Abstract
The invention discloses an anti-dropping plug which comprises a plug body and a plurality of metal wafers. A sucker is arranged on the plug body, the plurality of metal wafers are arranged on the plug body and located in the sucker, a sucker switch is arranged on the plug body, and the sucker switch and the sucker are connected through an air guide pipe arranged in the plug body. By means of the mode, the anti-dropping plug can prevent loose of the plug and a socket caused by external force or untight matching.
Description
Technical field
The present invention relates to field of electronic devices, particularly relate to a kind of drop-proofing plug.
Background technology
Use increasing electronic equipment in people's daily life, work, a plurality of electronic equipments are connected on multipurpose socket or extension socket with using plug being connected of power supply more.All need to use power line on all household electrical appliance, be used for being connected with power supply.The structure of power line comprises electric wire and the plug that links together, and plug is used for plugging with household electrical appliance or supply socket.In the use procedure of reality, plug needs to plug operation with household electrical appliance or supply socket sometimes.It is all direct connection between existing plug and socket, often between the size of some plug and socket because small difference can cause being connected between plug and socket not tight, easily get loose, and often plug can because of the stressed landing from the socket of unexpected situation, affect the useful life of electronic device very much.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of drop-proofing plug, can prevent between plug and socket because of external force or coordinate untight former thereby get loose.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of drop-proofing plug is provided, comprise: header body and a plurality of metal contact piece, be provided with sucker on described header body, described a plurality of metal contact piece is arranged on header body and is positioned at sucker inside, be provided with the sucker switch on described header body, connect by wireway between described sucker switch and sucker, described wireway is arranged on header body inside.
In a preferred embodiment of the present invention, the quantity of described metal contact piece is 2 or 3.
In a preferred embodiment of the present invention, described wireway one end is connected with sucker, and the other end is connected on the sucker switch.
In a preferred embodiment of the present invention, be provided with guide groove on described header body, described wireway is equipped with in guide groove.
In a preferred embodiment of the present invention, the cross section of described header body is rounded, and the diameter of described sucker is less than the diameter of header body.
The invention has the beneficial effects as follows: drop-proofing plug of the present invention can prevent between plug and socket because of external force or coordinate untight former thereby get loose.
Description of drawings
Fig. 1 is the structural representation of drop-proofing plug one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, header body, 2, metal contact piece, 3, sucker, 4, the sucker switch, 5, wireway.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
See also Fig. 1, a kind of drop-proofing plug, comprise: header body 1 and a plurality of metal contact piece 2, be provided with sucker 3 on described header body 1, described a plurality of metal contact piece 2 is arranged on header body 1 and is positioned at sucker 3 inside, be provided with sucker switch 4 on described header body 1, connect by wireway 5 between described sucker switch 4 and sucker 3, described wireway 5 is arranged on header body 1 inside.
In addition, the quantity of described metal contact piece 2 is 2 or 3, and a plurality of metal contact pieces form two hole plugs or three hole plugs.
In addition, described wireway 5 one ends are connected with sucker 3, and the other end is connected on sucker switch 4, and sucker switch 4 cuts out or open wireway 5, are used for air inlet or hold one's breath.
In addition, be provided with guide groove on described header body 1, described wireway 5 is equipped with in guide groove, and wireway 5 is used for to sucker 3 air guides.
In addition, the cross section of described header body 1 is rounded, and the diameter of described sucker 3 is less than the diameter of header body 1.
Drop-proofing plug specific works principle of the present invention is as follows: plug is inserted on socket, close sucker 3 switches, this moment, sucker 3 was adsorbed on socket, open sucker switch 4 when not needing to use, then air enters sucker 3 by wireway 5, then inside and outside air pressure balance, sucker 3 unclamps socket, pulls up plug and both can.
Be different from prior art, drop-proofing plug of the present invention can prevent between plug and socket because of external force or coordinate untight former thereby get loose.
The above is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
