📌 Primary Purpose
The main job of a crimping tool is to create secure, reliable electrical and mechanical connections by compressing a connector (terminal, plug, or socket) onto the end of a wire or cable.
🛠️ How It Works
Strip the insulation off the end of a wire.
Insert the wire into the metal barrel of a connector (like an RJ45 plug, ring terminal, spade terminal, etc.).
Place the connector into the correct crimping die on the tool.
Squeeze the handles — the tool compresses the metal around the wire, forming a permanent, low-resistance connection.
🔍 Types of Crimping Tools & Dies
Crimping tools can have different shapes and dies depending on the application:
🧰 Electrical Terminal Crimpers
For insulated and non-insulated terminals, like ring terminals and spade connectors.
Often have multiple jaw sizes for different wire gauges.
🌐 Network Cable Crimpers
🔋 Coaxial/Cable TV Crimpers
🪛 Ratchet Crimping Tools
📏 Key Features to Know
Crimping Dies: Replaceable or built-in shapes that match specific connectors.
Ratchet Handle: Ensures full compression and consistent crimps.
Ergonomic Grips: For comfortable use, especially for repetitive jobs.
Integrated Tools: Many network crimpers include a wire stripper and cutter.
⚙️ Common Uses
✔ Terminating Ethernet (RJ45) and phone cables (RJ11)
✔ Crimping spade, ring, butt, and blade terminals in automotive/electrical systems
✔ Installing coax connectors on cable/antenna wires
✔ Making custom cable assemblies
🧠 Benefits of Crimping vs Soldering
Faster and cleaner — no heat or solder needed.
Strong mechanical bond — excellent vibration resistance.
Consistent electrical connection when done right.
