Optimum results with respect to a high
-quality and permanent electrical connection with
maximum conductor pull forces at the same time can be achieved by using crimping dies
,
preferably with smooth surfaces, which ar
e provided, for example, with rectangular and
-sections.
Crimping dies with a pronounced wave profile are unsuitable.
