Description

High current miniature circuit breaker
Technical field
It the utility model is related to a kind of high current miniature circuit breaker.
Background technology
Miniature circuit breaker, especially high current miniature circuit breaker can produce electric arc in disjunction, and electric arc draws along run-on tab Separate in arc-extinguish chamber and extinguish, in high current disjunction, because electric current reduces rapidly, magnet coil can produce induced-current obstruction Electric current reduces, so that the electric arc between static contact and moving contact can not quickly extinguish, influences the normal disjunction of miniature circuit breaker, And miniature circuit breaker internal temperature rise is improved, it is to improve one of big obstruction for miniature circuit breaker rated current.
The content of the invention
The purpose of this utility model is solve above-mentioned technical problem, there is provided one kind prevents caused heat gas in arc-extinguish chamber The high current miniature circuit breaker altered on body and electric arc.
To achieve the above object, the utility model uses a kind of high current miniature circuit breaker, including housing and is arranged on shell Internal operating mechanism, electromagnetic system, arc-extinguish chamber, binding post, operating mechanism and electromagnetic system are arranged on the top of housing, go out Arc cover is arranged on below electromagnetic system, and binding post is arranged on housing both ends, and electromagnetic system includes magnet coil, static contact, electricity Magnetic coil both ends are connected with binding post and static contact upper end respectively, and static contact lower end forms aduncate bending section, bending The upper run-on tab extended to above arc-extinguish chamber is connected with portion, upper run-on tab extends in parallel along arc-extinguish chamber upper surface, it is described on draw Arc plate includes first half and latter half of, and first half is connected with static contact, latter half of to be connected with binding post, latter half of and first half Between form one of gap.
The end that the utility model is further arranged to the first half of the upper run-on tab forms a breach, upper run-on tab Latter half of front end form projection and be plugged in the breach.Cooperated by raised with the breach of indent, by this Mutually interspersed cooperation, make electric arc be more prone to across upper run-on tab first half and it is latter half of between gap.
The first half front end that the utility model is further arranged to the upper run-on tab is welded in the bending section of static contact Side.
The utility model, which is further arranged to the binding post, includes wire frame and terminal plate, and terminal plate includes outer company Portion, transition part, interior portion of company, outer portion of company and interior portion of company are horizontally disposed with, and transition part vertical connection connects between portion and interior portion of company outside, outside Portion of company is plugged in wire frame, and interior portion of company is connected with magnet coil one end, and the latter half of of upper run-on tab is connected on transition part.
The beneficial effects of the utility model are that upper run-on tab is extended on binding post from static contact lower end, and in upper striking Electric current during one section of crack cut-off normal power-up is set among plate, and in disjunction high current, electric current caused by electromagnetic induction can be straight Run-on tab was connected, because upper run-on tab is short more than magnet coil, passes through the far fast mistake of the reduction speed of the electric current of upper run-on tab By the reduction speed of magnet coil, therefore reach the quick purpose for reducing electric current, realize the quick disjunction of electric arc, greatly improve The rated current of miniature circuit breaker.
