Description

La présente invention concerne une grille mobile de protection de contacts broches dans un connecteur électrique. Elle concerne aussi le connecteur équipé de cette grille.The present invention relates to a mobile grid for protecting pin contacts in an electrical connector. It also concerns the connector fitted with this grid.

Les connecteurs, notamment dans l'automobile, doivent être de plus en plus légers, de moins en moins encombrants et à broches multiples. Ceci est essentiellement dû au fait que le nombre nécessaire de connexions électriques dans les véhicules augmente de façon très importante.Connectors, especially in the automobile, must be increasingly lighter, less bulky and multi-pin. this is essentially due to the fact that the necessary number of electrical connections in vehicles increases very significantly.

Ainsi les contacts sont de faibles dimensions et les diamètres sont couramment inférieurs au millimètre, une taille courante de contact broche est 0,64 mm.So the contacts are small and the diameters are commonly less than one millimeter, a common pin contact size is 0.64 mm.

Il se pose alors un problème lors de l'accouplement des boítiers de connecteur, engendré par la fragilité mécanique de ces contacts. Le moindre désalignement conduit à une non-connexion. De toutes les façons, compte tenu de la longueur de ces contacts, lors de d'introduction, sous l'effort d'insertion, il peut se produire un flambage.There is then a problem when coupling the housings of connector, generated by the mechanical fragility of these contacts. The least misalignment leads to a non-connection. Either way, count given the length of these contacts, during insertion, under stress insertion, buckling may occur.

Il faut aussi pouvoir protéger ces contacts broches des éventuels accès durant la manipulation du boítier.It is also necessary to be able to protect these pin contacts from possible access. during the handling of the case.

Une solution avantageuse consiste à disposer une grille mobile de protection sur le connecteur portant les contacts broches, grille qui peut prendre une position avancée de protection des broches de contact avant emboítement des deux parties du boítier et une position reculée, dégageant les broches de contact pour permettre leur accouplement avec les contacts femelles portés par un boítier de connecteur complémentaire, simultanément à cet accouplement.An advantageous solution consists in having a movable grid of protection on the connector carrying the pin contacts, grid which can take an advanced position to protect the front contact pins fitting of the two parts of the case and a retracted position, releasing the contact pins to allow their coupling with the contacts females carried by a complementary connector housing, simultaneously with this coupling.

Dans ce domaine, on connaít le brevet US-A-4 797 116 qui décrit un boítier de connexion dans lequel, le connecteur mâle muni de broches comprend une grille de protection. Cette grille peut également prendre une position avancée et une position reculée. Cette grille possède deux bras munis chacun d'un ergot prévu pour coopérer avec le connecteur femelle associé.In this area, we know US-A-4,797,116 which describes a connection box in which the male connector provided with pins includes a protective grid. This grid can also take a forward position and a retracted position. This grid has two arms provided each of a lug provided to cooperate with the associated female connector.

Dans une première étape, ces bras assurent la liaison et l'immobilisation de la grille de protection par rapport au connecteur femelle. A cet effet, les bras comportent à l'avant des ergots adaptés pour venir s'encliqueter dans des logements ménagés dans le connecteur complémentaire.In a first step, these arms ensure the connection and immobilization of the protective grid with respect to the female connector. To this end, the arms have lugs at the front adapted to snap into housings in the complementary connector.

Dans cette position, le contact mâle est verrouillé dans son alvéole par la grille qui est équipée de coins qui viennent en butée derrière des bras élastiques de verrouillage des contacts.In this position, the male contact is locked in its socket by the grid which is fitted with corners which abut behind arms contact locking elastics.

De même, les contacts femelles sont immobilisés dans leur alvéole et maintenus en place par des ergots adaptés.Likewise, the female contacts are immobilized in their socket and held in place by suitable lugs.

Ensuite, au cours de l'accouplement complet, la grille est immobilisée par rapport au connecteur femelle et les contacts du connecteur mâle pénètrent dans les contacts femelles du connecteur femelle en passant à travers la grille.Then, during full mating, the grid is immobilized relative to female connector and male connector contacts penetrate the female contacts of the female connector passing to through the gate.

Lors du désaccouplement des deux connecteurs, le connecteur mâle est retiré, la grille restant immobile par rapport au connecteur femelle se déplace en translation par rapport au connecteur mâle, la ramenant dans sa position initiale.When the two connectors are uncoupled, the male connector is removed, the grid remains stationary relative to the female connector moves in translation relative to the male connector, bringing it back to its position initial.

