Definitions
- connection modules with removable contacts and in particular (although not exclusively) those insertable side by side in a plate module holder to constitute a connection block.
- connection block can easily be designed to incorporate modules giving the contacts a step of variable distribution from one module to another. he is also possible to install a number of modules lower than the number maximum allowable.
- each module is formed passages intended to receive the contacts and each provided with retaining pawls.
- connection module plug-in electric aims to provide a connection module plug-in electric responding better than those previously known to the requirements of the practice, in particular in that that it allows an energetic locking of the contacts as well that an easy installation and removal of the contacts, while having a relatively simple constitution.
- the invention notably proposes a module according to claim 1.
- the module can have at least some of the defined characteristics by claims 2 to 9.
- the module can have characteristics among those defined in claims 10 to 17 which are those other embodiments.
- the invention also provides a block of connection comprising modules of the above type defined and a receiving stage, according to claim 18.
- connection block 10 shown in Figures 1 to 6 is intended to receive female electrical contacts 12 and to plug into an additional connection block fitted male contacts, not shown.
- Such a block 10 is in particular usable for equipping motor vehicles.
- the complementary block having male contacts can have a similar constitution.
- Block 10 includes a plate 14 intended to receive modules 16.
- its central part is shaped frame, having side members 18 delimiting a corridor central. Side ears 19 of the plate allow to fix it.
- Each module 16 consists of a housing 20 and a plate 22 for retaining the module contacts. It is provided to be locked on the side rails in one position adjacent to another module or to other modules. pressing of the module in the stage window when it locking is defined by stop means provided on the housing and intended to come into contact with the side members.
- the elastic locking means fix the module to the side members. They understand, on each case, two external retention arms 24, one piece with the rest of the case, intended to frame the longitudinal members, and elastic tabs 26 for internal retention, also in one piece with the rest of the case.
- the external retention arms 26 are each terminated by a catch notch 28 intended to snap onto a external shoulder 30 of the respective side members. This shoulder 30 extends over the entire length of the spar.
- the arm 24 could be long enough for its notch hooks snaps onto the edge of the side member, but this provision would constitute a projection which could limit the reconciliation of the block and an additional block during plugging.
- the presence of external shoulders 30 allows arms 24 which do not extend beyond the side members. Stop means of each box are formed by the connection of retaining arms external to the main part of the housing.
- the internal elastic tabs 26 are designed to snap onto an internal shoulder respective side members.
- passages 34 of electrical contacts which are female contacts in the particular case shown in Figure 5.
- Each plate 22 is designed to receive contacts and hold them when it is completely engaged in the respective housing.
- the plate is designed to resiliently lock on the plate, in a position determined in relation to the respective housing.
- the plate 22 ( Figures 2 and 4) has a bottom pierced with passages for contacts, and lateral hooking arms 38. The bottom is extended by elastic catches 36 contact retention. The spacing of the latches of a same passage is prohibited by the wall of the respective passage 34 of the housing when the plate is fully inserted in the case. This method of retaining contacts will not be further described because it is well known. We can in particular refer, in this regard, to document EP-A-0 576 345.
- the plate hooking means intended to immobilize it on the turntable, include, in the embodiment of FIGS. 1 to 6, the lateral arms 38, provided for this purpose each of a terminal hooking notch. These notches can be provided to snap onto the same shoulder 32 than the one used for the legs elastic bands 26. As shown in particular in FIG. 2, two 26 legs can be provided on each side of each case, so as to leave a free passage for the arm 38 which fits between them.
- the plate 22 can be retained in a pre-locking position leaving the latches 36 free, so that the contacts can then be set up and removed.
- the plate and the housing carry provisional retaining means of the plate in a retracted position.
- these means are constituted by provisional retaining notches 40 constituting the projections external of each plate 22, intended to engage each in a window 42 of elongated shape with a partition extending laterally one of the sides of the case.
- a cross member 44 (figure 4) fixing the provisional retaining position of the plate.
- the plate, the case and the plates are generally made of a single piece of molded plastic, possibly reinforced by charges.
- the shape of these pieces is simple enough that the molds of manufacturing are feasible at a moderate price.
