Definitions

  • Said devices consist in principle of an electromagnet and a metal part capable of being moved under the control of the latter between two or more than two positions for the accomplishment of any specific concrete function which can be, for example example, closing and opening a conduit, etc.
  • This relay object of the invention is essentially constituted by a containing carcass provided with a closing base and means serving to fix it at the place of application, while there is inside a functional unit formed of a basic piece that forms in its own conformation of the body for the electromagnet coil, and by a complementary part on which is disposed, in tilting assembly, the movable metal part which can be controlled by the electromagnet, which is biased towards a normal spacing position relative to the electromagnet by a tension spring incorporated between itself and the support piece, said support of the mentioned tilting piece being itself secured to the base piece by the very element which forms the core of the electromagnet, which consists of a "U" shaped piece, which is positioned in contact with a permanent magnet housed in the base.
  • this recommended relay certainly has very advantageous characteristics which give its realization a life of its own and a preferable character compared to conventional relays.
  • the object of the invention consists of a relay of the type that is used as a functional device for carrying out various control and command functions in electrical installations, said relay being essentially constituted by a functional mechanism which is found housed inside a carcass (1), which, according to an exemplary embodiment, is closed by means of a base (2) which is fixed by interlocking of lateral pins (3) in corresponding orifices (4 ) of the carcass (1), however, that the latter is in turn provided with formations (5) for fixing, by screwing or any other similar means, to the place of application.
  • the functional mechanism consists, in turn, in a conventional manner, of an electromagnet (6) and a movable part (7) which can be controlled by it but, in particular, said movable part (7) being arranged in a tilting arrangement, mounted on a respective support (8) with respect to which it is also attracted at its rear part by a spring (9) which tends to keep it separated from the electromagnet (6) as can be seen in Figure 2.
  • Said mechanism further comprises a base part (10) which, like the carcass (1), the base (2) and the support (8), is made of an insulating synthetic material, this base part (10 ) forming a flat plate-shaped body, on which rises an integral formation (11) which constitutes the coil body for the winding of the corresponding coil (12) of the electromagnet (6).
  • the core of the mentioned electromagnet (6) is in turn constituted by a metal part (13) in the shape of a "U", which is axially fitted by one of its branches through the coil body (11) , forming the core proper, while the other branch passes through a respective opening (14) of the flat body of the part (10), fitting on the other side into a housing (21) defined by the support (8) of the tilting part (7), so that, by means of said part (13) which constitutes the core, it establishes both the fixing of the support (8) mentioned and the formation of the functional core of the electromagnet (6) mentioned; the part (13) mentioned being placed in abutment on a permanent magnet (22) which is housed in the base (2).
  • the tilting part (7) mentioned consists of a metal plate (15) in the form of a pallet and a supporting part (16) in the shape of a "U", the two being joined together by fixed fixing by stamping. , spot welding or any other conventional form, said load-bearing part (16) defining a small formation (17) in its upper part, for the attachment of the spring (9) in the tension thereof relative to another reciprocal attachment formation (18) defined in the support (8); while, laterally, this part (16) forms small pins (19) which serve as tilting axes for mounting on the support (8), in the sense that the latter fit into corresponding housing notches ( 20).
  • FIG. 4 an example of embodiment of a shape in which the base (2) forms a wall (24) nesting in the carcass (1), while on the outside of said wall (24), protruding protrusions (25) , which are capable of fitting into corresponding windows (26) of the wall of the carcass (1), to establish the fixing of the closure in the assembly; while the base part (10), which comprises the coil body (11), in turn forms in its sides formations (27) by means of which it can establish a fixing snap in the assembly, on respective windows (28) of the wall (24) of the base (2), as can be seen in FIG.
  • this part (10) further forming projecting horizontal wings (29) with which it bears on the upper edge of the wall (24) of the base (2), so as to be in their turn blocked in the assembly by the carcass (1), as can be seen in FIG. 5, so that a completely fixed assembly of all is obtained 'the whole relay; by allowing fixed distances to be maintained inside the assembly, so that an exact and stable positioning of the elements of the mechanism is obtained and the subsequent obtaining of high operating precision.
