Definitions

  • the invention relates to an electromagnetic relay with a Basic body, which each directly or indirectly Electromagnetic system with a coil, a core yoke and one Anchor, furthermore a contact arrangement which can be actuated by the anchor as well as connecting conductors for the contact arrangement and carries the coil, and with one that can be plugged onto the base body Cap, with at least part of the connecting conductor with cap connecting lugs led through the cap to the outside connected is.
  • Such a relay is known from EP-A2-0 409 613, in which the contact carriers each run through a base plate Solder pins and additionally through slots in one Housing cap tabs led to the outside exhibit. So that this flat connector when mounting the cap must be passed through the slots provided Extend the longitudinal axis in the direction of attachment; also need the slots in the cap match the game Ensure tolerance compensation. Because these tabs immediately are integrally formed on the contact carriers, one is also missing mechanical decoupling between the contact elements and the Flat connectors exposed to external insertion forces.
  • the aim of the present invention is to provide a relay of the input mentioned type constructively so that connection elements provided in the cap area on any side that can be easily attached to the cap, however no additional sealing problems in the Create a cap and, as far as contact connections are concerned, also mechanical decoupling from the actual ones Allows contact carriers.
  • this goal is achieved in that in the Cap electrically conductive connecting webs are attached, each one with one on the outside of the cap protruding cap connecting lug is connected and on the other hand forms a connector element inside the cap, which is a complementary connector element Connection conductor faces on the base body and with this comes into engagement by pushing on the cap.
  • cap connection elements are not with the base body or the connecting elements anchored in the base body in one piece or are firmly connected and so during assembly more or less generous openings in the cap be, but that these connecting lugs firmly with the Cap are connected and when they are mounted on the base body automatically contacted with the connecting elements there become.
  • this contact would even be conceivable to make this contact to be designed as a detachable plug connection. Basically however, this is not a plug connection, but about a more or less unsolvable connection in Form of clamping contacts that remain under permanent deformation with each other be engaged so that they are each other penetrate and form a permanent gas-tight connection.
  • the connector elements are after Type of insulation displacement connection permanently connected to each other, such as this for the connection contact of connectors is common.
  • the connecting webs can run along the inner surface of the cap and be fastened there with fastening sections. This can for example using thermoformed fastening pins, done by snap fasteners or otherwise.
  • the connecting webs at least partially embedded in the material of the cap his. In any case, the implementation of the cap connection lugs already during the manufacture of the cap by embedding or pre-assembling the cap connection lugs be tight as they are plugged in the cap on the body no relative movement between the cap connecting lugs and the cap itself is.
  • the cap tabs can either be used as additional connectors for the contacts or for the coil winding or also be provided as the only connections. Corresponding can the connecting conductors of the contact arrangement and / or Coil also additional, led outwards from the base body Form base connection lugs.
  • the relay shown in Figures 1 and 2 has one known structure with a base 1 on which a magnet system with a bobbin 2 as a carrier for a winding 3, further with a core 4, an angled yoke 5 and one Anchor 6 is arranged.
  • a base 1 on which a magnet system with a bobbin 2 as a carrier for a winding 3, further with a core 4, an angled yoke 5 and one Anchor 6 is arranged.
  • each contact lead 8 and 9 anchored, each to the underside of the base 1 Form emerging terminal lugs 10 (only one can be seen).
  • the Connection conductor 8 carries an invisible fixed contact, while the lead 9 via a strand 11 with a Contact spring 12 or one attached to the contact spring movable contact is connected.
  • the contact spring is with connected to the anchor and is in the usual way by this operated.
  • a cap 13 To allow tapping of the load circuit, for example for diagnostic queries, for a PCB connection or for other applications, are in a cap 13, the forms a closed housing with the base 1, in addition electrically conductive connecting webs 14 and 15 for the load circuit provided, each protruding to the outside of the cap Form tabs 16 and 17. Also are in the cap further connecting webs 18 and 19 with outwards Flat connectors 20 and 21 are provided as coil connections. All Link bars in the cap are along the inner surface guided and by means of hot stamped pin 22 or holding bars 23 attached. Each of the connecting bars has one fork-shaped clamping tab 24 with one in the push-on direction open cap clamping slot. The clamping tab 24 Crosspieces 14 and 15 lie exactly above the corresponding ones Terminal webs 25 of the connecting conductors 8 and 9, so that they with these each with an insulation displacement connection when the cap 13 is attached come in.
  • the two insulation displacement sections 26 each lie on fork-shaped supports 29 of the base 1 so that when pressing the associated Clamping tab 24 can withstand the pressure, so that a firm and permanent insulation displacement connection is created.
  • the coil winding 3 thus only connections via the connecting webs 18 and 19 and the tabs 20 and 21, while the contacts both via base connection lugs 10 and via cap connection lugs 16 and 17. If necessary, of course additional coil connection elements are also provided in the base become.
  • the cap 13 snaps over locking tabs 30 on corresponding locking bars 31 of the base. In this way, too Insulation displacement connections between the connecting webs 14, 15, 18, 19 and the corresponding contact leads 8 and 9 as well as the winding supports 27 and 28. Instead of the subsequent attachment of the connecting webs shown 14, 15, 18 and 19 on the inner surface of the cap 13 but it is also possible to include these connecting bars embedding the cap in its walls.
  • FIG 4 is a circuit diagram of the relay shown with shown its connections. It can be seen from this that the Load circuit of the contact leads 8 and 9 each over parallel socket connector lugs 10 and cap connector lugs 16 or 17 can be connected while the coil circuit the winding 3 via the winding supports 27 and 28 only connected to the cap terminal lugs 18 and 19 can be.
