Description

L'invention vise un connecteur électrique.The invention relates to an electrical connector.

L'invention se rapporte à un connecteur comprenant un corps en matière isolante présentant des rangées de canaux dans chacun desquels est introduit un organe de contact électrique mâle ou femelle serti, à une extrémité, d'un conducteur électrique.The invention relates to a connector comprising a body of insulating material having rows of channels in each of which is inserted a male or female electrical contact member set at one end with an electrical conductor.

Dans la technique antérieure (Voir brevet GB-A-2 186 748 et brevet DE-A-43 25 371), on connaît de tels connecteurs qui comportent une clé de verrouillage qui est formée d'un élément en forme de U à partir de l'âme duquel s'érigent une série de barreaux correspondant aux rangées de canaux, le corps en matière isolante comportant des fentes s'étendant perpendiculairement aux canaux et dans lesquelles s'insèrent les barreaux qui ainsi portent contre un épaulement des organes de contact électrique pour s'opposer au retrait intempestif de ceux-ci.In the prior art (See patent GB-A-2 186 748 and patent DE-A-43 25 371), such connectors are known which include a locking key which is formed from a U-shaped element from the core of which is erected a series of bars corresponding to the rows of channels, the body of insulating material comprising slots extending perpendicular to the channels and into which the bars are inserted which thus bear against a shoulder of the electrical contact members to oppose the untimely withdrawal of these.

Les différents connecteurs présentent un certain nombre d'inconvénients. Si on désire que ceux-ci comportent des organes de contacts électriques différents, c'est-à-dire permettant des liaisons électriques ayant des intensités différentes, on sait prévoir des éléments de boîtiers complexes et des clés également complexes ce qui conduit à grever le prix de tels connecteurs.Different connectors have a number of drawbacks. If it is desired that these include different electrical contact members, that is to say allowing electrical connections having different intensities, it is known to provide complex housing elements and also complex keys, which leads to encumbering the price of such connectors.

De plus, la complexité des formes se prête mal à la réalisation de connecteurs présentant des dimensions très réduites.In addition, the complexity of the forms lends itself poorly to the production of connectors having very small dimensions.

Un premier but de l'invention est de remédier à cet inconvénient.A first object of the invention is to remedy this drawback.

Le connecteur électrique, selon l'invention, est du type comprenant un corps en matière isolante présentant une série de canaux disposés par rangées parallèles et destinés à recevoir, chacun, un organe de contact électrique mâle ou femelle serti, à une extrémité, d'un conducteur et présentant, en un point intermédiaire de la longueur, un épaulement, ledit corps comportant, d'une part, des fentes dans les parois séparant les rangées de canaux et, d'autre part, des conduites ménagées au voisinage de deux parois opposées, une clé de verrouillage des organes de contact étant prévue et formée d'un élément en forme de U avec deux branches destinées à s'insérer dans les conduits et une âme à partir de laquelle s'érigent une série de barreaux parallèles destinés à s'insérer dans les fentes et à coopérer avec les épaulements des organes de contact électrique pour bloquer ceux-ci dans les canaux, caractérisé en ce que les fentes s'étendent perpendiculairement aux axes des canaux depuis l'un des conduits destinés à recevoir une branche de la clé jusqu'à l'autre conduit destiné à recevoir l'autre branche, de manière à former dans chaque paroi séparant les rangées de canaux, deux lèvres, les barreaux étant profilés pour présenter, d'une part, au moins une nervure tournée du côté de l'une des lèvres, celle-ci comportant une rainure correspondante, et, d'autre part, des bords débordant en saillie dans les canaux de deux rangées voisines.The electrical connector according to the invention is of the type comprising a body of insulating material having a series of channels arranged in parallel rows and intended to each receive a male or female electrical contact member crimped at one end with a conductor and having, at an intermediate point of the length, a shoulder, said body comprising, on the one hand, slots in the walls separating the rows of channels and, on the other hand, conduits formed in the vicinity of two walls opposite, a key for locking the contact members being provided and formed of a U-shaped element with two branches intended to be inserted in the conduits and a core from which a series of parallel bars are erected intended to insert into the slots and cooperate with the shoulders of the electrical contact members to lock them in the channels, characterized in that the slots extend perpendicular stretching the axes of the channels from one of the conduits intended to receive a branch of the key to the other conduit intended to receive the other branch, so as to form in each wall separating the rows of channels, two lips, the bars being profiled so as to present, on the one hand, at least one rib turned towards the side of one of the lips, the latter comprising a corresponding groove, and, on the other hand, projecting edges projecting into the channels of two adjacent rows.

