Definitions

the invention relates to a switch according to the features of the preamble of claim 1.
Such a switch is known from DE-P 35 15 911.
the housing should not exceed certain external dimensions. For this reason alone, the arrangement of the plug contacts creates difficulties.
the plug contacts of each switch unit provided that they are to be embedded in a circuit board base plate, cannot have ends which are arranged in any way relative to one another if a simple holding tool is to be used during the method. In addition, complicated connector plugs would then be necessary, the correct connection of which to the plug contacts can be difficult.
the object of the invention is to provide a switch of the type mentioned, which is as simple and compact as possible and which can be safely connected to electrical components without difficulty.
the plug contact ends of the switch unit further lying in the plug-in direction can be protected from undesired contact.
such a frame can be used to assign the two switch units in the correct position and to ensure that a connector is installed in the correct position. It is pointed out that independent protection is claimed for this measure, since it can also be used with advantage in a switch in which the plug contacts are not embedded in the base plate material but are placed on the base plate.
the measure proposed in claim 13 can also prevent undesired bending of the plug contact ends.
the development according to claim 13 also enables a secure position Allocation of both switch units without additional aids. It is possible without difficulty to separate the switch units from one another, for example in order to be able to carry out repairs, by pulling the boards apart. It is pointed out that independent protection is also claimed for this measure, since it is also suitable for a switch in which the plug contacts are not embedded in the base plate material but are placed on the base plate.
the steering column switch shown completely in FIG. 1 has an approximately cylindrical tubular housing 10 with two switch units 11 and 12 arranged in superimposed levels.
the switch units 11 and 12 each have a circuit board 13 or 14, each having a base plate 15 or 16 made of plastic.
a multiplicity of conductor tracks 17 and 18 punched out from a sheet metal plate is cast.
Recesses 19 or openings 20 are provided in the base plates, through which a tool protrudes during the casting process, by means of which an exact position of the conductor tracks in the respective base plate is achieved.
the cutouts 19 and the openings 20 are indicated in FIG. 3.
the conductor tracks 17 have areas 21 which are to be understood as fixed contacts of the switch unit 11.
the conductor tracks 18 have areas 22 which are to be understood as fixed contacts of the switch unit 12.
the base plates 15 and 16 each carry a pin 23 or 24 on which a shift lever 25 or 26 is rotatably mounted and can be tilted about its longitudinal axis.
the shift levers 25 and 26 are made of plastic, but are reinforced by a metal insert 27 and 28 to increase stability.
the shift lever 25 is the wiper-washer shift lever, while the shift lever 26 is the turn signal and driving light switch lever.
the fixed contacts 22 of the switch unit 12 are arranged at different locations along the extent of the base plate 16 of the circuit board 14.
both the sections of the conductor tracks 17 to be regarded as plug contacts 33 of the circuit board 11 and the sections of the conductor tracks 18 to be understood as plug contacts 3 4 of the circuit board 14 are arranged in the same switch region 35.
the plug contacts 33 and 34 have ends 36 and 37, which are bent away from the respective base plate 15 and 16 at right angles and point downward. At these ends 36 and 37, the switch units 11 and 12 can be connected to the electrical system of the motor vehicle by guiding a connector, not shown, in the plugging direction 38.
the ends 36 of the plug contacts 34 of the switch unit 12, which is further away from the connector in the plug direction 38, run laterally from the ends 37 of the plug contacts 33 of the other switch unit 11 at a distance A from the perpendicular M, which is greater than the distance a between the ends 37 of the plug contacts 33 of the other switch unit 11 and the center perpendicular M.
the switch thus has a compactly designed switch connection area 35, in which the use of a single, compactly designed connector plug is possible.
the ends 36 of the plug contact 34 of the switch units 12 lying in the plug direction 38 further from the connector plug extend further outside than the ends 37 of the plug contacts 33 of the other switch unit 11, the ends 36 and 37 of the plug contacts 33 and 34 of both switch units 11 and 12 have none surfaces lying close together, so that great electrical safety is guaranteed.
the ends 36 and 37 of the plug contacts 33 and 34 of the switch units 11 and 12 are arranged opposite one another. As a result, a large expansion of the switch region 35 in the circumferential direction of the housing 10 is avoided.
the ends 36 and 37 of the plug contacts 34 and 33 of the two switch units 12 and 11 are each on a straight line 42. 41 arranged.
the ends 36 of the switch unit 12 are at a distance A 'from the longitudinal center plane E of the housing 10 which is greater than the distance a' between the ends 37 of the switch unit 11 and the longitudinal center plane E, as shown in FIG. 2.
the ends 36 and 37 of the plug contacts 34 and 33 of both switch units 12 and 11 all have the same distance b from one another on the longitudinal side surfaces 39 and 40, which corresponds to approximately half the extent of the ends 36 and 37 transversely to the longitudinal direction.
the ends 36 and 37 are thus arranged next to each other without risk of contact and yet compact.
the ends 36 of the plug contacts 34 of the switch unit 12, which is further away from the connector plug in the plug-in direction 38, are considerably longer than the ends 37 of the other switch unit 11. Nevertheless, they cannot be accidentally bent during the assembly of the connector plug are because they are embedded all around in a block 43 made of base plate material over the part of its length that is not inserted into the connector, which is bent at right angles from the other areas of the base plate 16. But also the ends 37 of the other switch unit 11 can not be bent unintentionally when mounting the connector, because they protrude into a frame 44 which has been made in one piece with the base plate 15 of the switch unit 11 and, as shown in FIGS. 2 and 4, a irregular, decagonal shape.
the base plate 15 of the switch unit 11 has a diameter d which is smaller than the diameter D of the switch unit 12 in the region of the outer surface 45 of the block 43.
the frame 44 is designed in such a way that it has an outer strip 46 which runs below the lower edge of the area 47 of the base plate 16 which lies to the side of the block 43.
the circuit board 13, as shown can be inserted with the block 43 into the frame 44, the block 43 and the frame 44 abutting one another closely in the area of the strip 46.
the frame 44 has a bar 48 which extends vertically up to the base plate 16.
the block 43 lies closely against the frame 44 over the entire height of the strip 48.
the block 43 also fits snugly on the other, not specified, side strips of the frame 44.
the frame 44 has a strip 49 which, viewed from the longitudinal center plane E of the housing 10, begins in front of the ends 37 of the plug contacts 33 and extends vertically downwards.
the frame 44 ends in the plug direction 38 everywhere in the same plane in front of the ends 36 and 37 of the plug contacts 34 and 33 of both switch units 12 and 11, which in turn all end in the same plane.
the strips 46 and 49 of the frame 44 each have at their lower ends a guide surface 50 and 51 for the connector.
FIG. 1 also shows, the block 43, in which the plug contacts 34 of the circuit board 14 are injected, ends in the same level as the base plate 15 of the switch unit 11 located closer to the connector plug 38 in the plug-in direction 38.
this enables a simple internal shape of the connector. Since the frame 44, as already mentioned above and as can be seen particularly from FIG. 4, has an irregular outline, it is recommended to use a connector plug which also has an irregular outline which is adapted to the inner outline of the frame 44. This ensures that the connector is always correctly installed.
the frame 44 extends completely within the outer contour 53 of the housing 10. Overall, a compact switch is thus created in which the external dimensions prescribed by the motor vehicle manufacturer are not exceeded and in which the two switch units 11 and 12, for example for repair purposes, can be easily detached from one another by simply pulling the boards apart.
