Crimper for non-insulated terminals…
Their crimping part, which is actually clamped onto the wire, happens for several sections, that is, with different lengths (or heights) of crimp whiskers, and with different widths of these same whiskers. “Large” terminals, for large wire sections (from 1.5 mm2 and above, up to about 4) look like in the photo above, small ones, https://tonaton.co.tz/s_31-compactor-trucks for which the monitored crimper is intended, are below. You can clearly see the difference in the width of the crimp whiskers. But for Dupont, JST and other "computer-electronic" need another, even smaller. The old one is 4mm, the new one is 6.5mm (or so) There is a slight difference in width, but this may be a feature of a particular model of a particular manufacturer. I experimented – unfortunately not very successfully, which I also wrote about, in particular, in a recent review of diamond drills, where I tried to modify the dies from the crimper so that they would normally crimp. But for small ones, such as “lyre” and smaller ones, the overlooked one is irreplaceable. And finally, I got a crimper, which is inexpensive and perfectly compresses the terminals. This is an important fact for the selection of alternative dies, but it does not affect the quality of the crimp in any way. A short summary is a great thing, especially for 10 bucks. Automotive terminals have a crazy assortment.
First, perhaps, briefly about the terminals and crimping as a process. The following slaaaid… shows the difference between terminals for different sections. if I’m not mistaken, these are 1.5 and 2.5mm2. For large terminals and large wire cross-sections it will not work, you need something else, larger. On the deceitfulness of the first impression
A wire of a smaller cross section can be folded in half, although this is wrong, but if you really want to, then in principle you can. In this case, you need to remember: the wire cross-section, the size of the crimp part of the terminal and the size of the matrix must match each other, otherwise there will be no high-quality crimp. I hope that this part has clearly explained for which terminals this crimp is needed, and for which it is not suitable, let’s move on to the main part. A brother, but not a twin. There are many more types of non-insulated terminals, but IMHO this crimper is suitable for all automobiles for a small wire section. The result will be shown in the photo at the end of the review. Overviewed crimper is the brother of https://jiji.ug/169-travel-bags/black my old and beloved, bought on tinydeal many years ago.

I have several reviews of terminals and other connectors, and EVERYONE asks me the question "where can I get a good crimper?" They differ in the thickness of the matrices. Again, I don’t have a solution yet, because I bought mine offline a long time ago, but somehow I didn’t like what I bought in China at all and there’s nothing to recommend for buying.
