The main advantages of using the plastic inner frame of the plug include:
Insulation: The plastic inner frame of the plug is made of insulating material, which can effectively protect the metal parts inside the plug and avoid dangerous situations such as short circuit or electric shock when power is on.
Stability: The plastic inner frame of the plug has good stability and impact resistance, which can ensure that the plug is not easy to loosen or fall off during use, improving the safety of use.
Corrosion resistance: The plastic inner frame of the plug is generally made of engineering plastics, which has good corrosion resistance and can resist the erosion of various chemical substances and extend its service life.
Environmental protection: The plastic inner frame of the plug is recyclable and meets environmental protection requirements.
Easy to produce: The plastic inner frame of the plug is produced by injection molding process, which has high production efficiency and relatively low cost.
In short, the plastic inner frame of the plug has the advantages of insulation, stability, corrosion resistance, environmental protection and ease of production, and is a relatively common plug protection device.
