Definitions

  • the present invention relates to a current-conducting hollow profile as defined in the preamble of independent claim 1.
  • conductors in the form of current-conducting hollow profiles are used, which comprise at least one continuous cavity.
  • the hollow profiles consist of copper or copper qualities with a high electrical conductivity.
  • a current-conducting hollow profile is known from US Pat. No. 3,987,238, the inner sides of which have furrows.
  • the hollow profile consists of four profile parts that are welded together.
  • the fact that the hollow profile consists of four individual parts that are connected to each other leads on the one hand to increased production effort and on the other hand to reduced strength and flexibility.
  • FR-A-2 401 712 describes a method for producing a two-channel tube which comprises two bent tube parts which are welded to one another and between which an intermediate wall is welded.
  • This two-channel too Pipe has the disadvantage that it consists of three individual parts that are welded together. In addition, the pipe and partition walls are very thin.
  • Hollow profile production methods are also known, in which two profile parts are produced, which are then assembled by the rotor builder. The two profile parts are held together relatively loosely, for example, by insulation wrapped around them or by a connecting element. Hollow profiles of this kind, which form the closest prior art, have the disadvantage, among other things, that they are unstable and can only be bent to a very limited extent.
  • the invention is based on the following object.
  • a current-conducting hollow profile of the type mentioned at the outset is to be created, which can be produced with less effort, at least in the same quality or with the same effort, in better quality, with rapid passage.

  • the current-conducting hollow profile according to the invention comprises two separate profile parts, it can be produced faster, more rationally and more cost-effectively with at least the same quality. It is not necessary to press bolts over brackets in the extrusion process, which often have to be replaced.
  • the profile parts can be manufactured continuously. The firm connection of the two profile parts on at least one web ensures on their side a significantly greater stability and a very good bendability in comparison with the previously known two-part hollow profiles. It is also calculable and therefore associated with fewer risks than connecting the upper and lower profile parts in the extrusion process.
  • the complex customer requirements require a solid, stable product.
  • the manufacturing tolerances (mechanical values, dimensions) and the surface quality can be improved with the hollow profile according to the invention.
  • the two profile parts are mechanically connected to one another. Better strength, stretchability and extensibility of the hollow profile can be achieved than when the profile parts are welded. In addition, there are no weld seams and there is no risk of oxidation of the cavity or cavities.

Abstract

L'invention concerne un profilé creux électro-conducteur composé de deux éléments (1, 2) qui délimitent deux cavités continues (3, 4). Ces deux éléments (1, 2) sont solidement assemblés de façon mécanique à trois segments (6, 7, 8). Chacun des deux éléments constitue respectivement une partie de chaque segment. Les parties segments de l'élément profilé (2) présentent à leur extrémité respectivement un prolongement en T qui est maintenu entre deux branches en L de la partie segment associée de l'élément profilé (1). Ainsi l'une des parties segment agrippe partiellement l'autre partie segment et les deux éléments profilés (1, 2) sont solidement assemblés avec un faible jeu.
