de enige manier om een ​​fatsoenlijke krimp uit te voeren op kleine connectoren

Zoals met vrijwel alle krimptangen voor Dupont en JST connectoren, geldt ook bij deze dat het een kwestie van oefening, geduld en nauwkeurig werken is om goede krimpverbindingen te maken. En er zit absoluut verschil in kwaliteit tussen de ene en de andere krimpmat. Over het algemeen lukt het me om goede en betrouwbare verbindingen te maken met deze IWISS-3220M krimptang.

na een korte inloopperiode wordt deze ratelkrimptang een handige stuk gereedschap. Een beschrijving van het gebruik van de tang zou handig zijn.

I wasn’t sure what to expect, but it’s better than I hoped. Worth every penny.

I tested this on the Molex SL crimp contacts (for the 0.100" square headers) and JST XH contacts (the typical LiPo battery balance connector) on 22AWG PVC wire. The 1.6mm opening works with the Molex SL and 2.0mm MOSTLY works with the JST XH. The caveat with the JST XH is that the insulation grips are crimped to be slightly too wide to fit into the crimp housing so you have to take a pair of pliers and ever so slightly squish it sideways. I looked at the crimps under a microscope and both the conductor and insulation fingers looked neatly and cleanly rolled for both types of contacts.I did pull tests but don't have a force scale nor the official pull-force test pliers from Molex. What I did was pull on the connector in a vise until the wire came out and then pulled on a luggage scale in the vice until it felt the same. I don't know what the JST XH spec is but the Molex SL spec is 8.82lbs for 22AWG. Therefore I used that specification for both connectors. My test runs for the Molex SL resulted in 50%, 75%, and 150% of the specified pull force. The test runs for the JST XH resulted in 50%, 60% and 100%. I am not sure how consistent the official crimper would be.I should also add that even though it does not have a positioner like the official tools, the die is of the proper thickness for the both Molex SL and JST XH so all you have to do is line up the end of the crimp (wire-side) with the edge of the die. So no need to position the crimp contact midway in the die.The parallel jaws and EDM cut die make a huge difference for these tiny contacts where any mos-positioning of the crimp terminal in the die, or inaccuracy in the die matters a lot more. The parallel jaws come straight down on the crimp contact which makes crimping much less of a hassle because the crimp terminal is much more likely to stay in position. With plier-type crimpers, the hinged jaws roll and tilt the crimp contact as it comes down. You can get away with a little tilt in larger contacts but with tiny contacts a little tilt throws things off a lot more and destroys the crimp.So other than having no positioner and needing a second slightly squeeze from the side for the JST XH contacts, you save But other than that it works at saves $500+ from the official crimp tools.

Plus petite que je n'imaginais, mais conforme.A l'air solide et précise. A tester en condition réelle.

Köpte den till JST SH men behövde till PicoBlade, visade sig att tången skall passa båda +++
