|
RG-59 |
3/16″ (0.187″) |
|
RG-6 |
1/4″ (0.25″) |
Step 2: Strip the Outer Jacket
Use a coaxial cable stripper or a utility knife to carefully remove the outer jacket of the cable. Insert the stripper’s blade into the jacket and gently twist it around the cable. Avoid damaging the inner shield or conductors.
Stripping Tips
Use a sharp blade to ensure a clean cut. Avoid pulling or stretching the cable while stripping it to prevent fraying or damage to the conductors.
Identifying the Center Conductor
The center conductor is the central wire of the coaxial cable, and it carries the signal. To identify it, follow these steps:
- Cut the cable end perpendicular to its length, using a sharp knife or cable cutter.
- Strip about 1/2 inch of the outer jacket from the end of the cable, exposing the braided shield and the dielectric insulation.
- Trim the ends of the braided shield so they are even with the end of the jacket.
- Gently pull back the dielectric insulation to expose the center conductor. The center conductor is typically made of copper or aluminum and is usually solid or stranded.
Be careful not to nick or cut the center conductor when stripping the cable.
Preparing the Shield for Termination
Once the center conductor is prepared, the next step is to address the shield. This involves removing the outer jacket and preparing the shield for termination.
Materials Required:
| Tool | Purpose |
|---|---|
| Wire strippers | Remove outer jacket |
| Diagonal cutters | Trim shield wires |
| Pliers | Flatten shield wires |
Steps:
- Strip the outer jacket: Using wire strippers, carefully remove about 1 inch (2.5 cm) of the outer jacket from the end of the cable. Be careful not to cut into the shield or center conductor.
- Trim the shield wires: Inspect the shield and look for any uneven wires. Using diagonal cutters, trim any excessively long or protruding shield wires so that they are approximately even with the cut edge of the jacket.
- Flatten the shield wires: Use pliers or a flat tool to flatten the shield wires against the core of the cable. This will create a smooth, even surface for soldering or crimping during termination.
Crimping the Connector
4. Crimping the Connector:
After preparing the cable, you’ll need to crimp the connector onto it. Here’s how:
- Insert the cable into the connector: Slide the prepared cable end into the connector body. Ensure the copper conductor is inserted fully into the center pin, and the braid is against the outer shell of the connector.
- Position the connector into the crimping tool: Place the connector into the appropriate crimping tool, aligning it with the corresponding die. The tool may have different dies for different connector types, so refer to the tool’s instructions for proper alignment.
- Crimp the connector: Squeeze the tool’s handles firmly to crimp the connector onto the cable. Apply enough pressure to secure the connection without damaging the cable or connector.
