Crimping Metri-Pack Terminals with an Open Barrel Crimp Tool

Crimping Metri-Pack Terminals is a little different than the standard Crimp tool that simultaniously does the conductor and insulation at once.

Metri-Pack Terminals can be purchased here, I recommend picking up extra to practice with http://www.cycleterminal.com/fuse-boxes.html

With this tool it will be a two step procedure, The conductor, then the wire seal.

There are a lot of different types of tooling out there, keep that in mind.


A decent selection can be purchased here http://www.cycleterminal.com/crimp-tools.html at very good pricing.

 First - Before striping the wire, Insert the wire through the seal.

Then you can strip the wire carefully so you don't nick or cut any of the stranded wires.

Next - You will place the terminal in the Crimp tool die.

Place the terminal in the die, so the wings for the conductor crimp are positioned toward the wire seal just off the die about .5mm.

(As seen in this photo)

This will give you a bell mouth, so the tool or crimped terminal does not cut into the wire stranding.

Make sure the wire stranding from your striped wire is straight, not spread out/apart, and not twisted. Insert your striped wire into the terminal, making sure all the strands make it into the terminal to be crimped.

(I normally slide the seal just up to the bare wire before inserting the wire into the terminal) I did it like this for the photo’s.

You can now crimp the terminal, and then slide the seal into place.

You should have something like this on the left.

And Finally the wire seal - (which serves as insulation stain relief, and to seal out the elements on this the sealed connector system)

This will only get a partial crimp, with the largest die on this tool.



You want just enough of a crimp to hold the seal in place, You don’t want to cut into it.

So stop applying pressure when you get to this point,

as seen in the photo on the right.


Release the ratchet using the lever at the bottom of the tool frame, you should now have a crimped terminal that looks like the photo on the right.

Good luck, you can do it too!!

Metri-pack Crimp tool and Standard Spade Terminal

Basically the same as above.

This will be a 2 step crimp as well, the Conductor, then the insulator.

Using a standard 250 14-18 AWG terminal and 16 Gauge wire.

Even though this tool is not designed for these terminals you can get some really good crimps with it.

(Provided you use the proper terminal, Wire Size, and tool die)

On the left is a photo of the back side of the terminal, showing the pressure the die put on the terminal.

And this one looks pretty good.

Now you can crimp the insulation with one of the larger dies.

(You may not want a complete crimp here as you do not want to pierce the insulation with the crimp)

And this should be your results when finished.

Good luck!!

        

  I hope to get some photo’s of the smaller pin terminals soon!!

Using an Open Barrel Crimp Tool

Hopefully this will help some of you with the use of your Crimp tools.
I tried to be as thourough as posible, Hope you can use this to your advantage.

Most of these tools can be purchased at www.cycleterminal.com
Crimp tool, wire stripers, terminal extraction
You will also find good selection of spade, pin, bullet, flag, and deutsch terminals here http://www.cycleterminal.com/spade-terminals.html



Standard Open Barrel Crimp Tool

First - Strip you wire to the proper length needed, This may be different for each type of terminal crimped.

This one approximately 5 to 6 mm will need to be striped.

Do not to nick any wire strands like I did in this second picture.

If you do cut the wiring down to the damaged standing, and re-strip the wire.

 Next - You will place the terminal in the Crimp tool die. In the photo on the left you are looking at the upper die, the left side of  the die in the photo is the wire/conductor crimp. Right side of the die will be the insulation crimp.

Place the terminal in the die, so the wings for the conductor crimp are off set slightly center into the gap between the dies surfaces.

This will give you a needed bell mouth.

So neither the tool die, or terminal cuts into the wire stranding.

And Finally - Making sure the wire stranding from your striped wire is straight, not spread out/apart, and not twisted. Insert your striped wire into the terminal, making sure all the strands make it into the terminal to be crimped.

(With some terminals, the wire will only go in so far before the insulation bottoms out in the terminal) otherwise if striped to the proper length, make sure you have about 1mm of wire sticking out the opposite side.

You can now crimp the terminal, and should have something like this on the left.

With a little practice you should not have a problem, Good luck!!
