[0002] LED is becoming more and more popular in the market due to its energy saving and environmental protection. As the luminous efficiency of LED lighting continues to improve and the price continues to decrease, the luminous efficiency has completely surpassed the traditional energy-saving lamps and the price is gradually approaching the traditional energy-saving lamps. Therefore, it is unstoppable that LED lighting will gradually replace the traditional energy-saving lamps.

[0003] The existing LED lamp tube used for lighting includes a shell, a light-transmitting cover, an LED light source board, a driving power supply and two ends. The LED light source board is composed of a PCB circuit board and multiple LED lamp beads. The LED light source board is fixedly connected to the shell and the LED lamp beads are arranged opposite the light-transmitting cover. After the LED light source board is connected to the shell, the LED light source board is connected to the driving power supply, and then the light-transmitting cover is slidably matched with the shell, and then the two ends are installed. A terminal circuit board connected to the driving power supply is installed in the end, and a copper pin is installed outwardly on the end circuit board.

[0004] During the use of the above-mentioned LED lamp tube, since the light-transmitting cover and the shell are slidably matched and the two ends are limited by the end head, when the LED light source board is damaged, the end head needs to be disassembled to remove the light-transmitting cover, and finally the LED light source board can be repaired or replaced. However, the end head has a terminal circuit board installed in it, and the terminal limit plate is connected to the driving power supply. When the end head is disassembled, the circuit will be pulled, which is very likely to cause poor circuit contact or even circuit breakage, affecting the use. Summary of the invention
