Description
L'invention concerne un dispositif de connexion mâle pour connexion électrique à une prise femelle, notamment du type allume-cigare de véhicule automobile, destiné à s'adapter à différents diamètres de prise femelle, compris entre un diamètre minimum et un diamètre maximum, ledit dispositif de connexion mâle comportant :
- un manchon interne,
- un manchon externe entourant le manchon interne,
- au moins une patte de maintien disposée à l'extérieur du dispositif de connexion mâle,
- un dispositif d'écartement permettant d'écarter radialement la patte de maintien pour l'adaptation au diamètre de la prise femelle.
- an inner sleeve,
- an outer sleeve surrounding the inner sleeve,
- at least one retaining lug disposed outside the male connection device,
- a spacer device for radially spacing the retaining lug for adaptation to the diameter of the socket.
Il existe de nombreux appareils électriques ou électroniques tels que des appareils électroménagers, des équipements de télécommunication, des appareils audio, des appareils vidéo, etc, destinés à être connectés à une prise femelle, notamment du type allume-cigare de véhicule automobile. Le diamètre de ces prises allume-cigare, n'étant pas un standard mondial, il dépend du pays de fabrication du véhicule. Par exemple, les véhicules fabriqués en Europe sont généralement dotés d'une prise allume-cigare dont le diamètre est supérieur à celui des prises allume-cigare des véhicules fabriqués aux Etats-Unis et au Japon.There are many electrical devices or electronic devices such as household appliances, telecommunication equipment, audio equipment, video devices, etc., intended to be connected to a socket female, in particular of the type cigarette lighter of a motor vehicle. The diameter of these cigarette lighter plugs, not being a standard worldwide, it depends on the country of manufacture of the vehicle. For example, vehicles manufactured in Europe are generally equipped with a cigar lighter plug whose diameter is greater than that of the cigarette lighter plugs for vehicles manufactured in the United States and Japan.
Un dispositif de connexion mâle adaptable correspondant au préambule de la revendication 1 à différents diamètres de prise femelle allume-cigare est connu du brevet GB2293054A. Ce dispositif est constitué d'un manchon interne et d'un manchon externe. Le manchon externe est pourvu d'au moins une patte de maintien susceptible de s'écarter latéralement d'une position initiale par un dispositif d'écartement, lorsque l'un des manchons coulisse par rapport à l'autre selon un mouvement relatif longitudinal. Cet écartement provoque alors l'augmentation du diamètre extérieur du dispositif de connexion mâle jusqu'à atteindre le diamètre adéquat pour maintenir ledit dispositif dans la prise allume-cigare. L'adaptation du dispositif de connexion mâle au diamètre de la prise allume-cigare résulte donc d'un mouvement de glissement longitudinal d'un manchon dudit dispositif par rapport à l'autre, ce mouvement étant dans le prolongement des mouvements d'insertion et d'extraction dudit dispositif.An adaptable male connection device corresponding to the preamble of claim 1 to different cigarette lighter socket diameters is known from the patent GB2293054A. This device consists of an internal sleeve and an outer sleeve. The outer sleeve is provided with at least one holding lug that may move laterally away from a initial position by a spacer device, when one of the sleeves slide relative to each other in a relative motion longitudinal. This spacing then causes the increase of outer diameter of the male connection device up reach the correct diameter to maintain the device in the cigarette lighter plug. Adaptation of the connection device male to the diameter of the cigarette lighter socket therefore results from a longitudinal sliding movement of a sleeve of said device compared to the other, this movement being an extension of the insertion and extraction movements of said device.
Ce dispositif de connexion mâle présente au moins un inconvénient majeur. En effet, à chaque insertion/extraction dudit dispositif, l'écartement de la patte de maintien est susceptible d'être modifié. Par conséquent, l'adaptation du diamètre dudit dispositif de connexion mâle au diamètre de la prise femelle doit être réalisée à chaque nouvelle connexion.This male connection device has at least one major disadvantage. Indeed, at each insertion / extraction of said device, the spacing of the retaining lug is likely to be modified. Therefore, the adaptation of the diameter of the male connection device to the diameter of the socket must be performed at each new connection.
