Description
Technical field
The utility model is related to field of electronics more particularly to responsive type high current protectors.
Background technology
Protector mostly uses temperature sense protection in the prior art, though there is overcurrent protection product, because design defect leads to spirit
Sensitivity is inadequate, often will appear in use and protects blunt and generate electrical-coil burnout phenomenon.
Utility model content
The purpose of this utility model is to provide responsive type high current protectors, to solve the above technical problems.
The utility model uses following technical scheme to achieve the above object：
Responsive type high current protector, including it is static contact, movable contact spring, insulating base, movable contact, stationary contact, bimetal leaf, outer
Shell；One end of movable contact spring is provided with bending boss；Static contact and movable contact spring are molded integral by insulating base；Bimetal leaf is arranged
There is U-type groove, connected at movable contact and the U-shaped mouth of bimetal leaf, forms bimetal leaf movable contact component；Stationary contact and static contact
One end links together；Bimetal leaf movable contact component and movable contact spring link together, and form movable contact, bimetal leaf, move
Contact, static contact, stationary contact and insulation holder assembly；By movable contact, bimetal leaf, movable contact spring, static contact, stationary contact and insulating base
Component is placed in shell, is connected together by riveting, and sensitive-type high current protector is formed.
Preferably, I type tongues are provided on shell.
Compared with prior art, the utility model has the following advantages：Sensitive-type high current protector product structure design
Rationally, there is high sensitivity, be swift in response, flexible for installation, the characteristic of stable quality.It is suitable for overcurrent when electric component exception
Protection, especially suitable for wiper motor, Oil pump electrical machinery, lifting motor etc., there are overload protections.

Fig. 3 is the utility model assembled inside side structure schematic view.
Fig. 4 is the utility model overall structure diagram.
In figure：1, static contact, 2, movable contact spring, 3, insulating base, 4, movable contact, 5, stationary contact, 6, bimetal leaf, 7, shell,
8, bending boss, 9, U-type groove, 10, I type tongues.
Specific implementation mode
The utility model is further elaborated in the following with reference to the drawings and specific embodiments.
As shown in Figs 1-4, responsive type high current protector, including it is static contact 1, movable contact spring 2, insulating base 3, movable contact 4, quiet
Contact 5, bimetal leaf 6, shell 7；One end of movable contact spring 2 is provided with bending boss 8；Static contact 1 and movable contact spring 2 pass through insulating base
3 injection moldings are integral；Bimetal leaf 6 is provided with U-type groove 9, is connected at movable contact 4 and the U-shaped mouth of bimetal leaf 6, forms bimetallic
Piece movable contact component；Stationary contact 5 and 1 one end of static contact link together；Bimetal leaf movable contact component and movable contact spring 2 connect
Together, movable contact, bimetal leaf, movable contact spring, static contact, stationary contact and insulation holder assembly are formed；By movable contact, bimetallic
Piece, movable contact spring, static contact, stationary contact and insulation holder assembly are placed in shell 7, are connected together by riveting, composition sensitive-type is big
Current protector.I types tongue 10 is additionally provided on the shell 7.
The operation principle of the utility model, when protected electric component abnormal current is excessive, bimetal leaf is because of induction
High current and generate heat, inverted rapidly when the bimetal leaf of sensitive-type high current protector reaches prefabricated temperature make movable contact with it is quiet
Contact disconnects, and protected electric component main circuit is cut off the power rapidly, and temperature, which declines, after cutting off the power reaches bimetallic member
When the reset temperature of part, bimetallic element restores overturning, and movable contact and the stationary contact of sensitive-type high current protector are closed, again
Restore normal operating conditions.
The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With novel introduction, in the case where not departing from the principles of the present invention with spirit, the change that is carried out to embodiment is repaiied
Change, replace and modification is still fallen within the scope of protection of the utility model.
