Description
Technical field
The utility model relates to breaker parts technical field, the peace of electromagnetic release mechanism on especially a kind of breaker
Assembling structure.
Background technique
Breaker be can turn on, carry and disjunction normal circuit under the conditions of electric current, also can be in the improper of defined
It is connected under circuit (such as short circuit), a kind of device for switching of carrying certain time and breaking current.Electromagnetic tripping system is open circuit
Extremely important component part in device, and mechanically form a whole with breaker；For overloading, short-circuit protection
Function.Its working principle is that: by galvanomagnetic-effect it is found that electricity understands magnetisation, but when line current is normal, the power of instantaneous reaction spring
Greater than the magnetic force that electric current generates, armature is to separate with iron core, and when occurring short circuit current in route, the magnetic force of iron core can increase
By force, so that the gravitational attraction armature movement lead agency of instantaneous reaction spring be overcome to act to cut off circuit；Existing electromagnetism is de-
Buckle mechanism generally includes iron core 31, armature 33, instantaneous spring 35, bimetal leaf, brass bracket 34 and rivet as shown in Figure 1
32；Brass bracket 34 is arranged in 31 mounting base two sides of iron core, and armature 33 is rotatably arranged on brass bracket 34, instantaneous 35 hook of spring
It is located between brass bracket 34 and armature 33, this electromagnetic release mechanism needs in technique will by riveting or welding manner
Brass bracket and iron core mounting base are combined into an entirety to place armature, and the various complexity of installation steps, greatly increase at
The waste of this and material；In addition, design of part complexity is more demanding to production technology and mold, while brass bracket cost is also very
Height, so that product cost increases, the positioning also bad control between part, so that installation is increasingly complex.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of mounting structure of electromagnetic release mechanism on breaker,
Its improvement is simple and reasonable, so that structure is more simple, it is convenient to install and use.
The utility model provides a kind of mounting structure of electromagnetic release mechanism on breaker, including pedestal and electromagnetic trip
Mechanism, the electromagnetic release mechanism include armature, iron core and instantaneous spring, and mounting groove, the iron core are provided on the pedestal
Setting corresponds to plunger position on mounting groove, the mounting groove two sidewalls and is provided with fixing groove, and the armature two sides, which are provided with, to be turned
Axis, the shaft are set in fixing groove, and the armature is rotatably arranged in mounting groove by shaft, and the instantaneous carbine is set
The limit rotated to armature is formed between armature and mounting groove.
The beneficial effect being arranged in this way is: using the above scheme, the brass supporting structure for including in original structure is eliminated,
Expensive metal parts has been saved, the cost of product is reduced, armature has directly been arranged on pedestal by shaft, while fixing groove
It is that same pedestal passes through Mold Making together, hardly increases cost, using Mold Making fixing groove not only without technical difficulty,
And fixing groove positioning is more accurate, simple, while also reducing the difficulty of assembly, improves the efficiency of production and processing, and same
Sample can play the role of electromagnetism and take off mouth mechanism.
It includes bayonet and rotation slot that the utility model, which is further arranged to the fixing groove, and the bayonet width is greater than shaft
Diameter setting, the shaft are rotatably arranged in rotation slot, the shaft and rotation slot clearance fit.
The beneficial effect being arranged in this way is: using the above scheme, this installation slot structure is simple, is conducive to realize, passes through mould
Tool can be very good to process, while bayonet and rotation slot is arranged, and bayonet has certain guiding role to the installation of shaft,
The installation of more convenient shaft is caught in simultaneously, improves production efficiency.
The utility model is further arranged to the bayonet width and is arranged greater than rotation slot notch, the bayonet and rotation slot
It is connected between notch by inclined-plane.
The beneficial effect being arranged in this way is: using the above scheme, inclined-plane is arranged, shaft is more easily pacified
Dress assembles more laborsaving.
The utility model is further arranged to the shaft and is arranged in square shaft.
The beneficial effect being arranged in this way is: using the above scheme, shaft is arranged to square shaft, is arranged in rotation slot in this way,
It contacts under normal condition with rotation groove bottom for line, when needing to rotate, since line contact can effectively realize rotation, but rotates
When being contacted to square shaft face and rotation groove bottom, due to being the conflict in face and face, to can not rotate, limitation armature can be played and turned
Dynamic angle improves the accuracy that product uses, and improves using effect, replaces the limit convex role on original armature.
Detailed description of the invention
