Мой вопрос: "I mean that external diameter of butt (solderless connector) can be different. Haupa butt have external diameter 7 mm, klauke - 6.7 mm.So, the question is - what is the max diameter that can be inserted in 10 mm2 hole of 97 52 13 crimping tool."
Их ответ: "Yes you are right. Depends from the butt connector, the manufacture or the DIN, you have different wall thicknesses.In case, when the wall thickness is too big, it could be that the pressure between the connector and the cable isn?t correct. Or it could be possible that the crimping die will be broken.To solve all these problems we have developed a new crimping die. It has another design an you can crimp all types off butt connectors. This crimping die is built in of the crimping tool 97 52 13. Attached you will find a PDF file. This file show the different between the standard crimping die and our new designed crimping die."
Вкратце: причина перехода на новую форму пресса - W-образный зуб вдавливает "лишний" материал внутрь гильзы, в результате он не выдавливается наружу ввиде "ушек".
