  • Patent number: 8974243
    Abstract: 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.

  • Patent number: 8348677
    Abstract: In a slip-ring unit for electrically connecting two components that are rotatable relative to each other, one component is arranged as a first cable, which has a core and a shield. The slip-ring unit includes first, second and third brush elements as well as first, second and third slip bodies. The first slip body has an opening extending through it axially, through which a first cable extends for transmitting the voltage applied on the core. The second brush element is additionally disposed at a radial offset with respect to the third brush element.

  • Patent number: 8202130
    Abstract: A data cable including an electrical line with a plurality of line leads, an electrical shield, a molded piece including first counterpart form-locking elements and a housing enclosing the molded piece, wherein the housing has a central opening. The data cable further including a plug connector disposed on an end of the data cable, wherein the plug connector is electrically connected to the shield, wherein the plug connector includes a bush that is enclosed by the molded piece. The bush includes a deep-drawn tube and a bead with second form-locking elements which with the counterpart form-locking elements form a first form-locking connection, wherein an outer contour of the molded piece and an inner contour of the central opening of the housing form a second form-locking connection.

  • Publication number: 20070049112
    Abstract: 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.
