Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-5 This utility model provides an embodiment of a multi-layer composite sealed waterproof LED light string, comprising: a mounting plate 1, a first male plug 5 fixedly connected to one side of the mounting plate 1, an electrical control board 18 fixedly connected to the top of the mounting plate 1, a quick-connect assembly installed on the outer wall of the electrical control board 18 near the first male plug 5, a transparent protective cover 2 fixedly connected to the top of the mounting plate 1, a second female plug 7 fixedly connected to one side of the mounting plate 1, a contact plate 15 installed inside the second female plug 7, the rear side of the contact plate 15 fixedly connected to the outer wall of the electrical control board 18, and LED beads 4 installed on the top of the electrical control board 18. The plug 7 has a second male plug 14 installed inside. The second male plug 14 has a sliding plate 11 slidably connected inside. Multiple conductive contacts 12 are provided on the outer wall of the sliding plate 11. A spring 16 is fixedly connected between the inner wall of the second male plug 14 and the outer wall of the sliding plate 11. The spring 16 can keep the conductive contacts 12 in contact with the contact holes 17. A power cord 13 is installed on the rear side of the second male plug 14. Multiple contact holes 17 are opened inside the contact plate 15. A tail plug 3 is installed between the mounting plate 1 and the transparent protective cover 2. A rubber ring is provided on the outer ring of the tail plug 3. The contact holes 17 and the conductive contacts 12 are on the same horizontal plane.

[0025] Specifically, by inserting the second male plug 14 into the interior of the second female plug 7, the conductive contact 12 inside the second male plug 14 enters the contact hole 17 opened in the contact plate 15, thus connecting the power supply. The spring 16 keeps the conductive contact 12 in contact with the contact hole 17, ensuring electrical safety. The tail plug 3 on one side of the mounting plate 1 can ensure the waterproofness of the LED light string. When expansion is needed, the first male plug 5 is inserted into the interior of the first female plug 6 to improve expandability and achieve the growth of the LED light string.

[0026] Reference Figure 2 and Figure 3 The quick-connect assembly includes a conductive plate 8 fixedly connected to the outer wall of one side of the control board 18, a conductive block 10 fixedly connected to the top front side of the conductive plate 8, a bottom of the conductive plate 8 fixedly connected to the inside of the first male plug 5, a first female plug 6 fixedly connected to one side of the mounting plate 1, a conductive strip 9 installed inside the first female plug 6, a bottom of the conductive strip 9 fixedly connected to the outer wall of the control board 18, an outer wall of the conductive block 10 passing through the gaps in the conductive strip 9, and a sealing ring 19 fixedly connected to the outer wall of the first male plug 5.

[0027] Specifically, by inserting the first male plug 5 into the interior of the first female plug 6, the conductive block 10 on the conductive plate 8 comes into contact with the conductive strip 9. Then, through the sealing ring 19 installed on the outer wall of the first male plug 5 and the first female plug 6, the power is transmitted while the plug is waterproofed, which improves the overall waterproof level of the LED light string and enhances the safety of electricity use.

[0028] Working principle: When the second male plug 14 is inserted into the second female plug 7, its internal conductive contacts 12 maintain tight contact with the contact holes 17 of the contact plate 15 under the action of the spring 16. Power is transmitted to the control board 18 through the power line 13 and the conductive contacts 12, driving the LED beads 4 to emit light. The tail plug 3 between the mounting plate 1 and the transparent protective cover 2 forms a waterproof seal. During expansion, the first male plug 5 is inserted into the first female plug 6, and the conductive block 10 on the conductive plate 8 is embedded in the gap of the conductive strip 9 to complete the circuit conduction. The quick-connect assembly achieves rapid expansion while maintaining waterproof performance. The mounting plate 1, the transparent protective cover 2, and the tail plug 3, together with the spring 16 pressing design between the second female plug 7 and the second male plug 14, jointly ensure the waterproof safety and circuit stability of the light string.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
