Description

La présente invention concerne une pièce d'équipement de véhicule automobile, selon le préambule de la revendication 1.The present invention relates to a piece of motor vehicle equipment, according to the preamble of claim 1.

On connaît de FR-A-2 795 670 une pièce d'équipement comprenant un corps et un cheminement électrique surmoulé sur le corps. Un connecteur électrique raccordé au cheminement est encliqueté sur la pièce par l'intermédiaire de pattes d'encliquetage, afin de raccorder électriquement le cheminement électrique à un autre organe électrique sur le véhicule.We know FR-A-2,795,670 a piece of equipment comprising a body and an electrical path overmolded on the body. An electrical connector connected to the path is snapped onto the part by means of locking tabs, in order to electrically connect the electrical path to another electrical component on the vehicle.

Une telle pièce ne donne pas entière satisfaction. En effet, les moyens de maintien du connecteur sont constitués, d'une part, par les pattes d'encliquetage et d'autre part, par des butées intégrées au connecteur. Le raccordement électrique du connecteur sur la piste de contact du cheminement électrique est donc simple à effectuer, mais peu robuste. En outre, la fiabilité en milieu humide du raccordement électrique n'est pas assurée. US 5,554,042 décrit une pièce selon le préambule de la revendication 1.Such a piece does not give complete satisfaction. Indeed, the connector holding means are constituted, on the one hand, by the latching lugs and on the other hand, by stops incorporated in the connector. The electrical connection of the connector on the contact track of the electrical path is therefore simple to perform, but not robust. In addition, the reliability in wet environment of the electrical connection is not assured. US5,554,042 describes a part according to the preamble of claim 1.

Un but de l'invention est d'obtenir une pièce d'équipement munie d'une piste de raccordement à un cheminement électrique solidaire de la pièce, et d'un connecteur électrique maintenu sur la piste, la pièce étant facile à monter, tout en assurant un raccordement électrique fiable, notamment en milieu humide.An object of the invention is to obtain a piece of equipment provided with a connecting track to an electrical path integral with the workpiece, and an electrical connector held on the track, the workpiece being easy to mount, while by ensuring a reliable electrical connection, especially in a humid environment.

A cet effet, l'invention a pour objet une pièce selon la revendication 1.For this purpose, the subject of the invention is a part according to claim 1.

La pièce selon l'invention peut comprendre l'une ou plusieurs des caractéristiques qui font l'objet des revendications 2 à 7.The part according to the invention may comprise one or more of the features which are the subject of claims 2 to 7.

La Figure 1 représente une première pièce 10 d'équipement de véhicule automobile selon l'invention.The Figure 1 represents a first piece 10 of motor vehicle equipment according to the invention.

Comme illustré par la Figure 1, la pièce 10 comprend un corps 12, un cheminement électrique 14 solidaire du corps 12 sur sensiblement toute sa longueur, et un connecteur électrique 16 rapporté sur le corps 12 pour être raccordé électriquement au cheminement électrique 14.As illustrated by Figure 1 , the piece 10 comprises a body 12, an electrical path 14 secured to the body 12 over substantially its entire length, and an electrical connector 16 attached to the body 12 to be electrically connected to the electrical path 14.

La pièce 10 comprend en outre un capot 18 de maintien en position du connecteur 16 sur le corps 12 et, dans cet exemple, et des moyens 20 d'encliquetage du capot 18 sur le corps 12.The part 10 further comprises a cover 18 for holding the connector 16 in position on the body 12 and, in this example, and means 20 for latching the cover 18 on the body 12.

Le corps 12 est par exemple un pare-chocs, un bandeau, une façade de face avant, un absorbeur de chocs, ou une poutre de pare-chocs de véhicule automobile ou encore une pièce rapportée sur les pièces précitées.The body 12 is for example a bumper, a strip, a facade front, a shock absorber, or a bumper beam of a motor vehicle or a patch on the aforementioned parts.

