Abstract
The invention relates to an integrated yoke element of a small type circuit breaker, which is characterized in that the yoke and an iron core are designed as an integrated element. The iron core is embedded in the coil of the small type circuit breaker; the shape of the iron core is designed as a U shape or an L shape or a closed square-shaped contour; the iron core is provided with a magnetic pole plane, the middle of which is provided with an opening hole which is used for guiding an armature; and a convex shoulder which is used for supporting and fixing a static contact stent is arranged on the yoke. As the yoke and the iron core are designed as the integrated element which is formed by ferromagnetic metal material with good magnetic conductivity by punching, the structure of the yoke element is simplified and the type of the part is decreased, which not only saves the processing cost of raw materials, but also brings convenience for the warehouse management and reduces the equipment investment; simultaneously, the turning pieces with high price is reduced, the production cycle is shortened, and the magnetic circuit of a magnetic release is improved, thereby leading the performance of the whole circuit breaker to be more stable and reliable.
Description
Technical field
The present invention relates to a kind of integrated magnet yoke element of miniature circuit breaker, specifically be used for the integrated magnet yoke element of the magnetictrip of miniature circuit breaker.
Background technology
Miniature circuit breaker has overload and short-circuit protection function usually.Wherein overload protection function is sensed heat by thermal element and is produced the crooked breaker mechanism turn-off current loop that promotes and realizes, thus the magnetictrip induction that short-circuit protection function is formed by elements such as comprising coil, armature, magnetic core, yoke and set up magnetic field and make armature motion and promote the realization of breaker mechanism turn-off current loop.In prior art, the magnetic conductive component of existing miniature circuit breaker (L7 Series Circuit Breakers) mainly comprises yoke, magnetic core, armature, yoke and magnetic core rivet together, a stationary contact bracket also rivets together with yoke and magnetic core simultaneously, and yoke rises magnetic core, armature and stationary contact bracket and supports and positioning action.Yoke also has at the magnetictrip induced current sets up the function that makes its magnetic circuit realization at utmost closed in the magnetic field process.The magnet yoke element of this kind structure is the square structure of sealing, raw material production cost height.In the magnetic circuit yoke and magnetic core by two independently element form and rivet together, comprising the higher turning part magnetic core of production cost, cost of material, processing cost, warehouse cost height, because the existence of riveting point has also influenced the performance of magnetic circuit, easily make the inconsistent of magnetic field in the loop, thereby influence the consistency of end properties.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, can reduce production costs and the warehousing management cost thereby provide a kind of; Can shorten the production cycle, the consistency of the magnetic property of magnetictrip is fully improved, and can makes the integrated magnet yoke element of the more stable magnetictrip of circuit breaker machine performance.
According to technical scheme provided by the invention, the integrated magnet yoke element of miniature circuit breaker comprises yoke, iron core, and feature is: described yoke and iron core are made as integrated element.
Described iron core is embedded in the coil of described miniature circuit breaker; Described core configuration is made as U-shaped or L shaped or closed square profile; Described iron core is provided with a magnetic pole plane; Be provided with the perforate that is used to guide armature in the middle of the magnetic pole plane on the described iron core; Described yoke is provided with one and is used to support and the fixing convex shoulder of stationary contact bracket.Described yoke and iron core are formed by the ferrimagnet punching out.
Compared with the prior art the present invention has the following advantages:
The incorporate element that the present invention because yoke and magnetic core be designed to is formed by the good ferromagnetic metal material punching out of magnetic conduction, the structure of magnet yoke element is oversimplified more, reduce the part kind, not only saved the processing cost of raw material,, and can reduce equipment investment also for warehousing management has brought convenience, reduced the higher turning part of price simultaneously, shortened the production cycle, also improved the magnetic circuit of magnetictrip, thereby made the circuit breaker machine performance more reliable and more stable.
