Description

L'invention concerne une cosse femelle pour connexion électrique présentant un logement pour la languette mâle de la connexion et composée d'une semelle, d'un demi-fût et de deux parois latérales dont les deux bords libres sont recourbés au-dessus de la semelle, cette dernière ayant une patte de verrouillage pourvue d'un ergot de verrouillage s'encliquetant dans une lumière réalisée dans la languette mâle, l'extrémité libre de cette patte faisant saillie au-delà des chants arrières des bords recourbés pour former l'organe de libération, soumis à un débattement vers le bas, cette patte de verrouillage pourvue de l'ergot de verrouillage comportant une découpe en forme de «U», dont la découpe frontale est située du côté de l'ergot de verrouillage, cette découpe définissant une languette repliée pratiquement perpendiculairement à la patte vers le haut et faisant saillie au-delà des chants arrière des bords recourbés des deux parois latérales solidaires de la semelle, ladite languette comportant une extrémité supérieure repliée en direction du demi-fût.The invention relates to a female terminal for electrical connection having a housing for the male tab of the connection and composed of a sole, a half-barrel and two side walls whose two free edges are curved above the sole, the latter having a locking tab provided with a locking latch snapping into a slot made in the male tongue, the free end of this tab projecting beyond the rear edges of the curved edges to form the release member, subjected to a downward movement, this locking tab provided with the locking lug comprising a “U” shaped cutout, the front cutout of which is located on the side of the locking lug, this cutout defining a folded tongue practically perpendicular to the tab upward and projecting beyond the rear edges of the curved edges of the two side walls integral with the sole, said tongue comprising with an upper end folded in the direction of the half barrel.

Ce type de cosse femelle trouve son application dans toute l'industrie électrique, et plus particulièrement dans l'industrie de l'électricité automobile, où l'on a besoin d'établir un grand nombre de connexions fiables, tout en étant aisément déverrouillables.This type of female terminal finds its application in all the electrical industry, and more particularly in the automobile electrical industry, where one needs to establish a large number of reliable connections, while being easily unlockable.

On connaît déjà, par le document FR-A-2 530875, une cosse femelle pour connexion électrique correspondant au préambule de la revendication 1. Son organe de libération est constitué par une languette découpée dans la patte de verrouillage, et repliée vers le haut, perpendiculairement à celle-ci. L'extrémité supérieure de cette languette fait saillie au-delà des chants arrière des bords recourbés des parois latérales solidaires de la semelle, et de plus, elle est repliée en direction du demi-fût de la cosse pour pouvoir être facile-. ment accessible et manoeuvrable lors du déverrouillage de la cosse.We already know, from document FR-A-2 530875, a female terminal for electrical connection corresponding to the preamble of claim 1. Its release member is constituted by a tongue cut out from the locking tab, and folded upwards, perpendicular to it. The upper end of this tongue projects beyond the rear edges of the curved edges of the side walls integral with the sole, and moreover, it is folded in the direction of the half-barrel of the thimble so that it can be easy. accessible and maneuverable when unlocking the terminal.

Cependant, du fait de ses faibles dimensions et de sa faible résistance mécanique à la flexion, la patte de verrouillage de la cosse est extrêmement fragile et constitue le point faible de la connexion. Aussi, toute manipulation incorrecte, notamment au cours du déverrouillage, risque de se solder par la destruction de la connexion, ou par l'existence d'un mauvais contact électrique entre la languette mâle et la cosse femelle. Plus précisément, lors du déverrouillage de la connexion, il faut appuyer sur la languette saillante de façon à repousser la patte de verrouillage vers le bas tel que connu en soi, et ainsi libérer l'ergot de verrouillage retenu dans la lumière réalisée dans la languette mâle. Pendant cette manoeuvre, il arrive fréquemment que la force appliquée sur la languette fasse passer la patte de verrouillage au travers de la découpe en «U» de la semelle, provoquant ainsi une flexion exagérée de celle-ci, supérieure à la limite élastique du métal. De ce fait, la patte de verrouillage ne peut plus revenir à sa position initiale, et le contact ultérieur entre la cosse femelle et la languette mâle risque d'être de mauvaise qualité, voire inexistant.However, due to its small dimensions and its low mechanical resistance to bending, the lug locking tab is extremely fragile and constitutes the weak point of the connection. Also, any improper handling, especially during unlocking, may result in the destruction of the connection, or the existence of poor electrical contact between the male tab and the female terminal. More specifically, when unlocking the connection, it is necessary to press on the projecting tab so as to push the locking tab down as known per se, and thus release the locking pin retained in the lumen produced in the tongue male. During this maneuver, it frequently happens that the force applied to the tongue causes the locking tab to pass through the “U” cutout in the sole, thus causing an exaggerated flexion of the latter, greater than the elastic limit of the metal. . Therefore, the locking tab can no longer return to its initial position, and subsequent contact between the female terminal and the male tongue may be of poor quality, or even non-existent.

