Abstract
The utility model discloses a kind of magnetic latching relay adopting flexible quiet spring, comprise flexible quiet spring, fixed contact and pedestal; Described fixed contact is fixed on flexible quiet spring, and the root of flexible quiet spring is inserted on pedestal; Described pedestal is provided with for stopping the stop block of flexible quiet spring to the movement of moving contact direction corresponding to above described fixed contact.The utility model, by the improvement to the position limiting structure of the quiet spring of flexibility, can reach good limit effect, to strengthen the breaking capacity of sound contact; To greatest extent for sound contact provides good arcing environment, secondary arcing probability can be reduced, thus greatly reduces product failure risk again.
Description
Technical field
The utility model relates to relay technical field, particularly relates to a kind of magnetic latching relay adopting flexible quiet spring.
Background technology
Magnetic latching relay is made up of magnetic circuit system, contact system, pushing portion and pedestal, wherein magnetic circuit system is generally made up of magnetic circuit part and armature part, contact system is then made up of dynamic spring part and quiet spring part, and the quiet spring part of the magnetic latching relay of the flexible quiet spring of this employing is then made up of the quiet spring of flexibility and fixed contact.In the magnetic latching relay adopting flexible quiet spring, due to the existence of the quiet spring of flexibility, relay can stably produce the high overtravel of consistency in connection process, be conducive to the consistency and the stability that improve product parameters, simultaneously in the process of the closing of contact due to the generation displacement of quiet spring, make the mutual rubbing in sound contact, the effect of anti-adhesive can be produced.Exactly because but the existence of also flexible quiet spring, relay contact system is in disconnection process, and the ability that flexible quiet spring opposing contact is bonding, easily causes the failure mode broken not open in contact.Therefore, the position limiting structure performance on relay of flexible quiet spring in relay disconnection process has vital impact.
The magnetic latching relay of the flexible quiet spring of existing employing is typically provided with the position limiting structure to the quiet spring of flexibility, Fig. 1 is the structural representation of the magnetic latching relay of the flexible quiet spring of employing of prior art, as shown in Figure 1, this magnetic latching relay comprises flexible quiet spring 100, fixed contact 101 and pedestal 102, flexible quiet spring 100 is contained on pedestal 102, pedestal 102 is provided with the positive stop 103 to the quiet spring of flexibility, positive stop 103 is located at below fixed contact 101, this structure can prevent sound contact bonding in relay disconnection process to a certain extent, but also there is inevitable shortcoming: this positive stop 103 be located at below fixed contact 101, positive stop 103 from fixed contact 101 more close to, its limit effect is better, but positive stop 103 is plastic construction, plastic construction is the closer to contact 101, arcing environment after contact disconnects is poorer, easy formation carbon distribution causes relay not conducting or causes puncturing thus the repeatedly phenomenon such as starting the arc between sound contact, substantially increase the risk that relay not conducting was lost efficacy or punctured inefficacy.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art, provides a kind of magnetic latching relay adopting flexible quiet spring, by the improvement of the position limiting structure to the quiet spring of flexibility, can reach good limit effect, to strengthen the breaking capacity of sound contact; To greatest extent for sound contact provides good arcing environment, secondary arcing probability can be reduced, thus greatly reduces product failure risk again.
The utility model solves the technical scheme that its technical problem adopts: a kind of magnetic latching relay adopting flexible quiet spring, comprises flexible quiet spring, fixed contact and pedestal; Described fixed contact is fixed on flexible quiet spring, and the root of flexible quiet spring is inserted on pedestal; Described pedestal is provided with for stopping the stop block of flexible quiet spring to the movement of moving contact direction corresponding to above described fixed contact.
Further, the stop block of described pedestal is located at above the side corresponding to described fixed contact, and the quiet spring of described flexibility is laterally provided with protuberance to be used for and described stop block corresponding matching.
Described stop block is the rectangular limited post of pedestal sidewall along the length direction horizontal-extending of pedestal, and the protuberance of the quiet spring of described flexibility is the elongated rectangular configuration of top along the Width horizontal-extending of pedestal of flexible quiet spring.
A kind of magnetic latching relay adopting flexible quiet spring of the present utility model, be provided with for stopping the stop block of flexible quiet spring to the movement of moving contact direction above the side corresponding to described fixed contact of pedestal, the quiet spring of flexibility is then laterally provided with protuberance to be used for and described stop block corresponding matching, this position limiting structure, good limit effect can be reached, to strengthen the breaking capacity of sound contact; To greatest extent for sound contact provides good arcing environment, product arc extinction performance can be improved again, thus greatly reduce product failure risk.
The beneficial effects of the utility model are:
Be provided with for stopping the stop block of flexible quiet spring to the movement of moving contact direction owing to have employed above the side corresponding to described fixed contact of pedestal, the quiet spring of flexibility is then laterally provided with protuberance, realize carrying out spacing above contact to the quiet spring of flexibility with coordinating of protuberance by stop block, this position limiting structure, on the one hand, away from sound contact, can to greatest extent for sound contact provides good arcing environment, reduce secondary arcing probability, greatly reduce product failure risk; On the other hand, because position limiting structure is above the side of sound contact, and flexible quiet spring is designed to elongated rectangular configuration, twisting actions can be produced in sound contact disconnection process, thus make to produce between sound contact vertically with the relative rolling in horizontal both direction, play the effect of enhancing sound contact breaking capacity.
Below in conjunction with drawings and Examples, the utility model is described in further detail; But a kind of magnetic latching relay of flexible quiet spring that adopts of the present utility model is not limited to embodiment.
