Compared with the prior art, the utility model has the advantages of structural performance is gone with in saving cost, location, keeping under the unanimous circumstances of original auxiliary switch appearance size, can rise to 3 divisions 3 and close or 4 divisions 4 close.
Description
Technical field
This utility model relates to belonging to Low Voltage Electrical Apparatus, especially relates to a kind of auxiliary switch and opens with auxiliary
The chopper closed.
Background technology
The auxiliary switch assembling being presently using is cumbersome, and space availability ratio is the highest, two moving contacts of general employing,
Thus cause relatively costly.Chinese patent CN101436493B discloses a kind of auxiliary switch for circuit breaker, including
Microswitch in the housing that is fitted to each other for a pair, the shell chamber being located at housing and be similarly located at the shell chamber of housing
Driving member, driving member is constituted and has the first contact arm of the haptic element for activating described microswitch and composition to be stuck in
For the second contact arm activated for circuit breaker operation mechanism outside housing, on the first contact arm, composition has for touching continuously micro-
First, second work surface of the haptic element of dynamic switch, wherein, the first work surface is formed on the upper surface of the first contact arm,
And the second work surface is formed on the top end face of the first contact arm.But this kind of auxiliary switch structure is relative complex, therefore
Cost is the most of a relatively high, it is impossible to spread uses.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and provide one to save into
This, location and the good auxiliary switch of structural behaviour and the chopper with auxiliary switch.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of auxiliary switch, including
Moving contact component, is positioned at housing central section, including at least three moving contact,
It is positioned at the static contact component of moving contact component both sides, is connected with outer lead,
The cover plate that lid is located at outside housing, shape matches with housing.
Described moving contact component is made up of moving contact, push rod, push rod back-moving spring, roller and touch spring, institute
The moving contact stated is connected on push rod, and described push rod stretches out housing, and described push rod back-moving spring is set in push rod
The section of stretching out and be connected on housing, described roller is connected to the external part of push rod, the two of described touch spring
End abuts moving contact and push rod respectively.
The equal riveted of upper and lower surface at described moving contact both ends has silver point.
Described static contact component is made up of upper static contact and lower static contact, respectively with moving contact end upper and lower surface
Silver point is corresponding, so can shorten the distance between upper static contact and lower static contact, thus improve single auxiliary and open
The group number closed, single auxiliary switch is opened 2 by 2 and is closed and make 3 into and open 3 and close or 4 open 4 and close.
Described static contact component changes original screw with outer lead and docks, welded connection.
A kind of chopper, including this kind of auxiliary switch.
When auxiliary switch push rod is promoted from bottom to top by this utility model by external force, change touching on moving contact component
The angle of head spring, and moving contact is transformed into lower stationary contact by upper static contact by the dynamics rotated down by touch spring
Head, thus realize the conversion between the normally-open normally-close of the conversion between static contact, i.e. auxiliary switch.
Compared with prior art, this utility model has the advantage that
1, cost-effective: in the case of keeping original auxiliary switch external form in the same size, 3 can be risen to and open
3 close or 4 open 4 and close, and originally simply 2 open 2 and close, and single auxiliary switch the most often organize only has two moving contacts,
Connect push rods by two cross structures, 4 will be realized and open 4 and close two groups of moving contact assembly of needs and could realize, present
Need one group of moving contact just can realize 4 to open 4 and close；
2, positioning performance is good: on the cover board increases boss location, has had the position of static contact and cover plate well
Location.
3, structural behaviour is good: static contact, with embedded assembling, improves efficiency of assembling, and secondly static contact is with outside
Lead-in wire uses the form docking of welding, it is ensured that the reliability of contact.Also reduce cost simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of auxiliary switch；
Fig. 2 is the structural representation of moving contact component.
In figure, under 1-housing, 2-upper static contact, 3-, static contact, 4-push rod, 5-moving contact component, 6-push rod are again
Position spring, 7-roller, 8-axle, 9-moving contact, 10-touch spring.
Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment
A kind of auxiliary switch, its structure is as it is shown in figure 1, include the moving contact component 5 being positioned in the middle part of housing 1, position
In the static contact component of moving contact component 5 both sides, and lid is located at the cover plate outside housing 1, shape and housing 1
Match.
The structure of moving contact component 5 is as in figure 2 it is shown, by moving contact 9, push rod 4, push rod back-moving spring 6, roll
Son 7 and touch spring 10 form, and moving contact 9 can arrange 3-4, is connected on push rod 4, moving contact 9
The equal riveted of upper and lower surface at both ends has silver point.Static contact component is made up of upper static contact 2 and lower static contact 3, point
The most corresponding with the silver point of moving contact 9 end upper and lower surface, so can shorten upper static contact 2 and lower static contact 3
Between distance, thus improve the group number of single auxiliary switch, single auxiliary switch is opened 2 by 2 and is closed and make 3 into and open 3
Close or 4 open 4 and close.The present embodiment is 3 open 3 and close.Static contact component changes original screw pair with outer lead
Connect, welded connection.
Push rod 4 stretches out housing 1, and push rod back-moving spring 6 is set in the section of stretching out of push rod 4 and is connected on housing 1,
Roller 7 is connected to the external part of push rod 4 by axle 8, the two ends of touch spring 10 abut respectively moving contact 9 and
Push rod 4.
Auxiliary switch disclosed in the present embodiment can be applied on-board the circuit breaker, during use, by external force by auxiliary switch
Push rod 4 when promoting from bottom to top, change the angle of touch spring 10 on moving contact component 5, and by touching
Moving contact 9 is transformed into lower static contact 3 by upper static contact 2 by the dynamics that head spring 10 rotates down, thus realizes
Conversion between static contact.
