Abstract
The utility model relates to a disk motor protector, which comprises a housing. A cooper base is arranged in the internal bottom of the housing, and a movable reed is arranged on the copper base in a position close to the right end of the copper base, wherein one end of the movable reed is welded on the copper base, and the other end of the movable reed abuts against a silver strip assembly; double round metal strips are arranged under the movable reed, wherein the double round metal strips are fixed on a positioning boss of the copper base; the left end of the copper base and the right end of the silver strip assembly are respectively connected with two leads; and the left end of the housing is equipped with a sealing cover. According to the disk motor protector of the utility model, the double metal strips adopt disk structures, wherein the diameter of a metal strip is less than the width of the base so that the metal strip is not locked by the housing, the metal strips are regularly disk-shaped and the radian thereof is uniform, and the temperature is stable and the temperature responding speed is fast.
Description
[technical field]
The utility model relates to a kind of motor temperature protector, relates in particular to a kind of disk motor protector.
[background technology]
The round dual sheet metal temperature protector of using at present mainly comprises base, silver strip assembly, round dual sheet metal, movable contact spring, moving contact, shell etc.Adopt riveting technology, said modules is riveted into as a whole, the round dual sheet metal side of being sheet, 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 the round dual sheet metal; The round dual sheet metal 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 round dual sheet metal temperature protector: employing side's chip architecture in the existing structure, round dual sheet metal radian is inhomogeneous, produces the bad phenomenon of temperature drift and card.
[summary of the invention]
For solving the problems of the technologies described above, the utility model provides a kind of disk motor protector simple in structure, easy to use, synthetic operation stable performance.
The disk motor protector of the utility model comprises shell, and the inner bottom of said shell is provided with copper base; Be provided with movable contact spring near the right-hand member place on the copper base; One end of movable contact spring is welded on the copper base, and the moving contact of the other end of movable contact spring is resisted against on the silver strip assembly, and the movable contact spring below is provided with the round dual sheet metal on the positioning boss that is fixed on copper base; The right-hand member of the left end of copper base and silver strip assembly connects lead respectively, and the left end of shell is provided with seal cover.
The disk motor protector of the utility model, said shell are iron or heat-resisting plastic shell.
The disk motor protector of the utility model, through the sealant layer sealing, two leads pass seal cover successively with sealant layer and be connected with the silver strip assembly with copper base respectively in the cavity between said silver strip assembly and the seal cover.
The disk motor protector of the utility model, the diameter of said round dual sheet metal is less than the width of copper base.
The disk motor 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: the bimetal leaf of the disk motor protector of the utility model adopts wafer architecture, and diameter can not block with shell less than the base width; The disk shape of rule, radian is even, temperature stabilization; Temperature response speed is fast.
[description of drawings]
Fig. 1 is the structural representation of the described disk motor protector of the utility model embodiment;
Fig. 2 is the vertical view of the described disk motor protector of the utility model embodiment.
Among the figure:
1, shell; 2, copper base; 3, movable contact spring; 4, silver strip assembly; 5, positioning boss; 6, round dual sheet metal; 7, lead; 8, seal cover; 9, sealant layer; 10, moving contact.
[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.
As shown in Figure 1; A kind of disk motor protector comprises shell 1, and the inner bottom of said shell 1 is provided with copper base 2; Be provided with movable contact spring 3 near the right-hand member place on the copper base 2; One end of movable contact spring 3 is welded on the copper base 2, and the moving contact 10 of the other end of movable contact spring 3 is resisted against on the silver strip assembly 4, and movable contact spring 3 belows are provided with the round dual sheet metal 6 on the positioning boss 5 that is fixed on copper base 2; The right-hand member of the left end of copper base 2 and silver strip assembly 4 connects lead 7 respectively, and the left end of shell 1 is provided with seal cover 8.
The disk motor protector of the utility model, said shell 1 is iron or heat-resisting plastic shell.
The disk motor protector of the utility model, through sealant layer 9 sealings, two leads 7 pass seal cover 8 successively with sealant layer 9 and be connected with silver strip assembly 4 with copper base 2 respectively in the cavity between said silver strip assembly 4 and the seal cover 8.
The disk motor protector of the utility model, the diameter of said round dual sheet metal 6 is less than the width of copper base 2.Therefore round dual sheet metal 6 can not blocked by shell 1, has improved the temperature response speed of temperature protector.
The disk motor protector of the utility model, the cross section of said shell 1 are rectangle.
When the disk motor protector of the utility model was specifically worked, round dual sheet metal 6 was in free state, moving contact 10 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; Said shell 1 is heated and conducts to round dual sheet metal 6; Round dual sheet metal 6 is heated and produces internal stress and action rapidly; Push said moving contact 10 open and leave 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, round dual sheet metal 6 returns to the initial condition closing of contact, and electrical equipment recovers operate as normal, has improved the temperature 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.
