Description
Technical Field
[0001] The utility model relates to the field of lamp beads, and more specifically to a patch lamp bead for a leather wire lamp. Background Art
[0002] The colorful leather wire lamp uses built-in IC colorful lamp beads to connect on three wires. The color of each lamp bead can be controlled by the controller to achieve a colorful effect. The leather wire lamp is soft and waterproof, with a large light-emitting angle. It is easy to use and is widely popular in the field of colorful lamp decoration. The usage will continue to increase in the future, gradually replacing the original light string application, and because of the point control function, more other DIY markets will be added. However, the built-in IC colorful leather wire lamp beads on the market currently have planes between adjacent pins on the lamp beads, and there is no limit structure to limit the wires. This will cause the wires to be easily biased when they are mounted on the pins. Therefore, the lamp beads have higher requirements for the accuracy of the patch, which increases the difficulty of patching. In addition, when soldering after patching, the melted solder paste is easy to overflow on the plane between adjacent pins, resulting in tinning, causing adjacent pins to short-circuit, resulting in product scrap and reducing the production efficiency of the lamp beads.
[0003] The utility model with authorization announcement number CN218160432U relates to the technical field of lighting components, specifically a new type of patch colorful lamp beads suitable for leather wire lamps, including a shell, a number of pins fitted on the shell, and a number of insulating protrusions provided on the shell, wherein the insulating protrusions are provided between adjacent pins so that adjacent pins are spaced apart. The utility model uses insulating protrusions to separate adjacent pins, which can play a limiting role when the wires and pins are patched to prevent the wires from sticking unevenly, and can isolate the solder paste between the pins when the wires and pins are welded to prevent the pins from being tinned together and causing a short circuit.
[0004] In the above-mentioned disclosed structure, the pins are separated by providing insulating protrusions, which not only causes the surface of the lamp bead to be uneven, which is not conducive to fitting and positioning, and is easy to peel off and separate from the skin wire, resulting in poor stability, but also is not conducive to the drainage of solder paste during welding and fitting, affecting the welding strength and conductive stability. The overflowed solder paste is also likely to cause multiple pins to short-circuit, and the adaptability is poor, which needs to be improved. Utility Model Content
