Definitions

  • Said devices consist essentially of an electromagnet and a metal part capable of moving under the control of said electromagnet between two or more than two positions for the performance of any function specific concrete which can be, for example, the closing and opening of a conduit, electrical circuit etc.
  • a characteristic fundamental is generally the functional precision and, in this sense, we is constantly developing new creations, with a view to combining said characteristic of precision with the simplicity of construction and, in many cases, also with very small dimensions.
  • the document EP-A-0 278 064 describes a relay constituted by a containing carcass fitted with a closing base, however it is intended to inside a mechanism formed by an electromagnet and a moving part which is arranged in tilting mounting on a corresponding support.
  • This support consists in a leaf spring carried by a collar surrounding part of a shaped part of "U" constituting the core of the solenoid coil.
  • the tilting piece rests on the leaf spring and is pulled back by a coil spring which connects this tilting part to a basic part of the relay.
  • the tilting part can slide on the leaf spring during its movement, this which causes errors in the positioning of the tilting part and, therefore, variations in the contact points between the tilting part and the pole the electromagnet.
  • This relay object of the invention is essentially constituted by a containing carcass provided with a closing base which is fixed to the latter by means interlocking, however there is a functional assembly inside a basic part which defines in its own conformation the body for the coil electromagnet, which in turn has formations for attachment snapped onto the base, however, on said base piece, there is a small complementary part on which is incorporated, in tilting mounting, the mobile metal part which can be controlled by the electromagnet.
  • Said tilting metal part is disposed in tilting mounting on said complementary part in which it fits by a transverse axis integral and it is urged towards a spacing positioning relative to the electromagnet by a pulling spring incorporated between its rear part and the part of based.
  • This mounting promotes the nesting of the axis in the housing of the room tilting support and thus ensures constant positioning of the points of contact between the tilting part and the part constituting the core of the electromagnet.
  • the tilting support part is in turn fixed relative to the part basic even by means of the element which defines the core of the electromagnet, which is made up of a U-shaped piece which is positioned in contact with a magnet permanent which fits in the base.
  • the relay object of the invention certainly has very advantageous characteristics which confer to its realization a clean life by itself and a preferable character compared to conventional relays.
  • Figure 1 shows an exploded perspective view of the assembly constituting the relay that we recommend.
  • Figure 2 is a side view in section of the relay assembly, where we have shown in broken lines interrupted the functional elements of the mechanism interior.
  • Figure 3 is an enlarged detail of the locking locking snaps in the assembly of the basic part in which the coil body of the electromagnet is incorporated, relative to the base.
  • Figure 4 is a side view of the mechanism of the relay in the armed position.
  • Figure 5 is a representation similar to the previous, with the mechanism in the disarmed position.
  • Figure 6 is a perspective detail of the part in "U” constituting the core of the electromagnet, in correlative positioning relative to its nesting in the support room, where you can see the formations corresponding snap in said socket.
  • Figure 7 is an enlarged detail showing the arrangement of one of the connection terminals and the winding on this terminal of the wire which comes from the coil of the electromagnet.
  • the invention relates to a relay of the kind of those that we use as a functional device for various control and command functions in installations electric, said relay being essentially constituted by a functional mechanism which is housed inside a carcass (1), which closes by means of a base (2).
  • the base (2) is provided with a wall fitting into the carcass (1) and, on the external part of this interlocking wall, protrude formations prominent (3) tooth-shaped, which are likely to fit into corresponding windows (4) from the wall of the carcass (1), forming a snap locker of the closure in the assembly.
  • the functional mechanism of the interior consists, for its share, in a conventional manner, of an electromagnet (5) and a movable metal part (6) which can be controlled by this one but, in a way that conforms to the solution recommended, said movable part (6) is arranged in assembly tilting, on a support piece (7), being further requested in attraction, from its rear part, by a spring (8), relative to a base part (9) on which is located the support piece (7) mentioned, so that, under the action of the cited spring (8), this movable part (6) tends keep away from the electromagnet (5).
  • the aforementioned basic part (9) which, like the carcass (1), the base (2) and the support part (7), is made of an electrically insulating synthetic material, defines, unitarily with it, a formation (10) constituting the coil body for winding the coil (11) corresponding to the electromagnet (5).
  • Said part (9) further defines formations side (12) by means of which it is capable of establishing a fixing snap in the assembly, relative to two windows (13) corresponding to the socket wall the base (2), as can be seen in Figure 3; this part (9) defining on the other hand wings horizontal projections (14) with which it rests on the upper edge of the mentioned interlocking wall of the base (2), said wings (14) being in turn retained in the mounting by the carcass (1), as can be observed in Figure 2; this way, we get a montage completely blocked from the whole, which allows maintain with total accuracy fixed distances in mounting, thus obtaining an exact positioning and stable functional elements and, consequently, a high operational precision of operation.
  • the core of the electromagnet (5) is formed at its tower by a metal part (15) in the shape of "U", which fits axially by one of its branches through the coil body (10) of the electromagnet (5), defining the actual nucleus thereof; while the other branch of said piece (15) passes through an opening (16) of the base part (9), fitting on the other side in a housing (17) defined by the support part (7); of so that, by means of this piece (15), it is established at the both the attachment of the support piece (7) cited and the formation of the functional core of the electromagnet (5).
  • Said part (15) which rests on a magnet permanent (18) which is arranged on the base (2).
  • the part (15) mentioned also has an imprint (22), in the internal face of its socket branch in the support piece (7), while the respective wall of the support piece (7) cited has a protuberance corresponding (23); so that when nesting said branch of the part (15) in the housing (17), it in addition, a snap-in is established which ensures mounting stability; provided that between the protuberance (23) and the imprint (22), there is a slight phase shift vertical, so that when establishing the locking block mentioned, it is created by the effect clean of it, an effort on the part (15), towards the high, thus avoiding any possible play of mobility of this part in relation to the exact position of mounting for correct support of the tilting part (6) in this piece.
  • the part tilting (6) consists of a small plate rectangular in shape of a pallet, which has an axis transverse (19) which is joined therein solidly, for example, by laser welding, so that the precision dimension of the assembly is determined by the tooling welding, said axis (19) fitting at its ends in corresponding sockets (20) of the support part (7), which serve as rotational supports for tilting.
  • the electromagnet (5) when, in this situation, the electromagnet (5), is activated by a current supply to the coil (11), the magnetic flux that the core part (15) acquires in consequence is opposed to that created by the magnet (18), which causes the attraction force on the part (6) to decrease, it tilts accordingly under the effect of tension spring (8) on the rear part of the latter, to a position away from the electromagnet (5), as seen in Figure 5, from which, for find again the armed position of figure 4, it is necessary, once the current from the coil (11) has disappeared, push the workpiece (6) against the spring tension (8), up to contact with the electromagnet (5), which is why there is a pivot (21) which appears through the carcass (1) with which the actuation of the thrust mentioned.
  • the arrangement of the spring (8) is provided so that it is inclined towards the interior from its attachment on the part (6) to the antagonistic fixing on the base part (9), so that in additional traction for tilting functional of the part (6) mentioned, said spring (8) also determines a tension that promotes the nesting of the axis (19) in the housings (20), thereby establishing a security in maintaining the assembly of the assembly.
