Description
Technical field
The utility model relates to a kind of tripping mechanisms of miniature circuit breaker.
Background technique
The tripping mechanism of miniature circuit breaker is the mechanism that breaker disjunction is controlled by electric signal, and existing breaker is general
Short-circuit protection is carried out using magnetictrip, having a single function for this magnetictrip can only accordingly short circuit overcurrent be protected, cannot
Meet the intelligent electric control protection to become increasingly abundant now to require.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provide it is a kind of it is full-featured, structure is simple
The tripping mechanism of miniature circuit breaker.
To achieve the above object, the utility model uses a kind of tripping mechanism of miniature circuit breaker, including contact plate, tripping
Device, armature, suction disc, armature are arranged in parallel on contact plate lateral surface, and suction disc is arranged on the inside of contact plate and one end is hinged on rank
On iron, the side of suction disc forms push plate towards armature direction, and spring is provided between suction disc and contact plate, and buckle releaser setting is being inhaled
The mandril of plate side, buckle releaser is withstood on suction disc.
The utility model has the beneficial effects that the tripping mechanism of miniature circuit breaker simultaneously use suction disc realize short-circuit protection and
Buckle releaser withstands suction disc and realizes electronic control, and suction disc provides the basic short-circuit protection of breaker, and buckle releaser passes through electronic control,
Realize intelligent control.
The utility model is specifically configured to the mandril of the buckle releaser and is withstood on suction disc with the direction perpendicular to armature.
The utility model is specifically configured to two side of armature and extends to form hinged seat, shape in hinged seat to contact plate inside
At hinge hole, described suction disc one end extends to form articulated shaft to two sides, and articulated shaft is set in hinge hole hingedly, one of hinge
Spring groove is formed on suction disc inside spindle, the spring is torsional spring, and torsional spring center is on the articulated shaft with spring groove, torsional spring
Both ends withstand on suction disc and contact plate respectively.
The utility model is specifically configured to that the contact plate is longitudinally disposed, and the lower end of contact plate extends and is bent upwards forward
Form static contact.
The upper end that the utility model is specifically configured to the contact plate forms horizontal upper contact plate, upper contact plate inwardly
Buckle releaser is enclosed in interior, the horizontal formation terminal board in the lower end of bending section by end downward bending.Contact plate is arranged around buckle releaser,
Space utilization is abundant.
The utility model is specifically configured to the push plate front end and is curved to the inside to form blade face.

At blade face 44, buckle releaser 2 is arranged in 4 side of suction disc, and the mandril 41 of buckle releaser 4 withstands on suction disc 4 with the direction perpendicular to armature 3
On, contact plate 1 is longitudinally disposed, and the lower end of contact plate 1 extends forward and is bent upwards to form static contact 6, the upper end of contact plate 1 to
Inside forms horizontal upper contact plate 11, and upper 11 end downward bending of contact plate is formed in buckle releaser is enclosed in by bending section 12,
The lower end of bending section 12 forms horizontal terminal board 14 by a step-like linkage section 13, and terminal board 14 is inserted into terminals
In son 7.
Above-described embodiment is the better embodiment of the utility model, other conspicuous improvements are in the utility model
Protection scope in.
