Definitions
- the invention relates to a trigger armature of an electromagnetic trigger for a switching device, which has a base body made of a ferromagnetic material.
- An electromagnetic release for a switching device uses, among other things, a release coil, a release armature with a plunger, a magnetic core and a magnetic yoke.
- the tripping armature is movable and separated from the magnetic core by an air gap. If a sufficiently large current flows through the tripping coil, the tripping armature is set in motion to bridge the air gap in the direction of the magnetic core. The movement results from the magnetic field building up.
- Such an electromagnetic release is known in connection with a circuit breaker from EP 0 518 791 B1.
- the construction of this electromagnetic release and that of the integrated release anchor is complex, the combination of release anchor and associated plunger also being linked to extensive production steps. Since a release anchor is usually designed as a rotationally symmetrical component, a manufacturing method such as a turning process is selected for this.
- a release anchor of the type mentioned at the outset in which, according to the invention, the base body is designed as an upset, pressed part or as a stamped, bent part.
- the design of the release anchor in this way makes the design and manufacture considerably simpler or less expensive than a conventional release anchor. Accordingly, comparatively low manufacturing costs are incurred as a turned part compared to the above-mentioned release anchor.
- the invention can save considerable manufacturing costs for the turned part, for assembly and for surface treatment.
- the cost of surface treatment can be eliminated by using pre-treated or, if necessary, pre-galvanized strips.
- the base body is preferably provided with a plunger.
- the plunger serves as an extension of the release armature and acts precisely on the switching mechanism to be actuated.
- the plunger is designed as a separate component and made of insulating material.
- the advantage here is that different materials with different material properties can be used, whereby a targeted change in the functional scope of the electromagnetic release can be effected.
- the base body with the plunger is designed as a one-piece structural unit.
- the resulting assembly advantageously contributes to a reduction in the assembly time of the electromagnetic release.
- At least the base body is advantageously formed from a flat material.
- the tripping armature formed therefrom can also be used in a flat electromagnetic release and therefore also in a flat switching device.
- At least the base body can have a round, an approximately oval or an angular cross section. This gives greater design freedom, which means that additional functional contours or designs can be easily implemented.
- the base body expediently has a hole which is made transversely to and in the region of the longitudinal axis of the plunger.
- the opening serves to interrupt the magnetic field, thereby preventing the magnetic field lines which are given thereby from penetrating as far as the plunger tip.
- FIG. 1 and 2 show a first release anchor with and without a separate plunger in different views
- FIG. 3 shows a second release anchor with a separate one
- the first release armature la has a base body 2a, which is formed from a ferromagnetic material and as an upset, pressed part or as a stamped, bent part.
- the production of the first release armature la takes place by means of a die and stamp, which gives an enormous cost advantage compared to a turned part. It is also possible to use a metal injection molding or a sintered part.
- the sintered part is formed on the basis of a ferromagnetic powder.
- the first release armature la has at the end a plate 3 and an inner recess 4a, in which a plunger 5a is arranged.
- the plunger 5a is guided and supported in an opening 6.
- the opening 6 is made in a magnetic core 7 and in an extension 8 of a magnetic yoke 9.
- the first release armature la with its plunger 5a as well as the magnetic core 7 are encompassed by a release coil 10 and extend along the longitudinal axis LA.
- the first triggering armature la forms, together with the other components listed above, an electromagnetic trigger 11 for a switching device 12.
- the plate 3 provided at the end on the first release armature la can be flattened at least on a portion of its radial course for guiding purposes.
- FIG. 3 shows a second release armature 1b with a base body 2b.
- the second release armature 1b here comprises a plunger 5b.
- the base body 2b is formed from a flat material into a cylinder with a butt edge 13, so that a recess 4b is formed.
- the flat material can optionally also be wound like a screw.
- the cylinder has a first and a second recess 14 and 15, respectively, in shape, position and size match and in particular are symmetrical. Alternatively, additional component ratios can be provided by means of individual adaptation.
