DE 92 13118 U1 discloses a multicontact connector housing arranged to be mounted, preferably removably, on a carrier, the housing comprising:
  • a housing body having at least one fixing portion adapted to cooperate with the support when the housing is mounted on this support,
    the housing according to the present invention comprises:
  • at least one locking element movable relative to the housing body between an unlocked position and a locked position in which the locking element bears on the support when the housing is mounted on said support, the locking element approaching of said fixing portion of the housing body as it moves from the unlocked position to the locked position, the locking element comprising at least one elastically deformable tab adapted to be applied to a first abutment of the housing body when the locking element is in the unlocked position,
  • at least one resilient return member arranged to move the locking member from the unlocked position to the locked position.

Le montage du boîtier de connecteur sur le support peut ainsi être relativement simple.Mounting the connector housing on the support can thus be relatively simple.

Dans un exemple de mise en oeuvre de l'invention, l'élément de verrouillage est monté de manière coulissante sur le corps de boîtier.In an exemplary implementation of the invention, the locking member is slidably mounted on the housing body.

Avantageusement, le corps de boîtier et l'élément de verrouillage forment un logement recevant l'organe de rappel élastique.Advantageously, the housing body and the locking element form a housing receiving the resilient return member.

De préférence, le corps de boîtier comporte une deuxième butée sur laquelle la patte élastiquement déformable peut s'appliquer pour limiter la course de l'élément de verrouillage lorsque celui-ci est déplacé sur une course au-delà de la position verrouillée.Preferably, the housing body comprises a second stop on which the elastically deformable tab can be applied to limit the stroke of the locking element when the latter is moved on a stroke beyond the locked position.

Ainsi, l'élément de verrouillage reste solidaire du corps de boîtier et l'on réduit, voire supprime, le risque d'égarer une ou plusieurs pièces constitutives du boîtier de connecteur.Thus, the locking element remains integral with the housing body and it reduces or even eliminates the risk of misplacing one or more component parts of the connector housing.

Le boîtier 1 présente en outre un logement 16 destiné à recevoir un bloc isolant pour la fixation d'éléments de contact électrique, ce logement 16 étant perpendiculaire à l'axe X et s'étendant au-dessus de la base 5, comme illustré sur la figure 1.The housing 1 further has a housing 16 for receiving an insulating block for fixing electrical contact elements, this housing 16 being perpendicular to the X axis and extending above the base 5, as shown in FIG. the figure 1 .

Le boîtier 1 comporte un renfoncement longitudinal 17 s'étendant suivant l'axe X depuis le logement 16 jusque dans une portion d'attache pour câbles 18 faisant saillie à l'arrière du boîtier 1.The housing 1 has a longitudinal recess 17 extending along the X axis from the housing 16 into a cable attachment portion 18 protruding from the rear of the housing 1.

La portion d'attache 18 est agencée pour permettre d'attacher des câbles à cette portion, comme on le verra par la suite.The attachment portion 18 is arranged to allow cables to be attached to this portion, as will be seen later.

Cette portion d'attache 18 présente une section transversale sensiblement en U.This attachment portion 18 has a substantially U-shaped cross section.

Le logement 16 est défini par deux parois latérales 20 sur chacune desquelles sont réalisées deux zones de verrouillage 21.The housing 16 is defined by two lateral walls 20 on each of which two locking zones 21 are formed.

Comme illustré sur la figure 6, chaque zone de verrouillage 21 comporte une série de dents 22 perpendiculaires à un axe Y, les dents de chaque série étant régulièrement espacées, les deux zones de verrouillage 21 étant séparées l'une de l'autre par un espace ayant une première hauteur h1 mesurée suivant l'axe Y.As illustrated on the figure 6 each locking zone 21 comprises a series of teeth 22 perpendicular to a Y axis, the teeth of each series being regularly spaced apart, the two locking zones 21 being separated from each other by a space having a first height h 1 measured along the Y axis.

