Definition of Rubber Wire Protection Grommet
Rubber wire protection grommet, also called rubber cable grommet, is a wire protection device made of rubber materials (such as natural rubber, nitrile rubber, silicone rubber, EPDM rubber, etc.), mainly used to protect wires or cables. The design principle is to clamp the wire guard ring on a metal plate or other hard material, so that the wire can pass through safely, avoiding being cut or worn by sharp edges. It has the characteristics of dust prevention, water resistance, wear resistance, corrosion resistance, and insulation.
Material and Characteristics of Rubber Wire Protection Grommet:
Material: The main materials of rubber wire protectors include natural rubber, nitrile rubber (NBR), silicone rubber, and ethylene propylene diene monomer (EPDM). These materials each have unique properties such as high temperature resistance, low temperature resistance, corrosion resistance, oil resistance, etc., which can be selected according to specific application environments. For example, silicone rubber has outstanding high and low temperature resistance, can maintain good elasticity in the temperature range of -70 ℃ to+260 ℃, and is resistant to ozone and weather aging.

Characteristics: The rubber grommet has excellent wear resistance, corrosion resistance, and insulation performance. It can protect wires from physical damage and chemical corrosion in harsh environments, thereby extending the service life of wires and improving the safety of electrical systems.
Shape and selection of rubber wire protection grommet:
The most commonly used rubber wire grommets are circular and perforated;
Elliptical with diaphragm in the middle.
When choosing wire protection covers, please focus on the dimensions of GD&GW, as they match the hole size and thickness of the metal plate.

Application and installation of rubber wire protection grommets:
The application range of rubber wire protectors is very wide, mainly used in various electronic and electrical equipment to protect wires from being cut by metal plates, while also playing a role in dust prevention, waterproofing, and insulation. Specific application scenarios include:
Power supply: Rubber grommets are commonly used at the outlet of power supplies to protect wires from cuts from metal plates.
Control box: In the control box, rubber cable grommets are used to protect the wires and prevent them from being cut.
General power cord outlet: At the outlet of various power cords, rubber wire protectors are used to protect the wires and prevent them from being cut.
Electronic devices: Rubber wire grommets are also widely used in electronic devices, such as distribution boxes and chassis outlets, to protect wires from scratches.
Sports equipment: Rubber cabel grommets are also used in sports equipment to protect wires from damage.
Furniture and lighting fixtures: Rubber wire grommets are used at the wire outlets of furniture and lighting fixtures to protect the wires from being cut or worn.
These application scenarios demonstrate the importance and diversity of rubber wire protectors in various devices and systems.
Installation: The installation of rubber grommet is relatively simple. Usually, simply clip the wire guard ring onto the reserved metal hole and thread the wire through it. Ensure that the protective wire loop is tightly integrated with the metal plate to achieve the best protection effect
Advantages of Rubber Wire grommet:
Protecting wires: Rubber grommets can effectively prevent wires from being cut by metal edges, avoiding electrical system failures caused by wire damage
Improving safety: By protecting wires, rubber wire grommets can help reduce safety hazards such as electrical fires and electric shocks
Extended service life: The wear resistance and corrosion resistance of rubber geommets can extend the service life of wires and reduce maintenance costs.