- each plate is locked in the position where it prohibits placing or removing contacts only when its attachment means are fixed to the plate 14.
- the plate 22 is locks on the housing 20, so that each module containing contacts can be handled without risk of the contacts do not escape.
- the plate 22 is then devoid of lateral arms 38 hooking on the plate.
- the housing 20 is provided with elastic pawls 46 which, when the plate is fully inserted in the housing, come to hang on the back edge of the plate, as shown in the left side of figure 9.
- These pawls can be guided, during their introduction, by arranged corridors in lateral bulges 48 of the plates.
- the corridor wall has a inclined zone 50 which gradually bends the pawl at as it is introduced.
- the corridor wall has a shoulder 52 whose location is such that when the pawl 46 is pressed against the shoulder 52, without being prestressed, the plate 22 and the housing 20 are in the pre-locking position allowing inserting and removing contacts.
- the exact pre-lock position can be fixed by comparable means, in their structure or their function, to the notch 40 and to the cross member 44 of FIG. 4.
- a block can also be provided to receive male contacts. Its constitution then differs from that which has been described by the arrangement of the guide members provided in the ears of the turntable.
- the module still consists of a housing 120 and a contact retaining plate 122 112 (FIGS. 13A to 13D, 14 and 15).
- the housing 120 is intended to be locked on the longitudinal members of a plate 114 in a position adjacent to a other module.
- the elastic locking means of the housing on the side members include, on each housing, two external retention arms 124, in one piece with the rest of the case, intended to frame the side members of the platinum 114.
- These external retention arms 124 terminate each by a hooking notch 128 intended to snap on an external shoulder 130 of a respective spar.
- These means also include internal arms 126 separated from the main part of the case, intended to receive the contacts 112.
- housing 120 In the housing 120 are formed parallel passages 134 for receiving the female electrical contacts 112.
- the plate 122 is designed to receive the contacts electrically and retain them energetically.
- the plate 122 has a bottom pierced with passages for the contacts and constituting a shoulder of support of a first flange 150 of the respective contact.
- the bottom is extended by elastic latches 136 of retained contacts.
- Each latch 136 has, from of its root, an elastic part, then a portion angled 137 intended to rest on a second flange 152 of a contact ( Figures 13c and 13D).
- the distance between the shoulder and the angled portion 137 is very slightly greater than the distance between the facing faces of flanges 150 and 152.
- the bent part has a sufficient height for it to rest on the housing 120 when the plate is locked on the housing.
- Each latch 136 is extended by a finger 154 to curved end.
- the finger When the finger is in the free state ( Figure 13A), it has a shape such that it abuts against a terminal boss 156 of the housing if the plate is pressed. But the curvature of the end is such that the boss flexes the latch outward under the action of the driving force and allows the pawl to come into the position shown in Figure 13D.
- the plate locking means include lateral elastic arms 138 in one piece with the retaining plate, extending from the rear of the plate, framing the retaining plate and extending beyond latches down. These side arms are provided with lugs terminals intended to engage in holes 158 of the arms internal of the case. The arms can have a part swollen and striated 160 to better grasp them. Between the body of the housing and each arm is provided an interval sufficient to allow the pins to be released by bending arms. By bringing them together by hand, we can engage the plate first to the intermediate position shown in figure 12, then to the locking position where the pins engage elastically in the holes 158.
- the contacts can be set up whatever the position of the plate relative to the housing, even when the plate is locked on the housing. However, the contacts cannot be removed from the plate without intervention manually on the latches only when the plate is in the position shown in Figure 13C.
- the plate and the housing carry means for temporary withholding. In the case illustrated in Figures 11 and 12, these means are constituted by notches 140 constituting external projections of the housing and each engaging in a window 142 of elongated shape with a partition extending laterally one of the sides of the plate. The position of the plate can be freely adjusted between positions shown in Figures 11 and 12.
- Figures 13A and 13B show that the contacts 112 can be inserted when the plate is in position retracted.
- Figure 14 shows that the contacts can also be inserted, pushing back the latches 136, while the plate 122 is locked on the housing 120.
- contacts can only be removed when the plate is in the position shown in the figure 13C, where its latches are pushed back by the bosses 156. They can no longer be locked when the plate is locked on the housing (Figure 3D).
