Definitions
- the invention first relates to an electrical switching device, in particular a relay comprising a housing, one arranged in the housing and carrying a coil Magnetic angle, a core arranged on the magnetic angle the coil, at least two arranged in the housing Terminals, one of which is connected to the magnetic bracket and resilient at the magnetic angle arranged anchor, by its actuation a contact producible between the at least two terminals is.
- a relay comprising a housing, one arranged in the housing and carrying a coil Magnetic angle, a core arranged on the magnetic angle the coil, at least two arranged in the housing Terminals, one of which is connected to the magnetic bracket and resilient at the magnetic angle arranged anchor, by its actuation a contact producible between the at least two terminals is.
- Such a switching device goes for example from DE 44 11 879 A1.
- the Magnetic angle and the core of the coil as one piece Configured elbow, the magnet angle at right angles is angled. Parallel to an upper one Magnetic angle part is also angled the core arranged so that it is parallel to the upper magnetic angle part runs.
- a Distance provided that is substantially half Corresponds to coil diameter.
- At the magnet angle is attached a terminal.
- the invention is therefore based on the object of an electrical Switching device, in particular a relay of Generic type to improve such that this on simple and with the least possible use of materials, i.e. with as little material loss as possible can be manufactured.
- the invention is in an electrical switching device, in particular a relay of the type described above solved according to the invention in that the magnetic angle, the Core and the one connected to the magnetic angle, at least a connecting terminal is a curved, one-piece stamped part are in which the core in the unbent state as one in the tongue, lying separately, bendable tongue is trained.
- the formation of the magnetic angle, the core and the with the magnetic angle connected, at least one terminal as a curved, one-piece stamped part great advantage that both the magnetic angle and the core the coil as well as the connection terminal with only one single punching process can be produced. On this way there is no additional fastening of the Terminal / s and the magnetic core on the magnet angle.
- the core in the unbent state as one in separately bendable tongue located at the magnetic angle is formed in a particularly advantageous manner Manufacturing the core of the coil requires little material necessary, i.e. it arises during manufacture only a small loss of material in the core.
- the stamped part can be used to form the Magnet angle, the core and the terminal one have any shape and form.
- the tongue in that Magnetic angle can also vary Way be trained.
- the stamped part is essentially one has a rectangular shape, on one side of the Terminal is formed and that it is essentially in the middle a very narrow U-shaped recess that for example, only by pulling out or cutting out is manufactured to form the core bendable tongue and the bendable to the elbow, has the rest of the stamped part surrounding the tongue.
- a very advantageous embodiment provides that the Tongue directly from the magnetic angle by pulling out or Cut out and by immediately following Bending the core will be formed. In this way the U-shaped recess can be omitted, which results in results in a further reduction in material waste.
- the tongue and the the tongues surrounding the tongue are bent in such a way that between the upper magnetic angle part and the core Distance arises, which is essentially half the diameter corresponds to the coil. In this way, the Coil on the magnetic bracket in a simple, exact manner be positioned and attached.
- FIG. 1 An embodiment of an electrical switching device, in the form of a microrelay, shown in FIG. 1 a housing designated as a whole by 10.
- the housing is a magnetic bracket 30 that carries a coil 20 arranged.
- At the magnetic angle 30 is a core 32 Coil 20 arranged.
- the distance between the core 32 and an upper one Magnetic angle part 31, which is also used as a magnetic closure element serves, is chosen so that he the half the diameter of the coil 20 corresponds substantially.
- On the upper magnetic angle part 31 is a Rivet connection 40 arranged an anchor 42.
- the anchor is via a leaf spring 43 resiliently supported by the magnetically energized coil 20 attracted, causing a at the bottom of the leaf spring 43 attached contact element 44 on a contact element 52, which is connected to a further terminal 50 is coming to the plant.
- Terminal 35 At the magnetic angle 30 is in the lower area Terminal 35 provided.
- the terminal 35, the Terminal 50 and the terminal 60 are in lower part of the housing, for example, in a sealing compound 70 embedded.
- the magnetic angle 30 also forms whose upper magnetic angle part 31, the core 32 and the Terminal 35 a single part.
- Fig. 2 is first from a sheet a part punched out that is a substantially rectangular Shape 39 has. On one side of this rectangular part 39 is a known per se Terminal 35 formed in one piece.
- Sheet 39 Essentially centered in the stamped, rectangular shape Sheet 39 is a very narrow U-shaped recess 38 to form a likewise rectangular tongue 32a.
- This tongue 32a is shaped by a remainder of the rectangular Surround sheet 39, which is essentially parallel to two of the tongue 32a arranged webs 30a and one with these two webs 30a connected continuous rectangular Part 31a includes.
- the upper magnetic angle part 31 and the core 32 are now both Tongue 32a to the core 32 as well as the tongue 32a surrounding rectangular part arranged on webs 30a 31a bent to the upper magnetic angle part 31.
- the bending of the tongue 32a and that of the webs 30a arranged rectangular part 31a takes place in the part shown in Fig. 3 in the sheet plane.
- the bending of the webs 30a takes place at one point such that the rivet pins 40 are arranged at a position that is precise Attachment of the armature 42 by means of the leaf spring 43 enable a riveted joint.
- Another embodiment of the manufacturing process provides that the tongue 32a directly from the Magnetic angle 39 by pulling out or cutting and by immediately bending the core 32 be formed. This way the very narrow one U-shaped recess 38 can be reduced to a minimum, resulting in a further reduction in material waste results.
- the formation of the magnetic angle 30 and the core 32 by a stamped part with that arranged in the stamped part Tongue 32a not only enables quick and unproblematic, but also a particularly material-saving one Production of the magnetic angle 30, the core 32 and the terminal 35. Essentially arises only through the U-shaped recess and through the complement of the terminal 35 material waste, which is very small.
