Definitions

  • the invention relates to an electrical connection terminal, in particular terminal with a made of a flat material busbar having at least two plug connections for releasably plugging each one unsprung in itself, stiff plug contact a jumper, the busbars adjacent to each other terminals electrically connected to each other connects, wherein the plug-in terminals are designed in the form of resilient sockets in such a way that the leg ends of a manufactured as a separate component, U-shaped leaf spring cooperate with their respective outward spring force with the inwardly directed contact bearing surfaces of the busbar.
  • Terminals of this type are from the FR 2 803 441 B1 known.
  • the inwardly directed contact surfaces of the busbar are formed by superscript, ie bent out of the surface extension of the busbar busbar ends, which extend opposite to the insertion of the jumper plug contacts, whereas the clamping leg ends of the U-shaped leaf spring in the insertion direction of the plug contacts of the jumper all the way to extend the raised busbar end pieces of the bus bar, so that the inserted bridge plug contacts between the clamping leg ends of the leaf spring and the superscript busbar end pieces are clamped.
  • the object of the invention is to develop small-sized plug-in connections for the insertion of the jumper plug contacts, which reduce the overall height of the terminals of the type mentioned above total.
  • This object is achieved in that the formation of the plug-in connections in the busbar square through-holes are present, in which dive the leg ends of the leaf spring, and that the leg ends of the leaf spring are inserted from the bottom of the bus bar in the square through-openings such that the Leg ends opposite to the insertion direction of the plug contacts of the cross jumper extend.
  • the solution according to the invention has two significant advantages. On the one hand, it shows that the clamping regions of the spring-loaded plug-in connections can be moved into the plane of the surface extension of the busbar, whereby the overall height of the terminal can be reduced.
  • the teaching of the invention also shows that the arrangement of the U-shaped leaf spring below the busbar is very compact and also the pluggability of the jumpers is improved, since now the terminal areas of the plug-in connections when plugging in the jumper plug contacts are leading, ie are positioned right at the beginning of the plug-in operation, and the jumper plug contacts during insertion no longer have to be pushed past the possibly longer clamping legs of the U-shaped leaf spring.
  • a preferred embodiment of the invention provides that the square shape of the push-through openings has lateral stops which limit the outwardly directed maximum travel of the leg ends of the leaf spring, and that the free passage in spring travel direction between the lateral limit stops is equal to or greater than the transverse to Federwegraum measured width of the jumper plug contacts whose depth measured in spring travel direction is greater than the distance of the lateral limit stops of the inwardly directed contact bearing surface of the busbar.
  • the above features according to the invention improve the self-clamping effect of the U-shaped leaf spring in the through-openings of the bus bar.
  • the clamping leg ends of the leaf spring can be installed (inserted) with a higher bias in the through-openings of the busbar, since they can be supported with their spring force on the lateral limit stops in the insertion openings.
  • the installation is thus "self-supporting", ie the leaf spring carries itself and transmits no clamping force on the Isolierstoffgeophuse, and not even if only one plug connection of the two operated by the same U-shaped leaf spring plug connections is occupied.
  • the material thickness of the aforementioned hole collar also helps to improve the power line cross-section of the busbar in its longitudinal direction, as is particularly desirable in electrical feedthrough terminals.
  • Fig. 1 is a detail of a terminal 1 in the region of their Brücker-Einsteckitchte 2 and shown with an insulating material 3.
  • a busbar is installed in the terminal .
  • a U-shaped leaf spring 5 is positioned over fixing aids 6 and 7 of the insulating housing 3. With two leg ends 5.1, the leaf spring 5 clamps in the square material passage 8.
  • the material passage 8 narrows adjacent to the clamping leg ends 5.1 to a smaller passage area 8.1, which is smaller in cross-section and which serves to receive the plug contact 9 of the transverse bridge 9.1.
  • the bridge plug contact 9 protrudes with the Leg end 5.1 facing longitudinal side in the region of the material passage 8 inside.
  • the bridge plug contact 9 When plugging the jumper 9.1 in the bridge shaft 2, the bridge plug contact 9 pushes with its tapered tip between the leg end 5.1 of the leaf spring 5 on the one hand and the chamfered edge regions of the reduced passage region 8.1 on the other. In this case, the bridge plug contact 9 lifts the leg 5.1 of the leaf spring 5 by overcoming its bias from the lateral limit stops 10 in the material passage 8 and thus pushes between the clamping leg end 5.1 and the busbar 4, wherein the reduced passage area 8.1 contact the busbar 4 ensures.
  • plug-in terminal integrated into an electrical terminal in the form according to the invention of a spring-loaded socket is not only suitable for plugging in the plug contacts of a jumper, but can also serve to plug test plugs or other pluggable connection parts as well as pluggable solid conductors or electrically connect to the busbar of the terminal.
