A line card fixing method for the output line of LED street lamp power supply

Abstract

The invention discloses a line card fixing method for an LED street lamp power supply output line. The invention utilizes a combined plastic line card, line card fixing screws, line card fixing plate, and fixing plate fixing screws to fix the power supply output line. The specific steps are: use the fixing plate fixing screws to fix the line card fixing plate on the lamp housing The position of the protruding screw fixing hole inside, press the square card feet of the combined plastic line card into the square hole of the line card fixing plate, open the line card cover, put the power output cable into the V-shaped groove, and cover the line card cover , The line card cover presses the power output line through the guide rod, screw the line card fixing screw into the line card screw fixing hole to fix the combined plastic line card, and the power output line is fixed. The structure of the lamp housing using the present invention does not require major changes, the production cost is not high, it is easy to implement, the operation is easy, and the power output line can be well fixed so that it will not be pulled after being shaken during transportation and use, avoiding Poor contact with the aluminum substrate pad.

Description

technical field [0001] The invention relates to a method for fixing a line card, in particular to a method for fixing a line card for an output line of a power supply of an LED street lamp. Background technique [0002] At present, most LED street lights have built-in power supplies. The output lines of the power supply are generally directly welded to the corresponding positive and negative pads of the aluminum substrate. Because the power supply output lines are long and not fixed in the middle, and there are usually large vibrations in the use environment of street lights, The output wire of the power supply will be pulled on the pad of the aluminum substrate, which will easily cause the pad to crack, the output wire to open or loosen, making the lamp unable to light up and use normally; in some LED street lights with an external power supply, the waterproof screw distance The welding pad is far away, and the internal power line is not fixed, and the same problem will occ...

[0002] At present, most LED street lights have built-in power supplies. The output lines of the power supply are generally directly welded to the corresponding positive and negative pads of the aluminum substrate. Because the power supply output lines are long and not fixed in the middle, and there are usually large vibrations in the use environment of street lights, The output wire of the power supply will be pulled on the pad of the aluminum substrate, which will easily cause the pad to crack, the output wire to open or loosen, making the lamp unable to light up and use normally; in some LED street lights with an external power supply, the waterproof screw distance The welding pad is far away, and the internal power line is not fixed, and the same problem will occur; although some lighting manufacturers have found this defect in actual production testing and customer feedback, they only use other temporary methods such as cable ties and glue to fix it. Mitigation, not fundamentally solved, let alone perfected from the production process, not enough attention
