Commonly used professional terms in the connector industry

1. Connector: A detachable component (excluding adapters) typically installed on cables or equipment for electrical connection in transmission line systems. 2. RF connector: It is a connector used within the RF range. 3. Video: Radio waves with a frequency range between 3HZ and 30MHz. 4. Radio frequency: Radio waves with a frequency range between 3 kHz and 3000 GHz. 5. High frequency: Radio waves with a frequency range between 3MHz and 30MHz. 6. Coaxial: The inner conductor has a dielectric support, and the structure can obtain the minimum internal reflection coefficient within the frequency range during measurement. 7. Triple coaxial: A transmission line composed of three concentric conductors with a common axis and insulated from each other. 8. Level: The level of mechanical and electrical precision of the connector, especially in terms of the specified reflection coefficient. 9. Universal connector (Level 2): A connector manufactured with the widest allowable dimensional deviation (tolerance) while still ensuring the minimum specified performance and compatibility. Note: The requirement for reflection coefficient can be specified or not specified. 10. High performance connector (Level 1): A connector that specifies the limit value of reflection coefficient based on frequency variation. The size tolerance specified is usually not stricter than that of the corresponding Level 2 connector, but when it is necessary to ensure that the connector meets the requirements of reflection coefficient, the manufacturer has the responsibility to choose a stricter tolerance. 11. Standard Test Connector (Level 0): A precision manufactured specific type of connector used for measuring the reflection coefficient of Level 1 and Level 2 connectors, with negligible errors caused by measurement results. Note: Standard test connectors are usually part of different types of adapters, while adapters are connected to precision connectors to form part of the testing equipment. 12. Sealing 12.1 Sealed connector: A connector that meets the specified gas, moisture, or liquid sealing requirements. 12.2 Barrier seal: A seal that prevents gas, moisture, or liquid from entering the interior of the connector housing along the axial direction. 12.3 Panel sealing: prevents gas, moisture, or liquid from entering the seal between the fixed or adapter housing and the panel through the mounting holes. Note: Seals are usually provided as standalone products. 12.4 Sealing of mating surfaces: A seal that prevents gas, moisture, or liquid from entering the interface of a pair of mating connectors. 12.5 Gas seal: A seal that meets the requirements of Test Qk specified in IEC60068-2-17 "Basic Environmental Test Procedures Part 2: Tests - Test Q: Seals". 13 connectors in stock: goods that exist on the market and can be directly matched without the need for factory reproduction.
