Concrete meaning in the present invention.
By inventor the study found that the moving contact of existing HR20 types low-voltage fusing switch (low pressure switch with knifeshaped fuse) is chimeric
Part is that copper sheet closes a floodgate by multiple, cannot often be directed at card slot, impact card slot piece, so that card slot piece is damaged, serious conditions card slot
Piece moves, and leads to clip-type moving contact poor contact loosening when closing a floodgate of low-voltage fusing switch (low pressure switch with knifeshaped fuse);HR20 types
The upper moving contact usage time of equal low-voltage fusing switchs (low pressure switch with knifeshaped fuse) is long, and pedestal upper static contact copper intermediate plate is loosened and connect
It touches bad, leads to that voltage is low, robs phenomena such as fire;Closing operation is needed compared with great dynamics.
Low-voltage fusing switch (low pressure switch with knifeshaped fuse) divide-shut brake number repeatedly, using clip-type moving contact and copper sheet after duration connects
It touches and loosens;Operating personnel's drawing low-voltage fusing switch (low pressure switch with knifeshaped fuse) disconnecting link more when need, compared with great dynamics, and to be difficult to judge
Whether in place to close a floodgate;Low-voltage fusing switch "on" position, conductivity be not high.

151 nuts far from the spring one end are resisted against the first moving contact intermediate plate 110 far from the second moving contact intermediate plate 120
One side on.
In the present embodiment, when fuse cutout is closed, static contact is clamped in the first moving contact intermediate plate 110 and described second
Between moving contact intermediate plate 120, the elastic portion 152 of the Elastic Bolts 150 gives the moving contact 100 intermediate plate, one elastic force, from
And enable the moving contact 100 that the static contact is tightly clamped.
In the present embodiment, the moving contact 100 includes two Elastic Bolts 150, and two Elastic Bolts 150 are mounted on described
The both sides of lug boss.
In the present embodiment, 100 intermediate plate of the moving contact is symmetrical structure.
In the present embodiment, the moving contact 100 includes two Elastic Bolts 150, and two Elastic Bolts 150 are symmetrically mounted on
The both sides of the lug boss.
The Elastic Bolts 150 make arch copper intermediate plate contact fixation with static contact copper sheet, and the elastic force of spring is plus arch
It is light that power superposition allows staff to carry out closing operation while so that low-voltage fusing switch is closed a floodgate solid and reliable.Operating personnel are not necessarily to
Excessive dynamics drawing low-voltage fusing switch more can be pulled open easily, close low-voltage fusing switch.
After experiment is repeatedly pulled open, closes low-voltage fusing switch, it is still secured that the dynamic tactile intermediate plate contact of shape is drawn in low pressure fusing
Reliably, compared with the prior art in low-voltage fusing switch (low pressure switch with knifeshaped fuse) clip-type moving contact it is more solid and reliable, electric conductivity
More preferably.
The moving contact 100 of the present invention passes through the lug boss by the way that 100 intermediate plate of the moving contact is provided with lug boss
It is better contacted with the static contact of the fuse cutout to solve the problems, such as moving contact 100 and static contact poor contact.
In the present embodiment, the dynamic tactile intermediate plate of low-voltage fusing switch arch, using opposite arch intermediate plate, in addition Elastic Bolts apply
Elastic force meets mechanics and carves type elastic force bonding principle, keeps operating personnel's drawing low-voltage fusing switch lighter and low-voltage fusing switch
Clip-type moving contact contacts more secured with low-voltage fusing switch clip-type static contact.Operating personnel fuse without excessive dynamics drawing low pressure
Switch, more can easily pull open, close low-voltage fusing switch.After experiment is repeatedly pulled open, closes low-voltage fusing switch, low pressure
Fusing draws the dynamic tactile intermediate plate of shape and contacts still solid and reliable, the folder of the low-voltage fusing switchs (low pressure switch with knifeshaped fuse) such as opposite HR20 types
Type moving contact is more solid and reliable, using the dynamic tactile intermediate plate of low-voltage fusing switch arch, makes low-voltage fusing switch (low pressure switch with knifeshaped fuse)
Dynamic/static contact contact area increases, and electric conductivity is high.
The embodiment of the present invention provides a kind of fuse cutout.As shown in Figures 3 and 4, the fuse cutout includes:Mounting base
200, insulation column, plug-in strip 400, moving contact 100 and static contact 500.
