Description
Technical field
The utility model relates 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
Now widely used protector great majority are temperature mode, do not possess the function of overcurrent protection; And most protectors are automatic recovery type, even for hand-reset also is mechanically to force to promote inner bimetallic element, its upset is resetted, complex operation, coefficient of safety are low.
Summary of the invention
The utility model purpose is to provide the overheated overcurrent power cut off delay of a kind of adjustable formula reset protector, and purpose is to overcome the low defective of protector complex operation, coefficient of safety of existing hand-reset.
The utility model comprises the shell body that is provided with inner chamber, one end opening of described shell body, in described shell body, holder is set, static contact, middle part at the madial wall of described shell body arranges step, one end of described holder is conflicted on described step, described static contact is set in the described holder, at described holder one mounting groove is set, one thermistor is set in described mounting groove, the lower end of described thermistor contacts with described static contact, sizing stop is set above described holder, described sizing stop riveted is on described holder, between described sizing stop and described holder, bimetallic strip is set, the sheet metal of described lower floor contacts with described thermistor, is fixedly connected with moving contact in the front portion of described sheet metal, and described moving contact is arranged on the top of described static contact, holder is stretched out in the rear end of described static contact, and the rear end of described static contact connects wire.
The utility model adopts the form of bimetal leaf overcurrent, by the obvious heating effect of electric current, plays overheated overcurrent duplicate protection; Adopt the form of calibration block riveted, temperature correction stability is strong, qualification rate is high; Adopt the form of embedded thermistor; resistance is in parallel with protector; after product disconnects; the weak current resistance of flowing through; the heat that resistance sends is supplied with protector, and it can not be automatically reset, and can automatically reset immediately after cutting off the electricity supply; thermistor plays the function that power cut off delay resets, and operation is succinct, coefficient of safety is high.
The utility model arranges the epoxy resin end socket in the rear end of described holder, sizing stop, and described epoxy resin end socket is arranged between the madial wall of the rear portion of described static contact and shell body and between the madial wall of wire and described shell body; The epoxy resin end socket plays the fixedly parts such as holder, sizing stop, simultaneously so that the stable connection of wire.
