Definitions

  • the present invention relates to bent end pieces, more generally called lugs, attached to the ends of electrical conductors to ensure the connection between a distribution source and a device for use.
  • the invention relates, more particularly, to the bent ends of the above type which are used in the electrical ignition harnesses of engines and, more especially still, the ignition harnesses of internal combustion and spark ignition engines , especially for motor vehicles.
  • connection between the supply harness and either the coil, or the distributor, or the spark plugs is effected by means of lugs or bent end pieces when the overall dimensions or the space available require it.
  • end caps are completed by caps made of elastic material, such as an elastomer, provided for enclosing the conductive wire and the complementary connection member of the terminal to achieve a sealed association with infiltration and water splashes and having, in addition, an electrical insulation capacity.
  • the tips which are currently used in the above framework, are parts obtained by stamping.
  • Such end pieces have a bent L-shaped shape, generally at a right angle, comprising a branch for connection with the wire of the bundle and a connection branch.
  • Such a conformation is, in particular, chosen so that the end pieces can also constitute traction members on which the forces to be developed are applied when it comes to disconnecting the wire with either the coil, the distributor, or the candle.
  • the first consists of threading the bent cap onto the conductive wire, then ensuring the crimping or adaptation of a ferrule on the wire, then bringing the cap back into position on the ferrule. After which the assembly formed is checked and, if the wire thus formed does not meet the desired electrical characteristics, all of the elements must be rejected.
  • the second solution consists in crimping the lugs at the ends of a wire, then in threading the caps by subjecting them to a radial deformation sufficient to make them pass, without damage, the bent edge of the lugs.
  • the object of the invention thus makes it possible to carry out the manufacture of an ignition harness wire by first crimping the lugs or end caps on a wire, by controlling the electrical function of the latter and by equipping then such a wire, insofar as it meets the desired standards, with the protective and sealing caps.
  • Another object of the invention is to provide a bent terminal or an electrical connection end piece which has mechanical resistance characteristics in relation to the particular application envisaged.
  • the object of the invention is to provide a bent lug or an electrical connection cap capable of withstanding a tensile force applied to one of the constituent branches without permanent deformation of its own structure, nor degradation of the quality of crimping on the conductive wire, or of the electrical quality of contact of its connection branch.
  • the angled electrical connection end piece comprises a branch 2, called crimping, on an electrical conductor 3, such as that shown in broken lines and forming part, for example preferred, of an ignition harness of a heat engine.
  • the crimping branch 2 comprises a part 4, of substantially semi-cylindrical section, extended by two crimping tabs 5 which can be folded and folded down to be tightened and ensure mechanical resistance with the conductor 3 and indirectly make electrical contact.
  • the crimping branch 2 is connected, by a connecting part 6, to a branch 7 called connection, to a complementary terminal not shown.
  • the complementary terminal can be carried, in particular, by a coil or an electrical distributor of an ignition system controlled by an internal combustion engine of the explosion type, such as those fitted to motor vehicles or by the olive. of a candle.
  • the branch 7 is preferably of the substantially tubular type comprising a part 7a elastically deformable in the radial direction to facilitate adaptation, mounting, maintenance, as well as the electrical connection with a complementary terminal which can be of the male or female type.
  • the elastically deformable part 7a is constituted by two legs 8a which are separated with respect to two homologous legs 8b constituting a rigid part 7b for connection with the connecting part 6.
  • the connecting part 6 is constituted by a curved segment having, at least locally, a section substantially equal to that of the connecting branch 7.
  • the curved segment is further defined by a radius R of center O which , taken at the level of the internal radius of the torus, has a measurement of the order of one to three times the diameter of the section of the branch 7.
  • the curved segment fits exactly, preferably, in the extension of connection branch 7.
  • the curved segment, constituting the connecting part 6, is provided to delimit, at least locally, an envelope of generally toric shape.
  • the connecting part or curved segment comprises a half-shell 9, of substantially semi-cylindrical section, which came directly from stamping during the shaping of the branches 2 and 7.
  • the semi-cylindrical half-shell 9 has curved longitudinal edges 10 and 11, located in the same plane passing, substantially, through the base of the legs 5 and / or 8a-8b.
  • One of the edges of the half-shell 9, for example the edge 10, is associated with a complementary part constituted by a complementary half-shell 12, also of semi-cylindrical shape, which is connected, retained or attached to the half -shell 9 by means of a bridge 13.
