DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 - Figure 4 , a three-wire continuous LED light string group shown in the figure includes a three-wire conductor 1 and a plurality of LED lamp bodies 2 electrically connected to the three-wire conductor 1, and also includes a connecting male plug 3 and a connecting female plug 4 installed at both ends of the three-wire conductor 1, the connecting male plug 3 and the connecting female plug 4 are adapted to each other, and a locking mechanism 5 is installed on the outer side of the connecting male plug 3 and the connecting female plug 4, and the locking mechanism 5 makes the connecting male plug 3 and the connecting female plug 4 docking stable; and a protective rubber sleeve 6 fixing the tail ends of the connecting male plug 3 and the connecting female plug 4, a protective unit 7 connected to the three-wire conductor 1 is arranged in the protective rubber sleeve 6, and the protective unit 7 is connected to the locking mechanism 5;

[0033] In this solution, the conventional connecting male plug 3 and connecting female plug 4 are improved. After the connecting male plug 3 and the connecting female plug 4 are docked, the personnel buckle the locking mechanism 5 to make the connecting male plug 3 and the connecting female plug 4 docked stably. At the same time, after the locking mechanism 5 is docked, it will drive the corresponding movement of the protection unit 7, so that the three-wire conductor 1 at the protective rubber sleeve 6 is pulled from a straightened state to a bent state, so that when the three-wire conductor 1 is accidentally pulled subsequently, the bent three-wire conductor 1 at the protective rubber sleeve 6 will deform from the bent state to the straightened state, which has a certain anti-pulling buffer effect, avoiding accidental pulling, resulting in loosening of the three-wire conductor 1 and the connecting male plug 3 and the connecting female plug 4.

[0034] For further information, see Figure 3-Figure 5 The locking mechanism 5 includes a docking ring 8 and a rotating ring 9. The outer sides of the connecting male plug 3 and the connecting female plug 4 are respectively provided with a sliding ring groove 10 and a sliding ring groove 2 11. The docking ring 8 is slidably sleeved on the outer side of the sliding ring groove 10. The outer side of the sliding ring groove 2 11 is slidably sleeved with a moving ring 12. The rotating ring 9 is rotatably connected with the moving ring 12. The inner side of the rotating ring 9 and the outer side of the docking ring 8 are provided with threaded grooves 13 that match each other.

[0035] In order to enable the docking ring 8 and the movable ring 12 to move stably in the sliding ring groove 10 and the sliding ring groove 2 11, a plurality of limit strips 14 are fixed on the outer walls of the sliding ring groove 10 and the sliding ring groove 2 11, and the docking ring 8 and the movable ring 12 are slidably connected to the plurality of limit strips 14.

[0036] In this solution, after the male plug 3 is connected to the female plug 4, the person pinches the docking ring 8 with one hand and the rotating ring 9 with the other hand, and then moves the docking ring 8 and the rotating ring 9 toward each other for docking. After docking, the person rotates the rotating ring 9 so that the corresponding threads of the docking ring 8 and the rotating ring 9 are docked to achieve locking.

[0037] For further information, see Figure 3 , Figure 7 and Figure 8 The protection unit 7 includes a plurality of traction ropes 19 and two semicircular clamps 20. The two semicircular clamps 20 are respectively arranged at the outer ends of the protective rubber sleeve 6 connecting the male plug 3 and the female plug 4, and are sleeved on the outside of the three-wire conductor 1. The semicircular clamps 20 are fixed to the three-wire conductor 1 by tightening screws. A plurality of traction ropes 19 are fixed to the outside of the two semicircular clamps 20. The other end of the traction rope 19 slides through the protective rubber sleeve 6 and is fixed to the outer walls of the docking ring 8 and the moving ring 12 respectively. Through the movement of the moving ring 12 and the docking ring 8, the semicircular clamps 20 and the three-wire conductor 1 are driven to move accordingly, so that the three-wire conductor 1 is bent to form a buffering shape. The traction rope 19 is an elastic rope.

[0038] Among them, the outer walls of the tail ends of the connecting male plug 3 and the connecting female plug 4 are both installed with a wire shaft 21 adapted to the traction rope 19, and the outer walls of the connecting male plug 3 and the connecting female plug 4 are both fixed with a wire block 22 adapted to the traction rope 19. The designed wire shaft 21 and the wire block 22 cooperate with each other, so that the traction rope 19 has a certain moving trajectory, so that the docking ring 8 and the moving ring 12 can stably pull the traction rope 19 to move when moving.

