Abstract
The utility model relates to a current-type temperature protector, which comprises a shell, wherein a stainless iron base is arranged on the inner bottom of the shell, the right end of the stainless iron base is bent upwards to form an accordion structure with the cross section of an L shape, a silver sheet assembly is arranged on the stainless iron base to be close to the left end, two metal sheets are arranged above the right side of the silver sheet assembly, the right side parts of the two metal sheets are welded on the left side bottom of the accordion structure, the left end bottoms of the two metal sheets are respectively provided with a movable contact, the movable contacts prop against the silver sheet assembly, the left side shell of the silver sheet assembly is sealed by a sealing device, and the left side of the sealing device is provided with a conducting wire which is respectively connected with the stainless iron base and the silver sheet assembly. The base, the two metal sheets and the movable contacts of the temperature protector respectively adopt a welding structure, so that the current conduction performance of the temperature protector is enhanced, the inner resistance is effectively reduced, and the size is reduced; and the movable contacts are directly welded onto the two metal sheets, and the two metal sheets play a dual role in protecting the temperature and current, so that the effect speed of the temperature protector can be improved.
Description
[technical field]
The utility model relates to a kind of current mode temperature protector.
[background technology]
The bimetal leaf temperature protector of using at present mainly comprises base, silver strip assembly, bimetal leaf, movable contact spring, moving contact, shell etc.Adopt riveting technology, said modules is riveted into as a whole, 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: existing temperature protector is for only playing response to temperature, do not have a protective effect to electric current is excessive.
[summary of the invention]
For solving the problems of the technologies described above, the utility model provides a kind of current mode temperature protector simple in structure, easy to use, and Stability Analysis of Structures plays double protection to temperature and electric current.
The current mode temperature protector of the utility model comprises shell, and the inner bottom of said shell is provided with the stainless iron base; It is L shaped folding shape structure that the right-hand member of stainless iron base is bent into cross section to the top; Be provided with the silver strip assembly near the left end place on the stainless iron base, the top, right side of silver strip assembly is provided with bimetal leaf, and the right portions of bimetal leaf is welded on the left bottom of folding shape structure; The left end bottom of bimetal leaf is provided with moving contact; Moving contact is resisted against on the silver strip assembly, and through the sealing device sealing, the left side of sealing device is provided with respectively the lead that is connected with the silver strip assembly with the stainless iron base in the left side shell of silver strip assembly.
The current mode temperature protector of the utility model, said shell are iron or heat-resisting plastic shell.
The current mode temperature protector of the utility model, said sealing device are the sealant layer that is arranged in the left side shell of silver strip assembly, and two leads pass sealant layer respectively and are connected with the silver strip assembly with the stainless iron base respectively.
The current mode temperature protector of the utility model, the cross section of said shell are rectangle.
Compared with prior art the beneficial effect of the utility model is: base, bimetal leaf and the moving contact of the current mode temperature protector of the utility model all adopt Welding Structure; Increased the current lead-through performance of temperature protector; Effectively reduce internal resistance, reduced volume, moving contact is welded direct on the bimetal leaf; Bimetal leaf plays double protection to temperature and electric current, has improved the effect speed of temperature protector.
[description of drawings]
Fig. 1 is the structural representation of the described current mode temperature protector of the utility model embodiment;
Fig. 2 is the vertical view of the described current mode temperature protector of the utility model embodiment.
Among the figure:
1, shell; 2, stainless iron base; 3, folding shape structure; 4, silver strip assembly; 5, bimetal leaf; 6, moving contact; 7, sealing device; 8, lead.
[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 current mode temperature protector comprises shell 1, and the inner bottom of said shell 1 is provided with stainless iron base 2; It is L shaped folding shape structure 3 that the right-hand member of stainless iron base 2 is bent into cross section to the top; Be provided with silver strip assembly 4 near the left end place on the stainless iron base 2, the top, right side of silver strip assembly 4 is provided with bimetal leaf 5, and the right portions of bimetal leaf 5 is welded on the left bottom of folding shape structure 3; The left end bottom of bimetal leaf 5 is provided with moving contact 6; Moving contact 6 is resisted against on the silver strip assembly 4, and through sealing device 7 sealings, the left side of sealing device 7 is provided with respectively the lead 8 that is connected with silver strip assembly 4 with stainless iron base 2 in the left side shell of silver strip assembly 41.
The current mode temperature protector of the utility model, said shell 1 is iron or heat-resisting plastic shell.
The current mode temperature protector of the utility model, said sealing device 7 is the sealant layer in the left side shell 1 that is arranged on silver strip assembly 4, two leads 8 pass sealant layer respectively and are connected with silver strip assembly 4 with stainless iron base 2 respectively.
The current mode temperature protector of the utility model, the cross section of said shell 1 are rectangle.
When the current mode temperature protection implement body of the utility model was worked, bimetal leaf 5 was in free state, moving contact 6 and silver strip assembly 4 closures, circuit turn-on.When electrical equipment makes temperature rise to the operating temperature of temperature protector because of heating or the electric current that passes through when generating heat operating temperature to temperature protector; Bimetal leaf 5 is heated and produces internal stress and action rapidly; Push said moving contact 6 open and leave said silver strip assembly 4 and open circuit, play a protective role thereby cut off appliances power source.When being dropped to the specified reset temperature value of said temperature protector by protection electrical equipment temperature, bimetallic element returns to the initial condition closing of contact, and electrical equipment recovers operate as normal.The moving contact 6 of the current mode temperature protector of the utility model is welded direct on the bimetal leaf 5, and 5 pairs of temperature of bimetal leaf and electric current play double protection, have improved the effect 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.
