Abstract
A system of interconnected heating conductors, suitable for preventing freezing of water lines in an aircraft for example, includes a plurality of heater units (1, 12, 14) electrically coupled together by respective extension cables (3) and electrical coupling elements (42). Each heater unit comprises one or more heating conductor bands, tapes or strips (2, 21, 22) connected to respective connection modules (5, 51, 52, 52', 53) at the ends thereof. The connection modules may connect together several heater bands within one heater unit, and may connect the terminal ends of the heater bands of one heater unit to the extension cables by which several respective heater units may be connected together. Each connection module includes a housing (6) enclosing an inner chamber (61) therein, and at least one electrical connector element (7) such as a crimpable connector fixed within the housing (6). The respective conductors of the heater bands (2) and of the extension cables (3) extend into the housing through lead-in openings (64) and are connected together within the housing (6) by the respective connector elements (7). A complete and reliable seal against moisture penetration is achieve…
