Description
L'invention concerne un connecteur femelle à sertir apte à recevoir une languette de connexion mâle, en vue d'établir une connexion électrique.The invention relates to a female crimp connector suitable to receive a male connection tab, in view to establish an electrical connection.
Des connecteurs femelles de type connu sont par exemple des cosses femelles vendues sous la dénomination "drapeau de sécurité à enfichage doux et déverrouillage manuel" par la déposante. Ces cosses femelles comportent une cage d'enfichage apte à recevoir une languette mâle et un bloc de raccordement apte à sertir à coeur un conducteur électrique et à pincer l'isolant de protection de ce conducteur électrique.Known type female connectors are for example female pods sold under the name "flag safety device with soft plug and manual unlocking " by the applicant. These female pods have a cage fitting capable of receiving a male tab and a block connection capable of crimping a conductor to the core electrical and pinch the protective insulation from it electrical conductor.
Ces dispositifs connus combinant une zone de sertissage, une zone de transition et une zone d'enfichage donnent généralement satisfaction. Cependant, du fait que ces connecteurs sont réalisés par découpe et pliage de bandes métalliques, le coût de la matière de ces connecteurs est proportionnel à la dimension de leur surface découpée à plat avant pliage. Egalement, dans les applications privilégiant un encombrement minimal, la dimension de ces connecteurs peut s'avérer pénalisante.These known devices combining a crimping zone, a transition zone and a plug-in zone give generally satisfied. However, because these connectors are made by cutting and folding strips the cost of the material of these connectors is proportional to the size of their cut surface at flat before folding. Also, in applications favoring minimal bulk, the size of these connectors can be detrimental.
Le document US-A-3 771 111 décrit un connecteur femelle de type "drapeau", comportant une zone de sertissage, une zone de transition et d'une zone d'enfichage. Dans la zone de sertissage, l'une des ailes de sertissage du conducteur est prélevée sur la zone de transition. Par ailleurs, la pince de maintien de l'isolant du conducteur est asymétrique car du côté de la zone de transition, seule une petite bande de matière peut être prélevée. La pince de maintien de l'isolant du conducteur comporte donc une aile courte du côté de la zone de transition et une aile longue de l'autre côté. Cette dissymétrie entraíne une difficulté de réalisation de l'appareillage automatique de sertissage.Document US-A-3,771,111 describes a female connector "flag" type, comprising a crimping zone, a transition zone and a plug-in zone. In the crimping area, one of the crimping wings of the conductor is taken from the transition zone. Through elsewhere, the conductor insulator retaining clip is asymmetrical because on the side of the transition zone, only a small strip of material can be removed. The conductor insulation holding clip has so a short wing on the side of the transition zone and a long wing on the other side. This asymmetry leads to a difficulty in achieving the apparatus automatic crimping.

La zone de transition est pliée à ses deux extrémités : pour réduire la dimension maximale du connecteur, pour permettre l'insertion d'une languette mâle de contact pour chacune des deux extrémités de la zone d'enfichage et pour permettre le sertissage..Document US A 3,430,191 describes a female connector of "flag" type, comprising a crimping area, a transition zone and a plug-in zone. The area of transition is folded at both ends: to reduce the maximum dimension of the connector, to allow inserting a male contact tab for each from both ends of the plug-in area and for allow crimping ..
Par rapport au plan de la feuille métallique découpée pour constituer le connecteur, la zone d'enfichage se trouve d'un côté, et la zone de sertissage se trouve de l'autre côté.In relation to the plane of the cut metal sheet to form the connector, the plug-in area is on one side, and the crimp area is on the other side.

