RF Feeder Connector Types
There are many types of RF feeder connectors, including direct-insert connectors, threaded connectors, and bayonet connectors. Direct-insert connectors are the most widely used. To use, simply insert the connector into the feeder core wire, requiring no tools or accessories. Threaded connectors require a wrench to tighten, while bayonet connectors require pliers to clamp the connector to the feeder wire. When choosing a connector, consider the feeder specifications and communication system requirements.
Welding Tips
1. Cleaning the Feeder Cable: Before soldering, insert the connector into the feeder cable and clean it with alcohol or detergent to ensure the contact surfaces are clean to avoid affecting communication quality.
2. Cutting the Feeder Cable: Before soldering the connector, use wire strippers to remove the insulation from the core and stranded conductors of the feeder cable, exposing the inner braid and center conductor.
3. Lifting the Braid: Lift the braid with pliers and roll it upward to expose the center conductor. Twist the braid to create a twist similar to a twist.
4. Connector Insertion: Insert the rolled metal braid into the connector and insert the feeder cable into the connector.
5. Connector Welding: Use an RF welder to weld the connector to securely connect the connector to the feeder cable. Carefully control the heating time and current during welding to avoid overheating and damage to the connector.
Connector Inspection Methods
After welding, the connector needs to be inspected for quality. The specific methods are as follows:
1. Visual Inspection: Visually inspect the connector to confirm that there are no burns or damage at the weld.
2. Communication Test: Use a communication tester to test the connector for communication performance to determine if it is susceptible to external interference or obstruction.
3. Electrical Parameter Test: Use a high-frequency tester to test the connector for electrical parameters, including VSWR (standing wave ratio) and loss, to assess whether the connector meets specified standards.
