Definitions

  • the present invention relates to the field of starters for heat engines, in particular for motor vehicles, and more specifically to contactors for starters which supply power to the electric motor driving the starter pinion.
  • the contactors of the starters of the state of the art have two roles, on the one hand to move the launcher supporting the pinion by means of a fork so as to allow the gear of the pinion to the crown of the heat engine to be started and on the other hand, supplying the electric starter motor to drive the pinion in rotation.
  • the contactors include a set of coils making it possible to move the movable part of a magnetic core, the movable part of the magnetic core causing both the displacement of the fork and the displacement of a contact device comprising a plate of contact intended to establish electrical contact between supply terminals of the electric motor.
  • crushing spring and return spring springs are placed on either side of the plate so as to force the plate against the terminals when the coils are activated and move the plate towards the terminals and to facilitate the return of the plate to its initial position when the coils are no longer supplied.
  • contact devices of the state of the art generally include a large number of parts, which results in complex assembly.
  • the patent application FR2957711 discloses a contact device for a starter contactor according to the preamble of claim 1. It is in particular known from this patent application means for mounting the rod assembly, springs and stops. For example, in this patent application, there are arrangements with stops mounted on the rod to retain a crushing spring. In one embodiment, there is disclosed a bayonet type washer mounted on the contact rod. This embodiment requires producing an axis with a flattened shoulder and a groove.
  • This embodiment is therefore complex to implement.
  • Other embodiments are described to solve this complex mounting problem as well as a shank without a shoulder.
  • the assembly comprises a claw washer mounted on the contact rod, however with such an embodiment there is a risk with many cycles of use such as for reinforced starters, (that is to say a starter which starts a heat engine which is extinguished voluntarily when the vehicle is stopped, for example a red light) which requires a number of cycles four times higher than 'with a so-called standard starter that the claw washer breaks or recedes towards the fixed core leaving play with the crushing spring causing a malfunction of the starter. Indeed, in such a case, the crushing spring may no longer be functional and therefore no longer ensure contact between the contact plate and the terminals.
  • an embodiment in which a pin is added in the axis to hold a washer forming the stop of the crushing spring.
  • such an embodiment is complex to put in place due to the insertion by force into the shaft of a pin which can break during assembly.
  • such an assembly cannot allow the contact rod to rest on the fixed core. In fact, with such an embodiment in the rest state, it is the wafer which is pressing on the fixed core which can cause it to deform.
  • the spring for crushing the plate against the terminals can be offset with respect to the rod, causing an imbalance of the forces of the spring on the plate against the terminals.
  • the aim of the invention is therefore to provide an inexpensive solution having a simple mounting of the contact device making it possible to reduce the appearance of rebounds when the coils are supplied and when the wafer is moved towards the terminals.
  • the contact device must be reliable to allow the various elements to be held in position even after a large number of starts.
  • the closing clip is in abutment on a closing collar of the contact rod.
  • the closure clip comprises a first peripheral centering edge configured to come at least partially surround the closure collar so as to maintain the closure clip in position around the contact rod.
  • the closure clip includes a centering peripheral edge configured to be at least partially surrounded by the end of the squeeze spring to keep said squeeze spring centered around the contact rod. This helps to keep the spring centered on the contact rod better.
  • the closing clip comprising on each side two peripheral centering edges, one configured to be surrounded at least partially by the end of the crushing spring to keep said crushing spring centered around the contact rod and one to come at least partially surround the closure flange so as to hold the closure clip in position around the contact rod. This ensures good centering of the spring on the contact rod to avoid contact, for example, between the spring and the fixed core.
  • the closing clip is symmetrical. This allows it to be mounted in either direction for easy mounting.
  • the closure collar is integral with the contact rod.
  • the retaining collar is integral with the contact rod.
  • the crush spring is in contact with the contact pad.
  • the crushing spring comprises a coil at the end of the crushing spring in contact with the contact plate, this coil comprising a portion of flat surface perpendicular to the axis of revolution of the crush spring.
  • the closing clip and the contact plate apply a prestress of 45N +/- 10% on the crushing spring.
  • the return spring is held by friction around one end of the contact rod and comes to bear on the retaining collar.
  • the diameter of the hole in the contact plate is greater than the diameter of the closure collar and less than the diameter of the retaining collar.
  • the crushing spring has a greater stiffness than the return spring.
  • the present invention also relates to a starter comprising a contact device.

  • the movable part 9b of the magnetic core 9 is connected to a fork 13 (shown partially) which drives the movement of a pinion starter (not shown) from the starter towards the ring gear (not shown) of the heat engine to be started when the movable part 9b of the magnetic core 9 moves to its active position.
  • the movement of the movable part 9b of the magnetic core 9 in the active position causes the movement in translation with respect to the cover 3 of a contact rod 17 of a contact device 15 between a rest position shown in FIG. figure 1 and an active position.
