Abstract: The present invention relates to a plug and a socket, which are each designed to be capable of being connected to a coded thermal line protected against polarity reversal. To this end the plug and the socket each comprise a recess which is configured to receive, in a manner protection against polarity reversal, a thermal line with an asymmetrically designed cross section and a first and a second electrically conductive plug or socket element which each comprise a first and a second area. The first area of the plug and socket elements each comprise a spring contact, and the plug and socket elements are arranged in such a manner that the two spring contacts each contact substantially axially a core of a received thermal line.

Abstract: The present invention relates to a thermal line (1) for transmitting an electrical signal to a module block (5) comprising a group of connections for electrical contact to be made by the thermal line (1), and to a system of module blocks. The thermal line (1) comprises a first core (2a) and a second core (3a), a first core insulation material (2b) and a second core insulation material (3b) and also an external insulation material (4), wherein the first core (2a) is sheathed at least once by the first core insulation material (2b) and forms a first line element (2), and the second core (3a) is sheathed at least once by the second core insulation material (3b) and/or is separately sheathed at least once by the external insulation material (4) and forms a second line element (3). Furthermore, the first line element (2) has a first outside diameter (D1) and the second line element (3) has a second outside diameter (D2), wherein the first outside diameter (D1) differs from the second outside diameter (D2).