Le corps 12 est fabriqué à base d'une matière isolante électriquement comme par exemple une matière plastique. II présente une surface d'appui 22 du connecteur électrique 16 dirigée vers le haut sur la Figure 1. La surface d'appui 22 est sensiblement plane au voisinage d'une région d'application du connecteur 16 sur la surface 22.The body 12 is made of an electrically insulating material such as a plastic material. It has a bearing surface 22 of the electrical connector 16 directed upwards on the Figure 1 . The bearing surface 22 is substantially flat in the vicinity of an application region of the connector 16 on the surface 22.

Le cheminement électrique 14 est par exemple surmoulé dans le corps 12. Il comporte ainsi une partie (non visible) couverte par le corps 12, et une partie 24 découverte formant trois pistes 26A à 26C conductrices pour le raccordement électrique du cheminement 14 au connecteur 16.The electrical path 14 is for example overmolded in the body 12. It thus comprises a part (not visible) covered by the body 12, and an exposed portion 24 forming three tracks 26A to 26C conductors for the electrical connection of the path 14 to the connector 16 .

Les pistes 26A à 26C sont constituées par trois bandes conductrices s'étendant sensiblement parallèlement les unes aux autres, chacune étant reliée à un chemin de conduction électrique distinct du cheminement 14. Les pistes 26A à 26C sont planes et affleurent la surface d'appui 22.The tracks 26A to 26C are constituted by three conductive strips extending substantially parallel to each other, each being connected to a path of electrical conduction distinct from the path 14. The tracks 26A to 26C are flat and flush with the bearing surface 22 .

En variante, les cheminements électriques sont collés sur toute leur longueur sur la surface 22, ou sont conformés par un dépôt d'encre conductrice (sérigraphie, vaporisation ou procédés similaires...), d'un primaire conducteur, ou d'une peinture conductrice.Alternatively, the electrical paths are glued over their entire length on the surface 22, or are formed by a conductive ink deposit (screen printing, vaporization or similar methods ...), a conductive primer, or a paint conductive.

Le connecteur 16 comprend un boîtier parallélépipédique 28, un joint d'étanchéité 30 rapporté sous le boîtier 28 et visible sur la Figure 2, et des doigts flexibles 32A à 32C de raccordement électrique destinés à être appliqués sur les pistes 26A à 26C.The connector 16 comprises a parallelepipedal housing 28, a seal 30 attached under the housing 28 and visible on the Figure 2 , and flexible fingers 32A to 32C of electrical connection intended to be applied on the tracks 26A to 26C.

Le connecteur 16 comprend en outre un soufflet de liaison 34 flexible, raccordé à un fil électrique 36.The connector 16 further comprises a flexible connecting bellows 34, connected to an electric wire 36.

Comme illustré par les Figures 1 et 2, le boîtier 28 présente une surface supérieure 38 d'application sur le capot 18, une surface inférieure 40 d'application sur la surface d'appui 22, deux surfaces latérales 42 de guidage de l'insertion du connecteur dans le capot 18, une surface distale 44, située à gauche sur la Figure 1, et une surface proximale 46, située à droite sur la Figure 1. Les surfaces 44 et 46 sont perpendiculaires aux surfaces latérales 42 et aux surfaces inférieure et supérieure 40, 38.As illustrated by Figures 1 and 2 , the housing 28 has an upper surface 38 for application on the cover 18, a lower surface 40 for application to the bearing surface 22, two lateral surfaces 42 for guiding the insertion of the connector into the cover 18, a distal surface 44, located to the left on the Figure 1 , and a proximal surface 46, located to the right on the Figure 1 . The surfaces 44 and 46 are perpendicular to the side surfaces 42 and the lower and upper surfaces 40, 38.

Chaque surface latérale 42 délimite une rainure 48 de guidage s'étendant parallèlement à un axe longitudinal d'insertion X-X' du connecteur 16 dans le capot 18.Each lateral surface 42 defines a guiding groove 48 extending parallel to an insertion longitudinal axis X-X 'of the connector 16 in the cover 18.

Chaque rainure 18 débouche transversalement par rapport à l'axe X-X' et axialement à travers les surfaces distale 44 et proximale 46.Each groove 18 emerges transversely with respect to the axis X-X 'and axially through the distal and proximal surfaces 44 and 46.

