[0017] Reference Figure 5 The LED lamp strip 1 comprises a flexible circuit board 11, a plurality of LED lamp beads 12 mounted on the flexible circuit board 11, a plurality of live terminals 13 arranged on the flexible circuit board 11 and a flexible outer skin 14 wrapping the flexible circuit board 11. The circuit board 11 comprises a circuit layer and a back insulating film and a front insulating film arranged on both sides of the circuit layer respectively, the circuit layer is provided with a power circuit and a signal circuit, the front insulating film is provided with a window corresponding to the position of the circuit, and the live terminal 13 is a soldering tin in the window and in electrical contact with the power circuit and the signal circuit.

[0018] Reference Figures 3 to 5 The power connector 2 is made of hard plastic and comprises a body 20, the body 20 is provided with a power line 21 at one end and a lamp strip groove 22 at the other end. The power line 21 can be directly connected to a household power line, or a plug 23 can be arranged to connect to a socket. The lamp strip groove 22 is formed by a bottom plate 222 and two opposite side plates 221 extending from the body 21. The side plates 221 and the bottom plate 222 are disconnected from each other in the lamp strip groove 22 except that the body 20 is a common connection point, that is, the three can be independently bent and deformed. The side plate 221 and the lamp strip groove 22 take the end close to the body 20 as the inner end and the end away from the body 20 as the outer end. The thickness of the outer end of the side plate 221 is greater than that of the inner end, and the specific embodiment includes two kinds, one of which is as shown in Figure 3 The inner side surfaces 22b of the two side walls 221 are parallel to each other, and the outer side surfaces 22a thereof are inclined to each other; the other is as shown in Figure 4As shown, the outer sides 22b of the two side walls 221 are parallel to each other, and the inner sides 22b of the two side walls 221 are inclined to each other. The side walls 221 and the inner side of the bottom wall 222 are provided with sharp anti-skid teeth 25 towards the inner end of the lamp strip groove 22. The body 20 is further provided with at least two insertion pins 24, one end of the insertion pin 24 extending into the lamp strip groove 22, and the other end being electrically connected with the power cord 21. The insertion pin 24 can also be more than two in the LED lamp strip requiring transmission of control signals. The body 20 is provided with a step 26 near the lamp strip groove 22.

[0019] With reference to Figures 2 to 8 The fastening sleeve 3 is made of hard plastic, and includes two side walls 31 parallel to each other, and an upper wall 32 and a lower wall 33 parallel to each other. One end of the fastening sleeve 3 is provided with a baffle 34 capable of clamping the step 26 of the power connector 2 or the end of the lamp strip groove 22, and the other end is a straight-through end. The two side walls 31 of the fastening sleeve 3 are in interference fit with the two side walls 221 of the lamp strip groove 22, and when the fastening sleeve 3 is sleeved on the lamp strip groove 22, the two side walls 31 of the fastening sleeve 3 press the two side walls 221 of the lamp strip groove 22, so that the outer end width L1 of the lamp strip groove 22 is smaller than the inner end width L2 of the lamp strip groove 22. In this way, the fastening sleeve 3 can be sleeved from the outer end or the inner end of the lamp strip groove 22, and the installation degree of freedom is higher. Of course, the two side walls 31 of the fastening sleeve 3 can also be arranged to be inclined to each other, and the outer end and the inner end of the two side walls 221 of the lamp strip groove 22 have equal thicknesses, so that the outer end spacing L1 of the lamp strip groove 22 is also smaller than the inner end spacing L2 of the lamp strip groove 22 after the fastening sleeve 3 is sleeved on the lamp strip groove 22.

[0020] With reference to Figure 1 , Figure 3 and Figure 7 The assembly method of the utility model is as follows: first, as shown in Figure 3 , the fastening sleeve 3 is sleeved on the power cord 21, and the straight-through end faces the lamp strip groove 22; or the fastening sleeve 3 is sleeved on the LED lamp strip 1, and the straight-through end faces the end of the LED lamp strip 1; then the LED lamp strip 1 is aligned with the insertion pins 24, and is inserted into the bottom of the lamp strip groove 22 from the end opening of the lamp strip groove 22, at this time, the two insertion pins 24 are inserted into the LED lamp strip 1 from the end of the LED lamp strip 1 between the outer skin 14 and the circuit board 11, and are electrically connected with the two contact terminals 13 on the circuit board 21 respectively; finally, the fastening sleeve 3 is sleeved into the lamp strip groove 22 until the baffle 34 of the fastening sleeve 3 abuts against the step 25 of the body 20, or the baffle 34 of the fastening sleeve 3 abuts against the outer end face of the lamp strip groove 22.

[0021] With reference to Figure 7The LED lamp strip is connected with the power connector. Due to the interference fit between the two side walls 31 of the fastening sleeve 3 and the two side plates 221 of the lamp strip groove 22, and the thickness of the outer end of the side plate 221 is greater than that of the inner end, the two side walls 31 of the fastening sleeve 3 press the two side plates 221 of the lamp strip groove 22, so that the outer end width L1 of the lamp strip groove 22 is less than the inner end width L2. In both cases, the flexible outer skin 14 of the LED lamp strip 1 is elastically deformed after being pressed by the two side plates 221 of the lamp strip groove 22, and the deformation of the outer skin 14 at the outer end of the lamp strip groove 22 is greater than that at the inner end. In this way, the LED lamp strip 1 is equivalent to being clamped in the lamp strip groove 22, and the connection strength between the LED lamp strip 1 and the lamp strip groove 22 is high, and can withstand a large pulling force. Even, since the side wall 221 is made of hard material, the sharp anti-skid teeth 25 on the side plate 1 can pierce the outer skin 14 of the LED lamp strip 1, which can increase the friction and further improve the connection strength. The upper wall 32 and the lower wall 33 of the fastening sleeve 3 are clamped on the upper and lower surfaces of the lamp strip groove 22 to provide support for the bottom plate 222, so that the live terminal 13 of the LED lamp strip 1 maintains close electrical contact with the pin 24. Since the power connector 1 and the fastening sleeve 3 do not have repeated folding parts, they can be made of hard plastic, and the fastening sleeve 3 has a closed ring structure and good integrity, so the fastening force and durability are better.

[0022] Embodiment 2. The structure of this embodiment is mostly the same as that of embodiment 1, and the following mainly describes the different parts, and the parts not described can refer to embodiment 1. Referring to Figure 4 , the body 20 is provided with two mounting holes 27 leading to the lamp strip groove 22, and a conductive sleeve 28 is arranged in the mounting hole 27. The sleeve 28 is inserted into the mounting hole 27 towards the lamp strip groove 22, and the other end is electrically connected with the power cord 11. The two pins 24 are inserted on the fixed part 241, and the fixed part 241 fixes the interval of the pins 24, so that one end of the two pins 24 has the same interval as the two live terminals 23 on the LED lamp strip, and the other end has the same interval as the two sleeves 28. The installation method of this embodiment is different from that of embodiment 1. First, one end of the pin is inserted into the end of the LED lamp strip, and the other end of the pin is inserted into the sleeve 28 during the process of inserting the LED lamp strip into the lamp strip groove 22. Since the sleeve 28 is inserted into the mounting hole 27, even if the power cord 21 is connected to the mains during the installation process, there is no risk of electric shock, and the construction safety index is higher.

[0023] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several deformations and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
