Description
Technical field
The utility model relates to a kind of protector, particularly a kind of heat protector of motor.
Background technology
Motor refers to a kind of calutron of realizing electric energy conversion or transmit according to the law of electromagnetic induction, and its Main Function is to produce driving torque, as the power source of electrical equipment or various machineries.
Motor is in running, if there is clamping stagnation, although the power output shaft of its motor stops the rotation, but its internal component is still in implementation, and energy cannot be released, cause the electric current of motor internal excessive, excess Temperature, light reduce useful life of motor internal components and parts, heavy motor internal components and parts are burnt out, cause motor to use.
Summary of the invention
The deficiency existing for prior art, the utility model provides a kind of simple in structure, easy accessibility, when current of electric is excessive and excess Temperature can cut off the heat protector of motor of motor power.
For achieving the above object, the utility model provides following technical scheme: a kind of heat protector of motor, it is characterized in that: the lid that includes base plate and can fasten with base plate, on base plate and lid, be respectively equipped with binding post, between base plate and lid, be provided with insulator; Described base plate includes two noseplates that connect by electric-conductor and rear base plate, after described base plate and lid fasten, between base plate and lid, form installation cavity, rear base plate is provided with fixed contact, and lid is provided with in installation cavity and can contacts or separate and raise or reduce the moving contact that deformation occurs with temperature by fixed contact.
Adopt technique scheme; binding post on base plate and lid respectively with the internal circuit conducting of motor; form loop; in use; moving contact and fixed contact are contact condition; when the electric current of motor internal excessive; while causing temperature to raise; the heating of electric-conductor in installation cavity, moving contact is with the rising generation deformation of temperature, and separates between fixed contact; the power supply of motor is disconnected; while preventing that clamping stagnation from appearring in motor, inner excess Temperature and cause burning out, has good protective effect to the motor feels hot.
The utility model is further set to: the shirt rim of lid on the edge of base plate one end, the clamping block that base plate is provided with perpendicular setting and can fastens with the shirt rim of lid, described electric-conductor is one end and noseplate welding, the heating wire of the other end and the welding of rear base plate.
Adopt technique scheme, the structure making after lid and base plate fasten is set so more firm, prevent that lid and base plate from getting loose.
The utility model is further set to: moving contact includes one end and lid is articulated and connected, the bimetal leaf that the other end is movable end, and the movable end place of bimetal leaf is provided with the contact that can contact with fixed contact conducting.
Adopt technique scheme, arrange so cheap, install and easy to use, simple in structure.
Below in conjunction with accompanying drawing, the utility model is further described.
Brief description of the drawings
Fig. 1 is the schematic perspective view of the utility model embodiment;
Fig. 2 is the schematic perspective view of lid in the utility model embodiment;
Fig. 3 is the decomposing schematic representation of the utility model embodiment.
Embodiment
A kind of heat protector of motor as shown in Fig. 1-Fig. 3, the lid 2 that includes base plate 1 and can fasten with base plate 1, on base plate 1 and lid 2, be respectively equipped with binding post 3, between base plate 1 and lid 2, be provided with insulator 4,4 of this insulators are arranged in the insulation scraps of paper between base plate 1 and lid 2, select the insulation scraps of paper as insulator 4, not only cheap, and also easy for installation; Base plate 1 includes two noseplates that connect by electric-conductor 5 11 and rear base plate 12, after base plate 1 fastens with lid 2, between base plate 1 and lid 2, form installation cavity, rear base plate 12 is provided with fixed contact 6, and lid 2 is provided with in installation cavity and can contacts or separate and raise or reduce the moving contact 7 that deformation occurs with temperature by fixed contact 6.In such scheme; binding post 3 on base plate 1 and lid 2 respectively with the internal circuit conducting of motor; form loop; in use; moving contact 7 is contact condition with fixed contact 6; when the electric current of motor internal excessive; while causing temperature to raise; electric-conductor 5 in installation cavity generates heat, and moving contact 7 is with the rising generation deformation of temperature, and separates between fixed contact 6; the power supply of motor is disconnected; while preventing that clamping stagnation from appearring in motor, inner excess Temperature and cause burning out, has good protective effect to the motor feels hot.
In the utility model embodiment, in order to make can stable enforcement to be connected between lid 2 and base plate 1, prevent from getting loose after lid 2 and base plate 1 from fastening, the shirt rim 21 of lid 2 on the edge of base plate 1 one end, the clamping block 13 that base plate 1 is provided with perpendicular setting and can fastens with the shirt rim of lid 2 21.Certainly, it should be noted that, also can adopt trip bolt or rivet to implement to be connected between base plate 1 and lid 2, is all feasible.Electric-conductor 5 in the utility model embodiment is for one end and noseplate 11 weld, the heating wire that the other end and rear base plate 12 weld, and this heating wire is copper wire.
In the utility model embodiment, in order to reduce production costs, simultaneously convenient for assembly, moving contact 7 includes one end and lid 2 is articulated and connected, the other end is the bimetal leaf of movable end, and the movable end place of bimetal leaf is provided with the contact 71 that can contact with fixed contact 6 conducting.Bimetal leaf can variation with temperature generation deformation, and in the time that the temperature in motor raises, the contact 71 on bimetal leaf separates with fixed contact 6, after temperature reduces, bimetal leaf is replied initial condition, and the contact 71 on it contacts with fixed contact 6, makes the circuit turn-on of motor.
