DIY TRRS cable guide

日本語版

Kit contents

• TRRS plug * 2
• 4-core cable
• Paracord
• Cable sheath
• Heat-shrink tube * 2

Required tools

• Soldering iron
• Solder
• Solder wick
• Wire cutters
• Needle-nose pliers
• Cutter
• Masking tape
• A heat source like a heat gun

Other useful items:

• Polyimide tape (Kapton tape)

1: Remove the white thread from inside the paracord

2: Pass the 4-core cable through the paracord

3: Tape the edges of the paracord and cable with masking tape to prevent fraying

4: Pass the paracord-cable combination from step 3 through the cable sheath

    *Ensure that the cable sheath and paracord are tightly stretched around the cable

5: The cable sheath also frays easily, so hold it down with masking tape

6: Take off the metal housing from the 4-contact plug

7: Pass the result from step 5 through the metal housing and then the heat-shrink tubes

    *Ensure the screw threads on the metal housing point outwards as shown

8: Remove the masking tape from step 3 and cut the paracord and cable sheath to your desired length

9: Strip about 2cm of the grey covering from the 4-core cable

10: Strip each wire to match the lengths of each contact of the plug

     *Remember to take note of what color wire connects to which contact. In this photo, from shortest to longest contact, we solder green, white, yellow and brown.

11: Confirm once again that the metal housings and heat shrink tubes have been passed over the cable

12: Solder each of the wires to their contacts

    *Ensure you've taken note to match up the wire colors and contacts.

    *If you have heat-resistant polyimide tape, then wrap the top 2 contacts to prevent shorts

13: Close the base of the 4-contact plug

13: Confirm that the heat shrink tubes and metal housings are on the cable, and repeat the process on the other end

14: Using a multimeter, check that the contacts are matched correctly and that there are no shorts

15: Using a heat gun, shrink the heat shrink tubes, and screw on the metal housings to finish the cable

    *Remember to remove any masking tape you may have used in step 5 before you shrink the tubing
