Description
[technical field]
The utility model relates to a kind of open type temperature protector.
[background technology]
The bimetal leaf temperature switch of using at present mainly comprises base, silver strip assembly, bimetal leaf, movable contact spring, moving contact, shell etc.Adopt solder technology, said modules is welded into as a whole, temperature protector is an enclosed construction, and bimetal leaf dares to ask that part is in free state during work, moving contact and silver strip assembly closure, circuit turn-on.When electrical equipment makes temperature rise to the operating temperature of temperature protector because of heating; Shell is heated and conducts to bimetal leaf; Bimetal leaf is heated and produces internal stress and action rapidly, pushes moving contact open and leaves the silver strip assembly and open circuit, plays a protective role thereby cut off appliances power source.When being dropped to the specified reset temperature value of temperature protector by protection electrical equipment temperature, bimetallic element returns to the initial condition closing of contact, and electrical equipment recovers operate as normal.But mainly there is following shortcoming in existing bimetal leaf temperature protector: bimetal leaf directly is not heated in the existing structure, and the medium conduction causes the suffered thermal loss of bimetal leaf when being heated; There is not memory function.
[summary of the invention]
For solving the problems of the technologies described above, the utility model provides a kind of open type temperature protector simple in structure, easy to use, and response is rapid, and the current lead-through performance is good, and is high to the protection coefficient of safety of electrical equipment.
The open type temperature protector of the utility model; Comprise pedestal, the left side of said pedestal is provided with first lug plate, and the right-hand member overlap joint of first lug plate is fixed on pedestal and through rivet A; The top of first lug plate is provided with the static contact spring piece that extends to the left, and the top of static contact spring piece is provided with fixed contact; The right side of said pedestal is provided with second lug plate; The left end overlap joint of second lug plate is fixed on pedestal and through rivet B; Connecting circuit fault memory storage between the bottom of the bottom of rivet B and rivet A; Be provided with movable contact spring between the left end portion of second lug plate and the pedestal, the left end bottom of movable contact spring is provided with the moving contact that is resisted against on the fixed contact, is provided with bimetal leaf in the cavity that movable contact spring and static contact spring piece and pedestal form.
The open type temperature protector of the utility model, said fault memory storage comprise compressing tablet that is arranged on rivet A bottom and the conducting strip that is arranged at rivet B bottom, and the PTC heater is set between conducting strip and the compressing tablet.
The open type temperature protector of the utility model, the said movable contact spring corresponding with the bimetal leaf end positions are provided with to the recessed arcuation in movable contact spring below protruding.
The open type temperature protector of the utility model, the middle part of said bimetal leaf is arranged on the pedestal, and the two ends of bimetal leaf extend to arc structure downwards.
Compared with prior art the beneficial effect of the utility model is: the pedestal of the open type temperature protector of the utility model, movable contact spring, moving contact adopt riveted structure; Increased the current lead-through performance of temperature protector, effectively reduced internal resistance, unenclosed construction directly is heated by bimetal leaf; Reduced the response time of temperature protector; PTC heater pseudomemory temperature, electrical equipment is the holding circuit off-state before fixing a breakdown, and has greatly improved coefficient of safety.

[embodiment]
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Shown in Fig. 1-2; A kind of open type temperature protector; Comprise pedestal 1, the left side of said pedestal 1 is provided with the right-hand member overlap joint of first lug plate, 2, the first lug plates 2 and on pedestal 1 and through rivet A3, fixes; The top of first lug plate 2 is provided with the static contact spring piece 4 that extends to the left, and the top of static contact spring piece 4 is provided with fixed contact 5; The right side of said pedestal 1 is provided with second lug plate 6; The left end overlap joint of second lug plate 6 is fixed on pedestal 1 and through rivet B7; Connecting circuit fault memory storage between the bottom of the bottom of rivet B7 and rivet A3; Be provided with movable contact spring 8 between the left end portion of second lug plate 6 and the pedestal 1, the left end bottom of movable contact spring 8 is provided with the moving contact 9 that is resisted against on the fixed contact 5, is provided with bimetal leaf 10 in the cavity of movable contact spring 8 and static contact spring piece 4 and pedestal 1 formation.
The open type temperature protector of the utility model, said fault memory storage comprise compressing tablet 11 that is arranged on rivet A3 bottom and the conducting strip 12 that is arranged at rivet B7 bottom, between conducting strip 12 and the compressing tablet 11 PTC heater 13 are set.
The open type temperature protector of the utility model, the said movable contact spring 8 corresponding with bimetal leaf 10 end positions are provided with to the recessed arcuation protruding 14 in movable contact spring 8 belows.
The open type temperature protector of the utility model, the middle part of said bimetal leaf 10 are arranged on the pedestal 1, and the two ends of bimetal leaf 10 extend to arc structure downwards.
When the open type temperature protection implement body of the utility model was worked, said bimetal leaf 10 was in free state, moving contact 9 and fixed contact 5 closures, circuit turn-on.When electrical equipment made temperature rise to the operating temperature of temperature protector because of heating, said bimetal leaf 10 was heated and produces internal stress and action rapidly, pushes moving contact 9 open and leaves fixed contact 5 and open circuit; Thereby cutting off appliances power source plays a protective role; But apparatus failure is not got rid of, and circuital current is excessive, and big electric current is through PTC heater 13; Make PTC heater 13 persistent fevers, let bimetal leaf 10 continue to be heated and can not reset closure.When apparatus failure is got rid of; Recover normal current in the circuit, PTC heater 13 can not generate heat, when being dropped to the specified reset temperature value of said temperature protector by protection electrical equipment temperature; 10 in bimetallic unit returns to the initial condition closing of contact, and electrical equipment recovers operate as normal.PTC heater 13 memory functions are good, improved by protection safety of products coefficient, and unenclosed construction has promoted the response speed of temperature protector.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection range of the utility model.
