Definitions

  • the invention relates to a connection piece with a slot stripping and / or retaining for connection arrangement for one or more several electrical wires.
  • such an arrangement includes a slot for stripping and / or retaining for at least one wire which is formed in a conductive piece of small thickness.
  • One end of the slot is provided a flared mouthpiece intended to facilitate the longitudinal insertion of a wire, transversely to the slot where this wire is to be connected electrically and simultaneously ensuring, in most cases, a cross section of the insulation sheathing the wire.
  • the soul of the thread, locally stripped by the mouth of the slot comes into contact with the edges of this slot which immobilizes it by pressure and which ensures continuity between the core of the wire and the conductive part where the slot.
  • the wire sheath is often wedged simultaneously between the edges a sheath wedge opening which extends in the vicinity and at the look of the retaining slot in an insulating box where the part is housed conductive.
  • the known arrangements are generally calibrated for a range relatively limited wire core diameters for which a holding and connecting the wires by their souls reliably and with specific characteristics. It is therefore necessary to carry out a same layout model with slightly different dimensions to cover the range, known to those skilled in the art, of electrical wires for which it is possible to envisage a connection of this way.
  • connection parts is relatively large. Indeed, the width of these pieces is at a minimum equal to the diameter of the largest diameter wire that can be connected increased in width by the two side walls carrying the edges of the slot.
  • the present invention therefore aims to provide a part of electrically conductive connection, for connection arrangement to stripping and / or retaining slot for one or more electrical wires which has a reduced bulk.
  • the slot is defined by two of the edges of said piece which complete respectively the first two room elements, plans, curves or composite and converging towards said slot.
  • These first elements extend on the same side of the room two second elements of this part which are themselves parallel and joined to each other, according to a U-shaped arrangement, by a connecting element located at one of their ends.
  • connection piece comprises teeth stripping which are respectively arranged on either side of a slit mouth and which correspond to a filling of the sub-assembly formed by a first element and / or by the second element which door.
  • connection of a wire can be made to the stripping teeth level without the wire coming to take place between the second elements.
  • the width of the connection piece can thus be reduced and we can come connect wires whose outside diameter is greater than the width of the room.
  • the connecting element is located on one of the sides of the part which is adjacent to that where the slot extends.
  • said connecting element is advantageously located on the other side of the workpiece with respect to the slot edges which form the slit mouths used for the introduction of wire (s).
  • the connecting element is located on the opposite side of the room which is opposite to that where the slot.
  • the part according to the invention can have at least one slot, delimited by two edges each ending a first element, which itself includes an insertion mouthpiece of wire with two stripped edges each formed on one edge different.
  • a part according to the invention can be associated with a part identical to which it is connected by a common link strip to form a double connection piece.
  • Connection piece 1 with stripping and retaining slot wire presented in Figures 1 to 7 is for example intended to be part a connection arrangement for electric wires where this part is immobilized for example by embedding in a housing provided in a body of insulating material, not shown.
  • this body is often made up of two pieces additional molded insulating material, as provided in particular in document FR-A-2598039 also relating to an arrangement of connection for electric wires.
  • connection piece 1 is for example produced by cutting, localized folding and thinning carried out by stamping on a flank in rigid conductive metal previously cut from a strip, such as than the one, also referenced 1, the cutting of which is presented in FIG. 8 and corresponds to the embodiment of Figures 1 and 2.
  • This sidewall 1 is here symmetrical with respect to a transverse axis XX 'here located at the level of the middle part 2, here called element of connection, narrower than the rest of the flank which is intended to be an area junction on either side of which the two side portions 3A and 3B which border it are folded perpendicular to them at a level symbolized by the axes AA 'and BB' and in the same direction so as to delimit two large parallel faces, here called second elements of room.
  • Said connecting element 2 is then located at one end of the second part elements with which it constitutes a U-shaped structure. The smaller width of the connecting element 2 relative to the rest of the flank is obtained by cutting a strip perpendicular to the axis transverse XX 'on one of the sides of this side.
  • Oblique folds or bends, converging when the connecting part 1 is formed, are made at the level of parts 4A and 4B located on either side of the transverse axis XX 'and beyond the connecting element to form two elements, called first elements of part, which will delimit the stripping and retaining slot of this part 1.
  • These folds are made in a single operation at a symbolized level by an axis CC 'arranged on the edge of the connecting element 2 perpendicular to the transverse axis XX ', they give rise to first elements of planar, curved parts or possibly composites.
  • the part is here assumed to be symmetrical with respect to a plane median on either side of which symmetrically extends the element of liaison. It then comprises at least two second elements folded in the same direction on both sides of this connecting element which unites them so as to be parallel to the median plane of symmetry and the two first symmetrically projecting elements on the same side of the second elements which they extend obliquely to delimit the slot of stripping and / or restraint.
  • edges of the first elements 4A, 4B which are intended to delimit a stripping and retaining slot 6 of the connecting piece 1 are prepared to form two parallel lips 5A, 5B.
  • the lips 5A, 5B are prepared beforehand at the folds and while the side is still flat and the fold at the axis CC 'is produced before the two folds at the level of the axes AA' and BB '.
