Les organes de connexion mâles se présentent sous la forme de barreaux cylindriques et sont destinés à s'insérer dans les connecteurs femelles correspondant, tandis que les deux parties du boîtier sont destinées à se fixer l'une sur l'autre pour réaliser la connexion.The present invention relates to an electrical connector of the type comprising a first housing part provided with a series of parallel channels in which are housed female cylindrical connection members and a second housing part provided with a series of parallel channels in which are guided male connection members. The male connection members are in the form of cylindrical bars and are intended to be inserted in the corresponding female connectors, while the two parts of the housing are intended to be fixed one on the other to make the connection.

On connaît de très nombreux connecteurs de ce type, tel que celui divulgué par le document FR-A-2377715 et correspondant au préambule de la revendication 1. L'un des buts de la présente invention est de réaliser un connecteur qui soit d'un montage relativement simple et qui permet la mise en place d'une manière mécanisée des différents organes de connexion mâles ou femelles dans leur canaux respectifs.Many connectors of this type are known, such as that disclosed in document FR-A-2377715 and corresponding to the preamble of claim 1. One of the aims of the present invention is to provide a connector which is of a relatively simple assembly and which allows the establishment in a mechanized manner of the different male or female connection members in their respective channels.

Le connecteur objet de la présente invention est du type comportant une première partie de boîtier isolant pourvue d'une série de canaux parallèles et destiné à recevoir dans chaque canal un organe de connexion femelle cylindrique pourvu à une extrémité de moyens de fixation d'un conducteur électrique, chaque dit canal comportant une ouverture d'introduction de l'organe de connexion femelle et des moyens de retenue desdits organes de connexion femelles, et une seconde partie de boîtier isolant pourvue d'une série de canaux parallèles destinés à recevoir, chacun, un organe de connexion mâle, chaque canal comportant une ouverture d'introduction de l'organe de connexion mâle et des organes de retenue desdits organes de connexion mâles, ceux-ci étant pourvus à une extrémités de moyens de fixation d'un conducteur électrique, tandis que l'autre extrémité est terminée par un barreau cylindrique destiné à s'insérer dans un organe femelle cylindrique correspondant, l'une des deux parties de boîtier étant prolongée par une jupe destinée à recevoir l'autre partie de boîtier et des moyens de verrouillage étant prévus pour maintenir les deux parties de boîtier assemblées, ledit connecteur étant caractérisé en ce que la première partie de boîtier est constituée de deux éléments de boîtier, le premier élément comportant les canaux qui sont pourvus, à l'extrémité opposée l'extrémité d'introduction de l'organe de connexion femelle, d'une butée pour retenir l'extrémité libre dudit organe et au moins d'une saillie portée par une patte élastique et destinée à coopérer avec le bord d'une collerette tourné vers les moyens de fixation du conducteur électrique et formée à l'extrémité libre dudit organe de connexion femelle, le second élément étant formé d'un corps destiné à recevoir le premier élément avec un fond percé de trous destinés à coïncider avec les canaux, des moyens de verrouillage étant prévus pour maintenir les deux éléments assemblés, la seconde partie de boîtier étant formée de deux éléments, le premier élément comportant les canaux destinés à recevoir les organes de connexion mâles, ceux-ci comportant en un point intermédiaire de leur longueur un collet, dont une extrémité est destinée à coopérer avec le bord de trous prévus à une extrémité des canaux et destinée à être traversés par les barreaux, tandis que lesdits canaux comportent des saillies portées par des pattes élastiques et destinées à coopérer avec l'autre extrémité du collet, ce dit premier élément étant destiné à s'insérer dans une jupe du second élément, des moyens étant prévus pour assurer le verrouillage des deux dits éléments assemblés. Une telle réalisation se prête particulièrement bien à la mécanisation.The connector object of the present invention is of the type comprising a first part of an insulating housing provided with a series of parallel channels and intended to receive in each channel a cylindrical female connection member provided at one end with means for fixing a conductor electric, each said channel comprising an opening for introducing the female connection member and means for retaining said female connection members, and a second part of an insulating housing provided with a series of parallel channels each intended to receive, a male connection member, each channel comprising an opening for introducing the male connection member and retaining members for said male connection members, the latter being provided at one end with means for fixing an electrical conductor, while the other end is terminated by a cylindrical bar intended to be inserted in a corresponding cylindrical female member, one of the two housing parts being extended by a skirt intended to receive the other housing part and locking means being provided to hold the two housing parts assembled, said connector being characterized in that the first housing part consists of two housing elements, the first element comprising the channels which are provided, at the opposite end with the insertion end of the female connection member, with a stop for retaining the free end of said member and at least one projection carried by an elastic tab and intended to cooperate with the edge of a collar turned towards the means for fixing the electrical conductor and formed at the free end of said female connection member, the second element being formed of a body intended to receive the first element with a drilled bottom holes intended to coincide with the channels, locking means being provided to keep the two elements assembled, the second part of housing being formed of two elements, the first element comprising the channels intended to receive the male connection members, these comprising at a point intermediate their length a collar, one end of which is intended to cooperate with the edge of holes provided for one end of the channels and intended to be crossed by the bars, while the said channels have projections carried by elastic tabs and intended to cooperate with the other end of the collar, said first element being intended to be inserted in a skirt of the second element, means being provided for locking the two said assembled elements. Such an embodiment lends itself particularly well to mechanization.

