[0002] In lightning-prone areas, electrical appliances are often struck by lightning. Although lightning protection facilities are installed on the roof, the lightning encountered by many electrical appliances does not come from the roof, but from external power lines or some TV signal lines. Power lines or TV signal lines are set in open areas or high places, which are very vulnerable to electric shocks. This kind of strong current will enter the electrical appliances along the lines, which may easily cause damage to the electrical appliances.
Therefore, when there is a lightning strike, it is generally necessary to unplug the power supply and TV signal line of the TV. Frequent plugging and unplugging will not only bring unnecessary trouble to the user, but also the reliability of lightning protection is not high.
Generally, the lightning protection plug is disposable, and it cannot be used again after a lightning protection, which causes a great waste

The invention creates and provides a lightning prevention plug capable of being repeatedly used for an electrical device. The lightning prevention plug comprises a shell and a lightning prevention protection circuit, wherein the lightning prevention protection circuit is arranged in the shell and also comprises a piezoresistor and an elastic sheet which are sequentially connected in series onto a fire line of an external power supply, one end of the piezoresistor is connected with one end of the elastic sheet by a tin soldering block, the other end of the elastic sheet is fixed on the inner side surface of the shell, the elastic sheet is arranged below the piezoresistor, one end of the elastic sheet is connected with a rotary shaft, the rotary shaft is connected with a handle, and a tin soldering block feeding outlet is arranged at one side of a jack on the shell. The lightning prevention plug capable of being repeatedly used for the electrical device, created by the invention, has the advantages of simplicity in structure, accurate action and working reliability, and can be widely used in various electrical devices requiring overheat protection and lightning prevention protection, such as outdoor instruments and household appliances, the lightning plug can be used, the cost is saved, and energy sources are saved.
Description
technical field [0001] The invention belongs to the technical field of lightning protection equipment, and in particular relates to a lightning protection plug that can be used multiple times. Background technique [0002] In lightning-prone areas, electrical appliances are often struck by lightning. Although lightning protection facilities are installed on the roof, the lightning encountered by many electrical appliances does not come from the roof, but from external power lines or some TV signal lines. Power lines or TV signal lines are set in open areas or high places, and are very vulnerable to electric shocks. This kind of strong current will enter the electrical appliances along the lines, which may easily cause damage to the electrical appliances. Therefore, when there is a lightning strike, it is generally necessary to unplug the power supply and TV signal line of the TV. Frequent plugging and unplugging will not only bring unnecessary trouble to the user, but also t...
