Definitions

  • the invention relates to an electrical connection terminal for a screw connection with a passage for a tensioning element base plate, on which angled anchoring legs, which are bent at right angles and parallel to one another, for receiving a spring clamp washer, and with contact webs standing upright on opposite sides of the base plate.
  • An electrical terminal of this type is known from DE-U-1 947 175. This terminal is designed for mounting on rails. This terminal is not suitable for mounting on connecting pins.
  • the object of the invention is to provide a screw terminal which can be easily attached to pins in housings, in particular connection housings.
  • each anchoring leg ends in two tongues, each having mutually opposed slots, that the spring washer is inserted into these slots and that the front side wall of each slot is pressed against the spring washer.
  • the invention differs from the prior art in that the anchoring legs holding the spring clamping disk enclose sufficient space for receiving the pin and for accommodating the shaft of the tensioning element for the conductor wire.
  • the screw terminal consists of a narrow sheet metal blank of uniform width, so that the manufacturing and material costs can be kept low.
  • the spring washer is in the Slits are captively clamped and held when they are pressed on, so that perfect assembly is guaranteed.
  • the material requirement is kept particularly small in that the passage is designed as a threaded passage, that the anchoring legs each have a free cut in connection with the base plate and that the cut-out tab is bent as a contact web.
  • the space required for the connecting terminal can be kept small by the fact that the anchoring leg itself serves as a contact leg and that a screw reaching through the passage carries a nut. The conductor wires are then clamped to the anchoring legs.
  • the flat sheet metal blank has a drawn, sleeve-shaped passage 2 with a thread 3 in a base plate 1.
  • Anchoring legs 4 adjoin the base plate 1, each of which has a window-like free cut 5, the cut and bent tab serving as a contact web 6 of the finished connecting terminal.
  • the ends of the anchoring legs 4 run into mutually opposing tongues 7, each of which have mutually aligned, opposing slots 8.
  • the front side wall 9 of each slot is comparatively narrow.
  • the width of the sheet metal blank is essentially constant everywhere and corresponds to the width of the anchoring legs.
  • the anchoring legs 4 are bent at right angles to the base plate 1 at the fold lines 10.
  • the contact webs are also bent at right angles on the fold lines 11. however in the opposite direction to the anchoring legs 4, so that the anchoring legs 4 and the contact webs 6 are aligned essentially parallel to one another at the connecting terminal, as can be seen in particular from FIG. 3.
  • the slots 8 receive a spring washer 12 which is cut out of a spring band and shaped.
  • This spring washer 12 can be automatically inserted into the slots 8 in the manufacture of the terminal.
  • the side walls 9 are pressed in the direction of arrow 13, so that the spring washer 12 is firmly clamped in the slots 8.
  • the narrow side walls can be easily deformed.
  • the terminal is pressed according to Fig. 3 with the spring washer 12 on a pin 15 or another approach of a housing or a support plate 16 and fastened in this way.
  • the spring washer 12 acts in a known manner.
  • the anchoring legs 4 have a sufficient length so that on the one hand the pin 15 and on the other hand the foot of a connecting screw 14 to be screwed into the thread 3 can be accommodated without any obstructions.
  • the connecting screw 14 is screwed into the thread 3 and clamps conductor wires 17 in the usual way. The position of the conductor wires is fixed by the contact webs 6 so that the conductor wires cannot step under the head of the connecting screw 14.
  • Fig. 5 shows a modified embodiment.
  • the shaft of the connecting screw 14 extends through the thread-free passage 2.
  • On the thread of the connecting screw 14 sits a square nut 21, which is guided between the anchoring legs 4 'without rotation.
  • the conductor wires 17 are clamped in a known manner.
