Specific embodiment
Embodiment 1:
Referring to shown in attached drawing 1-2, a kind of disconnecting switch fuse group with shield, including pedestal 1 is set on pedestal 1
There are fuse 4, shield 2, static contact and moving contact, 1 side wall of pedestal is equipped with card slot 11, and card slot 11 is adjacent quiet positioned at two
Between contact, snap-gauge 5 is fixed on pedestal 1 by card slot 11, and snap-gauge is specially T font, and length exceeds the length of static contact,
The electrical isolation of external static contact is improved, snap-gauge 5 is rubber material herein.The structure of moving contact and static contact is the prior art,
Therefore do not add to repeat herein.
Shield 2 includes the long side surface 22 of top surface 21, two and two short sides 23, top surface 21 and two long side surfaces 22 with
And two short sides 23 are cambered surface connection around a cavity 24, the junction in two neighboring face is formed.Top surface 21 is specially one
A cambered surface setting, improves whole aesthetics.
Isolation board 3 is equipped in shield 2, isolation board 3 specifically connects two long side surfaces 22,3 top of isolation board and top surface
21 offset, and the quantity of isolation board 3 is two, and two isolation boards 3 divide shield 2 for three small chambers 25, each small chamber 25
When a corresponding fuse 4, shield 2 and pedestal 1 cooperate, isolation board 3 is isolated by two neighboring fuse 4, prevents from sending out
The accidents such as electricity are climbed in life.The height of isolation board 3 is consistent with two sides herein.
Isolation board 3 is equipped with fixed column 31, and pedestal 1 is equipped with corresponding through-hole, and bolt passes through fixed column 31 and through-hole
Realize the fixation of shield 2 and pedestal 1, the through-hole on pedestal 1 is well-known technique herein, therefore is not drawn into attached drawing.Fixed column 31
Height exceed isolation board 3 height so that playing positioning action in assembling process.
Each isolation board 3 is set there are two fixed column 31, and two fixed columns 31 are symmetrical set, and the structure of fixed column 31 is,
Including upper end 32 and lower end 33, the cross-sectional area of upper end 32 is greater than the cross-sectional area of lower end 33, and upper end 32 is that fixed column 31 is whole
The one third of body is counterbore at the top of upper end 32, so that bolt plays concealment effect in fixation procedure, so that whole beauty
Property improve.Guide surface 321 is equipped at the top of upper end 32 herein, guiding role is played, is entered in fixed column 31 convenient for bolt.
