Abstract: An electrical cable is disclosed, for example, a flat electrical cable in which a marker on one side of the cable or in which a marker of a subsequent orientation of the cable may be formed without additional costs. The electrical cable has an orientation marker which has at least one recess in the electrical cable and which is provided in the electrical cable so as to facilitate correct alignment of the electrical cable during installation and/or manufacture of the electrical cable.

Abstract: A rotary loop back connector comprises a rotor and a stator defining a cable holding space therebetween, the rotor and stator having portions relatively movable with respect to each other. In a preferred application, the rotary connector is used to establish electrical connections through the steering unit of an automobile. The stator is fixed to the steering column and remains stationary therewith while the rotor rotates with the turning of the steering wheel. The rotary connector includes a cable holder accommodated in the stator within the holding space, the cable holder being rotatable with respect to both the stator and rotor. A flat cable is supported by the cable holder, the cable having a first end fixed to the stator and a second end fixed to the rotor.

Abstract: An arrangement is provided for electrically connecting a rotatable current contact to a stationary voltage, such as used in the connection of an airbag in an automobile steering wheel. The arrangement comprises an insulated electric line which extends between the current contact on one side and a voltage, current or signal source on the other side and which is coiled around a rotary shaft member. The electric line is in the form of a helical spring, the spring being disposed on an inner housing portion which is positioned on the rotary shaft member and is non-rotatably connected thereto. An outer stationary housing portion encloses the inner rotatable housing portion with the helical spring being situated between the two housing portions.

Abstract: An electrical connector for coupling a stationary connection to a connection which rotates therearound includes a housing and flat conductor cable. The housing includes a housing bottom and a housing cover. The flat conductor cable is wound into a spiral and is supported in the housing. The flat conductor cable further includes bent ends which extend from the spiral at 90.degree.. An outer protective sheathing covers the bent ends of the cable as well as a portion of the spiral.

Abstract: The invention concerns a filtered plug connector comprising a housing and plug pins which are held therein. The filtering of high-frequency signals to ground is achieved by multi-layer ceramic capacitors electrically connected between the plug pins and a ground plate. For mechanically fixing same, the capacitors are resiliently clamped between the plug pins and bent, resilient portions which project from the ground plate adjacent openings in the ground plate through which the pins pass.
