The utility model discloses be equipped with first from reset switch, second from reset switch and double knives single -throw switch, only socket circular telegram under the equal closed circumstances of three switch, greatly reduced the probabilities that get an electric shock of children, the security that has improved the socket.

Description

Safety electric shock-prevention socket

Technical field

This utility model relates to a kind of socket, particularly to a kind of safety electric shock-prevention socket.

Background technology

The children from getting electric shock accident that socket causes in recent years is in ascendant trend year by year, and adult is because the electric shock that socket improper use or carelessness cause also happens occasionally.The most common socket does not has electroshock-proof function, main protection against electric shock measure to be to use socket protection cover, uses highly inconvenient, and anti-electric shock socket price is costly, and the effect of protection against electric shock is unknown.

Summary of the invention

In order to solve above-mentioned technical problem, this utility model provides the safety electric shock-prevention socket that a kind of simple in construction, protection against electric shock are effective.

nullThis utility model solves the technical scheme of the problems referred to above: a kind of safety electric shock-prevention socket，Including housing and the first self-resetting switch of being arranged in housing、Second self-resetting switch and double-pole single throw，Housing is provided with zero line jack and firewire jack，Zero line jack sheet metal and firewire jack sheet metal it is respectively equipped with in zero line jack and firewire jack，Described first self-resetting switch、Second self-resetting switch is separately fixed at bottom zero line jack and firewire jack，Described double-pole single throw has the first stationary contact、First movable contact、Second stationary contact and the second movable contact，First movable contact of double-pole single throw is connected with firewire jack sheet metal，First stationary contact of double-pole single throw is connected with live wire after the first self-resetting switch，Second stationary contact of double-pole single throw is connected with zero line jack sheet metal，Second movable contact of double-pole single throw is connected with zero line after the second self-resetting switch.

In above-mentioned safety electric shock-prevention socket, the control end of described double-pole single throw is arranged on housing and between zero line jack and firewire jack.

The beneficial effects of the utility model are: this utility model is provided with the first self-resetting switch, the second self-resetting switch and double-pole single throw, three switches constitute zero line loop and live wire loop, only socket energising in the case of three switches all Guan Bis, and the plug of electrical appliance must be completely inserted in zero line jack and firewire jack by three switch all Guan Bis, this is relatively difficult for the child that consciousness of behavior is the strongest, therefore greatly reduce the probability of children from getting electric shock, improve the safety of socket.

Detailed description of the invention

With embodiment, this utility model is further described below in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, this utility model includes housing 3 and the first self-resetting switch S1 being arranged in housing 3, the second self-resetting switch S2 and double-pole single throw S3, housing 3 is provided with zero line jack 5 and firewire jack 4, being respectively equipped with zero line jack sheet metal 1 and firewire jack sheet metal 2 in zero line jack 5 and firewire jack 4, described first self-resetting switch S1, the second self-resetting switch S2 are separately fixed at bottom zero line jack 5 and firewire jack 4.

As shown in Figure 1, Figure 3, described double-pole single throw S3 has the first stationary contact, the first movable contact, the second stationary contact and the second movable contact, first movable contact of double-pole single throw S3 is connected with firewire jack sheet metal 2, first stationary contact of double-pole single throw S3 is connected with live wire L after the first self-resetting switch S1, second stationary contact of double-pole single throw S3 is connected with zero line jack sheet metal 1, and second movable contact of double-pole single throw S3 is connected with zero line N after the second self-resetting switch S2.The control end of described double-pole single throw S3 is arranged on housing 3 and between zero line jack 5 and firewire jack 4.

Operation principle of the present utility model is as follows: double-pole single throw S3 is equivalent to main switch, when it disconnects, no matter whether the first self-resetting switch S1, the second self-resetting switch S2 close, be all uncharged in jack, i.e. two handss of human body or hand-held metal object puts in zero line jack 5 and firewire jack 4 all without electric shock accidents occurs simultaneously；If double-pole single throw S3 is triggered, control due to the second self-resetting switch S2 in firewire jack 4 is the break-make of zero line, what the first self-resetting switch S1 in zero line jack 5 controlled is the break-make of live wire, so, even if finger puts in firewire jack 4 or zero line jack 5 all without electric shock accidents occurs.But in the case of double-pole single throw S3 closes, finger puts in the risk having electric shock in two jacks simultaneously, but, people only has two handss, the probability simultaneously triggering three switches for the child that consciousness of behavior is the strongest is the lowest, therefore can effectively prevent the generation of children from getting electric shock accident.And owing to when the plug of electrical appliance inserts half, three switches are not triggered, so, even if now adult carelessly touches the metal part of plug, also it is the risk not having electric shock.

Even if this utility model human body during plug plug touches plug metal pin and also will not get an electric shock, on the one hand prevent adult's imprudence when plugging plug from touching the electric shock that plug metal part causes, on the other hand can allow the plug plug of children's safety.And this socket jack when not in use is uncharged, child so can be avoided because of curiosity finger or to put in jack by metal object and the electric shock accidents that causes.
