Abstract
The utility model relates to a low-voltage switch electrical product-magnetic latching relay, the technical proposal mainly utilizes a yoke iron with a U-shaped structure, a permanent magnet arranged at the middle part of the yoke iron and an armature iron matched with a lever structure to form a magnetic loop of double-loop alternative magnetic conduction work to realize a bistable state working form. The technology has the characteristics of small driving power, large braking load capacity, high sensitivity, simple design of a driving circuit, wide application field and strong structural integrity.
Description
Technical field
The utility model relates to the low-tension switch electric appliance product with bistable operation mode---electromagnetism magnetic latching relay.
Background technology
Existing magnetic latching relay product also is not quite similar according to its structure construction of different design principles.Wherein a class is the relay product that remanent magnetism keeps function, the defective of this product is the fearness vibrations, the retention time is short, the braking contact capacity is limited: another kind of is monocoil magnetic latching relay, this relay need be provided with the drive circuit that changes driving voltage polarity, its configuration is comparatively loaded down with trivial details, responsiveness is also slower, long-time running also occurs magnetic easily and declines, and is difficult for the jumbo change over contact of braking; Also having a series products structure is that solenoid is provided with a centre cap as common pole, the pulse input circuit is set respectively makes it produce adhesive, disjunction braking maneuver.Also the ubiquity small product size is big, driving power consumption is big, action sensitivity is low, the low technological deficiency of structural entity degree of product for existing youngster's class relay product.So existing magnetic latching relay product technology is also imperfect.
The utility model content
The drive circuit that for a change existing magnetic latching relay product exists is comparatively complicated, the state of the art that needs bigger driving power, the utility model provides the technical scheme of a cover bistable magnetic latching relay, the major technique content of this technical scheme is: this bistable magnetic latching relay includes housing, be assembled in electromagnetic circuit part and switch contact part in the housing, the yoke of its electromagnetic circuit part is the U type frame-type yoke of single-ended opening, be wound with separate coil respectively on the two yoke frameworks of formation opening, on the yoke between two solenoids, fix a permanent magnet to yoke open side vertical extent, be arranged at the yoke opening part, contact with permanent magnet top magnetic and to be provided with a lever armature, this armature is with the balance pivot of its permanent magnet contact point as this lever, its both sides respectively with the end face adhesive of yoke framework or bullet from, the fixed contact of switch contact part is arranged at an end place of armature, with the moving contact switch configuration of armature.
In the disclosed bistable magnetic latching relay of the utility model technical scheme, its switch contact partial design has adopted the armature mechanism of lever actuated, electromagnetic circuit with matching portion adopted can two coiling independence solenoids U type yoke, and permanent magnet is set in the middle part of U type yoke to improve the reliability of switch contact, constituted jointly and be alternately closed, the double loop magnetic pumping passage of disjunction, realized driving the purpose of design of big capacity load with little driving power signal, it has the rapid and fireballing characteristics of action response of braking, and can design one or more groups change over contact structure neatly, and split type loop construction has been simplified design of drive circuit, can cooperate and adopt multiple driving pulse circuit, replace the continuous impulse circuit as two-way, single channel intermittent pulse input circuit, the input of single channel voltage, single channel voltage input time delay circuit etc., thereby make this product have more various design form and application fields, this product structure globality is strong, magnetic loss is little, also has the characteristics of long service life.
Description of drawings
What accompanying drawing provided is the part sectional structure schematic diagram of this bistable magnetic latching relay.
Embodiment
Bistable magnetic latching relay of the present utility model includes the electromagnetic circuit part and the switch contact that are assembled in the plastic capsule 1 and partly constitutes, the structure of its electromagnetic circuit part is formed: yoke 6 is the U type frame-type yoke of single-ended opening, be wound with separate coil 71 respectively on the two yoke frameworks 60 of formation opening, 72, two solenoids 71, on the yoke 61 between 72, fix a permanent magnet 5 to yoke open side vertical extent, in the present embodiment, capsule 1 has only formed the closed housing that passes for yoke end face separately respectively on two coils, permanent magnet 5 is plugged in the space between two closed housings, the open side that is positioned at yoke 6 contacts with permanent magnet 5 top magnetic and is provided with a lever armature 4, this armature 4 is with the balance pivot of its permanent magnet contact point 8 as this lever, its both sides respectively with the end face adhesive of yoke framework 60 or bullet from, for further prolonging the development length of permanent magnet 5, the top of permanent magnet 5 is provided with parallels 9 and balance pivot mechanism, make this armature 4 form T word shape structure: the fixed contact 2 of the switch contact part of this relay is arranged at an end position of armature 6, and the armature of this end is provided with the sound point 3 that cooperates with fixed contact 2 switches.
The course of work of this bistable magnetic latching relay is such: output drive voltage signal in one lateral coil loop, the electromagnetic field that it produced and the magnetic field of permanent magnet are synthetic to strengthen, this side of inhaling moving armature 4 moves down, drive its contact mechanism adhesive, driving voltage in this coil was disappeared, and armature 4 also can keep the sticking state reliably under the action of a magnetic field of permanent magnet 5; In like manner, if driving pulse voltage comes across in the wire loop of opposite side, then armature 4 is reversed adhesive, and its adhesive side is drawn back, disjunction, has promptly formed the bistable operation braking course of work.
