Plastic sealing internal sheath for a conductor connection, connection part, cover nut and sealed connection between two conductors

Abstract

The invention initially relates to a plastic sealing internal sheath () for a conductor connection between a first conductor () and a second conductor (), wherein, in the connected state, the first conductor () is joined with the second conductor () by means of a mandrel () that yields a conductive connection, wherein the mandrel () passes through a push-through area () of the first conductor (). In order to further improve such a sealing internal sheath, it is proposed that the sealing internal sheath () that can be slipped over the first conductor () exhibits a receiving area () for the first conductor () completely enveloped transverse to a push-through direction (r) at its end allocated to the push-through area () of the first conductor (), and a passage opening () in the push-through direction (r), wherein the passage opening () exhibits a first and second opening edge in the push-through direction (r), and has a closed, continuous sealing lip () at least on the second opening edge, and the end of the sealing internal sheath () facing away from the connection area is designed to interact with the first conductor () so as to form a seal. The invention also relates to a connection part for establishing an electrical connection between two electrical conductors. The invention further relates to a casing for sealing an electrical connection between two electrical conductors.
