Crimp

[empip]

Exploring the ratchet crimper.

Tried some pictures.
I am sure the crimp deformation will be different with an inserted wire providing resistence...

A...

The crimped tube in A, above, was deformed with the larger arc jaw profile in B as shown.

B...

The tube in B has been deformed using the jaw profile in A. In this case the tube has been shaped into a smooth oval section without the split edges overlapping...

A couple of Q's.

If the distinctly differing jaw profiles, twixt one side of the tool and the other are the norm, which jaw should be crimping the inner metal tube?

Can someone explain the correct method and if there is a trick to positioning the tube split seam to best benefit the crimp?

Hi.

The correct use of this tool is as in picture A.

You will see that the insulated part of the crimp is deformed in a diamond shape. This is what Ampliversal call PIDG or pre insulated diamond grip.

This is designed to grip the insulation to prevent flexing of the cable strands and failure of the cable as it enters the crimp.

The jaw shown in picture B is to crimp the metal insert onto the cable strands.

Bit nerdy I know but I used to teach this stuff.

Searched the net pretty hard but that info was not easily found.

Can see the 'diamond' shape gripping the insulation in davelx's pix ...

Cheers folks.

Just download the pdf file from Tyco.

Have you seen the price of tyco's PIDG tools, worked with them every day for 5 years, last for ever but still no excuse for the price.Mainly used in the aircraft industry which is why they get away with the price.

Tyco also being rayfast and raychem.

Terminals for them generally made by AMP.
