Description

Technical Field

[0001] This utility model relates to the field of LED light strip technology, specifically to a connection structure for LED light strips. Background Technology

[0002] LED light strips are linear lighting devices that integrate LED light sources onto flexible or rigid strip-shaped substrates. In other words, LED light strips refer to LEDs assembled on a flexible, strip-shaped circuit board, named for their strip-like shape. They are primarily used for decorative and functional lighting. However, in actual field use, LED light strips often need to be joined together due to insufficient length. Workers typically connect the joints of two LED light strips by twisting them together and using multiple layers of insulating tape. This process is cumbersome, and because the LED light strips are frequently bent in the environment, the joints are prone to breakage due to repeated bending, posing a safety hazard. Therefore, the jointed LED light strips have certain drawbacks in normal use. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] like Figure 1-7As shown, this utility model provides a technical solution: a connection structure for an LED light strip, including a connecting protective sleeve 4, with LED light strips 1 inserted into both ends of the connecting protective sleeve 4. A protective sleeve 2 is fixedly fitted onto the surface of the LED light strip 1, and a terminal block 3 is fixedly installed at the end of the protective sleeve 2. Two wires of the LED light strip 1 pass through the terminal block 3, and the ends of the wires of the LED light strip 1 extend to the outside of the terminal block 3. An insulating connecting plug 5 is provided inside the connecting protective sleeve 4. Two protective sleeves 14 are provided inside the connecting protective sleeve 4. The edges of the two protective sleeves 14 are pressed into contact with the end faces of the two protective sleeves 2, and the inner rings of the two protective sleeves 14 are respectively fitted onto the surface of the two terminal blocks 3. Through the arrangement of the protective sleeves 14... This allows the nylon cable tie 15 to provide support to the inner wall of the protective sleeve 4 when it is compressed and squeezed in the annular groove on the surface of the protective sleeve 4. This ensures the nylon cable tie 15 is stably compressed within the annular groove of the protective sleeve 4. The surface of the protective sleeve 4 is deformed by the compression, and the inner wall of the protective sleeve 14 is squeezed, causing the protective sleeve 14 and the inner wall of the protective sleeve 4 to be compressed and deformed inwards. This reduces the inner diameter of the two compressed points of the protective sleeve 4, trapping it between the two protective sleeves 2. This securely fastens the protective sleeve 4 to the outer ring of the joint between the two LED light strips 1, thus providing a stable cover for the joint. The protective sleeve 14... The compression fitting has two top support seats 13, the other end of which is fixedly connected to the surface of the insulating docking block 5. The top support seats 13 ensure that when the two positioning blocks 6 at the top and bottom of the insulating docking block 5 are inserted into the two junction boxes 3 for fixed installation, the top support seats 13 successfully engage the protective flexible cylinder 14 within the annular groove of the docking protective flexible cylinder 4. This allows the annular groove of the docking protective flexible cylinder 4 to provide mutual support to the nylon cable tie 15 during tightening and compression. The surface of the docking protective flexible cylinder 4 has two annular grooves, and the nylon cable tie 15 is fitted inside these grooves. The inner ring of the cable tie 15 is pressed into contact with the protective flexible cylinder 4. Wiring holes are provided at the top and bottom of the insulating docking block 5. Two copper strips 8 are installed inside the insulating docking block 5. The ends of the two wires of the LED light strip 1 are inserted into the wiring holes of the insulating docking block 5. The copper strips 8 ensure that the wires inserted into the insulating docking block 5 are electrically connected. Positioning blocks 6 are fixedly installed at the top and bottom of the insulating docking block 5. The two positioning blocks 6 are respectively inserted into the grooves on the surface of the two wiring cylinders 3, and positioning bolts 7 are inserted into the front of the wiring cylinders 3. Positioning holes for use with the positioning bolts 7 are provided in the middle of the positioning blocks 6, and the middle of the positioning bolts 7 passes through the positioning holes in the middle of the positioning blocks 6.Furthermore, the surface of the positioning bolt 7 is threadedly connected to the inner wall of the connector sleeve 3. Fastening push rods 10 are inserted into both sides of the connecting protective flexible sleeve 4. The surface of the fastening push rod 10 is threadedly connected to the surface of the connecting protective flexible sleeve 4. A positioning block 11 is rotatably connected to one end of the fastening push rod 10 located inside the connecting protective flexible sleeve 4. The side of the positioning block 11 inserts into a slot on the side of the insulating connecting plug 5. By driving the fastening push rod 10 and the positioning block 11, the rotation of the fastening push rod 10, utilizing the threaded advancement principle, causes the positioning block 11 to engage in the slots on both sides of the insulating connecting plug 5, thus ensuring proper alignment. The protective sleeve 4 is positioned on the outer ring of the insulating mating block 5 and fixed vertically. A turntable 12 is fixedly installed at one end of the fastening push rod 10 outside the protective sleeve 4. The turntable 12 has a cross-shaped groove on its side for easy rotation. The turntable 12 facilitates the rotation of the fastening push rod 10. A fastening rod 9 is inserted into the front of the insulating mating block 5. The surface of the fastening rod 9 is threaded to the inner wall of the insulating mating block 5. The fastening rod 9 presses and fixes the connector inserted into the wiring hole of the insulating mating block 5, allowing electrical connection through the internal copper strip 8.

