Connector for automatically establishing electric connections between vehicles, particularly between railroad vehicles

Claim 1

An improved connector for establishing electric connection between vehicles, particularly between railroad vehicles, comprising two corresponding connection members (1) each of which has a substantially cylindrical shape and is provided with male contact elements (11) and female contact elements (12) secured to it and having a bush (26) with holes (29) therein for housing corresponding male contact elements (11) and slidable axially relative to the corresponding connection member, (1) so as to expose a part of a said male contact elements, (11) each bush (26) being biased axially by a helical spring, (34) wherein the improvement comprises: a. a first flat wall (8) on each bush (26); b. a second flat wall (28) on each bush, (26) slidable relative to a corresponding flat wall (8) of the corresponding connection member (1); c. a cylindrical wall (27) on each bush (26); d. a small block (37) on each said connection members (1), provided with holes (38); e. a plurality of sleeves (42) on each bush (26) each of said sleeves (42) being telescopically engaged in a corresponding hole (38) of said small block and telescopically slidable into it, so as to electrically insulate the corresponding male contact element (11) from the adjacent ones in any operating position of the connector; and f. parts (33) projecting radially from said cylindrical wall portion (27) adapted to abut with a corresponding lip (32) of said connection member (1) for arresting the sliding of the bush (26).
