[0032] Embodiment 1

[0033] Please refer to Figures 1 to 4, Embodiment 1 of the utility model is: a waterproof soft light strip, comprising an end assembly and a flexible protective strip 1 with a flexible light strip 6 embedded therein, the end assembly comprising an outer shell 2 and a cable 3 connected to an electrical connector 4, the outer shell 2 is connected to the flexible protective strip 1, the end of the cable 3 away from the electrical connector 4 is electrically connected to the flexible light strip 6, the inner space of the outer shell 2 comprises a connected inlet portion 21 and a potting portion 22, the cross-sectional size of the potting portion 22 is larger than the cross-sectional size of the inlet portion 21, one end of the flexible protective strip 1 extends into the potting portion 22 via the inlet portion 21, and the end of the flexible protective strip 1 is provided with a potting through hole 11, the two ends of the potting through hole 11 are respectively connected to the potting part 22; the outer shell 2 is provided with a potting port 23 for pouring sealant into the potting part 22, and the sealant in the potting part 22 forms a glue column 5 in the potting through hole 11 after solidification, and the outer shell 2 includes a first shell 24 and a second shell 25, the first shell 24 is provided with an elastic card block 241, and the second shell 25 is provided with a card hole 251 matched with the elastic card block 241, and the card hole 251 is connected to the outer surface of the outer shell 2, and the first shell 24 and the second shell 25 are respectively provided with a card tooth 26 for clamping the flexible protective strip 1.

[0034] Since the cross-sectional dimension of the potting portion 22 is larger than that of the inlet portion 21 , the solidified sealant cannot be pulled out from the end of the inlet portion 21 away from the potting portion 22 , and the solidified sealant is limited by the variable diameter structure at the connection point between the potting portion 22 and the inlet portion 21 .

[0035] Optionally, the cross-sections of the first shell 24 and the second shell 25 are respectively in a concave shape. The second shell 25 is provided with a plurality of the clamping holes 251, and correspondingly, the first shell 24 is provided with a plurality of clamping blocks 241 corresponding to the clamping holes 251. In this embodiment, the potting port 23 is provided on the second shell 25.

[0036] In order to facilitate processing and improve the protection level of the waterproof soft light strip, it is preferred that the shell of the electrical connector 4 is fixedly connected to the outer skin of the cable 3 through a beer injection molding process.

[0037] In order to ensure the service life of the waterproof soft light strip, a mesh tail 31 is provided at one end of the outer skin of the cable 3 away from the electrical connector 4, and the mesh tail 31 has a card slot 32. The outer shell 2 is provided with a bayonet that matches the card slot 32, and the sealant in the potting part 22 covers the area where the mesh tail 31 extends into the potting part 22. In this embodiment, a part of the bayonet is located on the first shell 24, and another part of the bayonet is located on the second shell 25. The first shell 24 and the second shell 25 are connected to form a complete bayonet.

[0038] The latch teeth 26 on the first shell 24 hold one side of the flexible protective strip 1, and the latch teeth 26 on the second shell 25 hold the other side opposite to the flexible protective strip 1. Preferably, the latch teeth 26 on the first shell 24 and the latch teeth 26 on the second shell 25 are arranged correspondingly. In this embodiment, the number of the latch teeth 26 on the first shell 24 and the number of the latch teeth 26 on the second shell 25 are both multiple, and the latch teeth 26 on the first shell 24 and the latch teeth 26 on the second shell 25 correspond one to one.

[0039] The number of the potting through holes 11 is one or more, which can be selected and set according to actual needs.

[0040] It should be noted that the potting through hole 11 and the flexible light strip 6 are arranged in a staggered manner, and the potting through hole 11 can be processed and formed on the flexible protection strip 1 after it is formed.

[0041] like Figure 4 As shown, in order to solve the problem of voltage drop of the soft light strip, in some embodiments, the flexible light strip 6 includes a flexible circuit board 61, a lamp bead 62, a positive wiring 63 and a negative wiring 64, the lamp bead 62 is arranged on the front of the flexible circuit board 61, and the positive wiring 63 and the negative wiring 64 are both arranged on the back of the flexible circuit board 61, wherein the current-carrying cross-sectional area of ​​the positive wiring 63 and the negative wiring 64 are both greater than or equal to 2.5mm2, so that when the power per meter of the waterproof soft light strip is less than or equal to 5W, it can ensure that the transmission distance is ≥160 meters when single-ended power supply is used, and there is no difference in brightness at the beginning and the end, thereby achieving the effect of low-voltage (DC48V) long-distance transmission without voltage drop.

[0042] like Figure 4 As shown, in some embodiments, the flexible protective strip 1 includes a connected surface adhesive protective strip 12 and a bottom adhesive protective strip 13, and the flexible light strip 6 is located between the surface adhesive protective strip 12 and the bottom adhesive protective strip 13. In order to improve the impact resistance of the waterproof soft light strip, the outer surface of the surface adhesive protective strip 12 is a curved surface, and the inner side of the surface adhesive protective strip 12 has an escape groove 121 for avoiding the lamp beads 62. In detail, part of the inner side of the surface adhesive protective strip 12 contacts the flexible circuit board 61. Of course, in a specific product, it is also possible that the inner side of the surface adhesive protective strip 12 does not have the escape groove 121. Such a waterproof soft light strip structure can improve the impact resistance level to IK10.

[0043] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
