For achieving the above object, the utility model provides following technical scheme: the moving contact rack in a kind of breaker of plastic casing, be arranged in Shell of circuit breaker, comprise rack body, described rack body offers the screwed hole be connected with Shell of circuit breaker, described support is provided with the support sector be connected with moving contact, described support sector offers hinge hole, wherein: described rack body is provided with boss, described screwed hole runs through described boss.
By adopting technique scheme, utilize the boss set up on rack body, thickeied the hole depth of screwed hole, added the length of screw thread in screwed hole, make the connection between rack body and Shell of circuit breaker more firm, stable, effectively improve the useful life between contact.
The utility model is set to further: described boss and rack body are wholely set.
By adopting technique scheme, boss and being wholely set of rack body make the processing of boss more simple and convenient simultaneously, and the seamless link simultaneously between boss and rack body makes support more durable.
The utility model is set to further: described boss is arranged on the one side of rack body towards hinge hole.
By adopting technique scheme, avoiding boss to be clipped between frame member body and Shell of circuit breaker and causing supporter fixing-stable.
The utility model is set to further: screwed hole is arranged on the side of the vertical center line of hinge hole.
By adopting technique scheme, moving contact and screwed hole are separately positioned on the both sides of hinge hole, and the power making supporter bear when moving contact moves is more even, increases the useful life of supporter.
The utility model is set to further: the distance of the hole wall distance bracket body edges of described screwed hole is more than or equal to the diameter of screwed hole.
By adopting technique scheme, ensure that the intensity of described screwed hole, further increasing the useful life of supporter.
The utility model is set to further: described support sector is vertical with rack body to be arranged, and the junction of described support sector and rack body is provided with back-shaped kink.
Further: described back-shaped kink comprises vertical portion, horizontal part, and described vertical portion is connected with rack body, the vertical connecting portion, one end of described horizontal part, the other end connects support sector.
Further: to be provided with rake between described vertical portion and horizontal part, described vertical portion is connected by described rake with horizontal part.
By adopting technique scheme, back-shaped kink strengthens the intensity of support sector, rake is while strengthening support sector's intensity further simultaneously, effectively can also reduce space in the Shell of circuit breaker shared by supporter, facilitate installation and the use of supporter.
