Description
La présente invention concerne un connecteur pour câble coaxialThe present invention relates to a connector for coaxial cable
On sait que dans le domaine des hautes fréquences les dispositifs connecteurs pour câbles doivent à la fois assurer la connexion sans perturber les caractéristiques électriques; tout en présentant une bonne résistance mécanique.It is known that in the high frequency domain the connector devices for cables must both ensure the connection without disturbing the electrical characteristics; while having good mechanical resistance.
En outre de tels connecteurs doivent souvent également présenter une étanchéité absolue, notamment dans le cas d'applications sous- marines où ils peuvent se trouver soumis à des pressions hydrostatiques élevées.In addition, such connectors must often also have absolute tightness, in particular in the case of underwater applications where they may be subjected to high hydrostatic pressures.
Dans les connecteurs connus, la fonction connexion électrique entre un câble coaxial classique et le connecteur lui-même se trouve dissociée de la fonction de reprise de l'effort mécanique s'exerçant au niveau du câble et du connecteur . A cet effet, on associe d'une part une armure ou une tresse métallique au câble, et d'autre part des moyens mécaniques classiques au connecteur, par exemple un serre-câble.In known connectors, the electrical connection function between a conventional coaxial cable and the connector itself is dissociated from the function of taking up the mechanical force exerted on the cable and the connector. For this purpose, we associate on the one hand a metal armor or braid to the cable, and on the other hand conventional mechanical means to the connector, for example a cable clamp.
De telles dispositions se révèlent d'une structure complexe, d'une géométrie encombrante, et d'un coût de réalisation élevé.Such arrangements prove to be of a complex structure, of bulky geometry, and of a high cost of production.
La Demanderesse a donc cherché à réaliser un connecteur apte à assurer simultanément la fonction connexion électrique et la fonction de reprise de l'effort mécanique tout en assurant une étanchéité absolue et une rigidité diélectrique élevée.The Applicant has therefore sought to produce a connector capable of simultaneously ensuring the electrical connection function and the mechanical force recovery function while ensuring absolute sealing and high dielectric strength.
L'invention porte donc sur un connecteur pour câble coaxial, ledit câble comprenant de l'intérieur vers l'extérieur un conducteur central ou âme, un revêtement électroniquement isolant, un conducteur externe et une gaine, caractérisé par le fait que ledit connecteur comporte une carcasse extérieure entourant un manchon-écran isolant disposé autour d'une attache conductrice dont l'extrémité arrière est liée au moyen d'une frette au conducteur externe dudit câble, ladite attache conductrice entourant elle même d'une part à son extrémité avant un conducteur annulaire débouchant à l'extrémité avant du connecteur et d'autre part à sa partie médiane deux pièces concentriques de sections coniques entre lesquelles est assujettie l'extrémité dudit revêtement électroniquement isolant, lesdites pièces coniques étant serrées au moyen d'un organe de serrage venant en butée sur une entretoise, une chemise isolante étant disposée entre ledit conducteur annulaire, ladite attache conductrice et une pièce annulaire liée à la partie avant de ladite carcasse extérieure et entourant l'extrémité avant du connecteur, une pièce isolante étant en outre disposée à l'extrémité avant dudit connecteur annulaire et une broche connectée à l'âme dudit câble, des canons isolants étant par ailleurs prévus autour de ladite âme dans la partie centrale du connecteur.The invention therefore relates to a connector for coaxial cable, said cable comprising from the inside to the outside a central conductor or core, an electronically insulating coating, an external conductor and a sheath, characterized in that said connector comprises a outer carcass surrounding an insulating screen sleeve arranged around a conductive fastener, the rear end of which is connected by means of a hoop to the external conductor of said cable, said conductive fastener itself surrounding on the one hand at its front end a conductor annular opening at the front end of the connector and on the other hand at its middle part two concentric pieces of conical sections between which is fixed the end of said electronically insulating coating, said conical pieces being clamped by means of a clamping member coming in abutment on a spacer, an insulating jacket being arranged between said annular conductor, said conductive fastener and an annular part linked to the front part of said outer carcass and surrounding the front end of the connector, an insulating part being further disposed at the front end of said annular connector and a pin connected to the core of said cable, insulating barrels being also provided around said core in the central part of the connector.
D'autres caractéristiques et avantages de l'invention ressortent de la description qui suit donnée à titre d'exemple purement illustratif mais nullement limitatif en référence aux dessins annexés dans lesquels :
- La figure 1 représente une structure de câble auquel est adapté le connecteur selon l'invention
- La figure 2 représente une vue extérieure du connecteur selon l'invention.
