Description
Technical Field
[0001] This utility model relates to the field of LED lighting technology, and in particular to a novel connector for LED light strips. Background Technology
[0002] LED light strips are made by assembling LEDs onto a strip-shaped FPC (flexible printed circuit board) or PCB (rigid PCB), and are named for their strip-like shape. Because of their long lifespan, energy efficiency, and environmental friendliness, they are widely used in decorative lighting industries such as automobiles, decoration, signage, advertising signs, wine cabinets, jewelry cabinets, entertainment venues, pathways, and outline markings.
[0003] To facilitate production, processing, and market distribution, LED light strips are only available in a few fixed lengths. However, in actual use, the required length varies greatly depending on the user or location. This necessitates that LED light strips be cut or spliced to meet the specific length requirements. Connectors are needed when splicing LED light strips to ensure electrical connection between the two sections.
[0004] Currently, there are two main connection methods for LED light strips on the market. One is a male-female connector, but it is bulky and cannot support multi-line connections; the other uses three connectors, but its contact is unreliable and its performance is poor. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a novel connector for LED light strips.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A novel LED light strip connector, comprising a male end assembly and a female end assembly. The female end assembly includes a female end fixing plate and a block-shaped female end body disposed on the female end fixing plate. Several mounting grooves are spaced apart on both sides of the female end body. A female end terminal is disposed within each mounting groove. Each female end terminal includes two spaced-apart spring connecting pieces. Connecting protrusions are provided on opposite sides of the two spring connecting pieces. Two snap-fit grooves are symmetrically disposed at both ends of the female end body. The male end assembly includes a male end body. The male end body is an overall groove-shaped block with an opening downwards and through-holes at both ends. A mounting block is disposed within the groove of the male end body. Several male end terminals are spaced apart within the mounting block. The side of the male end terminal adjacent to the female end assembly is plate-shaped. A snap-fit block is disposed at each end of the side of the male end body adjacent to the female end assembly. The snap-fit blocks engage with the corresponding snap-fit grooves.
[0007] By adopting the above technical solution, a female end body, a female end terminal, a snap-fit groove, a male end body, a male end terminal, and a snap-fit block are set. The female end terminal adopts a design with two spring connecting pieces and connecting protrusions, which form a knife-type contact with the sheet-like male end terminal, ensuring stable contact. Mounting grooves are set on both sides of the female end body and female end terminals are installed, so that male end components can be connected to both sides of the female end body, realizing two-in-one and three-in-one connections. The male end component and the female end component are snapped together by snap-fit blocks and snap-fit grooves, making assembly convenient.
[0008] Furthermore, the snap-fit groove includes a first limiting groove and a second limiting groove. The first limiting groove is opened inward from the end face of the female end body and is located in the lower part of the inner side of the end face. The second limiting groove is opened inward from the end face of the female end body and is located in the upper part of the outer side of the end face. The depth of the second limiting groove is greater than the depth of the first limiting groove. An insertion interface is provided on the side of the upper groove of the first limiting groove near the male end component. A first limiting block is horizontally arranged in the second limiting groove. The first limiting block is a trapezoidal block whose ground surface coincides with the bottom surface of the second limiting groove. The snap-fit block includes an L-shaped protrusion and a second limiting block. The L-shaped protrusion is arranged on the side of the male end body groove wall near the female end body. A side plate is provided on the outer side of the L-shaped protrusion. The second limiting block is arranged on the side of the male end body groove wall near the L-shaped protrusion. The second limiting block is a pentagonal block with a smaller cross-sectional area on the side near the female end component than on the side away from the female end component.
[0009] By adopting the above technical solution, a first limiting groove, a second limiting groove, a first limiting block, an L-shaped protrusion, and a second limiting block are set. The L-shaped protrusion is inserted obliquely into the first limiting groove from the insertion interface to achieve left and right limiting between the male end body and the female end body. The first limiting block and the second limiting block achieve up and down limiting between the male end body and the female end body.
[0010] Furthermore, each end of the male end body away from the female end assembly is provided with a T-shaped groove, a T-shaped block is provided in the T-shaped groove, and a connecting plate is provided on the bottom end of the T-shaped block protruding outward. The connecting plate is used to connect with the LED light strip plate.
[0011] By adopting the above technical solution, T-shaped grooves and T-shaped blocks are set, and then the connecting plate on the T-shaped block is connected to the LED light strip board, thereby realizing the connection between the male end body and the LED light strip.
[0012] Furthermore, a support strip is provided at the bottom of the male end body on the side of the T-shaped groove near the female end assembly.
[0013] By adopting the above technical solution and setting a support strip, when the male end body is attached to the LED light strip plate, the support strip contacts the LED light strip plate, which prevents the male end body from falling off the LED light strip plate due to the center of gravity.
[0014] Furthermore, the female end body has insertion slots at both ends from the bottom inward, and two insertion blocks are correspondingly provided on the female end fixing plate.
[0015] By adopting the above technical solution, a plug-in slot and a plug-in block are set to realize the connection between the female end fixing plate and the female end body.
