Description

Safety socket and plug

The utility model relates to a kind of safety socket, plug.

Existing socket and plug generally have two-phase and three-phase, the jack that the structure of its socket is opened by housing, housing upper end, be installed in the conductive metal sheet in the jack, fixedly the screw of conductive metal sheet and power lead, installing hole constitute, and the structure of plug is made of the plug blades of transverse plane under handle and the vertical handle.During the work of this plug, socket the plug blades of plug is inserted in the exposed jack, plug blades contacts i.e. connection with conductive metal sheet in the jack.Because the conductive metal sheet of existing socket can directly be seen, in human iron wire or electric conducting material insertion jack, with the conductive metal sheet that contacts in the jack, thereby the people is got an electric shock, and occurs this situation when particularly child plays easily, so very dangerous.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of exposed jack that do not have is provided, and inserts the safety socket and the supporting with it plug that also can not get an electric shock in the socket with electric conducting material.

Solution of the present utility model is: socket comprises housing, conductive metal sheet, fixedly screw, the installing hole of conductive metal sheet and power lead, it is characterized in that having a jack in the housing upper end, one gag that can stretch is up and down arranged in the jack, and conductive metal sheet is fixed on the housing at hole wall edge.Gag can be made of with the spring that the lid lower end is connected the lid of upper end, the spacing block set of lid two side ends in the solution of the present utility model, and spacing block set moves in the groove of the housing adjacent with gag, on the lid of the present utility model a positioning table can be arranged.

The plug that uses that matches with the utility model socket is made of handle and plug blades, is characterized in connecting a plug neck under the handle, and plug blades is fixed on the plug neck, and parallel with plug neck bottom face.Plug neck center bottom can be opened a pit in the solution of the utility model plug, correspondingly can cooperate the location with the positioning table of socket cover, skids when preventing the tamponade lid.

The course of work of the present utility model is: when not inserting plug, gag surface and housing upper surface in one plane, at this moment whole socket does not see that jack is arranged; When plug insertion socket, because gag can stretch up and down, the inside indentation of gag under the plug neck effect of plug, the plug neck and the plug blades of corresponding plug enter in the jack, rotate plug, decontrol the power that is applied on the plug, under the effect of scalable gag, plug blades contacts with conductive metal sheet on being fixed on Socket walls edge housing, and moves on the restriction plug, thus conducting.When taking off plug, rotate when plug makes plug blades be returned to direction of insertion and can take off.

The utility model has the advantages that because when not inserting plug, jack is not exposed, it in the jack gag, and conductive metal sheet is fixed on the housing at hole wall edge, so in jack, can't directly see, put in also and can't directly touch from jack by conductive metallic material, thereby prevented that the electric shock incident of when child plays electric conducting material being inserted in the socket from taking place, and has very high fail safe.Plug of the present utility model, socket can be made three-phase and two-phase, can replace existing plug, socket.

The utility model can further specify in conjunction with the accompanying drawings.
