- the invention aims to improve the degree of resistance of such a component to the intrusion of solid and liquid bodies.
- the present invention provides an electronic component, in particular a sensor, in particular for detecting particulate matter, comprising: an electronic member, a box in which the electronic member is placed, this box comprising: o at least one functional opening , o at least one protective visor, arranged on the housing to protect the electronic member from the intrusion of material, in particular fluids or solids, into the housing, which could pass into the functional opening.
- the visor thus makes it possible at least partially to screen the liquid and solid bodies which would otherwise penetrate into the case through the opening, transported by air or by flow on the case.
- Embodiments propose that: the visor partially surrounds the periphery of the opening,
- the visor surrounds less than half of the periphery of the opening
- the opening has a polygonal shape and the visor surrounds at least one side of said opening, the visor surrounds the opening in an arc,
- the visor surrounds the opening on a main side of said opening, in particular rectilinearly, and partially surrounds the opening on two lateral sides of said opening, in particular in an arc of a circle,
- the visor extends over the periphery of the opening, in particular directly over said periphery, in particular over part of said periphery,
- the visor extends substantially perpendicular to the opening
- the visor extends at an angle to the opening
- the visor has a drainage channel
- the drainage channel surrounds the opening on the main side in a straight line and partially surrounds the opening on the lateral sides in an arc
- the drainage channel is open at the ends of the visor
- the visor comprises an internal face opposite the opening and an external face opposite the internal face
- the drainage channel is formed on the external face
- the housing comprises at least one wall which delimits the interior of the exterior of said housing, and the visor extends projecting from said wall,
- the visor extends in line with the wall
- the wall comprises a connection tube whose free end constitutes the opening, the visor extends in the extension of the connection tube, in particular over a part of the periphery of the tube,
- the case has two half-shells, including a base and a cover,
- the visor is made in one piece with the cover
- the visor is made of material with the cover
- the visor is rigid
- the visor is flexible
- the opening allows fluid to pass inside the housing
- the opening is an air intake
- the opening is an air outlet
- the opening makes it possible to connect the electronic organ electrically
- the opening is an electronic connector
- the housing includes at least three openings, including at least one air inlet, one air outlet and one electronic connector, at least one protective visor being arranged on the housing to protect the electronic member from material intrusion, in particular fluids or solids in the housing that could pass through at least one of the three functional openings.
- the invention also relates to a motor vehicle comprising or on which is disposed an electronic component as previously described.
- the visor is substantially above the functional opening when the electronic component is in the operational position in the vehicle.
- the visor thus shields against bodies descending towards the opening, protecting it in particular against gravity flows.
- FIG. 1 illustrates a perspective view of a particulate matter detection sensor
- FIG. 2 illustrates an enlarged view of an air outlet from the sensor
- FIG. 3 illustrates a front view of said air outlet
- FIG. 4 illustrates a view of an electronic connector of the sensor
- FIG. 5 illustrates a front view of said electronic connector.
- the particulate matter detection sensor 1 according to the present invention is suitable for use in a motor vehicle.
- the senor 1 comprises an electronic member (not shown) and a housing 2 in which the electronic member is placed.
- the housing 2 comprises in particular a chamber for measuring the particulate matter (not shown).
- the housing 2 comprises a first and a second functional opening 3a; 3b.
- the first opening 3a constitutes an electronic connector 4 for said sensor 1 and thus makes it possible to electrically connect the electronic member.
- the second opening 3b constitutes an air outlet 5 for the particulate matter detection sensor 1.
- a first and a second protective visor 6a; 6b respectively partially surround the electronic connector 4 and the air outlet 5.
- the first and second visors 6a; 6b are each arranged on the housing 2 to protect the electronic member from material intrusions, in particular fluids or solids, into the housing 2, which could pass through the air outlet 5 or the electronic connector 4.
- each of the visors 6a; 6b thus forms a prominence which projects in relief from each of the openings 3a; 3b, thus forming a projection on each of the openings 6a; 6b.
- each of the visors 6a; 6b comprises an internal face opposite the opening 3a; 3b corresponding and an outer face opposite the inner face.