Dans l'exemple considéré, les deux zones de verrouillage 21 d'une face latérale 20 sont différentes l'une de l'autre, les dents 22 présentant par exemple une longueur différente.In the example, the two locking zones 21 of a side face 20 are different from each other, the teeth 22 having for example a different length.

En variante, les zones 21 peuvent être toutes identiques.Alternatively, the zones 21 may all be identical.

Les zones de verrouillage 21 d'une face latérale 20 sont symétriques des zones 21 sur l'autre face latérale 20 par rapport à un plan passant par les axes X et Y.The locking zones 21 of a lateral face 20 are symmetrical with the zones 21 on the other lateral face 20 with respect to a plane passing through the X and Y axes.

Le boîtier 1 comporte sur chaque face latérale 20 deux éléments de blocage en relief 24, formés dans l'exemple considéré chacun par un picot, dont le rôle sera expliqué plus loin.The housing 1 comprises on each side face 20 two relief locking elements 24, formed in the example each considered by a pin, whose role will be explained later.

Le boîtier 1 comporte en outre un élément de verrouillage 30 monté de manière coulissante sur la base 5 du corps de boîtier 3.The housing 1 further comprises a locking member 30 slidably mounted on the base 5 of the housing body 3.

Dans l'exemple considéré, l'élément de verrouillage 30 est réalisé en matière plastique, de préférence d'un seul tenant.In the example considered, the locking element 30 is made of plastic material, preferably in one piece.

L'élément de verrouillage 30 comporte deux nervures 31 parallèles destinées à s'engager de manière coulissante dans les rainures 9 correspondantes de la base 5, comme illustré sur la figure 5.The locking member 30 has two parallel ribs 31 for slidingly engaging the corresponding grooves 9 in the base 5, as shown in FIG. figure 5 .

L'élément de verrouillage 30 présente en outre une surface de repérage 32 sensiblement plane.The locking element 30 further has a substantially planar registration surface 32.

L'élément de verrouillage 30 forme avec la base 5 un logement 34 destiné à recevoir un organe de rappel élastique 35, comme illustré sur les figures 3 et 4.The locking element 30 forms with the base 5 a housing 34 intended to receive an elastic return member 35, as illustrated in FIGS. Figures 3 and 4 .

Dans l'exemple considéré, l'organe de rappel élastique 35 est constitué par un ressort hélicoïdal.In the example considered, the elastic return member 35 is constituted by a helical spring.

L'organe de rappel élastique 35 s'applique à une extrémité sur l'élément de verrouillage 30 et à l'extrémité opposée sur le corps de boîtier 3.The elastic return member 35 is applied at one end to the locking element 30 and at the opposite end to the housing body 3.

L'élément de verrouillage 30 comporte une partie d'actionnement 36 pourvue d'une fente 37, cette partie d'actionnement 36 offrant une prise à un utilisateur pour déplacer, à l'aide d'un outil tel qu'un tournevis, l'élément de verrouillage 30 contre l'effort exercé par l'organe de rappel élastique 35.The locking element 30 has an actuating portion 36 provided with a slot 37, this actuating portion 36 providing a grip for a user to move, using a tool such as a screwdriver, the locking element 30 against the force exerted by the resilient return member 35.

L'élément de verrouillage 30 comporte, à l'opposé de la partie d'actionnement 36, une patte élastiquement déformable 38 agencée pour s'appliquer sur une première butée 39 du corps de boîtier 3 lorsque l'élément de verrouillage 30 est dans une position déverrouillée, comme illustré sur la figure 3.The locking element 30 has, opposite the actuating part 36, an elastically deformable tab 38 arranged to be applied on a first abutment 39 of the casing body 3 when the locking element 30 is in a unlocked position, as shown on the figure 3 .

La première butée 39 est réalisée par exemple sur le dessous de la base 5 du corps de boîtier 3.The first stop 39 is made for example on the underside of the base 5 of the casing body 3.

