[0019] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] The following describes an embodiment of the present invention based on its overall structure.

[0021] A splicable LED light strip, as shown in Figures 1-5, includes a first connector 1 and a second connector 2. A snap-fit ​​mechanism is provided inside the first connector 1 to connect the first connector 1 and the second connector 2.

[0022] The engaging mechanism includes a mounting block 204 and a mounting slot 202. The mounting block 204 is located inside the mounting slot 202. A sliding slot 205 is provided on one side of the mounting block 204 and one side of the mounting slot 202. A return spring 206 is installed inside the sliding slot 205. The end of the return spring 206 is connected to a limit plate 203 that cooperates with the sliding slot 205. The two limit plates 203 are symmetrical to each other, and the cross-sections of the two limit plates 203 are both trapezoidal.

[0023] The two sets of limit plates 203 with trapezoidal cross sections conflict with each other. Under the action of the return spring 206, when the mounting block 204 is inserted into the mounting groove 202, the two limit plates 203 contact each other, preventing the first connector 1 and the second connector 2 from being disconnected.

[0024] It should be noted that the second connector 2 is placed into the first connector 1 from top to bottom, and the connection between the first connector 1 and the second connector 2 is completed by cooperating with the snap-fit ​​mechanism.

[0025] See also Figure 2 、 Figure 3 and Figure 5 The locking mechanism also includes a card plate 104, a cavity 103 that cooperates with the card plate 104, a card slot 105 is provided on one side of the card plate 104, and a card block 106 that cooperates with the card slot 105 is provided on one side of the cavity 103. The cross-sections of the card block 106 and the card slot 105 are both obtuse triangles. The first joint 1 includes a base plate 101 and a cover plate 102. A connecting cavity is provided between the base plate 101 and the cover plate 102. The mounting blocks 204 are located on both sides of the connecting cavity. The card plate 104 is fixedly connected to the cover plate 102. The cavity 103 is located on one side of the base plate 101, and the cover plate 102 is rotatably connected to the base plate 101.

[0026] Because the material of the card plate is plastic with a certain degree of deformability, the card block 106 with an obtuse triangle cross section can enter the card slot 105. At this time, one end of the second connector 2 enters the interior of the connecting cavity. At this time, the cover plate 102 and the bottom plate 101 are closed to engage the second connector 2 to complete the connection.

[0027] It can be understood that by rotating the cover 102, the block 106 leaves the slot 105, and then the plug 201 in the second connector 2 is placed into the interior of the connecting cavity, and then the cover 102 is rotated so that the card plate 104 enters the interior of the cavity 103. At this time, the block 106 enters the interior of the slot 105, completing the connection between the first connector 1 and the second connector 2.

[0028] See also Figure 2 and Figure 3 A light strip 3 is connected between the first connector 1 and the second connector 2. The second connector 2 includes a plug 201. The mounting grooves 202 are located on both sides of the bottom of the plug 201. The two mounting grooves 202 correspond to two mounting blocks 204, forming a plug-in connection between the two sets of LED light strips.

[0029] It should be noted that when the plug 201 is placed inside the connecting cavity, the two mounting blocks 204 enter the two mounting grooves 202. At this time, under the action of the return spring 206, the symmetrical limit plates 203 conflict with each other, and then the cover plate 102 is pressed to complete the connection between the first connector 1 and the second connector 2. At the same time, when the cover plate 102 is rotated closed, the two conflicting limit plates 203 squeeze the return spring inward, so that the plug 201 fully fits the connecting cavity. When the plug 201 is pulled outward, the plug 201 cannot leave the connecting cavity, thereby making the connection effect between the first connector 1 and the second connector 2 better.