Un tel agencement pose plusieurs problèmes.Such an arrangement poses several problems.

Lors du désaccouplement, le verrouillage secondaire des contacts mâles est désactivé, si bien que si la traction est effectuée en tout ou partie sur les fils, un ou plusieurs contacts mâles peuvent être extraits de leurs alvéoles respectifs.During uncoupling, the secondary locking of the male contacts is deactivated, so that all or part of the traction on the wires, one or more male contacts can be extracted from their alveoli respectively.

De plus, les bras et les ergots prennent beaucoup de place dans le connecteur et augmentent l'encombrement. D'ailleurs l'exemple représenté montre un boítier de connexion à deux broches. In addition, the arms and lugs take up a lot of space in the connector and increase the size. Besides the example shown shows a two-pin connection box.

Or le but de la présente invention est aussi de permettre une application à des boítiers de connexion à plusieurs dizaines de contacts broches.The object of the present invention is also to allow an application to connection boxes with several dozen pin contacts.

On connaít aussi de l'art antérieur le brevet US-A- 5 558 526 qui décrit un connecteur avec une grille mobile qui est maintenue en place par des bras élastiques qui doivent être écartés pour permettre les mouvements de la grille. Il est aussi prévu des moyens de verrouillage.We also know from the prior art US-A-5,558,526 which describes a connector with a movable grid which is held in place by arms elastics which must be spread to allow the movements of the grid. Locking means are also provided.

La présente invention a pour but de proposer une grille mobile de protection qui est indépendante des verrouillages des contacts, qui comprend des moyens de verrouillage et de manoeuvre peu encombrants et totalement intégrés dans le volume dudit connecteur, répartis entre le boítier du connecteur et la grille elle-même, qui est montée par simple emboítement et encliquetage sans nécessiter une étape de montage d'organes spécifiques de verrouillage, et qui peut être directement venue de moulage.The present invention aims to provide a movable grid of protection which is independent of contact locks, which includes space-saving and totally space-saving locking and operating means integrated into the volume of said connector, distributed between the housing of the connector and the grid itself, which is fitted by simple fitting and snap-in without requiring a step of mounting specific organs of locking, and which may have come directly from molding.

A cet effet, la présente invention propose une grille mobile de protection de broches, associée à un connecteur électrique porte-broches adapté pour coopérer par emboítement avec un connecteur électrique porte-contacts femelles muni d'une grille fixe, ladite grille mobile de protection pouvant prendre deux positions l'une avancée de protection des broches et l'autre reculée de libération des broches, caractérisée en ce que cette grille mobile comprend un linguet mobile prévu pour coopérer avec une première butée du connecteur électrique porte-broches dans une position avancée et pour s'escamoter afin de libérer ladite grille mobile qui peut prendre une position reculée et en ce que la grille fixe comprend un linguet extracteur adapté pour coopérer avec ce linguet mobile pendant les mouvements de la position reculée de la grille mobile vers la position avancée.To this end, the present invention provides a movable grid of protection of pins, associated with an electrical connector pin holder adapted to cooperate by interlocking with an electrical contact-holder connector females fitted with a fixed grid, said mobile protective grid can take two positions, one advanced pin protection and the other spindle release distance, characterized in that this grid mobile comprises a movable latch designed to cooperate with a first stop of the electrical connector pin holder in an advanced position and to retract in order to release said movable grid which can take a retracted position and in that the fixed grid includes an extractor latch adapted to cooperate with this movable latch during the movements of the retracted position of the movable grid towards the advanced position.

De plus, la grille fixe comprend également une tige de commande adaptée pour assurer le désengagement du linguet mobile de la première butée.In addition, the fixed grid also includes a control rod. adapted to ensure the disengagement of the movable latch from the first stop.

Le linguet mobile comprend une tête munie d'un premier ergot latéral à section triangulaire en sorte de former une rampe. The movable latch comprises a head provided with a first lateral lug with triangular section so as to form a ramp.

Quant au linguet extracteur, selon une caractéristique particulière, il porte à son extrémité supérieure une tête d'extraction dont la section est triangulaire et forme une rampe dans le sens de connexion.As for the extractor latch, according to a particular characteristic, it carries at its upper end an extraction head whose section is triangular and forms a ramp in the direction of connection.