En référence à la Figure 2, le joint d'étanchéité 30 est inséré dans une gorge ménagée dans la surface inférieure 40. Il présente un contour continu fermé délimitant, sur la surface inférieure 40, une région 50 située à l'intérieur du joint 30, et une région 52 située à l'extérieur du joint 30.With reference to the Figure 2 , the seal 30 is inserted into a groove in the lower surface 40. It has a closed continuous contour delimiting, on the lower surface 40, a region 50 located inside the seal 30, and a region 52 located outside the joint 30.

Le joint 30 fait saillie par rapport à la surface 40 pour séparer de manière étanche la région intérieure 50 de la région extérieure 52 lorsque le connecteur 16 est appliqué contre la surface d'appui 22.The seal 30 protrudes from the surface 40 to seal the inner region 50 from the outer region 52 when the connector 16 is applied against the bearing surface 22.

Les doigts de raccordement flexible 32A à 32C sont disposés à l'intérieur de la région intérieure 50. Ils présentent une forme d'arc de cercle qui fait saillie à l'écart de la surface inférieure 40 vers la surface d'appui 22.The flexible connecting fingers 32A to 32C are disposed within the inner region 50. They have a circular arc shape that protrudes away from the lower surface 40 towards the bearing surface 22.

Dans l'exemple représenté sur la Figure 2, le connecteur 16 comprend trois doigts 30A, 30B, 30C s'étendant parallèlement les uns aux autres et destinés à être appliqués respectivement sur une piste 26A, 26B, 26C respective.In the example shown on the Figure 2 , the connector 16 comprises three fingers 30A, 30B, 30C extending parallel to each other and intended to be respectively applied to a respective track 26A, 26B, 26C.

Le soufflet de raccordement 34 fait saillie axialement à l'écart du boîtier 28 à partir de la surface proximale 46.The connecting bellows 34 protrudes axially away from the housing 28 from the proximal surface 46.

Comme on le verra plus bas, le connecteur 16 est mobile par rapport au capot 18 et au corps 12 entre une position démontée de repos, dans laquelle il est à l'écart du corps 12 et du capot 18, une position d'insertion dans le capot 18 dans laquelle il est appliqué sur la surface d'appui 22 à l'écart du capot 18, et une position montée dans laquelle il est inséré sous le capot 18, entre le capot 18 et la surface 22.As will be seen below, the connector 16 is movable relative to the cover 18 and the body 12 between a disassembled rest position, in which it is away from the body 12 and the cover 18, an insertion position in the cover 18 in which it is applied on the support surface 22 away from the cover 18, and a mounted position in which it is inserted under the cover 18, between the cover 18 and the surface 22.

Dans cet exemple, le capot 18 comprend une paroi supérieure 60, deux flancs latéraux 62 qui font saillie vers la surface d'appui 22 perpendiculairement à la paroi supérieure 60, et des butées 64A, 64B de blocage en position axiale du connecteur 16 par rapport au capot 18.In this example, the cover 18 comprises an upper wall 60, two lateral flanks 62 which project towards the bearing surface 22 perpendicularly to the upper wall 60, and stops 64A, 64B for locking in axial position of the connector 16 relative to at the hood 18.

La paroi supérieure 60 s'étend sensiblement parallèlement à la surface d'appui 22 lorsque le capot 18 est encliqueté dans la surface d'appui 22. La paroi 60 présente une dimension sensiblement égale à celle de la surface supérieure 38 du boîtier 28.The upper wall 60 extends substantially parallel to the bearing surface 22 when the cover 18 is snapped into the bearing surface 22. The wall 60 has a dimension substantially equal to that of the upper surface 38 of the housing 28.