En référence aux figures 1 et 2, les chiffres de référence identiques désignent des éléments identiques ou fonctionnellement équivalents entre eux.With reference to Figures 1 and 2, the reference numbers identical denote identical elements or functionally equivalent to each other.
Le connecteur femelle comporte un bloc de raccordement 1
s'étendant transversalement à la cage d'enfichage 2 et
relié à celle-ci par une zone de transition 3.The female connector includes a
Selon l'invention, la zone de transition 3 comporte une
onde 4 avec une découpe centrale 15 correspondant au moins
partiellement à une aile 6 du bloc de raccordement.According to the invention, the
Avantageusement, les dimensions de la découpe centrale 15
correspondent au passage d'une pince à sertir, de manière à
centrer les mâchoires de la pince à sertir lors du
sertissage.Advantageously, the dimensions of the
Du côté de la cage d'enfichage 2 apte à recevoir une
languette mâle non représentée, l'onde 4 présente en
section un bord sensiblement vertical 5.On the side of the plug-in
Du côté du bloc de raccordement 1, l'onde 4 présente en
section une courbe 6a se rattachant tangentiellement au
fond 7 du canal de sertissage du bloc de raccordement 1.On the side of the
La courbe 6a est déterminée de manière à ne pas interférer
avec le passage d'un conducteur à sertir dans le bloc de
raccordement 1 : la courbure de la courbe 6a est choisie de
manière à ne pas interférer avec le volume limité par le
fond 7 du canal de sertissage et les ailettes de sertissage
de conducteur 6 ou les ailettes de maintien de l'isolant 8.
La cage d'enfichage 2 représentée est du type à enfichage
doux et comporte une rainure centrale et un organe de
verrouillage de languettes disposés sur le plancher 9 de la
cage d'enfichage; l'invention s'étend à toute variante de
réalisation dans laquelle la cage d'enfichage 2 serait d'un
type différent, et notamment à celle décrite aux figures 5
et 6, qui comporte quatre lames de contact.The plug-in
L'onde 4 de la zone de transition 3 est reliée à la cage
d'enfichage par deux zones de raccordement 10 et 11 reliées
non seulement au plancher 9 de la cage d'enfichage, mais au
moins partiellement à une paroi latérale 12 par
l'intermédiaire de deux bords relevés 13 de raidissement.
Ainsi, malgré la faible quantité de matière utilisée, la
zone de transition 3 est reliée de manière rigide et stable
au plancher de la cage d'enfichage et au moins à une des
parois latérales 12 : cette disposition écarte tout risque
de fracture ou de fissure entre la cage d'enfichage 2 et la
zone de transition 3.The
Egalement, du côté du bloc de raccordement 1, le
raccordement continu de la courbe 6a au fond 7 du canal
écarte tout risque de fracture ou de fissure en dépit de
cycles d'échauffement ou de vibration répétés.Also, on the side of the
En référence aux figures 3 et 4, les chiffres de référence identiques désignent des éléments identiques ou fonctionnellement équivalents à ceux des figures 1 et 2With reference to Figures 3 and 4, the reference figures identical denote identical elements or functionally equivalent to those of Figures 1 and 2
La distance D séparant l'entrée d'enfichage de la cage
d'enfichage 2 de l'axe du canal de sertissage est, en
raison de la disposition d'une onde dans la zone de
transition entre le bloc de raccordement et la cage
d'enfichage, très inférieure à la distance correspondante
des connecteurs de l'art antérieur. Cet avantage procuré
par l'invention permet d'envisager l'utilisation des
connecteurs selon l'invention dans de nouvelles
applications d'électronique domestique, qui n'étaient pas
ouvertes aux connecteurs de l'art antérieur présentant un
encombrement supérieur.The distance D between the plug-in entry and the
Ainsi, le connecteur selon l'invention pourra être utilisé non seulement dans des applications de fabrication d'appareils électroménagers, d'appareils de cuisson, de fours à micro-ondes ou de commutateurs de puissance divers, en fabrication automobile, mais également dans des applications de micro-électronique et d'appareils d'enregistrement et de reproduction du son.Thus, the connector according to the invention can be used not only in manufacturing applications household appliances, cooking appliances, microwave ovens or various power switches, in automobile manufacturing, but also in microelectronics and device applications sound recording and reproduction.
La rigidité et la résistance du connecteur selon l'invention sont encore améliorées, dans le cas où aucun effort de flexion parasite n'est pratiqué sur celui-ci lors de l'enfichage d'une languette mâle ou lors du sertissage à coeur d'un conducteur.The stiffness and strength of the connector according to the invention are further improved, in the event that none parasitic bending force is not applied to it during when inserting a male tab or when crimping heart of a driver.
A cet effet, selon la variante préférée représentée, on
prévoit que l'axe de sertissage 14 correspondant après
sertissage à l'axe du conducteur serti soit situé
sensiblement dans le plan médian 16 de la cage d'enfichage
2. Cette disposition avantageuse permet en outre, malgré la
présence de l'onde 4 de la zone de transition 3 d'obtenir
un connecteur femelle sensiblement coplanaire et apte à
être livré et manutentionné de la même manière que les
connecteurs de l'art antérieur. Cette compatibilité de
conditionnement, d'emballage et de manutention conserve
ainsi les avantages de l'art antérieur et facilite
l'application et le montage automatique des connecteurs
selon l'invention.For this purpose, according to the preferred variant shown, we
provides that the corresponding crimping

