- the clips and tabs to be coupled are positioned with accuracy and that their correct position can be checked before the connection operation.
- Connectors use primary locks to lock the clips in position in their material case plastic.
- These primary locks are for example fingers which are erased when the clip is inserted into the case and which constitute a rear stop, when the clip is in the correct position, to keep it in this correct position.
- These primary locks are usually arranged inside the case and they are not visible from the outside. If during the clip insertion operation in the case, the clip is not brought to its position correct, the primary lock remains in the cleared position and does not not play its role, without this anomaly being detected from the outside. During a subsequent operation connector coupling, the clip can move back under the tongue pushing and contact may not be made without the operator being aware of it.
- a secondary lock i.e. an additional part, visible from the outside or likely to prevent mechanical coupling of a connector.
- a lock secondary is usually an external part, which must be set up on the housing, and which takes a correct position only if the connector's electrical components are in the correct position.
- these secondary locks are of the slide or drawer type, and they are put in place on the housing during an assembly operation.
- Document WO-96-34429 describes an electrical connector carrying a secondary lock secured to the housing, which has a standby position and a locked position, the locked position cannot be reached that if the electrical contacts are in the correct position, check the locking position by sight or touch.
- One of the aims of the invention is to propose a secondary lock which does not requires no additional parts and assembly operation, one part to avoid the difficulties of this assembly operation, on the other hand to reduce the manufacturing costs of connectors.
- Another object of the invention is to propose a secondary lock whose tilting in the locked position is essential to authorize the mechanical coupling of the connector.
- Yet another object of the invention is to provide a secondary lock which, once in the correct locking position, locks automatically in this position, and can only be unlocked with the assistance of a tool.
- the invention relates to a connector as defined in claim 1.
- FIG. 1 the clip holder 1 of a connector according to the invention is shown with two clips 2, 3, ready to be inserted from the back, each of the two clips 2, 3 is crimped on a cable, respectively in 4 and 5.

- the clip holder 1 In his part central, the clip holder 1 carries an interfacial seal 17 sealing.
- the front face of the front part 14 of the clip holder 1 has two openings 18, 19 of general cross shape, intended to allow contact tabs to pass electric of the tab holder constituting the other element of the connector, or socket, for example.
- clips 2, 3 are in contact against the front face of the clip holder, just behind the cruciform openings 18, 19.
- the housings intended to receive the clips 2, 3 behind the openings 18, 19, are separated by a central partition 20.
- the clip holder carries a secondary lock.
- the secondary lock is symmetrical with respect to the plane longitudinal symmetry of the clip holder, and it consists by two deformable side walls 21, 22, substantially vertical in rest position, two rigid shaped wings roof with two symmetrical slopes, 23, 24, and a bar 25, substantially axial, each of the two wings 23, 24 being articulated on the one hand on a deformable side wall 21, 22 respectively, on the other hand on the bar 25.
- the bar 25 has two stable positions: one high, waiting, shown in Figure 1, the other lower, locking, shown in Figure 2.
- the bar 25 In its upper position, or the bar 25 is placed in front of the edge of the clip holder 1, in line with the interfacial joint 17, so that, by its front face which is to the right of the front face of the front part 14 of the clip holder 1, it constitutes an obstacle prohibiting coupling of the connector.

Description
L'invention concerne un connecteur à verrou secondaire intégré, par exemple un connecteur électrique à clips et languettes, dans lequel le verrou secondaire soit solidaire du porte-clips ou du porte-languettes.A secondary latch connector is provided. integrated, for example an electrical connector with clips and tabs, in which the secondary lock is integral with the clip holder or tab holder.
Dans les applications des connecteurs électriques à l'industrie et à l'automobile notamment, la technique de l'enfichage doux, c'est-à-dire à force d'enfichage faible ou très faible, est de plus en plus utilisée.In applications of electrical connectors to industry and automotive in particular, the technique of soft plug-in, i.e. with low plug-in force or very weak, is used more and more.
