Description
Technical field
The utility model relates to a kind of protector, particularly a kind of external structure of current over-load protector.
Background technology
Most protector is applied on the electric tool such as motor, ballast; day by day accurate small and exquisite along with these tool designs; it is more and more less that the structure of protector also designs; Mini-sized protector is little due to volume, is not only conveniently installed to narrow and small position and also can be installed on required product by mosaic mode.The key structure of protector is the installation of temperature-sensing element; it installs quality and configuration design is related to protector disconnection precision and life-span; be exactly the temperature-sensitive problem of protector in addition; protector now all adopts shell to encapsulate in order to security seal; but the effect of temperature-sensing element is affected, thus the operating accuracy affecting protector can be affected.
Utility model content
The purpose of this utility model is to provide a kind of open type thermostat being beneficial to temperature-sensitive.
The technical scheme realizing the utility model object is:
A kind of open type thermostat, there is insulating base, first and second brace, movable contact spring, sensing element, first and second conducting strip, heater element, above-mentioned first brace is provided with fixed contact, movable contact spring is provided with corresponding moving contact, above-mentioned insulating base upper surface is provided with bar-shaped trough, and above-mentioned sensing element, movable contact spring and the second brace are fixed in above-mentioned bar-shaped trough successively.
Above-mentioned insulating base lower surface is provided with square groove, and above-mentioned first conducting strip, heater element and the second conducting strip are fixed in above-mentioned square groove successively; Above-mentioned first conducting strip is electrically connected with the second brace, and the second conducting strip is electrically connected with the first brace.
Above-mentioned sensing element, movable contact spring, the second brace and the first conducting strip are separately fixed at insulating base upper and lower surface by the first rivet; Above-mentioned first brace and the second conducting strip are separately fixed at insulating base upper and lower surface by the second rivet.
What benefit of the present utility model was that this novel temperature-sensing element is freely arranged on insulating base shows in mounting groove up and down, and does not add closure, is conducive to dispelling the heat; Utilize rivet to be fixedly connected with reliability high, also improve the electric conductivity between element.
Accompanying drawing explanation
Fig. 1 is generalized section of the present utility model.
Fig. 2 is detonation configuration schematic diagram.
Embodiment
See Fig. 1 and Fig. 2, this novel open type thermostat is made up of the first brace 1, the fixed contact 2 be located on the first brace, movable contact spring 4, the moving contact 3 being located at movable contact spring one end, sensing element 5, second brace 6, first and second rivet 7,9 and insulating base 12.Fixed contact 2 is arranged on the first brace 1 middle bench, one end of first brace 1 and insulating base 12 one end are fixed by the second rivet 9, moving contact 3 is arranged at one end of movable contact spring 4, sensing element 5, movable contact spring 4, second brace 6 are fixed in the bar-shaped trough 121 of insulating base 12 upper surface successively, and fixed by the first rivet 7, form path when dynamic and static contact is touched.The sensing element 5 of above thermostat is under thermal effect effect, and sudden change upset directly promotes movable contact spring 4 and produces displacement, and moving contact 3 is separated with fixed contact 2, thus cuts off circuit loop; After on sensing element, heat leaves, sensing element 5 can automatically reset recovery, and movable contact spring resets under elasticity operation, and moving contact and fixed contact touch again, turning circuit.
Above-mentioned insulating base 12 lower surface is provided with square notch, is used for putting into the first conducting strip 8 and heater element 11.First conducting strip 8 is connected with the second brace 6 by rivet 7, heater element 11 is provided with the second conducting strip 10, be connected with the first brace 1 by the second rivet 9 for fixing heater element 11, second conducting strip 10, be more than connected to form the parallel circuits between heater element 11 and dynamic and static contact.When dynamic and static contact is in conducting state, heater element 11 is shorted absence of voltage, does not generate heat; After dynamic and static contact disconnects, there is voltage difference at heater element 11 two ends starts heating, and heat passes to sensing element, makes sensing element remain on rotary movement state, continue to disconnect dynamic and static contact path.After cutting off the electricity supply by hand, heater element 11 no longer generates heat, and automatically resets along with heat eliminates sensing element again, dynamic and static contact path recovery on-state.
This Noval temp .-control does not arrange shell, be beneficial to temperature-sensing element temperature-sensitive, improve temperature control accuracy and reaction efficiency, heater element 11 be arranged in parallel the fail safe that improve whole circuit, namely, only under artificial power-off is intervened, dynamic and static contact path could conducting again.
Obviously, above-mentioned embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to the utility model execution mode.For those of ordinary skill in the field, can also be easy to make other pro forma change on the basis of the above description or substitute, and these change or substitute and also will be included within protection range that the utility model determines.
