Description

L'invention concerne une cosse femelle pour connexion électrique présentant un logement pour la languette màle 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'ergot de verrouillage s'encliquetant dans une lumière réalisée dans la languette màle, l'extremité libre de cette patte faisant saillie au-delà des chants arriàre des bords recourbés pour former l'organe de libération.The invention relates to a female terminal for electrical connection having a housing for the male tongue of the connection and composed of a sole, a half shaft and two side walls, the two free edges of which are curved above the sole, the latter having a locking tab provided with a locking latch that snaps 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 .

On connaît déjà, par le document FR-A-2 269 802, une cosse femelle de contact électrique, réalisée en tôle et comprenant un logement de section transversale à peu près en "U", constituée d'une semelle de laquelle s'élèvent des parois latérales dont les bords libres sont recourbés vers ladite semelle, de manière qu'une languette complémentaire de contact puisse être introduite entre la base et les bords recourbés des parois latérales. Cette cosse comporte également une patte réalisée d'une seule pièce avec la semelle et faisant saillie à l'avant de cette dernière, c'est-à-dire à l'extrémité d'introduction de la languette dans le logement, la patte étant orientée vers l'arrière dudit logement, à l'intérieur de celui-ci. La patte, située dans le logement, comporte un ergot incliné vers l'arrière de cette patte et vers les bords recourbés des parois latérales, de manière à pouvoir se loger dans un trou ou une ouverture de la languette complémentaire lorsque celle-ci est emboîtée dans le logement, afin de verrouiller ladite languette et de l'empêcher ainsi d'être retirée du logement. L'extrémité libre de la patte fait saillie au-delà des extrémités arrière des bords recourbés des parois latérales et est recourbée perpendiculairement par rapport à la patte tout en s'éloignant de la semelle. Cette extrémité libre de la patte fait saillie par rapport au dessus des bords recourbés et forme un organe de libération. En appuyant sur cette extrémité, on repousse la patte élastiquement en direction de la semelle en l'éloignant des bords recourbés des parois laterales. De ce fait, l'ergot de verrouillage de la patte est dégagé du trou ou de l'ouverture de la languette emboitîtée dans le logement, ce qui permet de retirer la languette. Ainsi, la patte est repliée vers l'arrière de la cosse femelle et elle est pratiquement parallèle à la semelle.Already known, from document FR-A-2 269 802, a female electrical contact terminal, made of sheet metal and comprising a housing of cross section roughly in "U" shape, consisting of a sole from which rise side walls, the free edges of which are curved towards said sole, so that a complementary contact tab can be introduced between the base and the curved edges of the side walls. This lug also has a tab made in one piece with the sole and protruding at the front of the latter, that is to say at the insertion end of the tongue in the housing, the tab being oriented towards the rear of said housing, inside of it. The tab, located in the housing, has a lug inclined towards the rear of this tab and towards the curved edges of the side walls, so as to be able to be housed in a hole or an opening in the complementary tongue when the latter is fitted. in the housing, in order to lock said tab and thus prevent it from being removed from the housing. The free end of the tab projects beyond the rear ends of the curved edges of the side walls and is bent perpendicularly to the tab while moving away from the sole. This free end of the tab projects from the top of the curved edges and forms a release member. By pressing on this end, the tab is pushed back elastically in the direction of the sole, moving it away from the curved edges of the lateral walls. Therefore, the latch locking lug is released from the hole or the opening of the tongue fitted into the housing, which allows the tongue to be removed. Thus, the tab is folded back towards the rear of the female terminal and it is practically parallel to the sole.

Toutefois, du fait que la cosse femelle est réalisée en tôle, il est nécessaire de prévoir un rayon de courbure minimum a l'emplacement du pliage vers l'arrière de la patte sinon on risque, qu'à cet emplacement, la patte se déchire transversalement le long de la ligne de pliage. De ce fait, la cosse présente une hauteur importante, inconvénient notamment lorsqu'il s'agit de disposer des connexions dans des endroits réduits.However, because the female terminal is made of sheet metal, it is necessary to provide a minimum radius of curvature at the location of the folding towards the rear of the tab, otherwise there is a risk that at this location, the tab will tear transversely along the fold line. Therefore, the terminal has a significant height, a drawback especially when it comes to having the connections in reduced places.

