The connector also comprises an impedance matching element (114) at the level of the connection between the conducting core (110) and the perpendicular element (112).

Description

La présente invention concerne le domaine de la connectique.The present invention relates to the field of connectors.

Plus précisément, la présente invention concerne le domaine des connecteurs de type coaxial.More specifically, the present invention relates to the field of coaxial connectors.

La présente invention trouve notamment application dans la connectique pour signaux de télévision, qu'il s'agisse du domaine de la télévision câblée, d'antennes collectives ou de réceptions satellites.The present invention finds particular application in the connectors for television signals, whether in the field of cable television, collective antennas or satellite reception.

Plus précisément encore, la présente invention trouve en particulier, mais non exclusivement, application dans la réalisation d'équipements tels que des commutateurs multi-satellites, multi-utilisateurs réalisés dans des ceintures métalliques pouvant être équipées d'un nombre important de connecteurs.More precisely still, the present invention finds in particular, but not exclusively, application in the production of equipment such that multi-satellite, multi-user switches made in metal belts that can be fitted with a large number of connectors.

On a illustré sur la figure 1, un exemple de réalisation connu d'une telle ceinture utilisant une connectique dénommée généralement de type "F" par les spécialistes. (Plus précisément sur la figure 1, on a illustré une ceinture classique équipée de connecteurs conformes à la présente invention).Illustrated in Figure 1, a known embodiment of a such a belt using a connector generally called "F" type by specialists. (More specifically in Figure 1, there is illustrated a classic belt fitted with connectors conforming to this invention).

Dans le cas des ceintures telles qu'illustrées sur la figure 1, deux types de connectique sont habituellement utilisés : les embases droites ou les embases coudées pour circuits imprimés.In the case of belts as illustrated in Figure 1, two types of connectors are usually used: straight sockets or angled bases for printed circuits.

On a illustré sur la figure 2, un exemple de réalisation d'embases droites. Celles-ci sont généralement conçues pour être fixées sur une paroi support 10 par vissage ou sertissage. Le dispositif de connexion illustré sur la figure 2 comprend un conducteur central 15 rectiligne apposé sur un circuit imprimé 20 portant l'électronique 30 associée, laquelle est schématisée sur la figure 2. Le dispositif du type illustré sur la figure 2 présente un inconvénient majeur : le fait que le circuit imprimé 20 se trouve dans l'axe de l'embase une fois le produit terminé. Ceci suppose en effet une mise en place manuelle de l'électronique et un nombre important de reprises de soudures, notamment pour raccorder la masse électrique au châssis. Illustrated in Figure 2, an embodiment of bases straight. These are generally designed to be fixed on a wall support 10 by screwing or crimping. The connection device illustrated on FIG. 2 comprises a rectilinear central conductor 15 affixed to a printed circuit 20 carrying the associated electronics 30, which is shown schematically in Figure 2. The device of the type illustrated in Figure 2 has a major drawback: the fact that the printed circuit 20 is located in the axis of the base once the product is finished. This supposes indeed manual installation of electronics and a significant number of re-welding, in particular to connect the electrical ground to the frame.

On a illustré sur la figure 3 un exemple de réalisation d'embases coudées.Illustrated in Figure 3 an embodiment of bases cubits.

Dans ce cas, le conducteur central du dispositif est muni à son extrémité destinée à être fixée sur un circuit imprimé, d'un tronçon 40 perpendiculaire à l'âme principale du conducteur central de connecteur, émergeant au centre d'une cage 42 liée à la masse et présentant de préférence quatre points de liaison 44 sur le circuit imprimé. Ces embases ont déjà rendu de grands services. Elles sont prévues notamment pour être soudées à la vague. Cependant, elles ne donnent pas toujours pleinement satisfaction.In this case, the central conductor of the device is provided with his end intended to be fixed to a printed circuit, of a section 40 perpendicular to the main core of the central connector conductor, emerging in the center of a cage 42 linked to the mass and having preferably four connection points 44 on the printed circuit. These bases have already done great service. They are intended in particular to be welded to the wave. However, they do not always give full satisfaction.

En particulier, ces embases s'avèrent complexes ; elles présentent généralement une mauvaise caractérisation en impédance car le coude à 90° formé au niveau du conducteur central présente une rupture d'impédance à certaines fréquences dépendantes de la dimension physique du connecteur ; et de nos jours, il n'est pas apparu possible d'opérer un sertissage de tels connecteurs d'où la nécessité de les maintenir sur le châssis par un ensemble rondelle plus écrou.In particular, these bases are complex; they present generally a poor impedance characterization because the elbow at 90 ° formed at the level of the central conductor has a break impedance at certain frequencies depending on the physical dimension the connector; and nowadays, it has not appeared possible to operate a crimping of such connectors, hence the need to keep them on the chassis by a washer and nut assembly.

