Definitions

  • the invention relates to an electromagnetic relay with an excitation coil carried by a coil body, the coil body being carried by a base body made of insulating material arranged below the coil.
  • the object of the invention is to provide a relay of the type mentioned at the outset, which can be designed with parts which are easy to manufacture and assemble, a favorable division of space between the magnet system and a contact arrangement which can be actuated via the armature being made possible.
  • this object is achieved in a relay of the type mentioned at the outset in that contact connection elements are anchored in one plane in the base body, exposed sections being bent downwards as connecting lugs or upwards as contact carriers or spring supports.
  • the contact elements only require short bushings to the connecting pins. This has the advantage of a small space requirement and low contact circuit resistances.
  • the coil body is carried by a base body made of insulating material arranged below the coil, wherein the two parts can be connected via interlocking openings and deformable pins.
  • the connection elements are punched out of a circuit board and embedded together in one plane, exposed sections of these connection elements being bent as connection lugs to the underside of the base body or as contact carriers to the top side of the base body.
  • a bobbin 1 with a winding 2 has an axially continuous opening 3 for receiving a yoke arrangement, which is formed by two L-shaped angled yokes 4 and 5 and an intermediate permanent magnet 6.
  • the permanent magnet 6 is polarized in the direction between the two yokes 4 and 5, so it forms a pole face with each of these two yokes.
  • the long yoke legs 4a and 5a are inserted together with the intermediate permanent magnet 6 into the opening 3 of the coil body, so that their free ends lie in the coil flange 1a and can accommodate the short leg 7a of the armature 7 between them.
  • the armature 7 is L-shaped in the same way as the two yokes 4 and 5, and it is arranged with its ends between the yoke ends during assembly so that the yokes and armature together form approximately a rectangle. 7b so is the short armature leg between the free ends of the long yoke legs 4a and 5a, and forms with these respective magnetic coupling surfaces, while the long armature leg 7a between the free ends of the health - is arranged zen yoke leg 4b and 5b, and in each case forms operating air gaps with respect to these.
  • the armature 7 is mounted on the coil flange 1a via a U-shaped bearing spring 8, the central part of the bearing spring being connected to the armature and the two side parts each being fastened to the coil flange 1a.
  • the armature has an axis of rotation which runs perpendicular to the coil axis in the direction of the short armature leg 7b and enables the armature leg 7a to move between the yoke legs 4b and 5b.
  • a contact slide 9 which can be attached, for example, to the armature leg 7a or molded on by overmolding, serves to actuate two contact springs 10 and 11, which each form a changeover contact with the fixed contact elements 12 and 13 or 14 and 15.
  • the contact elements 12, 13, 14 and 15, as well as the spring supports 10a and 11a, are embedded or inserted into a base body 16.
  • This base body 16 carries the coil body with the yoke legs and the armature.
  • recesses 16a and 16b are provided in the base body, into which the free ends of the short yoke legs 4b and 5b are inserted.
  • the coil flange 1a is also seated on the base body 16 and can be connected to it by suitable measures. He has one in the usual way inserted or injected coil connecting pins 17, which are inserted through corresponding holes in the base body during assembly. A cap 18 is placed over the coil body 1 and the base body 16, wherein the joint between the base body and the cap and the leadthroughs of the connecting pins can be sealed with casting resin.
  • FIGS. 2 to 4 A detailed construction of the relay according to the invention is shown in FIGS. 2 to 4 in different sectional views.
  • two L-shaped yokes 34 and 35 each with their long legs 34a and 35a, are inserted into a coil former 31, together with an intermediate permanent magnet 36.
  • This permanent magnet is in the direction between the two yoke legs 34a and 35a polarize and extend over the entire length of the coil interior.
  • the yoke legs 34b and 35b which are angled outside the coil body, extend substantially perpendicular to the coil axis along the coil flange 31b and form two pole faces 34c and 35c for an armature 37.
