Abstract

The male electrical connector comprises at least two conducting tongues or terminal blades (4,5,6,7) intended to be inserted into a female connector with corresponding sockets. There is also an electrical shunt (8) which short-circuits the terminals when the male connector is not fitted into the female connector. The shunt may be moved within the connector and is a U-shape with the branches of the 'U' folded back. The shape is such that the spring action of the 'U' urges the shunt into its connecting position. However, the force of the female part of the connector moves the shunt against this spring action to move it away from its connecting position.

Description

L'invention concerne un connecteur électrique mâle, destiné à coopérer avec un connecteur électrique femelle et, comportant un dispositif court-circuit dudit connecteur mâle, notamment en pré-utilisation ou en pré-installation.The invention relates to a male electrical connector, intended to cooperate with a female electrical connector and comprising a short-circuit device of said male connector, in particular in pre-use or in pre-installation.

Dans certains domaines d'application des connexions électriques, et plus particulièrement mais non limitativement dans le domaine de l'automobile, on fait appel de plus en plus souvent à des circuits électroniques mettant en oeuvre des courants électriques de particulièrement faible ampèrage. De fait, et si par inadvertance, on met en contact, par exemple par le corps humain, les deux bornes d'une connexion issue dudit circuit électrique ou électronique, par exemple simplement par la main, le corps humain présentant de manière connue une résistivité relativement faible, ledit circuit électronique peut être endommagé ou, à tout le moins, subir des modifications notamment en termes de tension de fonctionnement, tension - seuil, etc., rendant son usage impropre à sa destination première.In certain fields of application of electrical connections, and more particularly, but not limited to, in the automobile field, electronic circuits are used more and more often using electric currents of particularly low amperage. In fact, and if inadvertently, the two terminals of a connection coming from said electrical or electronic circuit are brought into contact, for example by the human body, for example simply by hand, the human body having in known manner a resistivity relatively weak, said electronic circuit can be damaged or, at the very least, undergo modifications in particular in terms of operating voltage, threshold voltage, etc., making its use improper for its primary purpose.

Afin de s'affranchir de cet inconvénient, on a proposé, par exemple dans le document FR-A-2 220 102, un connecteur intégrant un court-circuit, susceptible d'être désactivé lorsque la connexion est réalisée avec un autre connecteur.In order to overcome this drawback, there has been proposed, for example in document FR-A-2 220 102, a connector incorporating a short circuit, capable of being deactivated when the connection is made with another connector.

L'invention concerne un perfectionnement de ce type de connecteurs. Elle propose un connecteur électrique mâle, par exemple serti à l'extrémité des connexions issues dudit circuit électrique ou électronique, comportant un organe de court-circuit temporaire entre lesdites bornes, et typiquement un shunt. Ainsi, de par la mise en court-circuit desdites bornes ou fiches ou languettes de connexion mâles, aucun courant électrique ne peut transiter par la connexion correspondante, et partant dans le circuit électronique ou électrique auquel elle est reliée.The invention relates to an improvement of this type of connector. It provides a male electrical connector, for example crimped at the end of the connections from said electrical or electronic circuit, comprising a temporary short-circuit member between said terminals, and typically a shunt. Thus, by shorting said terminals or plugs or male connection tabs, no electric current can pass through the corresponding connection, and therefore in the electronic or electrical circuit to which it is connected.

L'invention concerne donc un connecteur électrique mâle comprenant au moins deux languettes ou fiches conductrices de l'électricité, destinées à être insérées dans un connecteur femelle comportant des bornes de connexion correspondantes. Il comprend en outre un shunt électrique destiné à court-circuiter lesdites fiches ou languettes lorsque le connecteur mâle n'est pas enfiché ou connecté dans le connecteur femelle, et dont l'action est neutralisée lorsque ledit connecteur est enfiché ou connecté dans le connecteur femelle.The invention therefore relates to a male electrical connector comprising at least two electrically conductive tabs or plugs, intended to be inserted in a female connector comprising corresponding connection terminals. It further comprises an electric shunt intended to short-circuit said plugs or tabs when the male connector is not inserted or connected in the female connector, and the action of which is neutralized when said connector is inserted or connected in the female connector .

