The second link says it is for heat shrink terminals but the picture is of a double crimper only for non heat shrink connectors. The other 2 links are for double crimpers not suitable for heat shrink terminals.

I'm sure the correct crimper, like in the pic I posted, is available in the UK but I cannot help from here.

What you need is the tool shown below or one like it. The one pictured is by Ancor - there must be a similar product in the UK

I know that's what I want, my question is where can I get one in the UK ?

Thanks for your reply,

Boo2

Before I did my research and settled on double crimp with heatshrink tubing I had a single crimp tool. I got it from one of the sheds as it was cheap. I occasionally see them in a packet with poor quality terminals when I am looking for other things. I would suggest trying B&Q, Homebase and Halfords as I am sure it was in one of these.

Or you could do what the rest of us do and give them a squeeze with snipe nosed pliers and solder the wire to the back,

I know you said you'd tried Farnells, but a v quick google did go straight to this. Any good?

I find the Farnell site almost impossible to use but try the Davico site directly, its a crimping revelation

Usually I find a phone call to a major supplier the best way of resolving a technical problem because they actually know what they are talking about.

Just to update on the Davico/Farnell crimp tool, I had a reply from Davico's CS to the effect that "Our DHCR-HS produces a double crimp".

Thanks for the suggestion anyway though,

HS crimps

I sympathise with you, chasing round in circles.

Looking at the link you gave, there is no mention of the manufacturer's name. Would it be worth while getting back to them and finding out and then take it from there?

Criming tool

Hi Boo2, hopefully you have, by now, overcome your problem.

If not, why not try a cheap crimping tool. When I was first introduced to them as an apprentice electrician many years ago, the crimping tool was only 2 - 3 mm wide so could only do a single crimp. There were the 3 sizes red, blue and yellow plus one for the insulation.

My guess is that the crimpers available from DIY stores would be of this type rather than the more expensive ratchet type.

Hope this helps,
Paul

And how many times have i seen crimps made with the inexpensive tools fail?

Failure

True, but Boo2 is trained and experienced in making crimped terminations - see his earlier post.

I understand now, Boo2 has calibrated fingers and can gauge the force without a ratchet assisting.

I understand now, Boo2 has calibrated fingers and can gauge the force without a ratchet assisting.

The photo of the ratchet crimping tool originally posted by Boo2 is not capable of being calibrated for the amount of force applied to the termination. The purpose of the ratchet is to provide mechanical advantage for the user. The crimp with the ratchet type is complete when dies are closed and ratchet allows the handles to be opened so allowing the dies to be pulled apart.

The cheap type which I mentioned earlier will crimp perfectly well if used properly. There are usually two flat surfaces on the handles which will meet only when the crimp is fully compressed. Failure to ensure these flat surfaces touch will indeed produce a bad crimp.

In the ratchet type tool, it is the tool itself which determines the degree of compression, while with the cheap type, it is the operator who must observe that the compression is complete.

As mentioned earlier, Boo2 has been trained in the use of crimps. I would therefore be confident that he could produce good terminations with some of the cheap crimping tools available.

How it should be done by youtube http://www.youtube.com/watch?v=x_ESKEBcPjY

Ftfy

That is exactly what should not be done because that crimp tool is designed for plastic insulated (automotive) crimps which are thicker than the heat shrink ones so that crimp will not be properly formed. Also, both crimps were placed in the butt terminal which means that one of them is completely the wrong size anyway, being designed for the insulation crimp in an automotive crimp, not the wire crimp in a heat shrink crimp.

It's interesting as well to note that the other half of the butt joint was not made, is this because there would be no room for 2 crimps in the other half of the butt ?

So FYI, that is exactly what not to do...

+1 it's almost like it is a spoof video

 

[Deleted member 36384]

Cant help you unfortunately Boo2 but this has thread has been quite educational for me. That last comment you made about the video and watching the video has made the various comments on this thread quite clear now.

Good luck in your search for the heat shrink crimp tool.

PRT5 Crimping Tool For Heat Shrink Terminals

From here http://www.kojaycat.com/Heat Shrink Terminals.htm

Really as has been said above the certain way to avoid damaging the plastic is to slide heat shrink tube, preferably the type with adhesive, over the wire after an uninsulated crimp. Anything other than a butt joint remains open to corrosion.

Nope. That is the identical double crimp tool to what all the adverse discussion in this thread has referred...

Whilst trying to educate myself, I came across this web site. To me (an amateur DIYer) it seems very good. Hopefully those in the know will confirm this.
