The present invention relates to a method of coating the junction area between elongated elements, in particular between electric cables. This method comprises the steps of: arranging a rigid tubular support (10) having two axially separable tubular halves (11,12); mounting an elastic tubular sleeve(20) in an elastically radially expanded condition on an outer surface of the support (10); interposing a lubricating material (30) between the support (10) and sleeve (20); arranging a circumferentially continuous sealing element (40) between the halves (11,12) to prevent the lubricant from percolating between said halves; positioning the support (10) around the junction area and moving the halves (11,12) apart from each other to enable the sleeve (20) to collapse on the junction area. Further described is a device for coating the junction area between elongated elements, a method of making said device and a joint for electric cables.
La présente invention porte sur un procédé permettant de recouvrir la zone de raccord entre des éléments allongés, en particulier entre des câbles électriques. Ce procédé comprend les étapes consistant à: à utiliser un support tubulaire rigide (10) comportant deux moitiés tubulaires axialement séparables (11, 12); à monter un manchon tubulaire élastique (20) dans un état radialement et élastiquement déployé sur une surface extérieure du support (10); à intercaler un matériau lubrifiant (30) entre le support (10) et le manchon (20); à disposer un élément d'étanchéité continu sur toute la circonférence (40) entre les moitiés (11, 12) pour empêcher le lubrifiant de s'infiltrer entre ces moitiés; à positionner le support (10) autour de la zone de raccord et à éloigner les moitiés (11, 12) l'une de l'autre afin de permettre au manchon (20) de s'écraser sur la zone de raccord. Cette invention concerne également un dispositif permettant de recouvrir la zone de raccord entre des éléments allongés, un procédé de production de ce dispositif, ainsi qu'un joint pour câbles électriques.
