Definitions

  • the invention relates to an electromagnetic relay of the type specified in the preamble of claim 1.
  • the invention specified in claim 1 is based on the object to remedy this situation and to provide a solution consisting of a few components which does not require any additional connecting elements.
  • a carrier plate for functional elements inserted between the base plate and the yoke carrying the drive coil can be inserted in a corresponding manner without affecting the assembly properties of the relay as a whole.
  • the arrangement according to the invention is particularly favorable when using a transverse coil, which in particular actuates two folding anchors, which in turn act on spring contacts, the spring tongues of which are aligned parallel to the base plate.
  • the electrical contact elements leading to the outside are arranged in the immediate vicinity of the contact springs, and on the other hand, the drive and transmission parts can be easily inserted or snapped in from above.
  • the finally attached housing cap fixes the drive parts in their position and thus forms a safeguard against unintentional loosening components.
  • a stop provided on the housing cap secures its defined position.
  • the base plate is preassembled and an intermediate carrier plate, in which additional transmission elements are guided, is mounted.
  • the intermediate support plate has cheeks that form a "U” and are inserted between the corresponding cheeks of the base plate.
  • the yoke with its webs, which give it an overall H-shaped structure, is inserted into recesses in the upper region of the side cheeks of the base plate, so that the intermediate carrier plate is held at the same time.
  • the U-shaped cheeks of the intermediate carrier plate are designed so that they rest in aer operating position by means of (plastic) springs as compensating elements on the underside of the yoke and the intermediate carrier plate is thus clamped between the base plate and the yoke - which is due to the corresponding local arrangement of the Allows recesses to accommodate the web-shaped ends of the yoke cheaply allow.
  • the ends of the webs of the yoke allow a slight displacement thereof in the direction of aer webs, the web ends being able to pass through the cutout.
  • This mobility is favorable for the assembly of the yoke, so that no or only a slight deformation of the plastic part forming the base plate is necessary to snap the web ends into the recesses in the side cheeks of the base plate.
  • the movement of the cap in the direction of "putting on” is limited by projections on its inner surfaces, which interact with the upper end surfaces of the side cheeks of the base plate. In this way, all fixed components are mutually locked in a stable manner in the assembled state of the relay, but can be easily removed within a short time after removing the cap. Manufacturing tolerances are absorbed by the elastic materials or the spring elements provided at the interfaces.
  • the solution according to the invention is particularly advantageous for symmetrical double-armature relays with a horizontally arranged coil.
  • the base plate 1 is U-shaped and accommodates the connections 2 designed as flat plugs for contacts and drive of the relay.
  • two make contacts consisting of a fixed contact 3 and a movable spring contact 4 are provided as contact sets.
  • the two sets of contacts are each housed in a chamber divided by a vertical partition 5.
  • the wall surrounding the internal connections of the flat plugs meandering or under the division of chambers, so that their electrical separation is ensured.
  • the meandering partition contributes significantly to the strength of the base plate 1 of the relay forming a base group, the wall 5 on the one hand connecting element of the side walls 6 and 7 of the diode part and on the other hand serving as a support surface for further horizontally extending elements to be used between the side walls.
  • the side walls 6 and 7 are reduced in their wall thickness compared to the wall thickness in the area of the partition walls 5, so that they have an elastic spring effect when made from plastic.
  • a cover plate 8 Placed on the base plate 1 - or inserted between the side cheeks 6 and 7 of the base plate 1 - is a cover plate 8, which likewise has a U-shaped contour and is supported on the side cheeks 6 and 7 with the lateral legs of the "U".
  • the cover plate 8 has passages 9 and 10 on the one hand, which actuate the contact spring sets 4 in the Allow the area of the base plate through the cover plate 8 by means of intermediate members forming pimples 11 and 12.
  • the passages 9 and 10 are provided with cylindrical, downward-facing lugs 9a and 10a.
  • the upward-facing cylindrical projection 13 has a recess 14, which is cut for part of its diameter in the region of the surface of the cover plate 8 and which allows a spring element 15, forming a locking element, with symmetrically bent ends, through the cylindrical element 13 the pimple 11 reach tangent and penetrate within the cross section of the bore 9 in the recess provided there to block the movement of the pimple in the axial direction.
  • the side legs 16 and 17 of the "U" of the appropriately shaped Abqeckplatte 8 have at their upper ends semi-circular molded spring elements 18 and 19 or 20 and 21, which in terms of their height in the assembled state of parts 1 and b in the relaxed case up to Extend recesses 23 and 24 or 25 and 26 and secure elements engaging in these recesses against displacement.
  • the cover plate 8 thus simultaneously forms an upper cover for the electrical contacting elements or connecting lugs of the flat plug 2, so that the electrical insulation values can be maintained here without additional measures.
  • Lugs 27 and 28 which the lateral legs forming the "U" across the horizontal plane of the cover plate 8 Extend downwards and engage in the corresponding recesses in the base plate 1, secure the two workpieces 1 and 8 in the pre-assembled state against lateral displacements.
