Description of the invention: [Technical field of the invention] The present invention relates to a circuit protector for double temperature induction power-off, which is provided with a contact spring piece and a thermal fusion breaking device in the circuit circuit to form two independent Operational temperature-sensing power-off device; when the current is overloaded, the circuit is overheated, or the ambient temperature used is too high, the contact spring is heated and deformed by reverse bending, or the soluble alloy of the hot-melt breaking device is melted to make the thermal solution open. The device trips into a circuit open (OFF) state. [Prior Art] _ The use of electricity has become an indispensable part of modern human society. The use of electric power equipment surrounds the periphery of life, especially computerized, informationized industries, home, transportation, education, entertainment, etc. No electricity can be achieved. The use of electricity and its equipment has created a convenient modern life. Relatively, the safe use of electricity is also something that modern people cannot care about. Generally, a power-controlled main switch is provided in an overall circuit circuit that supplies electricity. Usually, the main switch is in an energized (ON) state, and a fuse or a breaker is placed thereon, and an electric current is excessively generated when an electric circuit is used in the circuit circuit. In the event of an overload, or short circuit, > overheating of the circuit, the fuse blows or the breaker breaks out to form an open circuit (OFF) state of the overall circuit loop. In addition, there are separate circuit loops in the whole circuit loop, and a control switch is further provided in the circuit loop, and the switch mainly performs two kinds of actuation strokes of energization (ON) and power-off (OFF) of the respective current loops. In order to enhance the safety of power consumption, many switches also have the function of automatically tripping and power-off when the current is overloaded and overheated, so as to avoid the fuse or the breaker of the whole circuit loop cannot react immediately to perform power-off or trip when the current is overloaded. And the danger of wire fires. 5 .1275224 In addition to the above-mentioned integral circuit loop and individual circuit loops, the current overload and overheating of fuses, breakers and switches are automatically tripped and the power-off structure is used. Some single electronic and electrical products, such as high-priced electronic products, The information equipment for processing data or the electric heating device for teaching electricity, and the circuit protection structure of the temperature sensing breaker are respectively provided to protect the single electronic and electrical products in the single electronic and electrical products themselves. When the current is overloaded and the circuit is overheated, the power is instantaneously sensed and the power is cut off, so as to avoid burning the product itself, and at the same time, the current overload and overheat condition of the respective circuit loop and the whole circuit loop caused by the problem of single electronic and electrical products can be avoided. The problem that the circuit loop and other electrical equipment in the overall circuit loop cannot operate. 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 spring piece (201) in the circuit, and the contact spring piece (201) is curved, after being heated Deformed and bucked in the opposite direction, the 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 second terminal (204) is fixedly disposed with a second conductive point (205), and the second conductive point (205) corresponds to the first conductive point (203); when implemented, the contact spring (201) is oriented to the second terminal (204) Bending, the state in which the first conductive point (203) 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 elastic piece (201) is thermally deformed and bucked in the opposite direction to bounce, so that the first conductive point (203) of the free end of the contact elastic piece (201) is separated from the second conductive point (205), and the circuit is turned off (OFF). As shown in the second figure, the circuit of the electronic product itself can be protected from burning.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 reaction temperature value of the elastic piece (201) deformed after being heated and reversely bounced, and the temperature value of the 6 1275224 fixed induction is large. (b) The contact shrapnel (201) is deformed after being heated and has a sharp abrupt bounce. 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 the state of current conduction, and the circuit continues to overheat, posing a danger to the electronic product and the entire circuit. When the current overload circuit is overheated, if the contact spring piece (201) is in the half-trip state, when the contact spring piece (201) cools, it will jump back to the power-on state, and the power supply will continue to be repeatedly turned off, the power is cut off, and the spark is generated, causing danger; and the overall current The electronic and electrical equipment in the circuit is unstable due to repeated power-on and power-off, which may cause the machine to malfunction or not, and shorten the service life or even complete damage. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to solve the problem that the conventional temperature-sensing power-off protector has only one tripping and power-off device that is inductively contacted by the contact spring, and cannot effectively set the sensing temperature of the power-off value. And, when the current overload is overheated, if the contact spring cannot be instantaneously jumped, the jump is incomplete, or the trip cannot be tripped, the circuit continues to conduct, the circuit generates sparks or repeatedly energizes, and the power is turned off, causing the current to be unstable, causing the electronic product to crash. Or problems that cannot function properly, shorten the service life, or even completely damage. Technical Solution for Solving the Problem: The present invention is a double temperature-sensing power-off circuit protector, which is provided with a contact spring piece and a thermal fusion breaking device between two contact terminals of the circuit circuit, wherein, 7.1275224 the thermal fusion circuit The device is provided with a connecting member and a fusible alloy; when the current overload, the circuit is overheated or the ambient temperature used is too high, the contact elastic piece is heated and deformed and reversely bent to jump off, forming a first type of circuit breaking state, and the other is When the current overload, the circuit is overheated or the ambient temperature used is too high, and the aforementioned contact elastic piece fails to be instantaneously or cannot be deformed, the reverse circuit bends off and the power is turned off, the temperature of the circuit loop continues to rise, and the fusible alloy of the thermal fusion breaking device The temperature rises and melts and breaks, causing the connector to trip, forming a second circuit open state, and using two independent temperature-sensing power-off devices to ensure that the circuit loop is completely turned off (OFF). The invention has a double temperature-sensing power-off circuit protector, and its main purpose is to independently sense the temperature when the current is overloaded or the circuit is overheated by two independent temperature-sensing breaking devices. The circuit loop is completely de-energized (OFF), with dual temperature-sensing disconnection to ensure the safety of electricity. Another object of the present invention is that when the current is overloaded and the circuit is overheated, in general, the contact spring is thermally deformed and reversely tripped, so that the circuit circuit is powered off (OFF) without using the fusible device to be fusible. The alloy breaks to achieve the circuit loop power-off (OFF); after the circuit loop overload factor is removed, the contact spring can be returned to the energized (ON) state, the circuit protector can still be used repeatedly, easy to use, and the new circuit is not installed. Protector saves time and reduces user expenses. A further object of the present invention is that when the current is overloaded and the circuit is overheated, the contact spring cannot be instantaneously tripped, half-tripped, unable to trip or contact the shrapnel to cool back to the ON state, and then further thermally disconnected. The easy and molten alloy of the device will continue to heat up and will melt and break, so that the circuit circuit is completely disconnected (OFF), ensuring safe use of electricity, and protecting the electrical characteristics of various electrical appliances in the circuit circuit.
