Ratchet Crimp Pliers

[revilla]

I've got myself a pair of Ratchet Crimp Pliers and I'm mystified to find that the jaws have different profiles on either side, one side like this (circles with side bars like a London Underground sign) and the other side like this (pointy ellipse, the same kind of profile as on a cheap pair of Draper non-ratchet crimpers).

 

Please excuse the numpty question but what are the two sides used for and why are they different? When should I use one and when should I use the other?

 

Thanks.

The two sides are crimping different parts of the connector. On a coloured crimp connector, there is a thinner part which the bare wire goes into, and then a wider part that has the wire/insulation in.

*arrowup* *arrowup*Yes, pictures and description here explaining the crimp for the contact with the wire and the crimp for the strain relief.

Thank you kindly gentlemen! All makes sense now.
