L'invention s'applique plus particulièrement aux éléments de connecteurs coaxiaux pour la télévision numérique haute résolution de type BNC, de tels éléments de connecteurs étant par exemple utilisés pour réaliser des cordons coaxiaux reliant différents modules radiofréquences fixés dans une baie. L'invention n'est toutefois pas limitée à ce type de connecteur particulier.The present invention relates to a coaxial connector element. The invention applies more particularly to coaxial connector elements for BNC type high-resolution digital television, such connector elements being for example used to produce coaxial cables connecting different radio frequency modules fixed in a rack. The invention is however not limited to this type of particular connector.
La surface de préhension des éléments de connecteur connus pour ce type d'application n'est définie que par le bouchon. Il en résulte une surface de préhension d'étendue relativement restreinte, ce qui rend délicate toute manipulation dans un environnement dense ou en aveugle d'un cordon coaxial comportant un tel élément de connecteur, un tel environnement étant par exemple une baie pour la télévision numérique haute résolution.The gripping surface of known connector elements for this type of application is defined only by the plug. This results in a gripping surface of relatively small extent, which makes it difficult to manipulate in a dense or blind environment a coaxial cord comprising such a connector element, such an environment being for example a rack for digital television. high resolution.

Comme on peut le voir, le bouchon creux 3 comporte une partie avant 11, dans laquelle une rainure hélicoïdale 12 permettant la fixation du bouchon à un élément de connecteur complémentaire par baïonnette est aménagée. Le bouchon 3 comporte également une partie arrière 13 sur la surface extérieure de laquelle sont aménagés des reliefs 14 et 15. Dans l'exemple décrit, deux clavettes 14 sont réalisées d'une seule pièce avec la surface extérieure de la partie arrière 13 du bouchon 3 et sont diamétralement opposées l'une par rapport à l'autre, mais ces deux clavettes pourraient être disposées différemment sur ladite surface extérieure.As can be seen, the
La partie arrière 13 du bouchon 3 comporte encore une bague 15 s'étendant dans l'exemple décrit sur le pourtour de la surface extérieure de cette partie arrière 13 du bouchon 3.The
La partie arrière 13 comporte encore, comme représenté à la
Le bouchon 3 est par exemple réalisé par injection de matière plastique transparente, par exemple en polycarbonate.The
Le manchon 2 définit un logement permettant de recevoir la partie arrière 13 du bouchon 3 et un câble coaxial 18, comme représenté à la
Dans l'exemple décrit, la surface intérieure de la partie avant 19 du manchon 2 comporte deux décrochements 20 s'étendant longitudinalement et une gorge annulaire 21 s'étendant sur le pourtour de la surface intérieure de la partie avant 19 du manchon.In the example described, the inner surface of the
Le manchon 2 est par exemple réalisé en matière plastique flexible, par exemple en polyuréthane et cette matière plastique peut comporter un additif colorant, pour ajouter au manchon une fonctionnalité de codage, en plus de celles de protection du câble coaxial et d'accompagnement des mouvements de ce dernier.The
Le manchon 2 et le bouchon 3 peuvent être tous deux réalisés en matière plastique comportant des adjuvants phosphorescents avantageusement choisis en adéquation avec la matière plastique correspondante.The
Comme on peut le voir sur la
Le manchon 2 peut être avantageusement agencé de telle sorte que sa surface extérieure définisse une partie de préhension 22, cette partie de préhension 22 étant par exemple obtenue par moletage ou par l'aménagement d'une zone rugueuse.The
Selon le premier mode de réalisation de l'invention, lors de l'assemblage de l'élément de connecteur 1, le manchon 2 et le bouchon 3 sont préalablement fixés l'un à l'autre, de façon à être rendu indémontables par la suite par un utilisateur. Comme représenté à la
L'ensemble ainsi obtenu est ensuite monté sur le corps 4 et chaque patte élastique 16 vient en appui dans la rainure annulaire 10 pour maintenir ledit ensemble sur le corps 4.The assembly thus obtained is then mounted on the
L'invention n'est pas limitée à un nombre particulier de clavettes 14, de bague 15, de décrochements 20, de gorge 21, de pattes élastique 16 et de rainure 10 et à une forme particulière de ces derniers.The invention is not limited to a particular number of

L'invention n'est pas limitée aux exemples qui viennent d'être décrits.The invention is not limited to the examples which have just been described.
Bien que les exemples décrits concernent un élément de connecteur à relier à un élément de connecteur correspondant par une liaison à baïonnette pour réaliser un connecteur de type BNC, l'invention peut s'appliquer à des éléments de connecteurs à d'autres types de liaison.Although the examples described relate to a connector element to be connected to a corresponding connector element by a bayonet connection to make a BNC type connector, the invention can be applied to elements of connectors to other types of connection. .
Bien que dans les exemples décrits, l'élément de connecteur ne comporte qu'un seul contact central, l'invention n'exclut pas la présence de par exemple deux contacts centraux pour l'élément de connecteur.Although in the examples described, the connector element has only one central contact, the invention does not exclude the presence of for example two central contacts for the connector element.

Dans cet exemple, le bouchon 3 et le manchon 2 peuvent être réalisés d'une seule pièce, comme décrit selon le deuxième mode de réalisation de l'invention, ou être réalisés en deux pièces distinctes fixées l'une à l'autre, comme décrit selon le premier mode de réalisation de l'invention.In this example, the
Comme représenté, le bouchon 3 et le manchon 2 comportent dans l'exemple décrit une protubérance 40 s'étendant selon l'axe longitudinal X. Cette protubérance 40 peut s'étendre sur toute la longueur du manchon et/ou du bouchon ou sur une partie seulement de ces dernières. La protubérance 40 s'étend dans l'exemple décrit de façon continue mais pourrait, en variante, s'étendre de façon discontinue.As shown, the
Comme représenté sur la
Toujours dans l'exemple illustré, le bouchon 3 et le manchon 2 présentent un profil ovoïde ou elliptique.Still in the illustrated example, the
On va maintenant décrire le corps 4 en référence à la
Comme on peut le voir, ce dernier comporte une portion médiane 45 à l'intérieur de laquelle est définie une gorge principale 43 qui s'étend dans l'exemple décrit sur tout le pourtour de l'axe longitudinal (X) du corps. Une gorge secondaire 44 est ménagée dans cette gorge principale 43, à l'arrière de celle-ci.As can be seen, the latter comprises a
Comme représenté sur la
La bague plate 50 constitue un arrêt en translation arrière de la bague élastique 48, empêchant une fois l'assemblage réalisé la bague élastique 48 de sortir de la gorge principale 43.The
Comme représenté sur les
L'invention permet d'offrir une solution plus économique aux solutions connues pour améliorer la préhension d'un cordon coaxial en simplifiant le montage en usine de l'élément de connecteur, en ayant recours à moins de pièces détachées pour réaliser l'élément de connecteur et en présentant une solution allégée en poids.The invention makes it possible to offer a more economical solution to known solutions for improving the grip of a coaxial cord by simplifying the assembly of the connector element in the factory, by using fewer spare parts to produce the element. connector and presenting a solution lightened by weight.
L'invention permet en outre l'utilisation du même bouchon et/ou du même manchon pour différents diamètres de câbles coaxiaux.The invention further allows the use of the same plug and / or the same sleeve for different diameters of coaxial cables.
