Abstract
The utility model relates to an electric shock protection plug, which comprises a casing, metal plug-in pieces and a connecting wire, wherein the casing adopts a column structure, and the metal plug-in pieces extend out of the bottom surface of the casing; a circle of slot is formed inwards from the periphery of the bottom surface of the casing, a cylindrical housing is connected inside the slot via a spring, and the length of the cylindrical housing is bigger than that of the metal plug-in pieces. During installation of the plug, the metal plug-in pieces are aligned to plug jacks and slowly pressed downwards, the cylindrical housing is pressed to gradually retract into the slot during the pressing process, and the metal plug-in pieces are completely inserted into the plug jacks to be electrified; when the plug is pulled out, the cylindrical housing on the surface of the casing is ejected by the spring at the moment the metal plug-in pieces are separated from the plug jacks, so as to gradually and completely cover the metal plug-in pieces to form protection, thereby avoiding the risk that a hand touches the metal plug-in pieces while inserting in or pulling out the plug. The utility model has the advantages of simple structure, convenient and practical use, wide application, reasonable process, etc.
Description
Technical field
The utility model relates to a kind of electric equipment, especially a kind of electric shock resistant plug.
Background technology
As everyone knows, plug is the topmost conductive components of various electric equipments.But the metal insert of plug is exposed on the external fully at present, and when carrying out plug on socket, hand is easy to contact with metal insert, causes electric shock accidents, and is especially dangerous especially for the child.In order to address the above problem, we provide a kind of electric shock resistant plug.
Summary of the invention
The purpose of this utility model provides a kind of electric shock resistant plug, is used to solve the problem that ordinary plug causes Danger Electric shock risk easily.
For achieving the above object, the utility model electric shock resistant plug comprises shell, metal insert and connecting line, and shell is a column structure, and metal insert stretches out from the shell bottom surface; Inwardly offer a circle slot from the shell bottom periphery, connect the tubular outer cover at the slot inner spring, and the length of tubular outer cover is greater than metal insert length.
After adopting said structure, corresponding with receptacle sockets when assigning plug metal insert, slowly to push downwards then, the tubular outer cover is squeezed gradually in the retraction slot in the extrusion process, but metal insert inserts just energized of receptacle sockets fully; When pulling up plug, after metal insert broke away from receptacle sockets, the tubular outer cover of case surface can be ejected by spring, covered metal insert gradually until covering fully, formed protection, avoided the danger that hand contacts with metal insert in the plug process.
Compared with the prior art, the beneficial effects of the utility model are: simple in structure, convenient and practical, be widely used, technology is reasonable, can improve the plug fail safe, reduces the electric shock accidents occurrence probability.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model electric shock resistant plug.
Number in the figure: 1 is that shell, 2 is that metal insert, 3 is that connecting line, 4 is that slot, 5 is that spring, 6 is outer cover.
Embodiment