Selon un mode de réalisation particulier, la tige de commande comprend une came adaptée pour coopérer avec une seconde butée fixe portée par le connecteur porte-broches et un actionneur étudié pour assurer le désengagement du linguet mobile de la première butée, de la position avancée vers la position reculée.According to a particular embodiment, the control rod comprises a cam adapted to cooperate with a second fixed stop carried by the pin holder connector and an actuator designed to ensure the disengagement of the movable latch from the first stop, from the advanced position to the backward position.

Selon une disposition avantageuse, l'actionneur et la came sont décalés en hauteur par rapport à l'aile.According to an advantageous arrangement, the actuator and the cam are offset in height with respect to the wing.

L'invention couvre aussi le connecteur électrique qui comprend une telle grille mobile de protection.The invention also covers the electrical connector which comprises a such a mobile protection grid.

De façon préférentielle, les moyens de positionnement comportent trois systèmes identiques, deux latéraux et un frontal.Preferably, the positioning means comprise three identical systems, two lateral and one frontal.

Sur la figure 1, on a représenté un connecteur 10 porte-contacts femelles prévu pour venir coopérer par emboítement avec un connecteur 12 porte-broches. Des moyens 14 de verrouillage à étrier permettent de rendre sûre cette liaison après emboítement.In Figure 1, there is shown a connector 10 contact carrier females provided to come cooperate by fitting with a connector 12 pin holder. Caliper locking means 14 make it possible to make secure this connection after interlocking.

Le connecteur porte-contacts femelles reçoit une grille 16 fixe qui pour des raisons pratiques de fabrication et notamment de simplification de moulage est réalisée indépendamment. Cette grille est ensuite rapportée par encliquetage sur le connecteur grâce à des moyens 18 d'encliquetage.The female contact-holder connector receives a fixed grid 16 which for practical manufacturing reasons and in particular the simplification of molding is carried out independently. This grid is then reported by latching on the connector by means of latching means 18.

Un joint 20 d'étanchéité, périphérique vient se loger dans un évidemment ménagé dans ce connecteur porte-contacts femelles en sorte d'assurer une étanchéité de la liaison du connecteur porte-broches avec le connecteur porte-contacts femelles.A peripheral seal 20 is housed in a obviously made in this female contact holder connector so sealing the connection of the pin holder connector with the female contact carrier connector.

Il est prévu un module 22 porte-broches adapté pour être rapporté dans ce connecteur porte-broches.There is provided a module 22 for pin holders adapted to be attached in this pin holder connector.

Selon la présente invention, l'ensemble représenté est complété par une grille 24 mobile de protection des broches du connecteur porte-broches.According to the present invention, the assembly shown is completed by a movable grille 24 for protecting the pins of the pin holder connector.

Les différents organes constitutifs et fonctionnels de cet ensemble de deux connecteurs sont maintenant décrits en détail en regard des différentes figures annexées.The different constituent and functional organs of this set of two connectors are now described in detail with regard to the different attached figures.

Sur la figure 2A, on a référencé le boítier 26 proprement dit avec les rampes 28 des moyens 14 de verrouillage à étrier. In FIG. 2A, reference has been made to the housing 26 proper with the ramps 28 of the stirrup locking means 14.

Dans ce boítier est introduit le module 22 porte-broches qui y est solidarisé par encliquetage. Des pattes élastiques 30, visibles sur la figure 1, sont venues de moulage à cet effet et coopèrent avec ledit boítier.In this box is introduced the module 22 pin holder which is there secured by snap-fastening. Elastic tabs 30, visible in FIG. 1, came from molding for this purpose and cooperate with said housing.

Sur cette même figure, la grille 24 mobile de protection est représentée en détail.In this same figure, the mobile protective grid 24 is shown in detail.

Cette grille 24 comprend des passages 32 prévus pour laisser passer les broches 34 du module porte-broches ainsi que cela est montré en détail sur la figure 2B.This grid 24 includes passages 32 provided for letting the pins 34 of the pin holder module as shown in detail on the Figure 2B.

Il est aussi ménagé, également venues de moulage, des pattes élastiques 36 avec des crans 38 de retenue, prévus pour coopérer avec le module porte-contacts.It is also spared, also molded, legs elastic 36 with retaining notches 38, provided to cooperate with the contact carrier module.

Sur cette figure 2A et surtout 2B, on note la présence de moyens 40 de positionnement de la grille représentée en position avancée de protection des broches 34.In this figure 2A and especially 2B, we note the presence of means 40 for positioning of the grid shown in the advanced protection position pins 34.

