Definitions

  • the present invention relates to a relay, in particular a small relay, with a spring bracket which serves to hold the magnetic coil and the contact spring set.
  • relays are often provided with flat plug connections, on the basis of which measure it is possible to use such relays in a very simple manner in existing electrical circuits, or to be able to replace them in the event of a fault.
  • the individual flat plugs are connected to the connections of the contact spring set with the aid of conductors arranged inside the relay, which have to be fastened to the connections of the flat plug and the contact spring set, for example by soldering.
  • a relay in particular a small relay, which has a greatly simplified structure in view of the existing, separate spatial conditions - in the connecting conductor to be routed separately within the relay can be dispensed with.
  • this is achieved in that the individual contact springs of the contact spring set 5 are provided at the bottom 5 with integrally molded tabs, which are guided through slots arranged in the bottom wall of the spring bracket and are fixed in position in this area both positively and positively.
  • the present invention is based on the knowledge that the intended contact spring set of the relay in question can be modified such that the line connections of the contact spring set provided in the interior of the respective relay normally come to lie on the outside of the relay, in which case the relevant line connections directly in Form of flat plug connections can be formed, so that the provision of arranged within the relay, separately to be laid connecting conductors can be dispensed with.
  • the position of the contact spring set with the one-piece molded flat plugs is expediently carried out within an adapter plate, which can be fastened to the bottom wall of the spring bracket of the relay in question using ribs and grooves.
  • the adapter plate provided must be designed in such a way that both the tabs to be located on the outside of the relay and the contact springs arranged on the inside of the relay are fixed in position with the aid of the same.
  • the positional fixation of these elements can take place either by extrusion coating, gluing or laterally pushing on the contact spring set provided with the flat plugs into slots provided within the adapter plate.
  • the slots or guide grooves provided within the adapter plate are expediently designed in a Z-shape, which on the one hand ensures a good position Locking of the individual contact springs with their tabs comes about, while on the other hand the mutual distance between the individual tabs is increased while maintaining a relatively small mutual distance between the individual tabs, which often appears desirable or necessary in view of the required insulation properties.
  • additional ribs or grooves are provided on the outside of the adapter plate, which run between the individual flat plugs.
  • the provided adapter plate is finally designed such that the relay can be attached within an electrical circuit using the provided adapter plate.
  • the small relay 1 shown in FIGS. 1-3 contains a drive system, the coil of which can be controlled via coil connections 29, 30.
  • the armature acts on a contact spring set, which consists of three contact springs 14 to 16.
  • These contact springs 14 to 16 are integrally formed with tabs 2, 22 protruding from the bottom surface of the relay.
  • the contact springs 14 to 16 thereby lead through slots 23 of a spring bracket 21 therethrough, and are straight or Z-shaped slots 7, 27 a p Ada terplatte 3 is fixed in position.
  • the adapter plate 3 serves to ensure that the plug-in forces acting on the flat connectors 2, 22 cannot be transmitted to the spring bracket 3 and thus to the contact springs 14 to 16.
  • a protruding tab 4 is provided on the central tab 22, which engages in a corresponding latching opening 5 in the region of the guide groove 27.
  • the adapter plate 3 can be pushed onto the spring bracket 21 of the small relay 1 in the plane perpendicular to the drawing plane of FIG.
  • the adapter plate 3 For the positive connection of the adapter plate 3 with the bottom surface of the spring bracket 21, it is provided that on the bottom surface facing side of the adapter plate 3 projecting ribs are present, which engage in corresponding grooves 3 on the bottom surface of the spring bracket 21.
  • projections 10 are provided with holes 6 provided in addition, by means of which not shown Fixed To g ungs- passage means with which the adapter plate can be mounted on any mounting face.
  • FIGS 4 to 6 show further details of the adapter plate 3. From these figures it can be seen that the slots acting as guide grooves 7 are Z-shaped, while the guide groove 27 is straight. In the area of the spring groove 7, 27, a latching opening 5 is provided, in which the respective tab connector 2, 22 with the tabs 4 projecting therefrom comes into engagement.
  • FIG. 7 shows a schematic, enlarged representation of the type of attachment of the adapter plate 3 to the contact springs 14 to 16 provided with tabs 2, 22.
  • the ribs 8 protruding on the rear side of the adapter plate 3 can be seen, which in corresponding grooves 9 in the Area of the spring bracket 11 of the relay 1 reach for intervention. It is clear from this that the contact springs 14 to 16 can be pulled out of the slots 23 of the spring bracket 11 at any time and can be replaced by contact springs of a different type.
  • the adapter plate 13 has grooves 13 on one side, the longitudinal extent of which extends parallel to the broad side of the flat plugs 2, 22, so that crawl plugs of increased length are formed between the flat plugs.
  • ribs 17 are formed in the material of the adapter plate, which engage in the not shown grooves in the spring bracket of the relay 1.
  • the contact springs 14-16 are also injected with their tabs 2, 22 into the material of the adapter plate 13, i.e. thus permanently connected to the adapter plate 13.
  • the contact springs 14 to 16 can also be fastened with their flat plugs 2, 22 by gluing.
  • an adapter plate 19 is provided, in which the central guide groove 27 is axially elongated by opening in the area of a wedge-shaped support 20 of the adapter plate 19. It can also be seen that the outer contact springs 14 and 16 are provided with tabs 12 which engage in the material of the spring bracket 21. This ensures additional securing of the position of the contact springs 14-16 in the area of the slots 23.
  • FIG. 10 shows a perspective, schematic view of a further embodiment of an adapter plate 31, which in this case consists of two plate parts 32, 33, which can be snapped together using corresponding locking elements 34, 35.
  • the individual flat plug with the molded contact springs, for example, the flat connector 22 are held firmly within the adapter plate 31, with the respective flat connector 22 being enclosed from all four sides, so that the intended flat connectors are extremely well fixed in position.
  • FIGS. 11 and 12 show a further embodiment of an adapter plate 41 to be used in the context of the present invention, which in this case is designed such that it can be plugged onto the small relay 1 provided with flat plug connections 2, 22 from below.
  • the individual tab connectors 2, 22 are completely surrounded by the adapter plate 41, so that excellent insulation of the individual tabs 2, 22 is achieved.
  • Z-shaped guide grooves or guide slots are also provided, in which the two outer flat plugs 2 come to lie.
  • the entry points of these guide grooves are designated 45.
  • latching lugs 42 are provided on both sides in the region of the guide grooves, which, when the adapter plate 41 is slid onto the tabs 2, 22, correspond to the tabs 22, 2 on the side g e-seen recesses snap into place.
  • the adapter plate 41 is provided in the region of the Z-shaped guide grooves with additional point supports 50, on which the angled regions of the flat connectors 2 come to rest, resulting in a exact positioning of this tab 2 comes in relation to the adapter plate 41.
  • the adapter plate 41 shown in FIGS. 11 and 12 has through openings 47 and 48 arranged in pairs in its lower region, the through openings 47 serving to lead the coil connections through and the through openings 48 serving to lead the end connections through.
  • the adapter plate 41 is additionally provided with ribs 49 and a latching tab 51, the ribs 49 serving to enlarge the crawling plugs resulting between the individual tabs 2, 22, while the latching tab 11 fastens the adapter plate 41 with the small relay 1 placed thereon allowed within electrical equipment.