Suivant un détail constructif chaque canal du premier élément de la première partie de boîtier isolant comporte une saillie sur une paroi interne avec une rampe inclinée du côté d'une ouverture d'introduction des organes de connexion femelles, ladite saillie étant terminée par un abrupt.According to a constructive detail, each channel of the first element of the first part of the insulating housing has a projection on an internal wall with a ramp inclined on the side of an opening for introducing the female connection members, said projection being terminated by a steep.

Suivant encore une caractéristique constructive, chaque patte élastique de chaque canal du premier élément de la première partie de boîtier comporte une saillie conformée pour présenter du côté de l'ouverture d'introduction des organes de connexion femelles, une rampe inclinée terminée par un abrupt, ce dernier et l'abrupt de la saillie de chaque canal sont situés dans un même plan perpendiculaire à l'axe longitudinal du canal.According to yet another constructive characteristic, each elastic tab of each channel of the first element of the first housing part has a projection shaped to present, on the side of the opening for introducing the female connection members, an inclined ramp terminated by a steep, the latter and the abrupt projection of each channel are located in the same plane perpendicular to the longitudinal axis of the channel.

De préférence, chaque patte élastique du premier élément de la première partie de boîtier comporte, sur sa face tournée du côté opposé à celle pourvue de la saillie, une nervure ayant une hauteur telle que lorsque le premier élément et le second élément sont assemblés, ladite patte élastique est sollicitée en direction de l'organe de connexion femelle. Ainsi, on est assuré que l'organe de connexion femelle sera parfaitement verrouillé à l'intérieur du canal du premier élément de la première partie de boîtier.Preferably, each elastic tab of the first element of the first housing part comprises, on its face turned to the side opposite to that provided with the projection, a rib having a height such that when the first element and the second element are assembled, said elastic tab is biased towards the female connection member. Thus, it is ensured that the female connection member will be perfectly locked inside the channel of the first element of the first housing part.

Suivant encore une caractéristique constructive, le premier élément de la première partie de boîtier comporte sur deux côtés opposés des ergots de verrouillage, tandis que le second élément de ladite première partie est pourvue de trous destinés a recevoir lesdits ergots moyennant une déformation élastique. Ainsi lorsque le premier élément et le deuxième élément de la première partie de boîtier sont assemblés, ils ne peuvent plus être désaccouplés, ce qui constitue une sécurité pour le montage.According to another constructive characteristic, the first element of the first housing part comprises on two opposite sides locking lugs, while the second element of said first part is provided with holes intended to receive said lugs by means of elastic deformation. Thus when the first element and the second element of the first housing part are assembled, they can no longer be uncoupled, which constitutes security for mounting.

Suivant un détail constructif, chaque organe de connexion femelle est réalisé à partir d'une bande métallique bonne conductrice de l'électricité, convenablement découpée pour présenter à une extrémité des pattes de sertissage, une partie rectangulaire allongée dont l'extrémité libre est repliée vers l'extérieur pour former la collerette, la partie rectangulaire étant roulée pour former un conduit.According to a constructive detail, each female connection member is made from a metal strip which is a good conductor of electricity, suitably cut to present at one end of the crimping lugs, an elongated rectangular part whose free end is folded towards the outside to form the flange, the rectangular part being rolled up to form a conduit.

