[0027] In order to make the objectives, technical solutions and advantages of this application clearer, this application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] As shown in Figures 1 to 3, the present application discloses a light strip connector 100 for connecting two adjacent light strips 200. The light strip 200 includes a light strip body 201 and a solder pad 202 fixed inside the light strip body 201. An accommodating space 203 is defined inside the light strip body 201, and the solder pad 202 is fixed inside the accommodating space 203. When the light strip connector 100 is inserted into the accommodating space 203, an electrical connection is achieved between the light strip connector 100 and the light strip 200.

[0029] As shown in Figures 4 to 8 in conjunction with Figure 2, the light strip connector 100 includes a cover 10, a base 20, and an electrical connection structure 30. The cover 10 is connected to the base 20 and defines a receiving space 21 therein. The cover 10 and the base 20 can be movably opened to allow the light strip 200 to enter from both sides of the base 20, and the cover 10 and the base 20 can mutually clamp the light strip 200. Specifically, the electrical connection structure 30 is accommodated within the receiving space 21. The ends of the receiving space 21 are open to facilitate securing the electrical connection structure 30 and the light strip body 201 within the receiving space 21. The electrical connection structure 30 includes a body 31 and conductive terminals 32 fixedly connected to the body 31. The conductive terminals 32 are configured to electrically connect to the solder pads 202. Preferably, the conductive terminals 32 are fixed to the body 31 and exposed on both sides of the body 31 to electrically connect to the light strip 200 entering from both sides of the base 20.

[0030] A rotating structure is formed between the cover 10 and the base 20, and its rotation range is 0 to 180 degrees. The cover 10 and the base 20 can open or close the receiving space 21 through the rotating structure, thereby facilitating the insertion of the light strip 200 and the light strip connector 100 and facilitating operation. In a preferred embodiment, the rotating structure is a thin plate, preferably a plastic plate. In other embodiments, the rotating structure can be a rotating shaft or other components capable of realizing a rotation function, which can be set according to actual use requirements and is not limited to this.

[0031] In this embodiment, the cover 10 and the base 20 are both made of plastic to enhance the plasticity of the product; the cover 10, thin plate and base 20 are integrally injection molded, which is beneficial for manufacturers to carry out mass production with high production efficiency, and is also convenient for users to use.

[0032] The base 20 includes a bottom wall 23 and side walls 24 disposed on either side of the bottom wall 23. The bottom wall 23 and the side walls 24 enclose the receiving space 21 for accommodating the light strip 200. A first snap-fit ​​portion 241 is disposed on the outer surface of the side wall 24. The cover 10 is configured to cooperate with the base 20 to secure the light strip 200 within the receiving space 21. The cover 10 is configured to have a second snap-fit ​​portion 11 that cooperates with the first snap-fit ​​portion 241. The snap-fitting interaction between the first snap-fit ​​portion 241 and the second snap-fit ​​portion 11 allows the cover 10 to be secured to the base 20.

[0033] In this embodiment, the first snap-fitting portion 241 is a protrusion, and the second snap-fitting portion 11 is a groove that cooperates with the protrusion. Of course, in other embodiments, the first snap-fitting portion 241 may also be a groove, and the second snap-fitting portion 11 may be a protrusion that cooperates with the groove; or the first snap-fitting portion 241 and the second snap-fitting portion 11 may also be other mutually cooperating structures, which are not limited here.

[0034] The inner wall surface of the cover portion 10 is provided with a plurality of first abutting portions 12 for abutting and pressing the light strip 200, so that the light strip 200 is firmly fixed in the receiving space 21. Preferably, two groups of the first abutting portions 12 are provided, and are respectively provided at both ends of the cover portion 10, so that two adjacent light strips 200 can be fixed. The inner wall surface of the cover portion 10 is also provided with a second abutting portion 13 located between the two groups of first abutting portions 12. The second abutting portion 13 is used to abut and press the electrical connection structure 30, so that the electrical connection structure 30 is firmly fixed in the receiving space 21.

[0035] Furthermore, a plurality of ribs 242 are provided on the outer wall surface of the side wall 24 to prevent the user from disassembling it with bare hands, thereby avoiding the risk of electric shock to the user.

[0036] Taking into account that the covering part 10 is prone to deformation after long-term heat or pressure deformation, resulting in loss of pressure, thereby causing the connection between the electrical connection structure 30 and the light strip 200 to fail, the present application has made improvements to the base 20 and the electrical connection structure 30, so that the electrical connection structure 30 and the base 20 are tightly matched with each other, realizing the electrical connection between the electrical connection structure 30 and the light strip 200. Even if the covering part 10 loses pressure, it will not affect the electrical connection between the electrical connection structure 30 and the light strip 200, thereby greatly improving the reliability of the electrical connection.

