It arches upward.
Separate slot is equipped between first arc striking piece and second arc striking piece.
It is equipped with boss in the shell and withholds block, second arc striking piece back is bonded with the boss, described to withhold
Block is withheld in the front end face of second arc striking piece.
Second arc striking piece bottom is equipped with inserted block, is equipped with the slot mating with the inserted block in the shell.
It further include buckle releaser and static contact, the buckle releaser includes magnetic yoke, and the magnetic yoke is equipped with salient point, the static contact
It is connect with the salient point.
The static contact is equipped with mounting groove, and the mounting groove and the salient point are engaged by clamping.
The static contact is equipped with mounting groove, and the mounting groove and salient point welding cooperate.
The beneficial effects of the utility model are: the utility model provides a kind of breaker that striking effect is good, in shell
It is opposite with arc-chutes to be equipped with the first arc striking piece and the second arc striking piece, striking effect is increased, arc extinguishing ability is more preferably.