- the visors 6a; 6b thus make it possible at least partially to screen liquid and solid bodies which would otherwise penetrate into the housing 2 through the openings 3a; 3b. These bodies are for example transported by air or by flow over the housing 2.
- a wall 7 delimits the interior of the exterior of the housing 2, and each of the first and second visors 6a; 6b extend projecting from said wall 7.
- the wall 7 comprises a connection pipe 8, the free end of which constitutes a third functional opening 3c.
- said third opening 3c constitutes the air inlet of the particulate matter detection sensor 1.
- the connection tube 8 is arranged to be able to be placed in fluid communication with, for example, an air supply hose (not shown).
- the second and third apertures 3b; 3c thus make it possible to pass a fluid inside the sensor 1, in particular inside the housing 2, in particular in the chamber for measuring the particulate matter (not shown).
- the second and third openings 3b; 3c and the housing 2 thus define a fluid path for the air flowing in the particulate matter sensor 1.
- a third visor extends in the extension of the connection tubing 8, in particular over a part of the periphery of the tubing 8.
- the third visor thus protects the third air inlet 3c from intrusions of liquid and solid bodies, without impacting the compatibility of said tubing 8 with an air supply hose.
- the visors 6a; 6b are rigid, but a flexible variant of the visors 6a could also be provided; 6b.
- the housing 2 comprises two half-shells, including a base 9 and a cover 10.
- the base receives the elements of the internal electronic organ.
- the cover 10 fits onto the base 9 by complementarity of form, here by clipping, thus making it possible to at least partially close the housing 2. According to an embodiment not shown, the cover 10 fits on the base 9 to the screw means.
- the base 9 comprises a bulge 1 1 towards the outside of the latter. This bulge 1 1 to accommodate a screw for fixing the housing 2 on the vehicle. Several bulges may be provided distributed over the base 9 of the housing 2.
- the first and second visors 6a; 6b are formed in one piece with the cover 10.
- the first and second visors 6a; 6b can thus be advantageously formed during a single manufacturing operation, in particular molding, of the cover 10 and the visors 6a; 6b.
- the air outlet 5 and the electronic connector 4 each have a substantially polygonal shape.
- the first visor 6a surrounds less than half of the periphery of the electronic connector 4, as can be seen in FIG. 5.
- the first visor 6a surrounds the electronic connector 4 on a main side 4A of said electronic connector 4, in a straight line.
- the first visor 6a partially surrounds the electronic connector 4 on two lateral sides 4B; 4C of said connector 4, here in an arc.
- the first visor 6a extends away from the periphery of the electronic connector 4, as can be seen in FIG. 5.
- the first visor 6a has a drainage channel 12 formed on the outer face of said visor 6a.
- the drainage channel is, as visible in FIG. 4, U-shaped and comprises a bottom 12f, in particular rounded, and two side walls 12p.
- the side walls 12p extend substantially inclined relative to the first opening 3a.
- the side walls make it possible to concentrate the flows towards the bottom of the drainage channel 12.
- the drainage channel 12 is open at the ends of the visor 6a and is thus configured to allow no water retention.
- Each of the internal and external faces of said visor 6a is thus at least partially concave.
- the first visor 6a thus deflects the flows from the electronic connector 4, thanks to the drainage channel 12.
- the second visor 6b substantially surrounds half of the periphery of the air outlet 5.
- the second visor 6b surrounds the air outlet 5 on a main side 5A of the air outlet 5, in a straight line.
- the second visor 6b also partially surrounds the air outlet 5 on two lateral sides 5B; 5C of said air outlet 5, here in an arc.
- the second visor 6b extends directly over a portion of the periphery of the air outlet 5, unlike the visor 6a which extends at a distance from the periphery of the electronic connector 4.
- the second visor 6b extends substantially perpendicular to said air outlet 5.
- the second visor 6b is concave on its internal face and convex on its external face, like this and visible in FIG. 2.
- the particulate matter sensor 1 according to the present invention may, for example, be placed on or integrated in a motor vehicle.
- first and second visors 6a; 6b are arranged substantially above the electronic connector 4 and the air outlet 5 when the sensor 1 of particulate matter is in the operational position in the vehicle.
- the visors 6a; 6b thus shield against the bodies descending towards the openings 3a; 3b, protecting them in particular against gravity flows.
