Abstract
The utility model belongs to an over-voltage protector used for lightning protection protectors for computers and various domestic appliances. Two pressure-sensitive resistors are arranged in the casing of a power socket. The A poles of the two pressure-sensitive resistors are connected together and are connected with an earth terminal and a ground wire. The B poles of the two pressure-sensitive resistors are respectively connected with two terminals of a power cord and two power cords. The utility model has the advantage of safe and convenient use. If only a power plug is directly inserted into the socket of the over-voltage protector, the damage resulted from lightning for computers and various domestic appliances can be effectively prevented. The pressure-sensitive resistor elements are sealed in an insulation model in the over-voltage protector. The service life and the circuital safety are ensured.
Description
The utility model belongs to a kind of overvoltage protection device, refers in particular to the anti-lightning strike protector that is used for computer and various household electrical appliance.
In known prior art, the lightning arrester of household electrical appliance all is an independent device, needs the user to be installed in voluntarily in the power circuit that is connected during use, so extremely inconvenience and don't safety.
The purpose of this utility model provides a kind of lightning arrester of novelty, and with anti-lightning strike major function element, Zinc-oxide piezoresistor directly is assembled in the supply socket, is combined as a whole, and the user does not need just to install separately and can directly use.
Technical application scheme of the present utility model is that two piezo-resistances are installed in the supply socket housing, the A utmost point of these two piezo-resistances links together, be connected with earth connection with earth connection point, the B utmost point of two piezo-resistances is connected with two power lines with two power cord connectors respectively.
The utility model has the advantages that: safe and convenient to use, only need the attaching plug of computer or household electrical appliance is directly inserted the socket of this protector, just can prevent the infringement that computer and various household electrical appliance cause when avoiding being subjected to being struck by lightning effectively.Because the piezoresistive element insulation is closed in this protector, has guaranteed the safe and reliable of useful life and circuit.
Description of drawings of the present utility model is as follows:
Fig. 1 is the configuration state schematic diagram of the utility model embodiment.
Fig. 2 is the circuit connection diagram of the utility model embodiment 1.
Fig. 3 is the circuit connection diagram of the utility model embodiment 2.
Number in the figure is described as follows:
