  • Said useful length (L1) can be substantially equal to the distance between the place of cut of said cable and the front end of said work plane (P), and equal to or less than the longest branch.
  • At least one protection means having a section greater than that of the cable is mounted on at least one section of said cable; it is unwound the predetermined programmed length and it is cut; - At least a first length of said means is mounted on the front end (harness head) of said cable to the point of the most distant branch from said harness head and its front end is clamped on said cable, followed by a second length of said means until the next branch and so on; - A last length of said protection means is mounted on the front end of said cable to the place of the last branch; it is clamped over its entire length on said cable with the exception of its rear end which thus constitutes an opening to prepare the branch and house the front end of said next means and of said branch; - The front end (harness head) of said cable is combed to separate each strand, which is stripped and lined with an electrically conductive coating.
  • Each derivation is prepared as follows: - the predetermined place of the diversion is sought and defined; - the predetermined number of wires making up the bypass strand is selected, the strand is cut and extracted (from the cable). - the strand is untwisted; - a strand of at least two wires is twisted; - the free end of the strand is stripped and lined with an electrically conductive coating; - The strand is positioned relative to its starting point and a protective means is mounted on said strand until its end is disposed in said spread of the sheath tightened on said cable; - the free end of the strand after having been fitted with a connector, and a connection box is plugged into the test socket.
  • Said means of protection is a sheath.
  • Said material may be heat shrinkable.
  • the lining of an electrically conductive coating of the free ends of each strand is carried out by tinning, after removal of the insulation placed on the ends, or else the lining of a coating of the free ends of each strand is carried out by quenching in a tin bath allowing simultaneously the pickling and tinning of said ends.
  • a strand is taken at random for testing, parallel strands are sought, the strands equipped with the connectors are placed in the cell of the head unit according to the indications of the test system, and after verification of the operation, the order is given to move to the next strand or to start recognition again.
  • the means for overmolding is an elastic, waterproof, insulating and vibration-absorbing sealant.
  • All beam manufacturing operations can be performed automatically and repeatedly according to a predetermined program.
  • the invention also relates to an installation for implementing the method described above, characterized in that it comprises a system (D) for rewinding the cable (C) and a worktop (P), carrying all the systems. and apparatus necessary for the manufacture of beams.
  • a system (D) for rewinding the cable (C) and a worktop (P) carrying all the systems. and apparatus necessary for the manufacture of beams.
  • said work surface (P) of a total length (L) can be mounted in series a cable traction device equipped with a device for reading the unwound cable length, a shears or equivalent and an apparatus for selecting, cutting and extracting the strands constituting the derivations of the guides of the kind which allows the threading of the sheaths, said work surface being, moreover, equipped with magazines and net unwinding systems positioning winners, a heating system for shrinking the material of the sheaths, connector stores and fixing devices, connector lugs, optionally pickling and / or tinning baths, test sockets and a recognition and test.
  • the device for selecting, cutting and extracting the strands is, for example, mounted on a longitudinal guide rail parallel to the cable (C), to allow its programmed longitudinal movement.

  • the cable (C) is pulled in the longitudinal direction of the work plane (P) according to the arrow (f1) by a system ( 1) which is, for example, a set of rollers or tracks driven by a suitable drive member.
  • the cable is, for example, a single strand-assembly of the conductive strands of the power currents.
  • the system (1) advances the cable (C) to a shear or guillotine (2).
  • a link (5a) which may be an adhesive tape is placed at a distance (d) from the harness head for prevent untimely untwisting of the strands making up the strand when preparing their front end for connection to the main network.
  • the cable (C) advances along the arrow (f1) by the action of the system (1) over a predetermined length (L1) called for best understanding "useful length".
  • the programmed stopping of the cable (C) is ensured by a reading device incorporated in the system (1) which is, for example, controlled from a central programming member (not shown in the drawing).
  • the total length (L) taken into account is substantially equal to the length of the work surface (P); the distance (d) is therefore less than the length (L2) which is equal to (L - L1).
  • the useful length (L1) is equal to the sum of lengths (L4, L5, L6) of the sections (C3, C2, C1) of the cable (C).
  • the cable (C) is then sectioned by the system (1) which can, for example, be a guillotine acting according to the arrow (f2) in a plane perpendicular to the longitudinal plane of the cable (C).
  • the whole series of beam manufacturing operations is repetitive and can, for example, at least partially be controlled by said central programming member.
  • the connector lugs are supplied from a magazine (10c) for the harness head strands and crimped at (11c).
  • the advancement of the cable (C) along the work surface (P) is facilitated by the use of guide supports (3a, 3b) which are preferably of the type known per se, allowing the sheaths to be threaded ( 13) on the cable (C).
  • a first sheath (134) is unwound from a reel (8a) according to the arrow (f5) by a reel (D) and measuring member (not shown in the drawing) at a length (L4) programmed in advance and it is cut by a cutting device (not shown in the drawing).
  • This sheath (134) is slid over the cable (C) on the "beam head" side to protect, for example, a part (C3) of the cable (C) whose length (L4) is equal to the measured distance from l rear end cut from the cable (C) to the point of extraction of the bypass (20 a). (see fig. 2).
  • the front end of the sheath (134) is tightened on the cable, for example by local heat shrinking of the sheath material by heat input from a heat generator such as an air nozzle (9) hot via a distributor duct (not shown in the drawing).
  • the length (b) of the tight part of the sheath (134) is chosen so as to ensure good tightening on the one hand and to allow the introduction of a sheath (14) for the derivation (20a) on the other leaves in a bloom (16) so that a clearance (j) remains between the sheaths (134, 135) and the sheath (14).
  • the loose part of the following sheath (135) is slid over the section (C2) of the cable (C) over a length (L5) substantially equal to the distance between the branches (20a) and (20b).
  • a third sheath is slid over the section (C1) of the cable (C) over a length (L6) substantially equal to the distance from the branch (20b) to the head of the harness.
  • the sheath (135) is tightened on the section (C2) for example by heat-shrinking its constituent material over the entire length (L5) except on its rear end having a length (a) sufficient to allow the constitution of said open (16).
  • the sheath slipped on the last section (C1) of the cable (C) over a length (L6) is tightened on said section (C1) except on its rear end to allow the constitution of a breakout (16) for prepare the bypass (20b).
  • the head end of the bundle is combed to separate each strand, which is then pickled and covered with a coating, for example by quenching in the pickling and tinning bath (7 c ).
  • the connectors are crimped onto the strands in the crimping unit (11 c ) and the strands and connectors are inserted into the cells of the connection box which is plugged into the test socket (12c).
  • the apparatus (4) for selecting, extracting and cutting the branches of the branches moves in a controlled manner on the guide rail (6) according to the arrows (f3) up to the programmed location provided for the output of a bypass.

  • the derivation (20a) has 7 strands and the derivation (20b) (only) a single strand.
  • the seven strands of the bypass (20a) after extraction are untwisted from said cable (C), then twisted between them, while the single strand of the bypass (20b) is only untwisted.
  • the free ends of each strand are then pickled and filled with an electrically conductive coating, for example by pickling and tinning in the baths (7a) and (7b) respectively.
  • the strands are positioned according to the programmed harness.
  • the sheaths (14) coming from a reel (8b) are measured and automatically slid along the arrow (f5) on the branches so that the rear ends of said sheaths (14) are located in the openings (16) d 'waiting.
