Definitions

  • the invention relates to a position signaling changes and accelerations of its housing switch with the features of the preamble of claim 1.
  • Such switches are known per se. They are used, for example, in motor vehicles, where they are intended to trigger a switching operation when a predetermined limit value for acceleration or deceleration is exceeded, for example switching on an optical or acoustic signal, inflating a so-called “airbag” or the like. or acceleration-sensitive sensor on a mercury switch, in which a movably mounted small amount of mercury short-circuits two electrodes when a predetermined limit value is exceeded.
  • Changes in position and accelerations of the switch housing cause a movement of the permanent magnet relative to the reference system of the switch housing and in this way cause a change in the switching state of the reed switch which is fixedly attached to the switch housing at certain limit values of changes in position or acceleration.
  • the invention has for its object to develop the known position and acceleration sensitive switch with a movable permanent magnet and at least one reed switch as active elements, with the aim of simplifying their structure, increasing their response accuracy and their on and off hysteresis to reduce. This object is achieved by the combination of features of claim 1.
  • the switch responds on the one hand even at relatively low accelerations or decelerations, that is to say it is highly sensitive.
  • the reed switch acts due to its longitudinal orientation in the direction of vibration with its magnetizable parts as a magnetic brake and proportionally also as eddy current damping, so that wild vibrations of the pendulum-suspended magnet are suppressed.
  • the orientation of the reed switch also enables the space-saving construction of the switch housing that accommodates the reed switch and the permanent magnet.
  • the swivel range of the pendulum must be taken into account when dimensioning the switch housing anyway. No additional space is therefore required for the longitudinal orientation of the reed switch.
  • the reed switch Transversely to its longitudinal orientation, the reed switch can also be installed pivoted by a certain angle by an imaginary extension of the pendulum longitudinal axis which is in the rest position, without impairing the narrow construction of the switch housing.
  • Claim 2 ensures the necessary influence on the switching state of the reed switch by the special arrangement of the permanent magnet.
  • the magnetization direction lying in the pendulum plane continues to support the narrow construction of the switch housing in the case of a large number of embodiments of permanent magnets.
  • Claims 3 and 4 relate to advantageous arrangements of polarization direction of the permanent magnet and longitudinal axis of the reed switch.
  • the hysteresis of the magnetizable parts of the reed switch is further reduced, so that an improvement in the response accuracy and responsiveness of the switch is achieved.
  • the improved response characteristics of the switch enable the permanent magnet to have a shorter swivel path along its pendulum level in order to still achieve sufficient response accuracy and fineness.
  • the shorter swivel path in turn enables a shorter pendulum length.
  • the required volume of the switch housing is further reduced.
  • the permanent magnet is a bar magnet.
  • Bar magnets can be produced in very small dimensions, so that they are particularly suitable for the application proposed here. All known magnetic materials can be used.
  • Claims 6 and 7 enable an effective fixation of the permanent magnet within the switch housing. This ensures that the permanent magnet performs the required oscillations.
  • the pendulum frame is easy and inexpensive to manufacture. Since the pendulum frame has a certain degree of mechanical stability, wild vibrations of the permanent magnet can be dampened.
  • the pendulum housing for the permanent magnet is preferably formed on the end region of the pendulum frame facing the reed switch. As a result, the center of gravity of the pendulum is very low, so that its damping properties are further improved.
  • the deep arrangement of the pendulum housing also enables the reed switch to be better influenced by the permanent magnet.
  • the mass of the pendulum frame and the pendulum housing itself also act as damping for the pendulum vibrations.
  • pendulum properties such as e.g. Achieve tripping characteristics and damping. Coordinates of the center of gravity can be changed using differently shaped mass bodies. As a result, the pendulum properties can also be changed in a simple manner.
  • mass body and permanent magnet are mechanically stable fixed.
  • the days of such a pendulum are also simplified.
  • the proposed switch as an easy-to-use component, it is proposed according to claim 11 that the above-mentioned functional parts, namely the pendulum frame together with permanent magnet and possibly additional mass body on the one hand and the reed switch on the other hand are combined in a switch housing to form a structural unit.
  • This switch housing is equipped according to claim 12 with connecting elements in the form of plug pins, solder pins or cables, so that the entire switch can be arranged as a functional part on printed circuit boards or in other electrical or electronic circuits.
  • the simple bending of the connector pins or soldering pins enables the switch housing to be brought into a desired inclined position relative to the printed circuit board or other mounting supports.
  • the switch is therefore also effective as a tilt switch and triggers various functions at very specific tilt positions.
  • a plurality of switch housings which already form a functional unit, with an integrated pendulum frame, permanent magnet, optionally additional mass bodies and associated reed switches are arranged in a common protective housing.
  • the functional units have pendulum planes aligned parallel to one another, the individual switches, however, being arranged in different angular positions with respect to the base plate of the protective housing.
  • a narrow construction of the individual switch is advantageous in order to be able to keep the overall volume of the protective housing itself small.
  • the claims 15 and 16 relate to advantageous ways to achieve different inclination or angular positions of individual switches with technically simple means.
  • the switch housing is preferably fixed to the fixing axis by friction in order to enable mechanically stable fixing.
  • the individual functional units or switches are arranged in a protective housing in different spatial directions, so that inclinations, accelerations or decelerations in different directions can be measured or at least detected with the overall element. In this way, a whole cascade of differently sensitive switches can be formed.
  • Such switch combinations can also be used, for example, as threshold value transmitters for an ABS system in motor vehicles.
  • Claim 18 relates to a measure for the mechanically stable final fixation of the switches arranged in a protective housing. As a result, the geometric alignment of the pendulum level of a switch is always retained. This ensures that certain functions are triggered at the initially set limit or threshold values over the entire service life of the switches.
  • the switch housing is filled with damping fluid.
  • damping fluid The effectiveness of the damping depends on both the amount and the viscosity of the damping fluid.
  • Claim 20 enables an inexpensive and simple manufacture of the switch housing.
  • the switch housing can be easily installed without additional aids, such as additional connecting elements.
  • Fig. 1 the switch 1 can be seen with a housing shell acting as a bottom shell 2.
  • the bottom shell 2 has approximately the shape of an isosceles triangle. However, the connection area of the two triangle legs opposite the base side is rounded off in the manner of a circular arc.
  • a pendulum frame 3 is fixed in place on a pendulum axis 4.
  • the pendulum frame 3 is pivotally suspended in the switch housing by means of the pendulum axis 4.
  • a pendulum housing 6 is integrally formed on the pendulum frame 3.
  • the pendulum frame 3, starting from the pendulum axis 4 in the direction of the pendulum housing 6, has a conically expanded outline shape.
  • a mass body 8 is inserted in a form-fitting manner in the receiving space 7 of the pendulum housing 6.
  • the mass body 8 has a square outline shape in FIG. For example, it can be a brass block.
  • mass body 8 with the same dimensions, but different masses, the damping behavior of the pendulum frame 3 can be varied.
  • the pendulum housing 6 is penetrated on one side by a through hole 10 in a longitudinal direction 9 of the switch 1.
  • the mass body 8 is partially penetrated by a fixing bore 11 running in the longitudinal direction 9. It extends somewhat along the longitudinal direction 9 beyond the longitudinal longitudinal axis 12 which runs parallel to the vertical direction 5.
  • the through bore 10 and the fixing bore 11 are congruent when viewed in the longitudinal direction 9 and serve for the positive reception and fixing of a permanent magnet 13 designed as a cylindrical bar magnet.

