Definitions

• the invention relates to a twin relay according to the preamble of claim 1.
• twin relays in particular in telecommunications technology, which consist of two relays which are spatially separated from one another and which, for example, have a common yoke.
• twin relay support relay
• two independent relays are mounted on a common mounting base and the common element connecting the two relays is a mechanical locking of the two anchors.
• the invention is characterized by the technical teaching of claim 1.
• twin relay has at least two drives which are separate from one another, which drives each act on associated contact springs, and that both drives operate on a single common or at least partially common contact set.
• the main advantage is achieved that two relays are now arranged in one and the same relay housing, each of which is assigned its own independent drive, but the contact sets are combined with one another.
• Relays with positively driven contacts are used in a large number of applications which, due to the use of positively driven contacts, generally have similarities in terms of circuitry.
• the relays required to enable / disable the monitored circuits are always required twice. In principle, this is independent of the way in which the control of these two relays is carried out. Of course, this can also be done by means of relays, but also by electronics or by a combination of electronics and relays.
• such a unit can represent all elements for so-called extension modules.
• the contacts of the two relays can be combined.
• the individual contact no longer consists of an active and a passive spring, but of two active contact springs, each of which is moved by a drive.
• the overall height is formed by 2 levels.
• the drive systems are designed as polarized sliding anchors.
• Such sliding anchors are known.
• the contact set is located on the 2nd level.
• the properties such as positive guidance, fault tolerance, chambering, internal actuation, "bars" - spring combination etc. are available.
• the distribution of the connections on the underside of the relay is optimal for the user if the connections are distributed in the area of the outer edges. In this case, the remaining area covered by the relay is available for other components. If the connections are arranged centrally under the relay, the area for the conductor tracks to these connections is required.
• twins' active feathers are made in one piece. It is also conceivable that the passive contact parts are in one piece. This means that only the passive contact springs are routed to the outside; the series connection of the two contacts takes place internally. This applies first of all to the make and break contacts, which will later be available for external use.
• the load-bearing plastic element of this relay could be constructed in cross-section in such a way that the drives are fitted on one side and the contacts on the other flat side.
• the cover on the connection side and on the contact side would each be made by an element, which could be a cover or an enclosing hood.
• the cover / hood can also have partial walls which serve for the chambering or a laminated solid insulation.
• connection side can be so pronounced that it also represents the outer surface of a 22.5 mm wide housing.
• peripheral edge can be provided with a corresponding peripheral recess.
• the position of the actuator of the contact set can be used to set an optical feature on the narrow side for recognizing the actual position of the contact set (if the cover is sufficiently translucent)
• the subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.

• Figure 2 Schematic of the formation of a twin relay with the passive spring as an external connection
• Figure 3 Schematic of the front view of a relay
• Figure 2 Figure 4: An embodiment of a twin relay modified compared to Figure 2, wherein each individual contact consists of two active contact springs;
• Figure 5 Another schematic embodiment, which in
• the passive contact spring 2 has a front contact piece 5 and bears against a stop 4 fixed to the housing.
• the active contact spring 6 is actuated by an actuator 8.
• the term “internal actuation” is understood to mean that the actuator 8 with its drivers 11, which receive and guide the active contact spring 6 between them, is actuated in the space between the contact piece 12 and the clamping point in the spring bracket 1.
• the actuation takes place in such a way that the actuator 8 moves the active contact spring 6 in the direction of arrow 9 in the direction of closing on the passive contact spring 2, while the contact is opened in the opposite direction - arrow direction 10.
• the invention is not limited to the fact that the active contact spring 6 is taken between two drivers 11 (in FIG. 1, the one driver is designated 11a); it is also sufficient to spatially separate the drivers 11, 11a or to make them movable independently of one another.
• FIG. 2 shows such a twin relay 16, which consists of two partial relays 13, 14.
• the two partial relays 13, 14 are electrically separated from one another by a central, insulating partition 15.
• each partial relay 13, 14 is assigned, for example in the exemplary embodiment shown in FIG. 2, a common active contact spring 6.
• FIG. 2 shows that each partial relay 13, 14 has a total of four contacts, the respective contact being able to be designed either as a break contact, as a make contact or as a changeover contact.
• each contact is arranged in its own chamber 20, 21, 22, 23, wherein it can be seen that the parts arranged in the right part relay 14 are provided with a prime, compared to the same parts on the left side that belong to the partial relay 13.
• the invention is not limited to the fact that such contacts are arranged in electrically insulated chambers 20-23.
• the chambers 20-23 are namely separated from one another by corresponding horizontally running partition walls 17.
• the invention is not restricted to this.
• Such horizontally extending partitions 17 can also be omitted.
• the actuator 8 essentially consists of two parts, but this is also not necessary for a solution. It is sufficient here to provide only one actuator 19, which engages on one side of the active contact spring 6, 6 '.
