what is Oval Rubber Grommets
Oval rubber grommets are a type of rubber product used for the protection of wires, cables, and electrical appliances. It is made of high-quality rubber, which is not easy to crack, or break, flexible, fold-resistant, and wear-resistant.
Another important feature is its double-sided design. This design allows the grommets to protect in both directions, increasing the security of wires and cables.
Protection principle
1. Support and stability: The oval rubber grommets provide stable support for wires and cables through their design structure. It can form a closed ring around the wires and cables to ensure that the wires and cables can be effectively supported in any direction and prevent them from being damaged by bending, twisting, or stretching.
2. Buffering and impact absorption: When wires and cables are impacted by external impacts, rubber grommets can absorb and disperse the impact force. Because its rubber material has elasticity and buffering properties, it can effectively reduce the impact of wires and cables and protect them from damage.
3. Anti-wear and protective insulation: The design of the oval rubber grommets can reduce friction between wires and cables and the external environment. It provides a layer of protection against abrasion, friction, or punctures, extending the life of wires and cables and ensuring their safety.
Classification
1. Closed type: This type of rubber grommet is closed and has only one opening for passing wires and cables through the grommet. Its advantage is that it can provide better protection to prevent wires and cables from being affected by the external environment, such as friction, impact, and ultraviolet rays. Additionally, closed grommets prevent small animals or other foreign objects from getting inside the grommets, thus avoiding potential safety issues.
2. Open type: This type of rubber grommet is open and can pass wires and cables through from one side, and then folded up to pass through from the other side. Its advantage is that it is easy to install and disassemble, and can easily adapt to different sizes of wires and cables. However, the protective effect of open-type grommets is relatively poor because their structure is relatively simple and cannot provide as comprehensive protection as the closed type.
