Working with AMP connectors

[sparky961]

Does anyone know of a way to work with the pins in various connector shells without purchasing a $300 crimper (and probably more for each die head)?

Ok, so I have seen them for something like $150 (CAD) as well but that's also too much.

I have a few connectors that were cut off with about 2" of wire, which I can connect to, but I'd rather do it a bit cleaner than that by using fresh wires the correct length.

What is AMP connctor?

Does it has 6.3x0.8mm spade connectors? Like these:

http://www.tme.eu/gb/details/674.08.00.9/non-insulated-terminals/imp/

And stuff like this:

I found this one works pretty good for these non insulated "Abico" spade terminals:

Thre seems to be pretty many different type crimping pliers, most of the taiwan made seems to work for hobby use.

If you google HT-236C, you might find a local supplier. Many different "brands". Make sure you get the right crimpper for the terminals, there are surpricing amount of almost identical looking pliers and they are just a little different.

Hope this helps.

Sorry, I put up the original message on my way out.  Upon re-reading it I wasn't very clear in my request for info.

AMP is the manufacturer, but they make bazillions (yes, that's a scientific term) of different connector types.  I've attached pictures showing the two (M and F for each) that I'm currently working with.  Also some technical drawings.  Now that I'm looking at them again, the first isn't even "AMP", it's "Molex".  The second is AMP/Tyco

For the AMP/Tyco, part number molded on the shell is 206060-1.  The data sheet has information about a bunch of others in the series as well.

I was hoping to have a more generic solution that will work with others too but maybe I'm asking for too much there.  Maybe I can just butcher them with pliers ;) ?

For the circular Amp type I've always bought 'solder spill' contacts hence avoided the need to crimp. Slip a sleeve on the wire first, solder it then slip the sleeve over the exposed bit of contact.

For the Molex ones I bought the crimp tool from RS if I remember correctly

[sparky961]

Thanks, Andrew.  I didn't realize there were solder-type contacts for the round AMP connectors.  The terminals are usually the inexpensive part, it's the crimper that's generally pretty insane to buy.  I'll try that route for those.

I also looked into the price for crimpers for Molex and they weren't near as bad - though still a bit costly for occasional hobby use.  I was able to find some multi-purpose ones that looked decent so that might be the way I go there.

These are the ones I used on my servo driven 4th axis:

Oh, so the pins don't actually come out of the shell?  I have some SUB-D connectors like that.  Not bad to work with, but I was hoping to re-use the shells I have.  It isn't critical I do so, just trying to save a few bucks.

They may do perhaps with one of those tubular extractors - mine came fully populated - they are well made Chinese copies off ebay sold as 'circular military connectors'. Initially the seller cocked up the male / femaleness of the free cable plug / chassis socket, so I ended up with a few of the opposite 'orientation'

Here is an example:

Andrew - if the vendor's spec is right, and the part was 'on limit', is there a risk they might get a bit warm?

500 ohms insulation resistance - probably lost a k somewhere 

That wasn't necessarily the vendor I used - just an example off ebay, and they work just fine