Les flancs latéraux 62A, 62B font saillie vers la surface d'appui 22 à partir des bords latéraux de la paroi supérieure 60. Les flancs 62A, 62B s'étendent parallèlement l'un à l'autre, de part et d'autre de l'axe X-X'. Chaque flanc 62A, 62B comprend une nervure 60 longitudinale s'étendant sensiblement parallèlement à l'axe X-X' sur toute la longueur du flanc 62A, 62. La nervure 66 est de forme sensiblement complémentaire à celle de la rainure 48, pour être introduite dans la rainure 48 lors de l'introduction du connecteur 16 sous le capot 18.The lateral flanks 62A, 62B protrude towards the bearing surface 22 from the lateral edges of the upper wall 60. The flanks 62A, 62B extend parallel to each other, on either side of the the X-X 'axis. Each flank 62A, 62B comprises a longitudinal rib 60 extending substantially parallel to the axis XX 'over the entire length of the flange 62A, 62. The rib 66 is substantially complementary in shape to that of the groove 48, to be introduced into the groove 48 during the introduction of the connector 16 under the hood 18.

Lorsque le capot 18 est encliqueté dans la surface d'appui 22, il délimite avec la surface d'appui 22 un logement 68 de réception du connecteur 16 de forme sensiblement complémentaire au boîtier 28. Le logement 68 débouche à travers une ouverture 70 d'insertion proximale du connecteur 16 sous le capot 18, l'ouverture 70 débouchant perpendiculairement à la surface d'appui 22 et à la paroi supérieure 60.When the cover 18 is snapped into the bearing surface 22, it delimits with the bearing surface 22 a receiving housing 68 of the connector 16 of substantially complementary shape to the housing 28. The housing 68 opens through an opening 70 of proximal insertion of the connector 16 under the cover 18, the opening 70 opening perpendicularly to the bearing surface 22 and to the upper wall 60.

Les butées 64A et 64B sont situées respectivement axialement le long d'un bord proximal et d'un bord distal de la paroi supérieure 60.The abutments 64A and 64B are located respectively axially along a proximal edge and a distal edge of the upper wall 60.

La butée proximale 64A s'étend vers le bas en regard de l'ouverture d'introduction 70. Elle est formée par une patte flexible mobile par rapport à la paroi 60, entre une position supérieure d'introduction du connecteur 16 située hors du logement 68 et une position inférieure de blocage du connecteur 16 dans laquelle elle fait saillie dans le logement 68 au niveau de l'ouverture 70.The proximal abutment 64A extends downwardly opposite the insertion opening 70. It is formed by a flexible tab movable relative to the wall 60, between an upper insertion position of the connector 16 located outside the housing 68 and a lower locking position of the connector 16 in which it projects into the housing 68 at the opening 70.

La butée distale 64B est fixe par rapport à la paroi supérieure 60. Elle fait saillie dans le logement 68.The distal stop 64B is fixed relative to the upper wall 60. It projects into the housing 68.

Les moyens d'encliquetage 20 comprennent des pattes d'encliquetage 72 solidaires du capot 18, et des ouvertures complémentaires 74 correspondantes ménagées dans le corps 12 et débouchant dans la surface d'appui 22.The latching means 20 comprise latching lugs 72 integral with the hood 18 and corresponding complementary openings 74 formed in the body 12 and opening into the bearing surface 22.

Dans l'exemple représenté sur la Figure 1, les moyens d'encliquetage 20 comprennent quatre pattes 72, réparties de part et d'autre du capot 18. Ainsi, deux pattes 72 font saillie vers le bas dans le prolongement du flanc gauche 62A, et deux pattes 72 font saillie vers le bas dans le prolongement du flanc droit 62B. Les pattes 72 sont venues de matière avec le capot 18.In the example shown on the Figure 1 , the latching means 20 comprise four lugs 72, distributed on either side of the cover 18. Thus, two lugs 72 project downwardly in the extension of the left flank 62A, and two lugs 72 project downwards. in the extension of the right flank 62B. The tabs 72 are integral with the cover 18.

Chaque patte 72 solidaire d'un flanc 62A, 62B présente une tête d'encliquetage 74 qui fait saillie vers une patte 72 en regard située sur un flanc 62B, 62A opposé.Each tab 72 secured to a sidewall 62A, 62B has a detent head 74 which projects towards a tab 72 opposite located on an opposite sidewall 62B, 62A.

