Description

Technical Field

[0001] This utility model relates to the field of LED strip technology, specifically to an anti-surge LED strip plug. Background Technology

[0002] With the advancement of technology and the improvement of people's living standards, LED strip lights have become a commonly used lighting fixture, serving both decorative and illumination purposes. The LED strip plug is a crucial component, primarily connecting the strip to a power source. LED strip plugs generally include a control circuit board, which acts as a voltage regulator. However, existing LED strip plugs lack sufficient protection functions and have poor surge protection capabilities. Excessive voltage and current can pose safety hazards and result in a poor user experience. Therefore, to overcome the shortcomings of existing technology, it is necessary to improve it. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide a surge-resistant LED strip plug that is stable and safe to use.

[0004] This utility model is achieved through the following technical solution:

[0005] A surge-resistant LED strip connector includes a plug, which is connected to a driving power supply via a first connecting wire. The driving power supply is connected to an LED strip connector via a second connecting wire. The driving power supply contains a control circuit board, which includes a fuse FS and a varistor RV1. One end of the fuse FS is connected to the L terminal of the power supply, and the other end of the fuse FS is connected to the output terminal LO. The other end of the fuse FS is connected to the N terminal of the power supply via the varistor RV1. The N terminal of the power supply is connected to the output terminal NO.

[0006] Furthermore, the output terminal LO is connected to the positive terminal of the LED strip, and the output terminal NO is connected to the negative terminal of the LED strip.

[0007] Furthermore, a safety capacitor is connected in parallel with the varistor RV1.

[0008] Furthermore, the control circuit board has a positive input pad and a negative input pad on one side.

[0009] Furthermore, the other side of the control circuit board is provided with a positive output pad and a negative output pad.

[0010] Furthermore, the control circuit board is equipped with fuse pads.

[0011] Furthermore, the control circuit board is provided with resistor pads.

[0012] Furthermore, the rated power supply is 220V.

[0013] Furthermore, the rated current of the fuse FS is 15A.

[0014] Furthermore, the varistor RV1 is model RV471.

[0015] Compared to existing technologies, this invention connects one end of fuse FS to the L terminal of the power supply and the other end of fuse FS to the output terminal LO. The other end of fuse FS is connected to the N terminal of the power supply through a varistor RV1. Fuse FS provides overcurrent protection. When an overvoltage occurs between the two poles of varistor RV1, varistor RV1 clamps the voltage to a relatively fixed value, thereby protecting downstream electrical appliances. It provides overvoltage protection and voltage stabilization, has sufficient plug protection, provides stable protection when the voltage and current are too high, has strong surge resistance, eliminates safety hazards, prevents high temperature and spontaneous combustion, ensures personal safety, and provides a good user experience.
