Introduce

A cable gland connector gasket is a sealing device used in cable connectors to ensure the connection’s seal with the external environment. They are often positioned at the interface of a cable connection to prevent liquids, gases, and contaminants from entering the connector while also protecting it from external conditions.

Technical data

Tensile strength 7-20 MPa
Elongation 200-600%

Certification standard

  • Material standards: Commonly used materials for cable gland connector gasket include elastic materials such as EPDM rubber. These rubber materials must meet the corresponding national and industry standards, such as the technical requirements and test methods for rubber materials stipulated in GB/T 528, GB/T 3856 and other relevant standards.
  • Dimensional tolerance standards: The dimensional tolerances of gaskets need to comply with the tolerance levels and dimensional requirements of elastomer O-rings and other seals stipulated in standards such as GB/T 3285.
  • Electrical performance standards: Due to the special use scenarios, gaskets must have good insulation resistance and voltage resistance levels. You can refer to GB/T 11996 and other standards for testing.
  • Environmental adaptability standard: Based on the temperature, humidity, chemical pollution and other factors in the use environment, select materials that meet the environmental test requirements of GB/T 528 and GB/T 3856 for thermal aging, low temperature, oil pollution and other items.
  • Safety standards: The materials and finished products of cable gland connector gasket need to meet the corresponding Restriction of Hazardous Substances (RoHS) and other environmental and safety directive requirements.
  • Quality management system standards: Manufacturing companies usually need to obtain quality management system certifications such as ISO 9001 to ensure that products and services meet quality requirements.

Advantage

  1. The cable gland connector gasket has a very good sealing effect, which can effectively prevent liquids and gases from entering the interior through the gaps in the cable interface and protect the electrical contact of the connector.
  2. It has excellent electrical insulation properties and can play a good insulation role to ensure electrical safety.
  3. The cable gland connector gasket also has a long service life. It is made of high-quality rubber material and has the advantages of wear resistance and aging resistance.
  4. The installation is very convenient and quick, with package design and matching connectors.
  5. It has good compression elasticity and can absorb the slight displacement and tolerance caused by the connector being vibrated.
  6. Low price and cost effective to use.

Function

  1. Sealing protection: The cable gland connector gasket can effectively prevent moisture, dust and other foreign matter from entering the connector, and protect the contact points inside from corrosion.
  2. Insulating electrical function: It has good insulation performance, which can effectively cut off current leakage and ensure electrical safety.
  3. Buffer compensation function: cable gland connector gasket can absorb the slight displacement and tolerance of the connector to avoid poor contact.
  4. Anti-loosening and fixing effect: By compressing both ends of the connector, the stability and reliability of the connector can be greatly increased.
  5. Beautiful and decorative effect: Packaged design makes the connector look neater and more beautiful.

Conclusion
