Description

Élément de connexion et douille équipée d'un tel élément de connexion.  Connection element and socket equipped with such a connection element.
Domaine de l'invention Field of the invention
La présente invention concerne le domaine des raccordements électriques étanches de fils isolés traversant une alvéole. Elle concerne notamment le domaine des douilles étanches, destinée à l'équipement automobile ou aéronautique, ainsi que les connecteurs étanches. The present invention relates to the field of sealed electrical connections of insulated wires passing through a cell. It particularly concerns the field of sealed sockets, intended for automotive or aeronautical equipment, as well as sealed connectors.
Etat de la technique State of the art
On connaît dans l'état de la technique une douille étanche décrite par le brevet japonais JP2001043946. Cette douille comprend un socle recevant une pluralité de contacts électriques . In the state of the art is known a sealed sleeve described by Japanese Patent JP2001043946. This socket comprises a base receiving a plurality of electrical contacts.
On connaît également par le brevet américain US5749743 une douille tubulaire pour recevoir le culot d'une ampoule électrique. La douille selon cet art antérieur présente une alvéole s 'étendant dans une direction perpendiculaire à l'axe de la douille et une alvéole s 'ouvrant sur la périphérie interne de la prise de la douille. Also known from US Pat. No. 5,749,743 is a tubular socket for receiving the base of a light bulb. The socket according to this prior art has a cell extending in a direction perpendicular to the axis of the socket and a socket opening on the inner periphery of the socket socket.
Les douilles étanches avec joint inséré dans une alvéole de l'art antérieur ne permettent pas le mariage de fils. Par mariage de fils, on entend une reprise électrique sur la voie alimentant la fonction et repartant vers une autre fonction du faisceau de fil. Sealed sleeves with seal inserted into a cell of the prior art do not allow the marriage of son. By marriage son, means an electrical recovery on the path feeding the function and departing to another function of the wire bundle.
Il est usuel, pour des feux automobile, d'alimenter un ensemble de douilles par un faisceau de fils comprenant une masse commune et des doublements de fonction pour l'alimentation en parallèle de plusieurs fonctions identiques. It is customary, for automobile fires, to feed a set of bushings by a wire bundle comprising a common ground and doubling of function for the parallel supply of several identical functions.
Ces fonctions sont les clignotants, les feux de position, les feux de recul...  These functions are the turn signals, the position lights, the reversing lights ...
Inconvénients de l'art antérieur Les douilles étanches de l'art antérieur nécessitent des faisceaux complexes, avec, pour chaque douille un fil de masse, et une liaison de ces multiples fils de masse à un fil de masse unique provenant du connecteur principal. Cette liaison est généralement réalisée par un sertissage isolé, le sertissage et l'isolation étant réalisés manuellement lors de la préparation du faisceau de fils. On a proposé, pour éviter cette opération complexe de préparation du faisceau de fils, de relier les masses des douilles en série, par un fil reprenant la masse d'une première douille et alimentant une seconde douille. Solution apportée par l'invention Disadvantages of prior art Prior art sealed bushings require complex bundles with, for each bushing, a ground wire, and a connection of these multiple ground wires to a single ground wire from the main connector. This connection is generally performed by insulated crimping, the crimping and the insulation being made manually during the preparation of the wire bundle. In order to avoid this complex operation of preparing the bundle of wires, it has been proposed to connect the masses of the sockets in series, by a wire taking up the mass of a first socket and feeding a second socket. Solution provided by the invention
Afin de remédier à cet inconvénient, l'invention concerne selon son acception la plus générale un élément de connexion pour un connecteur ou une douille étanchéifié par un joint inséré dans une alvéole et serti sur un fût, comprenant un contact électrique relié à au moins un fil caractérisé en ce que ledit élément comporte contact principal prolongé par un moyen de sertissage sur l'âme conductrice d'un premier fil principal, et un moyen de connexion parallèle d'un contact secondaire serti sur l'âme conductrice d'un second fil. In order to remedy this drawback, the invention relates, in its most general sense, to a connection element for a connector or socket sealed by a seal inserted in a cell and crimped onto a barrel, comprising an electrical contact connected to at least one wire characterized in that said element has main contact extended by a crimping means on the conductive core of a first main wire, and means for parallel connection of a secondary contact crimped on the conductive core of a second wire .
