Abstract

An apparatus for electrically connecting at least four electrical conductors includes a connecting element and at least four shielding pipes, which are each provided for receiving at least one conductor. In order to enable a simple and economical connection, the connecting element forms pipe connection pieces and each connection piece is integrally joined or materially bonded to a respective shielding pipe.

First claim

1 - 12 . (canceled)

13 . An apparatus for electrically connecting at least four electrical conductors, the apparatus comprising:
at least four shielding pipes each configured to receive at least one of the conductors; and a connecting element forming pipe connection pieces, each of said pipe connection pieces being connected to a respective one of said shielding pipes by a material-bonded connection.

14 . The apparatus according to claim 13 , wherein said connecting element and each of said shielding pipes are formed of an electrically conductive material.

15 . The apparatus according to claim 13 , which further comprises a paper insulation surrounding said connecting element, said pipe connection pieces and said shielding pipes.

16 . The apparatus according to claim 13 , wherein each of said pipe connection pieces is soldered or welded to a respective one of said shielding pipes.

17 . The apparatus according to claim 13 , which further comprises a barrier system made of pressboard, said shielding pipes and said connecting element being surrounded by said barrier system.

18 . The apparatus according to claim 17 , which further comprises a housing of a transformer or an inductor, said connecting element and said shielding pipes being disposed in an oil bath inside said housing.

19 . The apparatus according to claim 18 , wherein said transformer or said inductor has windings, and at least one of the conductors is electrically conductively connected a respective one of said windings.

20 . The apparatus according to claim 13 , wherein said pipe connection pieces have at least one of different structures or different diameters.

21 . The apparatus according to claim 13 , wherein said pipe connection pieces and said shielding pipes respectfully connected to said pipe connection pieces have different diameters from one another.

22 . The apparatus according to claim 13 , wherein at least one of said pipe connection pieces and said shielding pipe connected thereto form a contact point and span an angle (alpha) of less than 180 degrees with one another with respect to said contact point.

23 . A transformer, comprising an apparatus according to claim 13 .

24 . An inductor, comprising an apparatus according to claim 13 .
