Electric appliance is used by excess, and safety allowance is inadequate.To which that there are performances is unstable, service life is short, structure is multiple for the D.C. contactor
Miscellaneous, bulky defect.
Summary of the invention
The purpose of the utility model is to overcome the defect of the prior art, provide a kind of structure it is simple, it is stable and reliable for performance,
Long service life, D.C. contactor small in size.
To achieve the above object, the utility model uses a kind of D.C. contactor, including shell, electromagnetic mechanism, contact system
System, arc quenching system, the contact system include the contact rack being arranged with the linkage of the push rod of electromagnetic mechanism, are arranged on contact rack
Moving contact, be arranged between moving contact and contact rack pressure spring, corresponding moving contact both ends to be separately positioned on shell intracorporal
Two static contacts, the both ends of the moving contact respectively upward bending and constitute have contact portion, be provided on the contact portion
The movable contact matched with each static contact is respectively arranged with the stationary contact matched with movable contact on two static contacts,
The arc quenching system includes being separately positioned on the intracorporal two arc extinguishing components of shell, the arc extinguishing group at corresponding two static contacts
Part includes being arranged at the side that the intracorporal arc-extinguish chamber of shell, corresponding static contact are arranged at corresponding static contact in the intracorporal magnetic blow-out group of shell
One end of part, the first arc leading angle, the second arc leading angle, first arc leading angle extends in the grid in arc-extinguish chamber, and first draws
The contact portion of the other end of arc angle towards moving contact extends, and one end of second arc leading angle extends in the grid of arc-extinguish chamber
Interior, the other end of the second arc leading angle is connected on static contact, and it is logical that striking is formed between the first arc leading angle and the second arc leading angle
Road.
The beneficial effect of above structure is: the moving contact of the D.C. contactor is designed using bridge-type double contact structure, moves touching
Point is arranged on the contact portion of bending setting of moving contact, to reduce the space that contact system occupies, is conducive to increase dynamic
Opening away from enough open divides arc ability away from can enhance the contactor, is conducive to extend the contactor between contact and stationary contact
Service life.To which the contactor has the advantages that simple structure, stable and reliable for performance, long service life, small in size.
Particularly, the upper end of the push rod has the T-shaped clamping portion of cross sectional shape, is provided on the contact rack
The T-slot matched with clamping portion, the clamping portion are fastened in T-slot and constitute being linked for contact rack and push rod.
Push rod is connect by the way of being engaged by clamping with contact rack, convenient for the assembly of contact rack and push rod, is conducive to improve the contactor
Assembly efficiency.