Pour pallier à cet inconvénient, on a conçu une autre cosse femelle. Ainsi, on connaît, par le document FR-A-2 350 709 une cosse femelle destinée à être connectée à un conducteur électrique et à recevoir une languette màle de dimension correspondante. Cette cosse comprend un logement conforme pour recevoir et pour être connecté électriquement à la languette. Ce logement comprend une semelle dont la surface supérieure est sollicitée à l'usage au moins en partie par la languette. Ce logement présente une extrémité frontale ouverte par laquelle la languette est insérée en cours d'utilisation. On découpe la semelle de manière à obtenir à l'intérieur du logement une patte solidaire de la semelle et s'étendant dans une direction écartée de l'extrémité frontale ouverte du logement. Cette patte comprend un ergot qui s'étend vers l'intérieur du logement et qui, à l'usage, s'engage dans une ouverture formée dans la languette pour verrouiller celle-ci dans le réceptacle. Cette patte est ecartée par flexion vers le bas de la languette, pour extraire l'ergot de l'ouverture et libérer ainsi la languette. L'extrémité libre de cette patte s'étend vers le haut au-delà de ladite semelle pour faciliter la flexion de la patte, l'ergot étant situé entre les deux extrémités de la patte.To overcome this drawback, another female terminal has been designed. Thus, from document FR-A-2 350 709, a female terminal is known which is intended to be connected to an electrical conductor and to receive a male tab of corresponding size. This terminal includes a conforming housing for receiving and for being electrically connected to the tongue. This housing includes a soleplate, the upper surface of which is stressed at least in part by the tongue. This housing has an open front end through which the tab is inserted during use. The sole is cut so as to obtain inside the housing a tab integral with the sole and extending in a direction away from the open front end of the housing. This tab comprises a lug which extends towards the interior of the housing and which, in use, engages in an opening formed in the tongue to lock the latter in the receptacle. This tab is spread by bending down the tongue, to extract the lug from the opening and thus release the tongue. The free end of this tab extends upward beyond said sole to facilitate flexing of the tab, the lug being located between the two ends of the tab.

Toutefois, pour que l'extrémité libre s'étendevers le haut au-delà de ladite semelle, il est nécessaire d'allonger d'autant la cosse femelle. Ainsi, cette dernière ne correspond plus à la longueur définie par les normes et, de ce fait, on est obligé d'aménager spécialement les machines de pose permettant la fabrication des connexions. De plus, l'augmentation de la longueur de la cosse femelle entraîne nécessairement une augmentation de la matière utilisée pour former ladite cosse.However, for the free end to extend upwards beyond said sole, it is necessary to extend the female lug accordingly. Thus, the latter no longer corresponds to the length defined by the standards and, therefore, it is necessary to specially arrange the laying machines allowing the manufacture of the connections. In addition, increasing the length of the female lug necessarily leads to an increase in the material used to form said lug.

Pour pallier à cet inconvénient, on a conçu une cosse femelle connue par le document FR-A-2 412 180. Cette cosse femelle est réalisée à partir d'une feuille métallique conductrice de l'électricité convenablement découpée et pliée pour présenter, à une extrémité, des moyens de branchement à un conducteur électrique et, à son autre extrémité, un logement dont la section transversale affecte la forme d'un "U" avec une semelle et deux parois latérales, et destiné à recevoir une languette màle de contact de section méplate présentant, en un point intermédiaire de sa longueur, une ouverture destinée à coopérer avec un ergot d'une patte de retenue élastique de la cosse femelle. L'une des parois latérales de cette dernière comporte un prolongement qui est plié de manière à s'étendre au-dessus de la semelle. La patte élastique de retenue est constituée par une branche du prolongement s'étendant du côté de l'extrémité libre du logement et pliée à l'intérieur de celui-ci en direction de l'extrémité comportant les moyens de branchement. L'extrémité libre de la patte élastique est pliée en forme de crochet, traverse une lumière réalisée dans la semelle et fait saillie par rapport à la face inférieure de ladite semelle. Ainsi, pour le déverrouillage, il est nécessaire de repousser vers le haut l'extrémité libre de la patte élastique pliée en forme de crochet.To overcome this drawback, a female terminal known from document FR-A-2 412 180 has been designed. This female terminal is produced from an electrically conductive metal sheet suitably cut and folded to present, at a end, means for connection to an electrical conductor and, at its other end, a housing whose cross section affects the shape of a "U" with a sole and two side walls, and intended to receive a male contact tongue of flat section having, at an intermediate point of its length, an opening intended to cooperate with a lug of an elastic retaining tab of the female terminal. One of the side walls of the latter has an extension which is folded so as to extend above the sole. The elastic retaining tab is constituted by a branch of the extension extending from the side of the free end of the housing and folded inside of it in the direction of the end comprising the connection means. The free end of the elastic tab is folded in the form of a hook, passes through a lumen made in the sole and projects from the underside of said sole. Thus, for unlocking, it is necessary to push up the free end of the elastic tab folded in the shape of a hook.

