Description
Technical field
The present invention relates to capacitor technology field, more particularly to a kind of noinductive capacitor.
Background technology
Capacitor can generate heat at work so that the air pressure increase of confined space in capacitor case, when such as capacitor is long
Between be in the working environment of high temperature, just easily lead to capacitor blast.Existing noinductive capacitor is swollen by internal gas
It is swollen, cause casing deformation bulging, so as to break electrode connecting line, disconnect capacitor, and be unlikely to cause capacitor breakdown or
Short circuit.But this noinductive capacitor is just failed after explosion-proof, it is impossible to voluntarily recover, reuse.
The content of the invention
The problem of for shortcomings and deficiencies in the prior art, the present invention proposes a kind of noinductive capacitor, works as capacitor core
When sub- temperature is too high, disconnection contact and fuse both positive and negative polarity contact are moved up by piston plate, explosion-proof can be played well, and
Capacitor of the present invention can voluntarily recover.
The technical solution adopted for the present invention to solve the technical problems is：
It is fixed in a kind of noinductive capacitor, including metal shell, capacitor body, piston piece and closure, the metal shell
There is dividing plate, piston piece is made up of piston plate and cylinder, hemisphere jut is provided with the middle part of cylinder, cylinder is received through dividing plate middle
Contracting springhole, is fixed with spring between dividing plate and piston plate, the capacitor body is provided with below both positive and negative polarity contact, piston plate
Contact provided with correspondence both positive and negative polarity contact, the closure is provided with binding post, and binding post is electrically connected by wire with contact
Connect.
Further, the cylinder and piston plate are provided with the through hole of conducting wire.
Further, the number of springs is at least two pieces, is distributed on piston plate.
Further, the spring is when contact is normally contacted with capacitor body both positive and negative polarity contact, in not stressing or
Mild compression state.
The present invention has the advantages that：Position-limiting action can be played provided with hemisphere jut in cylinder, to ensure piston piece
It will not easily be stressed and change and move；When capacitor body temperature is too high, piston piece is pushed to top so that capacitor electricity
Pole disconnects, after being cooled down with fuse temperature, and piston piece can help to reset under the elastic force effect of spring, so that capacitor
Can normally it use again.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present invention；
Fig. 2 is that capacitor body disconnects working state schematic representation.
Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
As illustrated, a kind of noinductive capacitor, including metal shell 1, capacitor body 2, piston piece 3 and closure 4, institute
State and dividing plate 11 is fixed with metal shell 1, piston piece 3 is made up of piston plate 21 and cylinder 22, the middle part of cylinder 22 is provided with spherical male
101 are played, cylinder 22 passes through the collapsible springhole of the middle of dividing plate 11, and spring 31 is fixed between dividing plate 11 and piston plate 21,
The capacitor body 2 is provided with both positive and negative polarity contact 41, contact 42 of the lower section of piston plate 21 provided with correspondence both positive and negative polarity contact 41, institute
Closure 4 is stated provided with binding post 51, binding post 51 is electrically connected by wire 52 with contact 42.
The cylinder 22 and piston plate 21 are provided with the through hole of conducting wire 52.
The quantity of spring 31 is at least two pieces, is distributed on 21 on piston plate.When contact 42 and the both positive and negative polarity of capacitor body 2
When contact 41 is normally contacted, spring 31 is in and not stressed or mild compression state.
Specifically, during capacitor normal work, the contact 42 of piston piece 3 connects with the both positive and negative polarity contact 41 on capacitor body 2
Touch, the hemisphere jut 101 on cylinder 22 plays position-limiting action.As the capacitor working time is long, the temperature of capacitor body 2 by
Edge up height, and the air pressure in the lower section chamber of piston piece 3 also gradually increases so that piston plate 21 is by upward thrust.When thrust increase
During to critical value, piston plate 21 overcomes the elastic force of spring 31 to move up, and the hemisphere jut 101 of cylinder 22 breaks through the bullet on dividing plate 11
Property hole is moved up therewith.Now the contact 42 on piston plate 21 departs from the both positive and negative polarity contact 41 on capacitor body 2, and capacitor is just
Do not work, cause capacitor body 2 to occur aging or punch-through so as to avoid too high temperature, serve explosion-proof effect
Really.
After being stopped with capacitor, capacitor body 2 is begun to cool down, when the lower section air pressure of piston plate 21 is reduced to necessarily
During value, piston plate 21 is under the elastic force effect of spring 31 so that the hemisphere jut 101 of cylinder 22 overcomes springhole on dividing plate 11
Spacing, piston piece 3 is moved down so that contact 42 is contacted again with the both positive and negative polarity contact 41 on capacitor body 2, is recovering capacitor just
Normal working condition.
