The structure of the arrow-shaped plastic tie (fixed with oval hole) is different from that of the round-hole fixed tie. This type of plastic tie can prevent the wire harness from twisting after the installation is completed, and it is effective for the environment where the direction of the wire harness needs to be strictly limited. It is better, after the installation is completed, there is a strong fixed stability.
The installation holes of the fir-tree plastic tie are also round holes. The thickness of the sheet metal suitable for the fir-tree type is relatively large, ranging from 7 to 8 mm. The type of the matching hole can be a through hole or a threaded blind hole. From the perspective of reducing the number of clips, the fir tree type can be used first, but in terms of mold design, the fir tree type is more complicated than the arrow type, and the cost is about 10% higher. If it is installed from bottom to top during use, it is recommended to use an arrow-shaped plastic cable tie. After it is inserted, the two sides will open, and it will not fall off for a long time, and the fir tree type has the risk of falling off under severe vibration.