Toutefois, il est très difficile d'accéder par le bas à la cosse femelle pour obtenir le déverrouillage. C'est pourquoi, on a été obligé de concevoir un élément de boîtier coiffant la connexion auquel on implique un certain mouvement pour l'effacement de cette extrémité libre. Cet élément du boîtier, connue par le document FR-A-2 445 633 est constitué d'un corps tubulaire réalisé en matière plastique moulée et présentant au moins un conduit destiné à recevoir la cosse femelle décrite ci-dessus. La surface interne de la paroi du conduit destiné à recevoir la cosse femelle et destinée à être tournée en regard de la surface supérieure du prolongement comporte un bossage présentant,du côté de l'extrémité d'introduction de la languette mâle de contact, un abrupt tandis que, de l'autre côté, ledit bossage forme une rampe inclinée de manière que, lors de la mise en place de la languette mâle de contact, le prolongement de celui-ci se déforme élastiquement en rencontrant le bossage puis reprend sa position initiale après avoir franchi l'abrupt.However, it is very difficult to access from the down to the female terminal to obtain the unlocking. This is why, we were forced to design a housing element covering the connection to which a certain movement is involved for the erasure of this free end. This element of the housing, known from document FR-A-2 445 633 consists of a tubular body made of molded plastic material and having at least one duct intended to receive the female terminal described above. The internal surface of the wall of the conduit intended to receive the female terminal and intended to be turned opposite the upper surface of the extension comprises a boss having, on the side of the insertion end of the male contact tongue, a steep while, on the other side, said boss forms an inclined ramp so that, when the male contact tongue is put in place, the extension thereof elastically deforms when it meets the boss and then returns to its initial position after crossing the steep.

Ainsi, il est nécessaire de prévoir une pièce supplémentaire pour permettre le déverrouillage de la connexion utilisant la cosse femelle conforme au document FR-A-2 412 180.Thus, it is necessary to provide an additional part to allow unlocking of the connection using the female lug conforming to document FR-A-2 412 180.

La présente invention a pour but de remédier à ces inconvénients et résout le problème consistant à créer une cosse femelle de hauteur réduite, de longueur conforme à celle des normes établies et dont le déverrouillage peut se faire facilement sans l'apport d'une pièce supplémentaire.The present invention aims to remedy these drawbacks and solves the problem of creating a female terminal of reduced height, of length in accordance with that of the established standards and the unlocking of which can be done easily without the addition of an additional part. .

L'invention est caractérisée en ce que la patte de verrouillage, pourvue de l'ergot de verrouillage, comporte une découpe en forme de "U" dont la découpe frontale est située du côté de l'ergot de verrouillage, 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 pour former l'organe de libération.The invention is characterized in that the locking tab, provided with the locking lug, comprises a "U" shaped cutout, the front cutout of which is situated on the side of the locking lug, defining a tongue which is practically folded back perpendicular to the tab upwards and projecting beyond the rear edges of the curved edges of the two side walls integral with the sole to form the release member.

Les avantages obtenus grâce à cette invention consistent essentiellement en ce qu'il est possible d'utiliser cette cosse femelle à des emplacements faibles en hauteur et de réduire son prix de revient par suite de la diminution de la quantité de matière utilisée et de la suppression de la pièce supplémentaire. De plus, il est possible d'utiliser les machines courantes du marché sans être obligé de procédér à une modification quelconque.The advantages obtained thanks to this invention consist essentially in the fact that it is possible to use this female terminal at locations low in height and to reduce its cost price due to the reduction in the quantity of material used and the elimination of the additional room. In addition, it is possible to use current machines on the market without being obliged to make any modification.

On se réfère aux figures 1 et 2.We refer to Figures 1 and 2.

