A static contact component and a moving contact component are arranged inside the casing, the adjusting pivot is connected with the diaphragm chamber via a post rod, the diaphragm chamber inner cavity communicates with the capillary tube and the probe via the inner bore of the post rod, the diaphragm chamber, the capillary tube and the probe are filled with temperature sensitive liquid, an upper spring plate and a lower spring plate are positioned on a fulcrum arranged inside the casing, a pressure lever connected with the lower end of the diaphragm chamber is abutted against and pressed on the lower spring plate, the two ends of a tension spring are respectively hung on the upper spring plate and the lower spring plate, and the upper spring plate is connected with the moving contact component. The double-pole switch temperature controller provided in the utility model overcomes the shortcomings of the prior double-pole switch temperature controller including limitation of contact force generated during being switched on/off and narrow application range, and adopts tension spring toggle controlling structure to reliably realize controlling of high-power circuit with over 30A; and has the advantages of simple structure, wide application range, high sensitivity, and high reliability.
Description
Affiliated technical field
The utility model relates to a kind of double-pole switch thermostat.
Background technology
Traditional double-pole switch thermostat all adopts liquid expanding temperature-sensitive, the direct or indirect transmission reed structure of beating, and the motion of its generation is subjected to certain restriction in the contact force that disconnects and produce when closed.At present this kind constructed products can only be controlled the circuit below the 20A, otherwise the too high meeting of electric current makes the contact produce electric arc, spark, carbon deposit etc., thereby causes the contact burn, and is bonding, conducts electricity the decline of potential safety hazard such as bad and serviceability.
Summary of the invention
Be subjected to certain restriction in order to overcome the contact force that common double-pole switch thermostat produces in the prior art when disconnecting with closure, scope of application problem of smaller, the utility model provides a kind of double-pole switch thermostat, simple in structure, applied widely, the good reliability of this double-pole switch thermostat.
The technical scheme that its technical problem that solves the utility model adopts is: comprise housing, binding post, probe, capillary, axle is revolved in bellows and adjusting, be provided with fixed contact and moving contact component in the housing, adjusting is revolved axle and is linked by push rod and bellows, the bellows inner chamber is by the endoporus and the capillary of push rod, probe is communicated with, bellows, fill thermo-responsive liquid in capillary and the probe, location upper spring plate and lower spring plate on the fulcrum in housing, the depression bar roof pressure that the bellows lower end links is on the lower spring plate, the two ends of extension spring are hooked on respectively on upper spring plate and the lower spring plate, and the upper spring plate links to each other with moving contact component.
Moving contact is fixed on the moving contact support plate, and the moving contact support plate links to each other with the upper spring plate.
The utility model is by above-mentioned specific design, adopt extension spring beat type handle structure, when increasing the contact contact force, displacement is amplified, add double-pole switch control, improved the electricity function index of product to a great extent, can reliably realize control, have advantage simple in structure, applied widely, highly sensitive, good reliability the above high-power circuit of 30A.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the partial structurtes schematic diagram of the utility model under dynamic and static contact closure condition.
Embodiment
As shown in the figure, the utility model comprises housing 1, binding post 2, probe 3, capillary 4, axle 6 is revolved in bellows 5 and adjusting, axle 6 and housing 1 threaded engagement are revolved in adjusting, be provided with fixed contact 7 and moving contact component in the housing 1, adjusting is revolved axle 6 and is linked by push rod 9 and bellows 5, bellows 5 inner chambers are by the endoporus 10 and capillary 4 of push rod 9, probe 3 is communicated with, bellows 5, fill thermo-responsive liquid in capillary 4 and the probe 3, location upper spring plate 11 and lower spring plate 12 on the fulcrum in housing 1, depression bar 15 roof pressures that bellows 5 lower ends link are on lower spring plate 12, the two ends of extension spring 13 are hooked on respectively on upper spring plate 11 and the lower spring plate 12, and upper spring plate 11 links to each other with moving contact component.Moving contact 8 is fixed on the moving contact support plate 14, and moving contact support plate 14 links to each other with upper spring plate 11.Under user mode, revolving axle 6 rotation promotion push rods 9 by adjusting makes bellows 5 set temperature required controlling value, after probe 3 is experienced heat energy from thermal source, intracavity liquid expands, conduct to bellows 5 by capillary 4, make bellows 5 produce an edge adjusting and revolve the downward monodisplacement in axle 6 centers, the depression bar 15 that bellows 5 lower ends link conducts to lower spring plate 12 with the power that displacement movement produces, lower spring plate 12 is done to stick up transhipment down along the fulcrum shaft alignment and is moved, driving upper spring plate 11 by extension spring 13 simultaneously moves downward, along with the increase of displacement, two latch plates are tending towards level gradually, when extension spring 13 be subjected to the force direction level time, reach the critical point of beating, break through critical point, extension spring 13 is changed by force direction thereupon, makes upper spring plate 11 produce downward kick under the effect of extension spring power.Moving contact support plate 14 that links to each other with upper spring plate 11 and moving contact 8 move thereupon, and moving contact 8 separates with fixed contact 7, thereby produce switch motion.When the heated body temperature descends, liquid contraction in the probe 3, the reverse displacement of bellows 5 reset generation, under the active force of extension spring 13, lower spring plate 12 moves upward, when breaking through critical point, direction of pull changes, make upper spring plate 11 produce kick upwards, moving contact 8 and fixed contact 7 closures are connected the circuit connection and are reworked.
