These connectors have a ring of solder inside, which melts when a heat gun is used to heat. The heat shrink also shrinks to secure the joint, as well as internal hot melt adhesive to provide a water resistant seal. It is an easy way of soldering two cables together without the worry of solder dripping onto upholstery.
To use :
- Slide the connector to one side of the two wires that you wish to connect together
- Remove approx 1cm of flex from each side of the cable to reveal the metal strands
- Twist the metal strands from both wires together
- Slide the connector so that the ring of solder is located in the centre of the joint
- Ensure that the heat shrink will cover the entire joint
- Heat the joint up gently with a heat gun (follow usual precautions of ensuring the heat doesn't melt anything behind where you are making the joint). Ensure you move the joint/heat gun so that it is heated evenly all around
- Check the connection to ensure that it is secure and you can see the solder has melted across the metal strands inside the joint
