Description
Technical field
The utility model relates to a kind of automatic control apparatus element, particularly a kind of magnetic latching relay with memory function.
Background technology
Magnetic latching relay is a kind of new type of relay that grew up in recent years, also is a kind of automatic switch.The same with other electromagnetic relays, circuit is played automatic connection and cutting action.Different is, the normally closed or normally open of magnetic latching relay is the effect that relies on permanent-magnet steel fully, and the conversion of its on off state triggers by the pulse electrical signal of certain width and finishes.
Magnetic latching relay is to be mainly used in IC-card pre-paying kilowatt-hour meter, the automatic meter reading system the earliest.Recent years, magnetic latching relay is applied in the combination switch of reactive power compensator in large quantities, in combination switch, be used with controllable silicon, become the main switching device in the reactive power compensator, with the usefulness of switching high-current circuit, in also available various household electrical appliances and the automatic control equipment (as lamp light control system).Be particularly suitable for still need remaining on for a long time behind the connection circuit in the device occasion of switching state.Maintain previous status after using this kind relay can guarantee to switch and coil no longer needs to apply electric energy, thereby reached energy-saving effect.
Existing magnetic latching relay comprises magnetic circuit system and contact system.The rotation of the medium and small axle of magnetic circuit system is to rely on support to come balance and stability, and this structure is symmetrical cross connection type location, requires accessory size symmetry precision height, and it is many to influence the stable constraints of rotating shaft.And those part processing precisions are difficult to guarantee.The magnetic force fine setting of magnetic system is the adjustment that reaches electric parameter with the insulating bar that the combination of compressing magnet steel is stretched out.This direct mode that is adjusted into easily produces the difficult technical problem of magnetic force adjustment control, thereby has influenced production efficiency.
The utility model content
The purpose of this utility model is to provide a kind of magnetic latching relay, requires accessory size symmetry precision height to solve in the prior art, and it is many to influence the stable constraints of rotating shaft, and those part processing precisions technical problem of being difficult to guarantee.
In order to achieve the above object, the utility model provides a kind of magnetic latching relay, it comprises the housing parts of being made up of shell and cover plate, coil combination, contact system and magnet steel combination, it also comprises spacer and card, the card side is located in this shell, first draw-in groove and second draw-in groove are set on it, the magnet steel built-up shaft of this magnet steel combination passes this first draw-in groove and protrudes out the hole slot that is arranged on this shell, the top of the moving contacting plate of contact system is arranged in this second draw-in groove, this magnet steel built-up shaft slides in this hole slot, drive this moving contacting plate motion, so that the quiet contact chip of moving contacting plate and contact system contacts or disconnects, spacer is arranged on this magnet steel built-up shaft, the little axle alignment of its little axis hole and magnet steel combination.
Between inherent moving contacting plate of shell and the magnet steel combination dividing plate is set, this spacer is provided with a medial launder, circular hole and both sides square hole, this medial launder is plugged on this dividing plate, and this circular hole is plugged in the raised points of magnet steel built-up shaft, and this both sides square hole is plugged on the boss of yoke of magnet steel combination.
Also be provided with on this moving contacting plate on first draw-in groove that auxiliary pressurization moving plate states pushing piece and second draw-in groove and be provided with one in order to come together to carry out the side boss that magnetic force is finely tuned with auxiliary pressurization moving plate.
On these shell four sides groove is set respectively, on these cover plate four sides raised line is set respectively, this groove and this raised line are formed internal fastening type mechanism.
The utility model is that the little shaft support of magnet system is modified into the spacer form.On the pedestal of shell, increase the dividing plate of spacer.Little axis hole behind the spacer insertion dividing plate on the spacer aligns with the little axle of magnetic system, has reduced constraints, has reached little axle and can rotate flexibly in the film perforation of location.The utility model is to increase by a boss on card, when magnetic force is adjusted, adjusts indirectly by the push card boss and can reach the fine setting purpose, has guaranteed stablizing of electric parameter.Shell, the internal fastening type structure is adopted in the cooperation of cover plate, and this structure has the comfortable outward appearance and the appearance of polishing.Change by to existing magnetic latching relay design of part makes part processing simple, and device is adjusted simple, parameter stability, and properties of product can be improved.
