Description
Technical field
The present invention relates to a kind of relay and move spring, particularly but be not limited to a kind of magnetic latching relay and move spring group, belong to parts of relay.
Background technology
Because magnetic latching relay is energized work unlike common relay always, the tracking (overtravel) of contact is long less than common relay, makes magnetic latching relay not have common relay reliable in action.
The description of the invention of Authorization Notice No. CN202352589U discloses a kind of magnetic latching relay and moves spring pack, be made up of dynamic spring main leaf, the dynamic large curved supporting spring of spring, the dynamic little curved supporting spring of spring, movable contact, dynamic spring main leaf, the dynamic little curved supporting spring of spring, the dynamic large curved supporting spring of spring compact siro spinning technology successively from top to bottom, movable contact is arranged on the below of dynamic spring main leaf, it is characterized in that: the edge of described dynamic spring main leaf is provided with pressure contact and contacts contact.Although this magnetic latching relay moves, spring pack is not yielding, contact is good, and its overtravel is short, makes relay unreliable.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, and provide a kind of reasonable in design, overtravel is long, safe and reliable, and structure is simple, and the magnetic latching relay of long service life moves spring group.
The present invention's adopted technical scheme that solves the problem is: this magnetic latching relay moves spring group, comprise dynamic spring main leaf, the dynamic large curved supporting spring of spring, the dynamic little curved supporting spring of spring and movable contact, described dynamic spring main leaf, the dynamic little curved supporting spring of spring, the dynamic large curved supporting spring of spring compact siro spinning technology successively from top to bottom, it is characterized in that: described dynamic spring main leaf is provided with bending groove, dynamic spring main leaf is separated into lamellar body and bending sheet by described bending groove, and described bending sheet up bends.Can solve like this due to movable contact and stationary contact work long hours time, contact is made after contact material evaporation, reduce the pressure between movable contact and stationary contact, movable contact even can be made not contact with stationary contact, so increase the service life that contact overtravel effectively can improve relay.Curved on bending sheet, bending sheet is not directly contacted with the little curved supporting spring of dynamic spring being positioned at dynamic spring main leaf bottom, effectively can reduce magnetic latching relay like this, at load operation back contact material, transfer projection occur, increase the thick of two contacts, the counter-force of reed is increased and the relay pressure transient phenomenon that causes, improves shock resistance.
Lamellar body of the present invention is also provided with contact holes, and place, the junction straight line of described bending sheet and lamellar body is through the center of described contact holes.Make the application point of exerting pressure of dynamic spring main leaf on the axis of movable contact, anti-ring spring main leaf torsion is excessive, and causes electrical parameter easily to change.
Lamellar body of the present invention is provided with contact holes, and described contact holes is circular configuration, and described bending groove is semi-circular shape structure, and described contact holes and the concyclic heart of bending groove, the radius of described bending groove is greater than contact holes, and described movable contact is arranged in contact holes.
Angle between bending sheet of the present invention and lamellar body is 90-179 degree.Different angles has different overtravels.Adapt to different customer demands.
Angle between bending sheet of the present invention and lamellar body is 175 degree.There is best effect.Namely there is longer overtravel, be unlikely to again to make bending sheet be folded over multi-angle and make it damage.
Lamellar body of the present invention is also provided with connecting hole.Connect simple, shockproof properties is good.
Lamellar body of the present invention and bending sheet are integral type structure.Structure is simple, low cost of manufacture, long service life.
Contact holes diameter of the present invention is 6.5 millimeters, and the thickness of described lamellar body is 0.2-0.3 millimeter.Optimum size, has best effect.
The part protuberance of the little curved supporting spring of dynamic spring of the present invention and the large curved supporting spring of dynamic spring, described protuberance direction down.Structure is simple, makes magnetic latching relay move spring group and has certain elasticity.
The end bending of the large curved supporting spring of dynamic spring of the present invention downwards.
The present invention compared with prior art, has the following advantages and effect: shock resistance is strong, and overtravel is long, makes movable contact and stationary contact contact greatly, and manufacture simple, cost is low, and structure is simple, easy for installation, safe and reliable.