La présente invention a pour but de remédier à ces inconvénients. L'invention telle qu'elle est caractérisée dans les revendications, résout le problème consistant à pourvoir la cosse femelle de moyens permettant de limiter le débattement vers le bas de l'organe de libération, et de ne lui faire subir que de légers déplacements, afin d'éviter la fatigue et la déformation permanente du métal tout en profitant de ces moyens de limitation de débattement pour bloquer la cosse dans son boîtier isolant.The present invention aims to remedy these drawbacks. The invention as characterized in the claims, solves the problem of providing the female terminal with means making it possible to limit the downward movement of the release member, and to make it undergo only slight displacements, in order to avoid fatigue and permanent deformation of the metal while taking advantage of these travel limitation means to block the terminal in its insulating housing.

Les avantages obtenus grâce à cette invention consistent essentiellement en ceci que le risque d'une déformation excessive de la patte de verrouillage étant éliminé, un opérateur peut aisément manipuler la cosse femelle sans la détériorer, et de surcroît, sans crainte de séparer la cosse de son boîtier isolant.The advantages obtained thanks to this invention consist essentially in that the risk of excessive deformation of the locking tab being eliminated, an operator can easily handle the female terminal without damaging it, and moreover, without fear of separating the terminal from its insulating housing.

L'invention est exposée ci-après plus en détail à l'aide de dessins représentant seulement un mode d'exécution.The invention is set out below in more detail with the aid of drawings representing only one embodiment.

la fig. 5 représente une vue en élévation partiellement en coupe de la cosse femelle conforme à l'invention, la cosse étant positionnée dans un connecteur et représentée pendant la phase de déverrouillage.fig. 5 shows an elevational view partially in section of the female terminal according to the invention, the terminal being positioned in a connector and shown during the unlocking phase.

Telle que représentée sur les fig. 1, 2, 3 et 4, la connexion 1 se compose d'une cosse femelle 2 et d'une languette mâle 3, toutes deux réalisées en un matériau conducteur d'électricité.As shown in Figs. 1, 2, 3 and 4, the connection 1 consists of a female terminal 2 and a male tab 3, both made of an electrically conductive material.

La languette mâle 3 comporte un chant d'attaque 7 biseauté, ainsi qu'une lumière 5 pratiquée dans son corps.The male tongue 3 has a bevelled attack edge 7, as well as a light 5 made in its body.

La cosse femelle 2 comporte une semelle 12 servant de support, d'une part, à un demi-fût 13, d'autre part à deux parois latérales 14 et 15.The female terminal 2 has a sole 12 serving as a support, on the one hand, for a half-barrel 13, and on the other hand for two side walls 14 and 15.

Le demi-fût 13 permet de réaliser la liaison de la cosse femelle 2 avec un conducteur électrique (non représenté), ce dernier étant serti dans le demi-fût 13.The half-barrel 13 allows the connection of the female terminal 2 with an electrical conductor (not shown), the latter being crimped in the half-barrel 13.

Les parois latérales 14 et 15 ont leurs bords libres 18 et 19 recourbés au-dessus de la semelle 12, de façon à délimiter un logement 23 qui constitue un réceptacle pour la languette mâle 3.The side walls 14 and 15 have their free edges 18 and 19 curved above the sole 12, so as to delimit a housing 23 which constitutes a receptacle for the male tongue 3.

La cosse femelle 2 comporte, en outre, une patte de verrouillage 27 destinée à retenir la languette mâle 3 dans le logement 23.The female lug 2 further comprises a locking tab 27 intended to retain the male tab 3 in the housing 23.

Cette patte de verrouillage 27 est obtenue par une découpe pratiquée dans la semelle 12, et ayant approximativement la forme d'un «U», dont les branches sont dirigées vers le chant frontal 6 de la cosse femelle 2.This locking tab 27 is obtained by a cutout made in the sole 12, and having approximately the shape of a "U", the branches of which are directed towards the front edge 6 of the female terminal 2.

