Specific embodiment
For the ease of it will be appreciated by those skilled in the art that making to the present invention further in detail below in conjunction with accompanying drawing and embodiment
Thin description.
Fig. 1-Figure 10 is refer to, the embodiment of the present invention includes：
A kind of protection against electric shock wall socket with load control unit, including housing, the spatial load forecasting being arranged in housing
Device 7 and protection against electric shock module；Housing includes bottom 1, cover 2；Protection against electric shock module include be arranged on bottom 1 wiring copper post 11,
Contact copper sheet component 3, the protection block assembly 4 being connected with wiring copper post 11, protection block assembly 4 are arranged on contact copper sheet component 3
Side, electric shock copper sheet component 3 includes fixed touch plate 31 and movable contact flat 32, and movable contact flat 32 is driven by protection block assembly 4；Protection block
Component 4 includes the insertion hole protection door of integral type, and insertion hole protection door is provided with jack inclined-plane；Copper sheet 12 is inserted with wiring copper post 11.
Insertion hole protection door includes the two circle flat insertion hole protection doors 42 of insertion hole protection door 41 and three；Wherein two circle insertion hole protection doors 41
Jack inclined-plane 411 and jack inclined-plane 412 are provided with, three flat insertion hole protection doors 42 also are provided with jack inclined-plane 421 and jack inclined-plane 422,
It is extremely corresponding with the L and N on socket respectively.
The wall socket of the present embodiment, is provided with well-designed, clever structure protection against electric shock module, and one piece of integral type jack is protected
Shield door, it is necessary to while being promoted from two jacks, the movement of insertion hole protection door could be promoted, so that movable contact flat is touched with fixed
Piece is contacted so that fixed touch plate is powered.In a piece conductor insertion jack, insertion hole protection door only shifts, and displacement very little, no
It is enough to drive the movement of movable contact flat, i.e. fixed touch plate to be separated with movable contact flat, jack inside contact is not charged, will not produce tactile
The danger of electricity, greatly reduces the generation of electric shock phenomenon.In particularly living, many children out of curiosity, miss potter and use metal
Plate insertion jack is played, and in this case, this wall socket ensure that children do not get an electric shock, and be effectively protected the life of children
Life safety, with practicality very high.
Protection block assembly 4 from top to bottom includes insertion hole protection door, jack sliding block 43 and acts on insertion hole protection door successively
On return spring 44, insertion hole protection door include two circle the flat insertion hole protection doors 42 of insertion hole protection door 41 and three, two circle jacks protection
41 bottoms of door are provided with card convex 413, and the bottom of three flat insertion hole protection door 42 is provided with card convex 423, and jack sliding block 43 is provided with draw-in groove 431 and draws

Fixed touch plate is powered, and electric power is delivered to plug and finally reaches electrical appliance, and socket is normally outwards powered.Load control unit is set
Below switch key, because the part for switching position is less, load control unit may be provided at the lower section of switch, there is provided fill
The installing space of foot；On the other hand, load control unit closes on switch, makes load control unit with the line alignment of switch
Layout is easier.
After plug is transferred to, insertion hole protection door is moved in the opposite direction in the presence of return spring, and returns to original position,
Now jack inclined-plane is completely covered on fixed touch plate top, and fixed touch plate completely cuts off with female receptacle.When single jack has foreign matter to insert
When, protection door can only shift, and displacement very little, be not enough to drive the movement of jack sliding block and movable contact flat, fixed
Contact is still not charged, even if therefore foreign matter contacted with fixed touch plate and also do not result in electric shock.
Housing also includes securing cover plate 5 and the upper lid 6 of support, and securing cover plate 5 is close to the lower section of cover 2, and lid 6 is close in support
Below securing cover plate 5；Lid 6 is provided with switch activity key 61 in support, and being provided with switch at the bottom 1 of the lower section of switch activity key 61 touches
Piece connection sheet 13, the lower surface of lid 6 is provided with protection block assembly installation position in support.
Load control unit 7 includes overload protective device 71 and overload protective device SR 72.With patent publication
A kind of load control unit of smart jack of 102324347A is similar, and the wall socket of the present embodiment provide not only anti-touching
The characteristic of electricity, and possess that kind of sensitivity is high, breaking speed fast, long lifespan, socket load control unit stable and reliable for performance.
Finally it should be noted that above example illustrates technical scheme, rather than to the scope of the present invention
Limitation, although being explained to the present invention with reference to preferred embodiment, it will be understood by those within the art that,
Technical scheme can be modified or equivalent, without deviating from the essence and model of technical solution of the present invention
Enclose.
