Definitions

  • the invention relates to a terminal block with a Isolierstoffgeophuse and a connection device for one insulated conductor without stripping between one Cutting edge and a counter support is clamped.
  • This connection technology simplifies and speeds up Work what with switchgear and machines in particular high wiring volume and meter-long terminal strips Beech beats.
  • Stripping-free terminals are known, for example according to FR-A-2 503 464, which is an essential connecting element Have cutting bushing or the like.
  • FR-A-2 503 464 which is an essential connecting element Have cutting bushing or the like.
  • the leader leads a movement perpendicular to its longitudinal extent.
  • the Insulating jacket is pulled from the cutting edges in one Cut penetrated until the copper core with the cutting edges comes into contact. If necessary, the cutting edges penetrate partly also in the copper material.
  • the width is in the baying direction economically important criterion.
  • the lower limit this width is the sum of the outside diameter of the insulated conductor and the thickness of the wall of the Isolierstoffgeophuses, the two terminal blocks from each other separates.
  • the thickness of the cutting sleeve of the known Stripping-free terminal necessarily exceeds that The diameter of the insulated conductor is considerable. You have to go from a slot width that is almost the same locally Conductor diameter is. Then there is the width of the two Cut and possibly their folded parts, so that overall there is a relatively wide terminal block.
  • German patent application DE 31 22 303 A1 a spring clip for connecting an insulated electrical Conductor disclosed on a terminal block.
  • the spring clip includes a fixed and a spring movable leg in the clamping device with in Cross-section wedge-shaped and notched in the center IDC edges, the end portions of the legs are arranged crossing each other at an acute angle.
  • the spring clip has a width that is clear is larger than the diameter of the largest intended Conductor.
  • the invention is based on the object basic disadvantage to avoid and a terminal block to propose the type described in the introduction, its handling and constructive design is simple and at the same time has a narrow width in the baying direction.
  • the leader between a cutting edge that penetrates the insulation, and a non-cuttable counter support preferred a counter support, which is also a cutting edge, where both cutting pliers-like without side offset are movable against each other.
  • connection device a cross-sectionally C-shaped one-piece bite sleeve made of a resilient material, the mutually facing bevels formed as cutting edges are. Because these cutting edges are usually mirror-symmetrical are shaped and arranged and made of the same material exist, it is achieved that both cutting edges in the Insulating jacket of the conductor penetrate and contact with of the leader soul.
  • the jaws of the bite sleeve apart, d. H. she form a slot in the relaxed state that is so large that the insulated conductor can be inserted.
  • the pliers legs are made using a Screw or an eccentric pressed against each other, so that the pliers legs then spring into the cutting edges Exercise the clamping direction.
  • the pliers legs spring the bite sleeve together, d. H. inherently the power Apply to cut through the insulation jacket.
  • an eccentric nut which is arranged in the bite sleeve and expands it.
  • a pocket-like on one of the pliers legs Provide formation in which a bending tool can be inserted, e.g. B. a screwdriver, the one Extension of the pliers leg forms.
  • Pliers legs consist of a spring material. In this It is possible to use a pliers leg Eccentric, a screw or the like, to generate the necessary cutting and clamping force.
  • Fig. 5 shows a molded onto a busbar 11 one-piece bite sleeve 12 of C-shaped cross section, the Bends are formed by sharpening as cutting 13.
  • the bite sleeve is made of a spring material and so shaped that, when left to its own devices, pops up so that the slot between the cutting edges unimpeded insertion of what is also designated 8 here insulated conductor allowed.
  • the bite sleeve 12 is one Carry cross sleeve 14 into which a screw is screwed. In this way, the two pliers legs 15 of the Bite sleeve against the elastic preload compressed so that the cutting edges 13 through the Penetrate the insulating jacket 9 and contact the copper core 10.
  • Fig. 7 shows the same bite sleeve 16 as in Fig. 6.
  • a busbar 19 on one of the tong legs stated.
  • the other leg of the pliers points to his Outside a pocket-like projection 20, in which, as shown, a screwdriver 21 with its blade can be inserted. It serves as an extended one Actuating lever with which by pressing down The bite sleeve can be opened.
  • the further example showed instead of a one-piece Bite sleeve a two-part also C-shaped Arrangement of pliers.
  • the pliers legs are limited articulated into one another.
  • Fig. 8 is a cross sleeve with screw Pinch assembly squeezes.
