Backpack power-off reset temperature limiter

A backpack power-off reset temperature limiter, comprising:

• an insulating base (1),
• a first terminal (11),
• a second terminal (12),
• a power-receiving elastic piece (2), and
• an arch-shaped temperature sensing sheet (3), wherein the first terminal (11) and the second terminal (12) are respectively connected to two ends of the insulating base (1) in an injection molding mode, and the power-receiving elastic piece (2) is arranged on an upper end surface of the insulating base (1), wherein one end of the power-receiving elastic piece (2) is fixedly connected with the first terminal (11), and an other free end of the power-receiving elastic piece (2) are electrically connected with the second terminal (12), wherein the temperature sensing sheet (3) is arranged on an upper surface of the power-receiving elastic piece (2), wherein two ends of the power-receiving elastic piece (2) are respectively provided with a fixing clamping position (21) that is clamped with an end part of the temperature sensing sheet (3), and two sides of the power-receiving elastic piece (2) are respectively provided with an assembly clamping position that is matched with the temperature sensing sheet (3), wherein the two ends of the insulating base (1) are respectively provided with an injection molding hole (10), wherein a first folding plate (111) is arranged on the first terminal (11), and a second folding plate (121) is arranged on the second terminal (12), wherein the first folding plate (111) and the second folding plate (121) are respectively inserted into the corresponding injection molding hole (10), and the first terminal (11), the second terminal (12) and the insulating base (1) are connected into an integral structure by means of injection molding, wherein an upper end surfaces of the first folding plate (111) and the second folding plate (121) are exposed on the upper end surface of the insulating base (1), and vertical through-holes (100) are formed in the first folding plate (111) and the second folding plate (121), wherein the assembly clamping position comprises limiting lug pieces (22) and introducing lug pieces (23), wherein at least two limiting lug pieces (22) are arranged on one side of the power-receiving elastic piece (2), and at least two introducing lug pieces (23) are arranged on the other side of the power-receiving elastic piece (2), wherein an included angle between the introducing lug piece (23) and the power-receiving elastic piece (2) is larger than 120 degrees.
