Definitions

  • the invention relates to a carcass contactor for a motor vehicle starter and a starter equipped with such a contactor.
  • a contactor for a motor vehicle starter comprises a movable contact capable of being displaced in translation between a rest position, in which the contact bears against a fixed conductive element connected to a polar mass of the vehicle. , and an active position, in which the movable contact establishes the electrical connection between a current input terminal and a power supply terminal of the starter motor.
  • the shaft of the electric motor rotates a launcher with a pinion, which meshes with a starter ring, rotatably connected to the engine of the vehicle, to start said engine.
  • the input and output terminals are carried by a hollow-shaped support block forming a cover made of insulating material.
  • the contactor comprises a winding with at least one winding for controlling the displacement of a movable core of the contactor, displacement which has the consequence, on the one hand, of causing at the end of the race the power supply of the electric motor of the starter and, d on the other hand, to cause, via a pivoting fork hitched to the movable core and engaging with the launcher, the movement of the starter gear for meshing with the toothed starting ring gear.
  • FIG. 1 shows such a contactor.
  • this contactor comprises a carcass 1 of magnetic material, conventionally made of solid soft iron or sintered.
  • This carcass visible only in FIG. 2 forms a cylindrical casing 1 sealingly closed by the cover 6.
  • the annular winding 4 with one or two windings is mounted in this casing 1, which, in combination with the cover 6, protects the interior of the contactor vis-à-vis the external aggressions and which ensures a return to the mass.
  • the annular winding 4 when traversed by an excitation current, causes in the contactor an axial magnetic flux, in particular thanks to a polar mass 2 forming a fixed core and mounted at one of the axial ends of the winding 4.
  • the winding 4 is then capable of causing the axial displacement of the mobile core 3 of magnetic material just like the fixed core 2.
  • the movable core 3 is thus capable of sliding between a rear rest position in which it protrudes axially through a first axial end of the contactor casing, and an active front position in which, under the effect of the induced magnetic field. by the winding 4, it is almost entirely received inside the winding 4.
  • the first axial end is formed by the bottom 1a centrally perforated of the carcass 1, which comprises a tubular portion 1b of axial orientation connecting to the outer periphery of the bottom 1a of transverse orientation.
  • a helical compression spring resiliently removes the movable core towards its rest position by resting on the outer rear face of the bottom 1a facing away from the winding 4.
  • This bottom 1a also serves, thanks to its central opening, to support to a guide tube also carried by the winding support 4.
  • the guide tube is at its inner periphery in intimate contact with the outer periphery of the movable core 3 of cylindrical shape.
  • This core is centrally provided with a blind hole for housing an actuating rod and a tooth against tooth spring acting between the movable core 3 and a head of the rod protruding from the movable core to carry a hinge axis for the starter fork engaged with the starter of the starter.
  • the carcass 1 is closed at its second axial end opposite its bottom 1a by the cover 6.
  • the support block 6 comprises a cylindrical annular skirt, which allows its centering and attachment to the second open end of the carcass 1, and a transverse bottom which axially closes the contactor.
  • the support is made of plastic.
  • the terminals are substantially diametrically opposed on the bottom of the cover 6, on either side of the axis of axial symmetry of the contactor.
  • the terminals each comprise a contact head arranged inside the contactor, against the transverse bottom of the support block 6, and a connection pad partially threaded and which extends axially through the transverse bottom so as to open at the bottom. outside the contactor.
  • the first terminal is intended to be connected to the positive terminal (not shown) of a battery of the vehicle via a switch usually actuated by the ignition key or by any other means.
  • the second terminal is provided to receive a power cable (not shown) of the starter motor.
  • the support block 6 is fixed, by sealed crimping, to the second end of the carcass 1.
  • this carcass 1 has at its second end, constituted by the free end of its tubular portion 1b, a transverse shoulder 1c for support fixed core 2, a cylindrical centering portion of the fixed core 2 and a cylindrical portion 1d of small thickness, said crimping portion, for fixing by crimping the cover 6. More precisely the end of the portion 1d is folded into 6a ( Figure 1) inwardly in contact with an outer portion of frustoconical shape of the cover 6 for clamping the fixed core 2 between the shoulder 1c and the free end of the cover 6.
  • the portion 1d of axial orientation s extends axially, in the opposite direction to the bottom 1a, beyond the shoulder 1c.
