Description

Technical Field

[0001] This utility model relates to the field of electrical connection element technology, specifically a novel light strip connector. Background Technology

[0002] LED flexible light strips refer to LEDs assembled on a strip-shaped flexible circuit board. The product looks like a strip. Because of its long service life, energy saving and environmental protection, it has gradually emerged in various decoration industries. Connectors are one of the important components of LED flexible light strips.

[0003] For example, Chinese patent application CN222581712U discloses an easy-to-assemble LED connector, which specifically includes a female connector and a male connector. Both the female and male connectors have rectangular electrical connection grooves, and a first electrical connection piece is provided in the rectangular electrical connection groove. The male connector has a push plate and a second electrical connection piece corresponding to the first electrical connection piece. A rotating shaft that drives the push plate is rotatably provided in the male connector. A knob is provided on the outside of the male connector, and the knob is connected to a rotating tube that drives the rotating shaft. The first electrical connection piece has a semi-circular groove, and the second electrical connection piece has a semi-circular protrusion. The female connector has an insertion groove and a connecting part with a connecting groove. The male connector has an insertion part that mates with the insertion groove and a hook-shaped connector that mates with the connecting groove. The male connector also has a circular groove, in which a rectangular limiting groove is opened. A rectangular limiting part that mates with the rectangular limiting groove is provided on the rotating tube. It achieves the clamping of conductive ends by rotating a knob to drive a multi-stage transmission structure, and achieves the fixed connection of male and female heads by hook-type connectors and insertion structures, providing a feasible solution for connecting LED light strips.

[0004] As the application scenarios of LED light strips continue to expand, the requirements for the structure, installation method, and adaptability of their matching connectors are becoming increasingly diversified. In different application scenarios, the arrangement, space constraints, and assembly requirements of light strips vary. A single-structure connector cannot fully cover the diverse usage needs. In order to further enrich the structural types of light strip connectors and provide the market with more differentiated choices to adapt to the connection needs of LED flexible light strips in different scenarios, this application proposes a new type of light strip connector.

[0006] To address the shortcomings of existing technologies, this utility model provides a novel LED strip connector. The housing, through an L-shaped locking plate at its end, forms a locking connection with the socket's limiting groove. This, combined with the embedded positioning connection between the bottom guide strip of the housing and the socket's guide groove, simplifies installation and disassembly. The through-hole and male connector are connected via a sliding fit. A hollow convex ring and a fixing block on the outer periphery of the male connector provide contact limiting, and a spring clip engages with the hollow convex ring. This bidirectional limiting structure effectively restricts male connector displacement, ensuring a stable connection between the insertion part and the socket pins.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a novel light strip connector, comprising two housings, each housing having a snap-fit ​​component, and each housing having at least two through holes extending through both ends, with a male connector disposed within the through holes, a plurality of fixing blocks disposed on the outer side of the end of the male connector, a hollow convex ring disposed on the inner wall of the middle part of the through hole, and an insertion part disposed at the other end of the male connector.

[0009] The male connector is provided with a limiting component on its outer side. The limiting component includes multiple spring pieces that can automatically spring up on the outer side of the male connector. After the spring pieces pass through the hollow convex ring, they spring open and abut against one side of the hollow convex ring. At the same time, the fixing block abuts against the other side of the hollow convex ring, thereby limiting the male connector in both directions within the through hole, so that after the insertion part is inserted into the corresponding socket, it can achieve stable docking with the pins in the socket.

[0010] The snap-fit ​​component includes an L-shaped snap-fit ​​plate disposed at the end of the housing, the end of the L-shaped snap-fit ​​plate being provided with a snap-fit ​​portion, and a groove being provided on the upper surface of the L-shaped snap-fit ​​plate on one side of the snap-fit ​​portion.

[0011] As a further preferred embodiment, the plurality of said spring pieces are evenly distributed along the circumference of the male head.

[0012] As a further preferred embodiment, the plurality of fixing blocks are evenly distributed along the circumference of the male head, and the number of fixing blocks is consistent with the number of spring pieces.

[0015] As a further preferred embodiment, each of the housings is provided with a socket on one side, and each socket is provided with a pin that corresponds one-to-one with the multiple insertion parts inside the corresponding housing.

[0016] As a further preferred embodiment, the bottom of the outer casing is provided with a guide strip, and the socket is provided with a guide groove that cooperates with the guide strip.

[0017] As a further preferred embodiment, the latching part is a latching block, with the side of the latching part near the socket having a slope that is lower on the left and higher on the right, so that the latching part slides against the inner top wall of the socket during the process of the outer shell and the socket fitting together.

[0018] As a further preferred embodiment, the top of the socket has a limiting groove, and the snap-fit ​​part is snapped into the limiting groove to fix the outer shell.

[0019] As a further preferred embodiment, a foolproof block is provided at the front end of the top of each of the two housings; one foolproof block is located on the left side of one housing and the other foolproof block is located on the right side of the other housing.