De préférence, la partie rectangulaire allongée comporte des ouvertures au droit de la ligne de pliage de la collerette pour éviter la formation de plis.Preferably, the elongated rectangular part has openings in line with the fold line of the collar to avoid the formation of folds.

Suivant encore un détail constructif, dans la partie rectangulaire est découpée longitudinalement une lame dont l'extrémité libre est cambrée et porte contre la surface interne de la collerette. Ainsi on réalise à l'intérieur du conduit de l'organe de connexion femelle une partie en saillie élastique qui assure lorsque l'organe de connexion mâle est introduit une parfaite liaison électrique.According to yet another constructive detail, in the rectangular part is cut longitudinally a blade whose free end is arched and bears against the internal surface of the collar. Thus there is provided inside the conduit of the female connection member an elastic projecting part which ensures when the male connection member is introduced a perfect electrical connection.

De préférence, la lame est pourvue d'au moins un bossage.Preferably, the blade is provided with at least one boss.

Pour encore améliorer la liaison électrique entre l'organe de connexion mâle et l'organe de connexion femelle, la partie rectangulaire comporte au moins un embouti longitudinal.To further improve the electrical connection between the male connection member and the female connection member, the rectangular part comprises at least one longitudinal stamping.

Suivant une caractéristique constructive, le premier élément de la seconde partie de boîtier comporte, à l'extrémité libre des pattes élastiques, du côté des canaux des saillies présentant du côté de l'ouverture d'introduction des organes de connexion mâles une rampe inclinée terminée par un abrupt.According to a constructive characteristic, the first element of the second housing part comprises, at the free end of the elastic tabs, on the side of the channels of the projections having, on the side of the opening for introducing the male connection members, a completed inclined ramp by an abrupt.

De préférence, la jupe du second élément de la seconde partie de boîtier présente au moins une surface inclinée de manière que lors de l'introduction du premier élément dans le second élément les pattes élastiques tendent à être sollicitées en direction des organes de connexion mâles. Ainsi, on réalise un parfait verrouillage de connexion mâle dans le canal correspondant du premier élément de la seconde partie de boîtier.Preferably, the skirt of the second element of the second housing part has at least one inclined surface so that when the first element is introduced into the second element the elastic tabs tend to be urged towards the male connection members. Thus, a perfect male connection locking is achieved in the corresponding channel of the first element of the second housing part.

De préférence, chaque organe de connexion mâle est réalisé à partir d'une bande métallique convenablement découpée pour présenter, à une extrémité, des pattes de sertissage et, à l'autre extrémité, une partie rectangulaire, entre ces deux parties s'étendant deux bandes latérales, la partie rectangulaire étant roulée pour former le barreau, tandis que les bandes latérales sont repliées à l'extérieur pour former le collet.Preferably, each male connection member is produced from a metal strip suitably cut to present, at one end, crimping lugs and, at the other end, a rectangular part, between these two parts extending two side bands, the rectangular part being rolled up to form the bar, while the side bands are folded outside to form the collar.

Enfin, le premier élément de la seconde partie de boîtier comporte sur deux côtés opposés des ergots de verrouillage, tandis que le second élément de ladite seconde partie de boîtier est pourvue de trous destinés à recevoir lesdits ergots moyennant une déformation élastique. Ainsi, lorsque le premier élément et le second élément de la seconde partie de boîtier sont assemblés, ils sont verrouillés et ne peuvent être détachés intempestivement.Finally, the first element of the second housing part has on two opposite sides locking lugs, while the second element of said second housing part is provided with holes intended to receive said lugs by means of elastic deformation. Thus, when the first element and the second element of the second housing part are assembled, they are locked and cannot be untimely detached.

Dans chaque canal 7 est disposé sur une paroi interne une saillie 23 comportant du côté de l'ouverture d'introduction une rampe 23a et de l'autre côté un abrupt 23b.In each channel 7 is arranged on an internal wall a projection 23 comprising on the side of the introduction opening a ramp 23a and on the other side a steep 23b.

