Definitions
- the present invention relates to an electrical switch with rubbing contact, in particular for control modules under the steering wheel or motorized drive systems wiper blades.
- electrical switches with rubbing or sliding contact are widely used.
- a command such as for example the lighting of the vehicle lights or the windshield wiper controls.
- FR 2 933 530 in the name of the Applicant.
- These rubbing contacts are very high since it is necessary to ensure the proper functioning of these rubbing contacts throughout the life of the vehicle, that is to say up to 10 to 15 years, under difficult operating conditions. It may be for example high current friction contacts (for example a few Amperes) that are used today in low cost vehicles to directly control the wiper motor or headlights, or friction contacts for low current (for example a few mA) which will control for example a power relay connected to the wiper motor or headlights. Indeed, these rubbing contacts are subject to significant temperature variations ranging from -40 ° C to + 120 ° C. Dust may be deposited on the conductive track of the PCB and prevent operation, i.e., establishing the electrical contact.
- the vehicle can be parked in any place, it can be subjected to moisture or even salty moisture, which can cause oxidation problems.
- the oxide layer which is electrically insulating prevents the establishment of an electrical contact.
- the contact resistance can vary and moreover, there can also be metal part abrasion problems which can, in the long run and by accumulation cause false electrical contacts and thus cause a malfunction of the control module under steering wheel.
- friction contacts for high current there is also added problems of formation of an electric arc that can alter the electrical contact surfaces.
- This lubricant has been and is still the subject of much research, especially at the request of manufacturers of contacting contact circuits or manufacturers of control modules under steering wheel etc. To testify to this research activity, we can cite a number of documents.
- FR2 939 973 discloses a method of manufacturing a connector element comprising a substrate on which a layer of gold is deposited.
- the connector described is a male-female connector whose electrical contact comprises a layer of gold treated by ion bombardment.
- this document does not describe a rubbing contact as known in the control modules under the steering wheel and the problematic associated therewith, in particular the problems due to displacements of the electrical contact rubbing on the conductive track. Indeed, a male-female connector is not subjected to the same mechanical stresses of displacement as a rubbing contact.
- the present invention therefore proposes an electric switch having an improved contact with respect to the state of the art.
- the subject of the present invention is an electrical switch with a frictional contact comprising on the one hand at least one fixed contact and on the other hand at least one movable rubbing contact along a predefined path and having a contact surface intended to rub on said at least one fixed contact, characterized in that at least said contact surface is treated by ion bombardment by means of an ion beam, and in that the fixed and moving contacts are exposed.
- the electrical switch is devoid of lubricant, that is to say without contact grease, which is a consequent improvement of the known electrical switches and has a considerable advantage in terms of cost and installation time. switches without affecting the reliability of operation in terms of operating cycles, wear, contact resistance, robustness against contamination or oxidation.
- the Applicant has thus overcome a prejudice largely rooted in the technological field of electrical switches with moving contact rubbing.
- the electrical switch may furthermore have one or more of the following characteristics, taken alone or in combination: said at least one fixed contact is free of contact grease; all of the fixed and moving contacts are treated by ion bombardment by means of an ion beam, at least at the level of the surfaces that can come into electrical contact; the moving rubbing contact is made of steel, copper, stainless steel, bronze, brass, aluminum or an aluminum alloy; said contact surface of the moving friction contact comprises a nickel plating on the substrate forming the rubbing moving contact and a plating of a noble metal on the nickel plating; said contact surface of the rubbing moving contact comprises a plating of a noble metal on the substrate forming the rubbing moving contact; the thickness of the noble metal plating is between 0.25 ⁇ and ⁇ ; said contact surface for rubbing on said at least one fixed contact has a curved surface having a first radius of curvature of between 0.5mm and 5mm in the direction of movement of the moving friction contact and a second radius
- the invention also relates to a control module under steering wheel for a motor vehicle, characterized in that it comprises an electrical switch as defined above, the movable rubbing contact is connected to a control lever, including control of the headlights or windshield wipers.
- FIGS. 1a and 1b are top views of an electrical switch 2a and 2b are end and end face views of a movable rubbing contact
- FIG. 2c is a sectional view of one end of FIG. 2a
- FIG. Figure 3 is a top view of a fixed contact holder of the electrical switch rubbing contact.
- FIGS. 1a, 1b and 3 illustrate an exemplary embodiment of an electrical contact switch 1.
- Such an electrical switch 1 can for example be integrated in a control module under a steering wheel for a motor vehicle, in particular for performing the electrical switching of safety functions such as, for example, the control of the lights, wipers, etc., or in a motorized soot-ice brush drive system for controlling the movement of the brooms back and forth.
- the invention can be transposed for a strong current electrical switch, that is to say greater than 1A, which is distinguished from a low current switch in particular by the increased cross section of the conductors to be able to pass this strong current.
- This electrical switch 1 comprises on the one hand at least one, in the figure the several fixed contacts 9 arranged on a support 7.
- the support 7 is for example a printed circuit board and the fixed contacts 9 are contact pads.
- the fixed contacts 9 are arranged in a circle on the support
- the support 7 comprises eight fixed contacts 9 in the form of arcuate bands.
