2. Setup and Preparation

Before crimping, ensure you have the correct size terminal for your wire and a suitable crimping tool (e.g., a square casing pressure crimping tool).

Steps:

  1. Select the Correct Terminal: Refer to the Specifications section (Table 1) to match the terminal model (e.g., E0508, E1508) with your wire's cross-sectional area (mm² or AWG). The color of the terminal's insulation often corresponds to a specific wire size.
  2. Strip the Wire: Carefully strip the insulation from the end of your electrical wire, exposing the conductor. The stripped length should be approximately 8mm, matching the pure copper length of most terminals, or as indicated in the terminal's specific dimensions.
  3. Insert Wire into Terminal: Gently twist the exposed wire strands to keep them together. Insert the twisted wire into the metal tube of the selected tubular crimp terminal until the insulation meets the plastic collar of the terminal.

3. Operating Instructions (Crimping)

Follow these steps to properly crimp the tubular terminal onto your wire:

  1. Position the Terminal: Place the terminal, with the wire inserted, into the appropriate crimping slot of your crimping tool. Ensure the metal tube of the terminal is fully within the crimping jaws.
  2. Perform the Crimp: Squeeze the handles of the crimping tool firmly and completely until the crimping cycle is finished and the tool releases. This ensures a full and proper crimp.
  3. Inspect the Crimp: After crimping, remove the wire and terminal from the tool. Visually inspect the crimped terminal. It should have a square or trapezoidal shape, indicating a secure connection. Gently tug on the wire to ensure it is firmly held by the terminal and cannot be easily pulled out.

4. Maintenance

JONOW Tubular Crimp Terminals require minimal maintenance. Proper storage and handling will ensure their longevity and performance.

  • Storage: Store terminals in a dry environment, away from moisture and corrosive substances, to prevent oxidation of the tin-plated surface. Keep them organized by size and color to facilitate easy selection.
  • Handling: Avoid bending or deforming the metal tube before crimping, as this can affect the quality of the connection.
  • Tool Care: Regularly clean and maintain your crimping tool according to its manufacturer's instructions to ensure consistent and accurate crimps.

5. Troubleshooting

If you encounter issues during the crimping process, consider the following:

  • Loose Connection: If the wire pulls out easily after crimping, the terminal size might be too large for the wire, or the crimping tool was not fully closed. Re-evaluate the terminal size and ensure a complete crimp.
  • Damaged Wire Strands: If wire strands are cut or damaged during stripping, re-strip the wire to a clean section. Damaged strands can weaken the connection.
  • Deformed Terminal: If the terminal is excessively deformed or crushed after crimping, the terminal size might be too small for the wire, or the crimping tool setting is incorrect. Ensure the correct terminal size and proper tool adjustment.
  • Incorrect Tool: Using a crimping tool not designed for tubular terminals (ferrules) can result in poor connections. Always use a tool that creates a square or trapezoidal crimp for these terminals.

7. User Tips

  • Color Coding: The color of the terminal's plastic collar typically indicates its compatible wire size. Always double-check the printed specifications or a chart to ensure you are using the correct terminal for your wire gauge.
  • Crimping Tool Quality: Invest in a good quality crimping tool designed for tubular terminals. A proper tool is crucial for achieving secure and reliable connections, preventing loose wires and potential electrical hazards.
  • Pre-Twist Strands: For stranded wires, gently twisting the exposed copper strands before inserting them into the terminal can help prevent stray strands and ensure all conductors are captured within the terminal for a better crimp.
  • Test Connections: After crimping, always perform a gentle tug test on the wire to confirm the connection is secure. For critical applications, consider using a multimeter to check for continuity and proper resistance.
