Abstract
The utility model relates to an anti-electric-shock power plug preventing internal short circuit. The power plug comprises two or more mutually-insulated pins vertically installed on the inner bottom surface of a groove-shaped insulating handle, and insulating sleeves sleeved on the pins. Compression springs are connected between one ends of the insulating sleeves and the inner bottom surface of the insulating handle, wherein the diameter of compression springs is less than the thickness of the insulating sleeves. The power plug has a characteristic that separating plates are extended from the inner bottom surface of the insulating handle and are mutually in parallel with the pins. Because the separating plates are extended from the inner bottom surface of the insulating handle and are mutually in parallel with the pins, the insulating sleeves on the pins and the compression springs are moved between the separating plates and the pins when the power plug is inserted into a socket. Therefore, not only is electric shock injury caused by touching the power plug by mistake in a power plug plugging process prevented, but also power plug damage caused by the short circuit between the internal pins of the insulating handle is effectively prevented, guaranteeing safe and reliable use of the power plug. The compression springs are symmetrically arranged around the pins so that the compression springs are prevented from jamming when moved.

Technical field
The utility model belongs to technical field of electronic components, particularly relates to a kind of protection against electric shock attaching plug that prevents internal short-circuit.
Background technology
Attaching plug is a kind of electronic devices and components that generally use in the productive life, and attaching plug commonly used in the productive life mostly is plug-in type at present, and the grafting copper sheet of attaching plug is exposed in the environment without any safeguard procedures in peg graft preceding and the grafting process.Especially in the grafting process when the grafting copper sheet on the attaching plug has touched copper sheet in the socket, had electric current to pass through on the grafting copper sheet on the attaching plug, and this time hand also by on attaching plug, mistake is bumped and is caused getting an electric shock and hurt sb.'s feelings easily.When attaching plug was not pegged graft, grafting copper sheet long term exposure is easily oxidation or get rusty in environment, can influence the conductive capability when pegging graft to a certain extent.For addressing the above problem, people develop a large amount of protection against electric shock attaching plugs, but still have problem in various degree.As: the attaching plug that directly wraps up the rubber elastomeric material at pin, though solved the problem that electric shock was hurted sb.'s feelings when attaching plug was plugged on supply socket, but owing to wearing out easily, the rubber elastomeric material follows the string, influence the useful life of attaching plug, in addition attaching plug in use rubber elastomeric material fracture instead get an electric shock easily and hurt sb.'s feelings; Also has the attaching plug that is with removable rigid insulation sleeve pipe at pin, structure is the not only fixing compression spring of pin but also fixedly connected insulating sleeve in the groove of insulation handle, solved the problem of getting an electric shock and hurting sb.'s feelings when pegging graft during use equally, but because whole pin one end and compression spring all are arranged in a groove of insulation handle, easily because of the attaching plug internal short-circuit, not only damage attaching plug, also can cause danger because of short circuit.
Summary of the invention
A kind of attaching plug is safe and reliable in the grafting process, a kind of protection against electric shock attaching plug that prevents internal short-circuit of attaching plug long service life for the technical problem that exists in the solution known technology provides for the utility model.
The technical scheme that the utility model adopts is:
Prevent the protection against electric shock attaching plug of internal short-circuit, comprise the pin of two or more mutually insulateds that vertically are installed in groove shape insulation handle inner bottom surface, and be sleeved on the insulating sleeve on the pin; Be connected with two above diameters less than the compression spring of insulating sleeve pipe thickness between insulating sleeve one end and the insulation handle inner bottom surface, be characterized in: described insulation handle inner bottom surface is extended with the dividing plate that is parallel to each other with pin.
The utility model can also adopt following technical scheme:
Distance between described dividing plate and the pin is shaped on the location notch of placing described compression spring greater than the thickness of insulating sleeve tube wall on the insulation handle inner bottom surface.
Described pin is copper sheet, and compression spring symmetry is positioned at around the pin.
Described insulating sleeve is the polyethylene insulation sleeve pipe.
The protection against electric shock attaching plug is when non operating state, and the end face and insulating sleeve one end that insert socket on the pin are same plane.
Advantage and the good effect that the utlity model has are:
1, the utility model is owing to adopted the handle inner bottom surface that will insulate to extend the dividing plate that is parallel to each other with pin, attaching plug is plugged in the socket process, insulating sleeve on the pin and compression spring are mobile between dividing plate and pin, both prevented that touching electricity with the human body mistake in the socket power plug process caused electric shock to be hurted sb.'s feelings, effectively prevented from again having guaranteed when attaching plug uses safe and reliable owing to short circuit between the inner pin of insulation handle causes the damage of attaching plug;
2, the utility model will compress the spring symmetry and be positioned at around the pin, the spring location notch of handle bottom surface insulate in addition, in the attaching plug use, compression spring and insulating sleeve parallel movement on pin, prevented that the phenomenon that gets stuck from appearring in spring and insulating sleeve when moving, further prolong the fail safe of attaching plug, improved the useful life of attaching plug.
3, the utility model protection against electric shock attaching plug is when non operating state, the insertion socket end face of pin and insulating sleeve one end are same plane, prevented effectively that again the pin on the attaching plug from causing stained and oxidation because falling into dust, guaranteed the safe handling of attaching plug.
