Do not have a power failure and change table plug seat
Technical field
The present invention relates to a kind of electric energy meter mounting base, especially a kind of do not have a power failure to change table plug seat and the company for plugging seat
Connect device.
Background technology
It is typically that the naked of conducting wire is gone out partly to fill in electric power meter end bore that traditional electric energy meter couples with power lead, this
The conducting wire of connection mode and the connection of electric power meter end sub-aperture be not firm, and current lead-through rate is low, and heat dissipation effect is poor, and dismounting is dumb.
For this reason, have devised a kind of Special mounting seat for electric energy meter standard wiring plugs seat, to solve the above problems.It is but this
The plug seat of electric energy meter, it is necessary to cut off the power, causes relevant electrical equipment to have a power failure, have impact on electric appliance when replacing electric energy meter
The normal operation of equipment, the electrical equipment that cannot arbitrarily have a power failure for which is even more to bring serious consequence.
The content of the invention
The object of the present invention is to provide a kind of do not have a power failure to change table plug seat and connector for plugging seat.
The present invention is to solve existing electric energy meter plugs seat when replacing electric energy meter, it is necessary to cut off the power, cause phase
The electrical equipment of pass has a power failure, the problem of have impact on the normal operation of electrical equipment.
It is of the present invention do not have a power failure change table plug seat technical solution be:It includes box body, between box body is equipped with
Every the current terminal of arrangement, the current terminal front end is stretched out in outside box body, and the current terminal rear end is located in box body,
The box body top of the current terminal rear end is equipped with grafting window, and cover board is stamped on the grafting window.
It is of the present invention be used to not having a power failure change the technical solution of connector of table plug seat and be:It includes connecting seat, institute
The connecting seat lower part stated is equipped with least a pair of conductive pin, which is connected with each other, and is set in the outside of conductive base pin
There is spats.
It is an advantage of the invention that:It has current lead-through rate high, and fever is few, and electric energy loss is small, can be with when replacing ammeter
Without power-off, the normal operation of electrical equipment is not influenced, it is convenient to replace, fast.

Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in the figure, of the present invention do not have a power failure changes the plug seat of table and include box body 4, four are equipped with arranged on box body 4
The current terminal 1 of spaced and parallel arrangement, 1 front end of current terminal are stretched out in outside box body 4,1 rear end of current terminal
In box body 4,4 top of box body of 1 rear end of current terminal is equipped with grafting window 9, is stamped on the grafting window 9
Plate 7.Each current terminal rear end is longitudinally through grafting window.
The first sealing ear 2 is equipped with the middle part of 9 inner side edge of grafting window, avris is equipped with hook groove 11, the cover board 7
Middle avris is equipped with the second sealing ear 8, and avris is equipped with hook 5;The cover board 7 is inserted into hook groove 11 by hook 5 and covered
The first sealing ear 2 and second seals ear 8 and overlaps after on grafting window, covering, and the described first sealing ear 2 and second seals ear
8 are equipped with mounting hole 3.
The front side of box body 4 is arc-shaped side along side, and the avris of the box body 4 is equipped with sideline hole 10, along sideline Kong Chu
Box body be equipped with side protection modeling tooth;The front side of box body 4 is equipped with preceding string holes 6, and preceding protect is equipped with along the box body at preceding string holes 6
Shield modeling tooth.
A kind of connector that table plug seat is changed for not having a power failure of the present invention, including connecting seat, the connection
Seat lower part is equipped with the conductive base pin at two pairs of intervals, and each pair pin includes the conductive base pin of two spaced and parallel arrangements and this two are led
Electrical prongs are connected with each other, and spats 18 is equipped with the outside of conductive base pin.The conductive base pin is inverted U pin.On connector
The spacing that the spacing of two pairs of conductive base pins changes the plug seat current terminal of table with not having a power failure matches.
The each pair conductive base pin is put together by inner spring piece 15 and outer spring piece 16.The inner spring piece 15 2
End is respectively equipped with interior R types foot, and 16 2 end of outer spring piece is respectively equipped with outer R types foot.Inner spring piece 15 and outer spring piece
After 16 splits, the interior R types foot of inner spring piece one end forms this in conductive base pin against the outer R types foot of outer spring piece the same end
One, the interior R types foot of the inner spring piece other end forms this in conductive base pin against the outer R types foot of the outer spring piece other end
Another, this to conductive base pin since two ends of inner spring piece and two ends of outer spring piece are conductings, so this is to conduction
Pin is also conducting.
The connecting seat includes protecgulum 14 and rear cover 13, and the protecgulum 14 and rear cover 13 mutually cover.The box
4 avris of body is equipped with LED light 12, and the LED light 12 is connected with conductive base pin.The connecting seat is equipped with two
Shake hands hole 17.
The present invention application method be:When needing replacing electric energy meter, opening, which does not have a power failure, changes grafting window on table plug seat
Cover board, expose grafting window, then the inverted U pin of connector be inserted into four current terminals being exposed in plate window
On, at this moment current terminal two or two connects, and LED light is lighted;When extracting electric energy meter, protection power source connection is remained to, thus
Directly electric energy meter can be replaced in the state of not having a power failure.After the completion of replacing electric energy meter, connector is pulled up, and change table not having a power failure and insert
Pull out in the cover plate lid of seat, again to sealing ear sealing.
