The terminal block (10) serves for electrically connecting a connection line having at least two conductors (L1, L2) and extending externally of an electronics housing (H). The terminal block comprises a platform (100) composed at least partially of an electrically insulating, synthetic material, especially a synthetic material having a dielectric strength sufficient to meet European standard EN 60947-1, a connection terminal (TI) arranged on a first side of the platform forming a first connection side of the terminal block and serving for connection of a conductor (L1) of the connection line as well as at least one connection terminal (T2) arranged on the first side of the platform, laterally spaced from the connection terminal (T1) for connection of a conductor (L2) of the connection line. Additionally, the terminal block comprises a connection contactor (J1) arranged on a second side of the platform forming a second connection side of the terminal block, e.g. especially a connection contactor embodied as a contact pin or as a contact jack, as well as a connection contactor (J2) arranged on the second side of the platform and laterally spaced from the connection contactor (J1), e.g. a connection contactor embodied as a contact pin or as a contact jack.
