Definitions

  • the present invention relates to a Mehrfachrometulpe for connecting an electrical conductor component with an electrical assembly.
  • contact elements having a plurality of contact surfaces to the conductor component.
  • the current transmitted from the conductor component to the electrical assembly is distributed to the plurality of contact surfaces and reduced correspondingly to each individual contact surface.
  • the publication DE 20 2011 110 604 U1 shows a spring pressure piece with two end portions, which are each formed as contact areas.
  • the contact areas are provided for installation on a busbar.
  • the spring pressure piece is made of a longitudinally extending rail which is looped so that there is an acute angle between the first end portion and a center connecting the end portions and an obtuse angle between the center piece and the second end portion.
  • the end portions are therefore arranged at the open ends of the spring pressure piece.
  • two such spring plungers are connected together with a contact element to a four-contact spring pressure piece.
  • the contact element is arranged on the middle piece of both spring pressure pieces and extends transversely to these.
  • the busbar with an electrical assembly is connectable.
  • a contact element is known.
  • This contact element comprises at least two contact rails extending in a longitudinal direction, which are arranged one above the other and spaced apart in a contact direction.
  • the contact rails are connected by a connector.
  • the contact element is characterized in that the connecting piece is arranged on a first side of the contact rails on this, and extends in the longitudinal direction and in the contact direction, so that the contact element in a cross-section transverse to the longitudinal direction, which extends through the connecting piece, about u- is formed shaped.
  • Object of the present invention is to provide a Mehrfachrometulpe with contact elements in which the current path small, and the contact pressure of the contact surfaces of an electrical conductor component by the other contact surface of the same contact element little affected, and in particular approximately the same, wherein the respective contact element In addition, it is inexpensive to produce.
  • the object is achieved with a Mehrfachrometulpe with at least two contact elements.
  • Each contact element is in turn provided for connecting an electrical conductor component to an electrical assembly.
  • the contact element comprises at least two contact rails extending in a longitudinal direction, which are arranged one above the other and spaced apart in a contact direction.
  • the contact rails are connected by a connector.
  • the contact element is characterized in that the connecting piece is arranged on a first side of the contact rails on this, and extends in the longitudinal direction and in the contact direction, so that the contact element in a cross-section transverse to the longitudinal direction, which extends through the connecting piece, about u- is formed shaped.
  • the contact rails are therefore not connected to each other along the longitudinal direction, but they each have two open ends.
  • the current path therefore does not flow through a loop-shaped center piece, but becomes laterally into the connecting piece directed. Due to the lateral arrangement of the connecting piece of the current path is shortened. A heat caused by the current can therefore be dissipated faster.
  • the Mehrfachrometulpe is also provided for abutment with opposite sides of the conductor member.
  • the contact elements are arranged mirror-symmetrically to a median plane. They are also arranged one above the other in the contact direction. As a result, the conductor component is jammed between the contact rails.

  • the connecting piece is preferably arranged in the connection region of the contact elements.
  • adjacent connecting pieces of the Mehrfachrometulpe are respectively arranged on opposite narrow sides of the same contact rail. This allows easy insertion of the conductor component between the contact elements. The conductor component is then inserted between the contact elements and into the connection area in the Mehrfachrometulpe.
  • the contact rails are not connected together along the longitudinal direction, their angles do not influence directly.
  • the contact force with which one of the two contact rails bears against the conductor component is therefore not or almost not influenced by the other contact rail.
  • the contact force of the contact rails is therefore essentially independently adjustable.
  • the contact rails, in particular their length, their shape and / or the material of which they are made, are preferably dimensioned such that the contact force of the contact rails of the contact element is approximately the same.
  • An electrical conductor component according to the invention is both an at least partially planar electrical conductor such as a busbar, as well as an electrically conductive contact surface, for example, on a printed circuit board.
  • the front contact rail in the contact direction extends in the longitudinal direction beyond the rear contact rail in the contact direction.
  • the contact rails can be arranged one above the other without touching each other.
  • the one extending in the longitudinal direction over the other contact rail addition contact rail is also referred to as a first contact rail, and the other contact rail as the second contact rail.

  • the contact rails are preferably flat with a broad side of the conductor component.
  • the broad side preferably extends in the longitudinal direction and a transverse direction which extends transversely to the longitudinal direction and transversely to the contact direction.
  • the contact rails preferably have two narrow sides, which are arranged opposite one another and adjacent to the broad side. The narrow sides preferably extend in the longitudinal direction and in the contact direction.

It is particularly preferably formed in one piece with these, preferably as a stamped and bent component made of a flat strip material. It is particularly preferred that the connecting piece extends just in the longitudinal direction and the contact direction.
  • the contact rails are preferably arranged parallel to one another in a connection region in which the connection piece is arranged on the contact rails.
  • a connecting angle between the contact rails and the connecting piece is therefore preferably in each case 90 °.

  • Each of the contact tongues preferably has a contact surface in each case.
  • the contact tongues preferably extend from the connection region to the first open end.
  • the contact rails in particular the contact tongues, are bent or bent in the contact direction. For this they preferably have an obtuse-angled kink.
  • the contact tongues are each formed arc-shaped on the contact surface, so that they have no sharp edges, and the conductor component is not damaged by the contact tongues.
  • the contact tongues preferably have an obtuse-angled arc.
  • the Mehrfach.tulpe is in a cross-section which extends transversely to the longitudinal direction, and which extends through the connecting piece, formed approximately w-shaped.

  • two contact rails are located on opposite sides of the conductor component to this. Preferably, they are arranged mirror-symmetrically to one another.