- Les figures 3A et 3B représentent en demi-coupe longitudinale le connecteur selon l'invention.
- FIG. 1 represents a cable structure to which the connector according to the invention is adapted
- FIG. 2 represents an external view of the connector according to the invention.
- Figures 3A and 3B show in longitudinal half-section the connector according to the invention.
On a donc représenté figure 1 une structure de câble 7 auquel est adapté le connecteur selon l'invention, structure d'ailleurs décrite par la Demanderesse dans la demande de brevet francais n° 24 14 243 du 10 janvier 1978 et dans la demande de premier certificat d'addition N° 24 47 081 du 18 janvier 1979 pour "Câble électrique à élément porteur longitudinal".FIG. 1 therefore shows a cable structure 7 to which the connector according to the invention is adapted, a structure moreover described by the Applicant in French patent application No. 24 14 243 of January 10, 1978 and in the application for the first certificate of addition N ° 24 47 081 of January 18, 1979 for "Electric cable with longitudinal support element".
Une telle structure comprend un conducteur central ou âme 1 formé par exemple de sept fils toronnés de cuivre rouge, non rétreint. Ce conducteur est entouré d'un revêtement électroniquement isolant formé de 6 cordes 2 de la marque "Cef" formées par de fines fibres de polyamide aromatique de la marque "Kevlar" commercialisée par Dupont de Nemours, imprégnées d'une résine durcissable et tressées. Ces cordes sont noyées dans un isolant 3 en polyéthylène non représenté par des hachures pour plus de clarté de la figure. Le conducteur externe est constitué par une tresse 4 de fils de cuivre rouge. L'ensemble est entouré d'une gaine 5 en polychlorure de vinyle ou en polyéthylène.Such a structure comprises a central conductor or core 1 formed for example of seven stranded wires of red copper, not shrunk. This conductor is surrounded by an electronically insulating coating formed of 6
Les figures 2, 3A et 3B représentent le connecteur selon l'invention du câble 7 arrivant à la partie arrière dudit connecteur.Figures 2, 3A and 3B show the connector according to the invention of the cable 7 arriving at the rear part of said connector.
Ce connecteur présente une forme générale cylindrique. Il comporte une carcasse extérieure métallique 10 solidarisée à une bride 11 percée par exemple de 6 alésages 12 aptes à recevoir les boulons de fixation du connecteur (non représentés). La carcasse 10 entoure un manchon-écran électriquement isolant 13. Ce manchon 13 entoure lui-même une attache conductrice 14 s'étendant sensiblement de la partie médiane à la partie avant du manchon-écran. Par ailleurs, un joint presse-étoupe extérieur 15 coopère avec des rondelles 16, l'ensemble étant disposé entre la partie arrière de la carcasse 10 et le manchon 13. Ce presse-étoupe 15 est serré au moyen d'un écrou extérieur évidé 17.This connector has a generally cylindrical shape. It comprises a metal
Ladite attache conductrice 14 est disposée par l'intermédiaire de son extrémité avant autour d'un conducteur annulaire 18 débouchant à l'extrémité avant du connecteur et, par l'intermédiaire de sa partie médiane, elle assujettit deux pièces de sections coniques concentriques 15 et 20.Said
De plus un joint presse-étoupe interne 21 coopère avec des rondelles 22, l'ensemble étant disposé entre la partie arrière du manchon 13 et le câble 7 ; ce joint est serré au moyen d'un écrou intérieur 23.In addition, an
Les figures montrent également une pièce de guidage 24 disposée autour du câble 7, à l'intérieur de l'évidement de l'écrou 17. Une telle pièce a pour objet d'éviter toute contrainte de flexion sur ledit câble.The figures also show a
La référence 25 désigne une pièce apte à assurer le serrage des pièces coniques 19 et 20, cette pièce 25 venant également en butée sur une entretoise 26 par l'intermédiaire d'une rondelle souple 27 ou d'un empilage de rondelles métalliques dont la longueur exacte est définie au moment du montage de la connexion et permet ainsi de rattraper le jeu au maximum.The
On a référencé en 28 une chemise isolante disposée entre le conducteur annulaire 18, l'attache 14 et une pièce 29 dite sortie du connecteur. Cette sortie 29 est fixée au moyen de vis 30 à la carcasse 10, des joints d'étanchéité 31 et 32 étant disposés dans des logements ménagés respectivement dans les parties avant de la carcasse et de ladite pièce de sortie 29.Reference is made at 28 to an insulating jacket disposed between the annular conductor 18, the
On voit en outre à l'avant du connecteur une pièce isolante 33 disposée entre le conducteur annulaire 18 et une broche 34 montée à l'intérieur du conducteur annulaire 18.There is also seen at the front of the connector an
Enfin des canons isolants tels que 35, 36 et 37 sont prévus au contact et autour de l'âme 1 du câble (non représentée) au centre du connecteur.Finally, insulating barrels such as 35, 36 and 37 are provided in contact with and around the core 1 of the cable (not shown) in the center of the connector.