L'élément de verrouillage 30 comporte en outre un bouton 40 se raccordant à la patte élastiquement déformable 38, le bouton 40 définissant une surface d'appui 41 permettant à un utilisateur d'exercer, notamment à l'aide d'un doigt, une force sur la patte élastiquement déformable en vue de désengager celle-ci de la première butée 39.The locking element 30 further comprises a button 40 connected to the elastically deformable tab 38, the button 40 defining a bearing surface 41 allowing a user to exercise, in particular with the aid of a finger, a force on the elastically deformable tab to disengage it from the first stop 39.

Le bouton 40 s'étend à travers une fente 44 réalisée sur la base 5 du corps de boîtier 3.The button 40 extends through a slot 44 made on the base 5 of the casing body 3.

Le corps de boîtier 3 présente en outre une deuxième butée 43 réalisée sur le dessous de la base 5 et sur laquelle la patte élastiquement déformable 38 peut s'appliquer pour limiter la course de l'élément de verrouillage 30 lorsque celui-ci est désengagé de la première butée 39 et le boîtier de connecteur 1 est non assemblé avec le support 2.The housing body 3 further has a second stop 43 made on the underside of the base 5 and on which the elastically deformable tab 38 can be applied to limit the stroke of the locking element 30 when the latter is disengaged from the first stop 39 and the connector housing 1 is unassembled with the support 2.

Ainsi, on évite que l'élément de verrouillage 30 puisse être séparé du corps de boîtier 3, lorsque le boîtier de connecteur 1 est non utilisé, étant par exemple stocké avant l'utilisation.Thus, it is avoided that the locking element 30 can be separated from the housing body 3, when the connector housing 1 is not used, being for example stored before use.

L'élément de verrouillage 30 présente une rainure 46 s'étendant perpendiculairement à l'axe X et agencé pour coopérer avec le support 2 lorsque l'élément de verrouillage est dans une position verrouillée, comme illustré sur la figure 4.The locking element 30 has a groove 46 extending perpendicularly to the X axis and arranged to cooperate with the support 2 when the locking element is in a locked position, as shown in FIG. figure 4 .

La surface de repérage 10 du corps de boîtier 3 et celle 32 de l'élément de verrouillage 30 s'étendent sensiblement dans la continuité l'une de l'autre lorsque l'élément de verrouillage 30 est en position verrouillée, comme illustré sur les figures 4 et 5.The registration surface 10 of the housing body 3 and that of the locking element 30 extend substantially in continuity with one another when the locking element 30 is in the locked position, as illustrated in FIGS. Figures 4 and 5 .

En revanche, lorsque l'élément de verrouillage 30 est en position déverrouillée, en appui sur la première butée 39, ou a parcouru une course au-delà de la position de verrouillage, étant en appui sur la deuxième butée 43, les surfaces de repérage 10 et 32 sont décalées l'une par rapport à l'autre suivant l'axe X.On the other hand, when the locking element 30 is in the unlocked position, resting on the first stop 39, or has traveled a stroke beyond the locking position, bearing on the second stop 43, the marking surfaces 10 and 32 are offset relative to each other along the X axis.

Ainsi, l'utilisateur peut vérifier visuellement si l'élément de verrouillage 30 est dans une position correcte de verrouillage, le cas échéant.Thus, the user can visually check whether the locking member 30 is in a proper locking position, if any.

On va maintenant décrire plus en détail le support 2.We will now describe in more detail the support 2.

Le support 2 présente une forme longitudinale suivant un axe Z, perpendiculaire à l'axe X.The support 2 has a longitudinal shape along an axis Z, perpendicular to the axis X.

