Description

A kind of adjustable overcurrent non-electricity protector
Technical field
The utility model relates to a kind of non-electricity protector, particularly relates to a kind of when the electric equipment such as motor, compressor is at overcurrent overheat, energy automatic cut-off power, the overcurrent non-electricity protector preventing it from burning.
Background technology
Existing overcurrent non-electricity protector, comprise the metal shell of bottom opening, close the metal base plate of described outer casing bottom opening, be provided with moving contact and overturn when reaching design temperature, lower than the temperature-sensitive plate resetted during design temperature, the fixed contact arranged corresponding to described moving contact, and heating plate and two binding posts; The lower end of described two binding posts is each passed through described base plate and stretches in the confined space that shell and base plate form, the shaft of described two binding posts is connected with described base plate insulated enclosure respectively, described fixed contact is fixedly mounted on the lower end of one of them binding post, one end of described heating plate is weldingly fixed on the lower end of another binding post, the other end and the described base plate of heating plate are welded and fixed, in described confined space, be packaged with mist.
There are following two defects in actual use in above-mentioned existing non-electricity protector:
(1) for different use occasions; protector confined space domestic demand however with heat in other words temperature to mate corresponding overload current; thus make the upset power-off when reaching setting overcurrent value of temperature-sensitive plate; the method that technical staff adopts usually changes the heating plate with different resistance values be made up of unlike material, in other words by adopting the heating plate of unlike material to realize protecting the coupling of plurality of target overload current value.The weak point of the method is: owing to can meet the heating plate limited material of batch production requirements, usually stainless steel is only had, corronil or copper three kinds of materials are applicable to using, again because the resistance value span between different materials is larger, span often has tens of, even hundreds of ohm, thus it is consequently accidents caused to cause protector temperature-sensitive plate when reaching setting overcurrent value not overturn power-off, or temperature-sensitive plate early overturns power-off so that affects electrical equipment and normally works when not reaching setting overcurrent value, therefore, said method directly causes the protection precision of protector lower, greatly reduce promptness and the reliability of protector,
(2) after heating plate and binding post and base plate are welded and fixed, protector can only carry out coupling protection for a kind of overload current value, therefore greatly reduces the scope of application and the use occasion of protector.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of heating plate do not needed by adopting unlike material; just can realize protecting the coupling of plurality of target overload current value; and protection precision is high; protection more in time with reliable, and can expand the scope of application of protector and the adjustable overcurrent non-electricity protector of occasion.
For solving the problems of the technologies described above, the utility model adopts so a kind of adjustable overcurrent non-electricity protector, for by compressor or the motor failure of current when overcurrent overheat operating mode, it comprises the metal shell of bottom opening, close the metal base plate of described outer casing bottom opening, be provided with moving contact and the upset when reaching setting overcurrent value, lower than the temperature-sensitive plate that resets during setting overcurrent value, the fixed contact arranged corresponding to described moving contact, and heating plate and two binding posts, the lower end of described two binding posts is each passed through described base plate and stretches in the confined space that shell and base plate form, the shaft of described two binding posts is connected with described base plate insulated enclosure respectively, described fixed contact is fixedly mounted on the lower end of one of them binding post, one end of described heating plate is fixedly mounted on the lower end of another binding post, the other end of heating plate is fixedly connected with described base plate, mist is packaged with in described confined space, gusset between described heating plate two ends is provided with one and is used for temperature in fine adjustment confined space, make the rectangular recess run through that described temperature-sensitive plate overturns immediately when reaching setting overcurrent value.
In the utility model, the length of described rectangular recess is preferably 2.5 ~ 3.5mm, and width is preferably 0.1 ~ 0.8 mm.
In the utility model, described heating plate thickness is preferably 0.1 ~ 0.6mm.
As a kind of preferred implementation of the present utility model, described rectangular recess is arranged on one end place that on gusset, contiguous heating plate is fixedly connected with base plate.
After adopting such structure, the utility model has following beneficial effect:
Due to the gusset of the utility model between heating plate two ends arranging a rectangular recess; the large I of this rectangular recess for different use occasions, protector confined space domestic demand however with temperature and adjust; like this by changing the length of rectangular recess, width and the caloric value of fine adjustment heating plate in confined space; thus the temperature in fine adjustment confined space; make temperature-sensitive plate when reaching setting overcurrent value; temperature in confined space also just in time reached thermal critical point; impel temperature-sensitive plate to overturn power-off immediately, stop the generation of burnout failure.
Because the utility model only need get final product the caloric value of fine adjustment heating plate in confined space by the length of adjustment rectangular recess, width; therefore in different use occasions; do not need the heating plate changing unlike material, just can realize carrying out coupling protection to plurality of target overload current value.
Because the length of the utility model rectangular recess, width can accurately control, thus accurately control the temperature in the caloric value of heating plate and confined space, therefore substantially increase the protection precision of protector, make it protect more timely, security performance is more reliable.
The utility model heating plate, when identical material, can realize protecting the coupling of plurality of target overload current value.
Even if the utility model is after heating plate is fixedly connected with binding post and base plate; also expand rectangular recess by cutting implement or reduce rectangular recess by soldering appliance; thus change the caloric value of heating plate in confined space; therefore make same protector can carry out coupling protection for multiple overload current value, greatly expand the scope of application and the use occasion of protector.
