Abstract

The utility model discloses a safety socket. A pair of spring pieces is arranged on the inner side of a metal piece slotting. The middles of the upper parts of the spring pieces are respectively provided with a trapezoid switch. The power supply is connected to the spring pieces. The upper part of the switch is provided with a push rod which is higher than the cover surface of the socket. The utility model has the advantages of safety, simple structure, and convenient use. The generation of the electric shock accident of the children caused by wrong inserting the metals such as the iron nail, etc., is avoided.

Description

Safety socket

The utility model relates to electrotechnical apparatus, is a kind of socket that is used for household appliances, specifically, is a kind of socket of getting an electric shock of preventing.

Along with the raising of people's living standard, the electrical equipment in the family is more and more, and the socket of use is also increasing.In the socket that existing market is sold, all directly be connected to power supply.Children insert socket with iron nail or other metals, and people touch sheet metal accidentally when inserting or transfer to plug, are shocked by electricity even electric shock accidents often has generation.Therefore various safety sockets are invented in succession, but all have complex structure, the cost height, or use inconvenient shortcoming.

This practical purpose provides a kind of simple in structure, easy to use, the socket of safety.

The purpose of this utility model is to solve as follows: two flat spring sheets are equipped with in the sheet metal inboard in socket, between spring leaf and the sheet metal certain intervals is arranged, on the spring leaf, the screw that connects power supply is housed, above the two spring leaf centres, the trapezoidal switch that has a usefulness bakelite or other hard materials to make certainly, also can be conical, one aperture is arranged below the switch, little spring is equipped with in the inside, and a bar-shaped shape push rod is arranged at switch top, and push rod exceeds at the socket capping by the aperture on the socket cover.Certainly also push rod can be installed in the middle of the plug bottom.

Advantage of the present utility model: when plug did not insert socket fully, the sheet metal in the jack was not charged, and children promptly use iron nail two iron nails to insert socket and electric shock accidents can not take place.Or careless hand touches the plug copper sheet and also can not have an accident during plug insertion socket.Have only the plug of working as to insert fully, switch presses down, and spring leaf is pressed to both sides, and is just charged on the sheet metal, guarantees the electrical equipment electricity consumption.

Below in conjunction with drawings and Examples the utility model is further elaborated:

Fig. 1 is a kind of structure side view of the present utility model.

Fig. 2 is a kind of structure vertical view of the present utility model.

Fig. 3 is an another kind of structural representation of the present utility model.

Fig. 1, Fig. 2 describe an embodiment of the present utility model, at socket base plate 1, on the slot that two sheet metals curve is housed, two flat spring sheets 3 are housed in the sheet metal inboard, spring leaf can become with steel or copper.Spring leaf one end respectively is equipped with a contact 4, and relative position also can be loaded onto a contact on sheet metal certainly.The spring leaf other end is equipped with the screw 5 that connects power supply.Between sheet metal and the spring leaf certain clearance is arranged.The trapezoidal switch 6 that has a bakelite or other insulating material to make on two spring leaf centres certainly, also can be made cone.One hole 7 is arranged at the switch bottom, and spring 8 is housed in the hole.One push rod 10 is arranged at switch top, and the push rod end is by socket cover 13, on hole 9, exceed capping.Jack 14 on the socket surface, the slot that curves with sheet metal is relative.

Fig. 3 has described another embodiment of the present utility model, becomes the plane on the trapezoidal or conical switch top of insulation, and push rod 10 is installed in plug 11, in the middle of the bottom, with socket cover 13, on hole 8, corresponding.

Use of the present utility model and principle are as follows:

Sheet metal is not owing to directly connect power supply, thus when just inserting jack, touches by plug the plug copper sheet accidentally, or children insert socket with metal, electric shock accidents can not take place.When plug inserted fully, the base plane of plug was compressed into push rod, and two inclined-planes of trapezoidal switch press to both sides with spring leaf, and the contact is contacted with sheet metal.Because be connected to power supply on the spring leaf, at this moment the plug copper sheet just has.Another embodiment is the push rod of plug bottom, by the hole on the capping trapezoidal switch is depressed.

Claims

1, a kind of safety socket, it is characterized in that: two flat spring sheets are equipped with in socket sheet metal inboard, spring leaf one end respectively is equipped with a contact, the spring leaf other end, the screw that connects power supply is housed, the trapezoidal or conical switch of an insulation is arranged on two spring leaf centres, a hole is arranged at the switch bottom, spring is housed in the hole, and a push rod is arranged at switch top.

2, safety socket according to claim 1 is characterized in that: the push rod on switch top is by the hole on the socket cover, high capping.

3, safety socket according to claim 1 and 2 is characterized in that, push rod can be installed in the middle of the plug bottom, and is corresponding with the hole on the socket cover.

4, safety socket according to claim 1 is characterized in that: with on the corresponding sheet metal in spring leaf contact the contact is housed also.
