Definitions
- the invention relates to an electromagnetic relay with a a housing comprising a cap, one arranged in the housing Magnetic system with a coil and one along the Coil outside arranged around a pivot axis in the area the coil center pivoted armature and with a connected to the anchor through an operating window the cap of the actuator accessible from the outside.
- Such a relay is for example from DE-A1-36 24 783 known.
- a polarized relay system shown with a so-called H-anchor, in which an operating lever arranged in the extension of an anchor leg and with a lateral offset through an opening of the housing comes out.
- the relay there has a very large height because the coil axis and the Anchor perpendicular to the bottom side or installation level of the relay stand so that the operating lever on the top of the housing is accessible.
- the system is rotated 90 ° to achieve this a flat design, however, would be the actuating lever emerge from a side wall, which is accessibility would complicate on a circuit board.
- the aim of the present invention is to provide a relay of the input to design the type mentioned with an actuator in such a way that unfavorable force effects on the anchor bearing, avoided, which could lead to lifting of the anchor become.
- this goal is achieved in that the Actuator at least one near the pivot axis of the anchor from its surface approximately perpendicular has outwardly projecting switch cams.
- the actuator has a single switch cam in the form of a rocker arm, which is in the radial direction to the pivot axis of the armature extends outwards. So the anchor is exactly over its center and above its pivot axis by a rocker arm operated. Basically, however, the actuator also be designed as a rocker, the actuation by Pressure on the respective wing of the seesaw and thus on the respective anchor wing.
- This seesaw can as well the rocker arm as a one-piece actuator, for example made of plastic and on the anchor by plug or the like. But it can also Anchors themselves form the seesaw, then two separate ones Switch cams on both sides at a distance from the axis of rotation Anchors are attached. If you leave one of these switch cams away, so there is a one-sided actuator for the If it is a monostable magnet system, where the armature by a magnet or by spring force automatically reset to the same rest position becomes.
- the actuator each in the direction of the switching movement the respective switch cam carries markings, depending on Switch position different markings through a window the cap are visible.
- This window can each be an area of the operating window or as an additional window separated from the operating window in be spared the cap.
- the relay shown in Figure 1 has a known per se Magnet system with a hidden in a base body 1 Coil 2 with an axis parallel to the bottom side, with a core arranged inside the coil, the ends of which are connected with two yokes 3 and 4. Between the ends the two yokes 3 and 4 is a plate-shaped permanent magnet 5 arranged parallel to the coil axis.
- the permanent magnet is magnetized three-pole, the two outer poles with the yokes 3 and 4 are coupled, while on the center pole a rocker armature 6, the two wings of which are blunt to each other Form angle, is mounted rollable.
- an anchor spring 7 serves an anchor spring 7.
- the anchor 6 forms with the two yokes 3 and 4 each have an air gap, so that it each not in the middle position shown in the idle state stands, but optionally on one of the yokes 3 or 4 is held.
- a corresponding current pulse in the armature of this bistable system is switched over the coil.
- additional spring force or by asymmetrical adjustment of the permanent magnet 5 to achieve monostable switching behavior.
- a contact system 9 switched; this is not meant to be detailed here be carried out. Otherwise the relay system is in one formed by a base plate 10 and a cap 11 Housing housed.
- the armature is for additional manual actuation of the relay 6 provided with an actuator 12 which is centered on the anchor sits over the bearing area and a radial to Bearing shaft protruding outwards in the form of a Has rocker arm 13.
- the actuator 12 is with the Anchors firmly connected, for example by fastening pins 14, which are inserted into recesses 15 of the armature. It but would also be conceivable, the actuator by injection molding or to connect to the anchor in a similar manner. It would also be conceivable for an actuator to be integral with the Form anchors by appropriate shaping.
- the rocker arm protrudes to enable external actuation 13 through an actuation window 16 of the housing cap 11.
- This actuation window is dimensioned in such a way that that the rocker arm 13 in both directions in the longitudinal direction of the armature as far as the anchor can move its respective Has reached the end position.
- At the position of the rocker arm in the operating window 16 is also the respective one Switching status of the relay recognizable.
- To be proportionate to reach long lever arm for the rocker arm 13 extends the actuator in the example of FIG an approach 12a in a bulge 11a of the cap 11. This the switching path of the rocker arm 13 is longer, and the switch positions differ more clearly from each other. If this is not necessary or if the permissible Height of the relay does not allow this can also be done with a shorter lever arm for the rocker arm 13 can be worked.
- FIG. 2 shows a slightly modified embodiment, which in particular, waived any increase in the overall height.
- the relay system shown in perspective in FIG. 2 is basically constructed exactly as in Figure 1. Only that Actuator has been modified. This now consists of two separate switching cams 17 and 18, which on separately the anchor, for example by attaching, are attached. Each of the switching cams 17 and 18 protrudes into its own actuation window 19 or 20 without over the surface of the cap 11 survive. The two switching cams 17 and 18 could but also be part of a common actuator that is attached to the anchor as in Figure 1.
- the lever arm is removed by removing the two switching cams 17 and 18 formed by the armature axis of rotation; the anchor itself forms the rocker switch.
- the actuation in this case is not carried out by a shift a lever in the longitudinal direction of the armature, but by pressure on one of the switching cams 17 and 18 from the outside in the direction approximately perpendicular to the anchor surface.
- the area 21 is between the two operating windows 19 and 20 reset inwards.
- the switching state of the relay is in this case at the respective height position of the two switching cams 17th and 18 to recognize.
- Figure 3 shows the same structure as Figure 2, only the one switching cam 17 and the corresponding actuation window 19 are omitted, so that only one, in Distance from the axis of rotation of the armature 6 engaging switch cams 18 is present.
- the magnet system is monostable so that due to magnetic or spring forces, the armature at rest is attracted to the yoke 3.
- a manual operation can in this case only by the switching cam 18 in the direction be made on the yoke 4.
- FIGS. 4 and 5 show a relay structure according to FIG 1, the cap 11 closed and only in the area of the actuator shown cut open, the visualization represented by a marker.
- On the approach 12a of the Actuator 12 are on both sides of the rocker arm 13 each Markers with dark areas 22 and light ones Areas 23 are provided. These are check boxes in the drawing enlarged to emphasize. In reality it is only a question of colored surface layers on the actuator 12, the side view hardly would be visible. In practice, for example dark area 22 each red and light area 23 each be white or black. It just comes suggest that there is a contrast between the two areas in color or brightness on the top of the relay becomes visible.
- Above the check boxes are in the Housing cap 11 each provided viewing window 24 and 25. These viewing windows 24 and 25 are kept as narrow as slots, that depending on the switch position only the marking areas 22 or the different colored marking areas 23 are visible.
- the operating window 16 can be used for position detection.
- the window area 16a would open one side of the rocker arm 13 or the window area 16b on the other side of the rocker arm 13 the function of a Get viewing window if below the actuation window 16 the actuator 12 colored markings, and on both sides of the rocker arm 13 in different Color, would get.
