Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead technology, specifically to an LED lamp bead connection structure. Background Technology

[0002] In LED lighting equipment, the connection structure between LED beads and PCB board is a key part to ensure the normal operation of the lamps. With the widespread application of LED technology in the lighting field, such as urban lighting projects and indoor lighting, higher requirements are placed on the stability and maintainability of LED beads. A reliable connection structure can not only ensure that LED beads emit light stably, but also facilitate installation and replacement to adapt to different usage environments and equipment upgrade needs. Therefore, it is essential to develop an efficient, stable and easy-to-maintain LED bead connection structure.

[0003] However, existing LED chip connection structures have many shortcomings. Some structures rely solely on soldering to connect the pins to the PCB board, lacking physical fixation. Under environments such as vibration and high temperature, the LED chips are prone to loosening, leading to pin breakage or electrical connection failure. Other connection methods involve cumbersome installation steps, requiring complex tools or professional skills. Replacing LED chips is time-consuming and labor-intensive, increasing maintenance costs. In addition, some structures are not designed to protect the LED chips, failing to effectively withstand external impacts and reducing the lifespan of the LED chips. They are unable to meet the stability and convenience requirements of modern lighting equipment. Therefore, we propose an LED chip connection structure. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-6 An LED bead connection structure, comprising:

[0026] PCB board 1 and LED lamp bead body 2. The top end face of PCB board 1 has multiple sets of equally spaced sockets 8, and the top of PCB board 1 is provided with LED lamp bead body 2. The bottom of LED lamp bead body 2 is provided with pins 13, and the pins 13 are connected to the sockets 8.

[0028] Furthermore, the PCB board 1 has a rectangular plate structure. The top end face of the PCB board 1 has four sliding holes 7 arranged in a ring array on the side corresponding to the 8 sets of insertion holes. The sliding holes 7 penetrate the PCB board 1. The bottom four corners of the PCB board 1 are provided with positioning cylinders 6, and the four corners of the PCB board 1 are provided with connection holes corresponding to the positioning cylinders 6. The pins 13 on the top of the PCB board 1 are easy to be inserted into the insertion holes 8, and the soldering ensures the quality of electrical connection.

[0029] Furthermore, a set of connecting blocks 12 arranged in a ring array are provided on the outer side of the LED lamp bead body 2. The connecting blocks 12 have a trapezoidal strip structure and play a role in connection and limiting.

[0030] Furthermore, the auxiliary connection assembly includes a fixing member 3, an elastic member 4, and a support base 5. The bottom of the auxiliary connection assembly is the support base 5. Multiple fixing members 3 and elastic members 4 are evenly distributed inside the top of the support base 5, with the fixing members 3 placed inside the elastic members 4. After the four corners of the support base 5 are connected to the PCB board 1 via adapter screws, the fixing member 3 moves axially along the inner cavity 11 by pressing the top contact block 19 at the bottom of the fixing member 3. During the movement, the elastic member 4 is continuously compressed, and the fixing ring 14 at the top of the fixing member 3 separates from the PCB board 1, placing the LED bead body 2 inside the fixing ring 14. During the placement of the LED bead body 2, the connecting blocks 12 on its side wall are misaligned with the fixing block 17. After adjusting the bottom pin 13 of the LED bead body 2 into the socket 8, the top contact block 19 is released. The compression and rebound force of the elastic element 4 causes the fixing element 3 to reset. At this time, the fixing groove 18 at the bottom of the fixing block 17 engages with the connecting block 12 to complete the position connection of the LED bead body 2. This effectively prevents the LED bead body 2 from shaking and prevents the bottom pin 13 of the LED bead body 2 from breaking due to shaking, thus improving the protection of the pin 13.

[0031] Furthermore, the support base 5 has a rectangular plate structure, and each of the four corners of the top of the support base 5 is provided with a positioning post 9. The positioning post 9 is inserted into the positioning cylinder 6, and the top shaft end of the positioning post 9 is provided with a second connection hole. The second connection hole and the first connection hole are connected by an adapter screw. The top of the support base 5 is provided with multiple mating cylinders 10 that are evenly distributed. The top and bottom ends of the mating cylinder 10 are both circular opening structures. The inner cylindrical wall of the mating cylinder 10 is an inner cavity 11. The positioning post 9 and the positioning cylinder 6 can realize the quick positioning and connection of the support base 5 and the PCB board 1. The inner cavity 11 of the mating cylinder 10 is an auxiliary connection between the fixing part 3 and the elastic part 4 to improve the effective space.

[0032] Furthermore, the fixing component 3 includes a fixing ring 14, a sliding rod 15, and a mating plate 16. The fixing ring 14 and the mating plate 16 are concentrically aligned. Four sliding rods 15 arranged in a circular array are welded between the fixing ring 14 and the mating plate 16. The sliding rods 15 are slidably connected to the sliding holes 7, and the mating plate 16 is slidably connected to the inner wall of the inner cavity 11. The bottom of the mating plate 16 is provided with a top contact block 19. The sliding connection between the sliding rods 15 and the sliding holes 7 effectively ensures the stability of the fixing component 3 during movement and prevents the fixing component 3 from rotating.

[0033] Furthermore, the fixing ring 14 is circular and is placed at the top of the PCB board 1. The inner wall of the ring 14 has four fixing blocks 17 arranged in a ring array. The fixing blocks 17 have a trapezoidal plate structure and a fixing groove 18 at the bottom. The fixing groove 18 is engaged with the connecting block 12. The trapezoidal plate structure of the fixing blocks 17 can be quickly aligned with the trapezoidal structure of the connecting block 12 to improve the connection speed.

[0034] Furthermore, the elastic element 4 is placed inside the inner cavity 11, and the bottom of the elastic element 4 is attached to the top of the mating plate 16, while the top of the elastic element 4 is attached to the top of the inner cavity 11. The elastic element 4 is always in a compressed state inside the inner cavity 11, which effectively ensures the connection quality of the fixing block 17 to the LED lamp bead body 2.
