Embodiment
As shown in Figure 1,2,3, 4, a kind of automatic reset overload protector, including lower cover 1, left lug plate 2, right lug plate 3,
Left connection sheet 4, right connection sheet 6, sheet metal 7, upper lid 11 and capping 13, the lower cover 1 is provided with left lug plate 2 and right lug plate
3, the left lower surface of lug plate 2 and left connection sheet 4 are linked together and are fixed on lower cover 1 by fixing glue 5, left connection sheet 4 with
Insulating trip lower surface is connected, under the right lower surface of lug plate 3 and right connection sheet 6 are linked together and are fixed on by fixing glue 5
On lid 1, right connection sheet 6 is connected with insulating trip upper surface, and the right upper surface of lug plate 3 and one end of sheet metal 7 pass through fixed block 8
It is fixedly connected, the movable contact 9 on the other end of sheet metal 7 is connected with the contact point 10 on left lug plate 2, upper lid 11 and lower cover
1 lower section is equipped with seal groove 12, and capping 13 is fixed in seal groove 12, and described sheet metal 7 is made up of temperature distortion material, institute
Left connection sheet 4, insulating trip and the right connection sheet 6 stated are connected and fixed by adhesive tape 14, and described left lug plate 2 and the right side connect
Through hole 15 is provided with line piece 3, some fixing holes 16 are equipped with the upper lid 11 and lower cover 1.
Because sheet metal 7 uses temperature distortion material, so the shape of sheet metal 7 can also be sent out when the temperature varies
Changing, left connection sheet 4 are connected with insulating trip lower surface, and right connection sheet 6 is connected with insulating trip upper surface, so left connection
Piece 4 and the right mutually insulated of connection sheet 6, left connection sheet 4 can also rise to left lug plate 2 and right lug plate 3 simultaneously with right connection sheet 6
To fixed effect, when electrical equipment normal work, the movable contact 9 of the left end of sheet metal 7 with contact point 10 on left lug plate 2
In closure state, when electric current becomes big or occurs short-circuit, the rise of the temperature of sheet metal 7 deforms, and sheet metal 7 upsprings
Open so that movable contact 9 separates with contact point 10 so that whole appliance circuit disconnects, and prevents electric elements from burning out, at a temperature of
Drop, sheet metal 7 are restored to the original state downwards, and movable contact 9 is contacted with contact point 10, and electrical equipment is resumed work, practical without recovering manually
It is convenient, the fixing hole 16 on upper lid 11 and lower cover 1, for upper lid 11 and lower cover 1 to be fixed together.
The utility model person of ordinary skill in the field can do various to described specific embodiment
Modification or supplement are substituted using similar mode, but without departing from spirit of the present utility model or surmount appended right will
Seek scope defined in book.