Les ouvertures 74 sont de forme complémentaire aux pattes 72. Elles s'étendent de part et d'autre des pistes 26A à 26C parallèlement à l'axe X-X'.The openings 74 are of complementary shape to the tabs 72. They extend on either side of the tracks 26A to 26C parallel to the axis X-X '.

Dans cet exemple, le capot 18 est mobile par rapport à la surface d'appui 22 entre une position démontée, dans laquelle il est situé à l'écart de la surface d'appui 22, et une position encliquetée, dans laquelle les pattes 72 ont été insérées dans des ouvertures 74 respectives. Le déplacement du capot 18 par rapport à la surface d'appui 22 est possible indépendamment du connecteur 16 lorsque le connecteur 16 est placé à l'écart du capot 18, hors du logement 68.In this example, the cover 18 is movable relative to the bearing surface 22 between a disassembled position, in which it is located away from the bearing surface 22, and a snapped position, in which the legs 72 were inserted into respective openings 74. The displacement of the cover 18 relative to the bearing surface 22 is possible independently of the connector 16 when the connector 16 is placed away from the cover 18, out of the housing 68.

Dans la position encliquetée, les flancs latéraux 62A butent contre la surface d'appui 22. La surface supérieure 60 s'étend parallèlement à la surface d'appui 22 en regard des pistes 26A à 26C. Le logement 68 est ainsi délimité entre la surface 22, les flancs latéraux 62A, 62B et la paroi supérieure 60.In the latched position, the lateral flanks 62A abut against the bearing surface 22. The upper surface 60 extends parallel to the bearing surface 22 facing the tracks 26A to 26C. The housing 68 is thus defined between the surface 22, the lateral flanks 62A, 62B and the upper wall 60.

Le montage de la première pièce 10 d'équipement selon l'invention va maintenant être décrit.The mounting of the first piece of equipment according to the invention will now be described.

Initialement, le capot 18 est positionné en regard de la surface d'appui 22. Puis, les pattes d'encliquetage 72 sont introduites dans les ouvertures 74 respectives pour encliqueter le capot 18 dans la surface d'appui 22.Initially, the cover 18 is positioned facing the bearing surface 22. Then, the locking tabs 72 are introduced into the respective openings 74 to snap the cover 18 into the bearing surface 22.

Lorsque les flancs latéraux 62A, 62B butent contre la surface d'appui 22, les têtes d'encliquetage 76 coopèrent avec le corps 12 pour bloquer en position le capot 18 par rapport à la surface d'appui 22.When the lateral flanks 62A, 62B abut against the bearing surface 22, the detent heads 76 cooperate with the body 12 to lock the cover 18 in position relative to the bearing surface 22.

Puis, le connecteur électrique 16 est placé en appui sur la surface d'appui 22 au voisinage de l'ouverture d'insertion 70. A cet effet, la surface inférieure d'application 40 est appliquée sur la surface d'appui 22, ce qui provoque la compression des doigts 32A à 32C et du joint 30 entre les surfaces 22, 40.Then, the electrical connector 16 is placed in abutment on the bearing surface 22 in the vicinity of the insertion opening 70. For this purpose, the lower application surface 40 is applied on the bearing surface 22, which which causes compression of the fingers 32A to 32C and the seal 30 between the surfaces 22, 40.

Le connecteur 16 est alors déplacé le long de l'axe X-X' d'introduction vers le capot 18 par glissement sur la surface d'appui 22.The connector 16 is then moved along the insertion axis X-X 'towards the cover 18 by sliding on the bearing surface 22.

Lors de ce déplacement, la butée proximale 64A est poussée vers le haut par la surface supérieure 38 du boîtier 28. La surface distale 44 du boîtier 28 est introduite à travers l'ouverture d'insertion 70 et est déplacée vers la butée distale 64B.During this movement, the proximal stop 64A is pushed upward by the upper surface 38 of the housing 28. The distal surface 44 of the housing 28 is introduced through the insertion opening 70 and is moved toward the distal stop 64B.

Les nervures 66 sont simultanément introduites dans les rainures 48 respectives, pour guider le déplacement du connecteur 16 sous le capot 18 le long de l'axe X-X'.The ribs 66 are simultaneously inserted into the respective grooves 48, to guide the movement of the connector 16 under the hood 18 along the axis X-X '.

