Embodiment
See also Fig. 1 to shown in Figure 3, the utility model thermistor comprises: a thermistor body 10, two electrode pins 20, a metal stator 30, an and cladding 40.
This two electrodes pin 20 is arranged at an end of this thermistor body 10, and realizes electrically connecting with this thermistor body 10, and this two electrodes pin 20 has different polarity, and its length can be identically, or one is long and the other is short.The jack (figure do not show) of this two electrodes pin 20 in order to be inserted in a printed circuit board (PCB), and realize electrically connecting with this printed circuit board (PCB).
This metal stator 30 is arranged at a side of this thermistor body 10, this metal stator 30 has a joint portion 31, reaches a weld part 32, wherein the shape of this joint portion 31 is roughly corresponding to this thermistor body 10, and this joint portion 31 is connected to a side of this thermistor body 10.And the width of this weld part 32 is narrow than this joint portion 31, but does not limit, and this weld part 32 is positioned at the other end of these thermistor body 10 relative these two electrodes pins 20 and stretches out outside this thermistor body 10.In other words, this weld part 32 and this two electrodes pin 20 lay respectively at the opposite end of this thermistor body 10.In addition, the material of above-mentioned metal stator 30 does not have qualification, and the preferably makes with tinplate.