• the opposite driver is referred to in the following as a positive guide 18 and has only the purpose of preventing the opener and closer from being closed at the same time. It is now important that the entire drive for the partial relay 13, which is referred to below as the partial drive 24, is mechanically separated and completely autonomous from the partial drive 25 for the right partial relay 14.
• FIG. 3 shows schematically that this drive system consisting of the partial drives 24, 25 is on one level below the partial relays 13, 14. That So the contact level is arranged above the level for the partial drives 24, 25.
• the levels are interchanged.
• the level for the drives 24, 25 is then arranged above the level for the contact sets of the partial relays 13, 14.
• Such a drive system could consist of two separate hinged anchor systems and a sliding anchor system. It is characteristic of both drives that both have a separate relay coil, which relay coil acts on an associated armature via a respective separate yoke and moves it.
• Each armature then acts in the arrow directions 26, 27 shown on the associated sub-drive system 24, 25 of the respective sub-relay 13, 14.
• a practical application can now be explained using the exemplary embodiment in FIG.
• the respective lower chamber 20, 20 'of the respective partial relay 13, 14 are each designed as openers. It is characteristic of these two break contacts that the active contact spring 6 is connected through and consequently electrically connects both break contacts to one another, so that these two contacts are electrically connected in series.
• the relay always consists of a series connection of contacts, but this series connection in each case shares an active contact spring. Due to the electrical interconnection of the active contact spring, it is no longer necessary to lead this active contact spring to the outside via separate connections and to connect it to one another outside of the spring bracket via assigned connections. The connections are therefore already made internally in the relay without the need for contacting without connecting lines and without corresponding conductor tracks.
• FIG. 4 shows as a further exemplary embodiment that each individual contact consists of two active contact springs, each of which is separate from the two drives (Partial drives 24, 25) are moved.
• the direction of movement of the two partial drives 24, 25 runs in opposite directions, because the actuation of the respectively active contact springs 6, 6 'takes place in opposite directions. This takes place in that on one contact spring 6 the actuator 19 rests on one side, while on the other contact spring 6- the actuator 19 rests on the other side.
• the two active contact springs 6, 6 ' which can be actuated separately from one another form a single contact 28 which is designed as an opener, but nevertheless there is a series connection in the sense of the previous FIG. 2 of two contacts.
• the respective active contact spring 6, 6 ' has the assigned external connection 3, 3', which is led out of the relay.
• Figure 5 shows the same conditions as in Figure 2, it can only be seen that the internal connections 3, 3 'of the respective passive contact springs are placed differently, i.e. they are brought out at another point in the spring frame.
• FIG. 6 is a variant of FIG. 4, the same explanations as those given with reference to FIG. 4 apply. The only difference is that the respective connection 3, 3 'of the respective active contact spring 6, 6' is now not led out to the outside of the relay, but is designed on the inside.
• FIG. 7 shows that the respective partial drive system 24; 25 of the partial relays 13, 14 also does not have to be arranged in alignment one above the other, but that the partial drive system is quite offset from one another. It is again important in this embodiment that the drive system 24 is actuated in the direction of the arrow 26, while the drive system 25 of the partial relay 23 is actuated in the arrow directions 27 separately from the other partial drive system.
• FIG. 6 shows that the upper part of the respective partial relay 13, 14 consists of an arrangement as has already been described with reference to FIG. 6, while the lower part, consisting of the chambers 30, 31 and 30 ', 31 'shows that both the active contact spring and the passive contact spring are guided outwards.
• the two partial relays, 14, 15 consist of different relay systems arranged one above the other, the two relay systems each having a common partial drive system 24, 25.
• the separation between the two relay systems takes place in the left and right direction of the longitudinal center axis 32 shown.
• the invention is not limited to the combination of the parts 33, 34 shown here.
• the invention relates to all the previously illustrated embodiments, which can now be arranged modularly one above the other, as was shown with reference to the superimposed parts 33, 34, each part 33, 34 being divided with respect to the longitudinal center axis 32 and each part (left side and right side) of the respective part 33, 34 has its own part drive system 24, 25.
• each partial relay 13, 14 is assigned a separate drive system, which is shown in the drawings as partial drive 24 and 25.
• FIG. 7 shows, as a deviation from the previously shown exemplary embodiments, that both the active contact spring and the passive contact spring are each guided to the outside with connections 3, 7 and 3 ', 7'.
• the break contact is looped into the monitoring circuit for starting the arrangement.
• the closer is used for self-holding. These contacts have to bear a much lower load than those available for external use. There is a potential for reducing the required volume here. The same applies to the insulation to the drive. The question of whether one connection of the internally usable closer should already be connected to a coil end differs from case to case.
• twin relay shown here is thus that simpler manufacture is ensured with the smallest space requirement, since external interconnections are omitted.
• the user has a great benefit from this because wiring errors are avoided from the outset and there is space on an existing circuit board for other applications and interconnection paths.
• the main advantage for the user is that two partial relays are actually arranged in a single housing, which can be controlled separately from one another, but are to be regarded as one piece in storage and processing, which considerably simplifies handling.
