Definitions

  • An electromagnetic relay which is used to switch several independent contact groups is out EP 0 319 478 B1 is known.
  • the transmission of the anchor movement on the contact elements in this relay takes place via a U-shaped slider.
  • This slider is at the top of it Longitudinal leg directly onto the longitudinal anchor leg via snap noses hooked.
  • the slider longitudinal legs have sufficient flexibility to the locking mechanism enable.
  • the flexibility of the longitudinal slide leg appears disadvantageous in terms of mechanical strength of the relay.
  • the storage of the anchor and the attachment the armature spring is only on the coil former. Thereby a flat design can be realized, however at the expense of a rather extensive width.
  • the aim of the invention is automation-friendly design Precautions for a relay, which simplifies assembly the anchor spring and the anchor as well as an improved suspension enable the slide so that this the anchor movement redirects to the contact elements without play. Furthermore applies to the compact design and automated production favoring modular construction of the relay a special Attention.
  • this goal is achieved in that the Anchor with its cross leg unrollable on the free end of the core longitudinal leg is stored and at the end of it Longitudinal leg with the end of the core cross leg a working air gap forms, and that a U-shaped armature spring is provided which is with a first arm on the anchor longitudinal leg attached, approximately in the central section is arranged parallel to the anchor cross leg and with the second arm in a recess between the core and the bobbin is attached parallel to the longitudinal core leg.
  • the recess between the core and the bobbin is in one advantageous embodiment in the form of a separate space molded onto the bobbin. This can be done easily Realize in the manufacture of the bobbin, because the bobbin is preferably made as a molded plastic part is. In addition, the integration of the recess appears in the core much more complex.
  • the second arm of the armature spring which is in the recess is inserted between the bobbin and core with provided with a locking lug, which is embossed directly above is hooked in the core. This is an unintentional one Disassembly of anchor spring including the one firmly connected to it Armature on the one hand and coil body with arranged therein Kern, on the other hand, is not easily possible.
  • the Latch is preferably by punching from the spring plate and then bend so that they are non-positively and positively to the embossing in the core adjusts.
  • the at least one contact spring is parallel arranged to the coil axis, with a U-shaped slide, which is coupled to the anchor via the ends of its side arms is, with its central section, the at least one contact spring actuated, resulting in a compact design in particular for multipole relays.
  • Another advantageous Embodiment of the invention is the coupling of the Slider to the anchor over at the ends of the side arms of the Slider molded snap noses simplified. To do this are on the anchor spring on both sides preferably perpendicular to the longitudinal arm leg Oriented spring tabs molded in one piece, on which the snap noses are hooked.
  • the basic element with pockets for receiving preferably several of a contact spring and counter-contact elements existing contact sets By the side walls of the pockets are the individual contact sets isolated from each other. Furthermore are on the lower edge of the middle section of the slide facing downward Shaped actuators.
  • the number of actuators corresponds to the number of contact sets to be switched. This results in a space saving, since the actuating elements in contrast to a massive design of the slide middle section already housed in the pockets are. It can also be used for isolation the contact sets of sufficiently high side walls of the pockets with the compact design of the relay. Furthermore can the overtravel by the height of the actuators defined the contact springs with respect to the counter-contact elements will.
  • the actuators are simple on the preferably manufactured as a molded plastic part Molded slider.
  • Wear to increase the mechanical strength of the relay furthermore those integrated on the lower edge of the armature cross leg Retaining pins which form-fit the core and thereby secure the anchor against lateral displacement. Furthermore, one is fixed on the upper edge of a bobbin flange molded pair of guide elements Longitudinal anchor leg, which contributes to the stability of the arrangement low manufacturing overhead is increased.
  • Relay results in a very simple assembly process, which is also easy to use or specialized workers.
  • the basic body is preferred with the contact and connection elements Equipped to assemble the magnet system.
  • the anchor spring is preferably attached to the anchor in advance, for example by riveting.
  • the core is preferably first axially into the coil former inserted until the cross leg of the core at one Front side of the bobbin bears. Then the will Arm containing arm of the anchor spring into the recess inserted between the bobbin and core until the latch hooked in the core provided.
  • the slide is from below on the armature spring tab mounted, with which the assembly of the magnet system including the coupling of the slide completed is.
  • the last assembly step is just the magnet system and the base body connected to each other.
  • the relay according to the invention consists in its main components from a magnet system 1, one on the armature spring tabs 52 suspended slider 7 and a base body 6 and contact springs 61, counter-contact elements 62, contact connection elements 63 and winding connection elements 64 ( Figure 1).
  • a pair of upwardly extending angular guide members 23 formed, which the anchor 4 lateral Give hold and thereby increase the shock resistance of the relay.
  • FIG 2 illustrates the features of the invention Magnet system 1, which are used to attach the armature spring 5.
  • the coil body 2 is a flat cuboid free space 21 to recognize (see also Figure 4).
  • This free space 21 takes the arm of the armature spring 5, which the locking lug 51st contains and extends parallel to the armature cross leg 42.
  • the arm of the armature spring 5 equipped with the latch 51 is up to immediately before the through the space 21 in the coil body 2 formed stop inserted, and the latch 51 is in this position in the embossing 33 on the underside of the core 3 hooked in (see also Figure 3).
  • a yoke 34 is integrally formed on the cross leg 32 of the core 3. To reduce stray flux at the working air gap are yoke 34 and pole face 43 T-shaped widened.
  • the armature spring 5 is equipped with a pretension bend, through which the armature 4 is biased towards the yoke 34 is.
  • the suspension mechanism for the slide 7 is shown in FIG. 5 shown.
  • the armature spring 5 At the top of the armature spring 5 are on their free end on both sides perpendicular to the main axis of the armature spring 5 oriented spring tabs 52 formed, the spring tabs 52 first at an obtuse angle and immediately at the end are bent again at an acute angle so that the ends of the spring tab 52 have a prestress (see also also Figure 1).
  • the spring tabs 52 engage under the lower edges the molded at the end of the side arms 71 of the slide 7 Snap tabs 73, causing the stop shoulders 74 of the side arms 71 against the underside of the longitudinal arm 41 are pressed.
  • the side arms 71 of the slide 7 are also on both sides by a on the flank of the longitudinal arm leg 41 molded pair of guide lugs 44 which fix the ends of a side arm 71 reach around a lateral displacement of snap noses 73 and spring tabs 52 to one another to prevent. This is also the detachment of the slide 7 leaning forward. Furthermore, based on FIG the lower edge of the armature cross leg 42 formed retaining pin 45 to recognize which on the outer edges of the anchor cross leg 42 are integrally formed so that they form-fit the core reach around and additionally secure the anchor 4 on the side. Furthermore, on the lower edge of the middle section 72 Actuators 75 attached to the slider 7. The slider 7 is equipped with three actuators 75 since it in this embodiment, a slide 7 for a three-pole relay.