La connexion des divers constituants du câble 7 au dispositif connecteur selon l'invention est effectuée de la façon suivante :
- Le câble 7 est introduit dans la partie arrière du connecteur.
- The cable 7 is introduced into the rear part of the connector.
Le conducteur central ou âme 1 (non apparent sur les figures) est connecté directement à la broche 34 de l'avant du connecteur. L'extrémité des'cordes 2 de Kevlar sont assujetties entre les pièces de section conique 19 et 20, un composé isolant polymérisable 38 étant avantageusement coulé dans des espaces définis par lesdites* pièces 19 et 20, l'attache 14 , la pièce 25, et les canons isolants 35 et 37, une canule 40 étant également prévue pour maintenir les cordes de Kevlar 2. En outre, cette canule 40 dont une extrémité est insérée sous la tresse 4 du câble a également pour but de renforcer mécaniquement ledit câble évitant ainsi son écrasement sous la pression exercée par-le joint 21. Elle assure également la continuité de l'écran et la conservation de l'impédance.The central conductor or core 1 (not visible in the figures) is connected directly to
On voit également que l'extrémité de la tresse 4 est frettée et soudée sur l'extrémité arrière de l'attache conductrice 14.It can also be seen that the end of the braid 4 is hooped and welded to the rear end of the
En ce qui concerne la gaine 5, elle est arrêtée sensiblement au niveau de l'extrémité de la canule 40 et maintenue par la frette de la tresse 4.As regards the
Si l'on considère maintenant l'avant du connecteur, on voit donc que le potentiel de l'âme 1 du câble est recueilli à la broche 34 et que le potentiel de la tresse 4 est recueilli au niveau du conducteur annulaire 18 par l'intermédiaire de l'attache conductrice 14.If we now consider the front of the connector, we therefore see that the potential of the core 1 of the cable is collected at
On voit donc que par sa structure le connecteur selon l'invention assure simultanément diverses fonctions :
- En premier lieu il permet à sa sortie d'obtenir trois potentiels séparés, à savoir le potentiel de l'âme 1 du câble, le potentiel de la tresse 4, et le potentiel de la
carcasse 10, tout en conservant l'impédance électrique du câble, l'écart entre lesdits potentiels pouvant être de 10 KV au moins.
- Firstly, it allows its output to obtain three separate potentials, namely the potential of the core 1 of the cable, the potential of the braid 4, and the potential of the
carcass 10, while retaining the electrical impedance of the cable, the difference between said potentials being at least 10 KV.
En outre la mise en oeuvre d'un manchon-écran 13 assure en plus de la séparation des potentiels la transmission de l'effort mécanique de compression, cet effort pouvant être au moins de 2000 kg.In addition, the use of a screen sleeve 13 ensures, in addition to the separation of the potentials, the transmission of the mechanical compression force, this force possibly being at least 2000 kg.
Par ailleurs, l'utilisation de joints et presse-étoupes permet d'assurer son étanchéité à des pressions extérieures de l'ordre de 100 bars minimum.Furthermore, the use of gaskets and cable glands makes it possible to seal it at external pressures of the order of 100 bars minimum.
Il trouve des applications particulièrement avantageuses dans les techniques haute fréquence sous marines.It finds particularly advantageous applications in high frequency underwater techniques.
Bien que le dispositif qui vient d'être décrit paraisse le plus avantageux pour la mise en oeuvre de l'invention dans une situation technique particulière, on comprendra que certaines modifications peuvent lui être apportées sans sortir du cadre de l'invention, certains de ses éléments pouvant être remplacés par d'autres susceptibles d'y assurer la même fonction technique.Although the device which has just been described seems the most advantageous for the implementation of the invention in a particular technical situation, it will be understood that certain modifications can be made to it without departing from the scope of the invention, some of its elements which can be replaced by others capable of ensuring the same technical function.
