Abstract

The utility model provides a shock-proof safety socket. When the utility model isn't powered on, the plug is pulled out; the connection wire pole in the plug jack isn't powered on. When using the power, the user only presses the plug, and presses the safety bolt; thus, the connection wire pole can be powered on; the shock-proof safety socket works as a common socket. Thereby, when shock-proof safety socket is powered off, the utility model has the function of shock-proof safety.

Description

Shock-proof safety socket

The utility model provides a kind of safe power connection equipment, mainly is a kind of electric shock-prevention safety socket.

Present common socket has two wiring utmost points more, combines with plug and carries out work.This socket, when not electricity consumption, promptly pull up plug after, the live wire utmost point of the socket internal wiring utmost point is still charged, this is easy to cause electric shock accidents, particularly when curious child plays with jack, the normal pernicious consequence that misfortune and life occur.

The purpose of this utility model is that design is a kind of, after removing plug, and all uncharged safety socket of each supply hub and the plug that has cooperated safety effect with it.

Above purpose is realized by following proposal, the wiring utmost point in the socket, directly be not connected with power supply, and fix by an end, the latch plate that an end lifts joins at stiff end and power supply, and latch plate is provided with safety cock, after pressing down at safety cock, latch plate could be connected with the wiring utmost point, and protrude on safety cock top, can be subjected to the pressure of plug and pressuring spring plate downwards.

Adopt above-mentioned socket, during electricity consumption, plug in, plug will be oppressed safety cock, and circuit has just been connected.When not electricity consumption, unplug, latch plate lifts, and two wiring in the socket are extremely all not charged, even there is staff to take two wires to insert simultaneously in two jacks, electric shock accidents can not take place yet.

Below in conjunction with accompanying drawing, introduce three kinds of embodiment.

Fig. 1 is a schematic diagram of the present utility model.As seen from the figure, socket is made up of the wiring utmost point (1), (2), outer casing upper cover (3), outer casing base (4), set bolt (5), latch plate (6), safety cock (7) etc.The wiring utmost point (1) does not directly join with power supply, and latch plate (6) joins by set bolt (5) and power firestreak, and the direct and zero-power line of the wiring utmost point (2) joins, when not having plug, latch plate (6) is also charged, but does not contact with the wiring utmost point (1), and two wiring are extremely all not charged.When electricity consumption, press plug, safety cock (7) promptly is depressed, and dead spring plate (6) so circuit is connected, can equally with common socket be worked again.

Fig. 2 is the schematic diagram of second kind of embodiment, only be with the difference of first kind of embodiment, its safety cock separated into two parts, a part are in socket, and another part is connected on the plug (8) that cooperates with it that dots, this socket, safety cock does not protrude outside the socket shell, when children's plays with socket, bumps less than safety cock, thereby safer, just plug there is specific requirement.

The third embodiment shown in Figure 3, its safety cock all is connected on the plug (8) that dots, be provided with bar (9) in the safety cock end, when pulling up plug, plug also not exclusively breaks away from socket, and is therefore safer, be applicable to that the electrical equipment that does not take normal changing position uses, in the time of need pulling up plug, can turn on socket cap (3), the former bar (9) that takes off on the safety cock gets final product.Certainly can be according to circumstances without bar (8).

In the foregoing description, its latch plate all has only a slice, therefore, must be connected on the power firestreak.Certainly also can be provided with the latch plate more than two, match with each wiring utmost point respectively, like that, then needn't discern live wire during installation.

Claims

1, the utility model proposes a kind of safe power connection equipment, it mainly is a kind of electric shock-prevention safety socket, be by the wiring utmost point (1), (2), outer casing upper cover (3), outer casing base formations such as (4), it is characterized in that, in socket, be provided with latch plate (6), on spring bearer plate (6), be provided with safety cock (7), one end of spring bearer plate (6) is fixed on the outer casing base (4) of socket by the set bolt that can connect power line (5), the other end can be realized opening and closing movement with the wiring utmost point (1) or (2) under the pressure of safety cock (7), safety cock (7) top is projected into the outer pressure place that can be subjected to plug of socket shell.