L'objet de la présente invention est de proposer un nouveau connecteur performant d'un point de vue électrique et d'une grande facilité de mise en oeuvre, tant d'un point de vue fixation mécanique que raccordement électrique.The object of the present invention is to propose a new electrical connector with great ease of implementation, both from a mechanical fixing point of view and electrical connection.

Ce but est atteint dans le cadre de la présente invention, grâce à un connecteur du type coaxial notamment pour signaux de télévision comprenant une âme électriquement conductrice, un corps isolant qui entoure ladite âme et une enveloppe externe formant masse placée sur le corps isolant, ladite âme étant prolongée sur l'arrière du corps par un tronçon perpendiculaire conçu pour assurer une liaison sur un circuit imprimé, caractérisé par le fait que l'enveloppe externe comprend une jupe annulaire dirigée vers l'extrémité avant du connecteur, à l'opposé du tronçon, pour une fixation par sertissage.This object is achieved in the context of the present invention, thanks to a connector of the coaxial type in particular for television signals comprising an electrically conductive core, an insulating body which surrounds said core and an external envelope forming a mass placed on the insulating body, said core being extended on the rear of the body by a perpendicular section designed to provide a link on a circuit printed, characterized in that the outer envelope comprises a skirt annular directed towards the front end of the connector, opposite the section, for fixing by crimping.

Selon une autre caractéristique avantageuse de l'invention, le connecteur comprend un élément d'adaptation d'impédance au niveau de la zone de liaison âme/tronçon. According to another advantageous characteristic of the invention, the connector includes an impedance matching element at the core / section connection area.

Le dispositif de connexion 100 conforme à la présente invention, illustré sur les figures 4 et suivantes, comprend un organe central 110 électriquement conducteur et une douille 120 externe électriquement conductrice formant masse, séparés par un corps intercalaire 130 électriquement isolant.The connection device 100 according to the present invention, illustrated in Figures 4 and following, includes a central member 110 electrically conductive and an electrically 120 external socket conductive forming a mass, separated by an intermediate body 130 electrically insulating.

Le dispositif est conçu pour un raccordement, avec un dispositif de connexion complémentaire, au niveau d'une extrémité 102 dite "avant", laquelle émerge à l'extérieur d'un boítier support.The device is designed for connection, with a device for additional connection, at one end 102 called "front", which emerges outside of a support case.

Ainsi au niveau de cette extrémité avant, le conducteur central 110 se présente de préférence sous la forme d'une douille pour la connexion avec un élément mâle complémentaire.Thus at this front end, the central conductor 110 preferably in the form of a socket for connection with a complementary male element.

Cependant en variante au niveau de cette extrémité avant, on peut prévoir une broche mâle pour la connexion avec un élément conducteur femelle complémentaire. However as a variant at this front end, it is possible to provide a male pin for connection with a conductive element complementary female.

Bien entendu, la structure du corps isolant intercalaire 130 doit être adapté en conséquence.Of course, the structure of the insulating intermediate body 130 must be adapted accordingly.

Comme on le voit sur les figures 4 et suivantes, dans le cadre de l'invention, le conducteur central 110 émerge largement sur l'extrémité "arrière" 104 du dispositif.As can be seen in Figures 4 and following, in the context of the invention, the central conductor 110 emerges widely at the end "rear" 104 of the device.

Et au niveau de cette extrémité arrière, le conducteur central 100 est prolongé par un tronçon rectiligne 112 qui lui est orthogonal.And at this rear end, the central conductor 100 is extended by a rectilinear section 112 which is orthogonal thereto.

La longueur de ce tronçon 112, également réalisé en un matériau électriquement conducteur, qui s'étend radialement par rapport à l'axe O-O de la douille 120, est supérieure au plus grand rayon de la douille 120 pour permettre le raccordement de l'extrémité libre du tronçon 112 sur une plage électriquement conductrice d'un circuit imprimé 50 s'étendant parallèlement à cet axe O-O.The length of this section 112, also made of a material electrically conductive, which extends radially with respect to the axis O-O of socket 120, is greater than the largest radius of socket 120 for allow the free end of section 112 to be connected to a beach electrically conductive of a printed circuit 50 extending in parallel to this axis O-O.

Par ailleurs au niveau de la zone de jonction entre le conducteur central 110 et le tronçon de prolongation 112, il est prévu dans le cadre de l'invention un élément d'adaptation d'impédance ou "stub" d'adaptation, de type capacitif, référencé 114.Furthermore at the junction zone between the conductor central 110 and the extension section 112, it is provided as part of the invention an impedance matching element or matching "stub", capacitive type, referenced 114.

