Secondly, when the temperature detector is assembled, the metal mesh layer A3 is firstly shrunk or expanded, so that the conductive terminal D is riveted and covers the metal lead B1 of the detector B and the lead body A1 of the coaxial cable A, an insulating sleeve E is sleeved on the conductive terminal D, then the metal mesh layer A3 is restored, and finally the tail end of the metal mesh layer A3 is bundled by the copper terminal B2 and the metal lead B1, so that the metal mesh layer A is combined with the metal shell C, the assembling process is complex, and the labor cost is increased.
