Abstract
A kind of thermostat overtemperature protection structure.The utility model comprises the thermostat body and is arranged at the fixed touching plate of thermostat and the thermal cut-off between the binding post, its characteristics are that thermal cut-off comprises the spring leaf of the bearing that is installed on fixed touching plate and is installed on the brace of the bearing of binding post, are provided with between wherein said spring leaf and the brace to be used for tin point that spring leaf and brace are connected.The utility model since adopt by spring leaf and brace and between the thermal cut-off that constitutes of tin point; make the utility model when the thermostat body is malfunctioning; tin point between spring leaf and the brace is under conduction of heat; heat up rapidly and reach fusing point; and under the effect of spring leaf self bounce; cut off electric current rapidly, realize protection electrical equipment, reach the purpose that the accident that averts a calamity takes place.And have that structure is very simple, highly sensitive, action time is shorter, high reliability features.
Description
Technical field
The utility model relates to a kind of thermostat, particularly a kind of overtemperature protection structure that is arranged on the thermostat.
Background technology
At present, the thermostat that has overheat protective function that electric heater is used mainly comprises the thermostat body and is arranged at the fixed touching plate of thermostat and the thermal cut-off between the binding post." a kind of thermostat structure-improved " disclosed as Chinese patent ZL97211114.X, it mainly is by Thermal Cutoffs being nested with in the hole that is curled into by binding post one end on adjustable thermostat, and Thermal Cutoffs one end is crimped on the binding post, the other end then outputs on the electrical equipment.Because the thermal cut-off of this structure is to be nested with in the curling hole that thermostat is provided with by Thermal Cutoffs to constitute, when its thermostat is malfunctioning, be to conduct to curling hole by heat earlier, the hole temperature of curling is raise, realize temperature conduction in the hole of curling then again to Thermal Cutoffs.Therefore, the thermal cut-off that mode constituted of this employing structure exists long action time, poor sensitivity, complex structure and other problems.
Summary of the invention
The purpose of this utility model is to solve above-mentioned existing problems, and what provide that a kind of structure is more simple, highly sensitive, action time is shorter is arranged at overtemperature protection structure on the thermostat.
The technical solution of the utility model is achieved in that
A kind of thermostat overtemperature protection structure; comprise the thermostat body and be arranged at the fixed touching plate of thermostat and the thermal cut-off between the binding post; its characteristics are that thermal cut-off comprises the spring leaf of the bearing that is installed on fixed touching plate and is installed on the brace of the bearing of binding post, are provided with between wherein said spring leaf and the brace to be used for tin point that spring leaf and brace are connected.
In order further to improve the utility model sensitivity, make its action time more short, reliability is higher, above-mentioned spring leaf inboard is provided with and is used to strengthen that it is flexible and slightly be shorter than the shell fragment that helps of spring leaf, this helps shell fragment one end to be fixed on the stiff end place of spring leaf bottom surface, on the fixed leg, the other end is installed on its medial surface along the medial surface bending of spring leaf.
The utility model since adopt by spring leaf and brace and between the thermal cut-off that constitutes of tin point; make the utility model when the thermostat body is malfunctioning; tin point between spring leaf and the brace is under conduction of heat; heat up rapidly and reach fusing point; and under the effect of spring leaf self bounce; cut off electric current rapidly, realize protection electrical equipment, reach the purpose that the accident that averts a calamity takes place.And have that structure is very simple, highly sensitive, action time is shorter, high reliability features.Simultaneously, be provided with the structure that helps shell fragment owing to adopt in the inboard of spring leaf, make spring leaf under the tensioning that helps shell fragment, quicker realization separates with brace, thereby improves the sensitivity and the reliability of the utility model effect further.
Below in conjunction with accompanying drawing the utility model is further described.