Lorsque la surface distale 44 du boîtier 28 entre en contact avec la butée distale 64B, la butée proximale 64A se déplace vers la surface d'appui 22 et s'applique contre la surface proximale 46 au-dessus du soufflet 34.When the distal surface 44 of the housing 28 contacts the distal abutment 64B, the proximal abutment 64A moves toward the abutment surface 22 and bears against the proximal surface 46 above the bellow 34.

Le connecteur 16 est alors bloqué de manière robuste en position montée sur le corps 12 par le capot 18. Le déplacement du connecteur 16 à l'écart de la surface d'appui 22 est empêché par la paroi supérieure 60. Le déplacement du connecteur 16 sur la surface d'appui 22 est bloqué transversalement par les flancs 62A, 62B, et axialement par les butées 64A, 64B.The connector 16 is then securely locked in position mounted on the body 12 by the cover 18. The displacement of the connector 16 away from the bearing surface 22 is prevented by the upper wall 60. The displacement of the connector 16 on the bearing surface 22 is blocked transversely by the flanks 62A, 62B, and axially by the stops 64A, 64B.

Dans cette position montée, les doigts 32A à 32B sont appliqués respectivement sur les pistes 26A à 26C, et une connexion électrique est réalisée entre le cheminement 14, les pistes 26A, 26B, 26C, les doigts 32A, 32B, 32C et le fil 36.In this mounted position, the fingers 32A to 32B are respectively applied to the tracks 26A to 26C, and an electrical connection is made between the path 14, the tracks 26A, 26B, 26C, the fingers 32A, 32B, 32C and the wire 36 .

Un espace étanche est délimité à l'intérieur du joint 30 entre la surface inférieure d'application 40, la surface d'appui 22 du corps 12, et le joint d'étanchéité 30. Le joint entoure les pistes 26A, 26B, 26C et les doigts 32A, 32B, 32C.A sealed space is delimited within the seal 30 between the lower application surface 40, the bearing surface 22 of the body 12, and the seal 30. The seal surrounds the tracks 26A, 26B, 26C and the fingers 32A, 32B, 32C.

Cet espace étanche reçoit les pistes 26A à 26C et les doigts 32A à 32C lorsque ces éléments sont raccordés électriquement les uns aux autres. Ceci améliore notablement la fiabilité du raccordement électrique notamment en milieu humide.This sealed space receives the tracks 26A to 26C and the fingers 32A to 32C when these elements are electrically connected to each other. This significantly improves the reliability of the electrical connection, particularly in a humid environment.

Lorsque le connecteur 16 doit être remplacé ou démonté, la butée supérieure 64A est soulevée vers le haut, ce qui libère le déplacement axial le long de l'axe X-X' du boîtier 28 à l'écart du capot 18, pour sortir le connecteur 16 du logement 68, puis le déplacer à l'écart de la surface d'appui 22.When the connector 16 must be replaced or disassembled, the upper stop 64A is raised upwards, which releases the axial displacement along the axis XX 'of the housing 28 away from the cover 18, to remove the connector 16 housing 68, then move it away from the bearing surface 22.

Le montage et le démontage du connecteur 16 sur le corps 12 de la pièce 10 est donc très simple à réaliser, ce qui facilite la maintenance du véhicule. Le capot 18 assure cependant une fixation robuste du connecteur 16 contre la surface d'appui 22, ce qui garantit une bonne connexion électrique et une fiabilité adéquate des équipements électriques portés par la pièce 10.The assembly and disassembly of the connector 16 on the body 12 of the part 10 is therefore very simple to perform, which facilitates the maintenance of the vehicle. The cover 18 however provides a robust attachment of the connector 16 against the bearing surface 22, which which guarantees a good electrical connection and an adequate reliability of the electrical equipment carried by the part 10.