Le support 2 présente en section transversale, perpendiculaire à l'axe Z, une portion centrale 50 ayant une forme sensiblement en U et deux portions en bordure 51, de part et d'autre de cette portion centrale 50, ces portions en bordure 51 s'étendant dans un plan défini par les axes X et Z.The support 2 has in cross section, perpendicular to the axis Z, a central portion 50 having a substantially U-shaped and two portions at the edge 51, on either side of this central portion 50, these edge portions 51 s extending in a plane defined by the X and Z axes.

Ces portions 51 définissent des bords parallèles 52 parallèles à l'axe Z et présentent des encoches 53 régulièrement espacées sur chaque bord 52, ces encoches 53 servant d'éléments d'indexation lors du montage du boîtier 1 sur le support 2.These portions 51 define parallel edges 52 parallel to the Z axis and have notches 53 regularly spaced on each edge 52, these notches 53 serving as indexing elements when mounting the housing 1 on the support 2.

Dans l'exemple considéré, le support 2 est réalisé en métal.In the example considered, the support 2 is made of metal.

Comme on peut le voir sur la figure 4, lorsque l'élément de verrouillage 30 est dans la position verrouillée, la rainure 46 s'engage sur la portion en bordure 51 du support 2, grâce à la force exercée par l'organe de rappel élastique 35 sur l'élément de verrouillage 30.As can be seen on the figure 4 when the locking element 30 is in the locked position, the groove 46 engages the edge portion 51 of the support 2, due to the force exerted by the elastic return member 35 on the locking member 30 .

Le boîtier de connecteur 1 est ainsi maintenu sur le support 2, d'une part, grâce à l'élément de verrouillage 30 en prise avec une portion en bordure 51 du support 2 et, d'autre part, grâce aux pattes 7 en prise avec l'autre portion en bordure 51, comme illustré sur la figure 2.The connector housing 1 is thus held on the support 2, on the one hand, thanks to the locking element 30 in engagement with an edge portion 51 of the support 2 and, on the other hand, thanks to the bracketed tabs 7 with the other portion at the edge 51, as illustrated on the figure 2 .

Ces pattes 7 peuvent être légèrement élastiquement déformables, afin de s'appliquer avec une contrainte résiduelle sur la portion en bordure 51 du support 2.These tabs 7 may be slightly elastically deformable, so as to apply with a residual stress on the edge portion 51 of the support 2.

Ainsi, il est possible d'établir un ancrage mécanique efficace du boîtier 1 sur le support 2 tout en permettant une liaison électrique satisfaisante entre le support 2 et le boîtier de connecteur 1.Thus, it is possible to establish an effective mechanical anchoring of the housing 1 on the support 2 while allowing a satisfactory electrical connection between the support 2 and the connector housing 1.

Le boîtier de connecteur 1 peut être assemblé, si on le souhaite, avec un deuxième boîtier de connecteur multicontacts 60, comme illustré sur la figure 6.The connector housing 1 can be assembled, if desired, with a second multicontact connector housing 60, as shown in FIG. figure 6 .

Le deuxième boîtier 60 présente une face de connexion 61 par laquelle le boîtier 60 est assemblé avec le boîtier 1.The second housing 60 has a connection face 61 through which the housing 60 is assembled with the housing 1.

Le deuxième boîtier 60 comporte un corps de boîtier 62 et un capot de verrouillage 63 mobile par rapport au corps de boîtier 62 parallèlement à l'axe Y, entre une position déverrouillée et une position verrouillée.The second housing 60 includes a housing body 62 and a locking hood 63 movable relative to the housing body 62 parallel to the Y axis between an unlocked position and a locked position.

Le capot de verrouillage 63 comprend deux paires de pattes élastiquement déformables 65 pourvues chacune d'une zone de verrouillage 66 avec une série de dents 67 perpendiculaires à l'axe Y.The locking cover 63 comprises two pairs of elastically deformable tabs 65 each provided with a locking zone 66 with a series of teeth 67 perpendicular to the Y axis.

