Description
Technical field
It the utility model is related to a kind of breaker, more particularly to a kind of high current miniature circuit breaker.
Background technology
At present, miniature circuit breaker is mainly used in industry, business, high-rise and residential houses, but a kind of existing circuit breaker electric
The coil of magnetic system is connected on connecting plate, and short circuit current is directly by coil, because failure cause overloads coil, to coil
The requirement of overload capacity is very high, and the arc striking piece of breaker is placed in beside arc-chutes cavity, during contact of breaker opening and closing, electricity
Arc will not lead to arc-chutes quickly, can cause the easy ablation of contact of breaker, influence the pitch capability of breaker, cause product
It can decline.
The content of the invention
In view of this, the purpose of this utility model is that coil and the more preferable high current of striking performance can be protected by providing one kind
Miniature circuit breaker.
In order to realize the above object the utility model uses such a high current miniature circuit breaker, including pedestal and set
Electromagnetic system, binding post in pedestal, the electromagnetic system include coil, coil rack, connecting plate, yoke, the connection
Terminal includes wire frame, and the coil rack, connecting plate, yoke are fixed on pedestal, and connecting plate one end is connected in wire frame,
The other end is bent to form downwards static contact, and static contact lower end is bent to form striking portion, and the both ends that coil is drawn are welded on connecting plate
On, yoke is divided into vertical component and horizontal component, and yoke vertical component is positioned close to coil rack one end of static contact, close
Yoke horizontal component one end of static contact diagonally descend direction draw one section of arc end, arc end face striking portion, arc end and
There is gap in striking portion.
Said structure causes partial short circuit electric current to flow through coil, protects coil, and arc end in yoke is because electromagnetism
Attraction, by contact separate caused by electric arc quickly guide to arc-chutes, accelerate the quenching time, protect contact.
This practicality is further arranged to the top that coil is located at connecting plate, to concave into one section of concave surface among connecting plate,
Both sides form convex surface, and lead-out wire of the coil close to wire frame side is welded in one end of terminal plate concave bottom, and coil is close to quiet
The lead-out wire of contact side is welded on the convex surface of terminal plate.
Said structure provides enough spaces by coil and coil rack installation, easy for installation.
This practicality, which is further arranged to yoke vertical component, arc-shaped slot and square neck, and coil rack passes through arc card
Groove, connecting plate pass through square neck.
Said structure is the motion for limiting yoke, makes the position of yoke more firm.
This practicality is further arranged to connecting plate one end and is connected to by the bending of right angle twice in wire frame, the wire frame
The terminal plate of top has a circular port, there is screw thread above wire frame, and screw can pass through the screw thread on circular port and wire frame
It is fitted close to fix.
Connecting plate is fixed on connection inframe, fixing internal and outside connection by said structure by screw.
