Description
Technical field
The present invention relates to relay technical fields, more particularly to a kind of magnetic latching relay using flexible quiet spring.
Background technique
Magnetic latching relay by magnetic circuit system, contact system, part is pushed to form with pedestal, wherein magnetic circuit system generally by
Magnetic circuit part and armature part composition, contact system are then made of dynamic spring part and quiet spring part, this flexible quiet spring of use
The quiet spring part of magnetic latching relay is then made of flexible quiet spring and stationary contact.In the magnetic latching relay using flexible quiet spring
In, due to the presence of flexible quiet spring, relay can steadily generate consistency high overtravel during connection, be conducive to
The consistency and stability of product parameters are improved, while making sound since the generation of quiet spring is displaced during contact closure
The mutual rubbing in contact, can produce the effect of anti-adhesive.Exactly because but also the presence of flexible quiet spring, relay contact system exist
In disconnection process, the ability that flexible quiet spring resists contact bonding is poor, the failure mode for be easy to causeing contact to break not open.Therefore, soft
Position limiting structure of the quiet spring of property in relay disconnection process has vital influence to the performance of relay.
The existing magnetic latching relay using flexible quiet spring is typically provided with the position limiting structure to flexible quiet spring, and Fig. 1 is existing
The structural schematic diagram of the magnetic latching relay using flexible quiet spring of technology, as shown in Figure 1, the magnetic latching relay includes flexibility
Quiet spring 100, stationary contact 101 and pedestal 102, for flexible quiet spring 100 on pedestal 102, pedestal 102 is equipped with the limit to flexible quiet spring
Position block 103, limited block 103 are located at 101 lower section of stationary contact, this structure can prevent to a certain extent sound contact in relay
It is bonded in device disconnection process, but there is also inevitable disadvantages: this limited block 103 for being located at 101 lower section of stationary contact, limit
Position block 103 is closer from stationary contact 101, and limit effect is better, but limited block 103 is plastic construction, and plastic construction is got over
Close to contact 101, the arcing environment after contact disconnects is poorer, and carbon distribution easy to form causes relay to be not turned on or cause sound
Phenomena such as breakdown between contact is to the multiple starting the arc substantially increases the risk that relay is not turned on failure or breakdown failure.
Summary of the invention
It is an object of the invention to overcome the deficiency of the prior art, provides a kind of magnetic holding relay using flexible quiet spring
Device can reach preferable limit effect, by the improvement of the position limiting structure to flexible quiet spring to enhance the disjunction of sound contact
Ability；Good arcing environment can be provided for sound contact to the maximum extent again, secondary arcing probability be reduced, to substantially reduce
Product failure risk.
The technical solution adopted by the present invention to solve the technical problems is: a kind of magnetic holding relay using flexible quiet spring
Device, including flexible quiet spring, stationary contact and pedestal；The stationary contact is fixed on flexible quiet spring, and the root of flexible quiet spring is inserted into
On pedestal；The pedestal is equipped in the top for corresponding to the stationary contact is used to stop flexible quiet spring to the movement of movable contact direction
Stop block.
Further, the stop block of the pedestal is located at the upper side corresponding to the stationary contact, the quiet spring edge of flexibility
It is equipped with protrusion laterally to be used to and the stop block corresponding matching.
The stop block is length direction horizontal-extending strip limited post of the pedestal side wall along pedestal, and the flexibility is quiet
The protrusion of spring is the top of flexible quiet spring along the horizontal-extending elongated rectangular configuration of width direction of pedestal.
A kind of magnetic latching relay using flexible quiet spring of the invention, is in the side corresponding to the stationary contact of pedestal
The stop block that top is equipped with for stopping flexible quiet spring mobile to movable contact direction, then along laterally equipped with protrusion on flexible quiet spring
Be used to the stop block corresponding matching, this position limiting structure can reach preferable limit effect, to enhance sound contact
Breaking capacity；Good arcing environment can be provided for sound contact to the maximum extent again, product arc extinction performance be improved, thus greatly
It is big to reduce product failure risk.
The beneficial effects of the present invention are:
It is used to stop flexible quiet spring to dynamic touching due to being equipped with using the upper side corresponding to the stationary contact in pedestal
The mobile stop block in point direction, then along protrusion is laterally equipped on flexible quiet spring, the cooperation for passing through stop block and protrusion is realized pair
Flexible quiet spring is limited above contact, this position limiting structure, on the one hand, far from sound contact, can be to the maximum extent
Sound contact provides good arcing environment, reduces secondary arcing probability, substantially reduces product failure risk；On the other hand, by
In upper side of the position limiting structure in sound contact, and flexible quiet spring is designed as elongated rectangular configuration, can be disconnected in sound contact
Twisting actions are generated in open procedure, to generate between making sound contact vertically with the relative rolling in horizontal both direction, are played
Enhance the effect of sound contact breaking capacity.
Invention is further described in detail with reference to the accompanying drawings and embodiments；But of the invention is a kind of using flexible quiet
The magnetic latching relay of spring is not limited to the embodiment.
