Definitions

  • the present invention relates to ignition equipment for internal combustion thermal engines and, more particularly, it relates to the ignition of internal combustion engines, of the spark-ignition type fitted to motor vehicles. It should, however, be considered that the object of the invention relates, mainly, to ignition equipment for heat engines and, consequently, the invention can be implemented for engines intended to equip stationary equipment or intended to constitute a main or auxiliary source of energy, for example, for boats.
  • Engines of the above type include, for each cylinder, a spark plug which is connected by an electrical conductor to a production source, of the induction coil type.
  • connection is established by means of connection lugs fitted to the electrical cables, intended to be clipped onto the terminals and on which are threaded elastomer caps responsible for maintaining a good electrical connection, as well as a secure mechanical connection while reducing the dielectric losses.
  • Such coils have, however, a disadvantage in that the terminals to be assigned to the ignition of the different cylinders are difficult or difficult to identify, so that a risk of bad connection or permutation is to be considered at the time of assembly conductors connecting said terminals to the different spark plugs.
  • the prior art knows another solution recommended by the French application 90-03 829 describing a connector constituted in the form of a hollow box, open on the top, so as to allow the implantation and the immobilization of the terminal parts of the different electrical conductors, the angled connection terminals of which are engaged in holes in the bottom of the housing.
  • the conductors are immobilized by means of clamps and by filling or coating with resin occupying the useful volume of the housing, except for a substantially central reserve in which the bottom leaves a window for latching a deformation rod. elastic rising from the top of the spool.
  • the bottom of the housing is extended by rigid sleeves which are intended to fit, during assembly, the turrets of the coil terminals, with the interposition of seals intended to assume the function of traditional caps.
  • a risk of inadvertent release, not perceptible visually, is attached to such a mounting, so that the electrical connection established may be imperfect and no longer provide the sealing character normally required.
  • each sleeve with an individual elastomer lining which is easily detachable and lost, due to its very constitution and its simple interlocking mode inside the sleeve, constitutes a major drawback, because it can be the source of two functional problems.
  • the electrical connection may be imperfect if the packing no longer occupies the position assigned to it.
  • the connection although perfect, may prove to be unsatisfactory if the sealing character normally required is not established reliably and durably.
  • the object of the present invention is to propose new means for producing a connector for an ignition circuit of an internal combustion, explosion and and spark-ignition engine, such a connector being designed to eliminate the above drawbacks and allow connection simple, fast, efficient, reliable and durable, whatever the conditions of use of the engine, with in addition provision to the operator of a visual indicator of correct installation, locked or not, of the connector.
  • Another object of the invention is to propose means such that the connector can be manufactured in a unitary form, by simple assembly of the elementary parts according to a possibly automatic cycle free from any manual intervention.
  • Fig. 1 is a perspective of the connector according to the invention.
  • Fig. 2 is a top view according to FIG. 1.
  • Fig. 3 is a bottom view corresponding to FIG. 1.
  • Fig. 4 is a partial section taken on the line IV-IV of FIG. 2.
  • Fig. 5 is a cross section, on a larger scale, taken along the line V-V of FIG. 4.
  • Fig. 6 is a longitudinal section taken, on a larger scale, along the line VI-VI of FIG. 2.
  • Figs. 7 and 8 are side views taken respectively along lines VII-VII and VIII-VIII of FIG. 6.
  • FIG. 9 is a perspective showing, on a larger scale, one of the constituent elements illustrated in FIGS. 10 and 11.
  • Figs. 10 and 11 are sectional elevations illustrating two characteristic positions for placing the constituent element according to FIG. 9.
  • Fig. 12 is a partial perspective of an alternative embodiment.
  • Fig. 13 is a partial sectional elevation showing an advantage of the variant according to FIG. 12.
  • Fig. 14 is a cross section illustrating a development of the invention.
