You’ve used our pre-terminated jumper wires before right? But sometimes they’re not the correct length or colour so what to do? Crimp! Crimping a wire and connector is a basic wire work skill that anyone can do with the correct tools. In this blog post I’ll explain how to use our crimp tool, connectors and housings we also have a video in this post so you can see the crimp in motion. What you need:
Wire – stranded is best, if using solid wire you’re best to solder the connector rather then crimping.
So why can’t you just use a hammer or a pair of pliers? Basically when crimping a connector to wire you are looking to get the best possible connection with no gaps, if you have gaps the possibility of the crimp coming away from the wire increases as does the possibility of corrosion from trapped moisture. So using a quality crimp tool designed for the crimps you are using ensures the best possible electrical and mechanical connection.
How to crimp like a pro:
Firstly you need to strip the outer sheath of the wire, exposing about 5mm of wire and twist the bare wires together so they are nice and straight.
Next you need to take a crimp pin and place it between the jaws of the tool
leaving the end of the connector recessed about 1mm from the edge of the jaw
click the ratchet 3 times to hold the pin then offer the bared end of the wire to the back of the connector pin so the plastic sheathing will be held by the tabs when crimped.
Now squeeze the tool until the pin is fully crimped, it should look like this
Next simply push the pin through the housing ensure that the lock is lined with the clip and push until it goes "Click".
