Title: David Keller - Innovator in Crimping Technology
Introduction
David Keller is a notable inventor based in Lemgo, Germany. He has made significant contributions to the field of crimping technology, holding a total of 3 patents. His innovative designs have improved the efficiency and effectiveness of crimping tools used in electrical applications.
Latest Patents
One of his latest inventions is the self-adjusting crimping tool. This tool features a crimping arrangement with movable and fixed levers that pivot from an open condition to a fully closed condition. This design generates a first crimping force for crimping an electrical contact onto a bare conductor. When the levers reach an intermediate position, a predetermined compensating energy from a caged spring assembly is released to complete the crimping process. The spring assembly can consist of a stack of spring washers, a helical spring arrangement, or a stack of resilient elastomeric blocks.
Another significant patent is the crimping apparatus for turned contacts. This tool is designed to crimp the tubular portion of a turned electrical contact concentrically around the bare end of an electrical conductor. It includes a tool body with a main first portion and an integral coplanar second portion that defines a first lever. The crimping die arrangement features an annular stamp holder mounted opposite an opening in the tool body, allowing for precise crimping through a toggle link arrangement.