- the plunger 5b has, in addition to an end piece 16, a retaining lug 17 which is received by the recesses 14 and 15 which stand together. As a result, the plunger 5b is non-positively and positively connected to the second release armature lb. Any tolerance that may arise between the retaining lug 17 and the recesses 14 and 15 is compensated for by spacer ribs formed on the retaining lug.
- the holding lug 17 lies in particular on the side of the recesses 14, 15 facing the end piece 16 for the purpose of positioning.
- the end piece 16 is analogous to the plate 3 according to FIGS. 2 and 3.
- FIGS. 1 to 3 Depending on the affiliation, the following section relates equally to FIGS. 1 to 3.
- the first and second release anchors la and lb as well as the plunger 5a and 5b can be made of a metal. To avoid arcing, a shorter release lever, a shielding device or an insulated plunger tip can be used. As an alternative to this, the separate plunger 5a or 5b can optionally be formed from a non-ferromagnetic material or from an insulating material. This advantageously prevents an electrically conductive connection to adjacent components, avoiding the risk of arcing.
- trip anchors 1b to 1f according to FIGS. 3 to 7 can equally be used in an electromagnetic release analogous to the variant of the electromagnetic release 11 according to FIG.
- the base body 2c is designed with a plunger 5c as a one-piece structural unit.
- the third trigger Seanker 1c differs from the second release anchor 1b according to FIG. 3 in that a U-shaped profile 18a is provided on the side opposite the abutting edge 13.
- the U-shaped profile 18a is arranged parallel to the longitudinal axis LA.
- a remaining web 19a is in turn formed in a U-shaped angle to the plunger 5c, which is guided through a recess 4c and extends along the longitudinal axis LA.
- the base body 2c has an arcuate cross section.
- FIG. 5 shows a fourth release armature 1d with a base body 2d.
- a U-shaped profile 18b or a notch 20 is formed on the circumference of the fourth release anchor 1d in an axial and a radial section.
- a web 19b remaining from the U-shaped profile 18b is deformed in its original orientation in such a way that it engages in the notch 20 and forms a plunger 5d.
- the shape of the fourth release armature ld is given in that the flat, ferromagnetic material is first provided with an incision in the longitudinal direction LA. This incision creates a section that forms the plunger 5d after it has been deformed. The flat, ferromagnetic material is then formed into a cylindrical tube, which gives the release armature ld.
- the base body 2e on which the fifth release anchor le is based is likewise formed from a flat material, but has two legs 21 and 22 which lie one on top of the other and which are connected to one another via a first and a second radial piece 23 and 24 are connected.
- a U-shaped profile 18c inserted between the two legs 21 and 22 results in a remaining web 19c which extends over the dimensions of the fifth release anchor le along the longitudinal axis LA.
- the flat, ferromagnetic material is thereby recessed in the center and folded transversely to the longitudinal axis LA, so that a plunger 5e is formed.
- FIG. 7 shows a sixth release anchor If with a base body 2f.
- the flat material is shaped in such a way that there is an approximately oval cross section at the sixth release anchor lf.
- the flat material is provided with a plunger 5f.
- a hole 25 is made on one side of the base body 2f and is arranged transversely to and in the region of the longitudinal axis LA of the plunger 5f.
- the hole 25 serves to interrupt a magnetic field, thereby preventing magnetic field lines from reaching the tip of the plunger. This version is particularly advantageous for a narrow trigger and switch variant.
- the respective base bodies 2a to 2f can in particular be formed from a flat material of 0.05 to 5 mm.
- the material thickness of the flat material is preferably in a ratio of 1 to 5 to the diameter or to the total height.
- the first to the sixth base body 2a to 2f can have at least a round, an approximately oval or an angular cross section. Other dedicated shapes, profiles and cross-sections can also be implemented.
- the first to the sixth tripping anchors la to lf can also be designed in any way. This can include plate-shaped, U-shaped or T-shaped designs.
