Abstract
Aiming at arc and spark problems of a circuit breaker, the invention provides a circuit breaker structure. The structure comprises a pedestal, an elastomer, a static contact, a moving contact and an arc extinguisher. The elastomer is installed on the pedestal. The static contact is installed on the elastomer. A front end of the moving contact is in an arc shape. And the moving contact is connected to the static contact. An arc extinguisher is installed on a periphery of a connection portion of the moving contact and the static contact. In the invention, the front end of the moving contact is in the arc shape so that a possibility of point discharge is reduced; when a circuit is disconnected, under cooperation of the elastomer, the circuit is slowly disconnected and an arc or spark generated occasionally is extinguished rapidly by the arc extinguisher so that a condition that the circuit breaker generates the arc or the spark when closing or disconnecting a current can be effectively prevented.
Description
Technical field
The present invention relates to field of circuit breakers, refer more particularly to a kind of breaker structure.
Background technology
In all kinds of electric equipments, it is required for using chopper.Chopper closed and disconnected electric current time
Wait, due to the effect of moment, easily produce electric arc, spark, bring danger to the use of instrument and equipment.
Summary of the invention
For electric arc and the problem of spark of chopper, the present invention provides a kind of breaker structure, it is possible to have
The chopper that prevents of effect produces electric arc or spark closed and disconnected electric current when.The present invention is taked
Technical scheme be, a kind of breaker structure, including pedestal, elastomer, static contact, moving contact, go out
Arc device, wherein, elastomer is arranged on pedestal, and static contact is arranged on elastomer, the front end of moving contact
For arc-shaped, and moving contact is connected with static contact；The surrounding that moving contact and static contact connect is provided with goes out
Arc device.
The front end of the moving contact of the present invention is arc-shaped, reduces the possibility of point discharge.At disconnecting circuit
Time, under the cooperation of elastomer, circuit is slowly to disconnect, and the electric arc or the spark that produce once in a while also can
Sopped up rapidly by extinguisher, it is possible to effectively prevent chopper from producing electricity closed and disconnected electric current when
Arc or spark.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1 pedestal, 2 elastomers, 3 static contacts, 4 moving contacts, 5 extinguishers.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
Fig. 1 is the structural representation of the present invention, pedestal 1, elastomer 2, static contact 3, moving contact 4, arc extinguishing
Device 5, wherein, elastomer 2 is arranged on pedestal 1, and static contact 3 is arranged on elastomer 2, moving contact 4
Front end is arc-shaped, and moving contact 4 is connected with static contact 3；Moving contact 4 and static contact 3 connect around
Extinguisher 5 is installed.The front end of the moving contact 4 of the present invention is arc-shaped, reduces the possibility of point discharge.
When disconnecting circuit, under the cooperation of elastomer 2, circuit is slowly to disconnect, the electric arc that produces once in a while or
Person's spark also can be sopped up rapidly by extinguisher 5, it is possible to effectively prevents chopper at closed and disconnected electric current
Time produce electric arc or spark.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, the present invention is not restricted to the described embodiments, above-described embodiment and explanation
The principle that the present invention is simply described described in book, without departing from the spirit and scope of the present invention,
The present invention also has various changes and modifications, and these changes and improvements both fall within claimed invention model
In enclosing.Claimed scope is defined by appending claims and equivalent thereof.