  • the connecting element 2 is then located on one of the sides of the part which is adjacent to where the slit extends, on the other side of the workpiece lips 5A, 5B.
  • connection piece when folded, has two elements sharp teeth 10A and 10B between which the slot is formed stripping and restraint 6.
  • the latter presents, in terms of its mouth, converging banks 8E and 8F obtained by cutting obliquely from the edges 5A and 5B of the flank which leads to a reduction in width of teeth 10A, 10B, called stripping.
  • the converging banks 8E, 8F are sharpened over at least part of their length to be able to ensure localized stripping of the core 7A of a wire 7 pushed between these strands relative to to which the wire is then at least approximately disposed transversely.
  • the sheath 7B of the wire 7 is then crossed by the teeth 10A and 10B with which the core 7A of the wire comes into contact to be guided up between the wedging lips 5A, 5B of the slot which are at less initially parallel or quasi-parallel.
  • This configuration has the effect of reducing the width of the connection piece by reducing the connecting element 2, since it eventually allows the wire sheath to overflow laterally on either side of the connection piece 1, as shown in Figures 1 and 6.
  • the transverse size of the room is then likely to be less than the diameter of a wire sheathed electric provided for connection to it. It is of course possible to make a double piece by combining two pieces 1 joined by example with alignment by a common bar 9 and oriented in the direction reverse, as already indicated above in relation to FIG. 6.
  • connection piece 1 of this type receives a larger range of wire diameters than that expected with the workpiece connection described in document FR-A-2598039 already cited above. It is then necessary to leave a possibility of spacing at least one of the two second elements 3A, 3B at the free end of the minus this second element in the housing (not shown) of the body insulation where the connection piece 1 is positioned.
  • Connecting an electrical wire to a connection piece 1 by immobilizing the core of this wire between the edges of the slot that comprises this part, supposedly housed in a housing made of insulating material, can be carried out using a hand tool or mounted on a machine.
  • This tool is for example of the type described in the document FR-A-2584538.
  • Another split is likely to be made in a wall of this case opposite the slot 6 of a piece of connection 1 housed in this box. As known, this other slot ensures additional support of a wire by jamming the core of this wire by the edges of the slot 6.
  • connection piece 1 such that mentioned above to a blocking push piece type, not shown, preventing a return of the wire to the mouth of the slot through which it was introduced, as long as the coin this type of blocking pusher has not been released and / or removed.
  • Such a blocking pusher is likely to be constituted by a slide movable from the outside of the case where the part of the connection 1 between a position for which it is possible to insert a wire, between a bearing end of the wire of said blocking pusher and the mouth of the slot 6 of this connection piece and, a position for which wire immobilization is ensured by cooperation of the edges of said slot 6 and by the locking pusher.
  • connection piece according to the invention is shown in Figures 3 to 7.
  • the same references are used subsequently to designate identical elements.
  • edges of the first elements 4A, 4B which are intended to delimit the stripping tooth and retainer 6 of connection piece 1 are prepared to constitute two parallel lips 5A, 5B and in particular cut and thinned to form the banks 8A, 8B of a flared stripped mouth at one end of this slot.
  • the edges 8A, 8B are prepared before folding and while the side is still flat.
  • the folding element 2 is here located on the side of the coin which is opposite to that where the slot extends.
  • the mouthpiece is produced by oblique cutting and stamping of the edges 8A, 8B beyond the lips parallels 5A, 5B at the respective ends of the first elements 4A and 4B at the free end of the teeth 10A, 10B.
  • the mouthpiece obtained allows to locally strip the core of a wire pushed in force at through this mouth by cutting the insulating protective sheath covering this soul.
  • An electric wire 7 is shown wedged between the lips 5A and 5B of the slot 6 by its core 7A beyond the mouth which has allowed the guidance of this soul between these lips, after ensuring a local cutting of the sheath 7B via its edges 8A, 8B.
  • Figure 3 shows a connection piece according to the invention in which are connected two electric wires 7 of small diameter.
  • the wire 7 inserted first into the slot 6 is located at the level of the second elements 3A, 3B and the second wire 7 takes place above the first wire, between the lips 5A, 5B, just below the edges 8A, 8B.
  • Figures 4, 5 and 7 show the connection of an electric wire 7 whose diameter corresponds substantially to the width of the piece of connection.
  • the wire 7 is stripped locally at the mouth by the edges 8A and 8B and comes to take place between the lips 5A and 5B.
  • the sheath 7B then comes to rest on the upper free edges 11A, 11B of the second elements 3A, 3B located on the side of the teeth 10A, 10B.
  • connection piece 1 As shown in Figure 6, it is also possible to come connect an electric wire 7 whose outside diameter is greater than the width of the connection piece 1.
  • the sheath 7B of the wire then comes to rest on edges 11A and 11B while electrical contact is ensured at lip level 5A and 5B.
  • the second elements 3A, 3B as well as the connecting piece 2 gives the connecting piece 1 the necessary elasticity to ensure a good electrical connection at the lips 5A, 5B.
  • the shape of the slit and therefore of the lips and edges, may be different from the shapes shown in the drawing and described above.