La force d'enfichage étant très faible, il est essentiel que les clips et languettes à accoupler soient positionnés avec exactitude et que leur position correcte puisse être contrôlée avant l'opération de connexion.As the plug-in force is very low, it is essential that the clips and tabs to be coupled are positioned with accuracy and that their correct position can be checked before the connection operation.
Les connecteurs utilisent des verrous primaires pour verrouiller en position les clips dans leur boítier en matière plastique. Ces verrous primaires sont par exemple des doigts qui s'effacent lors de l'introduction du clip dans le boítier et qui viennent constituer une butée arrière, lorsque le clip est en position correcte, pour le maintenir dans cette position correcte. Ces verrous primaires sont en général disposés à l'intérieur du boítier et ils ne sont pas visibles de l'extérieur. Si au cours de l'opération d'insertion du clip dans le boítier, le clip n'est pas amené jusqu'à sa position correcte, le verrou primaire reste en position effacée et ne joue pas son rôle, sans que cette anomalie puisse être détectée de l'extérieur. Lors d'une opération ultérieure d'accouplement du connecteur, le clip peut reculer sous la poussée de la languette et le contact peut ne pas être réalisé sans que l'opérateur en ait conscience.Connectors use primary locks to lock the clips in position in their material case plastic. These primary locks are for example fingers which are erased when the clip is inserted into the case and which constitute a rear stop, when the clip is in the correct position, to keep it in this correct position. These primary locks are usually arranged inside the case and they are not visible from the outside. If during the clip insertion operation in the case, the clip is not brought to its position correct, the primary lock remains in the cleared position and does not not play its role, without this anomaly being detected from the outside. During a subsequent operation connector coupling, the clip can move back under the tongue pushing and contact may not be made without the operator being aware of it.
Pour éviter cet inconvénient, il est prévu de disposer un verrou secondaire, c'est-à-dire une pièce supplémentaire, visible de l'extérieur ou susceptible d'empêcher l'accouplement mécanique d'un connecteur. Un tel verrou secondaire est en général une pièce extérieure, qui doit être mise en place sur le boítier, et qui prend une position correcte seulement si les organes électriques du connecteur sont en position correcte. Usuellement, ces verrous secondaires sont du type coulisseau ou tiroir, et ils sont mis en place sur le boítier au cours d'une opération d'assemblage.To avoid this drawback, it is planned to have a secondary lock, i.e. an additional part, visible from the outside or likely to prevent mechanical coupling of a connector. Such a lock secondary is usually an external part, which must be set up on the housing, and which takes a correct position only if the connector's electrical components are in the correct position. Usually, these secondary locks are of the slide or drawer type, and they are put in place on the housing during an assembly operation.
Le document WO-96-34429 décrit un connecteur électrique portant un verrou secondaire solidaire du boítier, qui a une position d'attente et une position de verrouillage, la position de verrouillage ne pouvant être atteinte que si les contacts électriques sont en position correcte, le contrôle de la position de verrouillage se faisant à la vue ou au toucher.Document WO-96-34429 describes an electrical connector carrying a secondary lock secured to the housing, which has a standby position and a locked position, the locked position cannot be reached that if the electrical contacts are in the correct position, check the locking position by sight or touch.
L'un des buts de l'invention est de proposer un verrou secondaire qui ne demande pas de pièce supplémentaire et d'opération d'assemblage, d'une part pour éviter les difficultés de cette opération d'assemblage, d'autre part pour réduire les coûts de fabrication des connecteurs.One of the aims of the invention is to propose a secondary lock which does not requires no additional parts and assembly operation, one part to avoid the difficulties of this assembly operation, on the other hand to reduce the manufacturing costs of connectors.
Un autre but de l'invention est de proposer un verrou secondaire dont le basculement en position de verrouillage soit indispensable pour autoriser l'accouplement mécanique du connecteur.Another object of the invention is to propose a secondary lock whose tilting in the locked position is essential to authorize the mechanical coupling of the connector.
