Abstract

The utility model discloses a safety plug which can avoid electric shock during an unplugging process. The safety plug comprises a casing (1), two protective tube sliding ways (2) are arranged in the casing (1), a spring (3) and a protective tube (4) are arranged in each protective tube sliding way (2) which is connected with the protective tube (4) through the spring (3) arranged between the internal surface of the protective tube sliding way (2) and the bottom surface of the protective tube (4) , and an electrode pin (5) penetrates through each protective tube (4) and is connected with a binding post (6) at one end. The safety plug is suitable for access to the electricity or electric conduction of various electrical appliances.

Description

Safety plug
Technical field
The utility model relates to a kind of plug, in particular, relates to a kind of safety plug of getting an electric shock when unplugg, can avoided.
Background technology
Plug in the market can be used for the power taking or the conduction of various electrical equipment in use, but in the process of pulling the plug out of the socket, hand is run into exposed electrode pins easily and caused getting an electric shock.Up to the present, a kind of plug of getting an electric shock in the process of pulling the plug out of the socket, can avoided does not appear on the market as yet.
The utility model content
The purpose of the utility model be to existing plug in withdrawal process, hand is run into exposed electrode pins and the phenomenon that causes getting an electric shock easily, and a kind of safety plug that gets an electric shock when unplugg, can avoided that provides.
The safety plug of the utility model comprises housing; Be provided with two protection tube sliding channels in the said housing; Be provided with spring and protection tube in the said protection tube sliding channel, the protection tube sliding channel links to each other with protection tube through spring, and spring is arranged between the bottom faces of inside face and protection tube of protection tube sliding channel; Have electrode pins to pass in the said protection tube, an end of described electrode pins links to each other with binding post.
Said protection tube sliding channel is cylindrical; Said protection tube diameter is less than the protection tube sliding channel; Can in the protection tube sliding channel, be free to slide; The cross section of said electrode pins is a rectangle, and said protection tube is the hollow circular-tube that insulating material is processed, and the length that said protection tube stretches out housing is stretched out the long 2-5mm of length of housing than electrode pins.
The beneficial effect of the utility model is: (1) is simple in structure, is easy to make; (2) practical, get an electric shock in the time of can effectively avoiding unplugg.
Description of drawings
Fig. 1 is the internal structure sketch map of the utility model;
Among the figure: housing 1, protection tube sliding channel 2, spring 3, protection tube 4, electrode pins 5, binding post 6.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
In the drawings, the safety plug of the utility model mainly is made up of housing 1, protection tube sliding channel 2, spring 3, protection tube 4, electrode pins 5 and binding post 6.
Be provided with two protection tube sliding channels 2 in the said housing 1; Be provided with spring 3 and protection tube 4 in the said protection tube sliding channel 2; Protection tube sliding channel 2 links to each other with protection tube 4 through spring 3; Said spring 3 is arranged between the bottom faces of inside face and protection tube 4 of protection tube sliding channel 2, has electrode pins 5 to pass in the said protection tube 4, and an end of described electrode pins 5 links to each other with binding post 6.
Said protection tube sliding channel 2 is cylindrical; Said protection tube 4 diameters are less than protection tube sliding channel 2; Can in protection tube sliding channel 2, be free to slide; The cross section of said electrode pins 5 is a rectangle, the hollow circular-tube that said protection tube 4 is processed for insulating material, and the length that said protection tube 4 stretches out housing 1 is stretched out the long 3mm of length of housing 1 than electrode pins 5.
During use, when electrode pins 5 was inserted jack, protection tube 4 was pressed in the protection tube sliding channel 2; Simultaneously spring 3 is compressed, and when pulling the plug out of the socket, protection tube 4 is extracted and released by spring 3 simultaneously with electrode pins 5; Electrode pins 5 does not expose in protection tube 4 all the time, reaches to avoid the purpose of getting an electric shock.
