- Preparation:
– Strip the Cable: Prepare the LMR-100 cable by stripping it to expose the central conductor and shield. Follow these steps:
– Remove the Outer Jacket: Strip away the outer jacket to reveal the braided shield and dielectric insulation.
– Expose the Shield: Carefully remove the braided shield (or foil) without damaging it. Fold it back neatly to make contact with the connector’s grounding element.
– Strip the Dielectric: Strip the dielectric insulation to expose the central conductor. Follow the specifications for the correct strip lengths to ensure proper fitment.
– Prepare the Connector: Ensure the SMA female RP connector is clean and ready for assembly. It will include a central pin and a crimp ring or ferrule for the shield.
- Crimping Steps:
– Insert the Central Conductor:
– Insert the stripped end of the LMR-100 cable’s central conductor into the central pin of the SMA female RP connector. Ensure it is fully inserted and properly aligned.
– Crimp the Central Pin:
– Use a crimping tool to compress the crimp ring around the central pin. This creates a secure electrical and mechanical connection between the central conductor and the pin.
– Prepare the Shield:
– Fold back the braided shield of the LMR-100 cable so that it makes contact with the connector’s grounding element or body.
– Crimp the Shield:
– Slide the crimp ferrule (or ring) over the folded-back shield and use the crimping tool to compress it. This secures the shield to the connector’s grounding element, ensuring proper grounding and reducing signal loss. - Final Steps:
– Inspect the Connection: After crimping, check the connection to ensure it is secure. Verify that the central pin is correctly positioned and that the shield is adequately crimped. Look for any signs of damage or misalignment.
– Clean the Area: If necessary, clean the area around the connection with isopropyl alcohol or another suitable cleaning agent to remove any flux residue.
– Test the Connection: Use RF testing equipment if available to confirm that the assembly performs correctly and meets the required specifications for signal integrity and performance.
Applications:
– SMA Female RP to LMR-100 Crimped Assemblies are used in RF and microwave applications where reliable and secure connections are needed. The RP design helps prevent accidental mismatching with standard SMA connectors, which is important in RF systems to ensure correct connections.
– Crimping provides a robust and reliable connection, making it suitable for both field installations and manufacturing environments.