Grâce à cette disposition, on réalise un connecteur d'une structure simple, les barreaux étant tous identiques, les canaux pouvant être agencés pour recevoir des organes de contacts électriques ayant des dimensions différentes mais présentant tous, à la même hauteur, une même partie amincie afin de s'insérer dans les parties séparant les barreaux.Thanks to this arrangement, a connector of a simple structure is produced, the bars all being identical, the channels being able to be arranged to receive electrical contact members having different dimensions but all having, at the same height, the same thinned part. in order to fit into the parts separating the bars.

Suivant une caractéristique constructive particulière, les nervures sont disposées du côté tourné vers les épaulements des organes de contacts électriques, les bords débordant en saillie dans les canaux de deux rangées voisins étant ménagés de part et d'autre des nervures.According to a particular constructive characteristic, the ribs are arranged on the side facing the shoulders of the electrical contact members, the projecting edges projecting into the channels of two neighboring rows being provided on either side of the ribs.

De plus, dans les connecteurs de très petites dimensions, la liaison entre la lèvre et le barreau offre une bonne résistance mécanique qui, ainsi, s'oppose au fléchissement du barreau même si une traction importante est effectuée pour arracher un organe de contact électrique.In addition, in very small connectors, the connection between the lip and the bar offers good mechanical resistance which, in this way, opposes the bending of the bar even if significant traction is applied to tear off an electrical contact member.

Comme les barreaux se trouvent ainsi renforcés, la clé ne peut être mise en place que si tous les organes de contacts électriques sont parfaitement mis en place.As the bars are thus reinforced, the key can only be put in place if all the electrical contact members are perfectly in place.

Comme les canaux sont disposés par rangées et que la clé se met en place parallèlement aux rangées, la course d'insertion de ladite clé est importante ce qui permet de parfaitement vérifier la mise en place des organes de contact électrique.As the channels are arranged in rows and the key is put in place parallel to the rows, the insertion stroke of said key is important, which makes it possible to perfectly check the installation of the electrical contact members.

On a également constaté que souvent, au montage, les clés sont perdues. Un second but de l'invention est de remédier à cet inconvénient. A cet effet, les branches comportent, chacune, sur leur face externe, un ergot coulissant dans une lumière des parois correspondantes du corps.It has also been found that often during assembly, the keys are lost. A second object of the invention is to remedy this drawback. To this end, the branches each have, on their outer face, a lug sliding in a lumen of the corresponding walls of the body.

Ainsi, les clés restent solidaires des corps des connecteurs ce qui permet également de faciliter le montage des organes de contact électrique dans ceux-ci.Thus, the keys remain integral with the bodies of the connectors, which also makes it easier to mount the electrical contact members therein.

Suivant une caractéristique constructive particulière, les branches comportent, latéralement au voisinage de leur extrémité libre sur chaque bord, un bossage, tandis que dans les conduits, au voisinage des extrémités, sont ménagés des crans avec lesquels coopèrent les bossages, les crans situés au voisinage d'une extrémité correspondant à une position d'attente de la clé, tandis que les crans, situés au voisinage de l'autre extrémité, correspondent à une position de verrouillage de la clé.According to a particular constructive characteristic, the branches comprise, laterally in the vicinity of their free end on each edge, a boss, while in the conduits, in the vicinity of the ends, notches are formed with which the bosses cooperate, the notches located in the vicinity a corresponding end to a waiting position for the key, while the notches, located in the vicinity of the other end, correspond to a locking position of the key.

