Auxiliary connection for terminal blocks

摘要

The auxiliary connection (1) has an insulator housing (2), in which a connector (6) for realizing a line connection is arranged. The connector is connected with a screw and socket arrangement (8), which has a screw (9) and a socket (12) that is designed for contacting an opening of a terminal block and for conductively contacting a bus bar and/or an interconnection unit of the terminal block . The socket is designed in an exchangeable manner, so that an additional connection is formed by exchange of the socket for contacting the socket with the interconnection unit. An independent claim is also included for a system of auxiliary connections.
