Constitute a right angled triangle；This inserting groove 232 is when assembling insulation board 4, and it is more convenient to assemble, insulation board 4
More stable with inserting groove 232 grafting.
As illustrated in figures 4-5, mounting groove 231 is plugged with insulation board 4 by described inserting groove 232, described absolutely
Listrium 4 plate body one end is provided with the arc opening 41 matched with dynamic contact mechanism rotating shaft, described insulation board 4 plate
The grafting boss 42 mated with described inserting groove 232 it is provided with on body plug side.
In the production process of circuit breaker base, owing to base body uses injection mo(u)lding, the thickness of dividing plate 23
Less than 4mm, and only thick than insulation board 4 1mm of the thickness of dividing plate 23, dividing plate 23 can slotted section in other words
(other parts of dividing plate have other to assemble needs, such as the present embodiment median septum to only thick than insulation board 4 1mm of thickness
Installing rack that the both sides of 23 slotted sections need to accommodate dynamic contact mechanism rotating shaft and the company being connected with operating mechanism
Bar), as insulation board 4 uses bonding or screw fastening mode to be fixed with installing port 231, assembly difficulty
Greatly, during assembling, easily damage dividing plate 23, cause base to scrap or have a strong impact on service life；Grafting
The mode being fixed, preparatory process is simple, and operation easier is low, convenient disassembly, and to dividing plate 23 without appointing
What damage；Because the thickness difference of dividing plate 23 and insulation board 4 is minimum, so using general slot can cause wall thickness
Cross thin, by size limitations so that dividing plate 23 part is high in technological requirement, and it is qualified to have a strong impact on product
Rate；The cross section (i.e. cross section on plug-in mounting mouth direction) of the notch of the inserting groove 232 on dividing plate 23 is constituted three
Dihedral, this inserting groove 232 is not size-limited when fluting, and fitting insulating panels 4 structure operation is convenient,
Reduce the requirement to production technology, and improve the qualification rate of product, reduce production cost, further
, described triangle is right angled triangle, angle β between its two solid edges on inserting groove 232
Angle is more than 0 degree, and less than 45 degree, the assembling effect in this angular range is more excellent, it is ensured that firm with assemble,
Preferably angle β angle is 30 degree.
Installing port 231 is U-shaped mouth, arc opening 41 and bottom (the bottom circular arc in the most U-shaped of this U-shaped mouth
Portion) match, form an axis hole matched with the rotating shaft of dynamic contact mechanism so that insulation board 4 is not
Affect the effect reaching insulating protection while the rotating shaft of dynamic contact mechanism normally works；With inserting groove 232
The grafting boss 42 joined makes insulation board 4 more stable with the connection of inserting groove 232, reduces fault rate, carries
The whole service life of high chopper.