  • a movable contact 5, consisting of a plate, is capable of being displaced axially inside the space delimited by the annular wall and the bottom of the cover 6, between a rear rest position in which it bears against the fixed core 2 and an active front position in which the movable contact 5 bears simultaneously against the terminal heads so as to establish between these two terminals an electrical connection which allows powering the starter motor with electrical power from the vehicle's accumulator battery.
  • the axial displacement of the movable contact 5 is controlled by a control rod, which is guided axially, and whose displacements are controlled by the movable core 3.
  • the movable contact 5 is slidably mounted on the control rod.
  • the control rod causes the movable contact from its rest position to its active position by means of a contact spring which is supported on one side against a shoulder of the control rod and on the other side against the rear transverse face of the movable contact 5.
  • a return spring makes it possible to return the control rod and the movable contact 5 to the rest position.
  • the return spring is supported at the bottom of a cylindrical housing arranged at the center of the transverse bottom of the cover 6 and it axially urges a metal washer (not visible) which bears against a second shoulder of the control rod and against the front transverse face of the movable contact, which also cooperates with the terminals.
  • the movable contact in one embodiment comes into contact with the fixed core 2 advantageously provided with protuberances for this purpose.
  • the contactor is here electronically and comprises a printed circuit board carrying electronic components and which extends in a transverse plane and axially between the fixed core 2 and a transverse wall belonging to a sealing partition.
  • the sealing partition is made by molding in plastic material thus allowing for force insertion into the cover 6 advantageously made of the same material. The seal is obtained by the deformation of the material.
  • control rod which connects the movable magnetic core 3 to the movable contact 5, passes axially through a tubular axial shaft of the sealing wall.
  • the axial shaft is stepped in diameter and has a front and rear section as described in the application FR 99 09977.
  • the rear axial annular section is intended to be received inside the bore of the fixed core with which it cooperates sealingly.
  • a metal connection can be inserted into the bulkhead.
  • the metal connection provides electrical contact between the fixed core 2 and the movable contact 5 when in the rest position.
  • This connection comprises a tab which protrudes axially towards the front of the partition and which is folded radially so as to extend along the transverse front face of the partition to ensure electrical contact with the moving contact 5 when the latter is in the rest position.
  • This tongue is integral with a washer-shaped base axially traversed by the rear axial annular section of the barrel of the partition. The base ensures electrical contact with the fixed core 2.
  • the barrel has a hole for the passage of the tongue. This hole is formed in the shoulder formed by the change of diameter between the rear and front sections of the shaft of the partition.
  • the mobile contact in the rest position is therefore according to the embodiments in contact with either the fixed core, in particular when there is no electronic card inside the contactor, or with a sealing partition. directly or indirectly via a part in electrical contact with the fixed core.
  • the thicknesses of the bottom 1a and the tubular portion 1b of the carcass 1 are determined according to the needs of the passage of the magnetic flux. In practice to avoid too much current consumption and too much copper volume at the winding 4, it is necessary not to saturate too much the magnetic circuit, so to have a sufficiently large magnetic flux passage section.
  • the bottom 1a thus has a relatively large thickness of the order of 3 to 6 mm.
  • the thickness of the tubular portion 1b is lower because the passage section of the magnetic flux is distributed over a larger circumference. This thickness is of the order of 2 to 4 mm. These thicknesses correspond to a manufacture of the carcass by deep drawing of a sheet.
  • the crimping portion 1d usually has a thickness of 0.4 mm to 1 mm; the tubular portion 1b internally having three different diameters for including formation of the shoulder 1c in favor of a change in diameter.
  • the carcass 1 is made in a first step by stamping, then in a second operation is the object of machining resumption operations and finally undergoes in a third step a surface treatment to provide protection against corrosion and give a good appearance to this carcass visible from the outside, especially when the starter is mounted on a vehicle.
  • the machining resumption operations are necessary because, on the one hand, it is necessary to make a length of the carcass 1, and on the other hand, to achieve internal diameters of the tubular portion 1b for formation of the shoulder 1c and the crimping portion 1d.
  • the surface treatment must be a good conductor of electricity because the external face of the bottom 1a (the rear face) serves to return the earth of the winding 4, which carries out a function of holding the moving contact after closing thereof when the electric motor of the starter rotates, and in the case of an electronically controlled contactor back to earth of the electronic circuit.
  • the bottom 1a is used for fixing the contactor on the housing of the starter.
