Definitions
- the present invention relates to the method of mounting a movable contact on a control rod, which comprises an electromagnetic contactor for a power circuit, in particular for an electric motor of an internal combustion engine starter, in particular of a motor vehicle .
- the present invention also relates to an electromagnetic contactor, in particular for an electric motor of an internal combustion engine starter, comprising such an assembly.
- an electromagnetic contactor for a power circuit comprises a moving element comprising a movable contact mounted on a control rod.
- the movable contact is intended to come into contact with fixed electrical contact terminals, arranged in a contact chamber at the front of the contactor.
- This contactor is for example used to control the actuation of an electric motor of an internal combustion engine starter.
- FIG. 1 which is a partial view in axial section, illustrates such a contactor 10 of the state of the art for an electric motor of an internal combustion engine starter, provided with a mobile core 16, a fixed core 24, both of ferromagnetic material, and a metal housing 12, also called tank, wherein is arranged at least one coil 14 mounted on an insulating annular support (not referenced). The support is engaged on an annular bearing (not referenced) of the fixed core 24. This support and the rear end of the tank 12 are centrally provided with a passage for the movable core 16.
- This coil 14, when activated electrically following for example to actuation of the ignition key, controls the axial displacement of the movable core 16 towards the fixed core 24.
- One end of the movable core 16 is connected to a pivoting lever (not shown) which acts for example on the launcher of the starter as described in the document FR A 2 795 884 and it is for this reason that we see partially in 50 in Figure 1 the spring teeth against teeth and 51 the connecting rod to the pivoting lever.
- the other front end 18 of the movable core 16 is intended to act on a control rod 20 by pushing through a central hole 22 of the fixed core 24 in which the rear portion 26 of the rod 20 is slidably mounted.
- the rod 51 and the spring 50 are mounted inside a cavity closed by the front end 18, in the form of a washer, of the movable core 16, which controls the axial displacements of the control rod 20, electrically
- This rod is thus pushed by its rear end 26 and carries at its opposite end before 28 a movable contact 30, slidably mounted on the control rod 20.
- the movable contact 30 is substantially plate-shaped electrically conductive material. This contact 30 extends transversely to cooperate with two heads 32 and 34 of electrical terminals 36 and 38 of an electrical power circuit and establish between them an electrical contact by its front face 29.
- the two terminals 36 and 38 are fixed and are carried by a front cover 40 of electrically insulating material, which is fixed by crimping in a front portion of the housing 12.
- the cover 40 defines a contact chamber for the heads 32, 34 and for the movable contact 30.
- This cover 24 serves also to the fixing of the fixed core 24, axially wedged between a shoulder of the cover 20 and the fixed core 24 having axial projections engaging in notches of the fixed core 24 for locking in rotation and angular indexing of the cover 40.
- One of the terminals 36, 38 is intended to be connected to the positive terminal of the battery, while the other terminal is intended to be connected to the electric motor of the starter as described for example in the document FR A 2 79 5,884 above.
- the rod 20 carries an axial retaining spring 42 arranged between a rear axial shoulder 44 of the rod 20 and a rear face 31 of the movable contact 30.
- the spring 42 is provided to maintain the movable contact 30 bearing forwards on front axial stop means 46 when the movable contact 30 is not in contact with the heads 32, 32.
- These means 46 are constituted by a thrust washer immobilized axially by a claw washer, which is elastic and consists of a Belleville washer having at its inner periphery legs adapted to anchor in the front part of the rod 20.
- the contactor 10 comprises a return spring 48 arranged between the front cover 40 and the control rod 20 to recall the latter, and therefore the movable contact 30, back.
- This spring 48 is supported on the claw washer and on the cover 40.
- the return spring 48 also called the cutoff spring, has a lower stiffness of the holding spring 42, also called contact pressure spring, which makes it possible to a last phase to the movable core 16 to come into contact with the fixed core 24 and the rod 20 to move after coming into contact with the movable contact 30 with the heads 32, 34. In this last phase the spring 42 is compressed and the movable contact 30 occupies finally a retracted active position.