Les dents 67 de chaque série sont régulièrement espacées, chaque zone de verrouillage 66 d'une patte élastiquement déformable 65 étant destinée à coopérer avec une zone de verrouillage 21 du boîtier 1 lorsque les deux boîtiers 1 et 60 sont assemblés et le capot de verrouillage 63 est dans la position verrouillée.The teeth 67 of each series are regularly spaced, each locking zone 66 of an elastically deformable tab 65 being intended to cooperate with a locking zone 21 of the housing 1 when the two housings 1 and 60 are assembled and the locking cap 63 is in the locked position.

Les zones de verrouillage 66 du deuxième boîtier 60 sont séparées l'une de l'autre, suivant l'axe Y, par un espace ayant une deuxième hauteur h2 mesurée suivant cet axe Y, différente de la hauteur h1 précitée.The locking zones 66 of the second housing 60 are separated from each other, along the Y axis, by a space having a second height h 2 measured along this axis Y, different from the height h 1 above.

Dans l'exemple considéré, les séries de dents des zones de verrouillage 21 et 66 sur les boîtiers 1 et 60 présentent toutes le même pas et l'écart entre les première et deuxième hauteurs h1 et h2 est différent d'un multiple du pas des séries de dents.In the example considered, the series of teeth of the locking zones 21 and 66 on the housings 1 and 60 all have the same pitch and the difference between the first and second heights h 1 and h 2 is different from a multiple of no series of teeth.

Dans l'exemple considéré, cet écart entre h1 et h2 est égal à un multiple d'un demi-pas des séries de dents.In the example considered, the difference between h 1 and h 2 is equal to a multiple of half a pitch of the series of teeth.

Par exemple, l'écart h1 est multiple d'un demi-pas des séries de dent et h2 multiple d'un pas des séries de dents.For example, the difference h 1 is a multiple of a half-step of the series of teeth and h 2 multiple of a step of the series of teeth.

En variante, l'écart h1 est multiple d'un pas des séries de dents et h2 multiple d'un demi-pas des séries de dents.In a variant, the difference h 1 is a multiple of one step of the series of teeth and h 2 which is a multiple of a half-step of the series of teeth.

Ce décalage d'un demi-pas permet d'assurer une incrémentation relativement fine lors du verrouillage du capot 63 sur le corps de boîtier 1.This offset of a half-step makes it possible to ensure a relatively fine incrementation during the locking of the cover 63 on the casing body 1.

Dans l'exemple considéré, les pattes 65 sont réalisées chacune dans une fenêtre 69 du capot de verrouillage 63.In the example considered, the tabs 65 are each made in a window 69 of the locking cap 63.

Le capot de verrouillage 63 présente deux paires de fentes 70 dans chacune desquelles un élément de blocage 24 du boîtier 1 peut coulisser lorsque le capot 63 passe de la position déverrouillée vers la position verrouillée, de manière à ce que, lorsque le capot est en position verrouillée, la coopération de l'élément de blocage 24 avec la fente 70 correspondante solidarise les deux boîtiers 1 et 60 ensemble dans la direction X.The locking cover 63 has two pairs of slots 70 in each of which a locking element 24 of the housing 1 can slide when the cover 63 moves from the unlocked position to the locked position, so that when the cover is in position locked, the cooperation of the locking element 24 with the corresponding slot 70 secures the two housings 1 and 60 together in the X direction.

Dans l'exemple considéré, chaque fente 70 présente une forme sensiblement en L.In the example considered, each slot 70 has a shape substantially in L.

Le capot de verrouillage 63 est monté de manière coulissante sur le corps de boîtier 62.The locking cover 63 is slidably mounted on the housing body 62.

A cet effet, le corps de boîtier 62 peut comporter deux rainures de guidage 72 parallèles et dans chacune desquelles peut coulisser un rebord 73 du capot de verrouillage 63, comme illustré sur la figure 8.For this purpose, the housing body 62 may comprise two parallel guide grooves 72 and in each of which can slide a flange 73 of the locking cover 63, as shown in FIG. figure 8 .

