Common terminology used in connectors
Source: | Author:smartkonn | Published time: 2018-07-02 | 1629 Views | Share:
1. Connector: A detachable component (except an adapter) that is typically attached to a cable or device for electrical connection to the transmission line system.

2. RF connector: A connector used in 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 thousand HZ and 3000 GHz.

5. High frequency: Radio waves with a frequency range between 3 MHz and 30 MHz.

6. Coaxial: The inner conductor has a medium support, which is structurally capable of obtaining the smallest internal reflection coefficient in the frequency range in the measurement.

7. Triax: A transmission line consisting of three layers of concentric conductors with a common axis and insulated from each other.

8. Grade: 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 that is manufactured with the widest tolerances (tolerances), but still guarantees minimum specified performance and interoperability.

Note: The requirements of the reflection coefficient may or may not be specified.

10. High-performance connector (level 1): A connector that specifies the reflection coefficient limit value according to the frequency change. Generally, the specified dimensional tolerance is not stricter than the corresponding 2-level connector, but it is necessary to ensure that the connector satisfies the reflection coefficient. When required, the manufacturer is responsible for selecting tighter tolerances.

11. Standard Test Connector (Level 0): A precision-made, specific type of connector used to measure the reflectance of Class 1 and Class 2 connectors. The error caused by the measurement results is negligible.

Note: Standard test connectors are typically part of an adapter between different types, and the adapter is connected to a precision connector to form part of the test equipment.

12. Seal

12.1 Sealed Connector: A connector that meets the specified gas, moisture or liquid tightness requirements.

12.2 Barrier Seal: Prevents the seal from entering the interior of the connector housing with gas, moisture or liquid in the axial direction.

12.3 Panel Seal: Prevents gas, moisture or liquid from entering the seal between the mounting or adapter housing and the panel through the mounting holes.

Note: Seals are usually supplied as stand-alone products.

12.4 Insert Face Seal: A seal that prevents gas, moisture or liquid from entering the interface of a pair of mating connectors.

12.5 Air Seal: Meets the seal required by Test Qk in IEC 60068-2-17 "Basic Environmental Test Procedures Part 2: Test - Test Q: Seal".
