Crimping tool for spade lugs.

[alomac]

I'm in a situation where I have to attach some spade lugs (the minature,
uninsulated type of the sort found in the old 605 phone plugs) to the end of
some wires.
I'd prefer not to solder it, as the finished product will have to operate in
conditions which are likely to degrade the joints over an extended period.
I've been looking for a tool with which to crimp the lugs into the wire, in
the fashion used on factory-made goods, but have been unable to find one.
Nothing in the Jaycar or DSE catalouges sounds like it will do the job -
going by the decriptions there.
Does anyone know where I can find such a beast?

Cheers,
al.

Thats a situation where soldering is the best approach.

You cant get corrosion in the crimped joint when its soldered.

The only time that soldering isnt such a good idea
is with stranded wire in a high vibration situation.
The solid soldered part can produce a fracture at the
junction between the solder and the unsoldered wire.

Even then, you'd normally be better off
supporting the wire back where its insulated.

I was under the idea that high/low fluctuations in temperature would
eventually crack the joints if it happens over a long enough time. I've seen
this happen in some old TVs and Macintosh (with integrated CRT) computers
where there wasn't adequate ventilation.

That can happen, but not in that particular situation.

Its normally seen when rather large things are soldered onto PCBs etc.

Yes, but thats not going to occur in your situation.

If it did, you wouldnt see soldered pins on connectors etc.

Access Communications http://www.accesscomms.com.au/Default.htm shows
the crimp tool for these terminals on p.15 of their catalogue.

Dick Smith's T 3528 lug crimper (also Tandy 640 0410) works
great. If possible the technique is to bend the stripped wire
back against the unstripped insulated wire and crimp the lug to
this stripped wire side up. Look in any 1980's car engine bay
to see how it's meant to be done.

Also sold slightly cheaper by Altronics Part Number T 1550

That's designed for the terminals with a round cylinder for the wire.

Those terminals he is talking about arent like that, they have a U
shaped area where the wire goes and strictly speaking need a
different type of crimp tool which bends the tops of the U over
onto the wire, forming a sort of inverted W at the top onto the wire.

The terminals are

Yes Rod and these do it. If you look at a set you will see they
have a "U" shaped bottom groove and
a ... well pair of boobs shaped top groove that fold the Utilux
bits over and into the insulated wire.+

 

[ZAussieblue]

PS It fact Rod they don't work too good with the round terminals
just the open top utilux type.

 

[ZAussieblue]

PPS And in anticipation of Rod's usual sceptical response; If
you like I can dig out my set, some utilux 'phone terminals and
my macro lens and take a series of pics showing them in action.
Just tell me where to post the pics.

Those are fine for stripped conductors but the H1130
http://www.tycoelectronics.com.au/__data/page/1005/01130.pdf is
preferred for insulation piercing as is usually found on Telstra
supplied cords with 605 plugs.