  • the longitudinal axis 16 and the pendulum longitudinal axis 12 are arranged perpendicular to one another.
  • the reed switch 15 is located approximately equally on both sides of the longitudinal axis 12 of the pendulum.
  • the reed switch 15 is fixed with its connecting wires 17 to clamping projections 18 of the base shell 2.
  • the clamping projections 18 are preferably integrally formed on the base shell 2 and extend parallel to the depth direction 19 into the interior 21 of the switch housing delimited by the base shell 2 and a cover shell 20 (FIG. 2).
  • the connecting wire 17 is clamped between the two circular clamping ends of a clamping projection 18 in FIG.

In the area of this angle, the outer edge of the shell boom 22 is rounded. In this area, the shell arm 22 is initially rectangular in the height direction 5 and then cut immediately thereafter as a circular switch bearing 23. The switch bearing 23 breaks through the shell arm 22 in the depth direction 19 (FIG.

  • the wire bore 26 of the cover shell 20 is provided for the second connecting wire 17. If the switch 1 is soldered to the ends of its connecting wires 17 on a printed circuit board, the inclination of the base wall 14 and thus of the entire switch 1 can be adjusted or changed by pivoting about an imaginary pivot axis penetrating the wire bore 26 in the depth direction 19.
  • a bearing plate 27 fixed to the base shell 2 and to the cover shell 20 is provided for the pivotable mounting of the pendulum axis 4 (FIG. 2).
  • the bearing plates 27 are arranged parallel to one another and run in the height direction 5. They rest directly on projections projecting into the interior 21 and are fixed in place on two cylindrical fixing pins 28.

  • the reed switch 15 is integrated in the base wall 14 of the base shell 2. Its longitudinal axis 16 runs perpendicular to the longitudinal axis 12 of the pendulum. However, the longitudinal axis 12 of the pendulum and the direction of polarization of the permanent magnet 13 are not perpendicular to one another as in FIG. 1, but form an acute angle.
  • the mass body 8 and the permanent magnet 13 are fixed side by side in the pendulum housing 6.
