Definitions

  • the invention relates to a terminal with an insulating housing, in which a busbar and at least one clamping spring is arranged, wherein a fixed end of the clamping spring on the busbar and a flexible end of the clamping spring elastically abuts against an abutment, and at least one conductor opening is provided in the insulating housing , through which a conductor between the abutment and the clamping spring can be plugged.
  • busbars which have terminals with bent portions for contacting conductors. These busbars are manufactured in several steps, which include a bending of these sections of the busbar, making the production of the busbar more expensive.
  • the object of the invention is to provide a busbar that is easier to manufacture.
  • This object is achieved in a generic terminal in that the abutment is plugged onto the busbar and the flexible end of the clamping spring presses a stop surface of the abutment against the busbar.
  • the clamping spring is advantageous for producing a contact pressure firmly against the abutment surface of the abutment.
  • the clamping spring is a leaf spring and has a U-shape.
  • the clamping spring is attached with its fixed end to the busbar.
  • the busbar is a flat stamped part and has a holding claw.
  • the abutment may have a plug-in opening for plugging onto the busbar and be produced as a stamped part, wherein the plug-in opening is advantageously formed slot-shaped for receiving the retaining claw of the busbar.
  • the abutment in a cross section perpendicular to the insertion direction of the conductor has a U-shape, wherein the busbar between the legs of the U-shaped abutment is arranged.
  • the legs of the U-shaped abutment taper conically.
  • a flange of the U-shaped abutment has an angled flange at a right angle, which is provided with a centering recess starting from the outside.
  • An abutment 9 in Figures 1 to 4, in the plan view of Figure 3 has a substantially U-shape with two legs 23 and a flange 25, wherein the legs 23 are conical to each other.
  • a plug-in opening 19 is provided, which extends in the view of Figure 2 slit-shaped from top to bottom. Inside, below the insertion opening 19, a stop surface 15W is provided, as shown in FIG.
  • the abutment 9 is punched out of a sheet metal strip so that it is formed as a one-piece stamped part.
  • Figures 9 and 10 show a bus bar 5 which is stamped as a flat punched part from a sheet metal strip.
  • the busbar 5 has at opposite ends in each case a retaining claw 17. Further, a stop surface 15 S is formed at opposite ends of the bus bar 5 respectively.
  • FIG. 11 shows an intermediate step during the attachment of the abutment 9 of FIGS. 1 to 4 to the busbar 5 of FIGS. 9 and 10.
  • the retaining claw 17 of the busbar 5 is inserted into the insertion opening 19 of the abutment 9, and the abutment 9 is subsequently pivoted about the retaining claw 17 along the pivoting direction S until the arrangement shown in FIG. 12 is reached, in which the abutment surface 15W of the abutment 9 on the stop surface 15 S of the bus bar 5 is applied.
  • a clamping spring 7 in the present case a substantially U-shaped leaf spring, is arranged between the abutment 9 and the busbar 5.
  • a fixed end 7S of the clamping spring 7 is arranged between a first contact surface 311 and an opposing second contact surface 312 of the busbar 5 in order to connect the clamping spring 7 to the busbar 5.
  • a flexible end 7f of the clamping spring 7 rests elastically against an upper end of the abutment 9 in FIG. 12, as a result of which the abutment surfaces 15W, 15S are pressed against one another about the retaining claw 17.
  • Figure 13 shows a view similar to Figure 12, but with a conductor 13 between the flexible end 7f of the clamping spring 7 and the abutment 9 is arranged.
  • a force exerted by the flexible end 7f of the clamping spring 7 on the abutment 9 force is transmitted through the conductor 13 to the abutment 9, so that the contact surfaces 15W, 15 S continues to be pivoted about the retaining claws 17 are pressed together.
  • Figure 14 shows a terminal 1 according to the invention with an insulating housing 3, in which the busbar 5 is arranged, wherein at opposite ends of the busbar 5 each have an abutment 9 and a clamping spring 7 are arranged.
  • the insulating housing 3 is injection molded from a plastic material and has two mating crosses 33, to which the busbar 5 is inserted by means of adapted plug-in openings 35 in order to fix the busbar 5 in the insulating housing 3.
  • the clamping springs 7 are each placed around a column-like protruding bending element 37, the lower end 37u can ablieen the busbar 5, to additionally fix the busbar 5 in the insulating housing 3.
  • An upper bending section 37oB of the bending element 37 is spaced from the insulating housing 3, whereby a clearance is formed between the bending element 37 and the insulating housing 3, through which the clamping spring 7 is pivoted downward in Figure 14, when a conductor 13 through a conductor opening 11 inserted along a plug-in direction 21 in the insulating housing 3 and between the flexible end 7f of the clamping spring 7 and the associated abutment 9 is arranged.
  • conductor 13 may be provided parallel to the conductor opening 11, an opening through which a screwdriver in the insulating 3 is plugged so that the flexible end 7f of the clamping spring 7 by the screwdriver is pivoted in the direction of the busbar 5, whereby the conductor 13 is no longer pressed by the clamping spring 7 against the abutment 9 and can be removed from the terminal 1.
  • an abutment 9 ' is shown, which is used as an alternative to the abutment 9 of Figures 1 to 4 in the terminal 1 according to the invention.
  • the abutment 9 ' is substantially identical to the abutment 9, so that following only a difference between the two abutments 9, 9' is described.
  • the abutment 9 instead of the legs 23, the abutment 9 'has a bent at a right angle relative to the flange 25 flange portion 27 in which a Zentrieraus Principleung 29 is formed from the outside.
  • the centering recess 29 surrounds a centering projection 39 which is formed on the busbar 5, in order in this way a lower end of the abutment 9' in FIG. to align with the busbar 5.
  • the busbar 5 of the terminal 1 according to the invention can be produced as a flat stamped part of a metal strip, so that the production of the busbar 5 is considerably simplified.
  • the abutments 9, 9 ' are held by the clamping spring 7 on the busbar 5, so that the abutment 9, 9' need not be connected via a welding, soldering or riveting with the busbar 5.
  • the abutment 9, 9 'of the busbar 5 are dissolved components, they can be plugged in different terminal types, on geometrically different busbars, or installed.