- the housing 120 has lateral stops 162 delimiting cavities in which the fingertips 154 when the plate is locked on the housing. The stops prevent bending of the fingers and latches and therefore the introduction of the contacts.
- FIG. 16 shows an alternative embodiment of the housing 120 in which an intermediate position of the plate, where insertion and extraction are allowed, is fixed by notches 164 of the internal arms 126. If one push the plate in without bringing the arms 138 together, the plate advance to the position of figure 12 where it is retained forwards by the support of the lugs, towards the rear by the notches 140. To fully insert the plate, it must first clear the notches by bringing the arms together side elastic 138, then push the plate until that the pins are opposite the holes 158.

Il est également possible de monter un nombre de modules inférieur au nombre maximum admissible.Such a connection block can easily be designed to incorporate modules giving the contacts a step of variable distribution from one module to another. he is also possible to install a number of modules lower than the number maximum allowable.
Un bloc de connexion électrique de ce genre est décrit dans le document EP-A-0 500 425. Dans chaque module sont ménagés des passages destinés à recevoir les contacts et munis chacun de cliquets de retenue.Such an electrical connection block is described in document EP-A-0 500 425. In each module are formed passages intended to receive the contacts and each provided with retaining pawls.
L'invention vise à fournir un module de connexion électrique enfichable répondant mieux que ceux antérieurement connus aux exigences de la pratique, notamment en ce qu'il permet un verrouillage énergique des contacts ainsi qu'une mise en place et un enlèvement faciles des contacts, tout en ayant une constitution relativement simple.The invention aims to provide a connection module plug-in electric responding better than those previously known to the requirements of the practice, in particular in that that it allows an energetic locking of the contacts as well that an easy installation and removal of the contacts, while having a relatively simple constitution.

Pour faciliter la mise en place et l'enlèvement des
contacts et/ou un démontage du module, sans outillage, tout
en conservant une constitution relativement simple, le
module peut présenter des caractéristiques parmi celles
définies dans les revendications 10 à 17, qui sont celles
d'autres modes de réalisation.To facilitate the placement and removal of

Le bloc de connexion 10 montré en figures 1 à 6 est
destiné à recevoir des contacts électriques femelles 12 et
à s'enficher dans un bloc de connexion complémentaire équipé
de contacts mâles, non représentés. Un tel bloc 10 est
notamment utilisable pour équiper les véhicules automobiles.
Le bloc complémentaire ayant des contacts mâles peut avoir
une constitution similaire.The
Le bloc 10 comprend une platine 14 destinée à recevoir
des modules 16. Pour cela, sa partie centrale est en forme
de cadre, ayant des longerons 18 délimitant un couloir
central. Des oreilles latérales 19 de la platine permettent
de la fixer.
Chaque module 16 est constitué d'un boítier 20 et d'une
plaque 22 de retenue des contacts du module. Il est prévu
pour être verrouillé sur les longerons dans une position
adjacente à un autre module ou à d'autres modules. L'enfoncement
du module dans la fenêtre de la platine lors de son
verrouillage est défini par des moyens de butée ménagés sur
le boítier et destinés à venir en contact avec les longerons. Each
Dans le mode particulier de réalisation montré en
figures 1 à 6, les moyens de verrouillage élastique fixent
le module aux longerons. Ils comprennent, sur chaque
boitier, deux bras de rétention externes 24, d'une seule
pièce avec le reste du boítier, destinés à encadrer les
longerons, et des pattes élastiques 26 de rétention internes,
également d'une seule pièce avec le reste du boítier.
