![]() ![]() ![]() ![]() Inspect the crimp (the book I link below shows what various crimps should look like), and pull gently on the wire, holding the terminal in your other hand. Then squeeze until the crimper completely closes and the ratchet releases so you can open it again. Next, put the stripped wire into the terminal, making sure it's at the right depth and that the insulation ends at the right spot. My basic technique is to put the terminal into the die and squeeze the crimper just enough to hold it in place. A good crimp cold welds the wire to the terminal and should require pounds of force (at least a firm pull) before the wire pulls out. It tells me that the die you have is not made for that terminal. If you find that you're having to "pre-crimp" anything before you can get the terminal into the die, then that's a problem. That said, I have had fairly good luck with some cheap crimpers, but it's hit and miss. Crimp dies have to be made specifically for the terminal to work ideally and wire length and wire insulation thickness are critical. Any recent advice on that one.Ĭrimping is a far more specialized and precise operation than it appears at first glance.įirst, the problem could be that your crimpers aren't very good. Then again, a very tiny difference may do the trick. It looks very much like the one I have but it is different. The question is: Do I have the right connectors and crimper? Is there a tip that someone might provide to help me do this better?īefore posting a similar topics panel was displayed showing this tool: Preciva Dupont Crimping Tool AWG26-18 That was much easier, but probably more expensive than what I have now. We had to use a specific wire striper to get the striped length exactly right. The crimpers we used there were such that it was held flat, the pin/socket dropped into a round hole in the center, the wire inserted, and when squeezed, the crimper came in from four sides and crimped both the insulation and the conductor. It covered soldering, crimping, wire-wrapping and other such skills. It does not get to the point where that little plastic finger clicks down and makes it stay in.Ī long time ago, while on active duty, I attended a technician’s school run by NASA people. And then, one of the connectors did not seat in the connector, meaning it can easily be pulled out. That means I must use the pliers again to post crimp and be sure the connector will not fall off. Then after crimping, I had wires slip out. When bringing the wire, connector, and crimper all together I have to use small needle nose pliers to pre-crimp the little fingers on to the insulator before I can get the wire and socket/pin into the crimper. The problem is certainly in part me and the tremors in my hands, but, I might have the wrong parts. The two pictures show the box of connectors I purchased and the crimper ordered at the same time. I am building some wiring for an Arduino UNO, probably the same for all of the Arduino products. ![]()
