Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, specifically a quick plug for LED beads. Background Technology

[0002] As crucial light-emitting components in lighting, indicator, and display devices, the installation method of LED chips significantly impacts the stability of electrical connections and the ease of maintenance. Currently, the main connection methods for LED chips include soldering and standard plug-in connections, but these methods have certain limitations in practice.

[0003] 1. Traditional soldering connections require the use of soldering irons or automatic soldering equipment for fixing, which is cumbersome and difficult to operate. In addition, once the LED beads are damaged or need to be replaced, the disassembly and resoldering process is time-consuming and labor-intensive, making it unsuitable for applications that require frequent replacement of LED beads.

[0004] 2. While existing conventional plug-in connections can avoid the tediousness of soldering, they lack a stable limiting structure and are prone to loosening or poor contact of terminals due to external vibration, increased insertion and removal times, or environmental changes, which can affect the normal operation of LED beads.

[0005] 3. In addition, the plug terminals of LED plugs in the prior art are usually designed in a straight line. After the LED is inserted, the contact pressure between the terminal and the LED pin is small, resulting in high contact resistance, which in turn affects the conductivity, increases power loss, and may even cause LED flickering or unstable electrical connection.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A quick-connect plug for LED beads includes an insulating substrate and a bent first electrical terminal and a second electrical terminal. The two ends of the insulating substrate are respectively connected to form a plug interface that matches the first electrical terminal and the second electrical terminal. A plurality of limiting blocks are formed on the outside of the insulating substrate. One segment of the first electrical terminal and the second electrical terminal are respectively engaged at the plug interface through the plurality of limiting blocks.

[0009] Preferably, a section of the first electrical terminal and a section of the second electrical terminal are in an I-shape and are respectively engaged at the fitting interface by several limiting blocks.

[0010] Preferably, a portion of the bent first electrical terminal and a portion of the bent second electrical terminal are each U-shaped.

[0011] Preferably, one end of the connector is formed with a rounded corner that matches the U-shaped bend.

[0012] Preferably, a section of the first electrical terminal and a section of the second electrical terminal are respectively formed with elongated holes, and a section of the first electrical terminal with the elongated holes and a section of the second electrical terminal are bent to form a guiding slope.

[0013] Preferably, the conductivity resistance between the first electrical terminal and the second electrical terminal is between 5mΩ and 50mΩ.

[0014] Preferably, the first electrical terminal and the second electrical terminal are respectively a positive terminal and a negative terminal.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. The present invention provides a quick plug for LED lamp beads, which forms an interface matching the first electrical terminal and the second electrical terminal through an insulating substrate, thereby ensuring quick installation and reliable electrical connection of LED lamp beads.

[0017] 2. The limiting blocks set on the outside of the insulating substrate in this solution, and the part of the terminal that is connected by the structure between the limiting blocks, make the electrical terminals firmly mechanically fixed at the plug interface, preventing loosening or poor contact. This can effectively improve the convenience of plugging and unplugging LED beads, realize solderless installation, and is suitable for quick replacement and maintenance.

[0018] 3. Secondly, the bending design of the first and second electrical terminals in this solution allows the LED beads to undergo elastic deformation when inserted, providing stable contact pressure, reducing contact resistance, and improving conductivity, thereby enhancing the electrical reliability and lifespan of the LED beads.

[0026] 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.

[0027] Please see Figures 1-5 As shown, a quick-connect plug for LED beads includes an insulating substrate 1, and bent first electrical terminals 2 and second electrical terminals 3. The insulating substrate 1 has conductive interfaces 11 at both ends that match the first electrical terminals 2 and the second electrical terminals 3. A plurality of limiting blocks 12 are formed on the outside of the insulating substrate 1. A portion of each of the first electrical terminals 2 and the second electrical terminals 3 is respectively engaged with the interfaces 11 through the limiting blocks 12. By forming the interfaces 11 on the insulating substrate 1 to match the first electrical terminals 2 and the second electrical terminals 3, reliable electrical connection for quick installation of LED beads can be ensured. The limiting blocks 12 on the outside of the insulating substrate 1, and the structure between the limiting blocks 12 engaging one end of the limiting terminals, keep the electrical terminals firmly mechanically fixed at the interfaces 11, preventing loosening or poor contact. This effectively improves the convenience of inserting and removing LED beads, enabling solderless installation and facilitating quick replacement and maintenance. Secondly, the bending design of the first electrical terminal 2 and the second electrical terminal 3 in this solution enables the LED bead to undergo elastic deformation when inserted, providing stable contact pressure, reducing contact resistance, and improving conductivity, thereby enhancing the electrical reliability and lifespan of the LED bead.

[0028] Preferably, a portion of the first electrical terminal 2 and a portion of the second electrical terminal 3 are H-shaped and respectively snapped together at the fitting interface 11 by a plurality of limiting blocks 12. The H-shaped design of a portion of the first electrical terminal 2 and a portion of the second electrical terminal 3 forms a stable mechanical support at the interface 11, and the snapping and fixing by the limiting blocks 12 ensures that the terminals are tightly fitted within the interface 11, preventing loosening or displacement due to vibration or increased insertion / removal cycles. Furthermore, the H-shaped structure of this design allows the terminals to provide a larger contact area, which helps to enhance contact stability, reduce contact resistance, and improve conductivity, thereby ensuring the reliability of the LED lamp bead electrical connection.

[0029] Preferably, a portion of each of the bent first electrical terminal and the second electrical terminal is U-shaped. This U-shaped design of the first electrical terminal 2 and the second electrical terminal 3 provides elastic deformation capability when the LED bead is inserted, ensuring stable contact pressure, a tight and reliable electrical connection, and reducing loosening and poor contact caused by vibration or increased insertion / removal frequency.

[0030] Preferably, one end of the insertion interface 11 is formed with a rounded corner 11U that matches the U-shaped bend U. By forming a rounded corner 11U that matches the U-shaped bend U at one end of the insertion interface 11, the electrical terminals can be smoothly inserted, reducing the insertion force and preventing the terminals from deforming or being scratched due to hard contact. At the same time, it improves the stability and consistency of the insertion.

[0031] Preferably, a section of the first electrical terminal 2 and the second electrical terminal 3 is further formed with an elongated hole H, and a section of the first electrical terminal 2 and the second electrical terminal 3 with the elongated hole H is bent to form a guiding slope S. By forming an elongated hole H in a section of the first electrical terminal 2 and the second electrical terminal 3, and providing a guiding slope S at the bend, the terminals can provide buffer elasticity when the LED bead is inserted, reducing the insertion force and preventing the terminals from deforming or breaking due to excessive rigid insertion and removal force.

[0032] Preferably, the conductive resistance between the first electrical terminal 2 and the second electrical terminal 3 is between 5mΩ and 50mΩ. By controlling the conductive resistance between the first electrical terminal 2 and the second electrical terminal 3 to between 5mΩ and 50mΩ, the electrical connection of the LED bead is ensured to have low contact resistance, thereby reducing power loss, improving current transmission efficiency, and avoiding problems such as heat generation, energy loss, or voltage drop caused by excessive resistance.

[0033] Preferably, the first electrical terminal 2 and the second electrical terminal 3 are the positive terminal and the negative terminal, respectively. By setting the first electrical terminal 2 and the second electrical terminal 3 as the positive terminal and the negative terminal, respectively, the polarity connection of the LED bead is clearly defined, preventing circuit failures or damage to the LED bead due to reverse polarity connection, and improving the safety and stability of the electrical connection.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