Selon l'invention, le shunt est mobile, notamment en translation, et est susceptible de se translater entre au moins deux positions, sous l'action de l'enfichage du connecteur mâle au sein du connecteur femelle, respectivement une première position dans laquelle ledit shunt est au contact des fiches ou languettes conductrices de l'électricité, de telle sorte à établir un court-circuit entre lesdites fiches ou languettes, et une seconde position, dans laquelle le shunt n'est plus au contact avec lesdites fiches ou languettes, neutralisant ainsi l'action de court-circuit.According to the invention, the shunt is mobile, in particular in translation, and is capable of translating between at least two positions, under the action of plugging the male connector into the female connector, respectively a first position in which said shunt is in contact with electrically conductive plugs or tabs, so as to establish a short circuit between said plugs or tabs, and a second position, in which the shunt is no longer in contact with said plugs or tabs, thus neutralizing the short circuit action.

Avantageusement, ce shunt est constitué par une lame-ressort, réalisée en un matériau conducteur de l'électricité, sensiblement en forme de W, et dont la pointe centrale est nettement plus longue que les ailes latérales qui le définissent.Advantageously, this shunt is constituted by a leaf spring, made of an electrically conductive material, substantially in the shape of a W, and the central tip of which is clearly longer than the lateral wings which define it.

Selon l'invention également, chacune des fiches ou languettes comporte sur sa face ou sa surface en regard de l'autre languette une saillie, destinée à coopérer avec l'extrémité libre de chacune des ailes latérales du shunt en forme de W, afin de s'opposer à son retrait hors du connecteur.According to the invention also, each of the plugs or tabs has on its face or its surface opposite the other tab a projection, intended to cooperate with the free end of each of the lateral wings of the W-shaped shunt, in order to object to its removal from the connector.

Dans une autre forme de réalisation de l'invention, lors de la connexion partielle de l'extrémité des fiches ou languettes dans le connecteur femelle, le shunt joue encore son rôle de court-circuit, ledit shunt n'étant neutralisé que par enfichement ou insertion maximum du connecteur mâle au sein du connecteur femelle.In another embodiment of the invention, during the partial connection of the end of the plugs or tabs in the female connector, the shunt still plays its role of short circuit, said shunt being neutralized only by plugging in or inserting the male connector as much as possible within the female connector.

Selon une caractéristique avantageuse de l'invention, le shunt fonctionne de manière réversible. En d'autres termes, après avoir été neutralisé lors de l'enfichage ou du branchement du connecteur mâle dans le connecteur femelle, le shunt remplit à nouveau sa fonction de court-circuit lors du désenfichage ou du débranchement du connecteur mâle hors du connecteur femelle.According to an advantageous characteristic of the invention, the shunt operates in a reversible manner. In other words, after being neutralized when plugging in or plugging the male connector into the female connector, the shunt again fulfills its short-circuit function when plugging in or unplugging the male connector from the female connector .

Selon une autre caractéristique de l'invention, les fiches ou languettes métalliques conductrices de l'électricité sont revêtues d'un revêtement isolant, notamment en matière plastique, par surmoulage, définissant au voisinage de la surface externe de chacune des ailes latérales constitutives du shunt en W, des saillies propres à induire le retrait desdites ailes hors du contact des fiches ou languettes métalliques lors de l'enfichage ou du branchement du connecteur mâle dans le connecteur femelle, par action dudit connecteur femelle sur la pointe centrale dudit W, induisant de fait la descente ou la translation du shunt dans sa globalité selon un sens opposé au sens de branchement du connecteur mâle au sein du connecteur femelle.According to another characteristic of the invention, the electrically conductive metal plugs or tabs are coated with an insulating coating, in particular of plastic material, by overmolding, defining in the vicinity of the external surface of each of the lateral wings constituting the shunt in W, projections capable of inducing the withdrawal of said wings out of contact with metal plugs or tabs during the insertion or connection of the male connector in the female connector, by action of said female connector on the central tip of said W, inducing descends or translates the entire shunt in a direction opposite to the direction of connection of the male connector within the female connector.

La manière dont l'invention peut être réalisée et les avantages qui en découlent ressortiront mieux de l'exemple de réalisation qui suit, donné à titre indicatif et non limitatif, à l'appui des figures annexées.The manner in which the invention can be implemented and the advantages which result therefrom will emerge more clearly from the example of embodiment which follows, given by way of non-limiting example, in support of the appended figures.

La figure 1 est une représentation schématique en perspective sommaire du connecteur électrique mâle conforme à l'invention.Figure 1 is a schematic representation in summary perspective of the male electrical connector according to the invention.

La figure 2 est une représentation en coupe dudit connecteur électrique mâle dans une version légèrement plus évoluée.Figure 2 is a sectional representation of said male electrical connector in a slightly more advanced version.

La figure 3 est une représentation schématique en perspective de l'une des fiches ou languettes mâles conductrices de l'électricité dudit connecteur mâle.Figure 3 is a schematic perspective representation of one of the male electrical plugs or tabs of said male connector.

