Background technology
Thermal protector is that a kind of bimetal leaf that utilizes can to reverse rapidly the Protector for electric appliances disconnected exceeding in protection temperature range.At present, bimetal leaf on existing thermostat is generally arranged on the end face of movable contact spring, its mounting means generally has three kinds: Yi Zhongshi, the end face of movable contact spring has been made two hooks, the two ends of described bimetal leaf are fastened in two hooks of movable contact spring end face respectively, such mounting means no-trump bimetal leaf are fixed, and cause bimetal leaf be easy to displacement or lose, make it exist and install unstable shortcoming; Two kinds are, the end face of movable contact spring is made two hooks in left and right and has bent positions at upper and lower two, first the two ends of bimetal leaf are fastened on respectively in two hooks of movable contact spring end face during installation, with pliers, two twisting bending positions upwards will be bent again, bimetal leaf is spacing, and such mounting means makes it upwards bend process to rupture, make its defective products rate high in twisting bending position, bending position is generally smaller, causes it to also have and installs inconvenient shortcoming; Three kinds are, movable contact spring end face has been made two hooks, two bayonet sockets are respectively equipped with at the two ends of bimetal leaf, on bimetal leaf two bayonet socket is coordinated with the hook on movable contact spring respectively and is connected together, such assembling mode needs bayonet socket and hook to carry out contraposition when assembling, because the area of bayonet socket and hook is all smaller, causes it to bit comparison difficulty, make it exist and inconvenient shortcoming is installed; Above three kinds of mounting meanss are all need manually to assemble, and make that its production efficiency is low, production cost is high and be not suitable with the shortcoming of production line balance.
Utility model content
The purpose of this utility model is to provide a kind of thermal protector, and this thermal protector has that temperature control is accurate, easy for installation, firm, production efficiency is high and be used in the advantages such as production line balance.
The technical solution of the utility model is achieved in that
A kind of thermal protector, comprise insulating base, metal fixing, moving contact, movable contact spring, fixed contact, bimetal leaf, the first terminals, the second terminals, its feature is end face one end being fixedly mounted on insulating base of described metal fixing; Described bimetal leaf is stacked on the end face of movable contact spring, and one end of this bimetal leaf and one end of movable contact spring are together fixed on metal fixing by rivet, and the end face of described movable contact spring is provided with hook; The described bimetal leaf other end is fastened in hook; Also boss is provided with in the middle part of the end face of described insulating base; Described movable contact spring is provided with the through hole passed for boss top; Described first terminals, the second terminals are arranged on the two ends, bottom surface of insulating base respectively; Described second link is connected with metal fixing; Described fixed contact is arranged on the top of the first terminals, and this fixed contact is connected with the first terminals; Described moving contact is arranged on movable contact spring other end bottom surface, and this moving contact and static contact touch formula mounting structure mutually.
Upspring more rapidly to make bimetal leaf of the present utility model and dynamics stronger, the both sides of described movable contact spring, bimetal leaf have also made two grooves respectively, and described each groove is positioned at the front of metal fixing 2.
In order to make the utility model structure more reasonable, described first terminals have also made installation portion 71, and described fixed contact is arranged on the end face of installation portion.
The utility model, owing to have employed technical scheme noted earlier, can obtain following technique effect:
(1) bimetal leaf is first stacked in the end face of movable contact spring by the utility model, again one end of its one end and movable contact spring is together fixed on metal fixing by rivet, be formed with hook from movable contact spring end face again the other end of bimetal leaf is locked, with the hook on rivet and movable contact spring, bimetal leaf is fixed, make it displacement can not occur and lose, do not need to twist bending position to carry out spacing and to there is not the problem of contraposition difficulty, make it have easy for installation, firmly, the advantage that production efficiency is high, and riveter nail and by fairly simple for operation molded for hook, can complete on streamline.
(2) one end of the utility model bimetal leaf and one end of movable contact spring are fixed on metal fixing by rivet, rivet presses down past for movable contact spring, so that the moving contact on movable contact spring can be close to the fixed contact being arranged on the first link, increase the area of bimetal leaf, make the utility model have temperature control advantage accurately.
