Definitions

  • the invention relates to a connecting terminal according to the preamble of claim 1.
  • a terminal of this type is known from DE 39 22 072 A1.
  • the plug contact consists of a socket designed as a blind hole of the clamping body, into which the contact blades are inserted.
  • the blind hole-like socket complicates the shape of the clamp body for manufacture.
  • the insertion of the contact blades means a separate assembly step.
  • the invention has for its object to provide a terminal of the type mentioned so that the manufacture and assembly are further simplified and thus cheaper.
  • the conductor protection elements of the screw terminal are manufactured and assembled in one piece with the contact lamellae of the plug contacts.
  • the conductor protection elements and the contact lamellae are punched out of a sheet metal stamping strip in a single punching process and can be assembled in one piece. This reduces both the manufacturing and assembly costs. Since the contact blades are connected in one piece to the conductor protection element, the electrically conductive contact between a wire conductor clamped in the conductor receptacle of the clamping body and a plug pin inserted into the plug contact is ensured.
  • An electrically conductive connection of the contact lamellae with the clamping body is not important, so that the contact lamellae can be inserted into a socket of the plastic terminal housing, which allows a simpler design and a lower material requirement of the clamping body.
  • connection terminal is made multi-pole with several clamping bodies in a terminal housing. This results in an additional simplification of manufacture and assembly.
  • the conductor protection elements with the contact lamellae of all the poles of the connecting terminal are punched out of the stamped strip, the sheet-metal stamped parts of the individual poles still being connected via a longitudinal strip of the stamped strip which attaches to one of the contact lamellae.
  • the free legs of the conductor protection elements are then bent in a U-shape and the clamping bodies are pushed onto the bent legs.
  • the connecting longitudinal strips separated and the contact blades bent, whereupon the clamping body with the stamped sheet metal parts are inserted into the terminal housing.
  • the axis of the plug contact runs perpendicular to the axis of the conductor receptacle behind the end face of the clamping body opposite the conductor receptacle.
  • the edge of the rear end face of the clamping body is expediently designed as a bending edge, via which the contact lamellae are bent off by the conductor protection element.
  • the rear end face is expediently beveled in such a way that the contact lamellae can be bent over an angle of more than 90 ° over this bending edge. Due to the residual elasticity remaining during the bending, the contact lamellae then take up the desired bending angle of 90 ° without tension after the release.
  • connection terminal is designed as a five-pole connection terminal.
  • a plastic clamp housing 10 In a plastic clamp housing 10, five cutouts are arranged side by side in the front, in each of which a metallic clamp body 12, preferably produced by the die casting process, is inserted.
  • the clamping bodies 12 have a conductor receptacle 14 at the end, which is designed as a blind hole. Perpendicular to the axis of the conductor receptacle 14 leads from the top through the clamping body 12 into the conductor receptacle 14, a threaded hole into which a cylindrical clamping screw 16 can be screwed, which is held captively in the terminal housing 10.
  • bushes 18 are arranged in the terminal housing 10, each perpendicular to the axis of the conductor receptacle 14, which run behind the rear end face of the inserted clamping bodies 12 facing away from the conductor receptacle 14 in the terminal housing 10.
  • a sheet metal stamped part is assigned to each clamping body 12, as shown in FIGS. 5 and 6.
  • the sheet metal stampings have a strip-shaped elongated conductor protection element 20, which has a circular opening 22 for the clamping screw 16 and the free leg 24 is bent in a U-shape.
  • the free leg 24 engages in the end of the conductor receptacle 14, while the conductor protection element 20 rests with its opening 22 on top of the clamping body 12 in such a way that the opening 22 coincides with the threaded bore of the clamping body 12.
  • the sheet metal stamped part Adjoining the conductor protection element 20 in one piece, the sheet metal stamped part has three contact blades 26, 28.
  • the contact blades 26, 28 are arranged parallel to one another, the two outer contact blades 28 each being connected to the central contact blade 26 via a crosspiece 30.
  • the middle contact lamella 26 is integrally connected to the conductor protection element 20 as an aligned continuation.
  • the middle contact lamella 26 is bent at right angles to the conductor protection element 20.
  • the transverse webs 30 of the two lateral contact lamellae 28 are bent against the central contact lamella 26 such that the three contact lamellae 26 and 28 essentially enclose a receiving cross section in the form of an equilateral triangle, as can best be seen in FIG.
  • the contact lamellae 26, 28 are located in the socket 18, their triangular receiving cross section being aligned coaxially with the bore 18. If a plug pin 32 is inserted into the socket 18, it is therefore pushed into the receiving cross section of the contact lamellae 26, 28, as shown in dash-dot lines in FIG. 5, the elastic spring force of the crossbars 30 being the contact pressure between the contact lamellae 26, 28 and the plug pin 32 generated.
  • the sheet metal stamped parts of all poles one The terminal is punched out, the stamped sheet metal parts of the individual poles still being connected to one another via a longitudinal strip 34 which attaches to the central contact lamella 26, as shown in FIG.
  • the sheet metal stampings connected via the longitudinal strips 34 are placed in an automatic machine in which the free legs 24 of the conductor protection elements 20 are first bent along the edges 36 shown in broken lines in FIG. The clamping bodies 12 are then pushed onto these free legs 24.
  • the lateral contact lamella 28 are bent around the edges 38 against the middle contact lamella 26.
  • the middle contact lamellae 26 are bent downward around the edge 40 relative to the conductor protection element 20.
  • the upper edge of the rear end face 42 of the clamping body 12 serves as a bending edge for bending the middle contact lamella 26 around the edge 40.
  • the rear end face 42 of the clamping body 12 is chamfered by an angle of 10 ° relative to the plane perpendicular to the axis of the conductor receptacle 14, as shown in FIG. 4. This makes it possible to bend the middle contact lamellae 26 around the rear upper edge of the clamping body 12 over an angle of more than 90 °.
  • the bending tool releases the contact lamellae 26 after the bending process, these loosen again due to their residual elasticity from the rear end face 42 of the clamping bodies 12 and assume a position perpendicular to the conductor protection element 20 (then without tension), as can be seen in FIG. 2 .
  • the clamping bodies 12 are held on the free legs 24 of the conductor protection elements 20 and the clamping bodies 12 with the stamped sheet metal parts can be inserted into the terminal housing 10 along the punching line 44 after the longitudinal strip 34 has been severed.
