In contrast, the use of electricity by An Wang is also something that modern people cannot care about. Generally speaking, in the overall circuit circuit that supplies electricity, there is a power supply control 22 = the main switch is energized (0N), the fuse is set or broken L, and the electrical appliances used in the circuit circuit are too much to cause current = The circuit is over the «form, the protection (four) is based on the electricity (four) off (four) and the open circuit (0FF) state of the circuit.乂成正肢 additionally 'in the whole circuit loop, there are separate switches in the respective circuit. 'The switch is mainly:, = power-on _ and power-off clerk) two kinds of actuation strokes, for reinforcement:::= Sexuality, many switches also have a current overload and overheat when the automatic jump: power? Avoid the fuse of the whole circuit loop or the disconnection of the whole circuit loop during the current overload to cause power failure or tripping, and the risk of wire fire occurs. In the case of power failure, the whole circuit loop and the individual circuit loops are used, and the companion-electronics, the uploading overheating automatic tripping, and the power-off structure are used, and the eight-in-one products are used, such as high-priced electronic products. , Lu Tian knife equipment or electricity consumption to teach higher electric appliances, etc. 'wide data of the information electrical circuit with the tank ^ /,, do not set the temperature sensing broken child road edge protection structure, straw to protect the single electron early An electronic, emperor-product mouth, in the smashing +, overload, when the circuit is overheated, immediately save the burning of the product itself, while avoiding the single circuit circuit caused by the single-electron:= problem, Heart ~ ^ "Production of overheating conditions, resulting in current overload of the 1-circuit two-body circuit loop, the problem of the operation of the system. Its U-electric equipment has no one ~ one used in the early-electronic products of the conventional temperature-sensing power-off protector, such as The piece (10) is set to -me:,,, τ contact elastic piece (201), the contact elastic piece bow is deformed after the fork heat and bucks in the opposite direction, the contact end is fixedly set at the first terminal (10), and the contact elastic piece (10) Another thin horse free end, since The end group is provided with a first fixed group h point _), and the second second terminal (204) port has another V electric point (2〇5), and the second conductive point (2〇5) corresponds to the first conductive, one () 'Besch, the contact spring piece (2〇1) is bent in the direction of the second terminal (2〇4) so that the first conductive point (203) and the second terminal (-4) of the free end of the contact spring piece (2〇1) are contacted. The _ conductive point (2 () 5) maintains the circuit connection state of the contact, as shown in the first figure 2, when the current is overloaded, the contact spring piece (201) is thermally deformed and bucked in the opposite direction to bounce, so that the contact spring piece (2 〇 1) The first conductive point of the free end (2 is separated from the second conductive point (205)' into a circuit cut-off (〇ff) state, as shown in the second figure, to ensure that the electronic product itself is protected from burning.