Un objet de la présente invention est de remédier dans une large mesure à cet inconvénient et de prévoir un dispositif de connexion mâle permettant de connecter un appareil électrique ou électronique à une prise femelle, notamment du type allume-cigare, de façon fiable, de telle sorte que le diamètre dudit dispositif puisse être adapté au préalable au diamètre de la prise femelle.An object of the present invention is to remedy in a large measure to this disadvantage and to provide a device for male connection for connecting an electrical appliance or electronic to a female socket, in particular of the cigarette lighter type, reliably, so that the diameter of said device can be adapted in advance to the diameter of the socket.
Pour cela, un dispositif du genre mentionné dans le
préambule est caractérisé en ce que :
Ce dispositif rotatif d'écartement présente l'avantage d'être ajustable au préalable au diamètre de la prise femelle pour éviter à l'utilisateur d'effectuer cet ajustement à chaque nouvelle connexion. Dans ce but, il est prévu un dispositif de blocage du dispositif d'écartement rotatif pour bloquer la rotation d'un manchon par rapport à l'autre.This rotary spacing device has the advantage of being adjustable in advance to the diameter of the socket to avoid the user to make this adjustment at each new connection. For this purpose, a device for blocking the rotary spacing device to block rotation of a sleeve relative to each other.
Un autre objet de la présente invention est de prévoir un dispositif de connexion mâle moins sensible aux éventuels désajustements occasionnés par de multiples insertions/extractions. En effet, l'adaptation du diamètre du dispositif de connexion mâle selon l'invention nécessitant un mouvement de rotation relatif entre le manchon interne et le manchon externe dudit dispositif, la probabilité pour que l'écartement se dérègle lors d'une action d'insertion (resp. d'extraction) dudit dispositif, dans (resp. de) la prise femelle est très faible, ces actions d'insertion/extraction s'effectuant lors de mouvements longitudinaux ne faisant pas appel à un mouvement de rotation.Another object of the present invention is to provide a male connection device less sensitive to potential misalignments caused by multiple insertions / extractions. Indeed, the adaptation of the diameter of the male connection device according to the invention requiring a relative rotational movement between the inner sleeve and the outer sleeve of said device, the probability that the gauge will go wrong during an action insertion (or extraction) of said device, into (or from) the socket is very small, these actions insertion / extraction during movements longitudinal not requiring rotation.
La description suivante, faite en regard des dessins ci-annexés, le tout donné à titre d'exemple non limitatif fera bien comprendre comment l'invention peut être réalisée.The following description, made next to the drawings attached hereto, all given as a non-restrictive example will do well understand how the invention can be realized.
La figure 1 représente une vue en perspective éclatée du dispositif de connexion mâle selon un mode de réalisation préféré de l'invention.FIG. 1 represents an exploded perspective view of the male connection device according to one embodiment preferred embodiment of the invention.
La figure 2 représente une vue en perspective du dispositif de connexion mâle selon le mode de réalisation préféré de l'invention.Figure 2 shows a perspective view of the male connection device according to the preferred embodiment of the invention.
La figure 3 représente en A, B, C et D quatre vues du dispositif de connexion mâle selon le mode de réalisation préféré de l'invention.Figure 3 shows in A, B, C and D four views of male connection device according to the preferred embodiment of the invention.
La figure 4 représente ces mêmes vues pour une valeur différente de diamètre de prise femelle.Figure 4 shows these same views for a value different of female socket diameter.
La figure 5 représente une vue en perspective éclatée d'une variante du mode de réalisation préféré selon l'invention.FIG. 5 represents an exploded perspective view of a variant of the preferred embodiment according to the invention.
La figure 6 représente une vue en perspective éclatée d'une autre variante du mode de réalisation préféré selon l'invention.Figure 6 shows an exploded perspective view another variant of the preferred embodiment according to the invention.
