Abstract
A lightning-proof safety socket comprises a socket body with jacks and a clamp spring slice that is positioned inside the socket body and suited with a socket needle. The utility model is characterized in that the socket body is provided with lightning-proof protection circuits composed of an absorber, an anti-jamming resistance and two current & temperature limiters. The two current & temperature limiters are respectively connected with two leads in series; the anti-jamming resistance and the absorber are respectively positioned between two leads with the current & temperature limiters; the input of the lightning-proof protection circuits is provided with a joint connected with the municipal electricity, while the outputs of the lightning-proof protection circuits are respectively connected a power-line clamp spring chip and neutral-line clamp spring chip of the socket. The safety socket is scientific in design, simple in structure, strong in practicability, wide in application, and as a power connection for various electrical appliances, the utility model not only avoids the damages to the electrical appliances caused by the natural lightning, but also avoids any damages rising from the cut-off itself. Therefore, the utility model is a new safety socket with the protective function for power system and electrical appliances.
Description
Technical field
The utility model relates to socket, especially a kind of anti-lightning strike safety socket.
Technical background
Along with the raising of people's living standard, increasing household electrical appliance have entered family, and the power supply connection of these household electrical appliances depends on electrical socket usually, just say that also supply socket is the necessity that all kinds of electric equipment products power supplys connect.Existing electric outlet structure is comparatively simple, is made of housing and the jack that inserts for the contact pin of plug disposed thereon, and its function only is the grafting of power supply.
As everyone knows; each electric appliances uses regular meeting often to run into the thunderbolt of the Nature or electric current, spread of voltage situation; too high curtage or thunderbolt can cause the damage of electric equipment products or burn; for avoiding the generation of this situation; a lot of families are that electrical equipment has been equipped with protector; this class protector has the certain protection effect to electrical equipment; but its complex structure; volume is big, price is higher; if each electrical equipment all is equipped with a protector; both can increase expenditure, and can occupy certain usage space to the user.
Summary of the invention
The purpose of this utility model provides a kind of finishing on the function basis that its normal power connects, again the anti-lightning strike safety socket that can regularly cut off the electricity supply rapidly at the thunderbolt that meets with the Nature or electric current, voltage instability.
The anti-lightning strike safety socket of the utility model, comprise: the socket that is provided with jack, be provided with the clamp reed that is used for the connecting plug needle cooperation in the socket, it is characterized in that: be provided with one in the socket by absorber, anti-interference resistance and two anti-lightning strike protective circuits that the current limliting temperature limiter is formed; Described current limliting temperature limiter is serially connected in respectively on two leads, between two leads that are provided with the current limliting temperature limiter respectively and connect anti-interference resistance and absorber; The input of anti-lightning strike protective circuit is provided with the interface that is electrically connected with the city, and output is live wire clamp reed and the center line clamp reed and the ground clamp reed of combination hub respectively.
The operation principle of the anti-lightning strike safety socket of the utility model is: when load is broken down; when voltage, electric current exceed the nominal value of absorber; the absorber two ends produce big electric current immediately; the current limliting temperature limiter is sensed big electric current and is opened circuit immediately; make that electrical equipment is protected on the circuit; during big by the time current vanishes, the current limliting temperature limiter can automatically restore to original conducting state.When appliance plug and the loose contact of this socket cause overcurrent or electric arc, when producing high temperature, the current limliting temperature limiter is sensed big electric current and is opened circuit immediately, makes that electrical equipment is protected on the circuit.When electrical network is struck by lightning or electrical network when breaking down, when voltage or electric current have exceeded the nominal value of the automatic absorber of meeting, absorber two ends moments presents short-circuit condition, thereby produce big electric current, making the current limliting temperature limiter produce opens circuit, break through absorber simultaneously, the spike that is produced by thunderbolt in the circuit is absorbed.
The anti-lightning strike safety socket design science of the utility model, simple in structure, practical, applied widely, with the mains connection of this anti-lightning strike safety socket as each electric appliances, the damage that both can avoid the Nature thunderbolt to bring to electrical equipment, the also damage that can avoid electrical equipment itself to open circuit and may cause.It is a kind of new type of safe socket that electrical network and electrical equipment is all had protective effect.
The concrete structure of the anti-lightning strike safety socket of the utility model is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is anti-lightning strike safety socket electricity theory structure schematic diagram.
Embodiment
Embodiment: the contour structures of anti-lightning strike safety socket is identical with existing common power socket, and its difference is that inside has increased anti-lightning strike protective circuit, thereby has constituted this anti-lightning strike safety socket.Anti-lightning strike safety socket comprises: the socket that is provided with jack, be provided with the clamp reed that is used for the connecting plug needle cooperation in the socket, be provided with one in the socket by absorber 1, anti-interference capacitor C1 and two anti-lightning strike protective circuit (see figure 1)s that current limliting temperature limiter TF1, TF2 form; Described current limliting temperature limiter TF1, TF2 are serially connected in respectively on live wire 2 and the center line 3, are serially connected with live wire 2 and 3 in the center line of current limliting temperature limiter TF1, TF2 and connect anti-interference resistance C1 and absorber 1; The input of anti-lightning strike protective circuit is provided with interface a, the b that is electrically connected with the city, and output is live wire clamp reed A and the center line clamp reed B and the ground clamp reed E of combination hub respectively.Described absorber 1 is made of three piezo-resistance V1, V2, V3, the end of three piezo-resistance V1, V2, V3 interconnects, the other end of forming piezo-resistance V1 behind the absorber 1 and V2 is attempted by 3 in live wire 2 and center line, the ground clamp reed E of the other end combination hub of piezo-resistance V3.Indicator light DS1 and resistance R 1 are gone back and be connected to the live wire 2 and 3 in the center line that are serially connected with current limliting temperature limiter TF1, TF2.
Claims (3)
1, a kind of anti-lightning strike safety socket, comprise: the socket that is provided with jack, be provided with the clamp reed that is used for the connecting plug needle cooperation in the socket, it is characterized in that: be provided with one in the socket by absorber, anti-interference resistance and two anti-lightning strike protective circuits that the current limliting temperature limiter is formed; Described current limliting temperature limiter is serially connected in respectively on two leads, between two leads that are provided with the current limliting temperature limiter respectively and connect anti-interference resistance and absorber; The input of anti-lightning strike protective circuit is provided with the interface that is electrically connected with the city, and output is live wire clamp reed and the center line clamp reed and the ground clamp reed of combination hub respectively.
