Definitions

  • the present invention relates to electrical connection modules with so-called self-stripping or insulation displacement contact terminals intended to be connected to flat cables and also relates to the terminals themselves and the methods of assembling such modules.
  • the terminals are formed by assembling two sheet metal elements forming blade receiving passages aligned in the plane of the terminals.
  • Such contact terminals do not guarantee satisfactory electrical contact and risk deformation if they are abused.
  • Document DE-U-8 615 615 describes a contact terminal having two elastic contact blades and having, at the rear, crimping lugs, which may have, at the rear, means for moving insulation.
  • Document FR-A-2656469 shows an electrical contact terminal in which the stripping flanks are oriented orthogonally to the bottom of the terminal, that is to say according to a conventional arrangement.
  • the present invention aims in particular to provide a terminal contact meeting better than those previously known the requirements of practice for connection to a ribbon cable; it also aims to provide a connection box comprising on the one hand an insulating box, on the other hand such contact terminals guaranteeing satisfactory electrical contact with the blades of a complementary connector and making it possible to ensure a connection in a simple manner by stripping or displacement of insulation.
  • the invention proposes in particular a contact terminal according to claim 1 and a connector module according to claim 2.
  • the invention also provides a method of connecting such a module to a flat cable, according to claim 5.
  • the particular embodiment of the invention which will be described uses electrical contact terminals in one piece, the front part of which has a comparable constitution. to that described in document FR-A-2 621 180.
  • This terminal can be regarded as having a front part intended to receive a male contact blade 12, an intermediate part, and a rear part constituting the barrel to be crimped.
  • the front part of the terminal 10 has a cage shape having a bottom 22 and two sides 24 with double walls.
  • Each side 24 comprises an external wall 26 and an internal wall 28.
  • Each external wall 26 is produced by folding at 90 ° an original blank.
  • the internal wall 28 is connected to the external wall by a 180 ° fold.
  • Each internal wall 28 is connected to the corresponding external wall 26 only in its rear part, so that the front zone of each internal wall constitutes an elastic contact blade intended to rest on the male contact blade 12.
  • the part of the walls 26 and 28 close to the 180 ° fold constitutes a cage ceiling.
  • windows 50 intended to allow the terminal to be immobilized in an insulator, using a locking finger, not shown, which may have any of the constitutions usually used at the time. current.
  • Each outer wall 26 is provided so as to retain the elastic contact blade of the corresponding inner wall in prestress.
  • the outer walls shown include a flap 30 folded back, absorbing the elastic force which tends to bring the contact blades together.
  • An intermediate part has two sides 32 for moving the insulation, formed by cutting and folding at 90 ° so as to form wings oriented perpendicular to the direction of elongation of the contact, delimiting corridors 34 having a converging entry.
  • the part of one of the sides situated between the wings is placed in the extension of the ceiling of the cage and the other side is in the plane of the bottom 22 of the cage.
  • the rear part of the contact terminal has two tabs or tongues 16 which are in the extension of the bottom and the ceiling and are intended to be crimped or shrunk onto the insulation of a conductor belonging to a ribbon cable.
  • FIG. 3 to 5 A possible sequence of operations for connecting a flat cable to contact terminals contained in a module is illustrated in Figures 3 to 5, in the case of a module intended for a four-conductor ribbon cable.
  • the insulating module 52 containing four contact terminals 10 of which only the cutting flanks are shown, is placed in a housing of corresponding shape of an anvil 54.
  • the ribbon cable 56 to be connected is laid on the displacement flanks insulation.
  • a blank holder 58 descended on the anvil.
  • This blank holder has edges intended to come to bear against the anvil and intermediate partitions 60 in the form of a comb intended to cut the flat cable and to be inserted between the flanks of adjacent terminals.
  • These partitions and the internal faces of the edges have a shape such that they are applied against the flanks and absorb the forces which tend to spread them apart during the forced engagement of the insulated wires of the cable between the flanks.
  • insulation displacement punches 62 and punches 64 of hooping of the rear fingers are pressed through the hold-down. As shown in Figure 4, these punches individually push the conductors. Their travel is limited by means not shown at a level such that it does not risk causing undue deformation of the contact terminals. It is possible to provide, in addition to the insulator displacement punches 62 and punches 64 for crimping the tabs 16 on the insulator, punches 66 for holding the individual conductors 68 during connection.
  • the punches are reassembled. Then the blank holder is removed, so as to release the module-cable assembly in ribbon form.
  • the module can then be fitted with a snap-on cover so as to constitute a complete connector.
  • This cover can have any of the well-known constitutions, it is not necessary to describe it in detail.
  • the contact terminals can all be identical or they can, as shown in Figures 3 and 4, be of different sizes, at least as regards the intermediate and rear parts.
