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
The Reed lock fixed pattern Manual reset protector that provides a kind of coefficient simple in structure, easy to use, safe high is provided the utility model purpose.
The utility model comprises housing, first " L " shape lug plate is set in described housing, second " L " shape lug plate, described first, the outer end of second " L " shape lug plate is separately positioned on described hull outside, describedly be arranged on first in housing, the built-in lamellar body of second " L " shape lug plate is arranged horizontally, the built-in lamellar body of described second " L " shape lug plate is higher than described first " L " shape lug plate, top at the built-in lamellar body of described first " L " shape lug plate arranges fixed contact, one bimetal leaf is set above described fixed contact, one moving contact is set on described bimetal leaf, described moving contact is in contact with one another and coordinates with described fixed contact, in the left side of described bimetal leaf, one spring leaf is set, the left end end of described spring leaf is fixed on described housing, the right part of described spring leaf is arranged on the below of described bimetal leaf and conflicts at the left end of described bimetal leaf, described spring leaf keeps the bowed state of arch, the right-hand member of described bimetal leaf is connected with the built-in lamellar body contact of described second " L " shape lug plate, one push rod is set above described bimetal leaf, on the described housing corresponding with push rod, the installation through hole is set, the upper end of described push rod is arranged on outside described housing through through hole is installed, conflict above described bimetal leaf in the lower end of described push rod, be provided for the flexible restoring organ that this reset protector is opened or disconnected on described push rod.
During the utility model work, if produce overcurrent, overheated situation, spring leaf is subject to the impact of temperature that the phenomenon that heat rises occurs, bimetal leaf is upspring, now fixed contact and moving contact separately, so play the effect of overcurrent protection, after circuit recovers, by manually pressing lower push-rod, can recover the connected state of reset protector; This reset protector is simple in structure, and hand-reset is easy to operate, and it only needs to determine its operating temperature without the reset temperature of considering protector, makes the uncertain factor of protector reduce, and safety improves.
Flexible restoring organ described in the utility model comprises spring, one position-limited rack is set on described housing, the body of rod that one section diameter is less than top is arranged in the bottom of described push rod, described spring is nested with on the body of rod of described minor diameter, the body of rod of described minor diameter and its top, the push rod body of below forms limited step, one through hole is set on the lower wall of described position-limited rack, the body of rod of described minor diameter freely is set in described through hole, conflict on the lower surface of described position-limited rack in the upper end of described spring, on the limited step of conflicting below the described minor diameter body of rod in the lower end of described spring, the hand-reset mode of this structure, rational in infrastructure, simple, easy to operate.