  • the half-shell 12 is of the open semi-tubular type and results from a stamping operation carried out, starting from the same blank , to form the assembly described above.
  • the reconstitution of the connecting part 6 with a view to the formation of the toric envelope is obtained by subjecting the half-shell 12 to a folding operation in the direction of the arrow f,. This operation is carried out around or in association with the bridge 13, so as to bring the longitudinal edges 14 and 15 in abutment and in coincidence with the edges 10 and 11 of the half-shell 9.
  • This reconstruction phase is illustrated in fig. 2 which shows that the connecting part 6 is, in fact, in the form of a curved segment forming part of the extension of the branch 7 and defining, up to the conductor 3, a continuous toric envelope from the branch connection to conductor 3, in the example illustrated.
  • the above embodiment therefore makes it possible to thread an elastomeric cap on the branch 7 and to make it travel relative to the endpiece until it is partially threaded on the conductor 3.
  • the curved segment 6 does not have any protrusion or roughness having the effect of requiring a significant distension incompatible with the elastic limit of the cap or behaving like an element or obstacle of a constraining or blunt nature causing the deterioration of the cap by friction or by cutting or removal of the constituent material thereof.
  • connection end piece as described above, therefore makes it possible to envisage the manufacture of an ignition beam wire by initially proceeding to the cut to length of the conductor 3, with the crimping of the end end piece (s). , to control electrical properties ques then, then, to the mounting of the caps intended to definitively equip such a wire.
  • Fig. 3 shows an alternative embodiment according to which it is intended to constitute the curved segment 6 by means of a half-shell 16 of the semi-tubular toric type formed, as said previously, between the branches 2 and 7.
  • the edges 10 and 11 of the half-shell 16 form grooves 17 and 18 opening outwards and formed, for example, by folding and cross-folding the edges 10 and 11.
  • the curved segment 6 also includes a complementary part formed by an independent half-shell 19 whose edges 14 and 15 are folded inwards, towards one another.
  • Fig. 4 shows that, in such an embodiment, the half-shell 19 makes it possible to reconstitute the curved segment so that the latter delimits an O-ring envelope, of substantially constant section, with the same characteristics as those of the previous example.
  • the half-shell 22 is folded, in the direction of the arrow f 1 , around the bridge 21, so that the part 23 is brought to locally reconstitute a toric tubular envelope with the half-shell 20.
  • the free longitudinal edge 25 of the part 23 comes to bear on the internal longitudinal edge 11 of the half-shell 20.
  • the element complementary to the half-shell 26 is constituted by a segment or section of helical spring 30 which is arranged, inside the shell 26, to be maintained and immobilized therein in order to reconstitute the 'O-ring constituting the curved segment 6.
  • the immobilization of the segment or section of helical spring 30 can be obtained, in particular, by means of hooks 31 which are formed, from the longitudinal edges of the half-shell 26, in the connection zones between the latter and the branches 2 and 7.
  • the helical spring chosen to assume the above function, is of the type of those having contiguous turns in a state of rest and in a rectilinear conformation.
  • Fig. 11 shows an exemplary embodiment involving an L-shaped starting blank 34 in a plane.
  • the blank 34 comprises, at a branch of the L, two legs 5 directed opposite one another with respect to an axis of symmetry A-A ', which form, with the common trunk 35, the branch of crimping 2.
  • the common trunk 35 forms, with the legs 8a and 8b, the connecting branch 7.
  • the outer periphery of the common trunk 35, between the legs 5 and 8b and shown in phantom is extended by the tongues 33 in radial arrangement.
  • the tongues 33 have a length such that after forming and rolling to reconstitute the O-ring, they come exactly on the edge 11.
  • the curved segment 6 is always constituted by a half-shell having a direct connection with the branches 2 and 7.
  • this half-shell offers a resis high mechanical strength and can withstand, without risk of deformation, the tensile forces exerted on one of the branches or on the other in the direction of separation of the latter, in particular during maneuvers and manipulations aimed at ensuring the disconnection of branch 7 with respect to the complementary element of the distributor or of the member for using the electrical energy distributed.
  • the terminal described above is produced by cutting and stamping using a tool to be followed from a blank of suitable raw material, such as brass, zinc-plated steel, stainless steel.
  • the complementary part can be made of polyamide or of another plastic or elastomer material suitable as far as the flange 27 is concerned, and as steel or brass wire as regards the spring 30.
