Abstract
The invention provides a safety power plug with a surrounded automatic extending and retracting insulating sleeve. According to a plug body, an insulating sleeve of which the width is equal to the length of an insert and which surrounds the insert is arranged around the insert, and the insulating sleeve can automatically extend and retract in the plug body in the plugging and pulling process of the plug with the aid of an elastic device. The surrounded automatic extending and retracting insulating sleeve can completely surround the insert in the plugging and pulling process of the plug, so that the problem of unsafety caused by contact between fingers and the insert is avoided.
Description
Technical field
The present invention relates to a kind of attaching plug.
Background technology
Existing attaching plug, its inserted sheet is completely exposed, or half is exposed.This kind of attaching plug very easily causes the danger of getting an electric shock because of hand and blade contact in the process of plug, there is hidden danger.
Summary of the invention
The invention provides a kind of enclosed automatic telescopic insulating case safety powr supply plug, solve existing power supply plug because its inserted sheet is completely exposed or half exposed the produced unsafe problems causing electric shock in the process of plug plug.
The present invention includes the slotting body of plug and enclosed automatic telescopic insulating case and elastic force apparatus, the technical scheme adopted is: described slotting body is provided with the insulating case of the height encirclement inserted sheet identical with inserted sheet length around inserted sheet, and this insulating case relies on elastic force apparatus automatically can stretch in slotting body in plug swapping process.
Beneficial effect of the present invention is: in the process of plug plug, can surround inserted sheet completely by enclosed automatic telescopic insulating case, avoid unsafe problem that finger brings with blade contact.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Accompanying drawing 1 is a kind of structural representation of the present invention, and accompanying drawing 2 is another kind of structural representations of the present invention.
Embodiment
Shown in accompanying drawing 1 embodiment: described slotting body 1 is provided with the insulating case 3 of the height encirclement inserted sheet 2 identical with inserted sheet 2 length around inserted sheet 2, and this insulating case 3 relies on elastic force apparatus 4 automatically can stretch in slotting body 1 in plug swapping process.
Shown in accompanying drawing 2 embodiment: described slotting body 5 is provided with the insulating case 7 of the height encirclement inserted sheet 6 identical with inserted sheet 6 length around inserted sheet 6, and this insulating case 7 relies on elastic force apparatus 8 automatically can stretch in slotting body 5 in plug swapping process.