Selon un mode de réalisation particulier, ledit moyen de connexion présente une languette de détection prolongée par une zone de détection s 'éloignant du plancher, vers l'extérieur, lorsque le contact de reprise n'est engagée que partiellement dans ladite zone de réception, ladite languette de détection s 'effaçant dans le moyen de connexion lorsque le contact de reprise est engagée en position nominale . According to a particular embodiment, said connection means has a detection tab extended by a detection zone moving away from the floor, towards the outside, when the resumption contact is only partially engaged in said reception zone, said detection tab is erased in the connection means when the return contact is engaged in the nominal position.
Avantageusement, ledit moyen de connexion présente un contact de reprise prolongée par une zone de détection s 'éloignant du plancher, vers l'extérieur, lorsque le contact de reprise n'est engagée que partiellement dans ladite zone de réception, ledit contact de reprise s 'effaçant dans le moyen de connexion lorsque le contact de reprise est engagée en position nominale. Selon un mode de réalisation préféré, ledit fil principal traverse un joint d' étanchéification constitué par un bloc en un matériau élastique présentant des lèvres d'étanchéité périphériques de section complémentaire à la section de l'alvéole, et au moins un passage pour la traversée par un fil isolé. Advantageously, said connecting means has a prolonged resumption of contact by a detection zone moving away from the floor, towards the outside, when the resumption of contact is engaged only partially in said zone of reception, said resumption contact is erased in the connection means when the resumption contact is engaged in nominal position. According to a preferred embodiment, said main wire passes through a sealing joint consisting of a block made of an elastic material having peripheral sealing lips of complementary section to the section of the cell, and at least one passage for the crossing. by an insulated wire.
L'invention concerne également une douille comportant une alvéole pour l'engagement d'un élément de connexion comprenant un contact électrique relié à au moins un fil caractérisé en ce que ledit élément comporte un contact principal prolongé par un moyen de sertissage sur l'âme conductrice d'un premier fil principal, et un moyen de connexion d'un contact secondaire serti sur l'âme conductrice d'un second fil. The invention also relates to a socket comprising a socket for the engagement of a connection element comprising an electrical contact connected to at least one wire, characterized in that said element comprises a main contact extended by a crimping means on the core. conductor of a first main wire, and means for connecting a secondary contact crimped on the conductive core of a second wire.
Selon une variante, ledit élément de connexion présente un moyen de connexion comportant un contact de reprise s 'étendant à l'extérieur du plancher et empêchant l'engagement dans l'alvéole lorsque le contact de reprise n'est que partiellement engagé. According to a variant, said connecting element has a connection means comprising a return contact extending outside the floor and preventing engagement in the cell when the resumption of contact is only partially engaged.
Selon une autre variante, la douille comporte un verrou mécanique venant s'appuyer sur la face arrière du joint lorsque l'ensemble de connexion est en place. According to another variant, the bushing comprises a mechanical lock coming to rest on the rear face of the seal when the connection assembly is in place.
Dans ce cas, le dépassement du fût de sertissage lors d'un assemblage défectueux, avant que le contact de reprise ne sollicite la languette de détection empêche la mise en place dudit verrou mécanique. In this case, the overflow of the crimping drum during a faulty assembly, before the resumption of contact solicits the detection tab prevents the establishment of said mechanical lock.
Selon un mode de réalisation particulier, ledit élément de connexion présente un moyen de connexion comportant une languette de détection s 'étendant à l'extérieur du plancher et empêchant l'engagement dans l'alvéole lorsque le contact de reprise n'est que partiellement engagé. According to a particular embodiment, said connection element has a connection means comprising a detection tab extending outside the floor and preventing engagement in the cell when the return contact is only partially engaged.
Avantageusement, la douille selon l'invention comporte un verrou mécanique détectant le dépassement de la jupe de sertissage du contact s 'étendant au de là de la face arrière du joint par blocage de la fermeture dudit verrou. Advantageously, the socket according to the invention comprises a mechanical lock detecting the protrusion of the crimp skirt of the contact extending from the rear face of the seal by blocking the closure of said latch.

