Definitions

  • the invention relates to a contactor for a starter of motor vehicle comprising improved means of protection of an electronic circuit.
  • the invention relates more particularly to a contactor, of the type comprising a movable magnetic core which moves axially in the center of a winding and acts on a rod of which a front end controls the movements of a contact plate capable of electrically connecting two contactor terminals, of the type in which the control rod extends axially forward through an orifice of a fixed transverse core of the contactor which is arranged axially in front of the winding, of the type in which the contact plate is received inside a cover arranged at the front of the winding, and of the type in which an electronic circuit is arranged in the cover, between the fixed magnetic core and a bulkhead separation which is crossed by the control rod.
  • the electronic card is arranged in a compartment of the cover which is delimited, at the rear of it, by a partition of separation.
  • this compartment is not waterproof because that the contact plate displacement control rod passes axially through this compartment at its center.
  • the invention provides a contactor, of the type comprising a core moving magnetic which moves axially in the center of a winding (12) and which acts on a rod which controls the displacements of a contact plate capable of connecting electrically two contactor terminals, of the type in which the control rod extends axially forward through a orifice of a fixed transverse core of the contactor which is arranged axially in front of the winding, of the type in which the plate contact is received inside a cover arranged at the front of the winding, and of the type in which an electronic circuit is arranged in the cover, between the fixed magnetic core and a partition which is crossed by the control rod, characterized in that the partition wall has a transverse wall and an axial shaft in which the rod slides control, and in that the barrel opens forward forwards from the transverse wall, and backwards, behind the core transverse fixed.
  • FIG. 1 shows a contactor 10 for an electric starter for a motor vehicle.
  • Contactor 10 includes an inductor winding annular 12 of axis A1 which is arranged in a housing 14 substantially cylindrical and which is wound on a body of coil 16.
  • a mobile magnetic core 18, substantially cylindrical, can slide axially in the center of the winding 12 between a remote rest position, which is shown in Figure 1, and an active forward position (not shown) in which the movable core 18 has moved towards the left considering figure 1 under the effect of a field magnetic created by the coil 12 traversed by a current electric.
  • the field lines created by the winding 14 are close again thanks to the presence of a fixed magnetic core 46 which is arranged transversely at the front of the winding 12.
  • the mobile magnetic core 18 causes the meshing a starter pinion (not shown) with a crown gear of a heat engine (not shown) of the vehicle.
  • the movable core 18 causes the axial displacement of an axial rod 20 of the contactor 10 which controls the axial movement of a contact plate 22 from a retracted position of rest, shown in FIG. 1, to an active forward position (not shown) in which the contact plate 22 bears axially towards the front against the heads 24, 26 of two terminals 28, 30 one of which is connected to a vehicle storage battery and the other is connected to an electric starter motor. So, in the active position, the contact plate 22 causes the starter motor power supply which is then likely to cause the combustion engine to rotate vehicle to allow it to start.
  • the contact plate 22 and the heads 24, 26 of terminals 28 and 30 are arranged in a cover 32 which closes, at the front, the housing 14 of the contactor 10.
  • the contact plate 22 and the terminals 28, 30 are received in a front compartment 34 of the cover 32 which is substantially rectangular in shape, while a rear compartment 36 of cover 32, of cylindrical shape, allows the junction of the cover 32 with the housing 14 of the contactor 10.
  • the contactor 10 comprises a card with printed circuit 38 which extends in a transverse plane and which is received inside the rear compartment 36 of the cover 32.
  • the printed circuit board 38 carries an electronic circuit of control of the power supply to the field winding 12.
  • the rear compartment 36 is axially delimited inside the cover 32 on the one hand, at the front, by a transverse wall 42 of a partition of separation 44 and on the other hand, at the rear, by the core fixed transverse magnetic 46.
  • the front compartment 34 of the cover 32 is axially delimited at the rear by the transverse wall 42 of the partition 44 and, at the front, by a wall transverse front 50 through which extend, axially outwards, the cylindrical body threaded each of the terminals 28, 30.
  • control rod which connects the core movable magnetic 18 to contact plate 22, crosspiece axially the rear compartment 36 of the cover 32, passing through in particular the fixed transverse magnetic core 46 through an axial orifice 52 thereof.
  • the partition 44 has an axial shaft 54 substantially tubular which allows to make the rear compartment 36 appreciably waterproof compared to the front compartment 34 of the cover 32 and relative to the central bore 56 of the body coil 16 in which the mobile magnetic core 18 moves.
  • the axial shaft 54 has the shape of a cylindrical tube stepped which delimits an internal bore 59 comprising a segment rear 58 and a front segment 60 of enlarged diameter with respect to rear segment 58.
  • the bore internal 59 of the axial shaft 54 opens axially forwards in front of the transverse wall 42, that is to say in the front compartment 34 of cover 32, and towards the rear, in the orifice 52 of the fixed magnetic core 46, so that the internal bore 59 of the barrel 54 forms an axial passage connecting the internal bore 56 of the coil body 16 in the front compartment 34.
  • the rear axial end 62 of the barrel 54 has an internal radial collar 64 which delimits a face transverse annular 66 turned towards the rear.
  • the internal radial collar 64 is intended to be received inside the orifice 52 of the magnetic core transverse fixed 46 while the annular transverse face 66 is intended to bear axially rearwards against a front face 68 of this fixed core 46.
  • the transverse wall 42 of the partition of partition 44 is intended to bear axially towards the front, by a peripheral edge 70, against a face internal transverse 72 of the cover 32 which is turned towards the rear and which delimits the two front compartments 34 and rear 36 of the cover 32.
  • the transverse wall 42 has substantially the shape of a rectangle similar to the cross-sectional shape of the front compartment 34, but slightly larger.
  • the partition 44 is tight axially between the cover 32 and the fixed magnetic core 46, itself secured to the housing 14, so that the compartment rear 36 is isolated from the front compartment 34 and from the bore 56 of the coil body 16.
  • the rear compartment 36 which is traversed axially through the barrel 54, is therefore substantially annular, so that the printed circuit board 38 must also be annular. From this done, it has a central passage for the barrel 54.
  • a rear section 74 of the control rod 20 is guided in axial sliding in the rear segment 58 of the internal bore 59 of the axial shaft 54.
  • the control rod 20 is extended axially to the front by an intermediate section 76 on which the plate contact 22 is mounted axially movable, and on which it is stressed axially forwards by a compression spring 78.
  • the spring 78 is interposed axially between a collar external radial 80 arranged at the rear of the intermediate section 76 and a rear face 82 of the contact plate 22.
  • stiffening ribs 86 which extend in axial planes on each side transverse front and rear of the wall 42.