L'ouverture 27 est bordée par deux butées 24 dont les extrémités libres sont en forme d'arc et disposées sur un cercle ayant un diamètre sensiblement correspondant à celui de l'organe mâle 6.The opening 27 is bordered by two stops 24, the free ends of which are in the shape of an arc and arranged on a circle having a diameter substantially corresponding to that of the male member 6.

Dans les parois de l'élément 1 correspondant à chaque canal 7 et qui sont opposées à celles pourvues des saillies 23 sont pratiquées des fentes 31 qui déterminent des pattes élastiques 29, celles-ci comportant sur leur face externe une nervure longitudinale 30 et sur leur face interne une saillie 33 conformée pour présenter du côté de l'ouverture 26 une rampe 33a et du côté de l'ouverture 27 un abrupt 33b.In the walls of element 1 corresponding to each channel 7 and which are opposite to those provided with projections 23, slots 31 are formed which determine elastic tabs 29, these having on their external face a longitudinal rib 30 and on their internal face a projection 33 shaped to present on the side of the opening 26 a ramp 33a and on the side of the opening 27 a steep 33b.

Les abrupts 33b et 23b sont situés dans un même plan perpendiculaire à l'axe longitudinal des canaux 7 et à une certaine distance des butées 24.The steep 33b and 23b are located in the same plane perpendicular to the longitudinal axis of the channels 7 and at a certain distance from the stops 24.

L'organe de connexion femelle 3 est représenté en détail aux figures 9 à 12 et est réalisé à partir d'une plaque métallique bonne conductrice de l'électricité et présentant une certaine élasticité.The female connection member 3 is shown in detail in FIGS. 9 to 12 and is produced from a metal plate which is good conductor of electricity and has a certain elasticity.

L'organe 3 est découpé pour présenter deux pattes de sertissage 42 d'un conducteur électrique, deux pattes de sertissage 43 de la gaine isolante du conducteur électrique, une partie rectangulaire allongée 50 dont un petit côté 47 opposé aux pattes de sertissage 43 est légèrement évasé.The member 3 is cut to present two crimping tabs 42 of an electrical conductor, two crimping tabs 43 of the insulating sheath of the electrical conductor, an elongated rectangular part 50 of which a small side 47 opposite to the crimping tabs 43 is slightly flared.

Dans la partie 50 est pratiquée une ouverture 49 dans laquelle s'étend une lame 40 pourvue d'un bossage 48, ladite partie 50 comportant des emboutis longitudinaux 41, et la lame 40 étant cambrée à son extrémité 46.In the part 50, an opening 49 is made in which a blade 40 provided with a boss 48 extends, said part 50 comprising longitudinal stampings 41, and the blade 40 being bent at its end 46.

L'organe de connexion femelle 3 (voir figures 10, 11 et 12) est réalisé en repliant vers l'extérieur l'extrémité 47 pour former une collerette 51. L'ensemble est ensuite roulé (voir figure 12) afin de former un conduit 52.The female connection member 3 (see FIGS. 10, 11 and 12) is produced by folding the end 47 outwards to form a flange 51. The assembly is then rolled (see FIG. 12) in order to form a conduit 52.

La partie cambrée 46 vient porter contre la collerette 51 de sorte que la lame 40 est légèrement en saillie dans le conduit 52.The arched part 46 comes to bear against the collar 51 so that the blade 40 is slightly projecting in the duct 52.

Comme on le voit aux figures 2, 3 et 4, l'organe de connexion 3 reçoit un conducteur 55 qui est serti entre les pattes 42 et dont la gaine isolante 56 est enserrée entre les pattes 43, ledit organe étant engagé dans un canal 7 afin que la collerette 51 vienne porter contre les butées 24, tandis que les abrupts 23b et 33b viennent coopérer avec l'extrémité 47.As seen in Figures 2, 3 and 4, the connection member 3 receives a conductor 55 which is crimped between the tabs 42 and whose insulating sheath 56 is clamped between the legs 43, said member being engaged in a channel 7 so that the collar 51 comes to bear against the stops 24, while the steep 23b and 33b cooperate with the end 47.

