The utility model belongs to the technical field of temperature sensors, and particularly relates to a structure for relieving thermal expansion and cold contraction stress. Comprising a cable, a core wire and a thermosensitive element, the cable comprises the core wire, the core wire extends out of the cable, and the extending part of the core wire is fixedly connected with the thermosensitive element; and the length of the extending part of the core wire is greater than the linear distance between the end part of the cable and the thermosensitive element. By lengthening the extension length of the core wire and additionally arranging the S-shaped bend on the core wire, stress generated by circulation at the high temperature of 900 DEG C to the room temperature can be effectively eliminated, welding spots and leads are effectively protected, and the service life of a product is effectively guaranteed. 本实用新型属于温度传感器技术领域，具体涉及一种减缓热胀冷缩应力的结构。包括电缆、芯线、热敏元件；所述电缆包括所述芯线，所述芯线伸出所述电缆，所述芯线的伸出部分与所述热敏元件固定连接；所述芯线的伸出部分长度大于所述电缆
