A conventional temperature-sensing power-off protector for use in a single electronic product, as shown in the first to second figures, is provided with a contact elastic piece (201) in the circuit, and the contact elastic piece (2〇1) is set to be curved, After being heated, the deformation is reversed and bent to bounce. One end of the contact elastic piece is fixedly disposed on the first terminal (202), the other end of the contact elastic piece (201) is a free end, and the free end is provided with a first conductive point (203), and the other end is provided with a first conductive point (203). A second conductive point (205) is fixedly disposed on the second terminal (2〇4), and the second conductive point (2〇5) corresponds to the first conductive point (2〇3); the implementation day ττ 'contact elastic piece (201) Bending in the direction of the second terminal (204) to maintain a circuit communication state in which the first conductive point (2〇3) contacting the free end of the elastic piece (201) is in contact with the second conductive point (205) of the second terminal (204), As shown in the first figure; when the current is overloaded, the contact spring piece (201) is thermally deformed and the 1262520 is bent in the opposite direction to be in the megagram, so that the first conductive point (203) and the second conductive point contacting the free end of the elastic piece (201) are contacted. (205) Separate, the state of the circuit is turned off (OFF), as shown in the second figure, to ensure the electronic product itself The circuit is protected from burnout. However, the disadvantages of the conventional temperature-sensing power-off protector are: (a) When making the contact spring piece (201), it is impossible to ensure that the thickness, curvature and structural characteristics of each piece of contact spring piece (201) are completely the same, so it is difficult to effectively control the contact. The value of the reaction temperature of the elastic piece (201) deformed after being heated and reversely bounced, and the error of the temperature value of the induction is set to be large. (b) The contact shrapnel (201) is deformed after being heated and the sensitivity of the reverse bounce is not south. The protection of the electronic product during overload and overheating cannot be performed in time. (c) The contact spring (201) cannot be instantaneously tripped or the trip is incomplete, so that the circuit is still in a current conducting state, and the circuit continues to overheat, posing a danger to the electronic product and the overall circuit. When the current overload circuit is overheated, if the contact spring piece (201) is in the half-bounce state, when the contact spring piece (201) cools, it jumps back to the power-on state again, and repeatedly energizes and turns off the power to form a spark, which causes danger; and the overall current loop The electronic and electrical 1§ equipment is unstable due to repeated power-on and power-off, causing the machine to fail or operate normally, reducing the service life and even completely damaging it. SUMMARY OF THE INVENTION The technical problem to be solved by the invention is to solve the shortcomings of the conventional temperature-sensing power-off protector for temperature sensing, in particular, the thickness, the curvature and the structural characteristics of each piece of the contact elastic piece cannot be completely the same, resulting in contact. The reaction temperature of the shrapnel in the case of thermal deformation and reverse bending bounce cannot be effectively controlled. The error of the 1226520 inductive temperature value is set to be large. In the case of current overload and overheating, the contact shrapnel cannot be instantaneously tripped or the trip is incomplete, making the circuit Still in a conducting state, causing overheating of the electronic product and the overall circuit, or causing sparks, causing danger, or repeated energization and power failure, causing current instability, and causing the electronic product to fail to operate normally or shorten the use.

When the current overload or the circuit is overheated and the contact elastic piece fails to be deformed in the reverse direction and is bent and tripped, the power is off. The fusible alloy of the thermal fuse device is melted and fractured by heat to form a complete power-off (OFF) state of the circuit. OBJECT AND TECHNIQUES OF THE INVENTION The present invention is a dual temperature sensing circuit protector whose main purpose is to provide a contact spring and a thermal fuse circuit device between the two contact terminals of the circuit circuit for current overload or circuit. When overheating, the contact elastic piece is heated and deformed and reversely bent to jump off, so that the circuit is in an open state; or when the contact elastic piece fails to deform immediately and reversely bends and trips and is powered off, the fusible alloy of the thermal fusion breaking device is caused by Continued to heat up and melt and fracture, forming a complete power-off (OFF) state of the circuit loop, with dual 1262520 temperature sensing to ensure power-off effect. A further object of the present invention is that when the current is overloaded and the circuit is overheated, the contact elastic piece can react quickly, deform and bend, freely jump, and become an OFF state; when the contact elastic structure is poor, the cooling is jumped back to the power supply. In the state of (ON), the continuous re-energization and power-off form a contact spark phenomenon, which may cause the wire to escape. At this time, the fusible alloy of the hot-melt breaking device of the present invention may be melted and fractured by heating to become a complete circuit breaker. (OFF) state to ensure the safety of electricity.
