从规格来看，它专为直径约3mm的圆线设计，适配线材卡槽宽度为7.5mm，整体长度为20.85mm，安装孔中心距14.5mm，安装孔直径3.3mm，可匹配标准M3规格的螺丝。产品高度7mm，底座厚度1.7mm，安装后不会占用过多设备内部空间，同时保证足够的结构强度。

产品采用白色阻燃尼龙或ABS塑料制成，绝缘性能优异，可有效避免电线与金属外壳接触短路，提升电气设备的安全性；弧形卡槽设计贴合线材轮廓，夹紧时不会压破电线绝缘层，对线材起到保护作用；双孔安装结构操作便捷，仅需螺丝即可快速固定在PCB板、机箱、设备面板上，无需复杂工具，同时能牢固限制线材位移，防止线材晃动拉扯导致焊点脱落、绝缘层磨损。

它的应用场景十分广泛，常见于家电、工控设备、灯具、DIY电子项目中，主要用于固定电源线、信号线，整理设备内部零散电线，避免杂乱布线，同时满足安规要求的线位固定，防止线材因摩擦、拉扯引发漏电或短路问题。

This product is the YG-21-3 White Plastic Cable Clamp, also commonly known as a saddle-type wire clip or cable retainer. It is a commonly used accessory for cable management and fixing in the electronic and electrical fields. Screws are not included with the product, so it needs to be installed with matching screws.

In terms of specifications, it is specifically designed for round wires with a diameter of approximately 3mm. The width of the cable slot that fits the wire is 7.5mm, the overall length is 20.85mm, the center distance between the mounting holes is 14.5mm, and the diameter of the mounting holes is 3.3mm, which is compatible with standard M3 screws. The product has a height of 7mm and a base thickness of 1.7mm, so it does not take up too much space inside the equipment after installation, while ensuring sufficient structural strength.

Made of white flame-retardant nylon or ABS plastic, the product has excellent insulation performance, which can effectively prevent short circuits caused by contact between wires and metal enclosures, improving the safety of electrical equipment. The curved slot design fits the profile of the wire, so it will not damage the wire insulation when clamped, protecting the wire. The two-hole mounting structure is easy to operate; it can be quickly fixed to PCBs, chassis, or equipment panels with just screws, no special tools are required. At the same time, it can firmly limit the displacement of the wire, preventing the wire from shaking and pulling, which may cause solder joints to fall off or the insulation to wear out.

It has a wide range of applications, commonly used in household appliances, industrial control equipment, lighting fixtures, and DIY electronic projects. It is mainly used to fix power cables and signal wires, organize scattered wires inside the equipment to avoid messy wiring, and meet the safety requirements for wire position fixing, preventing electric shock or short circuit problems caused by wire friction and pulling.
