Method for quality assurance of crimp connections produced by a crimping device and crimping tool and crimping device therefor

摘要

The method for quality assurance of crimping connections made by a crimping device having an exchangeable tool with two tool parts uses a tool that is provided with an electronic data storage device. The electronic data storage device stores tool-specific nominal data derived from a nominal force-stroke characteristic line of a nominal crimping action of the tool. A crimp connector is fastened to the end of an electrical cable by placing the end of the electrical cable and the crimp connector between the two tool parts and moving the two tool parts relative to one another for carrying out the crimping action. The force-stroke characteristic line of the two tool parts is measured during the crimping action. The measured force-stroke characteristic line is compared to the stored nominal data.