Afin d'augmenter l'élasticité des branches au droit des bossages, chaque branche au droit des bossages comporte une ouverture allongée.In order to increase the elasticity of the branches in line with the bosses, each branch in line with the bosses has an elongated opening.

Le connecteur, selon l'invention, peut être destiné à s'insérer dans la jupe d'un élément complémentaire, le corps comportant un logement dans lequel s'engage, en position de verrouillage, l'âme de la clé.The connector according to the invention may be intended to be inserted into the skirt of a complementary element, the body comprising a housing in which engages, in the locked position, the core of the key.

Ainsi, la clé est parfaitement maintenue et ne peut se déverrouiller lorsque le corps est logé dans la jupe et, de plus, ladite clé s'oppose à l'assemblage du corps et de l'élément complémentaire si la clé n'est pas en position de verrouillage, position qu'elle ne peut, bien entendu, occuper que si tous les organes de contact électrique sont parfaitement mis en place dans les canaux.Thus, the key is perfectly maintained and can not be unlocked when the body is housed in the skirt and, moreover, said key opposes the assembly of the body and the complementary element if the key is not in locking position, position which it can, of course, occupy only if all the electrical contact members are perfectly positioned in the channels.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels :The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the accompanying drawings, in which:

Les figures 1 et 2 montrent en perspective une clé désignée dans son ensemble par la référence 1 et destinée à être utilisée avec un boîtier 20 d'un connecteur.Figures 1 and 2 show in perspective a key designated as a whole by the reference 1 and intended for use with a housing 20 of a connector.

La clé est constituée par un élément en forme de U avec deux branches 2 et 3 et une âme 4.The key consists of a U-shaped element with two branches 2 and 3 and a core 4.

Chaque branche 2 et 3 comporte, sur sa face externe au voisinage de son extrémité libre, un ergot de retenue 5 qui, du côté opposé à ladite extrémité libre, présente un abrupt 5a.Each branch 2 and 3 comprises, on its external face in the vicinity of its free end, a retaining lug 5 which, on the side opposite to said free end, has a steep 5a.

Chaque branche 2 et 3 présente, le long de chaque bord longitudinal et au voisinage de l'extrémité libre, un bossage 6 et, au droit de chaque bossage, une ouverture allongée 7 afin que chaque bossage 6 puisse s'effacer élastiquement.Each branch 2 and 3 has, along each longitudinal edge and in the vicinity of the free end, a boss 6 and, to the right of each boss, an elongated opening 7 so that each boss 6 can be elastically erased.

A partir de la surface interne de l'âme 4 et parallèlement aux branches 2 et 3 s'étendent une série de barreaux 8, chaque barreau affectant une section rectangulaire avec deux petits côtés 8a et 8b et deux grands côtés 8c et 8d, le grand côté 8c présentant une nervure médiane longitudinale 9, les angles des petits côtés 8a et 8b adjacents au grand côté 8d sont rognés pour former des pans coupés 11.From the internal surface of the core 4 and parallel to the branches 2 and 3 extend a series of bars 8, each bar affecting a rectangular section with two short sides 8a and 8b and two large sides 8c and 8d, the large side 8c with a midrib longitudinal 9, the angles of the short sides 8a and 8b adjacent to the long side 8d are cropped to form cut sides 11.

La face interne de la branche 2 comporte une protubérance 14 parallèle aux barreaux 8 et située dans un même plan que ceux-ci, l'une des faces de cette protubérance 14 présentant un pan coupé 15 correspondant aux pans coupés 11.The internal face of the branch 2 comprises a protuberance 14 parallel to the bars 8 and situated in the same plane as the latter, one of the faces of this protuberance 14 having a cutaway 15 corresponding to the cut sides 11.

La face interne de la branche 3 est également pourvue d'une protubérance 14 avec un pan coupé 15.The internal face of the branch 3 is also provided with a protuberance 14 with a cutaway 15.

