Abstract
The invention discloses a kind of breaker, including housing, operation handle, the lever piece being engaged with the operation handle, it can coordinate to contradict with the lever piece and to prevent from turning on lever piece hit locating part, moving contact, static contact, magnetictrip and the arc-chutes of handle, the moving contact is electrically connected with the magnetictrip；It is articulated with the middle part of the lever piece on the housing；When the operation handle acts in the counterclockwise direction, one end that the lever piece can be driven to be matched therewith is stirred downwards to drive the moving contact to be moved to the position contacted with the static contact；When the operation handle acts along clockwise direction, one end that the lever piece can be driven to be matched therewith is stirred to drive the moving contact to be moved to the position being separated with the static contact upwards.The present invention is simple in construction, and being driven moving contact by lever piece acts, and Stability Analysis of Structures, is hardly damaged.
Description
Technical field
The invention belongs to breaker technical field, more particularly, to a kind of breaker.
Background technology
Breaker is a kind of electric current that can be closed, carry and cut-off under normal loop condition, and can be in the defined time
Interior carrying and the switching device for cut-offfing the electric current under abnormal loop condition.Existing breaker typically matching somebody with somebody by handle and lever
The contact or separation between dynamic/static contact are realized in conjunction.But existing breaker essentially closes a floodgate clockwise, opens a sluice gate counterclockwise
Structure setting, under this kind of special construction, the angle between U-shaped bolt and lever between operation handle and lever need to be arranged to sharp
Angle, slowly change to obtuse angle to act driving moving contact movement in making process with activation lever.But the relay of this kind of structure
Device, during lever carries out backhaul, lever is larger for the shock dynamics of tripping, is also damaged after long-term use of.
The content of the invention
The present invention is for overcome the deficiencies in the prior art, there is provided a kind of breaker of service life length.
To achieve these goals, the present invention uses following technical scheme：A kind of breaker, it is disconnected the invention discloses one kind
Road device, including housing, operation handle, the lever piece being engaged with the operation handle, can with the lever piece coordinate contradict to prevent
Only turned on lever piece and hit locating part, moving contact, static contact, magnetictrip and the arc-chutes of handle, the moving contact with
The magnetictrip is electrically connected；It is articulated with the middle part of the lever piece on the housing；The operation handle is in the counterclockwise direction
During action, one end that the lever piece can be driven to be matched therewith stir downwards with drive the moving contact be moved to it is described quiet
The position of contact；When the operation handle acts along clockwise direction, can drive that the lever piece is matched therewith one
Stir upwards to drive the moving contact to be moved to the position being separated with the static contact at end.The present invention is simple in construction, due to
Handle operates the change in direction so that the angle between U-shaped bolt and lever is changed into obtuse angle, all the time in tight between lever and handle
Pressure condition so that lever is not in the situation for moment hitting keeper during being reset to and opening a sluice gate by combined floodgate, both it
Between be not easy damage because of hitting, the service life of equipment is grown；Acted secondly by lever piece transmission moving contact, structure is steady
It is fixed, it is hardly damaged；There is provided locating part, the recovery stroke of lever piece can be limited by locating part, prevent lever piece with
Handle hits, and both are not susceptible to damage；It can also prevent lever recovery stroke excessive simultaneously and cause moving contact and other
Electrical part collides, and extends the service life of moving contact.
Further, one end of the lever piece is connected by a connection piece with the operation handle, the lever piece
The other end is engaged with the moving contact.
Further, the lever piece has the connection end being connected with connector, and the connection end is located at orientation under handle
Put, there is gap between the connection end and the operation handle；So that Relative friction will not occur between lever and operation handle,
It will not wear, increase the service life between the two.
Further, the connector is connecting rod, and the angle between the connecting rod and the lever piece is obtuse angle；Ensure lever
It is in compaction all the time between handle so that lever is not in hit moment during being reset to and opening a sluice gate by combined floodgate
The situation of keeper is hit, is not easy to damage because of hitting between the two, the service life length of equipment.
Further, the moving contact is connected by a linking arm with the lever piece, and one and institute are provided with the housing
Linking arm is stated to be engaged to limit the keeper of the running orbit of the moving contact；Moving contact can be limited and enter water-filling in left-right direction
Translation is dynamic and then is in contact with static contact, for comparing moving contact by overturning situation about being contacted with static contact, between the two
Shock dynamics it is smaller, dynamic/static contact is not susceptible to damage.
Further, the linking arm and moving contact are electrically connected by copper conductor and the magnetictrip respectively.
Further, the keeper includes the body of rod being arranged in the linking arm, and the linking arm can be along the bar
Body moves forward and backward；Moving contact can be limited to be moved horizontally and then be in contact with static contact in left-right direction, compare moving contact
For overturning situation about being contacted with static contact, shock dynamics between the two is smaller, and dynamic/static contact is not susceptible to damage.
Further, described body of rod one end is connected with the magnetictrip, and the other end passes through the linking arm；Ensure to connect
Connecing arm can be moved forward and backward along the body of rod length direction, and track deviation will not occur.
Further, the locating part includes tripping part and snap close piece, and the tripping part is provided with can be with the lever piece
Coordinate the extension contradicted, the snap close piece is provided with the bayonet socket being engaged with the extension；Pass through extension and bayonet socket
Coordinate, the recovery stroke of lever piece is carried out spacing, prevent from climbing over head on lever and make it that moving contact is moved through multiposition, move tactile
With other electrical parts unnecessary collision will not occur for head.
In summary, the present invention has advantages below：Simple in construction, the mode of operation of handle control switching is ingenious, real
It is existing to be in compaction between lever and handle all the time, prevent keeper from excessively being hit with lever piece, extend both uses the longevity
Life length.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
In order that those skilled in the art are better understood from the present invention program, below in conjunction with the embodiment of the present invention
Accompanying drawing, clear, complete description is carried out to the technical scheme in the embodiment of the present invention.
As shown in figure 1, a kind of breaker, including housing 1, operation handle 2, the lever piece 3 being engaged with the operation handle,
It can coordinate to contradict with the lever piece and hit the locating part 4, moving contact 5 and static contact 6 of handle to prevent from turning on lever piece；Institute
The middle part for stating lever piece 3 is articulated with the housing, and one end of lever piece 3 passes through a connection piece 7 and the phase of operation handle 2
