[0009] Furthermore, the external wire is connected to the adapter plate laterally or vertically.

[0010] Furthermore, the substrate layer is provided with circuit vias, and the circuit vias are filled with conductors for electrically connecting the circuit layers at different heights.

[0011] Furthermore, the first connection portion is one of a U-shaped hole opening toward the end, a vertically penetrating through hole, an exposed solder joint groove, a soldering convex point, and a plane with an exposed solder joint.

[0012] Furthermore, the second connecting portion is a U-shaped hole opened to the end or a vertically penetrating through hole.

[0013] Furthermore, insulating safety intervals are provided on both sides of each first connecting portion and / or on both sides of each second connecting portion.

[0014] Furthermore, the adapter plate is connected to the end of the light board.

[0015] Furthermore, the second connecting portion of the adapter plate extends out of the light board, and the remaining portion overlaps with the light board.

[0016] Furthermore, each of the first connecting parts has at least one second connecting part electrically connected thereto through the circuit layer.

[0017] The beneficial effects of the present invention are as follows: an adapter plate is provided between the light board and the external wiring, and an overlapping portion is provided between the adapter plate and the light board, thereby increasing the connection area and connection strength with the light board, and enhancing the pulling force between the external wiring and the light board in the horizontal, vertical and various angles, thereby avoiding the problem of falling off and delamination of the LED light strip soldering pads due to repeated high-temperature welding. Furthermore, through the adapter plate, the cable can be extended more conveniently from the side or vertical direction, rather than being limited to the traditional axial outlet, which facilitates adaptation to different scenarios during installation.

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the following is a detailed description of a light strip with a secure cable connection according to the present invention, with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention.

[0031] Please refer to Figures 1-8 , a light strip with firmly connected cables, comprising:

[0032] Light board 100;

[0033] LED lamp beads 200, a plurality of LED lamp beads 200 are arranged at intervals on the lamp board 100;

[0034] The adapter board 300 includes a base layer 310 and at least two circuit layers 320 disposed within the base layer 310. The adapter board 300 is provided with a plurality of first connecting portions 330 and a plurality of second connecting portions 340. The first connecting portions 330 and the second connecting portions 340 are electrically connected via the circuit layer 320. The light board 100 is welded to the first connecting portions 330, and the light board 100 and the base layer 310 have an overlapping portion.

[0035] The external wire 400 is connected to the second connecting portion 340 by welding.

[0036] An adapter plate 300 is provided between the light board 100 and the external wiring 400. There is an overlapping portion between the adapter plate 300 and the light board 100, which strengthens the connection area and connection strength with the light board 100, and enhances the pulling force between the external wiring 400 and the light board 100 in the horizontal, vertical and various angles, thereby avoiding the problem of falling off and delamination of the LED light strip soldering pads due to repeated high-temperature welding. In addition, through the adapter plate 300, the cable can be more conveniently extended from the side or vertical direction, rather than being limited to the traditional axial outlet, which is convenient for adapting to different scenarios during installation. The adapter plate 300 has at least two layers of circuit layers 320, which increases the current flow, and can flexibly adjust the conductive material, thickness, width of each layer of circuit through the design of different numbers of circuit layers to meet the different power requirements of the LED light strip.

[0037] Please refer to Figure 1-Figure 3 , the external wire 400 is connected to the adapter plate 300 laterally or vertically. Lateral and vertical wire outlets can reduce the overall length of the light strip and can adapt to some scenes with shorter installation space. Figure 4 , you can also sample the axial line output as needed.

[0038] Please refer to Figure 5-Figure 8 The substrate layer 310 is provided with a circuit conducting hole 360, which is filled with a conductor 361 for electrically connecting the circuit layers 320 at different heights. The conductor 361 can be filled with a conductive material such as copper paste or silver paste and solidified as needed.

[0039] Please refer to Figure 5-Figure 6 The first connection portion 330 is one of a U-shaped hole opened to the end, a vertical through hole, an exposed solder joint groove, a solder bump, and a plane with exposed solder joints.

[0040] Please refer to Figure 5-Figure 6 The second connecting portion 340 is a U-shaped hole or a vertical through hole that opens to the end. The design method of the open U-shaped hole or through hole can enhance the pulling force during the welding process and improve the stability after welding.

[0041] Please refer to Figure 5-Figure 8 Insulating safety gaps 350 are provided on both sides of each first connecting portion 330 and / or on both sides of each second connecting portion 340. The provision of insulating safety gaps 350 improves safety and prevents short circuits caused by excessively large solder joints during welding. Preferably, the insulating safety gaps 350 are formed directly from the outer substrate layer 310, and can be formed by injection molding, cutting, molding, or other methods. In particular, the insulating safety gaps 350 are ribs.

[0042] Please refer to Figures 1-4 , the adapter plate 300 is connected to the end of the light board 100. The wires can also be routed out from the middle of the light board 100 as needed.

[0043] Please refer to Figures 1-4 The second connecting portion 340 of the adapter plate 300 extends out of the light board 100, and the remaining portion overlaps with the light board 100. The area of ​​the overlapping portion is increased, thereby improving stability. Preferably, the impulse portion of the adapter plate 300 and the light board 100 can be strengthened and fixed by welding, gluing, or riveting.

[0044] Preferably, each first connection portion 330 has at least one second connection portion 340 electrically connected thereto through the circuit layer 320. That is, each first connection portion 330 has at least one corresponding second connection portion 340. Preferably, the first connection portions 330 and the second connection portions 340 correspond one to one.

[0045] It is understood that the adapter plate 300 can be designed with regular or irregular shapes depending on the requirements of the LED light strip. The base material layer 310 can be made of either rigid or flexible materials, such as FPC, FR4, or aluminum, allowing for flexible adjustment of the material of the welding adapter plate 300 as needed. Similarly, the light board 100 can also be made of rigid or flexible materials, such as commonly used FPC or aluminum, to meet different needs.

[0046] Understandable, please refer to Figure 7 , the substrate layer 310 can be a single layer wrapped circuit layer 320, or, please refer to Figure 8 Alternatively, a multi-layer laminated circuit layer 320 may be used, depending on the material used and the needs.

[0047] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0048] In addition, if the embodiments of the present invention include descriptions of "first," "second," etc., such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0049] In summary, the utility model provides a light strip with a firmly connected cable, which strengthens the connection area and connection strength with the light board, enhances the pulling force between the external wire and the light board in the horizontal, vertical and various angles, and avoids the problem of falling off and delamination of the LED light strip soldering pads due to repeated high-temperature welding. And through the adapter plate, the cable can be more conveniently extended from the side or vertical direction, instead of being limited to the traditional axial outlet, which is convenient for installation to adapt to different scenarios. Moreover, it is flexible and changeable, and can meet different situations and adapt to various construction environment requirements by designing different numbers of circuit layers, designing different materials, thicknesses, widths of circuit layers, and designing the shape and material of the substrate layer.
