Description
Technical field
The utility model relates to a kind of socket, more particularly, relates in particular to a kind of anti-thunderbolt supply socket.
Background technology
Supply socket is present requisite electric equipment, comprises that socket, wall insert etc., is widely used in various electricity consumptions place.Present electric outlet structure on the market is similar basically, is made up of housing, conducting strip and circuit board, indicator light etc. usually.
As everyone knows, thunderbolt is one of maximum unsafe factor of various electrical equipment, and the high voltage that thunderbolt is produced can damage or burn electrical equipment, even initiation fire.For this reason, the electrical equipment manufacturer usually can be at electrical equipment set inside protective device, like protective tube etc., but limited for the protection effect of thunderbolt.If safeguard procedures can be set in supply socket one, hazards to be eliminated in the electrical equipment part, this must improve the safeguard protection effect of electrical equipment greatly.
The utility model content
The purpose of the utility model is the deficiency to above-mentioned prior art, and a kind of simple in structure, anti-thunderbolt supply socket that lightning protection effect is good is provided.
The technical scheme of the utility model is achieved in that a kind of anti-thunderbolt supply socket; Comprise housing; The power access end of said housing is electrically connected with external power source; On housing, be provided with conducting strip, be provided with anti-thunderbolt module in the wherein said housing, this anti-thunderbolt module is arranged on the circuit between power access end and the conducting strip; Should anti-ly be struck by lightning module by the fuse that is connected electrically on the live wire; Two thermistors that are connected electrically in respectively on zero line, the live wire; At least two at least two second surge protecters that are connected in parallel on first surge protecter between zero line, the live wire respectively and are connected electrically on the circuit of first surge protecter back constitute, and each second surge protecter is connected electrically in respectively between zero line and ground wire and live wire and the ground wire.
In the above-mentioned anti-thunderbolt supply socket, described first surge protecter has two, and two first surge protecters are connected in parallel on respectively between the zero line, live wire on thermistor both sides.
In the above-mentioned anti-thunderbolt supply socket, described second surge protecter has two, and two second surge protecters are connected electrically in respectively between zero line and ground wire and live wire and the ground wire.
After the utility model adopts said structure; Through anti-thunderbolt module is set in housing, through be arranged between live wire and the zero line on the anti-thunderbolt module, surge protecter between zero line and the ground wire, between ground wire and the live wire, in when, thunderbolt taking place producing high voltage; Surge protecter can release out with the voltage that thunderbolt produces step by step; Thereby can the high-voltage variable with very big harmfulness be safe low-voltage, thereby high voltage is cut off on socket, protect the safety of electrical equipment effectively; Further, for the safety of protective circuit, on the live wire on the anti-thunderbolt module, also be connected with fuse, be used for overcurrent protection, it will cut off the power supply when surpassing 15MA automatically; And on zero line and live wire, be respectively equipped with thermistor, it has overvoltage outage and automatically reset function, the operate as normal of assurance device effectively.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to specify, but do not constitute any restriction the utility model.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the electrical block diagram of the anti-thunderbolt of the utility model module.
Among the figure: housing 1, anti-thunderbolt module 2, fuse 3, thermistor 4, first surge protecter 5, second surge protecter 6.
Embodiment
Consult illustrated in figures 1 and 2; A kind of anti-thunderbolt supply socket of the utility model; Comprise housing 1, the power access end of said housing 1 is electrically connected with external power source, on housing 1, is provided with conducting strip; In housing 1, be provided with anti-thunderbolt module 2, this anti-thunderbolt module 2 is arranged on the circuit between power access end and the conducting strip; Should anti-ly be struck by lightning module 2 by the fuse 3 that is connected electrically on the live wire; Two thermistors 4 that are connected electrically in respectively on zero line, the live wire; At least two at least two second surge protecters 6 that are connected in parallel on first surge protecter 5 between zero line, the live wire respectively and are connected electrically on first surge protecter, the 5 back circuit constitute, and each second surge protecter 6 is connected electrically in respectively between zero line and ground wire and live wire and the ground wire; Thermistor 4 in the present embodiment is the NTC thermistor; Simultaneously, first surge protecter 5 in the present embodiment has two, and two first surge protecters 5 are connected in parallel on respectively between the zero line, live wire on thermistor 4 both sides; Second surge protecter 6 in the present embodiment has two simultaneously, and two second surge protecters 6 are connected electrically in respectively between zero line and ground wire and live wire and the ground wire.
During concrete the use; Behind the high voltage entering socket that thunderbolt produces; At first carry out discharge voltage by thermistor 4 first surge protecters 5 in front; Produce high-voltage discharge; And then carry out low-voltage discharge through first surge protecter 5 of thermistor 4 back, flow out by the ground wire discharge respectively by two second surge protecters 6 that are connected electrically in respectively between zero line and ground wire and live wire and the ground wire subsequently; Thereby high voltage is cut off on socket, protect the safety of electrical appliance effectively.
The device of the utility model obtains following result through the surge generator test: the 8KV high voltage is inserted, and behind each surge protecter vent discharge, the voltage of output is 280～350V, and the duration is 4～5 μ S.
