Within the chamber, it is indoor that right chamber portion stretches to right chamber；Moving contact located at contact support on, and moving contact have stretch into left chamber and
The extension of right chamber room, is contacted with static contact by this extension and realizes circuit communication.
Wherein, left and right within the chamber is equipped with arc-extinguish chamber, and arc-extinguish chamber is used for eliminating the electricity producing when dynamic and static contact separates
Arc.
The setting of arc-extinguish chamber, is conducive to the elimination of electric arc.
Wherein, left static contact has the terminals sub-portion stretched out by Shell of circuit breaker side wall.
This kind of structure is easy to left static contact wiring.
Wherein, left shell and right shell body all offer left mounting groove and right mounting groove, left mounting groove is located at left chamber
Above room, right mounting groove is located above right chamber room, and, in left mounting groove, right static contact part is located at right peace for left static contact part
In tankage.
This kind of structure, is easy to left static contact and the installation of right static contact.
Wherein, left static contact, be equipped with salient point I on right static contact, moving contact is provided with salient point II, left static contact and the right side
Contacted with salient point II using salient point I when static contact is contacted with moving contact.
This kind of structure, contacts, with salient point II, the connection realizing circuit using salient point I.
Wherein, right shell body is provided with three snap fits, and left shell is provided with the draw-in groove with snap fit cooperation；Triangular in shape point of snap fit
Cloth, one of snap fit is located near shoulder position.
Snap fit distribution triangular in shape, it is contemplated that triangle stability is higher, therefore improves left and right housing using this kind of mode
Between stability.