Le boîtier 20 du connecteur est formé d'un corps sensiblement parallélépipédique percé d'une série de canaux 17 et 18 destinés à recevoir, chacun, un organe 21 de connexion électrique.The housing 20 of the connector is formed of a substantially parallelepiped body pierced with a series of channels 17 and 18 intended to each receive a member 21 for electrical connection.

A la figure 3 on a représenté, à plus grande échelle, l'organe 21, celui-ci étant constitué d'un corps allongé réalisé en une matière bonne conductrice de l'électricité présentant, à une extrémité, une pince élastique 23 destinée à enserrer un organe mâle complémentaire et, à l'autre extrémité, des pattes de sertissage 24 et 25 pour enserrer un conducteur électrique. Le corps présente un épaulement 27 qui est raccordé à la partie pourvue des pattes 24 et 25 par une partie étroite 26 terminée par un léger épanouissement 28.In Figure 3 there is shown, on a larger scale, the member 21, the latter consisting of an elongated body made of a material good conductor of electricity having, at one end, an elastic clamp 23 intended for enclose a complementary male member and, at the other end, crimping tabs 24 and 25 to enclose an electrical conductor. The body has a shoulder 27 which is connected to the part provided with lugs 24 and 25 by a narrow part 26 ending in a slight opening 28.

L'organe 21 peut avoir plusieurs dimensions suivant l'intensité des courants électriques qui doivent le traverser, par contre, la partie étroite 26, quelles que soient les dimensions des organes, reste la même ainsi que la distance séparant l'épaulement 27 de l'extrémité libre.The member 21 can have several dimensions depending on the intensity of the electric currents which must pass through it, on the other hand, the narrow part 26, whatever the dimensions of the members, remains the same as well as the distance separating the shoulder 27 from the 'free end.

Les canaux 17 reçoivent des organes 21 ayant des dimensions supérieures à ceux introduits dans les canaux 18.The channels 17 receive members 21 having dimensions greater than those introduced into the channels 18.

Chaque canal 17 et 18 comporte, à une extrémité, une ouverture 30 par laquelle est introduit un organe 21 et, à l'autre extrémité, un épaulement 31 de retenue dudit organe 21 avec une fente 32.Each channel 17 and 18 has, at one end, an opening 30 through which a member 21 is introduced and, at the other end, a shoulder 31 for retaining said member 21 with a slot 32.

Le boîtier 20 est destiné à s'insérer dans une jupe 35 d'un élément femelle 38 dans le fond duquel s'érigent des organes mâles 36 destinés à traverser les fentes 32 pour s'insérer dans les pinces élastiques 23.The housing 20 is intended to be inserted in a skirt 35 of a female element 38 in the bottom of which erect male members 36 intended to pass through the slots 32 to be inserted in the elastic clamps 23.

Le boîtier 20 comporte deux conduits 35 et 36 destinés à recevoir respectivement les branches 2 et 3, chaque conduit présentant une lumière 37 dans chacune desquelles coulisse l'ergot correspondant 5. Ainsi, la clé peut coulisser librement dans les conduits du boîtier, mais ne peut être désolidarisée de celui-ci.The housing 20 comprises two conduits 35 and 36 intended to receive the branches 2 and 3 respectively, each conduit having a slot 37 in each of which slides the corresponding lug 5. Thus, the key can slide freely in the conduits of the housing, but does not can be separated from it.

Dans chaque conduit 35 et 36, sur deux parois opposées 39 et 40, sont ménagés des premiers crans 41 correspondant à un calage de la clé dans une position de pré-verrouillage et des seconds crans 42 correspondant à une position de verrouillage de la clé. Les bossages 6 pouvant s'insérer dans les crans 41 ou 42 moyennant une légère déformation élastique, déformation facilitée par les lumières 7.In each conduit 35 and 36, on two opposite walls 39 and 40, are provided first notches 41 corresponding to a setting of the key in a pre-locking position and second notches 42 corresponding to a locking position of the key. The bosses 6 which can be inserted in the notches 41 or 42 by means of a slight elastic deformation, deformation facilitated by the slots 7.

