[0002] LED linear lights, as an important linear lighting device, are widely used in various scenarios such as commercial lighting, home decoration, building outlines, indoor and outdoor advertising light boxes, and display case lighting due to their advantages such as uniform and soft light, simple and beautiful appearance, and flexible installation methods.
[0003] In practical applications of LED linear lights, reliable electrical connection ports are required for multi-lamp series connection, power access, and signal transmission. For a long time, the industry has commonly used externally mounted or specifically installed injection-molded junction boxes for wiring connections. However, these junction boxes themselves have a certain thickness, significantly increasing the overall height of the light fixture, making them unsuitable for installation in shallow light troughs and other thin spaces, thus limiting their application range. Furthermore, injection-molded junction boxes are usually introduced as independent outsourced components, directly increasing production costs; more importantly, these standardized outsourced components cannot flexibly change to adapt to the specific type of LED linear light, exhibiting a significant lack of compatibility.
[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0014] Furthermore, the male and female cables are respectively provided with plugs, the plugs are slidably connected to the cable groove, and the cable groove is provided with a spring piece for locking the position of the plug.
[0015] Furthermore, the plug has a through hole for the male and female cables to pass through, and a through groove at the bottom that communicates with the through hole. The through groove extends to both ends of the plug. The male and female cables are provided with an anti-detachment block at the end of the plug near the PCB adapter board. The anti-detachment block abuts against the end of the plug near the PCB adapter board.
[0016] Furthermore, the cross-sections on both sides of the groove are in the shape of a "7", and the two ends of the plug are provided with limiting parts that are slidably connected to the groove and have a "convex" shape. The limiting parts are slidably connected to the groove.

Detailed Implementation
[0029] This utility model provides a lamp body wiring structure for an LED linear light and the LED linear light itself. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0030] In the description of this utility model, it should be understood that the terms "upper," "lower," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.
[0031] Please see Figures 1 to 5 As shown, this utility model provides a lamp body wiring structure for an LED linear light, including: a lamp body 1, a lamp board 2, a PCB adapter board 3, a male cable 5, a female cable 6, and a potting layer 7; the lamp board 2 is disposed inside the lamp body 1, extending along the length direction of the lamp body 1, and multiple LED beads are welded on the lamp board 2 at intervals; a wire groove 11 extending along the length direction is provided on the back of the lamp body 1 near the lamp board 2; the PCB adapter board 3 is disposed on the wire groove 11, and the PCB adapter board 3 is electrically connected to the lamp board 2 through a plug-in terminal assembly 4; both the male cable 5 and the female cable 6 are electrically connected to the PCB adapter board 3; the potting layer 7 fills the wire groove 11 and completely covers and encapsulates the PCB adapter board 3.
[0032] During assembly, after the lamp board 2 is installed into the lamp body 1, the PCB adapter board 3 is installed in the predetermined position of the cable tray 11, and the lamp board 2 and the PCB adapter board 3 are electrically connected through the plug-in terminal assembly 4. Then, the male cable 5 and the female cable 6 are installed in the cable tray 11 and soldered to the PCB adapter board 3 respectively. Finally, potting material is filled into the cable tray 11 to form a potting layer 7. After curing, the potting layer 7 covers the entire PCB adapter board 3 and the solder joints, providing waterproof and insulating protection. The incoming cable structure PCB adapter board 3 and the cables are directly integrated into the space of the cable tray 11 that is usually present on the back of the lamp body 1.
[0033] Compared to existing technologies, since the lamp body's wiring structure is completely built into the original wire groove 11 of the lamp body 1, and the height of the potting layer 7 does not exceed the depth of the wire groove 11, the overall lamp height can be effectively reduced by 3-5mm, allowing LED linear lights to be installed in thin spaces such as shallow light grooves. Secondly, it eliminates the cost of externally purchased independent injection-molded junction box components, significantly reducing the overall production cost. In addition, the PCB adapter board 3, male cable 5, and female cable 6 can be adaptively replaced according to the type of LED linear light, greatly improving the adaptability and application flexibility of the entire wiring structure to different types of LED linear lights, and improving the production line's production efficiency.
[0034] The potting material mentioned above can be epoxy resin, PU adhesive, or silicone. In actual assembly, after the PCB adapter board 3 and cables are installed, testing can be conducted. If the test fails, the corresponding component can be replaced. Potting and encapsulation will only be performed after the test passes.
[0035] In a preferred embodiment, see [reference] Figure 2 , 3 The connector assembly 4 includes a female connector 41 soldered onto the lamp board 2 and a male connector 42 soldered onto the PCB adapter board 3. The female connector 41 and the male connector 42 are connected to each other to achieve a telecommunication connection between the PCB adapter board 3 and the lamp board 2. Specifically, both the female connector 41 and the male connector 42 adopt a multi-pin structure design, which allows the transmission of multiple signals and enables precise control over the operating status of the LED beads on the lamp board 2, such as brightness, color, and dynamic effects, giving the LED strip lights a rich variety of lighting effects.
[0036] In the alternative solution, the female connector 41 can be soldered onto the PCB adapter board 3, and the male connector 42 can be soldered onto the lamp board 2.
[0037] In a preferred embodiment, see [reference] Figure 2 The male cable 5 and female cable 6 are located at opposite ends of the PCB adapter board 3, and the potting layer 7 is located in the area between the male cable 5 and female cable 6. The male cable 5, female cable 6, and the sidewall of the cable tray 11 form a relatively enclosed potting space. The potting layer 7 fills and cures within this specific area, achieving sealing and protection of the PCB adapter board 3 and its connections within this space.