On a représenté en figure 1 une vue partiellement en perspective et en section du connecteur mâle conforme à l'invention. Ce connecteur mâle (1) peut se prolonger au-delà de sa zone de connexion par deux branches latérales (2), se terminant par un ergot d'enfichage (3), destiné, de manière connue, à interdire tout retrait intempestif du connecteur mâle hors du connecteur femelle, ce dernier étant, dans ce cas, pourvu de saillies correspondantes destinées à coopérer avec les ergots (3).There is shown in Figure 1 a partially perspective view in section of the male connector according to the invention. This male connector (1) can extend beyond its connection zone by two lateral branches (2), ending in a plug lug (3), intended, in known manner, to prevent any untimely withdrawal of the connector male outside the female connector, the latter being, in this case, provided with corresponding projections intended to cooperate with the lugs (3).

Dans l'exemple décrit, le connecteur (1) comporte deux éléments conducteurs de l'électricité, respectivement (4, 6) et (5, 7). Ces éléments sont par exemple réalisés en cuivre et s'étendent parallèlement l'un à l'autre au-delà du connecteur proprement dit, afin de pouvoir s'enficher dans un connecteur femelle, comportant des bornes ou prises correspondantes prévues à cet effet.In the example described, the connector (1) comprises two electrically conductive elements, respectively (4, 6) and (5, 7). These elements are for example made of copper and extend parallel to each other beyond the connector itself, in order to be able to plug into a female connector, comprising corresponding terminals or sockets provided for this purpose.

Ces éléments conducteurs ou fiches (4, 5) sont recouverts au niveau de leur base (6, 7), d'un matériau plastique isolant et ce par surmoulage, ce matériau pouvant être par exemple du polyamide 6.6 ou du polysulfure de phénylène, ces matériaux n'étant nullement limitatifs.These conductive elements or plugs (4, 5) are covered at their base (6, 7) with an insulating plastic material and this by overmolding, this material being for example polyamide 6.6 or phenylene polysulfide, these materials being in no way limiting.

Selon une caractéristique essentielle de l'invention, un shunt (8), réalisé en un matériau conducteur électrique, notamment sous la forme d'une lame métallique à effet ressort, est mis en place par simple insertion ainsi qu'on peut le voir sur les figures 1 et 2. Ce shunt (8) présente une forme générale en W, et est défini par deux ailes latérales (10,11) et une pointe centrale (9), s'étendant largement au-delà de l'extrémité libre desdites ailes latérales (10) et (11).According to an essential characteristic of the invention, a shunt (8), made of an electrically conductive material, in particular in the form of a metal strip with spring effect, is put in place by simple insertion as can be seen on Figures 1 and 2. This shunt (8) has a general shape in W, and is defined by two lateral wings (10,11) and a central tip (9), extending widely beyond the free end said side wings (10) and (11).

Par ailleurs, lesdites ailes latérales (10) et (11) présentent un effet ressort, induisant leur écartement par rapport à la pointe centrale (9), de telle sorte qu'en l'absence de toute contrainte, la dimension du shunt (8) est choisie de telle sorte que les ailes latérales (10) et (11) viennent au contact avec la base (6,7) des fiches conductrices (4) et (5), ainsi qu'on peut bien l'observer sur la figure 2.Furthermore, said lateral wings (10) and (11) have a spring effect, inducing their spacing with respect to the central tip (9), so that in the absence of any constraint, the dimension of the shunt (8 ) is chosen so that the lateral wings (10) and (11) come into contact with the base (6,7) of the conductive plugs (4) and (5), as can be seen on the figure 2.

Parallèlement, les extrémités libres des ailes latérales (10) et (11) du shunt (8) sont recourbées (12,13) l'une en direction de l'autre, de telle sorte à former une zone d'appui, afin de coopérer avec un épaulement respectif (14,15) ménagé au sein desdites bases (6) et (7) des fiches conductrices (4) et (5), de telle sorte à éviter tout retrait du shunt (8) hors du connecteur mâle.In parallel, the free ends of the lateral wings (10) and (11) of the shunt (8) are bent (12,13) one towards the other, so as to form a support zone, in order to cooperate with a respective shoulder (14,15) formed within said bases (6) and (7) of the conductive plugs (4) and (5), so as to avoid any withdrawal of the shunt (8) from the male connector.