Un autre but encore de l'invention est de proposer un verrou secondaire qui, une fois en position correcte de verrouillage, se verrouille automatiquement dans cette position, et ne puisse être déverrouillé qu'avec le concours d'un outil.Yet another object of the invention is to provide a secondary lock which, once in the correct locking position, locks automatically in this position, and can only be unlocked with the assistance of a tool.

Sur la figure 1, le porte-clips 1 d'un connecteur selon
l'invention est représenté avec deux clips 2, 3, prêts à être
insérés de l'arrière, chacun des deux clips 2, 3 est serti sur
un câble, respectivement en 4 et 5.In FIG. 1, the clip holder 1 of a connector according to
the invention is shown with two
Les gaines 6, 7 des câbles portent des joints d'étanchéité
sertis, 8, 9 respectivement.The
Les clips 2, 3 comportent chacun une cage, 10, 11, de forme
générale parallélépipédique.The
Entre cette cage 10, 11 et le sertissage 4, 5 sur leur câble
respectif, les clips 2, 3 présentent une zone de transition
12, 13 respectivement. Between this
Le porte-clips 1 est constitué essentiellement d'un boítier en
matière plastique, présentant une partie avant 14 destinée à
recevoir les clips 2, 3, et une partie arrière 15 destinée à
coopérer avec les joints sertis 8, 9 pour assurer l'étanchéité
du porte-clips.The clip holder 1 essentially consists of a housing made of
plastic material, having a
La partie arrière 15 porte une demi-coquille 16 s'étendant
vers l'avant et destinée à assurer une liaison mécanique avec
un porte-languettes ou une embase par exemple. Dans sa partie
centrale, le porte-clips 1 porte un joint interfacial 17
d'étanchéité.The
La face frontale de la partie avant 14 du porte-clips 1
présente deux ouvertures 18, 19 de forme générale en croix,
destinées à laisser passer les languettes de contact
électrique du porte-languettes constituant l'autre élément du
connecteur, ou de l'embase, par exemple. Lorsqu'ils sont
correctement montés, les clips 2, 3 se trouvent en appui
contre la face frontale du porte-clips, juste derrière les
ouvertures cruciformes 18, 19.The front face of the
Les logements destinés à recevoir les clips 2, 3 derrière les
ouvertures 18, 19, sont séparés par une cloison médiane 20.The housings intended to receive the
Au dessus des logements destinés à recevoir les clips 2, 3, le
porte-clips porte un verrou secondaire.Above the housings intended to receive
Le verrou secondaire est symétrique par rapport au plan
longitudinal de symétrie du porte-clips, et il est constitué
par deux parois latérales déformables 21, 22, sensiblement
verticales en position de repos, deux ailes rigides en forme
de toit à deux pentes symétriques, 23, 24, et une barre 25,
sensiblement axiale, chacune des deux ailes 23, 24 étant
articulée d'une part sur une paroi latérale déformable 21, 22
respectivement, d'autre part sur la barre 25.The secondary lock is symmetrical with respect to the plane
longitudinal symmetry of the clip holder, and it consists
by two
La barre 25 a deux positions stables : l'une haute, d'attente,
représentée sur la figure 1, l'autre basse, de verrouillage,
représentée sur la figure 2. Dans sa position haute, ou
d'attente, la barre 25 est placée devant le bord du porte-clips
1, au droit du joint interfacial 17, de sorte que, par
sa face frontale qui est au droit de la face frontale de la
partie avant 14 du porte-clips 1, elle constitue un obstacle
interdisant l'accouplement du connecteur. Dans sa position
basse, ou de verrouillage, la barre 25 est appliquée sur la
cloison médiane 20 ; elle est entièrement logée à l'intérieur
du volume intérieur du porte-clips 1 et autorise
l'accouplement du connecteur.The
Le passage de la position haute à la position basse s'effectue
par flexion vers l'extérieur des parois latérales déformables
