This utility model provide a kind of automatic change-over contact system open away from excess of stroke tunable arrangement, including adjustable drawbar, connecting rod, connecting shaft, moving contact, static contact, main shaft and buckling nut；Main shaft and connecting rod are connected by steady pin, can be freely rotatable, adjustable drawbar one end and connecting rod are threaded by self, the other end of adjustable drawbar and connecting shaft are threaded by self, connecting shaft is arranged on the strap of moving contact, can rotate freely action, static contact is fixed on the pedestal of Switch main body；Specifically, one end that adjustable drawbar is connected with connecting rod is right-handed thread；The other end that adjustable drawbar is connected with connecting shaft is left hand thread.More preferably, adjustable drawbar is furnished with buckling nut.This utility model passes through adjustable drawbar, rotates adjusting yoke, changes the physical length that adjusting yoke connects, and changes the angle that moving contact rotates, thus realizes switching out away from, the regulation of the excess of stroke.
Description
Technical field
This utility model relates to a kind of automatic change-over contact system, especially a kind of automatic change-over contact system
Open away from excess of stroke tunable arrangement.
Background technology
Opening of existing PC level automatic change-over can not regulate away from, the excess of stroke, after switch assembling completes, finds because of machine
The dynamic/static contact that tool machining accuracy, error and rigging error are brought leaves away from, the excess of stroke inconsistent, needs to be difficult to when adjusting implement,
One pole is so caused to open away from, excess of stroke technical parameter the most right, the most asynchronous etc., greatly reduce the electric property of product.
After at switch, assembling completes, need to carry out out away from, excess of stroke regulation, it is ensured that opening of one pole contact conforms to away from, the excess of stroke
Ask, the most also ensure that switching the action of each pole synchronizes, and improves the electric property of switch.
Summary of the invention
For the deficiencies in the prior art, this utility model provide a kind of automatic change-over contact system open away from
Excess of stroke tunable arrangement, by adjustable drawbar, rotates adjusting yoke, changes the physical length that adjusting yoke connects, change moving contact
The angle rotated, thus realize switching out away from, the regulation of the excess of stroke, it is ensured that switch meets the requirements at technical parameter, switchs reliable work
Make.The technical solution adopted in the utility model is:
A kind of automatic change-over contact system open away from excess of stroke tunable arrangement, including adjustable drawbar, connecting rod, connect
Axle, moving contact, static contact, main shaft and buckling nut；
Main shaft and connecting rod are connected by steady pin, it is possible to freely rotatable, and adjustable drawbar one end and connecting rod are by self
Threaded, the other end of adjustable drawbar and connecting shaft are threaded by self, and connecting shaft is arranged on the fixation clamp of moving contact
On plate, it is possible to rotate freely action, static contact is fixed on the pedestal of Switch main body；
The screw thread left-right rotary at adjustable drawbar two ends is in opposite direction.
Specifically, one end that adjustable drawbar is connected with connecting rod is right-handed thread；It is another that adjustable drawbar is connected with connecting shaft
One end is left hand thread.
More preferably, adjustable drawbar is furnished with buckling nut.
The utility model has the advantage of:
1) processing of parts is simple, it is not necessary to special tool(s), need not adjust on a large scale after having switched again；
2) by left rotation and right rotation adjustable drawbar, the most simply achieve switch and open and do not meet technology requirement away from, the excess of stroke
A difficult problem.
3) different current specification can also be realized split away from, requirement that the excess of stroke is different.
Accompanying drawing explanation
Fig. 1 is that structure of the present utility model forms schematic diagram.
Fig. 2 is Switch main body of the present utility model and static contact schematic diagram.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
This utility model provide automatic change-over contact system open away from excess of stroke tunable arrangement, such as Fig. 1 and Fig. 2 institute
Show, including adjustable drawbar 1, connecting rod 2, connecting shaft 3, moving contact 4, static contact 5, main shaft 6 and buckling nut 7；
Main shaft 6 and connecting rod 2 are connected by steady pin, it is possible to freely rotatable, and adjustable drawbar 1 one end and connecting rod 2 are passed through
Self is threaded, and is right-handed thread, and adjustable drawbar 1 is furnished with buckling nut 7, the other end of adjustable drawbar 1 and connection
Axle 3 is threaded by self, and is left hand thread, and connecting shaft 3 is arranged on the strap of moving contact 4, it is possible to freely
Spinning movement, static contact 5 is fixed on the pedestal of Switch main body, and such main shaft 6 rotates, and is finally promoted dynamic touching by the transmission of power
4 spinning movements, complete switch and close point.
Adjustable drawbar 1 two ends are all screw thread, and one end is left hand thread, and the other end is right-handed thread, so, adjustable when rotating
During pull bar 1, the adjustable drawbar 1 distance between connecting rod 2 and connecting shaft 3 can change, and when dextrorotation, distance can shorten,
When left-handed, distance can be elongated, and at this moment under the power effect of main shaft 6 transmission, moving contact 4 and then rotates, but what moving contact 4 rotated
Angle is also the most different, thus realizes opening away from, the adjustment of the excess of stroke.
When switch leaves and strengthens adjustment away from needs, opening buckling nut 7, dextrorotation adjustable drawbar 1, by specialty during adjustment
Feeler gauge measurement open away from, after distance meets the requirements, with spanner rotating latch nut 7, it is ensured that till locked, thus increase out
Close open away from.
When switch leaves and reduces adjustment away from needs, opening buckling nut 7, left-handed adjustable drawbar 1, by specialty during adjustment
Feeler gauge measurement open away from, after distance meets the requirements, with spanner rotating latch nut 7, it is ensured that till locked, thus increase out
Close open away from.
When dextrorotation adjustable drawbar 1, this end of right-handed thread is reducing the distance, and the other end of adjustable drawbar 1 is left hand thread,
At this moment it is left-handed in fact to this end, then if left hand thread is left-handed, is also to reduce the distance, just achieves the contracting of distance
Short.Achieve increasing large opening.
When left-handed adjustable drawbar 1, this end of right-handed thread is increasing distance, and the other end of adjustable drawbar is left hand thread,
At this moment it is dextrorotation in fact to this end, then if left hand thread dextrorotation, is also to increase distance, just achieving the increasing of distance
Add.Achieve reduction open away from.
This completes switch and open away from descending, ascending regulation process, such control method is the simplest
Single, convenient easily operation, and reliably.
In this utility model, the rotatory force of mechanism action is all provided by the electromagnetic system of switch own.
