Abstract: A carrying device for busbars, having at least one holding device to be fixed on a base unit. The device has a receiving opening for feeding through at least one busbar, and a clamping device for fixing the same. Expanded installation possibilities of busbars result if there is a receiving part that is inserted, or that can be inserted, in the receiving opening. The part can have at least one recess that is adjusted to the cross-section of a busbar, and the respective busbar can be selectively disposed in the holding device in at least two installation positions pivoted about the longitudinal axes thereof, by the receiving part.

Abstract: An apparatus for mounting bus bars having at least one bus bar holder which can be attached to a loadbearing structure and which has at least one foot receptacle for introducing a foot section of a bus bar and fixing the latter by a holding piece. Simple, stable mounting of bus bars can be achieved if the holding piece is configured as a separate part which can be attached releasably or which is attached releasably to a base part of the bus bar holder and which has a connecting section for attachment to an adapted holding piece receptacle of the base part and a head part which engages over the former for fixing the foot section.

Abstract: A bus bar system with an assembly unit having a base plate with side limbs and fixing items which are connected to the assembly unit. The assembly unit forms a receiving element for a bus bar holder and bus bars which are covered with cover elements and/or adapters for peripheral devices. The covers and/or adapters are mechanically connected to the bus bars by plug-in receiving elements and/or locking receiving elements and the adapters are also electrically connected to the bus bars. An assembly unit, which can be produced and mounted at low cost without impeding functional requirements, is provided and the assembly unit forms locking receiving elements together with retaining flanges, which protrude at a distance on the outer sides of the side limbs, and fixing flanges, wherein bar-shaped fixing items can be inserted into and/or locked inside the receiving elements.

Abstract: A connection or device adapter, which can be placed on a mounting unit at right angles with respect to a longitudinal direction of busbars and mechanically connected, one contact element being electrically conductively connected to the facing busbar in a connection or device adapter per busbar and the contact elements in the connection or device adapter being led up to connection receptacles in the region of a narrow side of the connection or device adapter. If the contact elements are formed as contact bars and are electrically conductively connected to one another by the associated connection receptacles and form connection units and for the connection or device adapter to have receptacles for the connection units in the region of a narrow side and to accommodate the contact elements with contact points positioned in relation to the busbars, the complexity in terms of parts and assembly, in particular for the connection or device adapter, is substantially reduced and simplified.

Abstract: A device adapter including a base part, the bottom side of which has busbar fixtures to be mounted on and contacted with busbars while the top side thereof supports a mounting device that is removably fixed and has two parallel spaced-apart longitudinal rails for coupling electric devices or house wiring units. In order to keep the design simple while offering variable mounting possibilities, the connecting device includes protruding, hook-type hanging elements which are molded onto the bottom side of the longitudinal rails, which can be vertically inserted into receiving holes that are adjusted thereto and are located on the top side of the base part, and which can be hung on the side of the receiving holes facing away from the top side in the area behind the receiving holes by performing a movement in the longitudinal direction. A releasable locking element can lock the hung position of the longitudinal rails.

Abstract: A device or connection adapter having a base part, in which contact-making units with connection contacts are accommodated for making electrical contact with busbars of a busbar system, and having a holding apparatus for detachably fixing the device adapter with respect to the busbar system. Given a simple design and simple operation, variable coupling options are provided if the holding apparatus has different, modular connections and clamping feet, at least some of which can be fitted detachably to the base part, in order to mechanically fix the device adapter either to a supporting apparatus of the busbar system or directly to at least one busbar.