De préférence dans le cadre de l'invention, ce stub d'adaptation est formé d'une cosse ou anneau venu de matière sur le tronçon 112, plié à 90° de la direction longitudinale du tronçon et pincé sur l'extrémité arrière du conducteur central 110.Preferably within the framework of the invention, this adaptation stub is formed of a terminal or ring made of material on the section 112, bent at 90 ° from the longitudinal direction of the section and pinched on the rear end of the central conductor 110.

Ainsi, l'élément 114, qui se présente à l'origine sous forme d'un élément en U est pincé sur l'extrémité arrière du conducteur 110 par pliage de ses ailes.Thus, element 114, which originally appears as a U-shaped element is clamped on the rear end of the conductor 110 by bending of his wings.

On notera qu'une fois mise en place la cosse définit un élargissement du conducteur central 110 sur son extrémité arrière, propre à générer l'adaptation d'impédance de type capacitif recherchée.Note that once in place the terminal defines a widening of the central conductor 110 on its rear end, suitable for generate the desired capacitive type impedance matching.

On notera également qu'une fois installé le tronçon 112 est placé en retrait de l'extrémité de la partie du conducteur central 110 émergeant sur l'arrière de la douille 120, par exemple s'étend ainsi sensiblement à mi longueur de cette partie.It will also be noted that once installed the section 112 is placed in removal of the end of the part of the central conductor 110 emerging from the rear of the socket 120, for example thus extends substantially at mid length of this part.

De préférence la surface combinée de la partie du conducteur central 110 et de la cosse 114 située sur l'arrière du tronçon 112 est comprise entre 6mm2 et 24mm2, avantageusement de l'ordre de 12mm2, la longueur L1 de cette surface étant comprise entre 2mm et 6mm avantageusement de l'ordre de 4mm, tandis que sa largeur L2 est comprise entre 2mm et 5mm, avantageusement de l'ordre de 3mm.Preferably the combined surface of the part of the central conductor 110 and of the terminal 114 located on the rear of the section 112 is between 6mm 2 and 24mm 2 , advantageously of the order of 12mm 2 , the length L1 of this surface being advantageously between 2mm and 6mm of the order of 4mm, while its width L2 is between 2mm and 5mm, advantageously of the order of 3mm.

La douille 120 peut également faire l'objet de nombreuses variantes de réalisation. Selon le mode de réalisation préférentiel illustré sur les figures annexées, la douille 120 est formée essentiellement de deux fûts 122, 124, coaxiaux et adjacents définissant respectivement l'extrémité avant 102 et l'extrémité arrière 104 du dispositif. Le fût arrière 104 présente un diamètre supérieur au fût avant 122. Il est ainsi défini au niveau de la zone de liaison entre les deux fûts 122, 124 un décrochement de géométrie annulaire 126 dirigé vers l'avant du dispositif.The socket 120 can also be the subject of many variants of achievement. According to the preferred embodiment illustrated on the attached figures, the socket 120 is formed essentially of two barrels 122, 124, coaxial and adjacent respectively defining the front end 102 and the rear end 104 of the device. The rear shaft 104 has a diameter greater than the barrel before 122. It is thus defined at the level of the zone of connection between the two barrels 122, 124 a drop in geometry annular 126 directed towards the front of the device.

A ce niveau, la douille 120 est munie d'une jupe cylindrique 125 centrée autour de l'axe O-O et dirigée vers l'avant du dispositif. Cette jupe annulaire 125 est adaptée pour assurer la fixation du dispositif sur une paroi support 10 par sertissage. Pour cela, il suffit, le dispositif étant engagé dans un alésage de la paroi support 10 présentant un diamètre complémentaire du diamètre externe de la jupe 125, par l'extrémité avant 102, de sertir la jupe 125 sur la paroi 10 pour pincer celle-ci entre le sertissage résultant de la jupe 125 et le décrochement 126.At this level, the socket 120 is provided with a cylindrical skirt 125 centered around the axis O-O and directed towards the front of the device. This skirt ring 125 is adapted to secure the device to a wall support 10 by crimping. For this, it suffices, the device being engaged in a bore in the support wall 10 having a complementary diameter of the outer diameter of the skirt 125, by the front end 102, of crimping the skirt 125 on the wall 10 to pinch it between the crimping resulting from the skirt 125 and the recess 126.