[0020] (III) Beneficial Effects

[0021] This utility model provides a novel LED strip connector. It has the following advantages:

[0022] This LED strip connector features a snap-fit ​​connection between the L-shaped locking plate at the end of the housing and the socket limiting groove. This, combined with the embedded positioning connection between the bottom guide strip of the housing and the socket guide groove, simplifies installation and disassembly. The through-hole and male connector utilize a sliding fit connection. The hollow convex ring and the outer peripheral fixing block of the male connector provide contact limiting, while the spring clip engages with the hollow convex ring.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-5 As shown, this utility model provides a technical solution: a novel light strip connector. The main body of the light strip connector includes two independent housings 4, which are used to support the connection structure of two sets of light strip wire harnesses respectively. It includes two housings 4, each housing 4 is provided with a snap-fit ​​member 10, and each housing 4 has at least two through holes 9 extending through both ends. The through holes 9 are used to accommodate male connectors 5 and provide installation space for them. The male connector 5 is provided in the through holes 9. Multiple fixing blocks 8 are provided on the outer side of the end of the male connector 5. A hollow protruding ring 11 is provided on the inner wall of the middle part of the through hole 9. An insertion part 6 is provided at the other end of the male connector 5.

[0031] The male connector 5 is provided with a limiting member 7 on its outer side. The limiting member 7 includes multiple spring pieces 12 that can automatically spring up on the outer side of the male connector 5. After the spring pieces 12 pass through the hollow convex ring 11, the spring pieces 12 spring open and abut against one side of the hollow convex ring 11. At the same time, the fixing block 8 abuts against the other side of the hollow convex ring 11, thereby limiting the male connector 5 in both directions within the through hole 9, so that after the insertion part 6 is inserted into the corresponding socket, it can achieve stable docking with the pins in the socket.

[0032] The snap-fit ​​component 10 includes an L-shaped snap-fit ​​plate 1 disposed at the end of the housing 4. The end of the L-shaped snap-fit ​​plate 1 is provided with a snap-fit ​​part 3. A groove 2 is provided on the upper surface of the L-shaped snap-fit ​​plate 1 and on one side of the snap-fit ​​part 3.

[0033] During assembly, the male connector 5 is inserted into one end of the through hole 9. As the spring piece 12 on the outside of the male connector 5 passes through the hollow convex ring 11, it contracts and deforms due to the pressure of the inner wall of the hollow convex ring 11, making it easy to pass through. After the spring piece 12 has completely passed through the hollow convex ring 11, it is no longer compressed and automatically springs open, with its end abutting against the side of the hollow convex ring 11 away from the fixing block 8. At the same time, the fixing block 8 at the end of the male connector 5 just abuts against the side of the hollow convex ring 11 near the fixing block 8, which limits the male connector 5 in both directions, restricting the displacement of the male connector 5 in the through hole 9, ensuring that the insertion part 6 of the male connector 5 can be stably inserted into the corresponding socket and form reliable contact with the pin in the socket. The L-shaped card plate and the snap-fit ​​part 3 at the end of the outer shell 4 are used to realize the fixed connection between the outer shell 4 and the socket. The groove 2 makes it easy for the snap-fit ​​part 3 to snap into the limiting structure of the socket and it can be used to cooperate with the inner wall of the socket.

[0034] Among them, multiple spring pieces 12 are evenly distributed around the male head 5. The even distribution of the spring pieces 12 around the circumference ensures that the male head 5 is subjected to balanced force when it is in the limit position, and avoids the male head 5 from tilting or deviating due to uneven force, thereby improving the limit stability.

[0035] Meanwhile, multiple fixing blocks 8 are evenly distributed along the circumference of the male connector 5, and the number of fixing blocks 8 is the same as the number of spring pieces 12. The fact that the number of fixing blocks 8 and spring pieces 12 is the same and that they are distributed circumferentially ensures that the limiting force on the male connector 5 in the through hole 9 is evenly distributed throughout the entire outer circumference, avoiding local stress concentration that could cause deformation of the male connector 5 or the hollow convex ring 11.

[0036] Furthermore, the hollow convex ring 11 and the through hole 9 are integrally formed, which avoids the fitting gap caused by independent assembly.

[0037] like Figure 2-3 As shown, the upper end of the longitudinal section of the hollow convex ring 11 is trapezoidal, with an inclined surface on the side facing the spring piece 12 and a rectangle on the other side. The end of the spring piece 12 abuts against the rectangular side of the hollow convex ring 11. Of course, the shape of the lower end of the longitudinal section of the hollow convex ring 11 corresponds to that of the upper end. When the male connector 5 is inserted into the through hole 9, the spring piece 12 first contacts the inclined surface of the hollow convex ring 11. The inclined surface provides guidance for the spring piece 12, allowing it to naturally contract under the insertion force, reducing the resistance when the spring piece 12 passes through the hollow convex ring 11, and achieving smooth assembly of the male connector 5. After the spring piece 12 has completely passed through the hollow convex ring 11, the spring piece 12 automatically springs open, and the flat surface of its free end abuts tightly against the rectangular surface of the hollow convex ring 11. The rectangular surface provides stable contact support for the spring piece 12, preventing the spring piece 12 from slipping due to the tilt of the contact surface, ensuring that the bidirectional limiting structure formed by the spring piece 12 and the fixing block 8 is reliable and effective, and the male connector 5 will not move axially within the through hole 9.

