Description

Technical Field

[0001] This utility model relates to the field of power supply terminal technology, and in particular to a light source terminal holder. Background Technology

[0002] With the continuous development of modern technology, LED strips are increasingly widely used. By precisely controlling the light color, brightness, and frequency of the LED strip, an ideal environmental atmosphere can be effectively created. Generally, LED strips are composed of multiple LEDs connected in series, giving them a certain length to wrap around or wrap around decorations, enhancing their visual effect. Terminal blocks are components used to connect LED strips and circuit boards. Traditional terminal blocks typically use a plug-in installation method. This method requires a large space on the circuit board for drilling and installing the terminal block, which is not conducive to miniaturized circuit board design and limits the overall size and appearance of the product. Furthermore, plug-in terminal blocks require manual insertion of the terminals into the holes on the circuit board. This process requires matching the pins of the terminal block with the holes on the circuit board one-to-one before soldering, making the operation complex and hindering production efficiency. Moreover, soldering is easily affected by human and equipment factors, leading to problems such as cold solder joints and desoldering, resulting in unreliable electrical connections and affecting the lifespan and performance of the LED strip. Finally, the size and pin layout of plug-in terminal blocks are relatively fixed, making it difficult to adapt to LED strips and circuit boards of different specifications and sizes, resulting in poor compatibility.
