  • Patent number: 9853389
    Abstract: A high-voltage cable plug (1) for installing on an end of a high-voltage cable (20) has an insulating part (14) attached to the end of the high-voltage cable (20). The insulating part is cone-shaped at least in some sections on the outer surface of the insulating part and can electrically tight contact a socket element (2) associated with the high-voltage cable plug (1) when the plug-in connection is established. The high-voltage cable plug (1) has a protective element (40) at or near the end of the high-voltage cable plug facing the socket element (2). The protective element protrudes beyond the end of the high-voltage cable plug (1) facing the socket element (2) in a radial direction, with respect to a longitudinal axis (10) of the high-voltage cable plug (1), to such an extent that the protective element (40) prevents damage to the high-voltage cable plug (1) or to the socket element (2) when the high-voltage cable plug (1) is inserted into and removed from the socket element (2).

  • Publication number: 20160352036
    Abstract: A high-voltage cable connector (1) for mounting on one end of a high-voltage cable (20), wherein the high-voltage cable connector (1) has an insulating part (14) that can be mounted on the end of the high-voltage cable (20), which is tapered at least in sections on its outer surface and which can be brought into electrically tight contact with a socket element (2) assigned to the high-voltage cable connector (1) when establishing the plug-in connection, characterized in that the high-voltage cable connector (1) has a protective element (40) on or near its end facing the socket element (2), which protective element protrudes beyond the end of the high-voltage cable connector (1) facing the socket element (2) in a radial direction, relative to its longitudinal axis, to such an extent that the protective element (40) prevents damage to the high-voltage cable connector (1) or to the socket element (2) when the high-voltage cable connector (1) is inserted into and removed from the socket element.
