Embodiment 1
[0026] See figure 1 , the electrical protection device provided with the positive temperature coefficient thermistor device includes: a positive temperature coefficient thermistor 1, the shape of the positive temperature coefficient thermistor 1 is just like the shape of a button described in daily life, Disc body trend. The industry usually refers to positive temperature coefficient thermistor 1 as PTC thermistor (PTC's English name is: Positive Temperature Coefficient), and its main material is ceramic barium titanate (BaTiO 3 ), the main feature is that in the operating temperature range, its resistivity increases with the increase of temperature, and it changes nonlinearly, which is called nonlinear PTC effect in the industry. Depend on figure 1 As shown, one side of the positive temperature coefficient thermistor 1 is formed as a first electrode surface 11 , while the other side is formed as a second electrode surface 12 . at present figure 1 The shown posit...
Embodiment 2
[0032] Not shown in the figure, the criss-cross relationship between the aforementioned first and second elastic sheets 21, 31 can be reversed. More specifically, a pair of first elastic sheets 21 are arranged laterally relative to the first electrode surface 11, However, a pair of second elastic sheets 31 are arranged longitudinally relative to the second electrode surface 12, so that the first and second elastic sheets 21, 31 also form a cross relationship, and can embody the technical effect described in embodiment 1.
Embodiment 3
[0034] Not shown, the distance between a pair of first elastic sheets 21 is preferably equal to the distance between a pair of second elastic sheets 31, but if someone deliberately designs the distance between a pair of first elastic sheets 21 to be greater than or less than one As for the distance between the second elastic pieces 31, it should be regarded as a change in form rather than in substance, and thus still belongs to the protection scope of the solution of the present invention and is limited. In addition, if the pair of first elastic pieces 21 and the pair of second elastic pieces 31 are changed from the eight-shaped shape in the first embodiment to the V-shaped shape, it also belongs to the protection scope of the solution of the present invention.