Ainsi les organes de connexion femelles 3 sont maintenus dans les canaux 7. L'élément de boîtier 1 est ensuite engagé dans l'élément de boîtier 2 jusqu'à ce que les ergots 10 s'insèrent dans les trous 18. L'engagement des ergots 10 s'effectue moyennant une légère déformation élastique des éléments de boîtier 1 et 2 et est facilité par les rampes inclinées 10a. Lorsque les ergots sont verrouilés les deux éléments de boîtier 1 et 2 ne peuvent plus être séparés.Thus, the female connection members 3 are held in the channels 7. The housing element 1 is then engaged in the housing element 2 until the pins 10 are inserted into the holes 18. The engagement of the pins 10 is carried out by means of a slight elastic deformation of the housing elements 1 and 2 and is facilitated by the inclined ramps 10a. When the lugs are locked the two housing elements 1 and 2 can no longer be separated.

La nervure 30 des pattes 29 peut avoir une hauteur telle que lorsque l'élément 1 est engagé dans l'élément 2 les pattes 29 sont sollicitées pour être déplacées en direction des parois pourvues des saillies 23 de sorte que les organes 3 sont parfaitement verrouillés dans les canaux 7.The rib 30 of the legs 29 can have a height such that when the element 1 is engaged in the element 2 the legs 29 are urged to be moved in the direction of the walls provided with the projections 23 so that the members 3 are perfectly locked in channels 7.

Afin d'éviter la formation de plis le long de la ligne de pliage de la collerette 51, on peut prévoir des petites fentes ou ouvertures 53.In order to avoid the formation of folds along the fold line of the flange 51, small slots or openings 53 can be provided.

L'élément de boîtier 5 est formé d'un corps en matière plastique moulé présentant une série de canaux 60 destinés à recevoir chacun un organe mâle 6, chaque canal 60 comportant une ouverture d'introduction 61 de l'organe 6 et une paroi d'extrémité 63 percée d'un trou 62 à travers lequel s'insère ledit organe 6.The housing element 5 is formed by a molded plastic body having a series of channels 60 each intended to receive a male member 6, each channel 60 comprising an opening 61 for introducing the member 6 and a wall d end 63 pierced with a hole 62 through which said member 6 is inserted.

Chaque canal 60 comporte une ouverture 64 au voisinage de la paroi d'extrémité 63 et ledit élément de boîtier 5 est réalisé afin de présenter pour chaque canal 60 une patte élastique 65 dont l'extrémité libre comporte sur sa face interne une saillie 66 avec une rampe inclinée 66a et un abrupt 66b. En regard de chaque patte élastique 65, il est prévu une saillie 67.Each channel 60 has an opening 64 in the vicinity of the end wall 63 and said housing element 5 is produced in order to present for each channel 60 an elastic tab 65 whose free end has a projection 66 on its internal face with a inclined ramp 66a and an abrupt 66b. Opposite each elastic tab 65, a projection 67 is provided.

L'élément de boîtier 5 sur deux côtés opposés est pourvu d'un ergot 68 avec une rampe 68a et un abrupt 68b.The housing element 5 on two opposite sides is provided with a lug 68 with a ramp 68a and a steep 68b.

L'organe de connexion électrique mâle 6 est représenté en détail aux figures 14 à 17. Cet organe est réalisé à partir d'une bande métallique, bonne conductrice de l'électricité et découpée pour présenter une partie terminale rectangulaire 71 dont une extrémité 75 présente un bord découpé avec des fentes 76, tandis que l'autre extrémité présente deux bandes latérales 72, des pattes de sertissage 73 et 74 étant prévues après les bandes latérales 72.The male electrical connection member 6 is shown in detail in FIGS. 14 to 17. This member is produced from a metal strip, good conductor of electricity and cut to present a rectangular end portion 71 of which one end 75 has an edge cut with slots 76, while the other end has two lateral bands 72, crimping lugs 73 and 74 being provided after the lateral bands 72.

Comme le montre les figures 15 et 16, l'organe est réalisé en roulant la partie 71 afin d'obtenir un barreau cylindrique avec une extrémité libre arrondie. Les bandes latérales 72 sont repliées à l'extérieur du barreau pour former un collet 78 dont une extrémité est légèrement évasée.As shown in Figures 15 and 16, the member is made by rolling the part 71 in order to obtain a cylindrical bar with a rounded free end. The lateral bands 72 are folded back outside the bar to form a collar 78, one end of which is slightly flared.

