Crimping connector block terminals

[alun111]

Hi,

I'm Just looking for a little help on something, if you don't mind.

How do you crimp the terminals in connecting blocks? I've been looking for a crimping tool to do them and I haven't had any luck.

All the tools out there seem to be made for insulated (red,yellow,blue) terminals and the non insulated ones (I'm assuming the same but without the plastic covers). Would these crimping tools for non insulated terminals work on the terminals inside these connecting blocks? As there isn't just a "barrel" that the wire is crimped inside, but rather it's an open barrel shape...

I usually use pliers for the insulated terminals but I've never crimped this style of terminal before so really don't know how to do it.

I've posted this thread on another forum and I'm looking for more opinions.

Inside a factory connector block the terminals are crimped like so:

Here is a picture of the terminals I am wanting to crimp:

As far as I know the crimp at the start of the connector (the one that grips the insulation of the wire) is just crimped by carefully bending the tabs with pliers - but correct me if I'm wrong. It's the crimp where the bare wire is gripped that I need to know how to do.

Thanks in advance for any help you can give!

In the past when I have used those types of connectors, I have always soldered the wire into the groove bit then folded the tabs over the insulated bit of wire to secure it.

That's how I have always done it anyway, I don't think you are supposed to crimp these types.

Hi. If you go to the vehicle wiring products website, you will find this:

which is what I bought to crimp the same terminals as you have. As you know, the first crimp is for the wire, and the second crimp is for the insulation.

As for soldering the joint, well, that is a better electrical connection, but can make the terminal joint quite brittle. I prefer to spray the connector block with something like ACF50 to coat the connectors.

A decent crimp-tool makes it a lot less hassle. Otherwise I tend to use pliers, which will work but take longer - should be ok if it's not quite as neat as the proper tool providing they're down quite tight. Cheap crimp tools you get with some kits seem to be pretty useless.
The ones listed in the post above seem to be a reasonable choice.
My old company were chucking out a load of such stuff so I grabbed the crimp tool and it certainly has enlightened my crimping experiences!

I always just use some long nosed pliers to fold over each tab one at a time. I press the big tabs at the back down over the covered wire, and the thin ones in the middle over the stripped end of the wire.

A decent crimp tool will do the work for you (you shouldn't have to bend anything), but as G stated, cheap crimping tools can be pretty useless.

The tool I linked to does the folding for you, and is a decent item. The jaws are formed with 'McDonalds arches', such that as they are closed down on the crimp tabs, the tabs are forced to curl over and down on the wires. There are two size formers, with the larger one designed to crimp over the thicker insulated part of the wire. The operation is thus a two-part process: wires first, insulation following. The result is pretty much like the 'real thing'.
