Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, below further describe with reference to the accompanying drawing the utility model of embodiment that develops simultaneously.
As shown in Figure 1, be the structural representation of miniature temperature sensitive magnetic switch in the utility model.This miniature temperature sensitive magnetic switch comprises end cap 100, shell 200 and soft magnetism 300, and shell 200 is arranged to the tubbiness of single-ended sealing, is provided with concave station in the open end of shell 200; Soft magnetism 300 is stuck on the concave station, and end cap 100 is enclosed within the open end of shell 200, and is fixing soft magnetism 300 by concave station and end cap 100; End cap 100 is provided with thermal hole, and soft magnetism 300 directly contacts with heating container or other thermals source by thermal hole.
As depicted in figs. 1 and 2, this miniature temperature sensitive magnetic switch also comprises Hard Magnetic 400, spring 500, actuating strut 610, movable switch 700: described Hard Magnetic 400 is arranged in the shell 200, place soft magnetism 300 below; Spring 500 is arranged between described soft magnetism 300 and the Hard Magnetic 400, and an end of described spring 500 connects soft magnetism 300, and the other end connects Hard Magnetic 400; Blind end and movable switch 700 that actuating strut 610 1 ends pass shell 200 touch, actuating strut 610 and movable switch 700 interoperations, and the other end is fixedlyed connected with Hard Magnetic 400.Concrete, described Hard Magnetic 400 centers arrange via, described via is made up of the concentric column through hole of two connections of upper and lower settings, top cylindrical hole radius is greater than following cylindrical hole radius, junction at two cylindrical holes forms groove, and described actuating strut 610 tops protrusion, and actuating strut 610 passes the via of Hard Magnetic 400, the groove in Hard Magnetic 400 vias is blocked at the top of actuating strut 610, realizes actuating strut 610 and Hard Magnetic 400 relative fixed.
In order further to increase the stability of actuating strut 610 and Hard Magnetic 400, in the bottom surface of Hard Magnetic 400 Hard Magnetic pallet 620 is set, as shown in Figure 4, Hard Magnetic pallet 620 toroidals in the present embodiment, Hard Magnetic pallet 620 circle centre positions have through hole, actuating strut 610 passes the through hole of the circle centre position of Hard Magnetic pallet 620, and Hard Magnetic pallet 620 places Hard Magnetic 400 bottom surfaces.Because Hard Magnetic 400 and soft magnetism 300 can produce some magnetics when miniature temperature sensitive magnetic switch used for a long time, in the present embodiment, influence the operate as normal of miniature temperature sensitive magnetic switch in order to prevent that magnetic from dropping, described Hard Magnetic pallet 620 areas are more bigger than Hard Magnetic 400, when the magnetic of Hard Magnetic 400 or soft magnetism 300 generations drops, fall on the Hard Magnetic pallet 620, can not influence the operate as normal of miniature temperature sensitive magnetic switch.
In order to prevent that Hard Magnetic pallet 620 from sliding at actuating strut 610, in Hard Magnetic pallet 620 bottoms snap ring 630 is set and fixes Hard Magnetic pallet 620, simultaneously the top bump place of snap ring 630 and actuating strut 610 fixedly Hard Magnetic 400 and Hard Magnetic pallet 620 jointly makes Hard Magnetic 400, actuating strut 610, Hard Magnetic pallet 620 and snap ring 630 motions in aggregates.Concrete, as shown in Figure 3, at the body of rod of actuating strut 610 groove is set, as shown in Figure 5, the shape of snap ring 630 be arranged to actuating strut 610 bodies of rod on the groove coupling, snap ring 630 is stuck on the groove fixing.
Described movable switch 700 comprises electroconductive elastic sheet 710 and quiet conducting strip 720: blind end and electroconductive elastic sheet 710 that described actuating strut 610 passes shell 200 touch, described quiet conducting strip 720 is arranged on the outer surface of shell 200 blind ends, quiet conducting strip 720 is provided with fixed contact, the stiff end of electroconductive elastic sheet 710 is arranged on the outer surface of shell 200 blind ends, the movable end of electroconductive elastic sheet 710 is provided with moving contact, and described fixed contact contacts with the moving contact cooperation; Described quiet conducting strip 720 is connected with a splicing ear 120 respectively with electroconductive elastic sheet 710, described splicing ear 120 circumscripted power lines.
The inner surface of the blind end of described shell 200 is provided with the groove with snap ring 630 form fit.
In actual the use, described actuating strut 610 is the heat-resisting actuating strut 610 of insulation, described Hard Magnetic pallet 620 is the heat-resisting Hard Magnetic pallet 620 of insulation, insulate the fusing point of heat-resisting actuating strut 610 and the heat-resisting Hard Magnetic pallet 620 of insulation greater than the Curie temperature of soft magnetism 300, can avoid when the temperature sensitive magnetic switch conducting by this setup, actuating strut 610 and the Hard Magnetic pallet 620 charged magnetic that influence Hard Magnetic influence the result of use of product; When adopting the heat-resisting actuating strut 610 of insulation and the heat-resisting Hard Magnetic pallet 620 of insulation can prevent the soft magnetism heat temperature raising on the other hand, actuating strut 610 and Hard Magnetic pallet 620 melt, and are conducive to prolong the useful life of product.
Further, in order better to realize the insulation effect of Hard Magnetic pallet 620, increase security of products, the thickness of described Hard Magnetic pallet 620 is greater than 0.5mm.In the practical application, the Hard Magnetic pallet can be arranged to circle, ellipse or square.
For the internal structure that prevents miniature temperature sensitive magnetic switch is not subjected to external interference, the blind end of described shell 200 is with rotation sliding sleeve 800.
Under the initial condition, the magnetic force that produces between soft magnetism 300 and the Hard Magnetic 400 overcomes the elastic force of spring 500, soft magnetism 300 and Hard Magnetic 400 contact with each other, spring is compressed, actuating strut 610 leaves electroconductive elastic sheet 710, the fixed contact of quiet conducting strip 720 contacts with the moving contact of electroconductive elastic sheet 710 and entire circuit is connected, and soft magnetism 300 is directly heated by the heating container; When soft magnetism 300 is heated to the operating point temperature, soft magnetism 300 loses magnetism, magnetic force between soft magnetism 300 and the Hard Magnetic 400 disappears, Hard Magnetic 400 moves downward under the drive of spring 500, actuating strut 610 moves downward thereupon, promote electroconductive elastic sheet 710 and move downward thereupon, the fixed contact of quiet conducting strip 720 separates with the moving contact of electroconductive elastic sheet 710 and entire circuit is disconnected, and soft magnetism 300 is stopped heating; When the temperature of soft magnetism 300 drops to when being lower than the operating point temperature, soft magnetism 300 and Hard Magnetic 400 be adhesive mutually again, and entire circuit is conducting thereupon, so repeats above-mentioned action.
Because Hard Magnetic 400, actuating strut 610, Hard Magnetic pallet 620 and snap ring 630 are in aggregates, in actuating strut 610 motion processes, actuating strut 610 and Hard Magnetic 400 can not be offset, and guarantee fail safe of the present utility model and stability.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or conversion, all these improvement and conversion all should belong to the protection range of the utility model claims.