[0038] In a preferred embodiment, see [reference] Figure 2 The male cable 5 and the female cable 6 are each provided with a plug 8, which is slidably connected to the cable groove 11. The cable groove 11 is provided with a spring piece 9 for locking the position of the plug 8. The plug 8 forms an effective seal with the inner wall of the cable groove 11, thereby precisely limiting the flow range of the potting material during the potting process and preventing it from leaking into non-target areas within the cable groove 11.
[0039] Further, see Figure 2 , 5 The plug 8 has a through hole 81 for the male cable 5 and female cable 6 to pass through, and a through groove 82 at the bottom communicating with the through hole 81. The through groove 82 extends to both ends of the plug 8. An anti-detachment block 10 is provided at the end of the male cable 5 and female cable 6 near the PCB adapter board 3, and the anti-detachment block 10 abuts against the end of the plug 8 near the PCB adapter board 3. During installation, the operator can flip the plug 8 outward along its through groove 82 to easily insert the cable into the through hole 81. Then, the plug 8 is restored to its closed state, enabling rapid assembly of the plug 8 and the cable, significantly improving installation efficiency. Furthermore, the anti-detachment block 10 effectively restrains the cable when there is an outward pulling force along the cable axis, preventing axial displacement of the cable relative to the plug 8 and the lamp body 1, thereby avoiding failure of the solder joint between the cable and the PCB adapter board 3 due to displacement tension.
[0040] In a preferred embodiment, see [reference] Figure 3 , 5 The cross-sections on both sides of the cable trough 11 are in the shape of a "7". The two ends of the plug 8 are provided with limiting parts 83, which are convex in shape and slidably connected to the cable trough 11. These limiting parts 83 are slidably connected to the cable trough 11. Through this design, the plug 8 can only slide along the length of the lamp body 1, while its convex upper edge effectively engages with the horizontal wall of the cable trough 11, ensuring that the plug 8 will not radially detach during operation or vibration. Furthermore, the operator can flexibly adjust the horizontal installation position of the plug 8 and the cable fixed to it on the lamp body 1 along the axial direction according to actual needs. Combined with the locking effect of the spring piece 9 on the cable trough 11, the plug 8 and the cable can be reliably locked at any adjusted position, jointly ensuring the stability of the entire inlet structure after installation.
[0041] Further, see Figure 4 , 5 The spring piece 9 has U-shaped claws 91 on both sides. The spring piece 9 is adapted to the top of the plug 8, and the claws 91 are engaged with the inner wall of the groove 11. Specifically, the plug 8 has a recess 84 in the middle that matches the shape of the spring piece 9. During assembly, the spring piece 9 needs to be precisely aligned with the recess 84 and vertical pressure applied. The pressing action causes the U-shaped claws 91 on both sides of the spring piece 9 to contract and deform, allowing it to smoothly enter the groove 11. Subsequently, the claws 91 recover part of their deformation in the groove and expand outward, so that the outer edges of the U-shaped openings elastically press against the two opposite inner walls of the groove 11, finally fixing the spring piece 9 in the recess 84, thus reliably locking the position of the plug 8.
[0042] In a preferred embodiment, see [reference] Figure 2 The bottom of the wire trough 11 has a window 12 corresponding to the position of the female connector 41. The PCB adapter board 3 covers the window 12 and is installed in the wire trough 11 by screws 31. With the above configuration, after the lamp board 2 is installed into the lamp body 1, the lamp board 2 and the female connector 41 can be easily soldered and fixed through this window 12. Secondly, the installation of the PCB adapter board 3 is significantly improved by using the screw 31 installation method. Finally, the PCB adapter board 3 tightly covers the entire opening of the window 12, forming an effective barrier to prevent the potting material from leaking from the window 12 area into the lamp body 1, ensuring the reliability of the seal.
[0043] In a preferred embodiment, see [reference] Figure 2 The side wall of the cable tray 11 has a notch 13, through which the male cable 5 and / or female cable 6 can be led out to the outside of the lamp body 1. By providing the notch 13, the male cable 5 and / or female cable 6 are allowed to pass through it and be led out to the outside of the lamp body 1, thereby flexibly adapting to various wiring paths required for the installation of LED linear lights.
[0044] In summary, this utility model highly integrates the PCB adapter board 3, male cable 5, and female cable 6 within the inherent cable groove 11 on the back of the lamp body 1. The PCB adapter board 3 achieves electrical connection with the lamp board 2 through the plug-in cooperation of the multi-core structured female connector 41 and male connector 42. The male cable 5 and female cable 6 are secured in the cable groove 11 by sliding plugs 8 and locking springs 9, and are soldered to the PCB adapter board 3 for conduction. The plugs 8 cooperate with the side wall of the cable groove 11 to define a specific potting area. After the potting material fills this area and cures, it forms a potting layer 7 covering and protecting the PCB adapter board 3 and the cables. Compared with the prior art, it can make full use of the depth space of the cable groove 11, significantly reducing the overall lamp height by 3-5mm, making it perfectly adaptable to thin installation environments such as shallow light grooves; it completely eliminates the need for externally purchased injection-molded junction boxes, greatly simplifying the structure and reducing production costs; at the same time, the replaceable design of the PCB adapter board 3 and cables significantly improves the overall structure's adaptability and application flexibility for different types of LED linear lights.
[0045] This utility model also discloses an LED linear light, including the lamp body wiring structure of the LED linear light. By integrating the lamp body wiring structure into the lamp body 1, the overall height of the LED linear light is significantly reduced, making it perfectly adaptable to the installation requirements of thin spaces such as shallow light troughs; at the same time, the replaceable design of the lamp body wiring structure effectively improves the adaptability and application flexibility of the overall lighting fixture to different application needs and types.
