Definitions

  • the invention relates to a vehicle starter. automobile.
  • the invention relates more particularly to a starter of a motor vehicle, of the type comprising a contactor provided with a movable contact capable of being moved in translation by electromagnetic means between a rest position, in which the contact is pressing against a fixed conductive element connected to the electrical ground of the vehicle, and to which it is requested by means of elastic return, and an active position in which the contact mobile establishes an electrical connection between a terminal current input, connected to the positive terminal of the battery vehicle, and a starter motor supply terminal, of the type in which means are provided which, when the mobile contact is in rest position allow to establish a electrical contact between the supply terminal and earth electric vehicle via the mobile contact, and of the type in which the elastic return means are arranged between the movable contact and a support block for terminals made of insulating material.
  • the starter motor which has a inductor winding and an induced winding electrically connected in series, finds itself in an electrical short circuit when the power supply terminal is earthed vehicle.
  • the starter motor rotor is then braked by self-induction.
  • the invention therefore aims to provide a device for the earthing of the power terminal which is easy to assemble and which offers perfect guarantees of operation.
  • the invention provides a starter of the type seen previously, characterized in that the movable contact and the power supply terminal are electrically connected by said elastic return means made of conductive materials.
  • Figures 1 to 3 show a contactor 10 of starter comprising a cylindrical casing 12 of axis X-X, in which is mounted an annular winding 14 which, when traversed by an excitation current, causes in the contactor an axial magnetic flux, in particular thanks to a polar mass 16, and the winding is then likely to cause the axial displacement of a movable core 18.
  • the movable core 18 is therefore capable of sliding between a rest position in which it exceeds 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 coil 14, it is almost fully received inside the coil 14.
  • a helical compression spring 22 recalls elastically the movable core 18 towards its rest position.
  • the casing 12 of the contactor 10 is closed at its second opposite axial end 24 by a block 26 of support terminals 28, 30 provided for the motor power supply starter (not shown).
  • the insulating material support block 26 has a cylindrical annular skirt 32 which allows its centering and its attachment to the end 24 of the casing 12 of the contactor 10, and a transverse bottom 34 which axially closes the contactor 10.
  • Terminals 28, 30 are substantially diametrically opposite on the bottom 34, on either side of the X-X axis of the contactor 10.
  • Terminals 28, 30 each have a contact 36, 38 arranged inside the contactor 10, against the transverse bottom 34 of the support block 26 and a stud connection 40, 42, partly threaded and which extends axially through the transverse bottom 34 so as to lead to outside of contactor 10.
  • a first terminal 28 is provided to be connected to the positive terminal (not shown) of a battery vehicle batteries 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 plate substantially rectangular, can be moved axially inside the space 45 delimited by the wall annular 32 and the bottom 34 of the support block 26, between a rest position in which it bears against the mass pole 16 of contactor 10 and an active position in which the movable contact 44 is simultaneously supported against the heads 36, 38 of the terminals 28, 30 so as to establish between these two terminals 28, 30 an electrical connection which provides power to the starter motor 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 polar mass 16, and whose movements are controlled by the movable core 18.
  • the movable contact 44 is mounted sliding on the rod 46.
  • the rod 46 controls the movable contact 44 towards its active position via a contact spring 48 which is supported 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 is in abutment against the polar mass 16 when the contact 44 is in the rest position.
  • a return spring 54 allows the rod 46 to be brought back and the movable contact 44 in the rest position.
  • the return spring 54 is supported at the bottom of a cylindrical housing 55 arranged in the center of the transverse bottom 34 of block 26 and axially urges a metal washer 56 which is in abutment against a second shoulder 58 of the rod 46 and against the axial face 60 of the movable contact which cooperates by elsewhere with terminals 28, 30.
  • the metal washer 56 is axially fixed on the rod 46 against the shoulder 58 by a claw washer 62 which is force-fitted onto the axial end 64 of the rod command 46.
  • FIG. 1 more particularly represents a mode of known embodiment of a contactor which makes it possible to connect the terminal supply 38 to the vehicle's electrical ground by via mobile contact 44.
  • a piece of cut sheet metal is provided and folded 66 which has one end 68 interposed between the head contact 38 of 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 block of support 26, and which has a second end 74 curved radially inward.
  • 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.
  • This plate 76 is drilled in the center of a hole 78 for the passage of the control rod 46 and it comprises also a bore 80 through which extends axially an outgrowth 82 of the polar mass 16 intended to come in contact with the face 52 of the movable contact 44.
  • the outgrowth 82 is located transversely in the same plane as the curved end 74 of the leg 66 of so as to allow the movable contact to be in the position of rest, simultaneously pressing against the outgrowth 82 of the polar mass 16 and against the curved part 74 of the tab 66 so as to make the electrical connection between the supply terminal 30 and the vehicle's electrical ground.
  • the curved end 74 which extends radially inwards prevents simple mounting by axial stacking of the different elements.
  • this arrangement requires the realization of a outgrowth 82 in the polar mass 16, which implies a indexing during assembly to position it opposite of the hole 80 of the insulating plate 76 and which does not allow that a very small contact surface between the movable contact 44 and the polar mass 16.
  • the starter switch shown in Figures 2 and 3 allows for electrical grounding of the terminal supply 30 of the contactor via the spring reminder 54.
  • a metal tab 84 comprising a end 86 interposed between the head 38 of the strip 30 and the transverse bottom 34, a connecting strip 88 and one end 90 which extends to the bottom of the cylindrical guide housing 55 of the return spring 54 arranged in the transverse bottom 34.
  • the electrical connection is like this made between the supply terminal 30 and the pole ground 16 which is to the electrical ground of the vehicle via tab 84, return spring 54, metal washers 62, 56 and by the mobile contact 44.
  • the movable contact 44 When the starter is requested by the driver, the movable contact 44 is biased by the control rod 46 towards its active position which is represented in FIG. 3 and in which the movable contact 44 is supported by its axial face 60 against terminals 28, 30.
  • the movable contact 44 being urged against the heads of contact 36, 38 by the contact spring 48 linked to the rod 46, the rod 46 has a greater axial displacement stroke to that of the mobile contact 44.