Les bras de rétention externes 26 sont terminés chacun par
un cran d'accrochage 28 destiné à s'encliqueter sur un
épaulement externe 30 des longerons respectifs. Cet épaulement
30 s'étend sur toute la longueur du longeron. Le bras
24 pourrait être suffisamment long pour que son cran
d'accrochage s'encliquète sur la tranche du longeron, mais
cette disposition constituerait une saillie pouvant limiter
le rapprochement du bloc et d'un bloc complémentaire lors de
l'enfichage. Comme le montre notamment la figure 5, la
présence des épaulements externes 30 permet d'avoir des bras
24 qui ne dépassent pas les longerons. Les moyens de butée
de chaque boítier sont constitués par le raccordement des
bras de retenue externes à la partie principale du boítier.In the particular embodiment shown in
Figures 1 to 6, the elastic locking means fix
the module to the side members. They understand, on each
case, two
De façon similaire, les pattes élastiques internes 26
sont prévues pour s'encliqueter sur un épaulement interne
des longerons respectifs.Similarly, the internal
Dans les boítiers sont ménagés des passages 34 de
contacts électriques, qui sont des contacts femelles dans le
cas particulier montré en figure 5.In the housings are provided
Chaque plaque 22 est prévue pour recevoir des contacts
électriques et les retenir lorsqu'elle est complètement
engagée dans le boítier respectif. Dans le mode de réalisation
montré en figures 1 à 6, la plaque est prévue pour se
verrouiller élastiquement sur la platine, dans une position
déterminée par rapport au boítier respectif. Pour cela, la
plaque 22 (figures 2 et 4) présente un fond percé de
passages pour les contacts, et des bras latéraux d'accrochage
38. Le fond est prolongé par des linguets élastiques
36 de retenue des contacts. L'écartement des linguets d'un
même passage est interdit par la paroi du passage respectif
34 du boítier lorsque la plaque est complètement enfoncée
dans le boítier. Ce mode de retenue des contacts ne sera pas
davantage décrit, car il est bien connu. On pourra notamment
se reporter, à ce sujet, au document EP-A-0 576 345.Each
Les moyens d'accrochage de la plaque, destinés à l'immobiliser
sur la platine, comprennent, dans le mode de
réalisation des figures 1 à 6, les bras latéraux 38, munis
à cet effet chacun d'un cran d'accrochage terminal. Ces
crans peuvent être prévus pour s'encliqueter sur le même
épaulement 32 que celui qui est utilisé pour les pattes
élastiques 26. Comme le montre notamment la figure 2, deux
pattes 26 peuvent être prévues de chaque côté de chaque
boítier, de façon à laisser libre un passage pour le bras 38
qui vient s'insérer entre elles.The plate hooking means, intended to immobilize it
on the turntable, include, in the
embodiment of FIGS. 1 to 6, the
Pour faciliter la mise en place et l'enlèvement des
contacts, il est avantageux que la plaque 22 puisse être
retenue dans une position de pré-verrouillage laissant les
linguets 36 libres, de façon que les contacts puissent alors
être mis en place et enlevés. Pour cela, la plaque et le
boítier portent des moyens de retenue provisoire de la
plaque dans une position reculée. Dans le mode de réalisation
des figures 1 à 6, ces moyens sont constitués par des
crans de retenue provisoire 40 constituant les saillies
externes de chaque plaque 22, destinés à s'engager chacun
dans une fenêtre 42 de forme allongée d'une cloison prolongeant
latéralement l'un des flancs du boítier. Dans l'une
des fenêtres peut être réservée une traverse 44 (figure 4)
fixant la position de retenue provisoire de la plaque.To facilitate the placement and removal of
contacts, it is advantageous that the
La platine, le boítier et les plaques sont généralement constitués d'une seule pièce en matière plastique moulée, éventuellement renforcée par des charges. La forme de ces pièces est suffisamment simple pour que les moules de fabrication soient réalisables à un prix modéré.The plate, the case and the plates are generally made of a single piece of molded plastic, possibly reinforced by charges. The shape of these pieces is simple enough that the molds of manufacturing are feasible at a moderate price.
