Definitions

the aim of the present invention is to construct a relay of the type mentioned at the outset in such a way that connecting elements can be provided in the cap area on any side, which ensure that the cap can be simply plugged on, but do not create any additional sealing problems in the cap and, insofar as possible are contact connections, also enables mechanical decoupling from the actual contact carriers.
this aim is achieved in that electrically conductive connecting webs are fastened in the cap, each of which is connected on the one hand to a cap connecting lug projecting to the outside of the cap and on the other hand forms a plug-in connection element inside the cap, which faces a complementary plug-in connection element of a connecting conductor on the base body and engages with this by pushing on the cap.
cap connection elements are not integrally or fixedly connected to the base body or the connection elements anchored in the base body and are thus inserted during assembly through more or less generously dimensioned openings in the cap, but rather that they are Connection lugs are firmly connected to the cap and are automatically contacted with the connection elements there when they are mounted on the base body. It would even be conceivable to design this contact as a detachable plug connection. Basically, however, it is not a plug-in connection, but a more or less non-detachable connection in the form of clamping contacts which are brought into engagement with one another under permanent deformation, so that they penetrate one another and form a permanent gas-tight connection.
the plug-in connection elements are therefore preferably inseparably connected to one another in the manner of an insulation displacement connection, as is customary, for example, for the connection contacting of plug-in connectors.
the connecting webs can run along the inner surface of the cap and can be fastened there with fastening sections. This can be done, for example, by means of thermoformed fastening pins, by snap fastenings or in some other way.
the connecting webs can be at least partially embedded in the material of the cap.
the cap connecting lugs can be carried out Already in the manufacture of the cap by embedding or during the pre-assembly of the cap connection lugs, since no relative movement between the cap connection lugs and the cap itself is required when the cap is attached to the base body.
the cap connecting lugs can either be provided as additional connections for the contacts or for the coil winding or as the only connections.
the connection conductors of the contact arrangement and / or the coil can also form additional base connection lugs which lead outward from the base body.
the complementary plug-in connection elements are arranged on the base body in relation to the plug-in connection elements of the cap, these can of course also be anchored in a coil body fixedly arranged on the base body. It would also be conceivable that a coil body itself forms a base body carrying the connecting conductors for the contacts.
the relay shown in Figures 1 and 2 has a known structure with a base 1, on which a magnet system with a coil body 2 as a carrier for a winding 3, further with a core 4, an angled yoke 5 and an armature 6 is arranged.
a base 1 or one with it connected side wall 7 contact connecting conductors 8 and 9 are anchored, each forming connection tabs 10 (only one to see) emerging to the underside of the base 1.
the connecting conductor 8 carries a non-visible fixed contact, while the connecting conductor 9 is connected via a wire 11 to a contact spring 12 or a movable contact fastened to the contact spring.
the contact spring is connected to the armature and is actuated by it in the usual way.
connecting webs 14 and 14 in a cap 13 which forms a closed housing with the base 1 15 provided for the load circuit, which each form tabs 16 and 17 protruding toward the outside of the cap.
additional connecting webs 18 and 19 are provided in the cap with outwardly guided tabs 20 and 21 as coil connections. All connecting webs in the cap are guided along the inner surface and fastened by means of hot stamped pins 22 or holding webs 23.
Each of the connecting webs has a fork-shaped clamping tab 24 with an insulation displacement slot which is open in the plug-on direction of the cap.
the clamping tabs 24 of the connecting webs 14 and 15 lie exactly over corresponding clamping webs 25 of the connecting conductors 8 and 9, so that they each enter into an insulation displacement connection when the cap 13 is attached.
clamping tabs 24 of the connecting webs 18 and 19 for the coil connections come to lie accordingly over clamping sections 26, which are each part of two winding supports 27 and 28 for the ends of the winding 3.
the two insulation displacement sections 26 each lie on fork-shaped supports 29 of the base 1 so that they press on the associated ones Clamping tab 24 can withstand the pressure, so that a firm and permanent insulation displacement connection is created.
the coil winding 3 therefore only has connections via the connecting webs 18 and 19 and the flat plugs 20 and 21, while the contacts have both base connection lugs 10 and cap connection lugs 16 and 17. If necessary, additional coil connection elements could of course also be provided in the base.
the cap 13 engages via latches 30 on corresponding latching webs 31 of the base. In this way, the insulation displacement connections between the connecting webs 14, 15, 18, 19 and the corresponding contact connecting conductors 8 and 9 and the winding supports 27 and 28 are also secured. Instead of the subsequent attachment of the connecting webs 14, 15, 18 and 19 shown on the inner surface of the cap 13, it would also be possible to embed these connecting webs in the walls of the cap during the manufacture of the cap.
FIG. 4 shows a circuit diagram of the relay shown with its connections. From this it can be seen that the load circuit of the contact connecting conductors 8 and 9 can be connected in each case via parallel socket connecting lugs 10 and cap connecting lugs 16 and 17, while the coil circuit of the winding 3 via the winding supports 27 and 28 can only be connected to the caps -Connection lugs 18 and 19 can be connected.