La languette de verrouillage 27 comporte un ergot de verrouillage 4 élastique, et faisant saillie par rapport au dessus de la patte de verrouillage 27. Celle-ci comporte, en outre, un organe de libération 11 permettant d'assurer de déverrouillage de la connexion 1.The locking tab 27 has a resilient locking lug 4, and protruding from the top of the locking tab 27. The latter further comprises a release member 11 enabling the connection 1 to be unlocked. .

Cet organe de libération 11 est composé d'une languette 32 obtenue par une seconde découpe en forme de «U» réalisée dans ladite patte de verrouillage 27.This release member 11 is composed of a tongue 32 obtained by a second cut in the shape of a "U" produced in said locking tab 27.

La languette 32 obtenue par cette découpe est repliée vers le haut selon une ligne de pliage 33 située ou-delà des chants arrière 34, 35 des bords libres 18, 19. L'extrémité supérieure 36 de cette languette 32 est recourbée notamment en direction du demi-fût 13 pour former un talon 37 facilitant la manipulation de la languette 32.The tongue 32 obtained by this cutout is folded upwards along a fold line 33 situated or beyond the rear edges 34, 35 of the free edges 18, 19. The upper end 36 of this tongue 32 is curved in particular in the direction of the half-barrel 13 to form a heel 37 facilitating the manipulation of the tongue 32.

La patte de verrouillage 27 à laquelle a été conféré un certain pliage autour de la ligne pliage 28, est située au-dessus de la semelle 12 et parallèlement à celle-ci lorsque le logement 23 est vide.The locking tab 27 which has been given a certain fold around the fold line 28, is located above the sole 12 and parallel to it when the housing 23 is empty.

Par ailleurs, la largeur de cette patte de verrouillage 27 est supérieure à l'espace libre 30 situé entre les bords recourbés 18,19.Furthermore, the width of this locking tab 27 is greater than the free space 30 located between the curved edges 18, 19.

Ainsi, lors du verrouillage de la connexion 1, la languette mâle 3 est introduite dans le logement 23 de la cosse femelle 2 jusqu'à ce que l'ergot de verrouillage 4 se trouve en face de la lumière 5 et vienne, du fait de son élasticité, s'enclencher dans celle-ci, verrouillant ainsi la connexion 1.Thus, when the connection 1 is locked, the male tab 3 is inserted into the housing 23 of the female terminal 2 until the locking lug 4 is opposite the lumen 5 and comes, due to elasticity, snap into it, thus locking connection 1.

Il est à noter que, du fait qu'il faut protéger la patte de verrouillage 27, il ne faut lui faire subir que de légers déplacements, afin d'éviter la fatigue ou la déformation permanente du métal.It should be noted that, since it is necessary to protect the locking tab 27, it should only be subjected to slight displacements, in order to avoid fatigue or permanent deformation of the metal.

Dans l'état actuef de ta technique, ceci est réalisé uniquement lorsque le débattement de la patte de verrouillage 27 s'effectue vers le haut, puisque les chants supérieurs 20, 21 des ailes 14, 15 recourbées, forment des butées et limitent le relèvement de la patte de verrouillage 27.In the current state of your technique, this is achieved only when the movement of the locking tab 27 is carried upwards, since the upper edges 20, 21 of the curved wings 14, 15 form stops and limit the raising of the locking tab 27.

Au contraire, sur la cosse conforme à la présente invention, des moyens sont également fournis pour permettre de limiter le débattement vers le bas, de l'organe de libération 11 constitué de la patte de verrouillage 27 et de la languette 32.On the contrary, on the terminal in accordance with the present invention, means are also provided to limit the downward movement of the release member 11 consisting of the locking tab 27 and the tongue 32.

Dans un mode de réalisation et particulièrement simple de l'invention, ces moyens de limitation du débattement vers le bas de l'organe de libération 11 consistent en une butée d'arrêt 43 solidaire de la semelle 12 et située notamment mais non exclusivement au niveau de la découpe frontale 24.In an embodiment and particularly simple of the invention, these means for limiting the downward movement of the release member 11 consist of a stopper 43 secured to the sole 12 and located in particular but not exclusively at of the front cutout 24.

