If the wings aren't crimped properly, just crimp them again in a smaller cavity. I usually crimp them twice by default and it works like a charm every time. Much easier then trying to fix them with regular pliers.

Straight to the point and well laid out. Thank you klsir!

“Take a look at these wires that you should’ve used instead.” 🤣 Alright, broseph. You’re right; I’m just gonna go with the pre-assembled ones from now on. Thanks!

Hanging the wings off the shelf is the hot tip here. I'm a molex baby so I had no idea what to do without a locator. I still think the locator is worth every penny though

I find it easier to hold the pin lightly in the jaws (usually one click) and then pull it through until it limits on the shelf. This saves you dropping the pin. To strip the right length of insulation I have mounted a spare pin on a piece of wood and use that to to check the length of the stripped wire. I use silicon insulated 24 AWG wire, you can strip this with your finger nails, no chance of nicking any of the strands of wire! My crimpers don't crimp the insulation properly either, a right PITA.

Evidently this crimper does /not/ have proper dies for DuPont and Mini-PV connectors, as the female die on it is designed to fold the tabs back on to the wire, whereas the DuPont design uses a circular shape instead. Thus, why your crimped terminal didn't fit in to the housing. Also, while I'm struggling atm to find documentation of this, it seems the SN-28B is also not appropriate for JST connectors, as those need a 4mm deep die, whereas the 28B's dies are 7mm deep - so you can't even use them for a single-operation crimp without crushing either the connector-side or the insulation-side. I'm feeling really frustrated that this stuff is evidently so difficult to get right. It really doesn't make sense to me. Even if these aftermarket crimps are cloning the OEM tooling, what prevents them from actually copying the geometry exactly?? How are they fucking up these critical details? Really sucks that it seems you actually have to pay hundreds to get proper tooling that works.

SN-025 gives correct shape crimp on the insulation for dupont terminals

@michael.a.covington 4 ай бұрын

Yes. I use an SN-025 for DuPont and SN-01BM for JST. SN-28B seems to be mostly for larger terminals, although the smallest slot in it ought to work. But I see it's not properly tightening up the part that grips the insulation. The SN-025 does.

Currently shopping for crimpers. Looks like SN-025 is the model to use for dupont terminals, it gives the correct round crimp on the insulation clamp and B crimp on the conductor.

Excellent video, mate!

Thanks a lot!

The trouble with those pre-made cables is that they have individual single pin connectors, which you advise against. So do you recommend buying them, removing the single shells and replacing them with the appropriate shell for the number of ways you actually need?

@davidmalawey Жыл бұрын

Yes exactly. Purchase the housing (shell) with the appropriate number of positions. And if you just buy 2, 3,4, then save cash. For example, use 2 pieces of 3 pins to get a 6 pin connector - it's far better than singlets.

You can buy pre-crimped leads with no housings applied.