  • the drive element for the contact sets of the relay shown here is a magnet column 47, which is formed by a winding of enamelled copper wire on a coil former 29 and an iron core 30.
  • a yoke 31 is connected to the bobbin 29 and has at its ends extending in the longitudinal direction of the bobbin 28 web-like projections 32 and 33 or 34 and 35, which are each directed in pairs in parallel and form a U-shaped structure in the horizontal plane. which is to be regarded as "H" -shaped if all the webs 32 to 35 and the yoke are viewed together.
  • the approaches 32 to 35 make it possible to mount the coil carrier with the further drive elements for aie contacts in a particularly simple manner.
  • the side cheeks 6 and 7, as legs of the U-shaped base plate 1 are bent up laterally and, after the cover plate 8 has been inserted, the yoke 31 with the coil 47 is inserted.
  • the web-shaped lugs 32 to 35 of the coil body are secured in the recesses 23 to 26 of the side cheeks 6 and 7 of the base plate 1 by the curved spring lugs 13 to 21 of the cover plate against lateral displacement.
  • the relay can also be removed non-destructively at the same time, so that, if necessary, re-hiring can be carried out at any time.
  • a cup-shaped housing cap 36 is dimensionally adapted to uie outer dimensions uer base plate 1 and wira put over the side cheeks 6 and 7, where they are kept free of play i. 3 t.
  • the yoke 31 is laterally limited and held in the center by the cup-shaped housing cover 36, so that the yoke is automatically centered when the cup-shaped housing cover 36 is put on.
  • Angled anchors 37 and 38 are provided on both sides of the core 30 and are rotatably supported between the web-shaped projections 32 and 33 or 34 and 35. Since the anchors form an angle which is slightly greater than 90 °, flags 39 and 40 provided at their lower angled ends act on the upper sides of the sticks 11 and 12 and thus actuate indirectly the contact sets located on the base plate.
  • the two anchors 37 and 38 are folded and pivoted by means of "E" -shaped spring elements 41, the spring element 41 being shown separately in FIG. 2 to the right of the coil body.
  • the two anchors are laterally inserted between the web-shaped projections 32, 33 and 34, 35 when assembling a complete coil armature element.
  • the two anchor parts can be made identical, but the flags 39 and 40 lie side by side in the plane and are spatially adjacent to the two pimples 11 and 12 for power transmission.
  • the "E" -shaped spring element 41 is inserted from above between the web-shaped projections 32 and 33 b between 34 and 35, the webs having steps 50 in the direction of the outside, behind which the outer legs of the "E" -shaped spring element are supported.
  • the middle leg of the "E” protrudes due to its spring force from the plane of the other two legs in the direction of the armature and has an elongated extension 42 which is slightly angled or bent in the direction of the armature 37.
  • the attachment 42 lies against the cuckoo side of the outer surface of the armature, which is sharply rounded for angling, and secures it against falling outward.
  • the anchor itself has in the area of its sharp bend in the vicinity of the webs 32 and 33 (or 34 and 35) recesses, which are limited by steps 51 to the recesses 50 between the webs 32 and 33 and thus between these webs Secure the inserted anchor against falling out or unintentional shifting.
  • the spring element 41 forms a substantially force-free limitation of the mounting of the respective armature but is held in position by the pretensioning of the middle leg of the "E" and is countered by the bend 42 Secured falling out.
  • the anchors are secured in their position by inserting a single element which can be inserted from above, with the need for more cumbersome other storage means such as axles and the like.
  • the storage formed in this way can also be dismantled again without difficulty, if necessary, with a single movement, the production being able to be carried out expediently with any degree of automation.
  • a further embodiment variant, not shown, which fulfills its purpose accordingly, can be realized in that, leaving out the middle leg of the "E" of the spring element, the two outer legs are angled in the area of their outer ends on the inside, as is approximately the end 42 corresponds to the middle leg.
  • the relay presented as an exemplary embodiment is equipped with two separate armatures 37 and 38, which are attracted together when the coil is permeable to current.
  • the contact sets driven by the two armatures are operated together.
  • the two contact sets, each containing normally open contacts are connected in series and open together when the armature drops, so that the two air gaps created between the contacts open Prevent current flow for each.
  • the air gaps when the contacts are open are dimensioned so that they each ensure a shutdown. If it should happen that one of the contacts welds or one of the anchors sticks during the operating time of the device, the current is switched off by opening the other set of contacts.
  • FIGS. 3a to 3c The effect of the two sticks 11 and 12 in cooperation with the spring element 15 and a stop rivet 13 is shown in more detail in FIGS. 3a to 3c.
  • the stop rivet 13 is located on the top of the cover plate forming the intermediate carrier plate and is generally only visible in FIG. 1.
  • the embodiment of the invention is not limited to the preferred exemplary embodiment specified above. Rather, a number of variants are conceivable which make use of the solution shown, even in the case of fundamentally different types.
