Abstract
The invention relates to an electromagnetic current releasing device (1), wherein a fixed magnetic core (6) which forms part of the magnetic system is built as a single piece with a terminal (8) used for connecting the magnetic spool (2) of the magnetic system, in the form of a stamped and bent piece. A cost effective current releasing device can thus be obtained.
Description
Technical field
The present invention relates to a kind of electro-magnetic circuit breaker that is used for electric protective circuit breaker, it has a magnetic coil, one movably armature and one by the fixing magnetic core in the electric current binding post holding position of magnetic coil.
Background technology
The electro-magnetic circuit breaker of type shown in Figure 2 is used for the overload current of conventional electric protective circuit breaker, and the especially identification of short circuit current produces abnormal operating state to avoid one pole or multipole electrical appliance.These protection switches can be power switchs, motor protecting switch and wire-protecting switch.The response limit internal cutting off overcurrent that they must determined according to effective regulations respectively.For this purpose, circuit breaker is connected as follows with the contact that protection switch will disconnect, and promptly it can disconnect the contact of protection switch as the reaction to overload current or short circuit current or keep where necessary opening circuit.According to Fig. 2, such circuit breaker 1 has 3, one of the coil pipes of conduit 4 by 2, one of magnetic coils, and movably 6, one springs 7 of magnetic core and an electric current binding post 8 of 5, one fixed-site of armature are formed.The coil pipe 3 that has conduit 4 is made by insulating material.Twine or be set with magnetic coil 2 around coil pipe 3.The armature 5 of mobile-bearing moves as the spring force that the reaction to overload current or short circuit current can overcome spring 7 in conduit 4.Whereby, realize that by corresponding mechanical couplings element the contact that is positioned at current path disconnects.As shown in Figure 2, magnetic core 6 is pressed in the conduit 4 of coil pipe 3 or in the binding post 8.Magnetic core 6 is adapters, and it preferably is bearing in conduit 4 inside, promptly is located at least in part in the inner chamber of magnetic coil 2.
Swiss Patent document CH 616 271 A5 disclose a kind of electromagnetic release device of protection switch, and it has a bobbin that has a coil, are provided with a moving core as the operating mechanism of an engagement lever in the inside of this bobbin.This moving core is supported on the magnetic core that projects in the bobbin by an armature spring.The part seat of bobbin is placed on this magnetic core.In addition, be provided with the magnetic conductance yoke that a ring encloses this coil, this magnetic conductance yoke is made of the magnetic conductance plate of a U type and another magnetic conductance plate of its open side of sealing, and wherein a magnetic conductance plate is equipped with magnetic core, then has a perforate that is used for moving core on another piece magnetic conductance plate.
Summary of the invention
The technical problem to be solved in the present invention is that part reduces the size of the above-mentioned type electro-magnetic circuit breaker and therefore makes it economically.
Above-mentioned technical problem solves by a kind of electro-magnetic circuit breaker that is used for electric protective circuit breaker; this electro-magnetic circuit breaker have a magnetic coil, one movably armature and one by the fixing magnetic core in the electric current binding post holding position of magnetic coil; according to the present invention, this magnetic core and electric current binding post are made one.
A kind of economic especially form of implementation is that magnetic core and electric current binding post are made the sheet metal bending part of one.
Description of drawings
Below with reference to accompanying drawings embodiments of the present invention are described further, in the accompanying drawing:
Fig. 1 illustrates circuit breaker of the present invention;
Fig. 2 illustrates disclosed breaker structure.
Embodiment
Movably form by 3, one of coil pipes that has conduit 4 that insulating material is made by 6, one springs 7 of magnetic core and the circuit connection post 8 as main element of 5, one fixed-site of armature by 2, one of magnetic coils for electro-magnetic circuit breaker 1 among Fig. 1.Magnetic coil 2 twines or is enclosed within on the coil pipe and as the part of the current path of protected electrical appliance.Armature 5 is bearing in movably in the conduit 4 and to short circuit current and reacts.The corresponding mechanical couplings element that moves through of armature 5 disconnects the contact that is positioned at current path.At this, armature 5 overcomes the spring force effect that is located at the spring 7 in the conduit 4 equally and moves.For making circuit breaker 1 obtain steep force curve, in the conduit 4 of coil pipe 3, be provided with the magnetic core 6 of a fixed-site, the electric current binding post 8 of it and magnetic coil 2 is made integral piece.This integral piece is preferably made sheet metal bending part.
Claims (2)
1. electro-magnetic circuit breaker that is used for electric protective circuit breaker; it has a magnetic coil (2); one movably armature (5) and one is characterized in that by the fixing magnetic core (6) in electric current binding post (8) holding position of magnetic coil (2) magnetic core (6) and electric current binding post (8) are made one.
