Abstract
An insulation sheet lock type hand-operated reset protector is disclosed. The insulation sheet lock type hand-operated reset protector is a combined type overflow and overheat protector. The insulation sheet lock type hand-operated reset protector comprises a shell body, wherein a first wire connection sheet and a second wire connection sheet are arranged in the shell body and are respectively connected on the shell body in a riveted manner, the outer ends of the first wire connection sheet and the second wire connection sheet are arranged outside the shell body, the position of the second wire connection sheet is lower than the position of the first wire connection sheet, a bimetallic sheet is fixedly connected above the inner end of the first wire connection sheet, the inner end of the second wire connection sheet is provided with a stationary contact point, the free end of the bimetallic sheet is provided with a moving contact point, the stationary contact point contacts and cooperates with the moving contact point, a push rod is arranged in the shell body, the inner end of the push rod is connected with an insulation sheet, and a reset spring is arranged between the push rod and the shell body. When the protector is switched off, the insulation sheet is arranged between the stationary contact point and the moving contact point; when the protector is reset, the insulation sheet leaves the stationary contact point and moving contact point and is positioned in the direction toward which the reset spring is compressed. The reset protector is characterized by simple structure, convenience of use, and high safety coefficient.
Description
Technical field
The utility model belongs to a kind of composite overflow and overheat protector, particularly overheated overcurrent protector and the temperature control control device thereof such as the electric rotating machine of a kind of generator, motor, household electrical appliance, electric, electrical heated appliance, ligthing paraphernalia, communication apparatus, instrument.
Background technology
Current protector on the market mostly is and automatically resets.Be not easy to the client applies under different environment.The auto-reset type products characteristics is the temperature of load is kept within the specific limits; can be because of load rear temperature permanent not the shielding that sharply raise of breaking down; once load temperature is down in certain limit; protector meeting automatic reclosing; and the fault of load is not resolved at all, increased virtually application risk.
The utility model content
It is a kind of simple in structure, easy to use that the utility model provides, the insulating trip locking-type Manual reset protector that coefficient of safety is high.
The utility model comprises housing, arrange first in described housing, the second lug plate, described first, the second lug plate is riveted on respectively on described housing, described first, the outer end of the second lug plate is arranged on outside described housing, the position of described the second lug plate is lower than described the first lug plate, be fixedly connected with a bimetal leaf above described first lug plate the inner, one fixed contact is set on the inner of described the second lug plate, free end at described bimetal leaf arranges a moving contact, described fixed contact, fixed contact is in contact with one another cooperation, one push rod is set in described housing, one end of described push rod is arranged on outside described housing, the other end of described push rod connects an insulating trip, between described push rod and described housing, a back-moving spring is set, one end of described back-moving spring is fixedly connected on the interior top of described push rod, the other end of described back-moving spring is fixed on described housing madial wall, when protector disconnects, described insulating trip is arranged between described fixed contact and described moving contact, and when protector resets, described insulating trip leaves described fixed contact, moving contact and is positioned at the direction of back-moving spring compression.
During the utility model work, fixed contact, moving contact are in contact with one another, the reset protector device is in conducting state,, if overcurrent, superheating phenomenon occur, bimetal leaf is heated and distortion occurs, it drives moving contact and opens fixed contact, and now insulating trip, push rod are by recoil of spring, and insulating trip moves between fixed contact and moving contact both isolation, reach so better protection, safer; When reset protector resets, by push rod, depress insulating trip, insulation board leaves dynamic and static contact; the contact of dynamic and static contact reaches conducting state; this by hand-reset, make protector simpler, its need determine that the operating temperature of protector is without definite its reset temperature.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
The A-A that Fig. 2 is Fig. 1 is to view.
Embodiment
As Fig. 1, shown in 2, this reset protector comprises housing 1, arrange first housing 1 is interior, the second lug plate 2, 3, first, the second lug plate 2, 3 are riveted on respectively on housing 1, first, the second lug plate 2, 3 outer end is arranged on outside housing 1, the position of the second lug plate 3 is lower than the first lug plate 2, be fixedly connected with a bimetal leaf 4 above first lug plate 2 the inners, one fixed contact 5 is set on the inner of the second lug plate 3, free end at bimetal leaf 4 arranges a moving contact 6, fixed contact 5, moving contact 6 is in contact with one another cooperation, at the interior push rod 7 that arranges of housing 1, one end of push rod 7 is arranged on outside housing 1, the other end of push rod 7 connects an insulating trip 8, one back-moving spring 9 is set between push rod 7 and described housing 1, one end of back-moving spring 9 is fixedly connected on the interior top of push rod 7, the other end of back-moving spring 9 is fixed on housing 1 madial wall, when protector disconnects, insulating trip 8 is arranged between fixed contact 5 and described moving contact 6, and when protector resets, insulating trip 8 leaves described fixed contact 5, moving contact 6 and is positioned at the direction of back-moving spring compression.
