Background technology
In prior art, overheat protector adopts the design of bimetal leaf overcurrent more; because the little bimetal leaf current effect that causes of volume is larger; so all can produce the unreliable phenomenon of protection temperature; though have indivedual thermal protector producer to have the not overcurrent design of the bimetallic of employing, unreasonablely cause thermal protector to have noise and be unfavorable for the problems such as high efficiency production because designing.
Summary of the invention
The utility model object is to provide a kind of miniature double-metal sheet type overheat protector for above-mentioned weak point, and this Miniature bimetallic strip heat protector product structure design is reasonable, and current effect is little; temperature control is accurate; be applicable to automated production, and noiselessness, stable and reliable product quality.
Miniature double-metal sheet type overheat protector is to take following technical scheme to realize:
Miniature double-metal sheet type overheat protector comprises shell, lower terminal, moving contact, fixed contact, bimetallic element, elastic conducting strip, upper terminal, holder, fluid sealant and wire; One end of upper terminal is provided with wire bonds locating detent, the other end is provided with elastic conducting strip and connects boss, one end of lower terminal is provided with wire bonds locating detent, middle-end is provided with holder clamping ring, the other end is provided with fixed contact, on the wire bonds locating detent that the wire bonds locating detent that one end of upper terminal arranges and one end of lower terminal arrange, be welded with respectively wire, upper terminal, lower terminal be placed in to plastic mould injection simultaneously and be processed to form holder assembly; Bimetallic element is placed in to the groove of holder; bimetallic element has the borehole jack of nose end to connect on boss at the elastic conducting strip of upper terminal; again the elastic conducting strip that is provided with moving contact is placed in to bimetallic element top; and the elastic conducting strip that the elastic conducting strip other end is provided with upper terminal is connected after boss connects and formed thermal protector assembly, thermal protector assembly is put after shell and fixed with fluid sealant.
One end of described holder is provided with bimetallic element upset boss.
Described bimetallic element is provided with bimetallic element upset circle stress and bimetallic element slow-action district discharges C type groove.
The holder clamping ring of the middle-end setting of described lower terminal has one at least.
Bimetallic element is provided with groove surface (high expanding noodles) and convex surface (low bulk face), and bimetallic element can be manufactured normally closed product downwards by groove surface (high expanding noodles), and product is often opened in the manufacture downwards of convex surface (low bulk face) that also can bimetallic element.
Miniature double-metal sheet type overheat protector operation principle:
When protected electric component abnormal temperature is too high; when the bimetallic element of miniature double-metal sheet type overheat protector is experienced prefabricated temperature and rapidly reversion is pushed spring leaf open and is made moving contact and fixed contact disconnection; protected electric component main circuit disconnects rapidly and avoids damaging; when temperature drops to the reset temperature of bimetallic element; bimetallic element recovers upset; the moving contact of miniature double-metal sheet type overheat protector and fixed contact closure, reclosed the main circuit of protected electric component and recovered normal operating conditions.
Miniature double-metal sheet type overheat protector is reasonable in design, and compact conformation is a kind of pure temperature mode, and temperature control is accurate, and noiselessness, and volume miniaturization is applicable to the overheat protector of automated production.This Miniature bimetallic strip heat protector product structure design is reasonable, and current effect is little, and noiselessness stable and reliable product quality.