Le capot de verrouillage 63 comporte deux pattes élastiquement déformables 74, chacune étant apte à coopérer avec une encoche 75 de guidage réalisée sur le corps de boîtier 62.The locking cover 63 comprises two elastically deformable tabs 74, each being able to cooperate with a guide notch 75 made on the casing body 62.

Dans l'exemple considéré, comme illustré sur la figure 8, le corps de boîtier 62 comporte une portion d'attache pour câbles 18 à l'instar du boîtier 1.In the example considered, as illustrated on the figure 8 , the housing body 62 has a cable tie portion 18 like the housing 1.

L'assemblage des boîtiers 1 et 60 est réalisé de manière relativement simple, en amenant ces deux boîtiers l'un en face de l'autre, engageant les reliefs 24 dans les fentes 70 et en faisant coulisser le capot 63 suivant l'axe Y afin d'immobiliser le capot 63 par rapport au corps de boîtier 62 grâce à la coopération des zones de verrouillage 21 et 66 et celle des éléments de blocage 24 dans les fentes 70.The assembly of the housings 1 and 60 is made in a relatively simple manner, bringing these two housings facing each other, engaging the reliefs 24 in the slots 70 and sliding the cover 63 along the Y axis in order to immobilize the cover 63 with respect to the housing body 62 through the cooperation of the locking zones 21 and 66 and that of the locking elements 24 in the slots 70.

La position verrouillée du capot 63 est illustrée sur la figure 7.The locked position of the hood 63 is illustrated on the figure 7 .

Comme on peut le voir sur cette figure 7, le boîtier de connecteur 60 reçoit un bloc isolant 90 fixé dans le logement 16 et présentant des alvéoles dans lesquelles sont introduits des éléments de contact électrique 91.As we can see on this figure 7 , the connector housing 60 receives an insulating block 90 fixed in the housing 16 and having cells into which electrical contact elements 91 are introduced.

Chaque élément de contact 91 est relié à un câble 92.Each contact element 91 is connected to a cable 92.

Le faisceau de câbles 92 est fixé à la portion d'attache câbles 18 du boîtier 60 à l'aide d'un collier de serrage 93 réalisé en un matériau conducteur, par exemple en métal.The wire harness 92 is fixed to the cable tie portion 18 of the housing 60 by means of a clamping collar 93 made of a conductive material, for example metal.

On peut ainsi obtenir une mise à la masse des câbles 92 avec le corps de boîtier 62, la portion d'attache 18 formant une zone de sortie des câbles 92.It is thus possible to obtain a grounding of the cables 92 with the housing body 62, the fastening portion 18 forming an exit zone of the cables 92.

Comme illustré sur les figures 9 et 10, le boîtier de connecteur 1 peut comporter, si on le souhaite, un capot de blindage 95 réalisé par exemple en métal, en matériau plastique électriquement conducteur ou en matériau plastique avec un revêtement conducteur.As illustrated on Figures 9 and 10 , the connector housing 1 may comprise, if desired, a shielding cap 95 made for example of metal, electrically conductive plastic material or plastic material with a conductive coating.

Le capot de blindage 95 comporte deux bords avant 96 s'étendant parallèlement à l'axe Y et deux bords inférieurs 97 s'étendant parallèlement à l'axe X.The shielding cap 95 has two leading edges 96 extending parallel to the Y axis and two lower edges 97 extending parallel to the X axis.

Le capot de blindage 95 comporte sur ses bords 96 et 97 des pattes élastiquement déformables 98, respectivement 99.The shielding cap 95 has on its edges 96 and 97 elastically deformable tabs 98 and 99, respectively.

Le corps de boîtier 3 comporte des rainures 100 parallèles à l'axe Y et dans lesquelles peuvent s'engager par encliquetage les pattes élastiquement déformables 98 du capot de blindage 95.The housing body 3 has grooves 100 parallel to the Y axis and in which the resiliently deformable tabs 98 of the shielding cap 95 can snap into engagement.