Entre les pattes 73 est serti un conducteur 80 dont la gaine 81 est enserrée entre les pattes 74. L'organe 6 est engagé dans un canal correspondant 60 et traverse par sa partie terminale le trou 62 et vient buter contre la paroi d'extrémité 63, par l'extrémité correspondant du collet 78, tandis que l'autre extrémité évasée de celui-ci est retenu par l'abrupt 66b de la saillie 66. Il est prévu des moyens de détrompage afin que l'élément de boîtier 5 ne puisse être engagé dans la jupe 96 que suivant une position déterminée.Between the legs 73 is crimped a conductor 80, the sheath 81 of which is clamped between the legs 74. The member 6 is engaged in a corresponding channel 60 and passes through its end portion the hole 62 and abuts against the end wall 63 , by the corresponding end of the collar 78, while the other flared end of the latter is retained by the abrupt 66b of the projection 66. There are provided polarization means so that the housing element 5 cannot be engaged in the skirt 96 only in a determined position.

L'élément de boîtier 4 (voir figures 1, 6 et 7) comprend une cloison interne 84 percée de trous 85 destinés à être traversés par les parties terminales des organes mâles 6, d'un côté de cette cloison s'étendant une jupe 86 dont les dimensions internes correspondent aux dimensions externes de l'élément 5. Cette jupe 86 comporte deux côtés opposés 90 pourvus de trous 87 correspondant aux ergots 68, tandis que les deux autres côtés 91 comportent une partie 92 légèrement plus étroite, adjacente à la cloison 84 et correspondant aux parties de l'élément 5 pourvu des ouvertures 64. Les côtés 91 vont en s'évasant vers l'extrémité libre de la jupe 86.The housing element 4 (see FIGS. 1, 6 and 7) comprises an internal partition 84 pierced with holes 85 intended to be traversed by the end parts of the male members 6, on one side of this partition extending a skirt 86 whose internal dimensions correspond to the external dimensions of the element 5. This skirt 86 has two opposite sides 90 provided with holes 87 corresponding to the lugs 68, while the other two sides 91 have a slightly narrower part 92, adjacent to the partition 84 and corresponding to the parts of the element 5 provided with the openings 64. The sides 91 widen towards the free end of the skirt 86.

Lorsqu'on insère l'élément 5 dans la jupe 86 de l'élément 4, les parois inclinées 91 de celle-ci tendent à presser les pattes 65 contre les organges mâles 6 de sorte qu'on est assuré du verrouillage desdits organes dans les canaux 60.When the element 5 is inserted into the skirt 86 of the element 4, the inclined walls 91 of the latter tend to press the legs 65 against the male oranges 6 so that one is assured of the locking of said organs in the channels 60.

Du côté opposé à la jupe 86, l'élément de boîtier 4 est prolongé par une jupe 95 dont les dimensions internes correspondent aux dimensions externes de l'élément 2 de manière recevoir celui-ci. La jupe 95 est pourvue sur une paroi 96 d'un trou 97 destiné à recevoir le verrou 20. Il est prévu des moyens de détrompage afin que les éléments 2 et 4 ne puissent être assemblés que dans une seule position.On the side opposite to the skirt 86, the housing element 4 is extended by a skirt 95 whose internal dimensions correspond to the external dimensions of the element 2 so as to receive the latter. The skirt 95 is provided on a wall 96 with a hole 97 intended to receive the latch 20. There are provided polarizing means so that the elements 2 and 4 can only be assembled in one position.

Le connecteur peut facilement être ouvert, il suffit d'appuyer sur le bouton 22 pour dégager le verrou 20 de l'ouverture 97, les éléments 2 et 4 pouvant ainsi être séparés.The connector can easily be opened, it suffices to press the button 22 to release the lock 20 from the opening 97, the elements 2 and 4 can thus be separated.

La lame 40 et les emboutis 41 forment des parties en saillie à l'intérieur du conduit de l'organe femelle 3, de sorte que l'organe mâle 6 s'engage légèrement à force et qu'ainsi on est assuré d'une bonne liaison électrique.The blade 40 and the stampings 41 form protruding parts inside the duct of the female member 3, so that the male member 6 engages slightly by force and thus we are assured of good electrical connection.
