  • Patent number: 4728298
    Abstract: The contact member comprising knife-edge pinch contact is based on a sheet metal blank bent U-shaped wherein a wall containing the contacting slot is formed by a portion of one of the U-legs of the sheet metal blank which is angled off door-like into the region of the U-contour. Tabs are cut free from the limiting walls of the U-contour and are bent out such with their free ends that the free ends of the tabs press into the insulating layer of a conductor which is pressed into the contacting slot. Points provided at the free ends of the tabs thereby dig into the insulating layer of the conductor and thus, effect a mechanical relief of the actual knife-edge pinch contact location given a simple format of the contact member.
