Patent

CA 2213643

A connector system is provided for connecting conductors of high tension cables during splicing between cables. Each connector comprises lugs having ferrule portions which are crimped to the ends of conductors to be joined and part cylindrical lug portions which are bolted together through filler or connector plats to form a smoothly contoured connection free from edges or projections providing high electrical stress concentrations. The connector plates enable two connections to be joined in parallel to provide branch connections: a smoothly contoured lug adaptor replaces a fourth lug if only a single branch connection is to be made. Smoothly contoured and recessed nuts and bolt head covers contribute to the smooth external contour of the connection.

L'invention porte sur un dispositif de connexion servant à connecter des conducteurs de câbles à hautre tension durant des opérations d'épissure entre câbles. Chaque connecteur comporte des cosses munies de portions de ferrures serties sur les extrémités des conducteurs à raccorder et des segments de cosse partiellement cylindriques, boulonnés ensemble à travers une masse de remplissage ou des plaques de raccordement afin de constituer un raccord aux contours adoucis, ne comportant ni rebords ni aspérités susceptibles de provoquer des concentrations de contraintes électriques. Les plaques de raccordement permettent de joindre deux raccords en parallèle de manière à obtenir des raccords en dérivation: un adaptateur de cosse aux contours adoucis ne remplace une quatrième cosse que dans le cas où l'on doit constituer un seul raccord en dérivation. Des couvercles d'écrous et de boulons à tête aux contours adoucis et évidés contribuent à la constitution d'un contour extérieur adouci du raccord.