La connexion 1, réalisée en un matériau conducteur d'électricité, se compose d'une cosse femelle 2, en un matériau conducteur d'électricité, notamment en tôle, et d'une languette mâle 3 s'insérant dans la cosse femelle 2. On assure le verrouillage entre la cosse femelle 2 et la languette mâle 3 par un ergot de verrouillage 4 solidaire de la cosse femelle 2 faisant saillie et pénétrant dans une lumière 5 pratiquée dans la languette mâle 3. Cet ergot de verrouillage 4, réalisé en un matériau élastique, présente une certaine inclinaison dont le point bas est le plus proche du chant frontal 6 de la cosse femelle 2. La languette mâle 3 comporte un chant d'attaque biseauté 7. Celui-ci, lors de l'introduction de la languette mâle 3 dans la cosse femelle 2, glisse le long de la face supérieure inclinée 8 de l'ergot de verrouillage 4 et, en raison de l'élasticité de ce dernier, pousse l'ergot de verrouillage 4 vers le bas. Après une certaine course, l'ergot de verrouillage 4 sous tension se trouve en face de la lumière 5 et en se détendant s'enclenche dans celle-ci. La languette mâle 3 ne peut plus s'échapper du fait que le chant transversal 9 de l'ergot de verrouillage 4 vient buter contre la paroi avant 10 de la lumière 5. Pour déverrouiller la connexion 1, il faut donc prévoir un organe de libéeration 11 provoquant l'effacement de l'ergot de verrouillage 4 et, notamment sa partie saillante.The connection 1, made of an electrically conductive material, consists of a female terminal 2, of an electrically conductive material, in particular of sheet metal, and of a male tab 3 fitting into the female terminal 2. Locking is provided between the female lug 2 and the male tab 3 by a locking lug 4 secured to the female lug 2 protruding and penetrating into a lumen 5 formed in the male tongue 3. This locking lug 4, produced in a elastic material, has a certain inclination, the bottom point of which is closest to the front edge 6 of the female terminal 2. The male tongue 3 has a beveled leading edge 7. This, when the tongue is introduced male 3 in the female terminal 2, slides along the inclined upper face 8 of the locking pin 4 and, due to the elasticity of the latter, pushes the locking pin 4 down. After a certain stroke, the locking lug 4 under tension is in front of the light 5 and by relaxing snaps into it. The male tongue 3 can no longer escape from the fact that the transverse edge 9 of the locking lug 4 abuts against the front wall 10 of the light 5. To unlock the connection 1, it is therefore necessary to provide a release member 11 causing the erasure of the locking lug 4 and, in particular its projecting part.

On se réfère aux figures 3 à 5.We refer to Figures 3 to 5.

La cosse femelle 2 comporte une semelle 12 servant de support à un demi-fût 13. Dans ce demi-fût 13 est sertie l'extrémité du fil conducteur (non représenté). En amont de ce demi-fût 13, la semelle 12 présente deux parois latérales 14, 15 servant de guide latéral aux chants latéraux 16, 17 de la languette mâle 3. Les bords libres 18, 19 de ces parois latérales 14, 15 sont recourbés au dessus de la semelle 12. Les chants supérieurs 20, 21 de ces bords libres 18, 19 prennent appui sur la face supérieure 22 de la languette mâle 3 pour annihiler tout jeu entre cette dernière et le logement 23 formé par la semelle 12, les deux parois latérales 14, 15 et les chants supérieurs 20, 21 des deux bords libres 18, 19, ce qui permet d'assurer un contact correct entre la cosse femelle 2 et la languette mâle 3.The female terminal 2 has a sole 12 serving as a support for a half-barrel 13. In this half-barrel 13 is crimped the end of the conductive wire (not shown). Upstream of this half-barrel 13, the sole 12 has two lateral walls 14, 15 serving as a lateral guide for the lateral edges 16, 17 of the male tongue 3. The free edges 18, 19 of these lateral walls 14, 15 are curved above the sole 12. The upper edges 20, 21 of these free edges 18, 19 bear on the upper face 22 of the male tongue 3 to eliminate any play between the latter and the housing 23 formed by the sole 12, the two side walls 14, 15 and the upper edges 20, 21 of the two free edges 18, 19, which ensures correct contact between the female lug 2 and the male tongue 3.

On pratique dans la semelle 12, à hauteur des parois latérales 14, 15, une découpe ayant une forme approximative d'un "U". La découpe frontale 24 est la plus éloignée par rapport au chant frontal 7 alors que les découpes latérales 25, 26, parallèles aux parois latérales 14, 15, sont dirigées vers le chant frontal 6 de la cosse femelle 2. On obtient ainsi une patte de verrouillage 27 à laquelle on confère un certain pliage autour de la ligne de pliage 28 de sorte que cette patte de verrouillage 27 soit parallèle et au-dessus de la semelle 12 lorsque le logement 23 est vide. A proximité de la ligne de pliage 28, on pratique une autre découpe 29 permettant d'obtenir l'ergot de verrouillage 4. La largeur de la patte de verrouillage 27 est supérieure à l'espace libre 30 situé entre les deux bords libres recourbés 18, 19. De ce fait, les chants supérieurs 20, 21 forment butée et limitent le relèvement de la patte de verrouillage 27.Is practiced in the sole 12, at the height of the side walls 14, 15, a cut having an approximate shape of a "U". The front cutout 24 is the farthest from the front edge 7 while the side cutouts 25, 26, parallel to the side walls 14, 15, are directed towards the front edge 6 of the female terminal 2. A tab is thus obtained. locking 27 to which a certain folding is imparted around the folding line 28 so that this locking tab 27 is parallel and above the sole 12 when the housing 23 is empty. AT near the fold line 28, another cut 29 is made, making it possible to obtain the locking lug 4. The width of the locking tab 27 is greater than the free space 30 located between the two curved free edges 18, 19. As a result, the upper edges 20, 21 form a stop and limit the raising of the locking tab 27.

