Definitions

  • the present invention relates to a insulation displacement connector suitable for a flat cable of the type comprising several insulated electrical wires or several bare conductors, embedded in an insulating sheath, and comprising a base, a cover arranged to be adapted on said base and connection claws, the number of which is at least equal to the number of insulated electrical wires or bare conductors, these connection claws being mounted inside a space defined by the base and the cover and arranged to accommodate said flat cable, and provided with '' at least one insulation displacement contact member.
  • the document EP-A-470.887 describes a branch connector for flat cable, in which the insulation displacement contact has an H-shaped structure secured to an intermediate support. The end of each branch is cut at a bevel to form a flared entry. The mounting of such a connector is complicated.
  • connectors of the insulation displacement type which are usually used to ensure simple and rapid electrical coupling of individual electrical wires or pairs of wires, used for example in telephone installations, with terminals. connection.
  • the thickness of the insulating layer surrounding the conductor is small and the conductor itself is fragile.
  • the contact members housed inside the known connectors have the function of nicking the insulation without injuring the conductor to ensure an efficient and reliable electrical connection.
  • These connectors are not suitable for flat wires and can only be used for individual wires and not for layers of wires embedded in a flat insulating tape.
  • the present invention proposes to overcome this drawback and to provide a connector making it possible to efficiently and reliably connect cables for transporting electrical energy comprising several electrical wires arranged in a sheet.
  • the base and the cover are respectively provided with grooves respectively separated by longitudinal bulges and longitudinal ribs, these grooves being arranged to cooperate in pairs and housing one of said electrical wires, and the longitudinal bulges and the longitudinal ribs being arranged to cooperate and bear on connecting bridges separating the wires of the flat cable.
  • the insulation displacement connector 10 essentially consists of a lower part or base 11 and an upper part or cover 12 arranged to be fitted so as to enclose a flat cable 13.
  • This cable consists, in the nonlimiting example shown, of three insulated wires 13a, 13b and 13c coated in a layer of insulating synthetic material which surrounds the three wires and forms two connecting bridges 14.
  • the base 11 of the connector 10 has a profile suitable for receiving the cable 13. For this purpose, it has three grooves 15 which define receiving cells of the three wires 13a, 13b and 13c. These grooves 15 are separated two by two by two longitudinal bulges 16 whose summits serve as support for the connecting bridges 14 of the cable 13.
  • the cover has a similar geometry and has three grooves 17 intended to receive the wires 13a, 13b and 13c of the cable 13, and more specifically the upper half of these wires. The grooves are separated by longitudinal ribs 18 which bear on the bridges 14.
  • connection claws 19 which are arranged to ensure electrical coupling of the conductors 20a, 20b and 20c of the corresponding wires 13a, 13b and 13c with terminals integral with this connector.
  • These claws are mounted inside the cover 12, preferably by snap-fastening in housings provided for this purpose and produced by molding.
  • the base 11 has two raised lateral edges 21 each provided with at least one central notch 22. These two notches have a profile complementary to that of two lateral extensions 23 of the cover 12. When putting in place place the cover on the base, the lateral extensions 23 engage in the central notches 22.
  • the raised lateral edges 21 of the base 11 have the form of gantries 24 in U whose upper segments 25 are arranged to cooperate with protrusions 26 of the cover, having a triangular section to ensure a snap-in during the positioning of the cover on the base and then a locking in position of this cover.
  • the protrusions 26 have an inclined ramp 26a which constitutes an attack flank and which cooperates with the inclined edge 25a of the upper segments 25 of the gantries 24.
  • grooves 15 is not limited to three, but can extend to any number, in particular to five, when the cable is intended for convey three-phase electric current and has five coated wires.
  • FIG. 5 shows the cover 12 fitted with three double connecting claws.
  • One of these claws is represented by the perspective view of FIG. 6.
  • These three claws which correspond to the three wires 13a, 13b and 13c of the cable 13, are mounted respectively in the three grooves 17 and more particularly in delimited niches 30 inside these gorges.
  • These niches 30 are delimited by the longitudinal ribs 18, the lateral edges 31 of the cover 12 and transverse partitions 32.
  • the claws are forcibly engaged in these niches whose walls are all made in one piece by molding during the manufacture of the lid.
  • Each claw 19 has a base 33 which carries two insulation displacement contact members 34.
  • the base 33 and the two contact members are made of a metal part by bending stamping.
  • Each insulation displacement contact member 34 comprises two parallel branches 35 and 36 spaced from one another by an average distance which is equal to or preferably slightly less than the diameter of the conductors 20a, 20b and 20c of the wires 13a, 13b and 13c.
  • the contact members 34 are integral with two opposite sides of the base 33 and have an orientation substantially perpendicular to the plane of the base 33.
  • the profile of the insulation displacement contact members 34 appears in FIG. 7.
  • the opposite branches 35 and 36 have at their free end a point 37, 38 which allows penetration of said members into the thickness of the insulation which surrounds the conductors of the wire. .
  • This point is connected to a recessed section 39, 40 which defines with the corresponding section of the other branch a slightly enlarged area 41 of the slot defined between the two branches 35 and 36.
  • FIG. 8 and 9 illustrate the function of the contact members 34 in an initial phase and a final phase of connector use.
  • the phase represented by FIG. 8 it is assumed that the external insulation of the cable has already been perforated by the tips 37 and 38 which have also penetrated inside the insulating layer surrounding the conductor 20a of the wire 13a. The inner edges of these points come into contact with the conductor, which has the effect of slightly separating the two branches 35 and 36 from the contact member 34 when the operator continues to push it in, that is to say say to engage the cover carrying this contact member on the base of the connector.
  • FIG. 9 shows that this relative movement of the conductor 20a and of the contact member 34 has the effect of slightly deforming this conductor which is finally positioned in the enlarged zone 41, defined with reference to FIG. 7. Thanks to this deformation and with the existence of the enlarged zone, the electrical coupling between the contact member and the conductor is carried out satisfactorily and without this being necessary to carry out a preliminary stripping.
  • connection claws are advantageously made of an electrically conductive material, such as for example a copper-beryllium alloy which achieves a good compromise between electrical conductivity, elasticity and creep resistance.
  • connection terminals can be fitted to the connector. They can be of the screw, solder, crimp, etc. type.
  • This connector is that it can be placed anywhere on the cable and that it allows electrical connection to this cable in an efficient, fast and safe manner, without direct intervention on the cable. .
