haisstronica 6PCS Crimping Tool Set - Ratchet Wire Crimping Tool for Heat Shrink,Insulated Nylon,Non-Insulated,Ferrule Wire End,Open Barrel Terminals,Solar Connectors

Perfect for heatshrink connectors. Consistent crimp even with some of the lower quality heat shrinks which is rare (snap on crimpers don't crimp the cheaper heat shrinks tight enough sometimes) and it won't tear through the insulation either.The rubber grip is comfortable and ratchet is smooth. Good tool for a low price.

Successfully attaching spade connectors has eluded me for some time. There are a number of You Tube videos which are in conflict as to how these tools are used. Having bought what seemed to be the full range of tools for connectors I realised the key is to understand the very substantial difference between 'insulated' and 'non insulated' spade connector approaches. This is tool is for 'non insulated' as the name implies no hard plastic red, blue or yellow collars. One, make sure you have the correct connector for the wire to be connected. it's either mm2 or AWG - this tool is marked with both. I find AWG easiest to remember. Two, strip the wire sheath (use the correct tool) around a centimetre. Three, place the correct connector for the wire size into the marked jaw of the tool. Pull it through until it stops on the ridge of the internal jaw. (I give the tool a couple of click simply to pretension the connector in tool and stop it falling out). Four, feed the wire into the back of the connector until it stops (this is the insulation hitting the wire crimp). Five, squeeze the tool handles together - depending on what wire you are using it may feel quite stiff. The tool will release when once fully closed and you can pull the wire and connector out of the jaws. There should be the outer crimp holding the insulation, and the inner crimp holding the wire conductor. That's it!! You can buy isolators for these connectors for not much for a hundred (get the right size - and remember to slide them onto the wire first)...
