Definitions

  • the present invention relates to a contactor motor vehicle starter.
  • the contactor comprises a movable contact element, of conductive material electricity whose movements are controlled from a rest position to an active position in which it electrically connects the heads of two fixed terminals of contact.
  • the movable contact element is resiliently recalled towards its rest position and its movements along its actuation stroke with a view to establishing contact power between the two main terminals of the contactor, are controlled by a movable core mounted to slide at inside a set of contactor windings.
  • the movable contact element is for example made in the form of a contact plate which is arranged in a plane substantially perpendicular to its direction of displacement and whose front face turned towards the heads of fixed contact terminals electrically connect these two heads when it reaches its active position.
  • the document DE-A-3.925.152 describes and represents a contactor of this type in which at least one fixed terminal of contact is electrically connected to an auxiliary fixed contact with which the movable contact element cooperates, to its electrical connection with the associated fixed terminal, in an intermediate position between its rest position and its active position.
  • the impact of closing the electrical circuit by the plate contact mobile generally creates contact bounces.
  • the starter does not can't work.
  • the object of the present invention is to provide a new design of a starter contactor of the type mentioned earlier which overcomes these drawbacks.
  • the invention proposes a contactor characterized in that the auxiliary fixed contact extends substantially parallel to the direction of travel of the movable contact element, and in that the movable element of contact cooperates by a lateral edge with the fixed contact auxiliary along its displacement path between said intermediate position and its active position, and cooperates with the head of the fixed contact terminal associated with a portion of transverse surface substantially perpendicular to the direction of its movements and which is delimited by said side edge.
  • the invention also provides a starter for a motor vehicle combustion engine, characterized in that it is equipped with a contactor produced in accordance with teachings of the invention.
  • FIG. 1 shows a contactor 10 intended to equip a vehicle starter (not shown) automobile and which consists essentially of a magnetic casing 12 which receives a fixed set of windings 14 and a fixed pole core 16.
  • the power supply of the windings 14 is likely to cause displacement, from right to the left, considering FIG. 1, of a mobile core 18 which is spring-loaded by a spring 20 towards its position rest illustrated in Figure 1 and which is likely to slide with a control rod 22 slidably mounted in the core 16 and whose free end 24 located at the front of the core fixed pole 16 carries a movable contact element 26.
  • the movable contact element is produced in the form of a movable contact plate of general shape rectangular, the rear face 28 of which is recalled resiliently to its rest position illustrated in Figure 1 in which it is in axial abutment against the front face 30 of the fixed polar core 16.
  • the movable contact plate 26 is recalled towards this position by a return spring 32 which is interposed between the front end 24 of the control rod 22 and the bottom transverse 34 of a cover 36 for closing the contactor which is mounted crimped to the front end 38 of the carcass 12.
  • the movable contact plate 26 is capable of electrically connect the contact heads 40 of two terminals 42 which are terminals fixed in the transverse bottom 34 of cover 36.
  • the contact heads 40 are located inside the cover and bear against the internal face of the bottom transverse 34, each by its annular face 44 which delimits the head 40 relative to the body 46 of the contact terminal 42 which crosses the transverse bottom 34 to allow the connection of the terminals to the motor supply circuit of the starter, as will be explained later in reference to Figures 2 to 6.
  • the rear faces 48 of the two contact heads 40 are located substantially in the same plane perpendicular to the X-X axis of the contactor, i.e. perpendicular to the direction of movement of the movable contact plate 26 which is likely to electrically connect the two terminals 42 when its front face 50 which comes into contact with the faces 48 of the heads 40 of the terminals 42.
  • Each of the terminals 42 is made of electrically conductive material and it is mounted in the cover made of insulating material 36.
  • each of the heads 40 of a terminal 42 is associated with a contact auxiliary fixed 52 which is illustrated in detail in FIG. 2.
  • Each auxiliary contact 52 is a part produced by cutting and folding in a sheet of conductive material.
  • Each auxiliary contact 52 has a terminal annular 54 which is interposed between the annular face 44 of the associated contact terminal 42 and the internal face of the bottom 34 of the closure cover 36 which has a shaped groove additional for positioning the terminal 54.
  • the terminal 54 is extended by a conductive blade 56 which extends longitudinally, that is to say in a direction parallel to the X-X axis of the contactor, along the head of contact 40 and beyond the front face 48 of the head 40.
  • the blade 56 is elastically deformable and it has at its rear free end 58 a portion 60 folded down substantially at 180 ° which constitutes a ramp for cooperate with the corresponding lateral edge 62 of the plate contact mobile 26.
  • the ramp 60 thus extends opposite the edge 62.
  • the movable contact plate 26 When the movable contact plate 26 moves from its rest position illustrated in FIG. 1 towards its active position in which its front face 50 will be in contact with the rear faces 48 of the heads 40 of the terminals contact 42, it first cooperates by its lateral edge 62 with the auxiliary contacts 52 in one position intermediate and therefore before the establishment of the contact through its front face 50.
  • Each terminal 50 may include means (not shown) for its angular indexing in relation to the cover 36 so that it occupies its mounting position illustrated in Figure 1 in which its beak 60 extends in side edge look 62.
  • a starter 64 comprising an electric motor 66, one terminal 68 of which is connected to the electrical ground 70 and the other terminal 72 of which is connected to one of the terminals 42 of the contactor power contact.
  • the other fixed terminal 42 is connected to the positive pole + BAT of vehicle storage battery.
  • the power switch 74 of the assembly of windings 14 of contactor 10 which connects the positive pole + BAT to a midpoint 76 of the set of coils 14, the call coil 15 is connected to electrical ground 70 and of which the other coil 13 is connected to the fixed terminal 42 to which is connected to motor 72.
  • the two auxiliary contacts are also shown. 52 and the mobile contact 26.
  • each auxiliary fixed contact 52 has a resistance specific non-zero clean electric which is schematized by a resistance R in FIGS. 3 to 6.
  • the electric motor 66 is then supplied by the vehicle battery through the two resistors R of auxiliary fixed contacts 52 which are in series in the circuit electric connecting the positive pole + BAT of the battery to the motor 66.
  • the value of the resistors R is sufficiently high so as not to cause rotation of the starter armature.
  • FIG. 6 shows an operation contactor abnormal
  • This malfunction can have two causes.
  • a first cause results for example in the icing of a contact.
  • Terminal 40 connected to the + BAT pole can be find isolated by a layer of frost which prevents the coming in contact with the movable contact plate 26 with this terminal 40 at the end of the actuation stroke.
  • the current 13 which then feeds the motor 66 is lower than the normal current of maximum intensity 12 because one resistors R is then inserted in series in the circuit power supply in terminal 72 of motor 66.
  • the associated auxiliary fixed contact 52 then heats up by Joule effect.
  • thermal conduction terminal 42 with its head 40 heats up to cause the frost to melt, causing it to overlapped, which, after a while, allows restore normal contact between the two movable contacts 26 with the head 40 of the type of that illustrated in FIG. 5.
  • Another cause of the malfunction state illustrated in Figure 6 may be a contact bounce.
  • the design of the contactor according to the invention allows therefore to make the starter quickly operational in the event of contact icing, it allows an initial supply under reduced motor voltage and it removes the harmful effects of contact rebounds.
