Definitions

  • the present invention relates to an electromagnetic relay, in particular a miniature relay, according to the first part of claim 1.
  • Such a relay is known, for example, from DE-C-2 213 146 and DE-U-7 828 023.
  • the housing consists of several parts made of thermoplastic plastic which are glued or welded to one another, with recesses being provided in the two mutually parallel side walls are in which each protruding edge piece of the magnetic yoke engages in such a way that in a composite, for example welded condition the magnetic yoke is fixed in position.
  • thermoplastic products can only be manufactured within relatively wide tolerance limits.
  • the contact systems must also be adjusted according to the possible different installation position of the magnet system, also because of the possible different composition and, for example, welding of the housing parts. Because of the elasticity of the contact materials, this is relatively complicated and lengthy.
  • the object is to be designed to design a relay of the type mentioned in such a way that the adjustment of the contact system can be carried out quickly and easily with the required accuracy by changing the position of the actuator of the magnet system relative to the contact system.
  • connection elements 7 are formed in the side wall 3, which lead to the contact system 8 with connection point 9 protruding above.
  • a contact spring 10 is welded onto this, to which movable contact elements 11, 12 are attached, which cooperate with fixed contact elements 13 and 14, respectively.
  • a connecting element 7 is connected to the coil, not shown, of a magnet system 15, which still consists of the coil former 16, a coil core 17, a magnetic yoke 18 connected to the coil core 17, and a movable armature 19, which is designed as a hinged armature in the example.
  • the latter is pressed against the end edge 21 of the magnetic yoke 18 by means of a pressure spring 20 and is thus pivotably mounted.
  • the pressure spring 20 can be attached to the bobbin or molded onto it so that it forms a structural unit with it.
  • one leg 22 of the armature 19 rests on the magnetic yoke 18.
  • a plastic switching cam 23 attached to the armature 19 can actuate the end 24 of the contact spring 10.
  • Two such housing shells 1 form a housing part in which the magnet system 15 is fixed in position.
  • This housing part can also consist of more than two parts, for example as described and shown in DE-U-7 828 023.
  • two recesses 26 and 27 are arranged one behind the other at a distance.
  • a lateral extension 28 or 29 of the magnetic yoke 18 engages in these without play.
  • the lower surface 30 of the recesses 26, 27 each has a bulge 31 or 32 on which the shoulder 28 or 29 rests.
  • the contact point of the recess 26 provided on the left in FIG. 1 serves as a pivot point 33 for the magnetic yoke 18.
  • the magnet yoke 18 can be lowered in the recess 27 by pressing on the cover part 5 with a hot and / or ultrasound-loaded stamp, whereby the bulge 32 of the recess 27 softens and is pushed down. This process takes place with simultaneous measurement of the contact distance with switching cams 23 acting on the end 24 of the contact spring 10, e.g. by measuring the switchover point with the voltage applied to the contact system 8.
  • the stamp pressure is removed or the stamp is lifted off completely, so that the magnet system 15 in the adjusted position due to the cooled and hardened, deformed bulge 32 and the at this point is also firmly held down, cooled and hardened part 34 of the cover part 5 (Fig. 4).
  • the recess 27 with the bulge 32 to be deformed is advantageously provided in the region of the end edge 24 of the magnetic yoke 18 serving as the pivot axis, and the lugs 29 are also arranged at the end of the magnetic yoke 18.
  • a single cutout extending practically over the length of the magnetic yoke 18 can also be provided.
  • the entire lateral edge of the magnetic yoke 18 could lie in the recess.
  • the bulge 31 can also be formed by a corresponding shaping of the magnetic yoke 18 and the pivot point can thereby be determined.
  • the relay can be closed by a cover 35 and made wash-tight, for example by casting.

Claims (3)

1. Relais électromagnétique, en particulier relais miniature, comprenant un bloc de bottier en plusieurs pièces d'une matière thermoplastique, comportant deux parois latérales (3) qui s'étendent parallèlement l'une à l'autre et sont pourvues d'évidements (26, 27) dans lesquels s'étend sans jeu la culasse (18) par ses bords latéraux, de sorte que le système magnétique soit fixé en position lorsque le bloc de boîtier est assemblé, caractérisé en ce que la culasse (18) vue dans le sens longitudinal (25), s'appuie de chaque côté en deux points distants l'un de l'autre, chacun sur une saillie (31, 32) dans un évidement (26, 27) et en ce que, dans une première paire d'évidements (27) se faisant face, les saillies (32) formées par les parois latérales du boîtier (3) et celles qui leur font face de parties (34) des parois latérales du boîtier délimitant les évidements, sont déformables par l'effet de la chaleur et/ou d'ultrasons, ce qui provoque ainsi un basculement de la culasse (18) par rapport aux saillies (31) de la deuxième paire d'évidements, de sorte que, par ce positionnement de la culasse (18), la position de l'armature (19) soit ajustée par rapport au système de contacts (8) à actionner, la disposition de la première paire d'évidements (27) et la conformation des saillies qui s'y trouvent, avant toute déformation, étant telles que, le relais étant non excité, l'armature se trouve en position de travail.
2. Relais selon la revendication 1, caractérisé en ce qu'il est du type à armature basculante, l'armature basculante (19) étant supportée à pivot sur l'arête terminale (21) de la culasse (18), en ce que, la première paire d'évidements (27) dans les parois latérales duboîtier (3) est disposée dans le voisinage du bras (22) de l'armature basculante (19) appliqué contre la culasse (18), en ce que, le système de contacts (8) comprenant les ressorts de contact (10) s'étendant dans le sens longitudinal de la culasse (18) est disposé au-dessus de la culasse (18), en ce que la deuxième paire d'évidements (26) et, de ce fait, le point de pivotement (33) de la culasse (18) est située entre le point fixe (9) des ressorts de contact (10) et les contacts (11, 12, 13, 14) et en ce que l'armature basculante (19) attaque l'extrémité (24) desdits ressorts de contact (10).
3. Relais selon la revendication 1 ou 2, caractérisé en ce que le ressort de pression (20) de l'armature basculante (16) est monté sur la carcasse de la bobine (16) ou forme un composant d'une seule pièce avec celle-ci.