  • the connector according to the invention comprises a hollow body 1 composed of a top 2 provided with a peripheral edge 3 with which it delimits a hollow box 4 open on the bottom.
  • the hollow body can be made of any suitable material and, preferably, by molding in an insulating plastic, such as PBT filled with glass fibers.
  • the edge 3 locally forms a sort of rack 5 delimiting notches or clamps 6 intended for the insertion of the terminal parts 7a of cables or electrical conductors 7, of known traditional design.
  • the connector is provided for the ignition of an engine of the four-cylinder type and comprises, for this purpose, a rack 5 delimiting four notches or clamps 6 for the reception of four cables 7.
  • a different number may optionally be selected, for example for an application to five or six cylinder engines.
  • the top 2 of the connector comprises, from its lower face and in the same direction as the edge 3, sleeves 8 coming from molding which are arranged to present in plan, in particular as shown in FIG. 3, a geometrical layout corresponding to that of turrets 9 rising from the top of an induction coil 10.
  • Such a layout can generally be chosen to have a so-called polarization function, so that a single orientation of mounting opposite is determined.
  • Each sleeve 8 has a tubular, cylindrical shape, comprising, in the peripheral wall 11, an opening 12 whose function appears in the following.
  • the wall 11 is also made to delimit kinds of petals 13 separated from the underside of the top 2, so as to have a capacity for elastic deformation by bending near the extreme edge of the sleeve.
  • the different petals 13, for example three in number in the wall 11, are provided, on their internal face and near their edges separated from the top, with flanges 14 which are aligned parallel to the top 2.
  • Each sleeve 8 is intended for snap-fitting mounting of a cap 15 made of a flexible, insulating and elastic material fitted to the terminal part 7a extending inside the housing constituted by the hollow body 1.
  • the immobilization of each terminal part 7a is ensured by means of notches or pliers or claws 16, possibly of an elastically deformable nature, coming from protruding molding from the hollow body 1, either directly from the top 2, or from the edge 3
  • Each cap 15 comprises a tubular tail 17 intended to tightly enclose the terminal part 7a with sealing.
  • the tail 17 extends radially with respect to a skirt 18 surrounding at a distance a centering end piece 19 of tubular nature, in the center of which the connection branch 20 protrudes from a terminal 21 fitted to the terminal part 7a and embedded or disposed at the interior of the cap 15.
  • the skirt 18 is made so that it can be fitted onto the turret 9 into which the end piece 19 is able to penetrate.
  • the end piece 19 holds a connection element 22 made in any suitable manner, for example in the form of a metal, helical spring, working under compression and intended to cooperate with a contact pad 23 rising from the bottom. from the turret 9.
  • the cap 15 comprises, at the base of the skirt 18 and in the connection part of the latter to the tail 17, a quasi-peripheral groove 25 which is distant from a flat head surface 26 by a measurement h corresponding substantially to the interval between the plane of the flanges 14 and the internal face of the top 2.
  • Each cap 15 fitted to the end part 7a is mounted in the corresponding sleeve by axial engagement with orientation of the tail 17 in the opening 12, so as to make the cap penetrate so that the head plate 26 is brought to bear against the internal face from above 2, when the edges 14 are engaged by snap-fastening in the groove 25 of the skirt 18.
  • the tail 17 is also immobilized by insertion between elastic clamps 16 projecting from the top 2, so that a angular immobilization is carried out simultaneously with an axial holding of each cap.
  • the connector described above constitutes a unitary assembly which can be fitted at the factory to constitute, with the cables 7 and the connection equipment complementary to the cylinder plugs, a harness adapted to each type of engine.
  • the mounting of the unitary assembly which constitutes the connector makes it possible to simultaneously ensure the fitting of the skirts 18 on the various turrets 9 with automatic centering by the end pieces 19, so that an electrical connection is established in a positive and assured manner between each stud 23 and each terminal 21 by means of the elastic element 22.
