Abstract
A contact element such as an end-sleeve or a cable shoe, having a connecting portion and a contact portion, is produced from an originally plane blank which has a substantially rectangular first part, which in the finished product defines said connecting portion, and a second part, which in the finished product defines said contact portion. A plurality of such blanks is joined into a metallic punching band with an obverse face and a reverse face and comprising a first zone with all the first parts of the blanks, and a second zone with all the second parts of blanks. On at least the obverse face of the first zone is an insulating cover or coating applied before the individual blanks are removed from the punching band, so that the contact elements having a metallic connection portion with an insulating layer are obtained.