Cette butée d'arrêt 43 peut être obtenue à partir de la découpe frontale 24 correspondant à la base de la découpe en «U», par estampage ou par matriçage d'une partie de la zone périphérique de la découpe 24, solidaire de la semelle 12.This stop 43 can be obtained from the front cut 24 corresponding to the base of the "U" cut, by stamping or by stamping part of the peripheral zone of the cut 24, integral with the sole 12.

Cette opération a pour effet de créer un aplatissement et une avancée de la zone périphérique de la découpe frontale 24, formant ainsi la butée d'arrêt 43.This operation has the effect of creating a flattening and a projection of the peripheral zone of the front cutout 24, thus forming the stopper 43.

De ce fait, lors du déverrouillage de la connexion 1, le débattement vers le bas de la patte de verrouillage 27 est arrêté par la butée d'arrêt 43, permettant de limiter la contrainte de flexion à une valeur acceptable pour le métal, c'est-à-dire inférieure à sa limite élastique.Therefore, when the connection 1 is unlocked, the downward movement of the locking tab 27 is stopped by the stop stop 43, making it possible to limit the bending stress to an acceptable value for the metal, it that is to say less than its elastic limit.

Afin que le débattement de la patte de verrouillage 27 soit néanmoins suffisant pour permettre le déverrouillage en libérant l'ergot de verrouillage 4, la patte de verrouillage 27 est, au moins sur sa partie terminale 44 comportant la languette 32, inclinée vers le haut par rapport à la semelle 12.So that the clearance of the locking tab 27 is nevertheless sufficient to allow unlocking by releasing the locking pin 4, the locking tab 27 is, at least on its end portion 44 comprising the tongue 32, inclined upwards by compared to the sole 12.

Ceci a une autre conséquence avantageuse puisque, la connexion 1 étant en position verrouillée, la languette mâle 3 se trouve plaquée contre les chants 20, 21 de la cosse femelle 2, du fait de l'inclinaison vers le haut et de l'élasticité de la patte de verrouillage 27.This has another advantageous consequence since, the connection 1 being in the locked position, the male tab 3 is pressed against the edges 20, 21 of the female terminal 2, due to the upward inclination and the elasticity of the locking tab 27.

Il en résulte un meilleur contact électrique entre la languette mâle 3 et la cosse femelle 2. De plus, cette inclinaison de la patte de verrouillage 27 vers le haut contribue à rendre l'organe de libération 11 plus accessible.This results in better electrical contact between the male tongue 3 and the female terminal 2. In addition, this inclination of the locking tab 27 upwards contributes to making the release member 11 more accessible.

Dans le cas où, comme représenté sur la fig. 5, la cosse femelle 2 selon l'invention est utilisée conjointement avec un boîtier isolant 45, elle comporte des moyens permettant de la maintenir solidaire de celui-ci lors du déverrouillage.In the event that, as shown in FIG. 5, the female terminal 2 according to the invention is used in conjunction with an insulating housing 45, it comprises means making it possible to keep it integral with the latter during unlocking.

En effet, le boîtier isolant 45 possède préférentiellement une rampe oblique 50 aménagée sur sa face interne supérieure 51. De ce fait, lors du déverrouillage de la connexion 1 par traction du boîtier 45 vers la droite (fig. 5), la patte de verrouillage 27 est actionnée vers le bas par la rampe oblique 50.Indeed, the insulating housing 45 preferably has an oblique ramp 50 arranged on its upper internal face 51. As a result, when the connection 1 is unlocked by pulling the housing 45 to the right (fig. 5), the locking tab 27 is actuated downwards by the oblique ramp 50.

Cependant, la butée d'arrêt 43 arrête cette course vers le bas de la patte de verrouillage 27. De ce fait, lors du déverrouillage, le sommet de la languette 32, en contact avec la rampe oblique 50 du boîtier 45, permet de retenir celui-ci de façon à ce qu'il reste fixé à la cosse femelle 2.However, the stopper 43 stops this downward stroke of the locking tab 27. Therefore, during unlocking, the top of the tongue 32, in contact with the oblique ramp 50 of the housing 45, makes it possible to retain this so that it remains attached to the female terminal 2.

Ainsi, l'organe de libération 11 de la cosse femelle 2 constitue également, en coopération avec la butée d'arrêt 43, un moyen de blocage particulièrement simple et économique du boîtier isolant 45.Thus, the release member 11 of the female terminal 2 also constitutes, in cooperation with the stopper 43, a particularly simple and economical blocking means of the insulating housing 45.
