Definitions
- the subject of the invention is a connector for coaxial cables, especially for high frequency ones in use in telecommunications or cable television.
- Impedance is directly related to dimensions of the central conductor, of the conductor outside and at the dielectric. If the cables have a constant section over their entire length, this section is sometimes modified where the connector is fixed, especially if the external conductor has to be deformed to ensure electrical contact and cable retention. Modifying cable dimensions introduces a defect impedance which must be compensated in the connector. This compensation is not adjustable. It is therefore not valid only for a value of the impedance fault well precise, difficult to achieve during assembly of the connector on the cable.
- the object of the invention is a connector for coaxial cables which allows to fix the cable by deforming the external conductor (which provides electrical contact and fixing the connector) automatically reproducible without the need for precise measurements or subjective estimates during installation, or tools special.
- the object of the present invention is to provide a method of connection for coaxial cables which remedies these disadvantages and thanks to which the deformation of the conductor outside of the cable is always the same.
- the method according to the invention intended for the connection of coaxial cables provided with an inner conductor and an outer conductor separated by a dielectric, by connection of a front body intended to fix the cable and of a rear body, while a device keeps the cable in position so as to cause a reproducible deformation of the external conductor, involves the use of a ferrule intended to hold the cable, and of a socket which cooperate to allow axial movement over a distance determined of the ferrule and the cable relative to the socket.
- the deformation of the external conductor is caused and determined by a frontal plane of said socket.
- This connector for cables coaxial provided with an inner conductor and a external conductor separated by a dielectric, comprising a front body intended to fix the cable in the connector and a rear body intended to be connected to the front body, as well as a device intended to maintain the cable in position relative to the connector so that allow reproducible deformation of the conductor outside during the connection operation, this device intended to hold the cable in position being constituted at least two parts cooperating to maintain and guide the cable in a reproducible manner, including a ferrule intended to hold the cable, and a cooperating socket with the ferrule so as to allow axial displacement over a determined distance from the ferrule and the cable by relative to the socket during the connection operation.

- the ferrule can advantageously be provided with a longitudinal slot allowing a clamping of the diameter of the ferrule, and an internal thread or profile allowing to hang the smooth outer conductor during the clamping of the ferrule.
- the ferrule is preferably provided, on the side of the socket, with a cone outside and inside, and the socket with a cone at the inlet and in the bottom, the cone outside of the ferrule being intended to cooperate with the cone at the inlet, the socket to cause the tightening of the slotted ferrule, and the cone of the bottom of the socket being intended to cause the determined deformation of the external conductor, in cooperation with the cone inside of the ferrule.
- the parts cooperating to hold and guide the cable in a reproducible manner may usefully further comprise a ring intended to advance the ferrule during assembly of the rear body of the connector, making it possible to wedge the ferrule between the socket. and the ring.

- the cable is a coaxial cable with conductor spiral exterior (10).
- the ferrule (1) is provided with the inside of a special thread (12) which allows you to screw inside the outer conductor of the cable and has a geometry which prevents its rotation around its axis while keeping the possibility of axial displacement which can in this case be an area with two dishes which matches the two socket plates (2).

Description
De manière préférée la déformation du conducteur extérieur est provoquée et déterminée par un plan frontal de ladite douille.
Ce procédé met en oeuvre un nouveau connecteur qui lui aussi fait l'objet de l'invention
Le connecteur selon l'invention peut également de manière avantageuse comprendre un joint d'étanchéité prévu entre le corps arrière et les pieces coopérant pour maintenir et guider le câble.
Dans ce mode de réalisation la ferrule et la douille sont de préférence chacune pourvues de zones avec plats s'épousant mutuellement, empéchant une rotation de la férule et de la douille l'une par rapport à l'autre, et de gorges destinées à y loger une bague permettant le déplacement de la ferrule par rapport à la douille avec une course déterminée.
Dans ce mode de réalisation les pièces coopérant pour maintenir et guider le câble d'une manière reproductible, peuvent utilement en outre comprendre une bague destinée à faire avancer la ferrule lors du montage du corps arrière du connecteur, permettant de coincer la ferrule entre la douille et la bague.
- la figure 1 représente une vue en perspective des pièces de maintien (ferrule et douille, montrées séparées) d'un connecteur selon un premier mode de réalisation de l'invention (connecteur pour câbles à conducteur extérieur spiralé) ;
- la figure 2 représente une vue en perspective des pièces de la figure 1, montrées assemblées;
- la figure 3 représente une vue en élévation, partiellement en coupe, d'un connecteur selon l'invention utilisant les pièces de maintien des figures 1 et 2;
- la figure 4 représente une vue correspondant à la figure 3, montrant le connecteur avec un câble coaxial, avant l'opération de déformation du conducteur extérieur;
- la figure 5 représente une vue correspondant à la figure 4, après l'opération de déformation du conducteur extérieur;
- la figure 6 représente une vue en perspective des pièces de maintien (ferrule et douille, montrées séparées) d'un connecteur selon un deuxième mode de réalisation de l'invention (connecteur pour câbles à conducteur extérieur lisse) ;
- les figures 7 à 9 représentent des vues en coupe d'un connecteur selon l'invention utilisant les pièces de maintien de la figure 6, disposé sur un câble coaxial, montrés à des phases successives de l'opération de capture et de déformation du conducteur extérieur.
Dans la figure 5, on voit qu'en vissant l'arrière (8) celui-ci fait avancer la ferrule (1) et comprime le joint (7) qui se moule autour du conducteur extérieur et de la gaine du câble. Dans un second temps, l'arrière (8) arrive à toucher et pousser la ferrule (1) qui avance vers la douille (2) en déformant le conducteur extérieur (10) du câble pour assurer un bon contact. Suivant la forme du plan frontal (13) de la douille (2) du côté de la ferrule (1) et de la forme de celle-ci, le conducteur extérieur du câble peut être comprimé ou évasé. Dans le mode de réalisation représenté, le conducteur extérieur (10) est déformé contre le plan frontal (13) de la douille (2), tandis que le diélectrique (16) qui se trouve entre le conducteur extérieur (10) et le conducteur central (14) pénètre dans la douille (2); le conducteur (10) subit une déformation finale (17) illustrée à la figure 5. Comme la déformation du conducteur extérieur du câble, déterminée par la longueur (L), est rigoureusement reproductible, on crée un défaut d'impédance reproductible qui peut être compensé électriquement par le bon dimensionnement du connecteur.
La douille (2) est pourvue d'un cône (c) à l'entrée et d'un cône (d) dans le fond.
Derrière la bague (20), il y a le joint torique (27) et l'arrière (8) qui est pourvu du joint torique (9) dans la gorge du filet.