[0016] In summary, this utility model has the following beneficial effects: In this application, a female end body, a female end terminal, a snap-fit groove, a male end body, a male end terminal, and a snap-fit block are provided. The female end terminal adopts a design with two spring connecting pieces and connecting protrusions, forming a knife-type contact with the sheet-like male end terminal, ensuring stable contact. Mounting grooves are provided on both sides of the female end body, and female end terminals are installed thereon, so that male end components can be connected to both sides of the female end body, enabling two-in-one and three-in-one connections. The male end component and the female end component are snap-fitted together by the snap-fit block and the snap-fit groove, making assembly convenient. Attached Figure Description

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0027] like Figure 1-8 As shown in the embodiment of this application, a novel LED light strip connector is disclosed, including a male terminal assembly and a female terminal assembly. The female terminal assembly includes a female terminal fixing plate 10 and a block-shaped female terminal body 20 disposed on the female terminal fixing plate 10. A plurality of mounting grooves 21 are spaced apart on both sides of the female terminal body 20, and female terminal 22 is disposed in the mounting grooves 21. Both sides of the female terminal body 20 can be connected to the male terminal assembly to realize a two-in-one or three-in-one connection mode, thereby meeting a wider range of product needs.
[0028] Specifically, the female terminal 22 includes two spaced-apart spring connecting pieces 23, with connecting protrusions 24 on opposite sides of the two spring connecting pieces 23. The male terminal assembly includes a male terminal body 40, which is a groove-shaped block with an opening facing downwards and extending through both ends. A mounting block 41 is disposed within the groove of the male terminal body 40, and several male terminals 42 are spaced apart within the mounting block 41. The side of the male terminal 42 furthest from the female terminal is used to connect to the LED light strip, while the side of the male terminal 42 adjacent to the female terminal assembly is plate-shaped and used to mate with the female terminal 22. The male terminal 42 is inserted between the two spring connecting pieces 23 of the female terminal, with both sides abutting against the connecting protrusions 24, forming a knife-type contact between the male terminal 42 and the female terminal 22. This ensures stable contact and improves the electrical connection between the male terminal 42 and the female terminal 22.
[0029] Two snap-fit slots 30 are symmetrically arranged at both ends of the female end body 20, and a snap-fit block 50 is arranged at each end of the male end body 40 on the side adjacent to the female end component. In use, the male end component and the female end component are joined together by snap-fitting the snap-fit block 50 with the corresponding snap-fit slot 30.
[0030] In a specific configuration, the snap-fit groove 30 includes a first limiting groove 31 and a second limiting groove 32. The first limiting groove 31 is opened inward from the end face of the female end body 20 and is located in the lower part of the inner side of the end face. The second limiting groove 32 is opened inward from the end face of the female end body 20 and is located in the upper part of the outer side of the end face. The depth of the second limiting groove 32 is greater than the depth of the first limiting groove 31. An insertion interface 33 is provided on the side of the upper groove edge of the first limiting groove 31 near the male end assembly. The snap-fit block 50 includes an L-shaped protrusion 51 and a second limiting block 52. The L-shaped protrusion 51 is disposed on the side of the groove wall of the male end body 40 near the female end body 20. A side plate 53 is provided on the outer side of the L-shaped protrusion 51. During assembly, the L-shaped protrusion 51 is inserted obliquely into the second limiting groove 32 from the insertion interface 33. After the horizontal part of the L-shaped protrusion 51 is fully inserted into the second limiting groove 32, the male end body 40 is rotated to make it horizontal. The male end body 40 and the female end body 20 are limited on both sides by the cooperation of the L-shaped protrusion 51 and the second limiting groove 32.
[0031] A first limiting block 34 is horizontally arranged within the second limiting groove 32. The first limiting block 34 is a trapezoidal block whose surface coincides with the bottom surface of the second limiting groove 32. A second limiting block 52 is located on the wall of the male end body 40 near the L-shaped protrusion 51. The second limiting block 52 is a pentagonal block, with its cross-sectional area on the side closest to the female end component being smaller than that on the side furthest from the female end component. When the L-shaped protrusion 51 engages with the second limiting groove 32, the male end body 40 rotates downward. The inclined surfaces of the first limiting block 34 and the second limiting block 52 engage, pressing the second limiting block 52 below the first limiting block 34 under pressure, thus limiting the vertical movement of the male end body 40 and the female end body 20. Through the engagement of the L-shaped protrusion 51 with the second limiting groove 32 and the engagement of the first limiting block 34 with the second limiting block 52, the male end body 40 and the female end body 20 are connected. After connection, the male end body 40 and the female end body 20 can move horizontally and tilt left and right within a certain range. Specifically, the male end body 40 can move 0.05mm in the horizontal direction relative to the female end body 20, and the male end body 40 can rotate 1.5° in the horizontal plane relative to the female end body 20, which is convenient for appropriate adjustment according to the use of LED light strips and the environment.
[0032] A further configuration includes a T-shaped groove 43 at each end of the male end body 40 on the side furthest from the female end component. A T-shaped block 44 is installed within each T-shaped groove 43, and a connecting plate 45 protrudes outward from the bottom end of each T-shaped block 44. The connecting plate 45 is used to connect with the LED light strip board, thereby achieving the connection between the male end body 40 and the LED light strip. A support strip 46 is provided at the bottom of the male end body 40 on the side of the T-shaped groove 43 near the female end component. When the male end body 40 is attached to the LED light strip board, the support strip 46 contacts the LED light strip board, preventing the male end body 40 from falling off the LED light strip board due to its center of gravity.
[0033] The female end body 20 has insertion slots 25 formed from the bottom surface inward at both ends, and two insertion blocks 11 are correspondingly provided on the female end fixing plate 10. The connection between the female end fixing plate 10 and the female end body 20 is realized through the cooperation of the insertion slots 25 and the insertion blocks 11.
[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
