The invention relates to electromagnetic relays which are arranged in layers one above the other Own iron circles, which are built up from river bow, core bow and anchor, which with its free End protrudes into a working air gap formed by the two brackets, with parts of the iron circles at the same time serve as an electrical conductor that a contact attached to the armature with cooperates with another contact, preferably connected to the core clip.

In the previously known relay of this type, the parts of the iron circles in the interior of the Coil body for the magnetization winding provided guides attached by inserting. These guides are formed in one piece with the coil body.

The purpose of the invention is to train the support of the iron circles so that once the assembly of such relay simplified and due to the design of the carrier the possibility of an advantageous, Protected accommodation of the contacts is created within the carrier.

This purpose is achieved in that, according to the invention, the carrier corresponds to the arrangement the iron circles are divided into several layers, the flat individual parts of the iron circles are inserted between the layers of the carrier and the entire arrangement by connecting the individual Layers of the carrier is combined into one structural unit.

It is known per se to build an electromagnetic relay so that between several one above the other arranged iron circles insulating plates are inserted and the entire arrangement through Screws is held together, so that an order is created, as is the case with the known layer structure of contact spring sets is the case.

It is also known to have a number of juxtaposed protective tube contacts in the Define dividing lines between two half-shells, whereby the half-shells are connected to one another. In contrast to this, the relays on which the invention is based are one above the other, that is, not next to one another arranged iron circles and also have magnets made up of rigid brackets are, while the known arrangement involves resilient contact blades.

The simplification achieved by the invention in the assembly of the relay can be seen in the fact that the Recordings for the individual iron circle parts are initially open in their entire extent and the individual parts of the iron circuit in a simple manner. Electromagnetic relay

can be inserted. The advantages of such a design of the carrier in terms of accommodation of the relay contacts can be seen in the fact that this makes it possible to change the positions of the carrier to be designed so that they enclose the iron circles in such a way that the contact points are self-contained Spaces. The layers of the carrier can also have such a shape give that the iron circles lying in the different layers of the relay are not in one another Connecting rooms can be accommodated.

In a manufacturing-simplifying manner, according to a further embodiment of the invention, all Layers of the carrier designed in the same shape. Only to cover the upper iron circle layer If necessary, a cover of a different, simpler shape can be used. In advantageous Thus, the carrier layers are made completely smooth on one side and on the opposite side Provide the side with trough-shaped receptacles, which take up the iron circle parts.

Another simplification in production, which also has a beneficial effect on the assembly of the relay, is achieved in that the edges surrounding the trough-shaped recess completely are evenly trained. In the above-mentioned known arrangement of protective tube contacts between two half-shells on the edges of a shell incisions are provided in which the contacts be inserted. The disadvantage on which this arrangement is based is due to the tolerances The inaccurate adaptation of the contact blades to the incisions caused by the spring material is caused by the above-mentioned design of the layers of the carrier avoided. This advantage is particularly

This is also the case with this arrangement bracket, at its other end with the anchor around a relay strip that differs from the arrangement is welded. The axis of rotation of the armature is distinguished by 65 according to FIG. 2 in that the next one Expression 23 is formed on which the armature with superimposed relays in each iron circuit layer rests on its rear part. In the vicinity of its two opposite ends, one in the public domain, there is an overlapping cylindrical core bow and with corresponding

have river brackets equipped for the anchors. The carrier layers are denoted by 37 and 38. Of the In this case, too, the core clip 39 is for all iron circuit layers of the relays lying next to one another formed together as a one-piece component and has essentially the same shape as the in Fig. 2 with 18 designated core bracket. It differs from this only in the way it is fitted with differently shaped contact springs 40. These are slotted on both sides and protrude with consideration on the anchors arranged on both sides of the core yoke to both sides over the core yoke. As in the example described above, they are provided with contact points. The associated River brackets 20 do not differ from the river brackets used in the arrangement according to FIG. Each iron circle layer in the arrangement shown in FIG. 4 has twelve river brackets. There are but in the representation of the layer shown, for the sake of clarity, only two river brackets shown. There is a difference in the design of the iron circle parts compared to the arrangement according to FIG. 2, furthermore in the formation of the flux return. It is a bar-shaped with the core bracket 39 Sheet metal 41 welded. The river bracket ends over the aforementioned sheet metal with the core bracket connecting sheets are designed as separate web-shaped components 42 and 43 for both sides. The river return can, as will be shown on the basis of the next figure, also be designed differently.

According to the arrangement of the iron circle parts are the carrier layers, which are again used for each layer. common components are shaped, double-comb-shaped and have corresponding trough-shaped depressions 44, which in this case have a double-T-shape. The equipment and compilation of the individual carrier layers takes place in the same way as for the arrangement according to Fig. 2 and need not be described in more detail. In contrast to the In the embodiment according to FIG. 4, there are two contacts in each case enclosed spaces.

Of course, in the arrangement according to FIG. 4, any number of iron circles can be arranged in layers Arrangement can be put together one above the other.

5 and 6, a relay strip with four superimposed iron circles is shown, its Individual parts formed and assembled essentially in accordance with the instructions in FIG are.

The plan view shown in FIG. 5 primarily illustrates the coil assembly of the relay strip. The individual carrier layers are connected to one another by fusing and form a closed unit with the protruding ends of the flow bracket 20, the core bracket 39 and the metal sheets 41. For each row of the armatures arranged one above the other, excitation coils 45 are provided which, as already mentioned above, are slipped onto the parts of the carrier layers surrounding the armatures as coreless coils. Furthermore, this relay strip has holding coils 46, two holding coils being provided for six adjacent relays.

As mentioned, the coils are simply pushed onto the carrier. Serve to hold them Isolierstoffplatten 47, which, provided with corresponding slots, on the protruding from the support body Ends of the river bow 20 and the metal sheets 41 are pushed on. These panels are through magnetically conductive sheets 48 are held and thus in turn place the coils of the relay strip fixed. The plates 48 serve at the same time to return the flux, i. that is, they take over in addition to their fastening functions the task of in Fig. 4 with 42

ίο and 43 designated bar-shaped, magnetically conductive Sheets. The sheets 48 are bent in a U-shape in the longitudinal direction of the relay strip continuous ribs 49 provided which have correspondingly arranged slots through which the free ends of the core clip or the metal sheets 41 pass through. These slots are like that dimensioned so that the sheets clamp onto the components. It must of course take care of it be worn so that the flux bow are not electrically connected by these sheets, which is easy can be achieved by inserting a thin insulating film on the inside of the sheets. the mentioned plates 47 serve at the same time as carriers of rectifiers 50. As can be seen from FIG. a separate rectifier is assigned to each relay. The coil wiring is through a contact clip 51 simplified, which is clamped in a recess 52 of an outer carrier layer. The sheets 48 are for each side of the strip as a single piece, referring to all on that one Side of the carrier piercing components formed clamping component. It's in deviation Of course, it is possible to use a separate sheet for each of the adjacent rows of components to be provided.
