Definitions

  • the subject of the present invention is a method of crimping a contact on strands of a cable.
  • She especially finds her use in the field of electrical connections including those used in the aeronautical field, where the connection between a cable and a contact must be reliable regardless of external conditions to which it is subject.
  • These electrical connections are usually subject to large temperature and pressure variations amplitude due to boarding aircraft that can fly up to 10,000 meters of altitude. For example at the level of an airplane, the temperature can vary between -50 ° C, when in the air, and + 40 ° C when placed on the ground.
  • the object of the invention is to reduce the consequences of the phenomena of differential expansion induced by these temperature variations.
  • the invention provides a method for ensuring a good crimping of the contact on the cable even when these are made of materials distinct.
  • the invention proposes a solution to guarantee the crimping a contact forming a barrel inside which the cable is placed so that the barrel covers both bare strands of the cable and a non-stripped portion of this cable.
  • the soul of a cable is made from single strands that can be made of aluminum in particular for avionics, or copper or other applications. These strands are surrounded by an insulating sheath generally made of a material plastic. The constraint when the cable has strands is that these strands can roll over each other during a crimping operation. In addition, the retention of contact, even crimped, on these divided son is difficult.
  • the object of the invention is to overcome the disadvantages of mechanical strength and electrical continuity by proposing to connect the contact on both the soul namely the strands of the cable and both on the cable sheath.
  • the contact which is intended to receive in the barrel a stripped end of a cable has at a second end a connection termination.
  • the contact has a collar between this termination and the area with the barrel.
  • it is intended to hold the contact inside the crimping tool at the level of this collar.
  • the collar is presented inside a medium retention of the crimping tool.
  • connection strands inside the drum makes it possible to guarantee the connection strands inside the drum while guaranteeing their integrity and tightness of the connection thus made.
  • the tightness of a connection is fundamental to prevent corrosion phenomena.
  • the current connection by the crimping method according to the invention makes it possible to provide connections that withstand temperature variations and also corrosion by salty fogs.
  • the object of the invention is to crimp a contact into which is inserted a stripped end of a cable inside a barrel of this contact. Crimping at a first level, at a first zone of the barrel surrounding strands of the cable by a radial clamping movement of a jaw. And to crimp the barrel along its length along this end of the cable, the closed position of the tools ensuring the first crimping so as to guarantee the position of the strands of the cable by compared to the drum. So when the drum is crimped on its entire length by wire drawing it is ensured that the length of the crimped strands inside the barrel have a length in engagement corresponding to the expected dimensions. Indeed, cable strands are not repelled or broken inside the drum during of the drawing operation.
  • the subject of the invention is a crimping method which provides crimping a contact 1 around one end 2 of a cable 3 by means of a tool crimping 4.
  • the contact 1 is preferably made of a deformable material. he has a first front end 5 intended to cooperate with a complementary device. Moreover, it has a second end rear 6 forming a shaft 7 to receive the end 2 of the cable 3.
  • the first end 5 is a plug intended to cooperate with a socket of the complementary device.
  • the contact 1 has a main axis of elongation 8 according to which are presented for their respective connections on the one hand the first end of the contact 5 and on the other hand the shaft 7.
  • the shaft 7 has a opening 9 perpendicular to the axis 8 and opening into the barrel 7.
  • the inner cavity of the barrel 7 preferably has a frustoconical outer shape such that the diameter of the opening 9 is significantly greater than one diameter of the cable 3, while an inside diameter at the bottom of the cavity is of a diameter slightly less than the diameter of the cable 3 surrounded of its sheath 11, while being slightly greater than the diameter of the strands stripped 10 of the cable 3
  • the contact 1 is made of copper alloy.
  • the cable 3 has metal strands, in particular made of aluminum, and is surrounded by a sheath 11 preferably insulating and plastic.
  • the invention is particularly interesting for this type of connection.
  • the crimping tool 4 has a first jaw 12 and a second jaw 13. These two jaws 12 and 13 can open from to allow the introduction of the contact 1 along its axis 8 between parts of the two jaws 12 and 13 respectively. Preferably, jaws open and close orthogonally to the axis 8. When the contact 1 is correctly placed in the crimping means 4, the first jaw 12 is closed around a tubular portion 14 of the barrel 7.
