Preferably, the tapered cap-shaped of the temp-sensing element, the temp-sensing element is by the biggish aluminium alloy of the coefficient of heat conduction
Material production.
Preferably, the release link outer sheath is equipped with pushing cover.
Preferably, an edge direction of the support chip is horizontal, and another edge direction of the support chip is from up to down along described
Pedestal box axial line gradually tapers up.
Preferably, the movable contact spring is V-arrangement elastic slice, the movable contact and the stationary contact elastic compression joint.
The beneficial effects of the utility model are:
A kind of hand-resetting temperature protector of the utility model locates temperature protector always after apparatus overheat protection
In the situation of holding, overheating protection circuit is connected by hand-reset after troubleshooting, temperature sense is sensitive, and overheating protection is dynamic
To make rapidly, accurately, control precision is high, has ensured the safe operation of equipment to greatest extent, and structure is simple, and it is easy to assembly,
High reliablity, manufacturing cost are low;When temp-sensing element is thermally deformed, push rod pushes release link to move down, at this time support chip one
While sliding in the first catching groove side, another side is squeezed to be rotated clockwise around shaft, when support chip enters the second catching groove, support
Piece revert to normal condition and locks with the second catching groove, when needing hand-reset, presses locking bar and pushing cover with hand, locking bar is first
Elastic slice is inwardly compressed, support chip rotates counterclockwise, is detached from the second catching groove, and in the case where pushing cover pushes release link movement, safety reset.
