[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example

[0025] See Figures 1 to 3As shown, a plug-in and expandable LED light strip includes a light strip body 1, plug-in terminals 2 are welded and fixed at both ends of the light strip body, and a plurality of extension connection terminals 3 are provided on the edge of the light strip body; in this embodiment, the light strip body and the plug-in terminals are conventional structures of the prior art, which are simply applied and therefore not recorded in detail, and the extension connection terminals are mainly used for plug-in connection, which can realize extension operation and meet the usage requirements of different situations.

[0026] In this embodiment, the top and bottom surfaces of the light strip body are both provided with limit clamps 4. The two limit clamps are connected by a connecting rod 5 that passes through the light strip body, and a spring 6 is provided between the two limit clamps. With this structure, and with the extended connection terminal positioned between the limit clamps, during use, the extended light strip is plugged in and connected to the extended connection terminal, and positioned by the two limit clamps that clamp against the top and bottom surfaces of the extended light strip, respectively. This structure improves the stability of the extended light strip connection, prevents the extended light strip from loosening, falling off, or shaking at the connection, and also prevents the connection from breaking or being damaged, thereby improving stability and reliability.

[0027] In this embodiment, the limiting clamp comprises a C-shaped connecting portion 41 and an arched pressing portion 42 integrally formed therewith. During processing, the C-shaped connecting portion is rotatably connected to the connecting rod via a shaft 43, and the spring is positioned between the two C-shaped connecting portions of the limiting clamp. The edge of the arched pressing portion clamps against the surface of the extended light strip. The spring is primarily used to clamp the two limiting clamps together.

[0028] In this embodiment, the extended connection terminal is located within the arched area of the arched pressing portion, and the length of the arched pressing portion is greater than that of the extended connection terminal. Furthermore, a protective silicone padding layer 7 is adhered to the pressing edge of the arched pressing portion. This not only protects the clamping area, but also prevents damage to the extended light strip.

[0029] In actual use, the limiting clamp is a plastic structure. The light strip body is provided with an on / off control button 8 connected to the expansion connection terminal. The light strip body is also provided with an indicator light 9 connected to the expansion connection terminal. This structure enables control of the expansion connection terminal, while the indicator light facilitates intuitive viewing by the operator.

[0030] The present invention has positive effects: the structure of the present invention is reasonably set up, and an extended connection terminal is provided on the edge of the light strip body, so that it can be plugged and unplugged to connect with the extended light strip. At the same time, a limiting clamp is provided, which can clamp and position the connection of the extended light strip, thereby improving the stability and reliability of the connection, preventing the extended light strip from loosening or falling off, and preventing it from tilting or shaking, thereby improving the stability and reliability of use and having strong applicability.

[0031] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0032] Obviously, the above embodiments of the present invention are merely examples for the purpose of illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
