Description

Technical Field

[0001] This utility model relates to the field of LED light strip technology, specifically to a tensile-resistant flexible light strip. Background Technology

[0002] LED light strips are products made by mounting LED light-emitting diodes (LEDs) onto a strip of flexible printed circuit board (FPC) or rigid PCB. These strip-shaped products have a long lifespan, are energy-efficient and environmentally friendly, and are widely used in various decorative industries. LED light strips can be cut to the appropriate length as needed, and their flexibility allows for bending and hanging, making installation and application more flexible. Existing LED light strips typically use soldering to connect leads to the power adapter, resulting in poor solder joint strength. Some flexible LED light strip products use a piercing connection method, using metal fragments to pierce the light strip and connect it to the printed circuit. All of these existing technologies suffer from low tensile strength. Flexible LED light strips are usually quite long and are often installed by hanging. Even if adhesive is used for fixation, the adhesive is prone to aging and failure. The weight of the light strip creates a load at the connection points, leading to poor contact and other malfunctions, seriously affecting the product's application. Therefore, existing technologies require improvement and development. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a reasonably structured, tensile-resistant, and flexible light strip.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The present invention discloses a tensile-resistant flexible light strip, comprising a base strip and a wire fastener. An LED light-emitting chip is mounted on the base strip. The wire fastener has a wiring groove that extends through its first end to form a wire inlet, through which the base strip is inserted. The wire fastener contains a wire clamping structure that holds the base strip, thereby enabling the wire fastener to connect.

[0017] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1-3 As shown, the present invention provides a tensile-resistant flexible light strip, comprising a base strip 1 and a wire fastener 2. The base strip 1 is a flexible circuit board, on which LED light-emitting chips 11 are mounted. The wire fastener 2 is provided with a wiring groove 21, which extends through the first end of the wire fastener 2 to form a wire inlet 22. The base strip 1 is inserted into the wiring groove 21 through the wire inlet 22. The wire fastener 2 is provided with a wire clamping structure, which clamps the base strip 1 to connect it to the wire fastener 2. The wire fastener 2 is provided with a power connection component for connecting the base strip 1.

[0019] It is understood that the baseband 1 is a flexible FPC circuit board, and a number of LED light-emitting chips 11 are packaged and disposed on the baseband 1 through a mounting process. The LED light-emitting chips 11 are electrically connected to the printed circuit in the baseband 1.

[0020] Specifically, the cable holder 2 has a cable routing groove 21 and an inlet 22 communicating with the cable routing groove 21. The baseband 1 can be inserted into the cable routing groove 21 through the inlet 22. The clamping structure holds the baseband 1 to fix it to the cable holder 2, and the baseband 1 cooperates with the power connection component to form an electrical connection.

[0021] The wire fastener 2 of this invention clamps and connects the baseband 1 through a wire-clamping structure, ensuring a stable and reliable electrical connection between the power connection component and the baseband 1, and avoiding problems such as poor contact caused by pulling. Furthermore, the wire fastener 2's fixed connection to the baseband 1 allows the baseband 1 to be suspended and used normally under heavy loads. Consequently, the baseband 1 can be used as a conductive line, satisfying lighting installation requirements, and can also serve as a power supply line for other electrical devices, improving application flexibility.

[0022] The power connection assembly includes a universal interface 12 and two piercing pieces 13. The second end of the cable holder 2 has an installation port 23, which connects to the wiring groove 21. The universal interface 12 is fixedly installed within the installation port 23, and two piercing pieces 13 are connected to the universal interface 12. These two piercing pieces 13 extend into the wiring groove 21 to connect with the baseband 1. As described above, the baseband 1 is a flexible FPC circuit board. The piercing pieces 13 can be electrically connected to the printed circuit by piercing the baseband 1. The two piercing pieces 13 respectively form the live wire and neutral wire, connecting the universal interface 12 and the baseband 1. Furthermore, the through-hole interface 12 facilitates quick installation and circuit connection of the light strip. The universal interface 12 can use existing quick-connect interfaces; the specific structure is not described here. However, using the universal interface 12 expands the application range of the light strip and makes it more convenient for use in decoration and renovation.

[0023] Specifically, the cable holder 2 includes a base 3 and a top cover 4. A rotating shaft 31 is provided at the first end of the base 3. Side cover plates 41 are provided on both sides of the top cover 4. Pin holes 42 are provided at the first end of each side cover plate 41, and these pin holes 42 are paired with the rotating shaft 31, allowing the top cover 4 to be rotatably mounted on the base 3. When the top cover 4 is closed on the base 3, a cable routing groove 21 is formed between them, and a cable clamping structure is located between the base 3 and the top cover 4. Preferably, the top cover 4 and the base 3 are rotatably connected via the rotating shaft 31. Opening and closing the top cover 4 makes it easier for the baseband 1 to be inserted into the cable routing groove 21 and paired with the split piece 13. In particular, the top cover 4 has a flat interface, and the top cover 4 is connected to the rotating shaft 31 via two side cover plates 41. When the top cover 4 is opened, the first end of the top cover 4 rotates relative to the base 3, thus retaining the cable inlet 22.

[0024] Furthermore, the base 3 has a winding post 35 at its first end, and the upper cover 4 has a clearance wedge surface 46 on its mating surface that mates with the winding post 35, forming a wire inlet 22 between the clearance wedge surface 46 and the winding post 35. As described above, during the opening and closing process of the upper cover 4, the clearance wedge surface 46 rotates relative to the winding post 35, such as... Figure 2 As shown, the winding post 35 is arranged horizontally so that its outer edge is opposite to the avoidance wedge surface 46, so that the upper cover 4 can always leave the inlet 22 when rotating on the base 3, so that the baseband 1 can be inserted into the wiring groove 21.

[0025] The base 3 has a locking hole 32 at its second end, and the side cover 41 has a rivet eye 43 at its second end. When the upper cover 4 is closed on the base 3, the rivet eye 43 and the locking hole 32 are paired. The upper cover 4 and the base 3 can be fixedly connected by inserting rivets into the locking hole 32 and the rivet eye 43. After the baseband 1 is inserted into the cable tray 21, the upper cover 4 and the base 3 are closed so that the rivet eye 43 and the locking hole 32 are aligned. The rivets can be existing conventional connectors such as self-tapping screws. After locking the upper cover 4 and the base 3, the baseband 1 can be clamped and fixed in the cable holder 2. Using rivets to fix it can increase the connection strength of the cable holder 2, so that the cable clamping structure can better clamp and fix the baseband 1.

[0026] The clamping structure includes a first roller block 33 and a second roller block 44. The first roller block 33 is disposed on the mating surface of the base 3, and the second roller block 44 is disposed on the mating surface of the upper cover 4. When the upper cover 4 is closed on the base 3, the first roller block 33 and the second roller block 44 are mated to clamp the baseband 1 that passes through the wiring groove 21. Specifically, multiple curved contours are distributed on the mating surfaces of the first roller block 33 and the second roller block 44. The mating of multiple undulating curved contours can better clamp the baseband 1 and avoid the slippage that exists in planar clamping.

[0027] The second end of the base 3 is provided with an end seat 34, and the mounting port 23 is opened on the end seat 34. The breaking piece 13 is fixedly set on the mating surface of the base 3. The wire clamping structure also includes a wire pressing block 45, which is set on the mating surface of the upper cover 4, so as to be mated with the breaking piece 13.

[0028] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
