Description

Technical Field

[0001] The utility model relates to a light belt, in particular to a waterproof structure at the end of the light belt. Background Art

[0002] The ends of the silicone light strips in the prior art are usually encapsulated by adhesive ends or single-layer injection molding, which has poor waterproof effect. In addition, the thickness of the injection-molded part protruding from the outside of the light strip is large, so that after the two light strips are spliced, there will be serious dark areas due to the thickness of the injection-molded part protruding from the outside of the light strip. Utility Model Content

[0003] The utility model provides a waterproof structure for the end of a light strip to solve at least one of the above technical problems.

[0004] To solve the above problems, as one aspect of the utility model, a waterproof structure for the end of a light strip is provided, comprising: a light strip body, a primary injection-molded waterproof part, a secondary injection-molded waterproof part, and a wire connected to the light strip body, a U-shaped circumferential recess is formed circumferentially at the end of the light strip body, an end face of the light strip body is formed with an end face recess connected to the U-shaped circumferential recess, the primary injection-molded waterproof part is arranged in the U-shaped circumferential recess and the end face recess, and the inner wall of the primary injection-molded waterproof part is respectively connected to the outer surface of the U-shaped circumferential recess and the end face recess, the secondary injection-molded waterproof part surrounds the outer surface of the primary injection-molded waterproof part, and a part of the secondary injection-molded waterproof part is located in the U-shaped circumferential recess and the end face recess.

[0005] Preferably, the one-shot injection-molded waterproof portion further comprises a first cylindrical waterproof portion surrounding the outer side of one end of the wire connected to the light strip body.

[0006] Preferably, the secondary injection-molded waterproof portion further includes a second cylindrical waterproof portion surrounding the outside of the first cylindrical waterproof portion.

[0007] Preferably, a clamp is provided on the outer side of the wire, and the second cylindrical waterproof portion extends in a direction away from the light strip body and encapsulates at least a part of the clamp in the second cylindrical waterproof portion.

[0008] Preferably, the primary injection-molded waterproof part and the secondary injection-molded waterproof part are both made of transparent or translucent materials.

[0009] Due to the adoption of the above technical solution, the end of the utility model adopts the double-channel sealing structure formed by the above secondary injection molding, so that the waterproof performance is enhanced. In addition, due to the provision of the U-shaped circumferential recess and the end face recess, a part of the primary injection molded waterproof part and the secondary injection molded waterproof part can be accommodated therein, thereby reducing the thickness of the secondary injection molded waterproof part protruding from the end and both sides of the light strip body, thereby achieving that the secondary injection molded waterproof part between the ends of the two light strip bodies can protrude from the outside of the light strip body with a very thin thickness, which is conducive to the ultra-narrow edge splicing of the light strip, making the spliced ​​dark area smaller, thereby optimizing the splicing dark area problem.

DETAILED DESCRIPTION

[0014] The following is a detailed description of the embodiments of the present invention, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0015] As one aspect of the utility model, a waterproof structure for the end of a light strip is provided, comprising: a light strip body 1, a primary injection-molded waterproof portion 2, a secondary injection-molded waterproof portion 3, and a wire 4 connected to the light strip body 1, a U-shaped circumferential recess 5 is formed circumferentially at the end of the light strip body 1, an end face of the light strip body 1 is formed with an end face recess 6 connected to the U-shaped circumferential recess 5, the primary injection-molded waterproof portion 2 is arranged in the U-shaped circumferential recess 5 and the end face recess 6, and the inner wall of the primary injection-molded waterproof portion 2 is respectively connected to the outer surface of the U-shaped circumferential recess 5 and the end face recess 6, the secondary injection-molded waterproof portion 3 surrounds the outer surface of the primary injection-molded waterproof portion 2, and a part of the secondary injection-molded waterproof portion 3 is located in the U-shaped circumferential recess 5 and the end face recess 6.

If one waterproof seal fails, another waterproof seal can play a certain sealing role.

[0017] Due to the adoption of the above technical solution, the end of the utility model adopts the double-channel sealing structure formed by the above-mentioned secondary injection molding, so that the waterproof performance is enhanced. In addition, due to the provision of the U-shaped circumferential recessed portion 5 and the end face recessed portion 6, a part of the primary injection molded waterproof portion 2 and the secondary injection molded waterproof portion 3 can be accommodated therein, thereby reducing the thickness of the secondary injection molded waterproof portion 3 protruding from the end and both sides of the light strip body 1, thereby achieving that the secondary injection molded waterproof portion 3 between the ends of the two light strip bodies 1 can protrude from the outside of the light strip body 1 with a very thin thickness, which is conducive to the realization of ultra-narrow edge splicing of the light strip, making the spliced ​​dark area smaller, thereby optimizing the splicing dark area problem.

[0018] Preferably, the one-shot injection-molded waterproof portion 2 further includes a first cylindrical waterproof portion 7 surrounding the outer side of one end of the wire 4 connected to the light strip body 1 .

[0019] Preferably, the secondary injection-molded waterproof portion 3 further includes a second cylindrical waterproof portion 8 surrounding the outside of the first cylindrical waterproof portion 7 .

[0020] Preferably, a clamp is provided on the outer side of the wire 4 , and the second cylindrical waterproof portion 8 extends in a direction away from the light strip body 1 and encapsulates at least a part of the clamp in the second cylindrical waterproof portion 8 .

[0021] Preferably, the primary injection-molded waterproof part 2 and the secondary injection-molded waterproof part 3 are both made of transparent or translucent materials, which increases the uniformity of the light-emitting surface.

[0022] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
