The application of Yellow Rubber Seal O-Ring Automotive Connector in automotive connectors is crucial to ensuring the reliability of connectors in humid environments. The following is a detailed explanation of how to ensure its reliability from the aspects of material selection, design principles, manufacturing process, installation and maintenance.
1. Material selection
Rubber material: Yellow Rubber Seal O-Ring Automotive Connector usually uses silicone rubber material. Silicone rubber has excellent weather resistance, high temperature resistance, low temperature resistance and chemical stability, and is particularly suitable for harsh environments such as humidity and corrosion.
Hardness selection: Hardness is an important factor affecting the sealing performance of the sealing ring. To ensure that the sealing ring has sufficient elasticity and can maintain a good sealing effect under pressure.
2. Design principles
Groove design: The size and cross-sectional area of the groove must be adapted to the deformation of the sealing ring. The design principle is that the cross-sectional area of the groove is larger than the cross-sectional area of the sealing ring to ensure that the sealing ring can be completely accommodated in the groove after compression to form an effective seal.
Compression control: The compression of the sealing ring is a key factor affecting the sealing effect. Generally controlled between 18% and 25%, with a maximum of no more than 30%. When used in a low temperature environment, the compression should be designed to 30% as much as possible to ensure the sealing effect of the sealing ring.
3. Manufacturing process
Raw material mixing: The silicone rubber material and processing aids are mixed evenly and pre-treated by a mixer to ensure the plasticity and processability of the rubber material.
Molding: Use appropriate molds to mold the rubber material to form an O-ring.
Vulcanization: Stabilize the rubber through vulcanization to improve the durability and sealing performance of the sealing ring.
4. Installation and maintenance
Correct installation: When installing the sealing ring, ensure that the groove and sealing surface of the sealing ring are clean and smooth to avoid scratching the sealing ring. At the same time, ensure that the sealing ring is installed in place to avoid insufficient or excessive compression.
Regular inspection: During use, the state of the sealing ring should be checked regularly. If aging, deformation or damage is found, it should be replaced in time.
Avoid chemical corrosion: During storage and use, the sealing ring should be kept away from chemical substances such as acids and alkalis to avoid chemical corrosion.
In summary, through reasonable material selection, design principles, manufacturing process, and installation and maintenance measures, the reliability of Yellow Rubber Seal O-Ring Automotive Connector in automotive connectors can be ensured, thereby ensuring the normal operation of the connector in a humid environment.
