Abstract
A square inner-chamber temperature controller comprises a housing, a bimetallic strip, a contact pair and an actuator, and is characterized in that the contact pair comprises a fixed contact and a moving contact; a first connection terminal is fixed on the housing through a first rivet; a second connection terminal is fixed on the housing through a second rivet; the fixed contact is connected to the first rivet through a pressure plate; and the moving contact is connected to the second rivet through a reed. In comparison with the prior art, the utility model has advantages as follows: the contact pair is respectively electrically connected with the connection terminals through the rivets, safe creepage distance between the contacts and the terminals can be increased effectively so as to raise use security and reliability, and whole performance of the temperature controller is raised.
Description
Technical field
The utility model relates to a kind of thermostat, particularly a kind of square cavities thermostat.
Background technology
In prior art; it is a kind ofly for industry, household appliance, to make temperature control or make the thermostat of overtemperature prote that the Chinese utility model < < that is ZL97245930.8 if any patent No. Noval temp .-control > > discloses, and this thermostat includes base, housing, lid, bimetal disk, actuating strut, moving contact component and determines contact assembly.Moving contact component in this patent and determine contact assembly owing to adopting the version of directly riveting, fluffs therefore can avoid riveting position, thereby can guarantee that its electric conductivity is good.
But binding post and contact in above-mentioned are direct electrical connections, distance is between the two less, although enough meet the requirement of minimum creep distance, in long-time use or the larger situation of operating voltage, cannot guarantee the fail safe used to need to make further improvement.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned prior art present situation, to provide a kind of simple in structure and use safer square cavities thermostat.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of square cavities thermostat, includes
Housing, is externally connected to the first binding post and the second binding post;
Bimetal leaf, is arranged in described housing;
Contact pair, is electrically connected to the binding post of described outside respectively; And
Actuator, under the effect of described bimetal leaf, makes described contact to closed or disconnection;
It is characterized in that: described contact is to including fixed contact and moving contact, described the first binding post is fixed on described housing by the first rivet, described the second binding post is fixed on described housing by the second rivet, described fixed contact is connected with described the first rivet by pressing plate, and described moving contact is connected with described the second rivet by reed.
As preferably, described actuator is the push rod that the center curvature face inside of one end and described bimetal leaf offsets; Described bimetal leaf is under initial reset state, and described moving contact contacts and makes circuit turn-on with fixed contact; Described bimetal leaf is under reverse kick state, and the other end of described push rod upwards backs down described moving contact, and described moving contact make circuit separated with fixed contact disconnects.
As preferably, the openend of described housing is provided with platen, offers the axis hole vertically arranging on this platen, and described push rod is arranged in described axis hole movably.
As further preferred, the outer end of described platen is also provided with end cap, and described bimetal leaf is arranged in the cavity of described platen and end cap formation.
Compared with prior art, the utility model has the advantage of: contact is to realizing and the electrical connection of binding post by rivet respectively, can effectively increase the safety creepage distance between contact and terminal, thereby improve safety in utilization and reliability, improve the overall performance of thermostat.

Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, Figure 2 and Figure 3, the present embodiment is a kind of square cavities thermostat, this thermostat includes housing 1, bimetal leaf 2, contact to, actuator, platen 3 and end cap 4, and wherein, housing 1 is externally connected to the first binding post 51 and the second binding post 52; Bimetal leaf 2 is arranged in housing 1; The openend of housing 1 is provided with platen 3, offers the axis hole 31 vertically arranging on this platen 3, and the outer end of platen 3 is also provided with stainless steel end cap 4, and bimetal leaf 2 is arranged in the cavity of platen 3 and end cap 4 formation.
Contact is to including fixed contact 61 and moving contact 62, in housing 1, be also provided with the first rivet 71 and the second rivet 72, one end of the first binding post 51 is connected with the bottom of the first rivet 71, one end of the second binding post 52 is connected with the bottom of the second rivet 72, fixed contact 61 is connected with the top of the first rivet 71 by pressing plate 91, and moving contact 62 is connected with the top of the second rivet 72 by flexible reed 92.
Actuator is the push rod 8 that the center curvature face inside of one end and bimetal leaf 2 offsets, and push rod 8 is arranged in the axis hole 31 of platen 3 movably; When bimetal leaf 2 is under initial reset state, moving contact 62 contacts and makes circuit turn-on with fixed contact; When bimetal leaf 2 is under reverse kick state, the other end of push rod 8 upwards backs down moving contact 62, and moving contact 62 make circuit separated with fixed contact disconnects.
Under normal temperature state, bimetal leaf 2 is in initial reset state, and moving contact 62 contacts and makes circuit turn-on with fixed contact 61; When stainless steel end cap 4 senses that ambient temperature is elevated to the preset temperature of thermostat, there is reverse kick in bimetal leaf 2, and promote push rod 8 and move upward, and push rod 8 backs down reed 92, thereby moving contact 62 is separated with fixed contact 61, and circuit disconnects; When temperature reduces, bimetal leaf 2 is returned to initial condition, and push rod 8 is pressed downward under the elastic-restoring force effect of reed 92, makes moving contact 62 and fixed contact closed connection again.