[0038] like Figure 1-3As shown, each housing 4 has a corresponding socket on one side, and each socket has a pin that corresponds one-to-one with the insertion part 6 inside the corresponding housing 4.

[0039] The bottom of the outer casing 4 is provided with a guide strip (not shown in the figure), and the socket is provided with a guide groove (not shown in the figure) that mates with the guide strip. When the outer casing 4 is assembled with the socket, the guide strip at the bottom of the outer casing 4 first inserts into the guide groove in the socket. The engagement of the guide strip and the guide groove is the mating of the outer casing 4 and the socket, which restricts the relative displacement of the outer casing 4 and the socket in the lateral direction. This ensures that the insertion part 6 of the male connector 5 in the outer casing 4 and the pin in the socket can be aligned in the correct direction, avoiding collision damage or poor mating of the insertion part 6 and the pin due to misalignment during assembly.

[0040] like Figure 1 As shown, the latching part 3 is a latching block 14. The side of the latching part 3 near the socket has a slope that is lower on the left and higher on the right, so that the latching part 3 slides against the top wall of the socket during the process of the outer shell 4 and the socket engaging.

[0041] A limiting groove 13 is provided at the top of the socket, and the snap-fit ​​part 3 can be snapped into the limiting groove 13 to fix the outer shell 4. When the outer shell 4 is pushed towards the socket for assembly, the inclined surface of the snap-fit ​​part 3 first contacts the inner top wall of the socket. As the assembly force is applied, the inclined surface slides relative to the inner top wall of the socket. The inclined structure of the inclined surface converts the axial force of the assembly into a slight elastic deformation force of the snap-fit ​​part 3, so that the snap-fit ​​part 3 can slide smoothly over the inner top wall of the socket, reducing the resistance during the assembly process and avoiding assembly difficulties caused by the snap-fit ​​part 3 getting stuck. At the same time, the guiding effect of the inclined surface ensures that the snap-fit ​​part 3 can slide accurately into the limiting groove 13 of the socket.

[0042] In addition, a foolproof plug 15 is provided at the top front end of each of the two outer casings 4; one foolproof plug 15 is located on the left side of one outer casing 4, and the other foolproof plug 15 is located on the right side of the other outer casing 4; furthermore, in order to achieve the foolproof effect, the shape of the insertion port on the two sockets must match the position of the foolproof plug 15. Therefore, the above arrangement can prevent workers from inserting the outer casing 4 into the wrong position.

[0043] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0044] In summary, during assembly, the male connector 5 is first inserted into the through hole 9 of the outer shell 4. When the spring piece 12 on the outside of the male connector 5 passes through the integrally formed hollow convex ring 11 in the middle of the through hole 9, it is guided and squeezed by the inclined surface of the trapezoidal cross section of the hollow convex ring 11, causing it to shrink and deform, ensuring smooth insertion. After the spring piece 12 has completely passed through the hollow convex ring 11, it automatically springs open and abuts against the rectangular surface of the hollow convex ring 11. At the same time, the fixing blocks 8 evenly distributed on the outer periphery of the end of the male connector 5 abut against the other side of the hollow convex ring 11, limiting the position of the male connector 5.

[0045] Subsequently, the outer shell 4 is connected to the corresponding socket. The guide strip at the bottom of the outer shell 4 is embedded in the guide groove inside the socket to provide guidance for the connection and prevent the insertion part 6 from being misaligned with the pin inside the socket. During the connection process, the locking block 14 on the L-shaped locking plate at the end of the outer shell 4 is pressed and slides against the top wall inside the socket through its left-low and right-high slope, so that the locking part 3 can smoothly slide to the limiting groove 13 at the top of the socket and be locked and fixed. At this time, the bottom surface of the groove 2 also fits against the upper inner wall of the socket, thereby realizing a stable connection between the outer shell 4 and the socket.

[0046] At this time, the insertion part 6 of the male head 5 connects with the corresponding pins in the socket to form a conductive path, thereby achieving reliable fixation and stable conductivity, and thus adapting to the usage needs of diverse scenarios.

[0047] During disassembly, only external force needs to be applied to slightly deform the L-shaped card plate 1, causing the card part 3 to disengage from the limiting groove 13. Then, the outer shell 4 and the socket are separated along the guide groove. Subsequently, the male head 5 is pulled in the opposite direction, and the spring piece 12 is compressed and contracted by the inclined surface of the hollow convex ring 11, so that the male head 5 can be taken out from the through hole 9, completing the wire harness separation. The whole process does not require complicated operation, taking into account both connection reliability and ease of disassembly and assembly.

[0048] This utility model is not limited to the above-described embodiments. If any modifications or variations to this utility model do not depart from the spirit and scope of this utility model, and if such modifications and variations fall within the scope of the claims and equivalent technologies of this utility model, then this utility model also intends to include such modifications and variations.