Entre les crans 41 et 42, dans les parois 39 et 40, sont ménagées des rainures 43 et 44 respectivement, dans lesquelles s'insèrent les bossages 6.Between the notches 41 and 42, in the walls 39 and 40, grooves 43 and 44 are formed respectively, into which the bosses 6 are inserted.

Les canaux 17 et 18 sont disposés par séries alignées parallèlement, chaque série étant séparée de la série adjacente par une paroi 46, la face 8c des barreaux 8, du côté des épaulements 31 débordant sur deux rangées voisines de canaux 17, 18.The channels 17 and 18 are arranged in series aligned in parallel, each series being separated from the adjacent series by a wall 46, the face 8c of the bars 8, on the side of the shoulders 31 projecting over two adjacent rows of channels 17, 18.

Dans les parois 46, parallèlement aux conduits 35 et 36, sont pratiquées des fentes 48, avec des lèvres 52 et 53, et, dans les parois adjacentes aux conduits 35 et 36, des fentes 50. Les fentes 48 s'étendent depuis le conduit 35 jusqu'au conduit 36.In the walls 46, parallel to the conduits 35 and 36, slots 48 are formed, with lips 52 and 53, and, in the walls adjacent to the conduits 35 and 36, slots 50. The slots 48 extend from the conduit 35 to conduit 36.

La lèvre 53 des fentes 48 comporte une rainure 54 destinée au guidage de la nervure 9.The lip 53 of the slots 48 has a groove 54 intended for guiding the rib 9.

Les protubérances 14 s'insèrent dans les fentes 50.The protrusions 14 are inserted into the slots 50.

Le boîtier 20 comporte, à une extrémité, un logement 55 dans lequel s'insère l'extrémité de la clé 1 avec l'âme 4 de manière, lorsque ladite clé occupe la position de verrouillage, qu'elle ne fasse pas saillie à la surface dudit boîtier.The housing 20 comprises, at one end, a housing 55 into which the end of the key 1 is inserted with the core 4 so that, when said key occupies the locking position, that it does not protrude at the surface of said housing.

Comme on le voit à la figure 14 les barreaux 8, par leurs petits côtés 8b, font saillie dans les canaux 17 d'une première rangée et par leurs petits côtés 8a dans les canaux d'une rangée adjacente à ladite première rangée. Ainsi, les grands côtés 8c viennent coopérer avec les épaulements 27 pour s'opposer au retrait des organes 21 lorsqu'ils sont logés dans les canaux 17, tandis que les pans coupés 11 permettent aux épanouissements 28 de se loger.As can be seen in FIG. 14, the bars 8, by their short sides 8b, project into the channels 17 of a first row and by their short sides 8a into the channels of a row adjacent to said first row. Thus, the long sides 8c cooperate with the shoulders 27 to oppose the withdrawal of the members 21 when they are housed in the channels 17, while the cut sides 11 allow the openings 28 to be housed.

On conçoit que si un organe 21 n'est pas correctement mis en place, le barreau 8 butera contre celui-ci et la clé 1 ne pourra pas être enfoncée jusqu'à sa position de verrouillage (voir figures 7, 8, 9 et 10).It will be understood that if a member 21 is not correctly put in place, the bar 8 will abut against it and the key 1 cannot be pressed into its locking position (see FIGS. 7, 8, 9 and 10 ).

Comme les barreaux 8, par leur nervure 9, coopèrent avec la rainure 54, lesdits barreaux font pratiquement partie intégrante du connecteur et s'opposent à l'arrachement intempestif des organes 21.As the bars 8, by their rib 9, cooperate with the groove 54, said bars are practically an integral part of the connector and oppose the untimely tearing of the members 21.

Dans le mode de réalisation représenté, les organes de contact électrique 21 sont femelles, mais bien entendu, ceux-ci pourraient être mâles.In the embodiment shown, the electrical contact members 21 are female, but of course, these could be male.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et représenté. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the embodiment which has just been described and shown. Many detailed modifications can be made without departing from the scope of the invention.
