Description of the Invention: [Technical Field] The present invention relates to a micro-miniature breaker that is connected to a circuit by a two-terminal connection in a contact elastic piece, and the contact elastic piece is fixed and bent at one end. The elastic bending section is extended to reduce the space length of the contact elastic piece by the arrangement of the elastic curved section, thereby effectively reducing the size of the contact elastic piece and achieving the purpose of miniaturizing the electrical breaker. [Prior Art] In general, the whole circuit circuit and the separate switch circuit circuits of the power supply use fuses, breakers, overheating, automatic tripping, etc. to protect the circuit from overheating due to current overload. Wires are off fire to ensure safe use of electricity. In some single electronic and electrical products, such as high-priced electronic products, information processing equipment for processing data, or electric heating devices with high electricity consumption, circuit protection of temperature-sensing breakers is also provided inside the power cord or the body. The structure is used to protect the single electronic and electrical products, so that the single electronic and electrical products themselves are inductively powered off when the current is overloaded and the circuit is overheated, so as to avoid burning the product itself, and at the same time avoiding the single electronic and electrical products. The problem is that the current circuit overload or overheat condition of the respective circuit loop or the whole circuit loop causes the problem that the individual circuit loops or other electrical equipment in the overall circuit loop cannot operate. The conventional temperature-sensing power-off protector used in a single electronic product is connected to a two-terminal communication circuit by a contact elastic piece, and is characterized in that the contact elastic piece is deformed by heat and reversely bends and bounces to break the circuit circuit, although When the current overload is overheated, it automatically trips and powers off; however, the disadvantages of these conventional temperature-sensing power-off protectors are: (a) The contact spring of the conventional temperature-sensing power-off protector is curved and has a heat of U/4469. The characteristics of deformation and reverse bending and bounce; whether it is stamping or assembling into a curved arc in contact with the elastic piece, it is difficult to ensure effective control of the contact elastic piece due to the fact that the thickness and bending characteristics and structural characteristics of each contact elastic piece cannot be ensured at the same time. The value of the reaction temperature after deformation and buckling in the reverse direction is large, and the value of the induction temperature is set to be large, and the quality control is not easy. (b) The arc-shaped contact elastic piece of the conventional temperature-sensing power-off protector is not sensitive to the deformation and reverse bending of the bounce after being heated, and the protection of the electronic product in the event of overload and overheating cannot be performed in time. (4) Since the space length and size of the contact spring are not reduced, the size and total volume of the conventional temperature-sensing power-off protector are relatively large, and the size of the power-off protector cannot be miniaturized. The large-size 'large-sized power-off protector is placed on the power line to visualize the appearance of the product, and the inside of the electric appliance increases the volume of the electrical product. ° (d) It is not possible to reduce materials or reduce product manufacturing costs. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to solve the disadvantages of the arc-shaped contact elastic piece of the conventional temperature-sensing power-off protector, such as the inability to effectively control the reaction temperature of the contact elastic piece and the reverse bending bounce. The value 'sets the value of the sensing temperature is large, the quality control is not easy', the acuity is not high, and it is impossible to jump off and power off in case of overload and overheating to keep the electronic product 'unable to reduce the length and size of the contact bomb (4). The size and total volume of the induction power-off protection are relatively large, and it is impossible to reduce the material and low production cost. Technical means to solve the problem. 1374469 * · The sheet has an elastic recovery force of the outer sheet, and the overall structure is simple and easy to manufacture. The requirements for volume miniaturization can be achieved, and the component materials are reduced, and the manufacturing cost is effectively reduced.
