[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0028] Please refer to Figure 1-Figure 2 The present invention discloses an optical fiber assembly structure, wherein the optical fiber 200 includes a first structural segment and a second structural segment. A PU tube 260 is provided on the periphery of the first structural segment, and a protective tube 280 is provided on the periphery of the second structural segment. The PU tube 260 and the protective tube 280 are sealed by a heat shrink tube.

[0029] A light source assembly is provided at one end of the first structural segment away from the second structural segment. A positioning member 230 is fixed in the light source assembly. The positioning member 230 is used to limit the position of the optical fiber 200 .

[0030] Specifically, in this embodiment, heat shrink tubes are provided on the PU tube 260 and the protective tube 280 , and the heat shrink tubes are heated to shrink and seal the gap between the PU tube 260 and the protective tube 280 , so as to achieve the purpose of sealing.

[0031] At the same time, a positioning member 230 is provided on the light source assembly so that the positioning member 230 limits the end of the light, thereby keeping the distance between the light source on the light source assembly and the end of the light constant at an optimal value to achieve optimal optical performance.

[0032] Furthermore, a sealing assembly is provided at one end of the first structural segment away from the second structural segment, and the sealing assembly includes: a sealing ring 220, which is sleeved on the optical fiber 200; a flange 210, which includes a first connecting part 211 and a second connecting part 212, the first connecting part 211 is perpendicular to the second connecting part 212, the first connecting part 211 is connected to the sealing ring 220, and the second connecting part 212 is embedded in the space between the optical fiber 200 and the PU tube 260.

[0033] Furthermore, a fixing clamp 250 is provided on the outer side of the PU tube 260 for clamping and sealing the PU tube 260 and the second connecting portion 212 .

[0034] A sealing ring 220 and a flange 210 are provided, and the PU tube 260 and the flange 210 are clamped by a fixing clamp 250 to further enhance the sealing performance.

[0035] Furthermore, the first connecting portion 211 and the sealing ring 220 are bonded and fixed.

[0036] Furthermore, the light source assembly includes: an upper cover 100, a lower cover 110 and an LED light-emitting body 120, the upper cover 100 is snap-connected with the lower cover 110, and the relative position of the LED light-emitting body 120 and the lower cover 110 is constant.

[0037] Furthermore, one end of the positioning member 230 is connected to the sealing ring 220 , and the other end is connected to the lower cover 110 .

[0038] Specifically, since the relative position of the LED light-emitting body 120 and the lower cover 110 is constant, the lower cover 110 is against the positioning member 230, and the positioning member 230 limits and fixes the optical fiber 200, so that the distance from the LED light-emitting body 120 to the end of the optical fiber 200 is fixed. By adjusting the position of the LED light-emitting body 120 or adjusting the limiting position of the optical fiber 200, the two can be kept constant at the optimal distance to achieve the best optical performance.

[0039] Furthermore, the lower cover 110 includes a first connecting section 111, a second connecting section 112 and a third connecting section 113, the first connecting section 111 is vertically fixed to one end of the second connecting section 112, and the third connecting section 113 is vertically fixed to the other end of the second connecting section 112; the upper cover 100 is snap-connected with the second connecting section 112.

[0040] Furthermore, the first connecting section 111 abuts against the positioning member 230 , and the second connecting section 112 abuts against the sealing ring 220 .

[0041] The first connecting section 111 and the second connecting section 112 simultaneously press against the positioning member 230 and the sealing ring 220, so that the relative positions between the lower cover 110, the sealing ring 220 and the positioning member 230 remain unchanged, thereby keeping the distance between the LED light source 120 and the optical fiber 200 constant.

[0042] Furthermore, the flange 210 is also fixedly connected with a fixing member 270;

[0043] The lower cover 110 is further provided with a clamping member, which can be folded relative to the lower cover 110 so as to be clamped with the fixing member 270 .

[0044] The fixing member 270 and the clamping member are provided to make the connection between the lower cover 110 and the flange 210 tighter, further improving the sealing performance of the assembly structure.

[0045] Furthermore, the positioning member 230 is provided with at least one protrusion;

[0046] The end of the optical fiber 200 is fixedly connected to a crystal plug 240, and the crystal plug 240 is provided with at least one notch;

[0047] The protrusion abuts against the notch to limit the movement of the optical fiber 200 relative to the positioning member 230 .

[0048] By providing the protrusion and the notch, when the protrusion is sunk into the notch, the crystal head 240 can be limited to achieve the positioning of the end of the optical fiber 200.
