Abstract

The utility model discloses an anti-electric shock safety socket and plug, and relates to the technical field of sockets. The anti-electric shock safety socket and plug is provided with a socket and a plug; the socket consists of a bottom plate and a hollow cylinder fixed on the bottom plate; a rotary table capable of rotating is arranged at the bottom of the hollow cylinder, and two electrodes are symmetrically fixed on the rotary table; two radial grooves are arranged on the inner wall of the hollow cylinder corresponding to two sides of the electrodes; axial grooves are arranged at the bottoms of the two radial grooves along the same direction of the inner wall; the arc length of the axial grooves is quarter of the arc of the hollow cylinder; two binding posts are fixed on the bottom plate; when not in work, the two electrodes and the two binding posts are in a crossed shape; when in work, the two electrodes are connected with two binding posts; the plug is matched with the hollow cylinder, and provided with plug holes matched with the electrodes; and limiting blocks matched with the radial grooves are respectively installed on the surface of the plug corresponding to the plug hole. The anti-electric shock safety socket and plug has the advantages of simple structure and good safety performance.

Description

A kind of electric shock-prevention safety socket and plug

Technical field

The utility model relates to the jack technology field, specifically is that a kind of protection against electric shock is assigned seat and plug entirely; The safety utilization of electric power that can be applicable to family, enterprise and other field connects.

Background technology

Along with the modernization process paces, household electrical appliance and industrial production power consumption equipment constantly increase, but there is very big potential safety hazard in the common socket of existing electric equipment, and people touch charged conductor easily, thereby electrification takes place to use; And existing more existing safety sockets are not that design is complicated, and cost of manufacture is higher; Be exactly relatively simple for structure, do not have the effect of safeguard protection.

Summary of the invention

In order to solve the shortcoming of above-mentioned prior art, the utility model provides a kind of electric shock-prevention safety socket and plug; Simple in structure and can realize that the safety of electric equipment and power supply is connected.

The utility model is realized with following technical scheme: a kind of electric shock-prevention safety socket and plug comprise a socket and plug; Described socket has a base plate, fixes a hollow cylinder on the base plate; In the bottom of hollow cylinder rotary rotating disk is installed, be symmetrically fixed with two electrodes on the rotating disk, on the hollow cylinder inwall of electrode both sides correspondence, have two radial grooves, have axial notch two radial groove bottoms along the same direction of inwall, the axial notch arc length is 1/4th of a hollow cylinder circular arc; Be fixed with two binding posts on base plate, two binding posts are connected with external power source; In the time of idle, be crosswise between two electrodes and two binding posts; In the time of work, two electrodes are connected with two binding posts; Described plug is the plug that matches with hollow cylinder, is separately installed with the guide vane end stop that matches with radial groove on the plug surface that has the jack that matches with electrode and jack correspondence on the plug.

The beneficial effects of the utility model are: socket is not when using, and inner electrode is uncharged fully, can effectively avoid electric shock accidents; Simple in structure, practical.

Embodiment

As depicted in figs. 1 and 2, a kind of electric shock-prevention safety socket and plug have a socket 1 and plug 2; Socket 1 has a base plate 11, fixes a hollow cylinder 12 on the base plate 11; Rotary rotating disk 6 is installed in the bottom of hollow cylinder 12, be symmetrically fixed with two electrodes 3 on the rotating disk 6, on hollow cylinder 12 inwalls of electrode 3 both sides correspondences, have two radial grooves 4, have axial notch 5 along two same directions of radial groove 4 bottom interior wall, axial notch 5 arc length are 1/4th of hollow cylinder 12 circular arcs.Plug 2 is the plugs that match with hollow cylinder 12.

As shown in Figures 2 and 3, two radial grooves 4, one of them adopts semi-circular recesses, and another adopts rectangular recess.Be fixed with 7, two binding posts 7 of two binding posts is connected with external power source in the bottom of base plate 11; When not working, be crosswise between two electrodes 3 and two binding posts 7, differ 90 °; During work, two electrodes 3 are connected with two binding posts 7.

As shown in Figure 4 and Figure 5, on the plug surface that has the jack 22 that matches with electrode 3 and jack 22 correspondences on the plug 2, be separately installed with the guide vane end stop 21 that matches with radial groove; Guide vane end stop 21 make plug 2 can with socket 1 firm linking together, prevent to become flexible.During work for prevent plug 21 li revolution of socket cause the outage, two spring contacts 23 also are installed on plug 2; Spring contact 23 and jack 22 are cross-shaped.

The course of work: the binding post 7 of socket 1 bottom is connected with external power source, and the electrode 3 of socket inside is connected with electric equipment.The binding post 7 of the electrode of socket 1 inside and socket bottom is cross-shaped at ordinary times, is in complete off-state, and the electrode of socket inside is uncharged, can not cause any danger like this.During use, plug 2 is inserted in the hollow cylinders 12 along radial groove 4, make the binding post 7 of socket 1 bottom be connected with its internal electrode 3 by rotation, circuit turn-on at this moment, spring contact 23 and guide vane end stop 21 make plug 2 be fixed on this position.During disconnection, press plug 2 gently, rotation is extracted and is got final product.