En outre, le surmoulage opéré sur lesdits éléments conducteurs (4,5,6,7) est réalisé de telle sorte à d'une part, ménager un espace libre (17) et (18) sous les zones inférieures du shunt (20) et (21), et d'autre part, conférer une inclinaison telle, en appui avec lesdites ailes latérales (10) et (11), afin que lors de la translation du shunt (8) selon le sens indiqué par la flèche F, lesdites ailes latérales (10) et (11) s'écartent des conducteurs électriques (6) et (7), afin de neutraliser l'effet de shunt ou de court-circuit.In addition, the overmolding performed on said conductive elements (4,5,6,7) is carried out so as to, on the one hand, provide a free space (17) and (18) under the lower zones of the shunt (20) and (21), and on the other hand, confer such an inclination, in abutment with said lateral wings (10) and (11), so that during the translation of the shunt (8) in the direction indicated by the arrow F, said lateral wings (10) and (11) move away from the electrical conductors (6) and (7), in order to neutralize the effect of shunt or short-circuit.

Cette translation du shunt (8) s'effectue lors de l'enfichage ou du branchement du connecteur mâle dans le connecteur femelle. En effet, lors de cet enfichage, et préalablement au réel branchement, le connecteur femelle aboutit au nivau 0 représenté sur la figure 2. Puis, on procède à une insertion du connecteur mâle (1) dans le connecteur femelle jusqu'à arriver au niveau A, étape intermédiaire dans laquelle le shunt (8) agit toujours et remplit toujours son rôle de court-circuit entre les éléments conducteurs (4, 6) d'une part et (5, 7) d'autre part. Enfin, l'enfichement total ou branchement total du connecteur mâle (1) au sein du connecteur femelle, c'est-à-dire au niveau B, induit une poussée sur l'extrémité (9) de la pointe du shunt (8), induisant sa descente vers le bas selon la flèche F, et partant, neutralise son effet de court-circuit puisque les ailes latérales (10) et (11) ne sont alors plus en contact avec les bases (6) et (7) des fiches conductrices (4) et (5).This translation of the shunt (8) takes place when the male connector is plugged in or plugged into the female connector. Indeed, during this insertion, and prior to the real connection, the female connector ends at level 0 shown in FIG. 2. Then, the male connector (1) is inserted into the female connector until reaching the level A , intermediate stage in which the shunt (8) always acts and always fulfills its role of short circuit between the conducting elements (4, 6) on the one hand and (5, 7) on the other hand. Finally, the total insertion or total connection of the male connector (1) within the connector female, that is to say at level B , induces a push on the end (9) of the tip of the shunt (8), inducing its descent downwards according to arrow F, and therefore neutralizes its effect short-circuit since the lateral wings (10) and (11) are no longer in contact with the bases (6) and (7) of the conductive plugs (4) and (5).

Bien entendu, dans d'autres applications, le niveau intermédiaire A peut être supprimé. Il suffit pour ce faire, d'augmenter la longueur de la pointe (9) par rapport aux ailes latérales (10) et (11), de telle sorte que celle-ci aboutisse au niveau 0, c'est-à-dire au même plan que l'extrémité libre des languettes ou fiches conductrices (4) et (5).Of course, in other applications, the intermediate level A can be omitted. To do this, it suffices to increase the length of the tip (9) relative to the lateral wings (10) and (11), so that it ends at level 0 , that is to say at same plane as the free end of the conductive tabs or plugs (4) and (5).

On conçoit ainsi que dans l'exemple décrit, lors du débranchement du connecteur mâle hors du connecteur femelle, le shunt (8) de par son effet de rappel élastique, retrouve sa place initiale et remonte jusqu'à ce que les extrémités (12) et (13) des ailes latérales (10) et (11) viennent en butée contre les épaulements (14) et (15) des bases (6) et (7) des fiches conductrices (4) et (5). Sa fonction de court-circuit est alors réactivée. On aboutit donc à un shunt à court-circuit réversible.It is thus understood that in the example described, when the male connector is disconnected from the female connector, the shunt (8), by its elastic return effect, returns to its initial place and rises until the ends (12) and (13) lateral wings (10) and (11) abut against the shoulders (14) and (15) of the bases (6) and (7) of the conductive plugs (4) and (5). Its short circuit function is then reactivated. This therefore results in a reversible short-circuit shunt.

On observe également que le shunt peut facilement être escamoté si le besoin n'est pas nécessaire. Enfin, le connecteur ainsi réalisé permet, tout en disposant d'un court-circuit éventuel, de ne générer qu'un encombrement très réduit, tout particulièrement adapté à l'électronique et la micro-électronique ou l'industrie automobile notamment.We also observe that the shunt can easily be retracted if the need is not necessary. Finally, the connector thus produced allows, while having a possible short circuit, to generate only a very small footprint, particularly suitable for electronics and microelectronics or the automotive industry in particular.