  • the armature 37 is also L-shaped, its long leg 37a lying below the coil and with its free end between the yoke legs 34b and 35b and executing switching movements in the air gap formed thereby.
  • the upper end of the short armature leg 37b lies between the free ends of the yoke legs 34a and 35a.
  • the armature leg 37b is coupled on one side to the yoke leg 35a; this means that this is a monostable embodiment.
  • the free anchor end would rest against the yoke leg 34b in the idle state. 4, on the other hand, shows the state after excitation of the system; the anchor therefore rests against the yoke leg 35b in the working position.
  • the armature leg 37a has an angled cross section with an angled part 37d in order to obtain a sufficiently large flow guide cross section with a reduced overall height of the relay.
  • the armature is fastened with its short leg 37b via an armature spring 28.
  • the armature spring 28 itself is inserted into slots 38 of the bobbin flange 31a and fastened by means of the locking tabs 24.
  • the armature actuates the two center contact springs 40 and 41 via a molded slide 39, which, with their contact-carrying free ends, can be switched between two mating contact elements 42 and 43 or 44 and 45.
  • the mating contact elements 42, 43, 44 and 45 like the contact carriers 40a and 41a for the contact springs 40 and 41, are anchored in a base body 46 and form solder tabs 40b, 41b, 42b, 43b, 44b and 45b which protrude downward from the base body 46.
  • the contact elements are stamped together with their connecting lugs from a circuit board and embedded in the base body 46 in one plane with their respective central sections 40c, 41c, 42c, 43c, 44c and 45c.
  • the connecting lugs or solder lugs 40b to 45b are bent downward from these embedded central sections and the contact spring carriers 40a and 41a or the contact carriers 42 to 45 are bent upward.
  • the contact pieces, for example 42a and 43a, can be attached to the contact carriers before or after embedding.
  • the coil former 31 is fastened to the base body 46 with the yokes 34 and 35 and the armature 37.
  • recesses 46a and 46b are provided in the base body, into which the ends of the yoke legs 34b and 35b are inserted, and they via the contact walls 46c and 46d the anchor stroke at a precise distance from the cones limit clock elements.
  • the base body 46 has openings 47 and 47a for receiving fastening pins 48 and 48a, which are integrally formed on the coil body 31. These pins 48 and 48a can be thermally deformed after assembly in order to establish a firm connection between base body 46 and coil former 31.
  • openings 49 are provided in the base body 46 for receiving the coil connecting pins 50 anchored in the coil body.
  • a getter pocket 51 for receiving a liquid getter 52 is also integrally formed on the base body.
  • This getter substance is introduced in liquid form and solidifies into a getter-active mass.
  • retaining webs for a tablet-shaped getter could also be provided.
  • the coil which has an essentially rectangular cross section due to the inserted yoke legs 34a and 35a with the interposed permanent magnet 36, fills the upper space of the relay. It thus abuts the cap 53 on three sides, so that the winding heat is emitted well over the large outer surface.
  • the armature leg 37a is arranged below the coil between the contact elements, as a result of which the space below the coil is also used well. With its short bushings on the base body 46, the contact set requires only little space and therefore also offers the prerequisite for low contact circuit resistances.
  • FIG. 5 and 6 show in a further modification a base body 56, in which the contact elements are fastened by insertion.
  • the base body 56 has incisions 57 which are open from the side and into which the spring supports 58 and 59 and the mating contact elements 60, 61, 62 and 63 are inserted in the direction of the arrows 66.
  • a tight fit is achieved by integrally formed ribs 64.
  • the contact elements are designed similarly to the previously described embedded contact elements. They each have a pluggable middle part 58a, 59a, 60a, 61a, 62a and 63a as well as spring supports 58b and 59b or contact elements 60b to 63b bent upwards.
  • Terminal lugs 58c to 63c are again bent downward.
  • the fastening parts 58a to 63a each have cutouts 58d to 63d which are held on ribs 65 of the base body by an interference fit.
  • the base body 56 can be connected to the coil body 31 in the same way as the base body 46.