Pour obtenir l'organe de libération 1, on pratique dans la patte de verrouillage 27 une seconde découpe ayant la forme d'un "U". La découpe frontale 31 est située du côté de l'ergot de verrouillage 4. On obtient ainsi une languette 32 que l'on replie vers le haut selon une ligne de pliage 33 de sorte que cette languette 32 est pratiquement perpendiculaire à la patte de verrouillage 27 et, par voie de conséquence, à la semelle 12. Cette ligne de pliage 33 est située au-delà des chants arrière 34, 35 des bords libres 18, 19 et, de ce fait, la languette 32 fait saillie au-delà desdits chants 34, 35. L'extrémité supérieure 36 de cette languette 32 est recourbée pour former un talon 37 facilitant la manipulation de la languette 32. Selon la figure 1, l'extrémité supérieure 36 est recourbée en direction du chant frontal 7 mais, selon la figure 4, cette extrémité supérieure 36 peut également être recourbée en direction du demi-fût 13. La largeur de cette languette 32 découpée dans la patte de verrouillage 27 est plus faible que l'espace libre 30. On pourvoit les chants arrière 34, 35 des bords libres 18, 19 des butées 38, 39. Ainsi, la languette 32 est maintenue vers l'avant par les butées 38, 39 et vers l'arrière par le demi-fût 13, ce qui arrête sa déformation.To obtain the release member 1, a second cut is made in the locking tab 27 having the shape of a "U". The front cutout 31 is located on the side of the locking lug 4. A tongue 32 is thus obtained which is folded upwards along a fold line 33 so that this tongue 32 is practically perpendicular to the locking tab. 27 and, consequently, the sole 12. This fold line 33 is located beyond the rear edges 34, 35 of the free edges 18, 19 and, as a result, the tongue 32 protrudes beyond said edges 34, 35. The upper end 36 of this tongue 32 is curved to form a heel 37 facilitating the manipulation of the tongue 32. According to FIG. 1, the upper end 36 is curved in the direction of the front edge 7 but, according to FIG. 4, this upper end 36 can also be bent in the direction of the half-barrel 13. The width of this tongue 32 cut out in the locking tab 27 is smaller than the free space 30. The rear edges 34 are provided, 35 free edges 18, 19 stops 38, 39. Thus, the tongue 32 is held forward by the stops 38, 39 and rearward by the half-barrel 13, which stops its deformation.

Comme visible dans la figure 1, lorsque la languette mâle 3 est engagée dans le logement 23, la patte de verrouillage 27 s'abaisse et vient se placer dans le logement 40 obtenu par suite de la découpe dans la semelle 12. De ce fait, le dessus 41 de la patte de verrouillage 27 est à fleur avec le dessus 42 de la semelle 12.As can be seen in FIG. 1, when the male tongue 3 is engaged in the housing 23, the locking tab 27 is lowered and is placed in the housing 40 obtained as a result of the cut in the sole 12. As a result, the top 41 of the locking tab 27 is flush with the top 42 of the sole 12.

Pour libérer la languette mâle 3, il faut appuyer sur le talon 37 et on pousse vers le bas la patte de verrouillage 27 provoquant le retrait de l'ergot de verrouillage 4 hors de la lumière 5 de la languette mâle 3.To release the male tab 3, the heel 37 must be pressed and the locking tab 27 is pushed down causing the locking pin 4 to be withdrawn from the slot 5 in the male tab 3.

Par contre, comme visible dans la figure 4, lorsque le logement 23 est vide, la patte de verrouillage 27 fait saillie et se place parallèlement au-dessus de la semelle 12.On the other hand, as visible in FIG. 4, when the housing 23 is empty, the locking tab 27 protrudes and is placed parallel above the sole 12.

Eventuellement, la cosse femelle peut être recouverte d'un capuchon unipolaire ou multipolaire.Optionally, the female terminal can be covered with a unipolar or multipolar cap.
