Abstract
The utility model discloses a disconnecting switch's static contact, including stationary contact headstock, left contact and right contact, the left side upper portion of stationary contact headstock is equipped with the slide opening that runs through in the stationary contact headstock, the inside arch piece that is fixed with in left side of stationary contact headstock, the left side of left side contact is fixed with the litter that inserts in the slide opening, the right end pin of protruding piece has connect the commentaries on classics board, the upper and lower both ends of changeing the board respectively through spring coupling on the inside left surface of the left surface of left contact and stationary contact headstock, the bottom of right side contact is run through the stationary contact headstock and is connected with and connects electricity end, and this static contact makes left contact sticis on touching the sword through the cooperation of changeing between board and the spring to making the contact touched between sword and the static contact inseparabler, making electric conductive property reach best effect, touching sword plug in -process moreover, left contact is pressed in the pressure that touches the sword and to be changed, makes the contact of switch effectual and easily choose.
Description
Technical field
This utility model is related to switch fitting technical field, specially a kind of static contact of chopper switch.
Background technology
Switch static contact includes fixed contact pedestal and two static contacts, and two static contacts are arranged on fixed contact pedestal, static contact
Contacted by contact knife for a long time, affected electric conductivity.The static contact of existing chopper switch is all often oneself of dependence static contact
Body elastic force and clamp contact knife, with gradually relaxing of static contact its own resilient, lead to the loose contact of contact knife and static contact, and
Contact knife, during disconnecting, often leads to be difficult to easily cut off the electricity supply because the chucking power of static contact is excessive, for this reason,
A kind of static contact of chopper switch is proposed.
Utility model content
The purpose of this utility model is to provide a kind of static contact of chopper switch, to solve to propose in above-mentioned background technology
Problem.
For achieving the above object, this utility model provides a kind of following technical scheme: static contact of chopper switch, including quiet
Contact base, left contact and right contact, the left upper portion of described fixed contact pedestal is provided with the slide opening through fixed contact pedestal, described stationary contact
It is fixed with protruding block, the left side of described left contact is fixed with the litter being inserted in slide opening, described projection inside the left side of headstock
The right-hand member of block is connected with flap, and the upper and lower ends of described flap are connected to left surface and the static contact of left contact respectively by spring
On the inside left face of seat, the bottom of described right contact is run through fixed contact pedestal and is connected with power connection end.
Preferably, it is connected with spring between the right side of described right contact and fixed contact pedestal inner right side face.
Preferably, the right side of described left contact and the left side of right contact are equipped with raised points.
Compared with prior art, the beneficial effects of the utility model are: this static contact passes through joining between flap and spring
Conjunction makes left contact press on contact knife, so that the contact between contact knife and static contact is more closely so that electric conductivity reaches
To optimum efficiency, and in contact knife swapping process, the pressure that left contact is pressed on contact knife can change so that the contact of disconnecting link
Effect is good and is easy to choose.
Brief description
Fig. 1 is this utility model structural representation.
In figure: 1 fixed contact pedestal, 2 left contacts, 3 right contacts, 4 slide openings, 5 protruding blocks, 6 flaps, 7 protruding points, 8
Spring, 9 litter, 10 power connection ends.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, this utility model provides a kind of a kind of technical scheme: static contact of chopper switch, including static contact
Seat 1, left contact 2 and right contact 3, the left upper portion of described fixed contact pedestal 1 is provided with the slide opening 4 through fixed contact pedestal 1, described quiet
It is fixed with protruding block 5, the left side of described left contact 2 is fixed with the litter 9 being inserted in slide opening 4, institute inside the left side of contact base 1
The right-hand member stating protruding block 5 is connected with flap 6, and the upper and lower ends of described flap 6 are connected to a left side for left contact 2 respectively by spring 8
On the inside left face of side and fixed contact pedestal 1, the bottom of described right contact 3 is run through fixed contact pedestal 1 and is connected with power connection end 10.
Further, it is connected with spring 8 between the right side of described right contact 3 and fixed contact pedestal 1 inner right side face, so make
Obtain right contact and be close to contact knife surface under the elastic force of spring, thus increasing electric conductivity.
Further, the right side of described left contact 2 and the left side of right contact 3 are equipped with raised points 7, so so that left
Contact and right contact are close to more firm during contact knife.
Specifically, during use, the contact knife of disconnecting link inserts, when contact knife is contacted with flap 6 between left contact 2 and right contact 3
And during continuing to press downwards, the meeting of flap 6 drives the spring 8 that flap 6 two ends are connected to compress, with the compression of spring 8,
Left contact 2 is moved right along the guiding of slide opening 4 by litter 9, and when left contact 2 touches contact knife, left contact 2 stops fortune
Dynamic, now contact knife continues to pull down flap 6, and spring 8 continues compression storage power, so that left contact 2 is clamped on contact knife, right
Contact 3 can be pressed on contact knife by the spring 8 on the right side of it, power connection end 10 is used for connecting electric power, raised points 7 so that contact knife with
Left contact 2 is more preferably firm with the contact of right contact 3, and then static contact and the electric conductivity of contact knife are reached most preferably；When extracting
During contact knife, spring 8 springing that flap 6 is connected by its bottom rotates to script position, spring 8 meeting that flap 6 top is connected
Left contact 2 is driven to be moved to the left script position, during entirely extracting contact knife, spring 8 acts on the pressure on left contact 2
Taper into, so that the withdrawal process of contact knife becomes easily laborsaving.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with multiple changes in the case of without departing from principle of the present utility model and spirit, repair
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
