Definitions

  • the invention relates to a motor vehicle starter.
  • the invention relates more particularly to a motor vehicle starter, of the type comprising a contactor provided with a movable contact capable of being displaced in translation by electromagnetic means between a rest position, in which the contact is in abutment against an element fixed conductor connected to the vehicle's electrical ground, and towards which it is stressed by elastic return means, and an active position in which the movable contact establishes an electrical connection between a current input terminal, connected to the positive terminal of the vehicle battery, and a starter motor supply terminal, of the type in which means are provided which, when the movable contact is in the rest position, allow electrical contact to be established between the supply terminal and the electrical mass of the vehicle via the movable contact, and of the type in which the elastic return means are arranged. between the movable contact and a terminal support block made of insulating material.
  • the starter motor which includes an inductor winding and an induced winding electrically connected in series, finds itself in an electrical short circuit when the power supply terminal is earthed to the electric ground of the vehicle.
  • the starter motor rotor is then braked by self-induction.
  • the invention therefore aims to provide a device for grounding the power supply terminal which is easy to assemble and which has perfect operating guarantees.
  • the invention provides a starter of the type seen above, characterized in that the movable contact and the supply terminal are electrically connected by elastic return means made of conductive materials.
  • the invention also provides a contactor for a starter in accordance with the teachings of the invention.
  • FIGS 1 to 3 show a starter switch 10 comprising a cylindrical housing 12 of axis XX, in which is mounted an annular winding 14 which, when it is traversed by an excitation current, causes an axial magnetic flux in the contactor, in particular thanks to a polar mass 16, and the winding is then capable of causing the axial displacement of a mobile core 18.
  • the movable core 18 is therefore capable of sliding between a rest position in which it protrudes axially through a first axial end 20 of the contactor 10, and an active position in which, under the effect of the magnetic field induced by the winding. 14, it is almost entirely received inside the winding 14.
  • a helical compression spring 22 resiliently returns the movable core 18 to its rest position.
  • the casing 12 of the contactor 10 is closed at its second opposite axial end 24 by a block 26 for supporting the terminals 28, 30 provided for the electrical supply of the starter motor (not shown).
  • the support block made of insulating material 26 comprises a cylindrical annular skirt 32 which allows its centering and its fixing to the end 24 of the casing 12 of the contactor 10, and a transverse bottom 34 which axially closes the contactor 10.
  • the terminals 28, 30 are substantially diametrically opposite on the bottom 34, on either side of the axis X-X of the contactor 10.
  • the terminals 28, 30 each have a contact head 36, 38 arranged inside the contactor 10, against the transverse bottom 34 of the support block 26 and a connection pad 40, 42, partly threaded and which extends axially. through the transverse bottom 34 so as to open out of the contactor 10.
  • a first terminal 28 is provided to be connected to the positive terminal (not shown) of a vehicle storage battery and the second terminal 30 is provided to receive a power cable (not shown) from the starter motor.
  • the support block 26 is made of insulating material and it is fixed, for example by crimping, to the end 24 of the contactor 10.
  • a movable contact 44 consisting of a substantially rectangular plate, is capable of being moved axially inside the space 45 delimited by the annular wall 32 and the bottom 34 of the support block 26, between a rest position in which it bears against the pole ground 16 of the contactor 10 and an active position in which the movable contact 44 bears simultaneously against the heads 36, 38 of the terminals 28, 30 so as to establish between these two terminals 28, 30 an electrical connection which supplies the starter motor with electric current from the vehicle's storage battery.
  • the axial displacement of the movable contact 44 is controlled by a rod 46, which is guided axially in the pole mass 16, and the displacements of which are controlled by the movable core 18.
  • the movable contact 44 is slidably mounted on the rod 46.
  • the rod 46 controls the movable contact 44 towards its active position by means of a contact spring 48 which bears on one side against a shoulder 50 of the rod 46 and on the other side against the axial face 52 of the movable contact 44 which bears against the pole ground 16 when the contact 44 is in the rest position.
  • a return spring 54 makes it possible to return the rod 46 and the movable contact 44 to the rest position.
  • the return spring 54 is supported at the bottom of a cylindrical housing 55 arranged at the center of the transverse bottom 34 of the block 26 and axially urges a metal washer 56 which is supported against a second shoulder 58 of the rod 46 and against the face axial 60 of the movable contact which also cooperates with the terminals 28, 30.
  • the metal washer 56 is fixed axially on the rod 46 against the shoulder 58 by a claw washer 62 which is force fitted on the axial end 64 of the control rod 46.
  • FIG. 1 represents more particularly a known embodiment of a contactor which makes it possible to connect the power supply terminal 38 to the electrical ground of the vehicle by means of the movable contact 44.
  • a cut and folded sheet metal part 66 which has an end 68 interposed between the contact head 38 of the terminal 30 and the transverse bottom 34, which comprises a connecting strip 70 which extends axially the along the internal face 72 of the annular wall 32 of the support block 26, and which has a second end 74 curved radially inwards.
  • the second curved radial end 74 is intended to cooperate with the face 52 of the movable contact 44 when it is also in contact with the polar mass 16.
  • the tab 66 being permanently in contact with the supply terminal 30, it is at a high electrical potential when the movable contact 44 establishes contact between the two terminals 28, 30.
  • an insulating plate 76 made of insulating material has been arranged between the curved end 74 and the polar mass 16.
  • This plate 76 is pierced in its center with a hole 78 for the passage of the control rod 46 and it also includes a bore 80 through which extends axially a protuberance 82 of the polar mass 16 intended to come into contact with the face 52 of the movable contact 44.
  • the protrusion 82 is located transversely in the same plane as the curved end 74 of the tab 66 so as to allow the movable contact to be, in the rest position, simultaneously in abutment against the protrusion 82 of the polar mass 16 and against the curved portion 74 of the tab 66 so as to make the electrical connection between the power supply terminal 30 and the electrical ground of the vehicle.
  • the curved end 74 which extends radially inwards prevents simple assembly by axial stacking of the various elements.
  • this arrangement requires the production of a protuberance 82 in the polar mass 16, which implies indexing during assembly to position it opposite the bore 80 of the insulating plate 76 and which does not allows a very small contact surface between the movable contact 44 and the pole ground 16.
  • the starter contactor shown in FIGS. 2 and 3 makes it possible to carry out an electrical grounding of the supply terminal 30 of the contactor by means of the return spring 54.
  • a metal tab 84 having an end 86 interposed between the head 38 of the strip 30 and the transverse bottom 34, a connecting strip 88 and an end 90 which extends to the bottom of the cylindrical spring guide housing 55 return 54 arranged in the transverse bottom 34.
  • the movable contact 44 being urged against the contact heads 36, 38 by the contact spring 48 linked to the rod 46, the rod 46 has an axial displacement stroke greater than that of the movable contact 44.
