Property inwardly rollover tears open to form two parallel surfaces for piece end, form compound shell fragment 602, compound shell fragment is provided with spacing salient point 601, protect
Shell fragment service life is demonstrate,proved without failing.
Application method one：Plug base 5 is by action bars 1001 from this product（Abbreviation converter）In skid off, pole pin is revealed
Go out and fix in position, when not needing earth polar latch, rotate the certain angle of shell-like latch 7 by hand（Angular range be 45 °~
135 °), the limited step 704 and positive stop spring plate 6 for making shell-like latch 7 fail, and gently press shell-like latch 7, as the two poles of the earth plug
Converter, it is adaptable to the pole socket of respective country two.When shell-like latch 7 is pressed, the wedge angle on the head of shell-like latch 7 is with being located at guide pillar
3 or ground pole base 2 on triangular ramp contact, after the stress of shell-like latch 7, slide and rotate on inclined-plane, until shell-like is inserted
Limited step 704 on pin 7 is consistent with the direction of positive stop spring plate 6, realizes the spinning reduction of shell-like latch 7, and Plug base 5 pushes back production
When in product, limited step 704 is clasped with positive stop spring plate 6 again, when Plug base 5 is skidded off from converter next time, shell-like
The limited step 704 of latch 7 is just limited shell fragment 6 and blocked, it is not necessary to which user operates again can just make converter have earth polar
Latch, referring to Figure 15, Figure 16, is and so on used.
Application method two：Plug base 5 is skidded off by action bars 1001 from converter, and pole pin is exposed and is fixed to
Position, when not needing earth polar latch, pressing shell-like latch 7, the limited step 704 with gradient is under force by positive stop spring plate
Flick, shell-like latch 7 can just be slided along guide pillar 3, so as to be retracted into converter inside, form inserting for no earth polar latch
Head.When Plug base 5 is pushed back in converter, limited step 704 is clasped with positive stop spring plate 6 again, next time by Plug base 5 from
When being skidded off in converter, the limited step 704 of shell-like latch 7 is just limited shell fragment 6 and blocked, it is not necessary to which user operates again can
To make it have earth polar latch.And so on.
Further, this product is used as the expansion of multinational converter, and enclosure is designed to two spaces, shell it is upper
Portion space sets jack assemblies 11, and lower space is provided with the plug-assembly 10 of multiple country variant standards.Wherein, jack assemblies
11 sleeves 9 for including sleeve seat and being arranged in sleeve seat, as shown in Figure 18,19, correspondence sleeve 9 is provided with jack on shell, with
Just inserted for plug.Plug-assembly 10 include multipurpose plug pedestal, and multipurpose plug pedestal be fixed with L, N pole latch and
Action bars 1001, as shown in figure 17, shell corresponding plug component 10 are provided with through hole, so that the earth polar on plug-assembly 10 is inserted
Pin can be from inside stretching, and action bars 1001 can drive latch to be stretched out from inside for stirring multipurpose plug pedestal.It is right
Can be independent design in the ground pole base of multinational converter, it would however also be possible to employ sleeve seat is used as ground pole base.
Multinational converter application method one：Plug-assembly 10 is fully accommodated in the lower space of enclosure at the beginning,
Plug-assembly 10 is driven to move downward by stirring action bars 1001 when needing to use so that earth polar latch stretches out from inside, and
It is while having L, N pole and earth polar latch after stretching.When not needing earth polar latch, one angle of earthing pole latch is rotated by hand
Degree（Angular range is 45 °~135 °), the limited step and positive stop spring plate for making earth polar latch fail, and gently press earthing pole and insert
Pin, is now the two poles of the earth plug, it is adaptable to the pole socket of respective country two.When in earth polar, latch is pressed, the point on earthing pole latch head
Angle is contacted with the triangular ramp on guide pillar or pedestal, after earthing pole latch stress, is slided on inclined-plane, until earthing pole
Limited step on latch is consistent with positive stop spring plate direction, realizes the spinning reduction of earth polar latch, if user needs to use band
The plug of earth polar latch, it is only necessary to stir action bars 1001 and plug-assembly is recovered in the inner space of shell so that be spacing
Step and the spacing connection of positive stop spring plate, then stir action bars 1001 and push down on plug-assembly again so that latch can be from
Inside is stretched out, so that it may make plug-assembly while having L, N pole and earth polar latch.
Multinational converter application method two：Plug-assembly 10 is fully accommodated in the lower space of enclosure at the beginning,
Plug-assembly is driven to move downward by stirring action bars 1001 when needing to use so that electrode latch can stretch out from inside,
And it is while having L, N pole and earth polar latch after stretching.When not needing earth polar latch, earthing pole latch is pressed, makes to connect
The limited step of earth polar latch struts positive stop spring plate, spacing failure, in earthing pole latch retract product, is now inserted for the two poles of the earth
Head, it is adaptable to the pole socket of respective country two.If user needs to use the plug with earth polar latch, it is only necessary to stir action bars
1001 are recovered to plug-assembly the inner space of shell so that limited step and positive stop spring plate are fastened and connected, and then dial again
Dynamic action bars pushes down on plug-assembly so that latch can from inside stretching, so that it may make plug-assembly at the same have L, N pole and
Earth polar latch.
Above-described embodiment is the description of the invention, is not limitation of the invention, any simple transformation to the present invention
Structure, method afterwards belongs to protection scope of the present invention.
