A: For belt-linked contacts there are generally two crimping procedures occurring at the same time - the so-called wire crimp (lead crimp) and the insulation crimp. Continuous evolution of the connection technology has also resulted in a variety of new crimp connections as with the 3-zone crimp for coaxial cables.
The wire crimp makes the mechanical-electrical connection between the stripped inner conductor (e.g. stranded wire conductor) and the contact, and it has to be connected gas-tight to it.
- The insulation crimp should intercept acting forces such as vibration or pulling, so that they do not act on the wire crimp and they represent a purely mechanical connection of the contact element to the cable insulation. It is important, that the insulation is not damaged by the insulation crimp.