La deuxième pièce d'équipement 80 selon l'invention, représentée sur la Figure 3, diffère de la première pièce 10 en ce que les butées 64A, 64B sont solidaires du connecteur 16. A cet effet, une patte de blocage 82 comportant les deux butées 64A, 64B est montée mobile par rapport à la surface supérieure 38 du boîtier 28.The second piece of equipment 80 according to the invention, represented on the Figure 3 , differs from the first piece 10 in that the stops 64A, 64B are integral with the connector 16. For this purpose, a locking tab 82 having the two stops 64A, 64B is movably mounted relative to the upper surface 38 of the housing 28 .

La patte 82 est mobile entre une position inférieure rétractée dans un logement 84 ménagé dans le boîtier 28, et une position supérieure de blocage dans laquelle les butées 64A, 64B font saillie vers le haut par rapport à la surface supérieure 38.The tab 82 is movable between a lower position retracted into a housing 84 formed in the housing 28, and an upper locking position in which the stops 64A, 64B protrude upwards relative to the upper surface 38.

Pour assurer le blocage, la paroi supérieure 60 du capot délimite une ouverture distale 86 traversante de réception de la butée distale 64B, et une échancrure proximale 88 de réception de la butée proximale 64A s'ouvrant dans le bord proximal du capot 18.To ensure the locking, the upper wall 60 of the cap delimits a distal abutment receiving aperture 86 for receiving the distal abutment 64B, and a proximal recess 88 for receiving the proximal abutment 64A opening in the proximal edge of the cap 18.

Lorsque le connecteur 16 est introduit sous le capot 18, la patte 82 occupe sa position supérieure. La coopération entre la butée distale 64B, introduite dans l'ouverture 86 et la paroi supérieure 60 empêche le déplacement longitudinal du boîtier 28 par rapport au capot 18 dans un premier sens le long de l'axe X-X'. La coopération entre la butée proximale 64A introduite dans l'échancrure 88 et la paroi supérieure 60 empêche le déplacement du boîtier 28 par rapport au capot 18 dans un deuxième sens le long de l'axe X-X'.When the connector 16 is inserted under the cover 18, the tab 82 occupies its upper position. The cooperation between the distal stop 64B, introduced into the opening 86 and the upper wall 60 prevents the longitudinal displacement of the housing 28 relative to the cover 18 in a first direction along the axis X-X '. The cooperation between the proximal stop 64A introduced into the notch 88 and the upper wall 60 prevents the housing 28 from moving relative to the cover 18 in a second direction along the axis X-X '.

Une troisième pièce d'équipement 90 selon l'invention est représentée sur la Figure 4. A la différence de la première pièce d'équipement 10, les pattes d'encliquetage 72 sont solidaires du corps 12 et les ouvertures de réception 74 sont ménagées dans les flancs latéraux 62A, 62B du capot 18. A cet effet, les pattes 72 font saillie vers le haut à partir de la surface 22 de part et d'autre des pistes 26A à 26C. Les ouvertures 74 sont ménagées à travers les flancs 62A, 62B et à travers les nervures 66.A third piece of equipment 90 according to the invention is represented on the Figure 4 . Unlike the first piece of equipment 10, the latching tabs 72 are integral with the body 12 and the receiving openings 74 are formed in the lateral flanks 62A, 62B of the cover 18. For this purpose, the tabs 72 are protruding upwards from the surface 22 on either side of the tracks 26A to 26C. The openings 74 are formed through the flanks 62A, 62B and through the ribs 66.

Le montage et le fonctionnement de la troisième pièce 90 est analogue à celui de la première pièce 10.The assembly and operation of the third piece 90 is similar to that of the first piece 10.

Une quatrième pièce d'équipement 100 est représentée sur la Figure 6. A la différence de la pièce 10 représentée sur la Figure 1, le capot 18 est fixé en permanence sur la surface d'appui 22. Le montage et le fonctionnement de la quatrième pièce 100 est analogue à celui de la première pièce 10 après la fixation du capot 18.A fourth piece of equipment 100 is shown on the Figure 6 . Unlike the part 10 shown on the Figure 1 , the cover 18 is fixed permanently on the bearing surface 22. The mounting and operation of the fourth piece 100 is similar to that of the first piece 10 after fixing the cap 18.
