A screen connector (10) for electrical cables and/or for jointing assemblies for electrical cables is disclosed. In high voltage electrical cables one or more conductors are covered by an insulating layer with a conductive screen coaxial over the insulation. In prior art jointing assemblies metallic shield sock surrounds a splice body held in a radially expanded state by a support core. The shield sock can be put in electrical contact with a metallic shield of the cable by the use of one or more mechanic clamps, which may be a constant force spring. Using mechanic clamps of the aforementioned type causes an increase of the time and complexity of the splicing operation. To reduce the time and complexity of the splicing operation the following connector is proposed. The connector has a conductive shield sock (11) extending about a longitudinal axis (X-X) and adapted to be coupled to a conductive screen of at least one electrical cable or to at least one jointing assembly for electrical cables. When used a part of a cable connection a shrinkable protective sleeve (12) is arranged in a radially outer position with respect to the conductive shield sock (11). At least one removable support element (13) is arranged in a radially inner position with respect to the conductive shield sock (11) to hold the conductive shield sock (11) and the shrinkable protective sleeve (12) in a radially expanded state so that a cable may be slipped inside. A jointing assembly for electrical cables is also disclosed, the jointing assembly being either in a radially expanded state or radially collapsed onto an end portion of at least one electrical cable. The jointing assembly is either a joint for connecting two electrical cables or a termination for connecting one electrical cable to a different device. |