21, 22 sous l'action d'une pression exercée sur la barre 25 et
transmise par les ailes rigides 23, 24. Au cours du mouvement
de descente de la barre 25, l'inclinaison des ailes 23, 24 sur
le plan horizontal a tendance à diminuer jusqu'à s'annuler au
moment où les parois latérales sont déformées au maximum vers
l'extérieur, puis cette inclinaison s'inverse et augmente
jusqu'à la position la plus basse de la barre 25.The transition from the high position to the low position takes place
by outward bending of the
Le passage de la position stable d'attente à la position
stable de verrouillage s'effectue avec effet avalant, ou de
déclic, en raison de l'élasticité des parois latérales 21, 22.The transition from the stable waiting position to the position
stable locking is effected with swallowing effect, or
click, due to the elasticity of the
Sur la figure 3 la barre 25 est visible en appui sur la
cloison médiane 20. A sa partie arrière, au droit du joint
interfacial 17, la barre 25 porte un pion 26 destiné à être
inséré en arrière des zones de transition 12, 13 des clips 2,
3.In FIG. 3, the
La figure 5 montre l'emprise de ce pion 26 qui présente à
l'arrière un talon 27 coulissant dans une rainure verticale 28
de la partie arrière 15 du porte-clips 1. La rainure 28 assure
le guidage du pion 26 au cours de son mouvement vertical
imposé par la barre 25. Le fond de la rainure joue le rôle de
butée arrière pour le pion 26 et la barre 25 de façon à éviter
une dégradation de la fonction de verrouillage en cas d'effort
vers l'arrière subi par la barre 25 avant que le verrou
secondaire ne soit fermé.Figure 5 shows the grip of this
Le pion 26 présente vers l'avant deux chanfreins latéraux 29,
30 destinés à se glisser derrière les zones de transition 12,
13 des clips 2, 3, d'une part pour autoriser la descente du
pion 26 mettant en évidence le positionnement correct des
clips dans le boítier, d'autre part pour contribuer à
renforcer la fonction de maintien des verrous primaires sur
les clips.The
Le pion 26 présente vers l'avant un évidement 31 qui entoure
un linguet 32 de verrouillage. Ce linguet 32 est muni à son
extrémité inférieure d'un crochet 33 susceptible de
s'accrocher sous un épaulement 34 de la cloison médiane 20
réalisant ainsi la fonction de verrouillage de sécurité de
l'ensemble 23-24-25-26 en position basse de verrouillage
secondaire.The
Au cours du mouvement de descente de la barre 25 et du pion
26, le linguet 32 s'efface vers l'arrière car son extrémité
inférieure est chanfreinée du côté du crochet 33. Lorsque le
pion 26 est arrivé en position basse correcte, le crochet 33
vient s'encliqueter sous l'épaulement 34.During the downward movement of the
La figure 4 permet de constater que si un clip n'est pas en
position correcte dans le boítier, c'est-à-dire s'il n'est pas
en position avancée contre la paroi frontale du porte-clips,
la zone de transition, 12 par exemple, et le cas échéant la
cage 10 du clip empêchent la descente du pion 26 et la
réalisation de la fonction de verrouillage secondaire. Dans ce
cas, d'une part la barre 25 ne peut pas descendre au bout de
sa course et elle empêche l'accouplement du connecteur,
d'autre part le crochet 33 du linguet 32 ne peut pas
s'encliqueter sous l'épaulement 34 et la fonction de
verrouillage de sécurité ne peut être assurée.Figure 4 shows that if a clip is not in
correct position in the housing, i.e. if it is not
in the advanced position against the front wall of the clip holder,
the transition zone, 12 for example, and where appropriate the
La figure 6 montre en vue simplifiée que le pion 26 solidaire
de la barre 25 est, lors du moulage par injection du boítier
du porte-clips, solidaire de cloisons latérales 35, 36, par
l'intermédiaire de liens 37, 38 très fins. Ces liens ont pour
rôle d'abord de faciliter l'injection du pion, ensuite
d'assurer le centrage du pion avant manoeuvre du verrou