[0039] In order to facilitate the rotation of the rotating ring 9 by personnel, an anti-slip strip 23 is fixed on the outer wall of the rotating ring 9 .

[0040] The principle of the protection unit 7 for buffering and protecting the three-wire conductor 1 is as follows: after the personnel pinch the docking ring 8 and the rotating ring 9 to make them threadedly docked, the traction rope 19 will be driven to pull the corresponding semicircular clamp 20, so that the three-wire conductor 1 fixed with the semicircular clamp 20 is pulled. After the docking ring 8 and the rotating ring 9 are threadedly sleeved, the three-wire conductor 1 in the protective rubber sleeve 6 will be pulled from a straight line to a curved state to form a buffer shape. After the three-wire conductor 1 is subsequently pulled, the curved three-wire conductor 1 will change from a curved state to a straight line state, which has a certain buffering and protective effect, and prevents the three-wire conductor 1 from being pulled. The joint between the male plug 3 and the female plug 4 will be loosened, thereby improving the docking stability and avoiding the situation where power outages are caused by pulling.

[0041] It should also be noted that the protective rubber sleeve 6 is made of elastic rubber. After the male plug 3 is disconnected from the female plug 4, the elasticity of the protective rubber sleeve 6 itself will drive the docking ring 8 and the movable ring 12 to move correspondingly from the sliding ring groove 10 and the sliding ring groove 2 11, so that the three-wire conductor 1 is restored from the bent state to the straightened state, which is convenient for the next docking.

[0042] In this solution, a method for installing and using a three-wire continuous LED light string group includes a three-wire continuous LED light string group. The method for installing and using the light string is as follows:

[0043] S1. According to the use requirements, select a corresponding number of LED light string segments, connect them in sequence by connecting the male plug 3 and the female plug 4, realize conduction, and complete the conduction with the control terminal;

[0044] S2. When the male connector 3 and the female connector 4 are plugged in, the locking mechanism 5 is buckled to drive the protection unit 7 to retract, thereby protecting the joint between the three-wire conductor 1 and the male connector 3 and the female connector 4;

[0045] S3, the control terminal completes the power connection and turns on the power, thus completing the overall power-on of the LED combination light string;

[0046] S4, the control terminal inputs the command signal through the button, enters the address burning mode through the control module, completes the signal input to the control chip in each LED lamp body 2 in the LED combination lamp string, and completes the code writing and burning;

[0047] S5. The control terminal realizes the lighting control of the LED combination light string.

[0048] Example 2: Please refer to Figure 4 and Figure 5 This embodiment further explains the first embodiment, and the difference lies in that the connecting male plug 3 and the connecting female plug 4 are optimized to make them more stable after docking.

[0049] Specifically, a plurality of positioning holes 15 are provided on the connecting male plug 3, and positioning balls 24 are placed in the positioning holes 15. The positioning balls 24 move in the positioning holes 15 without leaving the positioning holes 15. A positioning opening 16 matching the positioning hole 15 is provided on the outer wall of the jack terminal of the connecting female plug 4. After the connecting male plug 3 is docked with the connecting female plug 4, the positioning balls 24 abut against the positioning opening 16.

[0050] In this solution: after the female connector 4 and the male connector 3 are docked, the positioning ball 24 in the positioning hole 15 moves in the positioning hole 15, which will not affect the connection between the female connector 4 and the male connector 3. After the connection, the docking ring 8 moves in the sliding ring groove 10 through the movement of the docking ring 8. After the docking ring 8 moves through the positioning hole 15, it will squeeze the positioning ball 24, so that the positioning ball 24 is against the positioning port 16, thereby achieving a locking effect between the female connector 4 and the male connector 3.

[0051] Example 3: Please refer to Figure 6 and Figure 7 This embodiment further illustrates other embodiments, and the difference lies in that the connecting male plug 3 and the connecting female plug 4 are optimized.

[0052] Specifically, a positioning plate 17 is provided in the connecting male plug 3, and a positioning groove 18 compatible with the positioning plate 17 is provided on the socket terminal of the connecting female plug 4. The design of the positioning plate 17 and the positioning groove 18 allows correction to be made when the connecting male plug 3 and the connecting female plug 4 are plugged in, making the plugging more accurate and smooth.