  • a contactor provided with a carcass made of magnetic material of the type indicated above is characterized in that the carcass is made in three pieces, namely a first piece of transverse orientation, called the bottom, constituting the perforated bottom, a an axially oriented outer tube having the crimping portion and an axially oriented inner tube housed inside the outer tube and in that the outer tube is fixed to the bottom and extends in the opposite direction to the bottom, projecting axially relative to the inner tube having the shoulder.
  • the inner tube is in contact with the bottom and with the outer tube.
  • the thickness of the bottom can easily be increased.
  • the outer tube advantageously undergoes in advance the surface treatment operation.
  • the inner tube is protected and does not need surface treatment as it is surrounded by the longer outer tube.
  • This inner tube is housed fixing in the inner tube advantageously by fitting.
  • the bottom does not need to undergo an aesthetic surface treatment because it is less visible than the external tube made aesthetic, including color and appearance point of view, by its surface treatment also suitable for corrosion resistance.
  • This surface treatment of the outer tube does not have to take into account a good conduction of the electricity produced by the protected inner tube, so that there is a greater number of choices as regards the surface treatment of the outer tube.
  • the bottom is in contact with the starter housing, carrying the electric motor and the contactor, it is possible to do without a surface treatment of the bottom because the risk of corrosion is low because the starter housing is in aluminum alloy.
  • the starter is subjected to a more aggressive environment from the point of view of corrosion and / or protection is required we choose the nature of the treatment that is best without aesthetic concern.
  • the thickness of the inner tube increased by the thickness of the outer tube is chosen to correspond to the thickness of the tubular portion of FIG. 2 and the thickness of the outer tube corresponds to the thickness of the crimping portion of FIG. Figure 2.
  • This outer tube of smaller thickness than the inner tube, is cut to the desired length to have the desired length for the crimping portion.
  • This arrangement facilitates the standardization of the inner tube because the contactor can be electronically or not, which affects the length of the cover and the crimping portion.
  • the outer tube is therefore a piece of adaptation to this variation in length and exceeds more or less of the inner tube to vary the length of the crimping portion according to the applications, which reduces the number of reference parts to store .
  • the inner tube strengthens the passage section of the magnetic flux and conducts electricity.
  • the means of production can be brought together in the same geographical location, thereby reducing the additional costs of transport and production management.
  • the outer tube covers at least part of the outer periphery of the bottom, which may not be visible and serves as a centralizer to the outer tube.
  • This arrangement facilitates the attachment of the outer tube with the bottom because it allows a prior centering of these parts.
  • the first piece constituting the bottom consists of an embodiment in a simple washer.
  • the bottom is rectangular, square or polygonal. This is made possible because one can easily give a complementary shape to the relevant end of the outer tube or even to the entire outer tube.
  • the inner tube easily having a shape complementary to that of the outer tube, it follows that the section of the tubes can be circular, rectangular, square, polygonal or other.
  • Fixing the outer tube with its bottom is advantageously carried out inside the outer tube and thus the carcass to protect this fixation and for aesthetic reasons.
  • the bottom and the outer tube are assembled, that is to say fixed to each other, by indirect heat supply, in particular by laser or electron beam welding, which allows a very high degree of heating. located not affecting the outer periphery of the outer tube when this welding is performed inside the carcass. In addition no metal supply is necessary and we obtain a solid fixation, waterproof with good continuity of the magnetic circuit and without protrusion of the weld bead.

  • This inner tube 14 has the shoulder 14 'for the fixed core 2 and is here in contact with the bottom 12 and with the outer tube 13 of smaller thickness than the inner tube 14. The thickness of the bottom 12 and therefore the first part is greater than that of the tubes 13,14.

  • the outer tube 13 is set to length to have the same axial length as that of the carcass of Figures 1, 2 and therefore to have the same axial position for the free ends of the crimping portions 1d, 13 '.
  • This outer tube 13 is intended, via the inner periphery of its cylindrical crimping portion 13 ', to serve as centering the fixed core. This arrangement simplifies the carcass, which thus has only two diameters internally and does not involve machining operations. additional. The length of the portion 13 'is greater than the portion 1b. Of course the outer diameter of the fixed core is increased in this case.

  • This treatment in terms of quality and cost are much greater than those of the carcass of FIG. 2 because this treatment does not have to be a good conductor of electricity.