Ces moyens sont composés tout d'abord d'un linguet 42 mobile avec une tête 44. Plus particulièrement, dans le mode de réalisation préférentiel retenu, on note que les moyens 40 de positionnement comportent trois systèmes identiques, deux latéraux et un frontal.These means are firstly composed of a movable latch 42 with a head 44. More particularly, in the preferred embodiment retained, we note that the positioning means 40 include three identical systems, two lateral and one frontal.

Chaque linguet est solidaire de la grille, en pied. Plus particulièrement dans le mode de réalisation retenu, la tête 44 comprend un premier ergot 46 latéral, de section sensiblement triangulaire formant une rampe d'introduction et un second ergot latéral 48.Each latch is integral with the grid, at the bottom. More specifically in the selected embodiment, the head 44 comprises a first lug 46 lateral, of substantially triangular section forming an introduction ramp and a second lateral lug 48.

Dans la position avancée de la grille mobile, celle des figures 2A et 2B, on note que le premier ergot 46 est plaqué contre la paroi du boítier 26 du connecteur porte-broches tandis que le second ergot 48 est espacé de cette même paroi, libérant un passage 50.In the advanced position of the movable grid, that of FIGS. 2A and 2B, we note that the first lug 46 is pressed against the wall of the housing 26 of the spindle connector while the second lug 48 is spaced from this same wall, freeing a passage 50.

Ces moyens 40 de positionnement comprennent de plus une première et une seconde butée 52 et 54, fixes, solidaires de la paroi du boítier 26 du connecteur 12 porte-broches.These positioning means 40 further comprise a first and a second stop 52 and 54, fixed, integral with the wall of the housing 26 of the 12 pin holder connector.

La première butée 52 a également une section triangulaire, sensiblement identique à celle du premier ergot 46, mais cette première butée est orientée dans le sens contraire, formant une retenue à l'introduction. L'ensemble des deux éléments, premier ergot et première butée, forme une double rampe dans la position avancée de la grille de protection représentée sur les figures 2A et 2B.The first stop 52 also has a triangular section, substantially identical to that of the first lug 46, but this first stop is oriented in the opposite direction, forming a reserve upon introduction. All of the two elements, first lug and first stop, form a double ramp in the advanced position of the protective grid shown in FIGS. 2A and 2B.

Le connecteur 10 porte-contacts femelles reçoit la grille 16 fixe et l'ensemble monté, y compris le joint 20 d'étanchéité, est représenté sur la figure 3A.The connector 10 female contact carrier receives the fixed grid 16 and the assembled assembly, including the seal 20, is shown in the Figure 3A.

Cette grille 16 comprend également les logements de réception des contacts femelles et de passage des broches mâles lors de la connexion des deux connecteurs.This grid 16 also includes the housing for receiving female contacts and male pin passage when connecting the two connectors.

Des moyens 56 de manoeuvre et d'extraction sont portés par cette même grille 16 fixe. Ces moyens de manoeuvre comprennent également deux systèmes latéraux et un système frontal pour coopérer avec les systèmes 40 de positionnement, chacun comportant une tige 58 de commande et un linguet 60 extracteur. On décrit un système latéral mais les références portées pour le système frontal sont identiques pour les mêmes organes.Means 56 for maneuvering and extraction are carried by this same fixed grid 16. These maneuvering means also include two lateral systems and a frontal system to cooperate with 40 systems positioning, each comprising a control rod 58 and a latch 60 extractor. We describe a lateral system but the references carried for the frontal system are identical for the same organs.

La tige 58 de commande présente un corps 62 déformable et une tête 64 équipée d'une came 65 et d'un actionneur 66. Le corps est déformable mais dans un seul plan, sensiblement parallèle à celui de la paroi latérale de la grille dans laquelle il est encastré.The control rod 58 has a deformable body 62 and a head 64 fitted with a cam 65 and an actuator 66. The body is deformable but in a single plane, substantially parallel to that of the side wall of the grid in which it is embedded.

Le linguet 60 extracteur est composé d'un corps 68 souple, flexible dans un plan sensiblement perpendiculaire à la paroi latérale de la grille dans laquelle il est encastré. Le linguet porte à son extrémité supérieure une tête 70 d'extraction dont la section est triangulaire et forme une rampe dans le sens de connexion et qui présente un déport formant une aile 72.The catch 60 extractor is composed of a body 68 flexible, flexible in a plane substantially perpendicular to the side wall of the grid in which it is embedded. The latch has a head at its upper end 70 extraction whose section is triangular and forms a ramp in the direction of connection and which has an offset forming a wing 72.