[0037] Specifically, as shown in Figures 5 to 8, a positioning groove 221 and a card slot 222 located next to the positioning groove 221 are provided on the side wall 24 of the base 20, and a positioning block 310 and a card block 311 located next to the positioning block 310 are correspondingly provided on the main body 31. When the electrical connection structure 30 is installed in the base 20, the positioning block 310 is limited and accommodated in the positioning groove 221, and the card block 311 is snapped into the card slot 222. In this way, the electrical connection structure 30 is limited in the receiving space 21.

[0038] Specifically, the positioning groove 221 is formed in a recessed manner on the side wall 24 of the base 20, and the card slot 222 is also formed in a recessed manner on the side wall 24 of the base 20, and the extension direction of the card slot 222 is perpendicular to the extension direction of the positioning groove 221, so that the body 31 can be limited in different directions. The positioning block 310 continues to extend outward from the outer wall of the body 31, and the positioning block 310 extends beyond the card block 311. A card arm 314 is connected to the outer wall of the body 31, and the card block 311 is arranged at the end of the card arm 314. A guide surface 223 is provided on the side of the positioning groove 221 close to the covering portion 10, for guiding the positioning block 310 into the positioning groove 221.

[0039] Preferably, two clamping slots 222 are provided and are disposed on both sides of the positioning slot 221, and two clamping arms 314 are correspondingly provided and are disposed on both sides of the positioning block 310. Furthermore, the clamping slots 222 and the positioning slots 221 are provided on opposite side walls of the base 20, and the clamping blocks 311 and the positioning blocks 310 are correspondingly provided on opposite sides of the body 31, thereby ensuring that the electrical connection structure 30 is stably fixed in position within the base 20, achieving a tight fit between the electrical connection structure 30 and the base 20, and ensuring that the electrical connection structure 30 can maintain electrical connection with the light strip 200.

[0040] The main body 31 includes a first main body portion 312 and a second main body portion 313 that are perpendicular to each other, and the second main body portion 313 is arranged perpendicular to the side wall 24 of the base 20. The conductive terminals 32 are fixed on the first main body portion 312 and exposed at both ends of the first main body portion 312, so as to facilitate electrical connection with the solder pads 202 inside the light strip main body 201. Preferably, the first main body portion 312 is provided in two rows and is spaced apart from each other. The clamping block 311 and the positioning block 310 are both provided on the second main body portion 313, and the second main body portion 313 and the first main body portion 312 are arranged in a cross shape, so that the conductive terminals 32 are exposed on both sides of the second main body portion 313 to electrically connect two adjacent light strips 200.

[0041] Preferably, the conductive terminals 32 are arranged in sheet form on the lower surface of the first body portion 312 and on both sides of the second body portion 313 , so that the conductive terminals 32 can be inserted into the light strip body 201 and electrically contact the pads 202 .

[0042] In addition, in the present application, at least two first snap-fit ​​portions 241 are provided, which are respectively located on the outside of the positioning groove 221 and the snap-fit ​​groove 222, so that when the cover portion 10 and the base 20 are snap-fitted to each other, the second body portion 313 can also be clamped in the width direction of the light strip connector 100, that is, in the extension direction of the second body portion 313, so that the electrical connection structure 30 is more stably fixed in the base 20. In this embodiment, three first snap-fit ​​portions 241 are provided, corresponding to the positioning groove 221 and the snap-fit ​​grooves 222 located on both sides of the positioning groove 221. Of course, in other embodiments, the first snap-fit ​​portion 241 may not be provided on the outside of the snap-fit ​​groove 222, as long as the clamping of the second body portion 313 can be achieved, and this is not limited here.

[0043] As shown in Figure 9 in combination with Figures 1 and 2, during assembly, the electrical connection structure 30 is first inserted into the light strips 200 on both sides respectively, and the conductive terminals 32 are electrically connected to the solder pads 202 in the accommodating space 203; then, the electrical connection structure 30 and the light strip 200 are installed as a whole into the base 20, and the mutual cooperation between the positioning block 310 and the positioning groove 221 and the mutual cooperation between the clamping block 311 and the clamping groove 222 are used to make the electrical connection structure 30 and the base 20 fit tightly together; finally, the covering part 10 is folded over until it is buckled and fixed with the base 20, and the light strip 200 is clamped and fixed again, and the installation is completed at this time.

[0044] In summary, the light strip connector 100 of the present application defines positioning grooves 221 and latching grooves 222 on opposite side walls 24 of the base 20, and corresponding positioning blocks 310 and latching blocks 311 are provided on the body 31 of the electrical connection structure 30. Thus, the electrical connection structure 30 can be fixed within the base 20 by utilizing the mutual cooperation between the positioning blocks 310 and the positioning grooves 221, and the mutual cooperation between the latching blocks 311 and the latching grooves 222. This allows the electrical connection structure 30 to be tightly fitted with the base 20, thereby achieving electrical connection between the electrical connection structure 30 and the light strip 200. Compared to the prior art, the light strip connector 100 of the present application does not affect the electrical connection between the electrical connection structure 30 and the light strip 200 even if the cover 10 loses pressure. That is, the electrical pressure does not rely on the snap-fitting of the cover 10, greatly improving the reliability of the electrical connection.

[0045] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
