Description
Technical field
The utility model relates to a kind of plug, especially a kind of changeover plug, belongs to " the connection of H01R conductivity in International Patent Classification (IPC); The textural association of the electrical connecting element of one group of mutually insulated; Jockey; Current-collector " technical field.
Background technology
Along with the development of traffic, go abroad and become a comparatively general thing, but countries in the world cause the use of electronic equipment could must be realized by changeover plug by electric standard difference.Various countries' different electrical power plug or certain state's attaching plug can be converted to another country or multinational power source plug by changeover plug, multinational or a state attaching plug can be inserted in the socket of another one country.Make the plug of country variant can arrive the intercommunication of global country variant energy, the electrical equipment solving global country variant can arrive other country and use.Chinese patent 200910096707.6 discloses a kind of cover-turning intelligent mobile power converter, comprises protective casing, cover-turning type safety door, safety door switch, socket, attaching plug; Described socket is arranged on inside protective casing, protective casing is provided with emergency exit and the safety door switch by cover-turning type safety gate control; Open cover-turning type safety door and could contact socket inside protective casing, cover-turning type safety door is opened, and safety door switch automatic cut-off power input is to the power supply of socket, and socket does not have electricity, makes the operation of the carrying out plug plug of user security; Close cover-turning type safety door, and safety door switch switches on power the power supply of input to socket automatically, and socket has electricity; Protective casing also has wire casing, and the power line of electrical appliance plug is drawn through crossed beam trunking and is led to electrical appliance.Which provide a kind of safer cover-turning intelligent mobile power converter, but this cover-turning intelligent mobile power converter volume is large, carries inconvenience, and not easily detachable problem after there is plug and socket grafting.
Summary of the invention
In view of this, it is little that the utility model object is to provide a kind of volume, easy to carry, use safety and can the changeover plug extracted of convenient plug.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of changeover plug, the lid comprising header body and be flexibly connected with this header body, described header body comprises insulator foot, the bottom of this insulator foot is provided with three pins, the upper end of wherein said insulator foot extends a boss vertically upward, and the upper end of described boss is fixedly installed metal contact piece, and one end of this metal contact piece is connected with the contact in groove shapes; The both sides of described boss are respectively equipped with alignment pin, and described lid is connected with described boss is convertible by described alignment pin, and described lid front end is also provided with the draw-in groove fastened with described contact.
Preferably, above-mentioned changeover plug, the both sides of wherein said lid are respectively equipped with and described alignment pin size, lid ear that shape is corresponding, and described lid is connected with described alignment pin buckle by described lid ear, and freely can overturn around described alignment pin.
Preferably, above-mentioned changeover plug, wherein said metal contact piece stretches out and protrudes from described boss.
Preferably, above-mentioned changeover plug, the top ring of wherein said boss is provided with linear grooves around described metal contact piece, and the inner surface of described lid is provided with the linear bar body matched with described linear grooves.
Preferably, above-mentioned changeover plug, wherein said boss is little compared with described insulator foot, and is provided with hollow hole in described insulator foot marginal portion, and described lid is also provided with thermovent.
Preferably, above-mentioned changeover plug, wherein said contact and described metal contact piece one-body molded.
Technique effect of the present utility model is mainly reflected in: when in the utility model, the draw-in groove of lid front end engages with contact, metal contact piece is sandwiched between boss and lid, and to engage position with contact in draw-in groove and form wire casing and be used for and plug grafting to be converted, because metal contact piece is covered by insulating material completely, fully ensure that its fail safe used, the both sides of boss are respectively equipped with alignment pin simultaneously, lid is connected by alignment pin and boss are convertible, directly can overturn lid be convenient to extracting of plug when needing to extract plug to be converted.
Accompanying drawing explanation
Fig. 1: the utility model structural representation;
Fig. 2: the utility model structure vertical view.
