Definitions

  • the present invention relates to a relay, in particular a small relay, with an insulating body serving to hold the magnetic coil and the contact springs.
  • relays are often equipped with flat plug connection elements, which makes it possible to use such relays in a very simple manner in already existing electrical circuits, and to simply replace them in the event of a fault.
  • connection of such flat plugs to the respective connections of the contact spring set takes place, for example, with the aid of conductors arranged inside the relay, which are fastened to the connection-side ends of the flat plug and the contact springs, for example by soldering.
  • US-A-3 878 489 discloses an arrangement in which the connecting lugs of the contact springs, which are led out of the relay base plate as a spring bracket, are inserted into a printed circuit board with plug pins on opposite sides and are soldered to the latter, the plug pins of which are received in a plug-in base
  • the printed circuit board in turn is inserted into tubular plug connection elements of the plug base and are fixed by soldering.
  • the aforementioned document shows a solution for a relay as a plug-in module so that the forces occurring during the plugging process, both longitudinally and at an angle to this axis, are largely kept away from the already adjusted contact sets.
  • connection spring sets with integrally molded connection elements in the form of soldering or plug-in connection lugs and fixing them in a so-called spring bracket
  • these connection lugs one defining the entire relay to another Grip the object as well as the base plate serving as a comprehensive protective cap in molded-in slots.
  • the base plate is rigidly attached here via pins on the spring bracket, and thus forms a rigid mounting of the connecting ends of the contact springs projecting from the spring bracket against tensile and shear forces acting laterally at an angle to the longitudinal axis of the contact springs, while forces acting on the connecting lugs in the longitudinal direction occur solely on the spring bracket the Einspannelemen t e should be intercepted.
  • Such a base plate consequently shows no solution to give the anchoring base a small relay to be designed as a plug-in connector with connecting lugs integrally formed on the contact springs in the form of flat plugs, in order to adjust the tensile and thrust forces, which occur particularly during the plug-in process as well as the disconnection process, as adjusting forces from the tight tolerances Keep contact springs away.
  • DE-A - 2 058 864 discloses a further possibility for fixing relay contact springs with integrally molded connection elements on a base or carrier plate, in which a so-called funnel plate is plugged onto the connection-side ends of the contact springs, which serves to center these projecting ends, this protects mechanically, and also forms an intermediate layer for the assembly of the contact spring set or the relay on a printed circuit (circuit board).
  • the present invention is therefore based on the object of creating a relay, and in particular small relay, which, compared to the known relays with only loose, centering guidance of the connection elements in molded openings correspondingly designed base plates, has its own, the predetermined crowded spatial relationships of such a relay type taking into account the positional fixation of the connection ends or connection elements of the contact springs by force and positive engagement.
  • connection elements are designed as flat plugs and are non-positively and positively fixed in the passages of the adapter plate.
  • the position of the contact springs with the one-piece molded tabs is thus in the insulating body and in the adapter plate, which can be fixed on the bottom of the insulating body.
  • the adapter plate is designed in such a way that, in this basic embodiment, the terminal-side tab connectors and the contact springs themselves are fixed in position with the aid of the same.
  • the tabs can also be fixed in the adapter plate by injection molding.
  • the passages on the adapter plate can be designed as guide slots that are open on one side, such that the tabs can be inserted into the adapter plate from the side.
  • the adapter plate can consist of two longitudinally extending, mutually lockable partial plates, which can be pushed onto the tabs of the contact springs from both sides.
  • the tabs of the contact springs are bent in a Z-shape in a special embodiment of the invention, and the passages of the adapter plate are shaped accordingly, which on the one hand achieves an additional positional fixation of the individual contact springs, and on the other hand the mutual distance between the individual Flat connectors of the relay is enlarged, which sometimes appears desirable or even necessary on the outside with regard to the insulation properties for increasing the air and creepage distances.
  • the tabs in particular the middle tab, run essentially straight and the position fixation in the adapter plate is effected by providing a latchable tab on the tab, a slight bend or a wedge-shaped projection on the adapter plate.
  • the adapter plate can also be fastened to the bottom surface of the insulating material body by means of ribs formed on it.
  • ribs or grooves are additionally provided on the outside of such an adapter plate, which serve to enlarge the creepage distances between the tab connectors which are integrally formed on the connection spring elements.
  • the adapter plate can also be designed according to a predetermined grid for connection to a printed circuit board.
  • the small relay 1 shown in FIGS. 1 to 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 in this form of representation is composed of the contact springs 14 to 16.
  • These contact springs 14 to 16 are formed in one piece with tabs 2, 22 protruding from the bottom surface of the relay.