Le dispositif selon le mode de réalisation préféré
représenté à la figure 1 comporte un manchon interne 10, un manchon
externe 12 entourant le manchon interne 10, au moins une patte de
maintien 14 disposée à l'extérieur du manchon externe 12, la patte
de maintien 14 pouvant être conductrice. Un dispositif rotatif
d'écartement 16, solidaire du manchon interne 10, permet d'écarter
radialement la patte de maintien 14 d'une position initiale, lors
d'un mouvement relatif de rotation entre les manchons interne 10 et
externe 12. Pour cela, le dispositif rotatif d'écartement 16,
comporte un élément de came 18 présentant un profil de came, de
sorte que la patte de maintien 14, solidaire du manchon externe 12,
s'écarte de sa position initiale sous l'action de l'élément de came
18 afin d'adapter le diamètre externe du dispositif de connexion
mâle au diamètre interne de la prise femelle 17 et les maintenir en
contact mécanique et électrique après insertion. L'extrémité du
dispositif de connexion mâle comporte un élément électriquement
conducteur 19 destiné à coopérer avec un élément conducteur de la
prise femelle pour assurer un premier contact électrique. Un
deuxième contact électrique est réalisé sur les parois latérales
des parties mâle et femelle du dispositif de connexion. Pour cela,
il est prévu un dispositif métallique 21 élastiquement pressé vers
l'extérieur du manchon interne 10 par un ressort de rappel 15 et
coulissant par des ouvertures pratiquées dans ledit manchon 10. Un
circuit imprimé 11 assure l'interface entre les premier et deuxième
contacts décrits ci-dessus et les circuits électriques de
l'appareil que l'on désire connecter à la prise femelle 17. Selon
le mode de réalisation choisi, l'écartement de la patte de maintien
14 sous l'action de la came 18 peut être obtenu par différents
moyens. Si l'elasticité naturelle du matériau ne permet pas
d'obtenir l'écartement voulu, on pourra prévoir un moyen de rappel
élastique (non représenté).The device according to the preferred embodiment
shown in FIG. 1 comprises an
Les vues montrées en A, B, C et D aux figures 3 et 4
permettent de bien comprendre le mécanisme d'écartement de la patte
de maintien 14 lors de la rotation de l'élément de came 18 par
rapport au manchon externe 12.The views shown in A, B, C and D in Figures 3 and 4
make it possible to understand the mechanism of the
A la figure 3, la vue montrée en A représente une
section selon le plan [C-C] de la vue représentée en B. La vue
montrée en D représente une section selon le plan [B-B] de la vue
représentée en B. La vue montrée en C représente une section selon
le plan [D-D] de la vue représentée en D. Un dispositif de blocage
13 constitué d'une première série de dents sur le pourtour
extérieur du manchon interne 10 et d'une deuxième série de dents
sur le pourtour intérieur du manchon externe 12 est représenté en C
aux figures 3 et 4. Ce dispositif de blocage à crans d'arrêt 13
permet de maintenir l'écartement de la patte 14. Un agrandissement
du détail des crans de blocage 13 permet de bien comprendre comment
les manchons 10 et 12 coopèrent pendant la rotation de la came 18.
La figure 4 représente les mêmes vues que la figure 3, les manchons
10 et 12 ayant subit une rotation d'un angle α l'un par rapport à
l'autre. On voit donc à la figure 4 comment la patte 14 se soulève
sous l'action de la came 18 pour faire varier le diamètre du
dispositif de connexion mâle.In FIG. 3, the view shown in A represents a
section along the plane [C-C] of the view represented in B. The view
shown in D represents a section along the plane [B-B] of the view
represented in B. The view shown at C represents a section according to
the plane [D-D] of the view represented in D.
A titre de variante, la figure 5 représente un mode de
réalisation selon l'invention dans lequel la patte de maintien 14
est disposée longitudinalement sur le manchon externe 12. Le
dispositif selon un autre mode de réalisation représenté à la
figure 6 comporte les mêmes élements que celui représenté à la
figure 5, à la différence que les rôles des manchons externe 20 et
interne 22 sont inversés par rapport à la figure 5 et que le
dispositif comprend un élément supplémentaire, un moyen de rappel
élastique (non représenté) destiné à maintenir la patte 24 dans une
position initiale formant un angle avec l'axe du manchon interne 22
correspondant à un diamètre maximum de prise femelle 25. Le
dispositif d'écartement rotatif 26, solidaire du manchon externe
20, comporte un élément de came 28 au contact duquel l'angle formé
par la patte de maintien 24 et l'axe du manchon interne 22, diminue
pour adapter le dispositif de connexion mâle à un diamètre
inférieur de prise femelle.As a variant, FIG.
embodiment according to the invention in which the
Bien entendu, l'invention n'est pas limitée aux modes
de réalisations qui viennent d'être décrits et représentés.
D'autres variantes de mode de réalisation de l'invention
apparaítront à l'homme de l'art par exemple en ce qui concerne la
forme de la patte de maintien 14, le profil de l'élément de came
18, ou le système de blocage à crans d'arrêt 13, ces variantes ne
sortant pas du cadre de l'invention.Of course, the invention is not limited to the modes
of achievements that have just been described and represented.
