Patent number: 8974243Abstract: A cable for the transmission of signals, includes a plurality of leads, on whose inner conductors an electrically conductive end piece is affixed. At least one of the end pieces includes a first latching element. The cable includes a coupler element, and the coupler element has a body having a longitudinal axis. In addition, the body has parallel feed-throughs, electrically insulated from each other, to accommodate the end pieces. At least one of the feed-throughs includes a second latching element. The end piece is inserted into the feed-through such that the first latching element locks into place with the second latching element. The body furthermore has a first surface and a second surface to guide a mating piece of the coupler element, the first surface having a radially outwardly directed normal vector, and the second surface having a radially inwardly directed normal vector.Type: GrantFiled: February 12, 2013Date of Patent: March 10, 2015Assignee: MD Elektronik GmbHInventors: Norbert Friese, Martin Huber

Publication number: 20070049112Abstract: In a method for producing a concentric coaxial cable and a corresponding coaxial cable, the coaxial cable includes a core, a dielectric enclosing the core, an electroconducting shield enclosing the dielectric, a jacket enclosing the shield, and a connector. The connector includes a contact sleeve which is contacted in a section with the shield in an electroconducting manner. The contact sleeve is located to enclose in the section the dielectric while being enclosed by the shield. The contact sleeve is mechanically linked with the jacket of the coaxial cable by an extrusion coating so that the extrusion coating serves to relieve the strain on the contact area of the subsection with the shield.Type: ApplicationFiled: September 3, 2004Publication date: March 1, 2007Inventors: Norbert Friese, Rolf Goenner
