During the assembly process, it is necessary to connect silicon aluminum wire or metal leads to the LED chip and the printed circuit, then drip epoxy resin into the reflective cover, and then align and bond the printed circuit board with the chip to the reflective cover, and finally cure it.

[0003] A common reflective cover generally has a digital tube placement slot opened inside, and then the reflective cover is inserted on the surface of the PCB printed circuit board. However, during the digital tube glue filling and baking process, due to the heat of the colloid, there will be a large stress between the side cover and the colloid of the reflective cover. Due to the influence of stress, deformation and light leakage often occur. In addition, the traditional cover installation adopts bolt limiters, and tools need to be used to repeatedly rotate the screw during disassembly and assembly, which makes disassembly and assembly inconvenient and cannot meet the requirements of the use and installation of the reflective cover. Therefore, a digital tube reflective cover structure is proposed. Utility Model Content