De préférence, la douille 120 et plus précisément son fût arrière 124 est muni par ailleurs d'un pion radial 140 conçu pour assurer la double fonction de positionnement mécanique au niveau du circuit imprimé et de rappel de masse électrique/mécanique.Preferably, the socket 120 and more precisely its rear barrel 124 is also provided with a radial pin 140 designed to ensure double mechanical positioning function on the printed circuit and electrical / mechanical mass recall.

Ce pion de positionnement 140 peut faire l'objet de nombreuses variantes de réalisation. Il est de préférence rapporté sur la douille 120 et fixé sur celle-ci en étant serti ou vissé dans un alésage complémentaire 128 formé radialement sur la périphérie extérieure du fût 124.This positioning pin 140 can be the subject of numerous variant embodiments. It is preferably attached to the socket 120 and fixed on it by being crimped or screwed in a complementary bore 128 formed radially on the outer periphery of the barrel 124.

Selon une variante intéressante de l'invention, le pion 140 est formé d'un fourreau fendu longitudinalement, à la façon d'une goupille, et engagé élastiquement dans un alésage borgne complémentaire 128 débouchant sur la surface extérieure du fût 124. According to an interesting variant of the invention, the pin 140 is formed a sheath split longitudinally, like a pin, and engaged elastically in a complementary blind bore 128 leading to the exterior surface of the barrel 124.

On notera que de préférence, le pion 140 s'étend dans la même direction radiale que le tronçon de connexion 112.It will be noted that preferably, the pin 140 extends in the same radial direction than the connecting section 112.

On a schématisé sur la figure 8, 16 dispositifs de connexion conformes à la présente invention répartis sur une ceinture métallique. Les modalités de fixation par sertissage par l'avant autorisées grâce à l'invention permettent un montage aisé sur une telle ceinture malgré le nombre important de connecteurs.16 connection devices have been shown diagrammatically in FIG. 8 in accordance with the present invention distributed over a metal belt. The methods of fixing by crimping from the front authorized thanks to the invention allow easy mounting on such a belt despite the number important of connectors.

On notera que le tronçon rectiligne 112 qui prolonge électriquement, à angle droit, le conducteur central 110 possède une extrémité 113 en pointe (voir figure 6). Une telle extrémité en pointe facilite l'introduction du tronçon 112 dans le trou complémentaire du circuit imprimé 50 prévu pour l'accueillir.It will be noted that the rectilinear section 112 which extends electrically, at a right angle, the central conductor 110 has an end 113 in tip (see Figure 6). Such a pointed end facilitates the introduction of the section 112 in the complementary hole of the printed circuit 50 provided for welcome him.

Le dispositif de connexion conforme à la présente invention présente en outre les avantages suivants par rapport à l'état de la technique connu:

  • facilité du montage mécanique sur des ceintures fermées et sur plusieurs côtés, liée au sertissage par l'avant,
  • amélioration des performances électriques (impédance et rappel de masse électrique), et
  • amélioration du processus industriel : la ceinture équipée de ces connecteurs est prévue pour passer la soudure à la vague en même temps que le circuit imprimé de la carte électronique. Ce passage à la vague garantit ainsi la soudure des composants, le raccordement électrique des connecteurs et la fixation mécanique de la carte électronique dans le châssis.
The connection device according to the present invention also has the following advantages over the known state of the art:
  • ease of mechanical mounting on closed belts and on several sides, linked to crimping from the front,
  • improvement of electrical performance (impedance and recall of electrical ground), and
  • improvement of the industrial process: the belt fitted with these connectors is designed to pass wave soldering at the same time as the printed circuit of the electronic card. This passage to the wave thus guarantees the soldering of the components, the electrical connection of the connectors and the mechanical fixing of the electronic card in the chassis.

Bien entendu la présente invention n'est pas limitée au mode de réalisation particulier qui vient d'être décrit, mais s'étend à toutes variantes conformes à son esprit.Of course, the present invention is not limited to the mode of particular embodiment which has just been described, but extends to all variants conform to his spirit.

Ainsi en variante, on peut envisager non pas de réaliser l'élément d'adaptation d'impédance 114 sous forme d'une cosse sertie comme indiqué précédemment, mais sous forme d'un élément respectant les caractéristiques précitées, notamment dimensionnelles, et soit venu de matière avant le tronçon 112 et soudé sur l'extrémité arrière du conducteur central 110, soit venu de matière sur l'extrémité arrière du conducteur central 110, sur lequel est par ailleurs soudé un coude du tronçon 112.As a variant, it is not possible to envisage making the element impedance matching 114 in the form of a terminal crimped as indicated above, but in the form of an element respecting the aforementioned characteristics, in particular dimensional, and came from material before section 112 and welded to the rear end of the conductor central 110, either integral with the rear end of the conductor central 110, on which is also welded an elbow of the section 112.