  • the tubular portion 14 has a tubular outer periphery in the continuity of the frustoconical circumference of the shaft 7, in continuity with the end of smaller diameter of this frustoconical portion. This portion tubular surrounds more particularly the bottom of the drum cavity 7.
  • the second jaw 13 comes to close around the portion truncated barrel 7.
  • the second jaw 13 has chamfered edges of shapes substantially complementary to the shape frustoconical shaft 7.
  • the contact is retained in the crimping tool 4, but it is still free to be slightly moved between these two jaws.
  • Contact retention 1 in the first jaw 12 makes it easy to insert the end 2 of the cable 3 inside the drum 7.
  • the contact 1 preferably has a flange 15 to cooperate with flanges 16 of the first jaw 12.
  • the first jaw 12 has face-to-face flanges 16 'and 16 "between which the flange 15 is retained.
  • the cooperation between the edges chamfered and the frustoconical outer wall also limits the mobility of the contact 1 along the axis 8 inside the crimping tool 4.
  • a jaw such as 12 or 13 comprises respectively one or more movable parts to cooperate together. These parts can come closer and move away from each other to define a space with variable dimension between these two parts. On the other hand these two parts can be adjusted in position one vis-à-vis the other to be properly positioned either in an open position for receive a contact either in a retention position to hold the contact, either in a crimping position to compress walls of the contact on the cable 3. Generally these parts are symmetrical, some compared to others. They come closer and move away from each other according to an axis preferably perpendicular to the axis 8 of elongation of the contact 1. Regarding the second jaw 13, it is also endowed with a translation means for being moved longitudinally along the axis 8.
  • the portion is crimped first tubular 14 disposed between the moving parts of the first jaw 12 in a radial movement of the jaw with respect to the axis 8.
  • the parts of the jaw 12 come closer to each other to come to constrain the portion 14 around the end 17 of the strands stripped 10.
  • the parts constituting the jaw 12 are brought closer to one another according to radially directed forces. The forces are equivalent.
  • the first jaw 12 remains thus embedded in the portion 14, while the second jaw 13 is it moved axially along the axis 8 of way to come to bear against external perimeters 18 of the truncated portion of the barrel 7.
  • the axial displacement along the axis 8 of these two parts causes a progressive crushing of the walls 18.
  • a spacing of the parts 20, 21 is such that a distance between the flanges respectively 19 is slightly greater than the outer diameter of strands stripped 10 and successively of the sheath 11. This provides a crimp by drawing, where the rear shank 7, as shown in Figure 5, is crimped as the bare strands 10 and then on the sheath 11. gets a crimp that still gives a slight look frustoconical barrel 7.
  • the two jaws 12 and 13 are contiguous to each other.
  • the second jaw 13 is gradually moving away from the first jaw 12 to run along its entire length the barrel 7. This second jaw 13 is moved to a termination of the barrel 7, namely up to the opening 9 of the barrel 7.
  • the crimping performed by the first jaw 12 corresponds to a crimp in four or eight points.
  • the parts of the first jaw 12 may for example be two in number and For example, each of them has four pressure points to apply against the outer circumference of the portion 14. Alternatively, it may be plan to turn to present only two pressure points on each part of the jaw 12. In this case, to get the eight crimping points, it is possible to impose a rotation of approximately 45 ° contact 1, and to translate it slightly along the axis 8. In this variant, then one can get a disposition of these eight points of staggered crimping on the outer periphery of the cylindrical section 14. This particular position allows to provide a better resistance of the crimping vis-à-vis axial tensile forces.
  • the crimping means 4 has a trigger that allows to successively engage the first jaw 12 around contact 1 and directly enchaine this insertion of the first jaw 12 in the contact 1 by a displacement of the second jaw 13 along this contact 1 to ensure crimping full.
  • the second jaw 13 automatically returns next to the first jaw 12, and the respective parts of each of the jaws 12 and 13 open again to allow the end of the cable to come out provided with his contact 1 now crimped around.
  • the crimping tool can receive a new contact such as 1 crimp on a new end such as 2.
