Abstract
Abstract An electrical connector for a flat cable. The connector includes a plurality of contact elements and a body having chambers for receiving the contact elements. Each contact element has a contact part for contacting other connectors, a connecting part for coupling to the flat cable and a middle part connecting the contact part and the connecting part, the connecting part being formed by bending about an axis which is essentially parallel to a major axis of the contact part after the associated contact element is received in its associated contact chamber.