On note un décalage en hauteur entre cette aile 72 et l'ensemble came 65 et actionneur 66.There is an offset in height between this wing 72 and the cam assembly 65 and actuator 66.

En ce qui concerne le système frontal, la seule différence est que le corps 62 déformable travaille dans un plan parallèle à celui du linguet 60 extracteur car on dispose de plus d'espace.As far as the frontal system is concerned, the only difference is that the deformable body 62 works in a plane parallel to that of the latch 60 extractor because there is more space.

Le fonctionnement et les mouvements des différents organes de cet agencement sont maintenant décrits en regard des figures 5A à 5F. The functioning and movements of the different organs of this arrangement are now described with reference to FIGS. 5A to 5F.

Sur la figure 5A, la position représentée est la position initiale dans laquelle la grille 24 mobile de protection est encliquetée dans le boítier 26 du connecteur 12 porte-broches. Cette grille est alors immobilisée en position avancée dans laquelle les broches sont protégées. Le linguet 42 mobile de cette grille a son premier ergot 46 en appui sur la première butée 52 fixe, solidaire de la paroi du boítier 26 du connecteur 12 porte-broches. La grille ne peut être retirée car les pattes élastiques 36 avec leurs crans 38 de retenue coopèrent avec le module 22 porte-contacts.In FIG. 5A, the position represented is the initial position in which the movable protective grid 24 is snapped into the housing 26 of the 12 pin holder connector. This grid is then immobilized in position advanced in which the pins are protected. The movable latch 42 of this grid has its first lug 46 bearing on the first fixed stop 52, secured to the wall of the housing 26 of the connector 12 pin holder. The grid does can be removed because the elastic tabs 36 with their retaining notches 38 cooperate with the module 22 contact carrier.

Lors de l'accouplement des deux connecteurs, la grille 16 fixe du connecteur 10 porte-contacts femelles vient actionner certains organes de la grille mobile de protection.When the two connectors are coupled, the fixed grid 16 of the connector 10 female contact carrier actuates certain organs of the mobile protection grid.

Ainsi sur la figure 5B, le linguet 60 extracteur, par sa tête 70 et plus particulièrement par son aile 72 attaque la rampe formée par le premier ergot 46 du linguet mobile qui assure le soulèvement de ce dernier avec flexion du corps 68. On note que simultanément, la tige 58 de commande n'est pas encore entrée en contact avec le boítier 26.Thus in FIG. 5B, the retaining latch 60, by its head 70 and more particularly by its wing 72 attacks the ramp formed by the first lug 46 of the movable latch which raises the latter with bending of the body 68. Note that simultaneously, the control rod 58 is not still come into contact with the housing 26.

En faisant progresser l'accouplement, la came 65 de la tige 58 de commande vient en appui sur la seconde butée 54 fixe, solidaire de la paroi du boítier 26 du connecteur 12 porte-broches. C'est l'étape représentée sur la figure 5C.By advancing the coupling, the cam 65 of the rod 58 of control comes to bear on the second fixed stop 54, integral with the wall of the housing 26 of the 12 pin holder connector. This is the step shown on the Figure 5C.

Parallèlement, la tête 70 du linguet extracteur glisse sur la rampe constituée par la première butée 52.At the same time, the head 70 of the extractor latch slides on the ramp constituted by the first stop 52.

Sur la figure 5D, l'actionneur 66 de la tige de commande vient se glisser dans l'espace 50 laissé libre entre le second ergot 48 latéral de la tête du linguet mobile car la came en appui sur la seconde butée 54 assure la flexion de la tige de commande. Ceci provoque le désengagement du premier ergot 46 de la première butée 52. Simultanément, la tête 70 du linguet extracteur passe au-delà de la double rampe 46/52 et le corps 68 de ce linguet reprend sa forme initiale.In FIG. 5D, the actuator 66 of the control rod comes to slide in the space 50 left free between the second lug 48 lateral to the head of the movable latch because the cam bearing on the second stop 54 ensures the bending of the control rod. This causes the first lug 46 to disengage of the first stop 52. Simultaneously, the head 70 of the extractor latch passes beyond the double ramp 46/52 and the body 68 of this latch resumes its initial form.

La grille fixe 16 est alors au contact de la grille 24 mobile de protection et donc libérée pour un mouvement en translation. The fixed grid 16 is then in contact with the mobile protective grid 24 and therefore released for movement in translation.

