Abstract
The utility model relates to a safety protector for electric appliances for protecting the overload, over-current and over-heat of industry power equipment or domestic appliances, which mainly comprises a top cover, a bottom cover, a guide bolt hole, an angle square depressed button, a fixed contact connecting block, a movable contact connecting block and a bimetallic strip, wherein the outer surface of the top cover is provided with a sensing window on which a sensing board is arranged. Whether the hand reset or the automatic reset is adopted, the utility model has the functions of protecting the overload, over-current and the temperature over-heat, and the function of duplicate protection to the electric appliances is obtained. The power utilization of the electric appliances is safe, and the function is perfect. The utility model has easy use, and the matched cost of users is decreased.
Description
The utility model relates to a kind of comprehensive safety utilization of electric power protective device, especially relates to a kind of security appliance protector that is used for industrial power-equipment, the overtemperature protection of household electrical appliance overload flow.
At present; the quiet terminal block of traditional power consumption equipment protector connects moving terminal block through bimetal leaf and is serially connected in the load; when load is broken down when causing overload flow; make bimetal leaf that the antiarch deformation that fixed contact, moving contact are separated take place; angle square position on the angle square button is embedded between fixed contact, the moving contact, make fixed contact, moving contact be in off state.Restore to the original state after fault is got rid of the bimetal leaf cooling, fixed contact and moving contact can't conductings.As desire to make load to work on, then must press the angle square button by manual reset.Above-mentioned protector can not automatically reset, and also is only limited to the overload flow protection on function, and does not have the temperature overheating protection.
The purpose of this utility model provide a kind of improved, automatically reset and a kind of comprehensive security appliance protector of temperature overheating defencive function keeping to have increased on the basis of prior art.
The purpose of this utility model is achieved in that a kind of comprehensive security appliance protector; it mainly comprises loam cake, bottom, guiding screw, angle square button, fixed contact terminal block, moving contact terminal block, bimetal leaf, and the outer surface of loam cake has on induction window, the induction window and is equipped with tablet.Tablet adopts the big metal material of conductive coefficient.
The task that the utility model proposed also can further be realized by following technical solution: the top of angle square button is equipped with latch-up structure; This latch-up structure is a cap nut; This latch-up structure is for having the pin that passes through the angle square button on the guiding screw.
The utility model is owing to adopt technique scheme; no matter the security appliance protector is the employing hand-reset or automatically resets; all have overload flow protection and temperature overheating defencive function; reached double protection to electric equipment; make more become safety, function of electric equipment electricity consumption more become perfect, and supporting cost easy to use, that reduced the user.
Below in conjunction with accompanying drawing and specific embodiment of the utility model the utility model is described in further detail:
Fig. 1, Fig. 2, Fig. 3 are the utility model structural representation.
With reference to Fig. 1, Fig. 2, Fig. 3.The utility model mainly comprises loam cake 1, bottom 2, guiding screw 3, angle square button 4, fixed contact terminal block 5, moving contact terminal block 6, bimetal leaf 7, the outer surface of loam cake 1 has on induction window 8, the induction window 8 and is equipped with tablet 9, the top of angle square button 4 is equipped with cap nut 10, on the guiding screw 3 pin 11 that passes through angle square button 4 is arranged.
Embodiment 1: with reference to Fig. 1.Quiet terminal block of the present utility model, moving terminal block are serially connected in the load, simultaneously tablet are pasted at the end face of load or place easy heating place.When load is in abnormal operating state (overload flow, overheated); as when the overload flow defencive function that relies on prior art is not had an effect; also can rely on bimetal leaf to induce in addition and paste the heat energy that tablet gives off in load; make the deformation of bimetal leaf generation antiarch; under the angle square button effect of spring (not providing in the accompanying drawing) within it simultaneously the angle square position is embedded between fixed contact, the moving contact (not providing in the accompanying drawing); make fixed contact, moving contact be in off state, thereby reach safeguard protection load.After load faulty was got rid of, manual reset was pressed the angle square button, makes fixed contact, moving contact conducting, and load can recover normal operating conditions.
Embodiment 2: with reference to Fig. 2, Fig. 3.The utility model is provided with a latch-up structure on the angle square button, this latch-up structure is cap nut and pin.Its objective is when bimetal leaf overload flow, overheated generation antiarch deformation, spring in the angle square button is not had an effect, thereby make the angle square position can not embed between fixed contact, the moving contact all the time, like this after the overload flow in the load, superheat state are eliminated, when bimetal leaf is restored to the original state by antiarch deformation, the conducting that automatically resets between fixed contact, the moving contact must be pressed the manual reset mode that the angle square button just can make conducting between fixed contact, the moving contact thereby remove from.