Le contact de reprise (7) est formé par découpe et mise en forme d'une feuille métallique. Il présente une section en forme de « L » avec une découpe (28) destinée à coopérer avec une languette de détection (29) prévu dans le plancher (18) . - Figure 4 shows a cutaway view of a contact element according to the invention, with the second engaged contact. The recovery contact (7) is formed by cutting and forming a metal sheet. It has an L-shaped section with a cutout (28) for cooperating with a detecting tab (29) provided in the floor (18).
La partie avant du contact de reprise (7) présente un méplat (33) avec un prolongement latéral (34) en équerre .  The front portion of the return contact (7) has a flat (33) with a lateral extension (34) at right angles.
La zone avant de ce prolongement latéral forme un chanfrein (35) découpé en biseau. La partie arrière du prolongement se termine par une butée (36) s 'étendant perpendiculairement .  The front zone of this lateral extension forms a bevel chamfer (35). The rear portion of the extension terminates in a stop (36) extending perpendicularly.
La partie avant du méplat (33) est surmontée par un repli (37) d'une largeur inférieure à la largeur du méplat.  The front portion of the flat (33) is surmounted by a fold (37) of a width less than the width of the flat.
La partie arrière du contact de reprise (7) comporte une jupe de sertissage conducteur (30) pour le sertissage sur l'âme conductrice du fil de reprise (8). Cette jupe de sertissage conducteur (30) est prolongée par une jupe de sertissage isolant (31) assurant le sertissage sur l'isolant du fil de reprise (8) .  The rear portion of the return contact (7) has a conductive crimp skirt (30) for crimping the conductive core of the pickup wire (8). This conductive crimp skirt (30) is extended by an insulating crimping skirt (31) crimping the insulation of the recovery wire (8).
Le contact principal (3) assure les différentes fonctions mécaniques et électriques : The main contact (3) provides the various mechanical and electrical functions:
- guidage du contact principal dans l'alvéole - guidance of the main contact in the cell
- butée du contact principal dans l'alvéole - stop of the main contact in the cell
- clipsage du contact dans l'alvéole  - clipping of the contact into the cell
- contact électrique sur la base de l'ampoule - electrical contact on the base of the bulb
- guidage intérieur destiné à recevoir le contact de reprise - internal guidance for receiving the recovery contact
- butée intérieure destinée au contact de reprise - plan d'appui du contact de reprise assurant le contact électrique de reprise  - internal stop intended for the return contact - support plane of the return contact ensuring the electrical contact of recovery
- plaquage du contact de reprise sur le plan d' appui  - plating of the contact of recovery on the plane of support
- verrouillage du contact de reprise  - recovery contact lock
- sertissage sur l'âme conductrice du fil principal (4)  - crimping on the conductive core of the main wire (4)
- sertissage sur un épaulement intérieur du joint (5) . Le fond (26) est découpé pour présenter une languette de détection (29) rectangulaire se terminant par une zone de détection (32) recourbée d'au moins 90°, et avantageusement environ 145° par pliage. crimping on an inner shoulder of the joint (5). The bottom (26) is cut to present a rectangular detecting tab (29) ending in a detection zone (32) bent by at least 90 °, and advantageously about 145 ° by folding.
Cette zone de détection (32) sert à la détection de l'engagement de la découpe (28) du contact de reprise (7) . Cette découpe (28) est constituée par une échancrure s 'ouvrant latéralement sur la partie plane (33) du contact de reprise (7) . La longueur de la découpe (28) est supérieure à la longueur de la zone de détection (32) . This detection zone (32) serves to detect the engagement of the cutout (28) of the resumption contact (7). This cutout (28) consists of a notch s' opening laterally on the flat portion (33) of the resumption contact (7). The length of the cutout (28) is greater than the length of the detection zone (32).
Le plancher (18) présente à sa partie arrière des guidages supérieures (38, 39) formé par des ailes repliées respectivement à 45° degrés environ et à 90° degrés environ. La tranche inférieure de ces ailes (38, 39) délimite, avec le plancher (18) un chemin de guidage du contact de reprise.  The floor (18) has at its rear end upper guides (38, 39) formed by wings folded at approximately 45 ° and approximately 90 ° degrees respectively. The lower edge of these wings (38, 39) delimits, with the floor (18) a guide path of the resumption contact.
La face latérale (40) présente un embouti (41) délimitant avec le fond du plancher (18) un guidage de la zone (34) du contact de reprise (7) .  The lateral face (40) has a stamping (41) delimiting with the bottom of the floor (18) guiding the zone (34) of the resumption contact (7).
