| 摘要 | PURPOSE: To prevent a dangerous state caused by an over-heating from being applied by a method wherein two planar connection pieces are arranged in a spring contact, and a thermal melting conductive packing comprised of a low malting point metallic part and an insulating elastomer which can electrically connect both pieces is arranged between the two pieces. CONSTITUTION: A spring contact in an electric cigar lighter in which an electric circuit is formed when a heater element is inserted into a spring contact so as to generate heat is provided with a main body having a bi-metal 1 and a bolt 2, an insulating member 3, two planar connecting pieces 4 and 4', a washer 6 and a nut 7. A temperature melting conductive packing 10 comprised of a low melting point metallic part A capable of electrically connecting both pieces 4 and 4' and an insulating erastomer B is inserted between the planar connecting pieces 4 and 4'. As material of the low melting point metallic part A forming the temperature melting conductive packing, metal or alloy having melting point lower than 430°C is preferable and as material for the insulating erastomer B, erastomer of solid type is preferable in view of the fact that it has a resiliency as a packing.