Lorsque la translation pour l'accouplement est poursuivie plus avant, ce que montrent les figures 5E et 5F, la grille 16 fixe se déplace conjointement en translation avec la grille de protection. Les broches pénètrent dans les contacts femelles, ce qui n'est pas représenté car bien connu de tous les accouplements électriques. Sur la figure 5F, la grille 24 mobile de protection est en position reculée totale et l'accouplement sont finalisé.When the translation for mating is continued further, this that FIGS. 5E and 5F show, the fixed grid 16 moves jointly in translation with the protective grid. The pins enter the female contacts, which is not shown as well known to all electrical couplings. In FIG. 5F, the mobile protective grid 24 is in full retracted position and the coupling is finalized.

En ce qui concerne le désaccouplement, les étapes sont différentes ce qui oblige à une description détaillée en regard des figures 6A à 6D.Regarding uncoupling, the steps are different. which requires a detailed description with reference to FIGS. 6A to 6D.

Le connecteur 10 porte-contacts femelles est déplacé en translation par rapport au connecteur 12 porte-broches et la grille 16 fixe se déplace conjointement avec le connecteur 10 porte-contacts femelles.The connector 10 female contact carrier is moved in translation by relative to the 12 pin holder connector and the fixed grid 16 moves together with the connector 10 female contact carrier.

Lors de la première étape, figure 6A, le recul de la grille fixe est tel que l'aile 72 du linguet extracteur vient au contact du premier ergot 46 et la came 65 vient en appui sur la seconde butée 54 du boítier 26.During the first step, FIG. 6A, the recoil of the fixed grid is such that the wing 72 of the extractor latch comes into contact with the first lug 46 and the cam 65 comes to bear on the second stop 54 of the housing 26.

Lorsque la translation est poursuivie, tel que cela est indiqué sur la figure 6B, la tige 58 de commande fléchit mais le décalage en hauteur est tel que l'actionneur 66 ne vient pas attaquer le linguet 42 mobile.When the translation is continued, as indicated on the FIG. 6B, the control rod 58 flexes but the height offset is such that the actuator 66 does not come to attack the movable latch 42.

Par contre, la tête 70 par son aile 72 assure l'entraínement en translation de la grille 24 mobile de protection vers la position avancée. Le premier ergot 46 et cette aile 72 attaquent la rampe constituée par la première butée 52 fixe sans provoquer de désengagement du couple « aile 72 / premier ergot 46 ».By cons, the head 70 by its wing 72 provides training in translation of the movable protective grid 24 towards the advanced position. The first lug 46 and this wing 72 attack the ramp formed by the first stop 52 fixed without causing disengagement of the couple "wing 72 / first lug 46 ".

Dès que le premier ergot 46 passe au-delà de la première butée 52 fixe, l'élasticité du linguet 42 mobile provoque la mise au taquet derrière cette même butée constituant à nouveau une double rampe sur laquelle glisse l'aile 72 du linguet extracteur. La grille 24 mobile de protection est de nouveau immobilisée en position avancée.As soon as the first lug 46 passes beyond the first fixed stop 52, the elasticity of the movable latch 42 causes the cleat behind this same stop again constituting a double ramp on which the wing slides 72 of the extractor latch. The mobile protective grid 24 is again immobilized in the forward position.

La tige de commande reste inactive dans cette phase de désaccouplement.The control rod remains inactive during this phase of uncoupling.

La dernière phase est le déplacement de l'aile 72 du linguet 42 mobile sur le premier ergot 46, maintenant bloqué. The last phase is the displacement of the wing 72 of the movable latch 42 on the first lug 46, now blocked.

Sur la figure 4, on a représenté une variante dans laquelle le linguet extracteur vient attaquer une butée 54-1 qui provoque le soulèvement direct de la tête du linguet mobile dans un plan perpendiculaire au boítier 26 du connecteur 12 porte-broches.FIG. 4 shows a variant in which the latch extractor attacks a stop 54-1 which causes direct lifting of the movable latch head in a plane perpendicular to the housing 26 of the 12 pin holder connector.

Ainsi, la grille de protection peut prendre automatiquement une position avancée de protection et une position reculée de libération des broches au cours de l'accouplement des deux connecteurs.Thus, the protective grid can automatically take a position advanced protection and a remote pin release position at during the coupling of the two connectors.

Le retour de la grille en position de protection lors du désaccouplement est transparent pour l'opérateur et ne demande aucune manipulation particulière supplémentaire.Return of the grid to the protective position during uncoupling is transparent to the operator and requires no manipulation particular extra.
