Abstract
The utility model discloses a novel plug, including casing, outer access line, ground wire inserted bar, live wire inserted bar and zero line inserted bar, outer access line setting in the rear end of casing, the one end of ground wire inserted bar, live wire inserted bar and zero line inserted bar stretch out in front end, the other end of casing insert the casing access line electric connection outside with, its characterized in that: the live wire inserted bar one end of inserting the casing be provided with the static contact, the rear end of the casing position that corresponds the ignition line inserted bar be provided with the button, the button be connected with the spring, the spring setting in the inside of casing, the one end of spring relative key be provided with the moving contact, be in when pressing the state when the button, moving contact and static contact contact. This design simple structure, it is practical convenient, rigorously enforce operating specification, make the electric outer casing reliable ground, prevent the electric shock accidents, in addition, even this design can not extracted by the plug, also make and cut off the power supply totally with electrical apparatus, avoid the standby to produce energy loss.
Description
Technical field
The utility model relates to plug field, in particular to a kind of new type of plug.
Background technology
Three-hole socket install time, below holes connects power line, and zero line connects left hole, and phase line connects right hole, above macropore connect protective earthing line.The ground connection string holes of socket then contacts three-pin plug the thickest the longest inserted link, then receives the metal shell of electrical equipment by inserted link.The earth connections of all will plugging into such as such as washing machine, refrigerator, electric iron.
Earth connection does not have electric current under normal circumstances.But once electrical leakage, electric current just flows into ground from shell through earth connection.Because the resistance of the resistance ratio human body of earth connection is much smaller, therefore the electric current of the overwhelming majority enters ground along this linear flow, and the electric current flowing through human body is just little of safe range.
Thus: when three-pin plug inserts Three-hole socket, first plug spring hole scoket, guarantee metal shell first ground connection, if electrical appliance electric leakage, human body, by earth short, prevents electric shock accidents;
But in practical operation, people often have ignored the importance of operating sequence, cause there is many danger: if when three-pin plug inserts Three-hole socket, first insert left hole socket, first live wire is connected with electrical appliance, if electrical appliance leaks electricity, can there is electric shock accidents in human contact's electrical appliance meeting indirect contact live wire.
In addition, the socket of existing wiring board is intensive, once all be utilized or interface tension, plug is caused not to be drawn out easily, pressure is extracted and can be produced potential safety hazard, and this is a problem of having a bad headache, and causes a lot of user to be disinclined to the plug of electrical equipment to be pulled up, electric equipment products are standby consumes electric energy, causes unnecessary waste.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides simple, practical and convenient, the strict working specification of a kind of structure, prevent from getting an electric shock, power-off flexibly, avoid standby produce power loss safety pin.
The technical solution of the utility model: a kind of new type of plug, include housing, outer tie-in line, ground wire inserted link, live wire inserted link and zero line inserted link, described outer tie-in line is arranged on the rear end of housing, one end of described ground wire inserted link, live wire inserted link and zero line inserted link stretches out in the front end of housing, the other end inserts in housing and is electrically connected with outer tie-in line, and one end of described live wire inserted link insertion housing is provided with fixed contact; The position that the rear end of described housing correspond to live wire inserted link is provided with button, described button is connected with spring, and described spring is arranged on the inside of housing, and one end of described spring relative key is provided with moving contact, when button is in down state, moving contact and fixed contact contact.
The further technical scheme of the utility model is: be provided with insulation cushion between described spring and moving contact.
The further technical scheme of the utility model is: the outer wall of described housing is provided with antislip cog.
Compared with prior art, the advantage of new type of plug of the present utility model is:
1, because ground wire inserted link is arranged on the front end of housing, although live wire inserted link and zero line inserted link also stretch out in the front end of housing, because live wire inserted link does not connect wire, so like this, in the operation of plug insertion socket, ensure that ground wire inserted link first connects, make the metal shell reliable ground of electrical equipment, once electrical leakage, electric current just flows into ground from shell through earth connection.
2, action button, make fixed contact and the moving contact joint of live wire inserted link, live wire inserted link is made to be linked in circuit, electrical equipment just accesses power supply, the access order of strict like this three-pin plug, specification Electrical Safety, prevents because first live wire to be connected with electrical appliance and the generation of electric shock accidents can occur.
3, action button, makes fixed contact and moving contact reset, is in released state, even if plug is not extracted like this, also can makes the complete power-off of electrical appliance, avoid standby produce power loss.

Fig. 1 structural representation of the present utility model.
In figure: 10, housing, 20, outer tie-in line, 30, ground wire inserted link, 40, live wire inserted link, 41, fixed contact, 42, moving contact, 50, zero line inserted link, 60, spring, 70, button.
Embodiment
Referring to accompanying drawing, provide embodiment of the present utility model, be used for being further described formation of the present utility model.
New type of plug as shown in Figure 1, include housing 10, outer tie-in line 20, ground wire inserted link 30, live wire inserted link 40 and zero line inserted link 50, outer tie-in line 20 is arranged on the rear end of housing 10, one end of ground wire inserted link 30, live wire inserted link 40 and zero line inserted link 50 stretches out in the front end of housing 10, the other end inserts in housing 10 and is electrically connected with outer tie-in line 20, and one end that live wire inserted link 40 inserts housing 10 is provided with fixed contact 41; The position that the rear end of housing 10 correspond to live wire inserted link 40 is provided with button 70, button 70 is connected with spring 60, and spring 60 is arranged on the inside of housing 10, and one end of spring 60 relative key 70 is provided with moving contact 42, when button 70 is in down state, moving contact 42 and fixed contact 41 contact.
