Description
Technical field
The utility model is related to a kind of relay in low-voltage electrical field more particularly to a kind of the high-power of adjusting zero of knock-oning
Magnetic latching relay structure.
Background technology
Magnetic latching relay has been developed in recent years a kind of new type of relay, due to the contact shape of magnetic latching relay
State is kept by the magnetic force of permanent-magnet steel, therefore, when control contact is converted, only need to input the forward direction of one fixed width at coil both ends
Or reversed DC pulse can realize the connection and cut-out of magnetic latching relay.
In the prior art, magnetic latching relay mainly include coil block, lever assembly, console panel, movable spring assembly and
Quiet spring component promotes to have the lever assembly of permanent-magnet steel to rotate by the DC pulse being applied on coil block, and by grasping
Vertical pole component drives console panel movement, so that console panel pushes movable spring assembly to act and makes movable contact thereon and quiet spring group
Stationary contact on part is closed, on the contrary then disconnect.However, can not be solved since quiet spring component in the prior art always exists one
The problem of：Exactly if to realize the high current of magnetic latching relay, powerful use, it must be promoted and be made on quiet spring component
It is for the thickness of the conductive component of current-carrying part, but when the thickness of conductive component is increased, then corresponding to reduce conductive part
The elasticity of part, and then lead to not buffer movable contact and impact force caused by stationary contact closure moment, it is easy to damage dynamic touch
Point or stationary contact, therefore, what magnetic latching relay in the prior art used is all relatively thin conductive component, i.e., elastic spring
Piece so that partially effective buffering can be obtained (although being yet not achieved complete in impact force when movable contact is closed with stationary contact
Buffering), however this structure also limits the high current of magnetic latching relay, powerful use (because of elastic spring simultaneously
Insufficient load current to support high current, powerful use), at the same time, in the prior art, when dynamic on movable spring assembly touches
Point since the impact force that quiet spring component is subject to can only obtain buffering for part, and then causes to close with stationary contact point touch and when being closed
The moment contact of conjunction generates shake, that is, the rebound that those skilled in the art often say, and then strong influence magnetic keeps relay
The reliability and stability of device performance, also influence service life；In market when the rebound of existing magnetic latching relay
Between it is general all more than hundreds of milliseconds, magnetic latching relay use of this quality is wanted to knock-oning intelligent capacitor etc. is certain
High application field is sought, it is not satisfactory.
Invention content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of simple in structure, reliable working performance
Stablize and can effectively improve the power magnetic force keeping relay structure of the rebound adjusting zero of service life.
To achieve the above object, the utility model uses a kind of power magnetic force keeping relay structure of rebound adjusting zero,
Including cover board, pedestal and the coil block being set on pedestal, lever assembly, console panel, movable spring assembly and static contact panel, institute
The movable contact that movable spring assembly has movable contact spring and is arranged on movable contact spring is stated, is had on the static contact panel opposite with the movable contact
The stationary contact that should be arranged, the lever assembly are formed forward and reverse by the positive and negative pulse signal that the coil block transmits
Rotation, the console panel are formed with the lever assembly and are linked, and the movable spring assembly is formed with the console panel and linked, described
On pedestal, the side that leans against static contact panel be provided with elastic endergonic piece, the elastic endergonic on piece is threaded with adjusting screw, institute
The top for stating adjusting screw is connected on the static contact panel.
By the above-mentioned improvement to the prior art, since quiet spring component in the prior art directly being substituted with static contact panel,
Therefore, the static contact panel that the magnetic latching relay of the utility model can configure any thickness as needed is realized as current-carrying part
High current and powerful use environment simultaneously as being provided with elastic endergonic piece at the rear of static contact panel, and are inhaled in elasticity
Energy piece and static contact panel are provided directly with adjusting screw, when the stationary contact on the movable contact and static contact panel on movable spring assembly is closed,
Impact force caused by its moment passes to elastic endergonic piece by static contact panel via adjusting screw so that static contact panel not by
The influence of impact force and can work normally；In addition, due to directly using static contact panel, avoid in the prior art because using elastic spring
Piece and the problem of cannot achieve the high current of magnetic latching relay, high-power applications；Finally, above-mentioned static contact panel and elastic endergonic piece
And the structure setting of adjusting screw, when the movable contact on movable spring assembly is deviated the impact force of static contact panel with predetermined value
When, it can realize fine tuning by way of to the small precession of adjusting screw or small back-out, and then truly realize magnetic
Zero rebound performance of guard relay, is greatly improved the job stability of magnetic latching relay, improves service life.
As the further setting of the utility model, to effectively prevent the abutted position of static contact panel and adjusting screw impacting
Deviated under the action of power, cause error, on the static contact panel, position corresponding with the adjusting screw have position it is recessed
Slot, the adjusting screw are connected in the positioning groove.
As the further setting of the utility model, adjusting screw is finely adjusted for convenience, on the pedestal, with
Adjustment hole is offered on the corresponding side wall of nut portion of the adjusting screw.
As the further setting of the utility model, longitudinal direction is formed on the pedestal, close to the position of the adjustment hole
Slot, on the cover board, described in position corresponding with the longitudinal socket forms and be adapted to the longitudinal socket and be enough to cover
Longitudinal plate of adjustment hole；The setting of such structure so that magnetic latching relay after the completion of assembly, as finished product in use,
Limit other people by adjustment hole carry out it is arbitrary adjusting (when needing to be finely adjusted magnetic latching relay, then must first tear open
Fall cover board, can be adjusted), as well as the effect of blocking of longitudinal plate, avoids electric current and climbed outward by adjustment hole
Electricity improves the insulation protection of magnetic latching relay.
