This is a new type of connection that a few of our customers recommended to us, so we decided to stock. We still prefer to use solder on our own connections, but we have had a play with these and have managed to make some very strong, secure connections. 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.

To use :

1. Slide the connector to one side of the two wires that you wish to connect together
2. Remove approx 1cm of flex from each side of the cable to reveal the metal strands
3. Twist the metal strands from both wires together
4. Slide the connector so that the ring of solder is located in the centre of the joint
5. Ensure that the heat shrink will cover the entire joint
6. 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
7. Check the connection to ensure that it is secure and you can see the solder has melted across the metal strands inside the joint

We still prefer the old fashioned method of solder and adhesive lined heat shrink, but these may suit some people who wish to avoid soldering.