Une partie recourbée (42) forme un ressort assurant le contact électrique avec le contact de reprise (7) .  A bent portion (42) forms a spring ensuring electrical contact with the resumption contact (7).
La tranche avant (43) de la partie recourbée (42) assure le verrouillage du contact de reprise (7) en venant en appui contre le bord avant (44) de son repli (37) .  The front edge (43) of the bent portion (42) ensures the locking of the return contact (7) bearing against the front edge (44) of its fold (37).
Le fond du plancher (18) présente des emboutis The bottom of the floor (18) has embossed
(45, 46) matérialisant l'appui plan du contact de reprise (7). (45, 46) embodying the plane support of the recovery contact (7).
La zone de détection (32) de la languette de détection (29) est repoussée vers l'extérieur, c'est à dire hors du gabarit du plancher (18) , lors de la pénétration de la zone avant du contact de reprise (7) . Lorsque cette zone de détection escamotée rencontre l'alvéole, elle empêche le montage de l'ensemble de connexion dans la douille.  The detection zone (32) of the detection tongue (29) is pushed outwards, that is to say outside the floor jig (18), during the penetration of the front zone of the return contact (7). ). When this retracted detection zone meets the cell, it prevents the assembly of the connection assembly in the socket.
Lorsque la zone de détection (32) arrive au droit de l'échancrure (28) du contact de reprise (7), elle s'efface en revenant dans le gabarit du plancher (18), ce qui autorise l'insertion de l'ensemble de connexion dans la douille .  When the detection zone (32) reaches the right of the notch (28) of the recovery contact (7), it disappears by returning to the floor template (18), which allows the insertion of the connection set in the socket.
La figure 5 représente une vue en coupe de la douille comprenant l'ensemble de connexion. L'engagement de l'ensemble de connexion n'est possible que lorsque la zone de détection est effacée, ce qui implique que le contact de reprise soit correctement engagé dans le contact principal. Figure 5 shows a sectional view of the socket comprising the connection assembly. Engagement of the connection assembly is only possible when the detection zone is cleared, which implies that the resetting contact is properly engaged in the main contact.
Dans le cas où le contact principal est engagé dans l'alvéole de la douille sans que le contact de reprise (7) ne soit engagé, la zone de détection obture la cavité du contact principal en s 'appuyant sur l'alvéole, ce qui empêche l'engagement a posteriori du contact de reprise (7) . Dans ce cas, le fut de sertissage (31) dépasse du joint (5) d'une manière manifeste, ce qui permet de détecter sans ambigϋité une mauvaise connexion.  In the case where the main contact is engaged in the cavity of the socket without the resetting contact (7) being engaged, the detection zone closes the cavity of the main contact by relying on the cell, which prevents the posterior engagement of the restart contact (7). In this case, the crimping (31) protrudes from the joint (5) in an obvious manner, which makes it possible to unambiguously detect a bad connection.
En d'autres termes, seule une connexion correcte du contact secondaire (7) sur le contact principal (3) permet un assemblage effectif de l'ensemble de connexion dans la douille.  In other words, only a correct connection of the secondary contact (7) on the main contact (3) allows effective assembly of the connection assembly in the socket.
Dans le cas où le contact de reprise est engagé de manière insuffisante pour repousser vers le bas la zone de détection (32), le montage de l'ensemble de connexion dans l'alvéole (2) de la douille (1) est certes possible, mais le fut de sertissage (31) dépassera nettement du joint (5) , ce qui indiquera le défaut de montage.  In the case where the return contact is insufficiently engaged to push down the detection zone (32), the assembly of the connection assembly in the socket (2) of the socket (1) is certainly possible , but the crimping (31) will clearly exceed the seal (5), which will indicate the mounting fault.
Optionnellement , un verrou mécanique peut venir s'appuyer sur la face arrière du joint (5) lorsque l'ensemble de connexion est en place. Dans ce cas, le dépassement du fut de sertissage (31) lors d'un assemblage défectueux empêche la mise en place dudit verrou mécanique.  Optionally, a mechanical lock can come to rest on the rear face of the seal (5) when the connection assembly is in place. In this case, exceeding the crimping (31) during a faulty assembly prevents the establishment of said mechanical lock.
