Through adopting the above-mentioned, make circuit breaker inner structure reasonable, wherein form a more confined space through extending limit and well seat with perpendicular groove on the base and place N utmost point contact device's wire, be provided with the arrangement groove independently in the top that extends the limit, it also forms more independent space by the hypotenuse cover of well seat and places L utmost point contact device to place the groove top, N utmost point contact device's wire just is fine just separated with the wire of L utmost point contact device like this, also can not receive the ignition of electric arc and metal ion in addition, greatly increased the security of product, the shutoff that appears above does not mean sealed, but means the meaning of cutting off.

The invention further provides that: a straight edge is arranged on one side of the bevel edge on the second end of the middle seat, the straight edge and the bevel edge are integrally arranged, a channel is arranged between the arc extinguish chamber mounting area on the middle seat and the straight edge, and openings for electric arcs to run out are arranged at the upper end and the lower end of the channel; and a lead of the L-pole contact device is bent towards the upper cover at an opening at the upper end of the channel and then is connected with a release coil of the circuit breaker, and a supporting sheet is arranged on one side of the extending edge, which is positioned on the base.

Through adopting above-mentioned scheme, through the setting of straight flange, can make like this and form a passageway between circuit breaker explosion chamber rear end and the straight flange, electric arc will run from top to bottom along the passageway direction like this, can not get into other positions, increases product security, and the setting of backing sheet can the fixed bolster promptly, also has to shelter from to the wire top of N utmost point contact device in addition, prevents that electric arc from getting into.

The present invention will be further described with reference to the following examples.