Dans le mode de réalisation des figures 1 à 6, chaque
plaque n'est verrouillée dans la position où elle interdit
la mise en place ou l'enlèvement des contacts que lorsque
ses moyens d'accrochage sont fixés sur la platine 14.In the embodiment of Figures 1 to 6, each
plate is locked in the position where it prohibits
placing or removing contacts only when
its attachment means are fixed to the
Dans certains cas, il est préférable que la plaque 22 se
verrouille sur le boítier 20, de façon que chaque module
contenant des contacts puisse être manipulé sans risque que
les contacts ne s'échappent. On peut dans ce cas adopter
l'un des modes de réalisation montrés sur les figures 7 à
10, où les organes correspondant à ceux déjà représentés sur
les figures 1 à 6 sont désignés par le même numéro de
référence. La plaque 22 est alors démunie de bras latéraux
38 d'accrochage sur la platine. En revanche, le boítier 20
est muni de cliquets élastiques 46 qui, lorsque la plaque
est complètement enfoncée dans le boítier, viennent s'accrocher
sur la tranche arrière de la plaque, comme le montre la
partie gauche de la figure 9. Ces cliquets peuvent être
guidés, lors de leur introduction, par des couloirs ménagés
dans des renflements latéraux 48 des plaques. Dans le cas
illustré sur la figure 9, la paroi des couloirs présente une
zone inclinée 50 qui fléchit progressivement le cliquet au
fur et à mesure de son introduction.In some cases, it is preferable that the
Le cran terminal du cliquet 46 ainsi mis en précontrainte
progressive vient s'encliqueter sur la tranche
arrière de la plaque lorsque cette dernière arrive dans sa
position d'engagement complet.The final catch of the
Dans la variante de réalisation montrée en figure 10, la
paroi du couloir présente un épaulement 52 dont l'emplacement
est tel que lorsque le cliquet 46 est en appui contre
l'épaulement 52, sans être en précontrainte, la plaque 22 et
le boítier 20 sont dans la position de préverrouillage autorisant
l'insertion et l'enlèvement des contacts. Dans ce cas
encore, la position exacte de préverrouillage peut être fixée
par des moyens comparables, dans leur structure ou leur
fonction, au cran 40 et à la traverse 44 de la figure 4.In the variant embodiment shown in FIG. 10, the
corridor wall has a
Un bloc peut également être prévu pour recevoir des contacts mâles. Sa constitution diffère alors de celle qui a été décrite par la disposition des organes de guidage prévus dans les oreilles de la platine.A block can also be provided to receive male contacts. Its constitution then differs from that which has been described by the arrangement of the guide members provided in the ears of the turntable.
Dans tous les modes de réalisation des figures 11 à 16,
le module est encore constitué d'un boítier 120 et d'une
plaque 122 de retenue de contacts 112 (figures 13A à 13D, 14
et 15).In all the embodiments of FIGS. 11 to 16,
the module still consists of a
Le boítier 120 est prévu pour être verrouillé sur les
longerons d'une platine 114 dans une position adjacente à un
autre module.The
Dans le mode particulier de réalisation montré en
figures 11 et 12, les moyens de verrouillage élastiques du
boítier sur les longerons comprennent, sur chaque boítier,
deux bras de rétention externes 124, d'une seule pièce avec
le reste du boítier, destinés à encadrer les longerons de la
platine 114. Ces bras de rétention externes 124 se terminent
chacun par un cran d'accrochage 128 destiné à s'encliqueter
sur un épaulement externe 130 d'un longeron respectif. Ces
moyens comportent également des bras internes 126 écartés de
la partie principale du boítier, destinée à recevoir les
contacts 112.In the particular embodiment shown in
Figures 11 and 12, the elastic locking means of the
housing on the side members include, on each housing,
two

électriques et les retenir de façon énergique.The
Pour cela, la plaque 122 présente un fond percé de
passages pour les contacts et constituant un épaulement
d'appui d'une première collerette 150 du contact respectif.
Le fond est prolongé par des linguets élastiques 136 de
retenue des contacts. Chaque linguet 136 présente, à partir
de son emplanture, une partie élastique, puis une portion
coudée 137 destinée à s'appuyer sur une seconde collerette
152 d'un contact (figures 13c et 13D). La distance entre
l'épaulement et la portion coudée 137 est très légèrement
supérieure à la distance entre les faces en regard des
collerettes 150 et 152. La partie coudée présente une
hauteur suffisante pour qu'elle s'appuie sur le boítier 120
lorsque la plaque est verrouillée sur le boítier.For this, the
Chaque linguet 136 se prolonge par un doigt 154 à
extrémité courbe. Lorsque le doigt est à l'état libre
(figure 13A), il a une forme telle qu'il vient buter contre
un bossage terminal 156 du boítier si on enfonce la plaque.
