Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of temperature protector comprises shell 1 and static contact 2, and described static contact 2 is installed in shell 1 one ends, and static contact 2 is positioned at a section 21 of enclosure and is provided with fixed contact 211; Described shell 1 another end is equipped with movable contact spring 3, and movable contact spring 3 is positioned at a section of enclosure and is provided with the moving contact 311 that matches with the fixed contact 211 of static contact; Described shell 1 upside is equipped with thermometer 4, and this thermometer 4 is corresponding up and down with the position of one section movable contact spring 31 of enclosure, be provided with actuating strut 5 between this thermometer 4 and the movable contact spring 3, and this actuating strut 5 can be up and down along a through hole 6 of shell 1 shell wall.
Such as Fig. 1, Fig. 2 and shown in Figure 3, described shell 1 comprises metal cover body 11, insulation upper casing 12 and insulation lower casing 13, described metal cover body 11 is fixed in metal cover body 11 inside by will insulate upper casing 12 and the lower casing 13 that insulate of its bottom inferior horn of bending, and static contact 2 and movable contact spring 3 are fixed between insulation upper casing 12 and the insulation lower casing 13, thereby synthetic integral body.
As shown in Figure 3, described thermometer 4 is by being fixedly welded on the metal cover body 11, and, be higher than side on the metal cover body 11 among the described thermometer 4.As the optimal way that is welded and fixed, the edge of described thermometer 4 is fixedly welded on the metal cover body 11.
As shown in Figure 3, described static contact 2 is positioned at a section 21 of enclosure and is attached at side under the insulation upper casing 12, and described movable contact spring 3 is positioned at one section 31 elasticity perk side on insulation lower casing 13 of enclosure; In described shell 1 inside, described fixed contact 211 is arranged at the end of static contact, and described moving contact 311 is arranged at the end of movable contact spring.
As the optimal way of temperature protector, in technique scheme, described fixed contact 211 and moving contact 311 are silver contact.
During this temperature protector specific works, thermometer 4 is in free state, and the moving contact 311 of movable contact spring 3 contacts closed with the fixed contact 211 of static contact 2, circuit turn-on.When electrical equipment makes temperature rise to the operating temperature of temperature protector because of heating or the current heating that passes through during to the operating temperature of temperature protector; described thermometer 4 is heated and produces internal stress and rapidly action; make that actuating strut 5 is stressed pushes movable contact spring 3 open; thereby make the moving contact 311 of movable contact spring 3 and the fixed contact 211 of static contact 2 separately cause circuit to disconnect, play a protective role thereby cut off appliances power source.When protected electrical equipment drop in temperature arrived the specified reset temperature value of described temperature protector, the moving contact 311 of movable contact spring 3 and the fixed contact 211 of static contact 2 returned to the first closure state, and electrical equipment recovers normal operation; The high clever sensitivity temperature sheet 4 that this temperature protector adopts directly be fixed on the shell 1 preferential contact with electrical equipment conductor or the external world and lifting/lowering temperature speed very fast, reduce to a great extent the time that electric current is connected, reached energy-saving prevention dry combustion method effect so effectively reduced the electrical equipment power consumption; Simultaneously actuating strut 5 is placed between thermometer 4 and the movable contact spring 3, effectively avoids suppressing direct puncture product.
The above only is the utility model preferred embodiments, and every any trickle modification, equivalent variations and modification of above execution mode being done according to the technical solution of the utility model all belongs in the scope of technical solutions of the utility model.
