Abstract
The utility model relates to the manufacturing technical field of an overheating and overcurrent protection device and a temperature control device thereof, in particular to an automatic calibration type overheating and overcurrent power-off protection device. The automatic calibration type overheating and overcurrent power-off protection device comprises an outer shell, wherein one end of the outer shell is provided with a lead, and a bracket and a fixed base are arranged between the lead and the bottom part of an inner cavity of the outer shell; one end of the bracket, which is close to the bottom part of the outer shell, is integrally provided with a limiting baffle block, and the upper surface of the bracket is integrally provided with a calibration boss; a bimetallic strip is connected above the bracket through a screw, the lower surface of the bimetallic strip is in contact with the calibration boss, one end of the bimetallic strip is in contact with the limiting baffle block, the upper surface of the other end is provided with a moving contact, a static contact plate calibration frame is arranged on the fixed base, the lower surface of the static contact plate calibration frame is provided with a static contact, and the moving contact and the static contact are arranged in a contactable manner; and epoxy resin is arranged between the fixed seat and the lead. The automatic calibration type overheating and overcurrent power-off protection device has overheating and overcurrent duplicate protection, the internal resistance and temperature of the product are more stable due to the riveted structure, and the automatic calibration of the product can be realized by the calibration boss.
Description
Technical field
The utility model relates to the manufacturing technology field of overheated overcurrent protector and temperature control control device thereof.
Background technology
The structure of protector on the market is more outmoded at present, and the temperature typing relies on fully and manually finishes, and namely the manual angle that changes the bimetallic element weld makes bimetal leaf produce deformation, thereby reaches the effect of temperature typing.The shortcoming of manual temperature typing is that efficient is low, temperature discrete.Manufacture difficulty and cost have been increased substantially.
Summary of the invention
The utility model purpose is to provide at above defective a kind of overheated overcurrent power-off protector of automatic calibration type of mechanical automation temperature typing.
The utility model comprises shell, at described shell one end lead is set, and between described lead and shell inner cavity bottom support, holder is set, and described support is fixedly connected on the case body, and described holder is arranged on the support top and is connected with case body; End disjunctor at the close outer casing bottom of described support arranges positive stop, at described rack upper surface disjunctor the calibration boss is set; Above described support, connect bimetal leaf by screw, the lower surface of described bimetal leaf contacts with the calibration boss, one end of described bimetal leaf contacts with positive stop, upper surface at the other end arranges moving contact, at described holder the static contact calibrated mount is set, lower surface at described static contact calibrated mount arranges static contact, but described moving contact and the setting of static contact contact; Between described holder and lead, epoxy resin is set.
The utility model can change original manual temperature typing the typing of into mechanical automation temperature.Principle is for placing product the environment of specified break-off signal, the machinery thimble makes bimetal leaf produce deformation gradually, in case the bimetal leaf rotary movement by servomotor compressing calibration boss, signal element can collect power-off signal, and this moment, the temperature type-approval process was finished.Mechanical automation temperature typing efficient height, temperature Centralized.The utility model can overheated overcurrent duplicate protection, and riveted construction makes product internal resistance and temperature more stable, and the calibration boss can realize that product calibrates automatically.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises shell 1, at shell 1 one ends lead 2 is set, and between lead 2 and shell 1 intracavity bottom support 3, holder 4 is set, support 3 is fixedly connected on shell 1 housing, and holder 4 is arranged on support 3 tops and is connected with shell 1 housing; End disjunctor in support 3 close shell 1 bottoms arranges positive stop 3-2, at support 3 upper surface disjunctors calibration boss 3-1 is set; Above support 3, connect bimetal leaf 7 by screw, the lower surface of bimetal leaf 7 contacts with calibration boss 3-1, one end of bimetal leaf 7 contacts with positive stop 3-2, upper surface at the other end arranges moving contact 8, at holder 4 static contact calibrated mount 9 is set, lower surface at static contact calibrated mount 9 arranges static contact 10, but moving contact 8 and static contact 10 contact settings; Between holder 4 and lead 2, epoxy resin 11 is set.