- the fixed contacts 9 thus define four different switching states of the electrical switch 1, since for reasons of operational safety, the fixed contacts 9 are doubled in this example.
- an additional fixed contact 14 in the form of a ring, and connected to a power supply or ground.
- This additional fixed contact 14 is for example arranged concentrically to the circle formed by the fixed contacts 9.
- the electrical switch 1 comprises at least one moving rubbing contact 3 that can evolve along a predefined path, in this case an arcuate trajectory that can bring it into contact with one or more of the fixed contacts 9.
- This trajectory is at least partially parallel to the plane defined by the support 7, that is to say the printed circuit board.
- it is a rotary switch and the moving frictional contact 3 can thus perform a rotational movement.
- the moving rubbing contact can be made in the form of a carriage moving along a path in a straight line to be able to come into contact with fixed contacts arranged in line.
- the friction contact 3 mobile is for example connected to a control lever, including control of the headlights or wipers.
- a control lever including control of the headlights or wipers.
- the switch 1 can thus establish an electrical contact for one or more predefined positions of the moving rubbing contact 3 with at least one corresponding fixed contact 9 carried by the support 7.
- the movable rubbing contact 3 is in the form of a fork having at least two, here three legs 11, 12, 13 preferably flexible, mounted on a movable base.
- the mobile base further comprises means for attachment to a control element of the device (not shown).
- the branches 11, 12 are able to establish two simultaneous electrical contacts with two corresponding fixed contacts 9 and are doubled to better ensure operational safety.
- the branch 13 is in rubbing contact with the additional fixed contact 14.
- the friction contact 3 comprises on each leg 11, 12, 13 a curved end 5 biased towards said support 7.
- the curved portion of the curved end 5 frictionally engages the corresponding fixed contact 9, for make an electrical contact.
- the end 5 of each branch thus forms a contact surface 10 intended to rub on said at least one fixed contact 9.
- At least this portion of the end 5 of each branch intended to rub on a fixed contact 9 is treated by ion bombardment by means of an ion beam.
- This treatment by ion bombardment gives this treated portion a better surface state reducing friction.
- this better surface state prevents contamination of the moving contact rubbing, for example by silicone.
- this treatment prevents the risk of oxidation which keeps the contact resistance at a permissible level throughout the life of the switch.
- the fixed contacts 9 and mobile 3 are exposed, that is to say free of a lubricant, such as contact grease.
- both the fixed contacts 9 and mobile rubbing 3 are treated by ion bombardment through an ion beam. It may be a local treatment only at the surfaces that come in contact, or one can also consider a treatment of fixed contact and moving rubbing as a whole.
- the movable rubbing contact 3 can be made of steel, copper, stainless steel, bronze, brass, aluminum or an aluminum alloy.
- ion bombardment makes it possible to reduce or even eliminate the formation of an insulating oxide layer at the moving contact, so that a nickel plating is no longer necessary.
- the substrate of the rubbing mobile contact is subjected as a whole to ion bombardment by an ion beam.
- the contact surface 10 of the moving contact 3 comprises a nickel plating on the substrate forming the frictional contact 3 and a plating of a noble metal, such as gold or silver, on the nickel plating.
- a noble metal such as gold or silver
- said contact surface 10 of the frictional contact 3 comprises only a plating of a noble metal, such as gold or silver, on the substrate forming the rubbing moving contact.
- a noble metal such as gold or silver
- This variant also has the advantage of eliminating the nickel plating which is necessary in the known art to be able to adhere the noble metal to the substrate, in particular copper or brass. So, in addition to the removal of contact grease, we can get rid of nickel which also makes the switch less polluting for the environment, both during its manufacture and end of life. In addition, the removal of the nickel plating also eliminates a step in the manufacture of the switch and reduces the cost of the electrical switch.
- the treatment by ion bombardment does not only have the effect of improving the surface state of the electrical contact surface, but also of allowing the adhesion of the noble metal to the substrate which is in a non-noble metal, this without going through a plating like nickel for example.
- the thickness of the noble metal plating (gold and silver) is between 0.25 ⁇ and ⁇ , which is much lower than the thicknesses known until now of 2 to 3 ⁇ .
- the material cost of noble metals which has increased significantly in recent times, the significant decrease in the thickness of noble metal and therefore the amount of noble metal to be applied also allows a significant decrease in the cost price of the switch. electric.
- no plating is applied to the electrical contact surface 10. This end is therefore only treated by bombardment with an ion beam. This further reduces the cost of manufacturing the electrical switch while ensuring a good operation over the life of the electrical switch, all without contact grease.
- the end 5 of the moving friction contacts is curved or curved.
- the radius of curvature of the first curved portion of the curved end 5 is between 0.5 mm and 5 mm ( Figure 2c) in the direction of movement of the moving friction contact.
- the radius of curvature r of the second curved portion of the curved end 5 is between 0.5 and 2 mm ( Figure 2b) in the direction perpendicular to the displacement of the moving friction contact. It is therefore understood that it is possible to produce an electrical switch with a sliding contact without contact lubricant, or even without nickel plating and even without any noble metal. which allows a competitive cost price, a better environmental compatibility ensuring an exemplary safety of operation.