Après assemblage, comme illustré sur la figure 10, les pattes élastiquement déformables 99 viennent s'appliquer sur une face extérieure 102 du corps de boîtier 3.After assembly, as shown on the figure 10 , the elastically deformable tabs 99 are applied on an outer face 102 of the casing body 3.

Le contact des pattes 98 et 99 sur le corps de boîtier 3 assure une continuité de masse ou un blindage satisfaisant entre le capot de blindage 95 et le corps de boîtier 3, sans nécessiter de moyen de serrage supplémentaire entre ces deux éléments.The contact of the tabs 98 and 99 on the casing body 3 ensures satisfactory ground continuity or shielding between the shielding cap 95 and the casing body 3, without the need for additional clamping means between these two elements.

Le capot de blindage 95 comporte une portion arrière 105 présentant une section transversale sensiblement en U, cette portion arrière 105 étant agencée pour coopérer avec la portion d'attache 18 du corps de boîtier 3 afin de former une ouverture tubulaire 106 permettant d'introduire des câbles dans le boîtier, comme illustré sur les figures 9 et 10.The shielding cap 95 comprises a rear portion 105 having a substantially U-shaped cross-section, this rear portion 105 being arranged to cooperate with the fastening portion 18 of the casing body 3 in order to form a tubular opening 106 for introducing cables in the housing, as shown in the Figures 9 and 10 .

La capot de blindage 95 comporte en outre une queue d'accrochage 108 faisant saillie à l'extérieur de l'ouverture tubulaire 106 et agencée pour permettre d'y attacher des câbles sortant de l'ouverture 106, comme illustré sur la figure 11.The shielding cap 95 further includes a hooking tail 108 projecting out of the tubular opening 106 and arranged to allow attachment of cables exiting the opening 106 as shown in FIG. figure 11 .

Le faisceau de câbles 92 peut être fixé à la queue d'accrochage 108 par exemple par l'intermédiaire d'un collier de serrage 110 réalisé en un matériau conducteur, ce collier 110 étant mis en place sur la queue d'accrochage 108.The wire harness 92 may be attached to the attachment shank 108, for example by means of a clamping collar 110 made of a conductive material, this collar 110 being placed on the attachment shank 108.

Ainsi, comme on peut le constater, selon l'utilisation souhaitée, il est possible d'utiliser le capot de blindage 95 ou non.Thus, as can be seen, depending on the desired use, it is possible to use the shielding cover 95 or not.

L'invention offre ainsi une modularité satisfaisante en ce qui concerne l'utilisation des différents éléments du connecteur.The invention thus offers a satisfactory modularity as regards the use of the various elements of the connector.

Comme illustré sur la figure 12, les câbles 92 peuvent être introduits dans une gaine avec une tresse de masse 112 fixée sur la portion d'attache câbles du corps de boîtier et sur la portion arrière du capot de blindage 95.As illustrated on the figure 12 , the cables 92 can be introduced into a sheath with a mass braid 112 fixed on the cable tie portion of the housing body and on the rear portion of the shielding cap 95.

Cette tresse de masse 112 est maintenue par exemple au moyen d'une pièce de serrage 113 rapportée sur cette tresse 112.This mass braid 112 is held for example by means of a clamping piece 113 attached to this braid 112.

Bien entendu, l'invention n'est pas limitée aux exemples de mise en oeuvre qui viennent d'être décrits.Of course, the invention is not limited to the implementation examples which have just been described.

L'une des hauteurs h1 et h2 peut par exemple être nulle, auquel cas deux zones de verrouillage 21 du corps de boîtier 3 peuvent par exemple être adjacentes l'une de l'autre.One of the heights h 1 and h 2 may for example be zero, in which case two locking zones 21 of the housing body 3 may for example be adjacent to each other.
