It helps if you have fine stranded wire to use a fine point needle nose pliers or tweezers to grip the back of the contact when inserting it into the contact housing connector to get it seated. The cheaper ones didn’t even have a forming/dimpling bump in the top of the jaw as shown in the pictures above, where the terminals are formed to curl back down and into or across the wire being crimped. Efficient Crimping Tool] Crimping tools use exceptional crimping dies and efficient ratchet mechanisms.

I just solder wires onto the pins and apply heat-shrink insulation, which just feels so wrong, like I’m missing something important. To the extent that your personal data is processed on the grounds of your consent, you have the right to withdraw that consent. I liked the IWISS tool so I purchased their PEX pipe crimp tool, another winner, I can get into areas my other tools can’t.I have used the bigger tool for a number of years, and found that the best way to set up a crimp is to place the empty connector into the ralative position in the jaw, correctly positioned so that the two sets of prongs are properly placed in the positions where they will roll. But I was surprised to see what he said about the PA09, I would guess poor tolerance on the terminals or excessive wear on the tool. I find it faster to just reduce the width of the terminal; if that doesn't work then the wire is too thick for the tool anyway.

for JUST the connector sizes in a Duet connector pack, everything I'm saying is probably not relevant and an iWiss style is probably fine. Then you will discover that there are tons of youtube videos that “show” you how to crimp JST connectors, and that most of them are absolute crap, particularly if you are 50 years old can barely see the freaking crimp connectors. Finalize crimp by giving it another good firm tug test, and if needed it’s handy to have an eye loupe magnifying glass around to provide a visual inspection, watching for any loose stranded wires or improperly seated crimps.Our long-term vision is to provide everyone with precision pliers and matching parts by offering one-stop product solutions for crimp connections to achieve fast and accurate crimping work. Insert your stripped wire, give it a satisfying squeeze and the resulting crimp will hug the wire strands and insulator perfectly every time. If you need to do a fair bit of crimping of JST type connectors, or Dupont, then this tool is definitely worth the investment.

If there any voids present, then corrosion can occur causing resistance and excessive heat which damages the electrical connection. Also, an additional (hard learned) tip: feel free to go all hulk on crimping the bare wire wings (the first crimp), but use a gentler touch with the second crimp, especially with solid core wire. What makes this crimper so easy to use compared to other inferior crimping tools is its rachet action which allows for a slow steady action, just what you need when dealing with little wires. Use the end of the crimper to bend the out wings in just a little bit so that it can fit into the crimp tool. The handles cannot be opened until a full crimping cycle is achieved therefore preventing partial crimps.The crimps are a bit hard to make and there is this inherent assumption everywhere that you should have just “known” how to do this.