identiques à ceux des figures 1 à 4 désignent des éléments
identiques ou techniquement équivalents. Les principales
différences entre le mode de réalisation des figures 1 et 2
et celui des figures 5 et 6 résident dans la structure de
la cage d'enfichage 2. Sur les figures 5 et 6, cette cage 2
présente quatre lames, respectivement 17, 18 sur la figure
5 et 19, 20 sur la figure 6. Lorsque la languette mâle est
introduite dans la cage d'enfichage, elle écarte les quatre
lames 17 à 20, qui coopèrent avec la languette mâle pour
réaliser la connexion électrique. Les lames se font face
deux à deux, respectivement 17, 19 et 18, 20. Les lames 17
et 18 sont portées chacune par une moitié du dessus de la
cage d'enfichage 2, repliée après découpe, de façon à être
sensiblement parallèle au fond 9 de la cage d'enfichage 2,
c'est-à-dire sensiblement parallèle aux lames 19 et 20
prélevées sur le fond 9.In Figures 5 and 6, the reference numbers
identical to those of FIGS. 1 to 4 designate elements
identical or technically equivalent. The main
differences between the embodiment of Figures 1 and 2
and that of FIGS. 5 and 6 reside in the structure of
the plug-in
Sur les figures 7 et 8, les chiffres de référence identiques à ceux des figures 1 à 6 désignent des éléments identiques ou techniquement équivalents.In Figures 7 and 8, the reference numbers identical to those of FIGS. 1 to 6 designate elements identical or technically equivalent.
Par rapport aux modes de réalisation des figures 1 à 4 d'une part, et 5 et 6 d'autre part, le troisième mode de réalisation du connecteur représenté aux figures 7 et 8 se distingue par la forme de l'onde et par la structure de la cage d'enfichage.Compared to the embodiments of Figures 1 to 4 on the one hand, and 5 and 6 on the other hand, the third mode of realization of the connector shown in Figures 7 and 8 distinguished by the shape of the wave and by the structure of the plug-in cage.
L'onde 4 présente, du côté de la cage d'enfichage 2 un bord
21 incliné sur le plan médian de la cage d'enfichage 2.
L'inclinaison du bord 21 est comprise entre 60 et 90° ;
elle est de préférence voisine de 80° environ.
La cage d'enfichage 2 est à quatre lames de connexion
électrique, comme dans le mode de réalisation des figures 5
et 6, et elle comporte aussi une languette 22 de
verrouillage mécanique. Cette languette occupe la partie
axiale du fond de la cage d'enfichage 2. Elle est articulée
sur la partie de la cage d'enfichage voisine de la zone de
transition 3, contrairement au mode de réalisation des
figures 1 à 4 où la languette est articulée au voisinage de
l'ouverture de la cage d'enfichage 2.The plug-in
De plus, sur ses quatre arêtes longitudinales, la cage
d'enfichage 2 est munie de lumières telles que 23 pour
faciliter sa mise en forme à partir d'un feuillard découpé
et plié.In addition, on its four longitudinal edges, the

réalisation particuliers n'y est nullement limitée mais

variante de réalisation dans le cadre et l'esprit de
l'invention. En particulier, le bloc de raccordement 1 a
été représenté sur les figures 1 à 6 avec deux ailes de
sertissage 6 de l'âme d'un câble, au centre du bloc 1, et
sur le côté droit deux ailettes 8 de maintien de l'isolant,
ou de la gaine du câble.The invention described with reference to three modes of
particular achievement is by no means limited to it but
on the contrary covers any modification of form and any
variant in the context and spirit of
the invention. In particular, the connection block 1 a
been shown in Figures 1 to 6 with two wings of
crimping 6 of the core of a cable, in the center of
Le bloc de raccordement 1 peut être prévu avec les ailettes
de sertissage à gauche. Il peut ainsi être prévu avec deux
ailettes de sertissage à droite et deux autres à gauche,
dans le cas où deux câbles doivent être sertis sur le même
connecteur. Ces deux câbles peuvent avoir des âmes de
section différente, les deux âmes étant serties ensemble
par les ailes de sertissage 6.The
Les ailettes 8 de maintien de l'isolant, ou de la gaine du
câble sont représentées symétriques car la disposition de
l'onde permet de prélever de la matière entre le bloc de
raccordement 1 et la cage d'enfichage 2 pour constituer une
ailette 8 assez longue pour être symétrique de l'autre
ailette 8. Cependant, cette disposition symétrique des
ailettes 8 n'est pas impérative et les ailettes 8 peuvent
être dissymétriques.The
Un objectif de l'invention est de réduire la distance entre
le bloc de raccordement 1 et la cage d'enfichage 2 tout en
gardant le même plan général de contact dans la cage
d'enfichage, et de sertissage, c'est-à-dire en conservant
la direction de l'effort d'enfichage dans le plan contenant
l'axe du conducteur serti dans le bloc de sertissage.An objective of the invention is to reduce the distance between
the
La forme de l'onde n'est pas limitée aux exemples décrits et représentés sur les figures et notamment sur les figures 4 et 8, où l'onde n'a qu'une alternance.The shape of the wave is not limited to the examples described and represented in the figures and in particular in the figures 4 and 8, where the wave has only one alternation.
En particulier, la forme de l'onde est susceptible d'être différente, par exemple à deux alternances. Dans les connecteurs de petites dimensions, il peut arriver que l'onde se déplie lors de l'extraction du contact. Pour éviter cet inconvénient, il est souhaitable de donner plus de résistance mécanique à l'onde. A cet effet, l'onde peut être inclinée sur le plan médian de la cage d'insertion passant par l'axe du conducteur, comme représenté sur les figures 7 et 8.In particular, the shape of the wave is likely to be different, for example with two half-waves. In the connectors of small dimensions, it can happen that the wave unfolds during contact extraction. For avoid this inconvenience, it is desirable to give more mechanical resistance to the wave. For this purpose, the wave can be inclined on the median plane of the insertion cage passing through the conductor's axis, as shown in the Figures 7 and 8.