[0021] In use, first, completely cover the protective sleeve 4 onto any one of the LED strips 1. Then, place the two protective sleeves 14 onto the outer ring of the connecting tube 3 of the two LED strips 1. Next, remove the insulating docking block 5 and insert the terminals of the two LED strips 1 into the corresponding terminals of the insulating docking block 5. Rotate the corresponding fastening rod 9 using the external cross-shaped cutter, so that the fastening rod 9, through the threaded push principle, presses the terminals tightly into the inside of the insulating docking block 5 and squeezes them together with the copper strip 8, thus connecting the two LED strips 1. Then, insert the positioning blocks 6 at the top and bottom of the insulating docking block 5 into the connecting tubes 3 of the two LED strips 1, and then connect and position them using the positioning bolts 7. Fix the insulating docking block 5 between the two LED strips 1 to be connected. Then, slide the protective sleeve 4 on the LED strip 1 to cover the docking point. (See the instruction manual attached.) Figure 4As shown in the diagram, the external cross blade rotates the turntables 12 on both sides, causing the fastening push rod 10 to rotate. The threaded push of the fastening push rod 10 drives the positioning block 11 to engage in the slots on both sides of the insulating docking block 5. Then, the two nylon cable ties 15 are fitted into the annular grooves on the surface of the docking protective cylinder 4 and tightened, causing the surface of the docking protective cylinder 4 to be deformed. The inner wall of the cylinder compresses the inner protective cylinder 14, causing the inner wall of the protective cylinder 14 to be compressed and deformed inwards. This reduces the inner diameter of the two compressed points of the docking protective cylinder 4, trapping it between the two protective sleeves 2. This securely secures the docking protective cylinder 4 to the outer ring of the two LED light strips 1, providing stable protection for the docking point. All content not described in detail in this specification is prior art known to those skilled in the art.

[0022] In summary, the connection structure of this LED light strip involves inserting the connecting wires of the two LED light strips 1 into the wiring holes of the insulating mating block 5, and then pressing them together with the threaded fastening rod 9 to fix them onto the copper strip 8 inside the insulating mating block 5. This connects the connecting wires of the two LED light strips 1 through the copper strip 8, thus establishing the connection between the two LED light strips 1. Subsequently, the positioning blocks 6 at the top and bottom of the insulating mating block 5 are inserted into the wiring sleeves 3 of the two LED light strips 1, and the positioning bolts 7 are used for connection and positioning. The device is fixedly installed between two LED light strips 1 to be connected. It works in conjunction with the fastening push rod 10 to drive the positioning block 11 to lock into the slots opened on both sides of the insulating docking plug 5. The nylon cable tie 15 is wrapped around the surface of the docking protection soft cylinder 4 to tighten it. The docking protection soft cylinder 4 is stably wrapped around the docking point of the two LED light strips 1. That is, the docking protection soft cylinder 4 protects the docking area of ​​the insulating docking plug 5, thereby strengthening the connection strength of the docking point whether it is pulled outward or pressed and bent inward. As a result, the LED light strips that have been docked can be used stably and normally for a long time.