  • the contact springs 14 to 16 are an insulating body 21 in slots 23 penetrating the bottom of the insulating body 21 in straight or Z-shaped passages or guide slots 7, 27 of an adapter plate 3 assigned to this side fixed in position.
  • the adapter plate 3 serves to keep the pushing and pulling forces acting on the tabs 2, 22 during the plugging process away from the insulating body 23, and cannot be transmitted to the integrally formed contact springs 14 to 16 of an adjusted contact set. This is achieved, for example, for the central tab connector 22 by providing a projecting tab 4 which engages in a corresponding latching opening 5 in the region of the passage or guide slot 27.
  • the adapter plate 3 is designed to be slidable perpendicular to the plane of the drawing in FIG. 1 onto the spring bracket of the small relay 1 in the form of an insulating body 21.
  • insulating body 21 For the positive fixing of the adapter plate 3 on the bottom surface of the insulating material body 21, it is provided that on the side of the adapter plate 3 facing the bottom surface, projecting ribs 8 are to be engaged, which engage in appropriately designed grooves 9 on the bottom surface of the body 21.
  • lugs 10 are additionally provided with holes 6, through which fastening means, not shown, are passed, by means of which the adapter plate 3 can be fixed on any fastening surface.
  • FIGS 4 to 6 show further details of the adapter plate 3. From these figures it can be seen that the slots forming the guide grooves 7 are Z-shaped, while the guide groove 27 is designed to lead straight through. In the area of the guide grooves 7, 27, a latching opening 5 is provided, in which the respective tab connector 2, 22 with the tab 4 comes into engagement.
  • FIG. 7 shows schematically in an enlarged view the form of fastening the contact springs 14 to 16 and their integrally molded flat connectors 2, 22 with an adapter plate 3.
  • the ribs 8 projecting on the back of the adapter plate can be seen, which correspond to the corresponding ones Grooves 9 come into engagement in the region of the insulating body 11 of the relay 1.
  • the contact springs 14 to 16 can therefore be pulled out of the corresponding slots 23 of the insulating material body 11 at any time and exchanged for contact springs of a different type.
  • an adapter plate 13 has grooves 18 on one side which run parallel to the broad side of the tabs 2, 22, so that creepage distances of greater length are formed between the tabs 2, 22.
  • the grooves 18 13 ribs 17 are formed in the material of the adapter plate, which engage in grooves not shown in the insulating body of the relay 1.
  • the contact springs 14 to 16 with their molded-on tabs 2, 22 are also injected into the material of the adapter plate 13 d. that is, permanently or permanently connected to the adapter plate 13.
  • the contact springs 14 to 16 can also be fastened with their integrally molded flat connectors 2, 22 by gluing.
  • another adapter plate 19 which has an axially elongated central guide groove 27 which opens into the region of a wedge-shaped, projecting support 20 of the adapter plate 19.
  • the outer contact springs 14 and 16 are provided with tabs 12 which engage in the material of the insulating material body 21. This measure represents an additional position fixation for these contact springs in the area of the slots 23.
  • FIG. 10 shows schematically in a perspective view a further embodiment of an adapter plate 31, which in this case consists of two partial plates 32, 33, which can be connected to one another by means of molded-on locking elements 34, 35.
  • the individual tabs for example the tabs 22, which are integrally formed on the contact springs, can be permanently fixed in the adapter plate 31, the tab connector 22 in question being enclosed on all four sides, so that the molded tabs are properly 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 is designed in such a way that it can be plugged onto the small relay 1 provided with flat plug connections 2, 22 from below.
  • the individual flat plug connection elements 2, 22 are completely encompassed by the adapter plate 41, so that excellent insulation of the individual flat plugs 2, 22 is ensured.
  • Z-shaped guide grooves or passages 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 in the guide grooves on both sides, which latch when the adapter plate 41 is pushed onto the flat plugs 2, 22 in corresponding recesses provided laterally on the flat plugs 2, 22 intervention.
  • the adapter plate 41 is provided in the area of the Z-shaped guide grooves with additional point supports 50, on which the angled areas of the flat plugs 2 come to rest, this flat plugs 2 being fixed in position with respect to the adapter plate 41.
  • the adapter plate 41 shown in FIGS. 11 and 12 has through openings 47, 48 arranged in pairs in its lower region, the through openings being used for the coil connections and the through openings 48 being used for the ground connection.
  • the adapter plate 41 is additionally provided with ribs 49 and a latching tab 51, the ribs 41 serving to increase the creepage distances between the tabs 2, 22, while the latching tab 51 attaches the adapter plate 41 with the small relay 1 placed thereon within an electrical one Devices.
