Definitions

  • the present invention relates to a direct plug compression spring clip for conductor ends, in particular for stranded wire ends, according to the preamble of claim 1.
  • Direct plug compression spring terminals also called “push-in terminals” are known in various embodiments. They differ mainly due to their application, for example, depending on the required current carrying capacity of the busbar, the spring force of the clamping spring and / or their installation conditions, especially their size. Here are a simple installation and a cost-effective production permanently Asked for such a terminal.
  • the EP 1 353 407 B1 discloses in Fig. 28 a direct plug compression spring clip.
  • the DE 20 2008 014 469 A1 also discloses in Fig. 2 a generic direct plug compression spring clip.
  • Object of the present invention is to improve the generic direct plug compression spring clamp so that it is suitable for relatively rigid Vollieiter as well as flexible, especially fine stranded wire and this easily inserted into the Trimsteck-Druckfederklemme and safe in the Trimsteck-Druckfederklemme held and contacted.
  • the direct plug compression spring clamp of claim 1 is characterized in that on the busbar, a second contact zone is provided, which is also provided for guiding the electrical conductor end, and which is spaced from the first contact zone. Through the second contact zone, both the strands of a particular fine stranded conductor end and the conductor of a Vollieiterendes are guided during insertion. Furthermore, the direct plug-type pressure spring terminal is characterized in that the second contact zone is arranged in a conductor insertion direction behind the first contact zone. In addition, the second contact zone is formed by a cutout or a recess in the busbar. The cutout or the recess is provided in a circular or part-circular manner.
  • the electrical conductor in particular the strands of a stranded wire end, centered.
  • the strands are bundled thereby.
  • the distance between the first contact zone and the second contact zone is at least 2 - 5 mm.
  • the busbar preferably extends parallel to a plane spanned by a transverse direction transverse to a base plate of the clamping cage and the conductor insertion direction.
  • the base plate preferably extends parallel to a plane spanned by an extension direction of the direct plug compression spring clamp and the conductor insertion direction.
  • the bus bar has a third contact zone between the first contact zone and the second contact zone.
  • the third contact zone is preferably spaced from the first and / or second contact zone in the extension direction.
  • an electrical conductor inserted into the direct plug compression spring clamp is also pressed onto the bus bar by means of the clamping spring. With a sufficiently great flexibility, however, it is pressed onto the third contact zone. A sufficiently flexible electrical conductor therefore contacts at least the third contact zone and the second contact zone.
  • the section opposite the recess is preferred because it allows a greater variability with respect to the conductor cross-section.
  • the insertion of the conductor end is easier in a partially open cutout, as in a circumferentially closed recess.
  • the second contact zone is formed by a ramp which guides the electrical conductor during insertion into the direct plug compression spring clip.
  • the ramp preferably extends at a shallow angle to the conductor insertion direction.
  • the cutout or the recess is provided on such a ramp.
  • the first contact zone is formed by an edge and a line. It is particularly preferred that it has a sharp-edged design. Sharp-edged in the sense of the invention is an edge with a small radius, which is as far as possible not rounded beyond the producible dimension. Although such an edge is suitable for deforming a flexible electrical conductor end, in particular for deforming the strands of a fine stranded conductor end. It cuts and does not damage them. In principle, however, a contact surface is also suitable as the first contact zone.
  • the first contact zone is preferably arranged at a first end of the busbar and the second contact zone at a second end of the busbar opposite the first end.
  • the first and / or second contact zone may also be spaced from the first and / or second end of the busbar.
  • the first and / or second end of the busbar preferably in the region of the first contact zone and / or the second contact zone, or the first contact zone and / or the second contact zone is provided in each case a kink in the busbar.
  • the first contact zone and / or the second contact zone are provided by deformations of the or projections on the busbar. Such a deformation or molding is formed, for example, by a, in particular ramp-shaped, web.
  • the third contact zone has a contour or a coating which increases the roughness of the contact zone.
  • a contour can be formed, for example, by grooves.
  • another contour or a smooth third contact zone is preferred.
  • a clearance for the clamping spring is provided between the first contact zone and the second contact zone.
  • the franking allows a pivoting of a clamping leg of the clamping spring.
  • a spring stop for the clamping spring is provided between the first contact zone and the second contact zone.
  • the first contact zone forms the spring stop.
  • the clamping cage and the busbar are made in one piece.
  • the clamping cage is made with the busbar from a sheet as a punched and bent part.
  • the clamping cage is made with the busbar of a highly electrically conductive material, in particular of a copper-containing metal. Such production is cost-effective with respect to the production by conventional methods.
  • a stop extending transversely to the base plate is provided on the base plate for the clamping spring. Between the stop and the busbar As a result, a receiving space for the clamping spring and the electrical conductor is formed.
  • the clamping spring preferably has a holding leg and a clamping leg and a crosspiece connecting the legs to one another. It is preferred that the retaining leg extends approximately in the conductor insertion direction and is supported in a mounted state of the direct plug compression spring clip on the stop.

  • the crosspiece is preferably rounded.
  • the clamping leg is pivoted when inserting the electrical conductor end about a spring axis against its restoring force in a pivoting direction to the holding leg.
  • the retaining leg is supported on the stop.

  • the crossbar 30 is rounded here.
  • the invention is not limited to this embodiment. But it is also conceivable that between the legs 31, 32, a straight cross bar 30 is provided. In addition, an embodiment is conceivable in which the clamping spring 3 has no transverse web 30, but the legs 31, 32 are directly connected to each other.