- the coil 14 when energized, the coil 14 creates a magnetic field, which allows the axially forward drive of the movable core 16, which then moves the control rod 20 and the movable contact 30, the latter being brought in contact with the heads 32, 34 to make an electrical contact between the terminals 36,38 and electrically power the electric motor of the starter.
- the movable contact 30 is thus slidably mounted on the rod 20 between an advanced rest position and an active retracted position.
- the spring 42 axially urges the movable contact 30 towards its rest position in which it is in contact with the abutment means 46 beforehand. In its active position, the movable contact is in contact with the heads 32, 34 and the spring 42 is compressed. so that a clearance exists between the contact 30 and the stop means 46 ( Figure 1).
- the arrangement of the contact 30 on the rod 20 is quite complex and comprises a number of parts that must be assembled.
- This arrangement comprises in FIG. 1 six pieces, namely the control rod 20 with a rear axial shoulder 44, the holding spring 42, the movable contact 30, the stop abutment means 46 comprising the thrust washer and the claw washer and finally the return spring 48.
- the means for fixing the abutment means 46 on the rod 20 have the disadvantage of creating particles of insulating material that result from the force fitting of the claw fastener washer. These insulating particles may affect the contact between the heads 32, 34 and the movable contact if they are placed between these elements.
- No. 2,741,996 consists in making grooves in the control rod and in radially crimping the movable contact to form pins which are slidably received in the grooves delimited at the front by an abutment surface for the moving contact. Such a solution is satisfactory because it reduces the number of parts, however, when crimping cracks may appear.
- the present invention proposes to create a bayonet type assembly to mount the movable contact on the control rod.
- a mobile electromagnetic contactor power unit of the type comprising a movable contact carried by a control rod
- bayonet type assembly means intervene between the movable contact and the control rod for mounting the movable contact on the control rod and in that these assembly means of the bayonet type are configured to achieve a locking rotation of the movable contact on its control rod.
- an electromagnetic contactor in particular for an electric motor of an internal combustion engine starter, of the above-mentioned type comprising a moving element is characterized in that it comprises a moving element according to the invention.
- the movable contact through its hole or central orifice, forming a passage, is placed on the control rod and is rotated to come into contact with its front face with at least one stop integral with the rod. ordered.
- the invention compared to the solution of Figure 1 is removed two pieces namely the thrust washer and the claw washer so that the solution is simple, economical and reduces the number of parts to be stored.
- the assembly is faster and without risk, on the one hand, pollution of the contact chamber by particles torn off the control rod during assembly of the claw washer due to the removal of this washer claws and on the other hand, forgetting the mounting of the thrust washer and / or the claw washer.
- the reliability of the contactor is also improved by eliminating the resilient spring washer subjected to fatigue during operation of the contactor.
- the lifespan of the moving equipment is thus increased, while reducing the number of parts.
- the reliability of the contactor is also improved because of the absence of crimping at the mobile contact, which in certain cases reveals failure primers and / or cracks. .
- the solution according to the invention makes it possible to increase the life of the contactor. It is therefore possible to stop and restart the internal combustion engine a greater number of times. Thus in the case of an application to a motor vehicle can stop the internal combustion engine at a red light and restart it to reduce fuel consumption.
- the mounting of the movable contact on its control rod is performed without special precautions, is robust and takes advantage of the holding spring which urges the movable contact towards at least one rigid abutment integral with the control rod.
- the stop is in one piece with the control rod.

- the movable contact 30 is mounted on its control rod 20 by means of assembly means bayonet type.
- the axial length of the mounting section 142 of the holding spring 42 is reduced, as is the axial length of the first section 128 for mounting the return spring 48 to maintain the axial length of the rod 20.
- the reduction in the axial length of the first section 128 is made possible by the suppression of the claw washer and the thrust washer of FIG. 1. This first section 128 is therefore arranged with respect to that of FIG. less mechanically stressed.
- the third section 130 is cylindrical in shape and has a smaller external diameter than the fourth section 142, the chamfer 131 being a connecting chamfer between the sections 130 and 142.
