5.3. Crimping Process (Step-by-Step)
Follow these steps for proper crimping of network or telephone connectors:

Abbildung 5.3: Detailed Crimping Steps. This visual guide shows the entire process from unlocking the tool to the final crimp, including cutting the cable skin, arranging wires, inserting the load bar, assembling the plug, inserting the plug into the tool, ensuring proper seating, and crimping.
- Unlock First: If the tool is locked, unlock it by squeezing the handles and releasing the lock tab.
- Cut the Skin: Use the integrated stripping blade to carefully cut and remove the outer jacket of the cable, exposing the internal wires.
- Ordnen Sie die Drähte an: Untwist and straighten the individual wires. Arrange them according to the desired wiring standard (e.g., T568A or T568B for Ethernet).
- Put the Load Bar (if applicable): For some connectors, a load bar is used to hold the wires in place. Insert the wires into the load bar in the correct order.
- Stecker zusammenbauen: Carefully insert the arranged wires (with or without load bar) into the RJ45 or RJ11/RJ12 connector, ensuring each wire reaches the front of the connector and is in the correct pin slot.
- Put Plug into Tool: Insert the assembled connector firmly into the appropriate crimping slot (8P for RJ45, 6P for RJ11/RJ12) on the tool.
- Ensure Pushed to the End of Holes: Verify that the connector is fully seated in the tool's slot and that the wires are pushed completely to the end of the connector's pins.
- Crimp Plug: Squeeze the handles of the crimping tool firmly and completely until the ratchet mechanism releases. This ensures a full and proper crimp.
- Beenden: Remove the crimped connector from the tool. Inspect the crimp to ensure all pins are properly seated and the cable is securely fastened.