Mais la courbure de l'extrémité est telle que le bossage
fléchit le linguet vers l'extérieur sous l'action de la
force d'enfoncement et permet au linguet de venir dans la
position montrée en figure 13D.Each
Les moyens de verrouillage de la plaque comprennent des
bras élastiques latéraux 138 d'une seule pièce avec la
plaque de retenue, s'étendant à partir de l'arrière de la
plaque, encadrant la plaque de retenue et dépassant les
linguets vers le bas. Ces bras latéraux sont munis d'ergots
terminaux destinés à s'engager dans des trous 158 des bras
internes du boítier. Les bras peuvent présenter une partie
renflée et striée 160 permettant de mieux les saisir. Entre
le corps du boítier et chaque bras est ménagé un intervalle
suffisant pour permettre de dégager les ergots en fléchissant
les bras. En les rapprochant à la main, on peut engager
la plaque d'abord jusqu'à la position intermédiaire montrée
en figure 12, puis jusqu'à la position de verrouillage où
les ergots s'engagent élastiquement dans les trous 158.The plate locking means include
lateral
Dans le mode de réalisation montré en figures 11 à 14,
les contacts peuvent être mis en place quelle que soit la
position de la plaque par rapport au boítier, même lorsque
la plaque est verrouillée sur le boítier. En revanche, les
contacts ne peuvent être retirés de la plaque sans intervention
manuelle sur les linguets que lorsque la plaque est
dans la position montrée en figure 13C. Pour éviter de tirer
par inadvertance le tiroir au-delà de cette position de pré-verrouillage,
la plaque et le boítier portent des moyens de
retenue provisoire. Dans le cas illustré en figures 11 et
12, ces moyens sont constitués par des crans 140 constituant
des saillies externes du boítier et s'engageant chacun dans
une fenêtre 142 de forme allongée d'une cloison prolongeant
latéralement un des flancs de la plaque. La position de la
plaque peut être ajustée librement entre les positions
montrées en figures 11 et 12.In the embodiment shown in FIGS. 11 to 14,
the contacts can be set up whatever the
position of the plate relative to the housing, even when
the plate is locked on the housing. However, the
contacts cannot be removed from the plate without intervention
manually on the latches only when the plate is
in the position shown in Figure 13C. To avoid shooting
inadvertently the drawer beyond this pre-locking position,
the plate and the housing carry means for
temporary withholding. In the case illustrated in Figures 11 and
12, these means are constituted by
Les figures 13A et 13B montrent que les contacts 112
peuvent être insérés lorsque la plaque est en position
rétractée. La figure 14 montre que les contacts peuvent
également être insérés, en repoussant les linguets 136,
alors que la plaque 122 est verrouillée sur le boítier 120.
En revanche, les contacts ne peuvent être retirés que
lorsque la plaque est dans la position montrée en figure
13C, où ses linguets sont repoussés par les bossages 156.
Ils ne peuvent plus l'être lorsque la plaque est verrouillée
sur le boítier (figure 3D).Figures 13A and 13B show that the
Dans la variante de réalisation montrée en figure 15 au
contraire, le boítier 120 comporte des butées latérales 162
délimitant des cavités dans lesquelles s'engagent les
extrémités des doigts 154 lorsque la plaque est verrouillée
sur le boítier. Les butées interdisent la flexion des doigts
et des linguets et donc l'introduction des contacts.In the alternative embodiment shown in FIG. 15 at
on the contrary, the
La figure 16 montre une variante de réalisation du
boítier 120 dans laquelle une position intermédiaire de la
plaque, où l'insertion et l'extraction sont autorisées, est
fixée par des encoches 164 des bras internes 126. Si on
enfonce la plaque sans rapprocher les bras 138, la plaque
avance jusqu'à la position de la figure 12 où elle est
retenue vers l'avant par l'appui des ergots, vers l'arrière
par les crans 140. Pour enfoncer complètement la plaque, il
faut d'abord dégager les crans en rapprochant les bras
élastiques latéraux 138, puis pousser la plaque jusqu'à ce
que les ergots soient en face des trous 158.FIG. 16 shows an alternative embodiment of the