  • the connector is provided with mechanical locking means which are designed so as to provide a visual appreciation of a simple nested position or of a nested and locked position of the connector on the induction coil.
  • the locking means comprise, according to FIGS. 6 to 8, in the substantially central part of the top 2 corresponding to the implantation of the sleeves 8, a locking well 30 opening in the top 2 by an inlet 31.
  • the well 30 is delimited by two elastically deformable tongues 32, established parallel to each other and extending from the inner face of the top 2 over a length greater than the height H of the edge 3 and the length of the sleeves 8 and the skirts 18.
  • the tongues 32 comprise, at the end and on their external face, engagement projections 33 intended to cooperate with clearances 34 delimited by rigid lugs 35 rising from the top of the coil 10.
  • the tongues 32 also include, on their internal faces facing each other and near their free ends, locking ramps 36 leading to abutment heels 36a.
  • the internal faces of the elastic tongues 32 are also provided, facing and close to the top 2, with two shoulders 37 each consisting of an inclined ramp 38 originating substantially from the top 2 and ending in an abrupt face 39 .
  • the locking well 30 is intended to receive a locking key 40 formed, as can be seen in FIG. 9, by a U-shaped pin whose cross-sectional dimensions correspond to those of the inlet 31.
  • the pin has a core 41 connecting, in particular by means of inclined faces 42, two deformable arms 43 elastically.
  • the branches 43 each comprise on their external surface a double step 44 delimiting in a way two grooves or notches 45a and 45b.
  • the notch 45a is defined by two V-shaped surfaces 46 and 47, while the notch 45b is constituted by an inclined surface 48 leading to an abutment edge 49.
  • One of the branches 43 is provided with a head return 50 whose the function appears in the following.
  • the key 40 is normally engaged in the locking well 30 in a waiting position, as illustrated in FIG. 10.
  • This stable, so-called unlocked, waiting position is determined by the engagement of the shoulders 37 in the notch 45a with abutment for the extraction of the pin by the cooperation of the faces 39 and the edges 49.
  • the sides 42 are located at a distance from the ramps 36, while simultaneously the head return 50 projects externally above 2 to constitute a visual witness.
  • the skirts 18 are simultaneously fitted onto the turrets 9 and the end portions of the tongues 32 are engaged between the rigid tabs 35.
  • the bending necessary for this engagement is authorized by the withdrawal of the pin, the sides 42 are distant from the ramps 36.
  • the projections 33 penetrate into the recesses 34 and confer a position of waiting and temporary holding allowing, if necessary, rapid disengagement, in the case of a verification required.
  • the key 40 is fully engaged inside the well 30 and provides the operator, by simple visual assessment, with certainty of correct mounting and duly established connection between the various turrets and the caps which correspond to them.
  • Fig. 12 shows in perspective a variant which consists in providing the underside of the top 2 and, for example in a direction parallel to the tongues 32, with a bar 51 extending between two sleeves 8.
  • the end part of the bar 51 is cut out by a notch 52 intended to fit a shoulder 53 of the tab 35 in the locked nested position of the connector.
  • the second tab 35 is shaped to comprise, from its shoulder 53, an extension 54 which constitutes an engagement stop for the bar 51, in the case where the connector is presented in an unsuitable manner, for example with a 180 ° reversal in its plan.
  • the bar 51, the notch 52, the shoulder 53 and the extension 54 form polarizing means preventing any reversal of the mounting direction and thus opposing a risk of permutation of connection between the terminals and the conductors, like this is illustrated in Fig. 13.
  • the tongues 32 could rise from the top of the coil 10 to cooperate with rigid tabs 35 formed by the top 2 at the edge of the well 30 capable of receiving the key 40.
  • Fig. 14 shows a development of the invention consisting in mounting a profile 55 on the rack 5, so as to close the notches 6.
  • the profile 55 can, for example, be locked by latching branches 56 in through holes 57 which are arranged in the top 2.
