Definitions

  • the invention relates to a safety contact rail for power-operated systems and the like or a safety contact element as a switching hose and the like with an elastic Hollow profile, within which several strip-like, electrically conductive Protrusions are provided that are mutually non-conductive Cross sections are insulated, the conductive protrusions being mutual Touch to generate a switching pulse.
  • the object of the present invention is the generic safety contact rail or a safety contact element improve that there is always redundant contacting, and regardless of the direction in which the trigger force on the Safety contact rail or the safety contact element acts.
  • the object of the invention is achieved in that at least four strip-like, electrically conductive projections are provided and that these projections are uniform and even within of the hollow profile are distributed.
  • the cross-sectional areas the projections are preferably chosen and arranged so that they are point symmetrical to the central axis of the hollow profile run. It does not matter from which direction the force is applied on the safety contact rail or the safety contact element is initiated because there are always at least two projections touch each other and generate switching impulses against each other.
  • the cross-sectional areas of the projections are shaped so that they are essentially two right-angled triangles with different ones long legs can be defined. They exist of course not from two triangles, but they can be in corresponding ones Triangles divided and described thereby.
  • the Large triangles border the inner circumference with their hypotenuses of the hollow profile or form a partial circumference of the hollow profile itself, the hypotenuses are not designed as a straight line, but rather corresponding to the inner circumference of the hollow profile or the outer circumference of the hollow profile are curved.
  • the big triangles small triangles join in such a way that they align with the long ones Thighs of the large triangles ajar with their long thighs so that the short legs of the large and small triangles form a straight line.
  • strip-like noses attached, essentially in extension of the hypotenuses of the small triangles and the surfaces of the small legs tower over the small triangles.
  • This configuration of the Cross-sectional areas of the projections arise in the interior of the hollow profiles a cavity along the safety contact rail or the safety contact element, the one in the center by a square Cross-sectional area is defined, on the side faces of each one Edge then cavity strips are formed by the strip-like Noses are narrowed, being angled at these strips staggeredly connect further cavity strips up to the non-conductive Cross section of the hollow profile are sufficient. It became conscious small contact area, especially via the strip-like noses chosen. This leads to a high contact pressure, which leads to self-cleaning of the contact surfaces.
  • Carbon or graphite fibers can be incorporated.
  • the safety contact rail or the safety contact element can have two different types of non-conductive areas.
  • the sheath from not conductive material is made.
  • the cross sections the strip-like projections themselves part of the outer circumference of the hollow profile, with non-conductive sections between them are provided.
  • the outer circumference of the hollow profile completely non-conductive because of the non-conductive shell is surrounded, while in other cases conductive and non-conductive areas are provided which cover the outer circumference of the Form hollow profile.
  • the profile is also insensitive to external influences such as moisture and the like, because no "external contact" can take place.
  • the safety contact rail or the Safety contact element with the elastic hollow profile made of extrudable Material, especially rubber or polymers and in one piece including any embedded wires or strands preferably produced as an endless profile in an extruder, so that a homogeneous profile is created.
  • Hollow profiles can also be used 6 or 8 or more protrusions can be made and used.
  • connection side is then connected to a four-channel evaluator, ie to a connection line with four poles.
  • the safety contact element 2 according to FIG. 3 differs from Fig. 2 essentially in that no sleeve 5 is provided and that instead between the electrically conductive projections 6 electrically non-conductive sections 8 are arranged. Both the safety contact rail as well as the safety contact element extruded in one piece including the copper strands.
  • FIG. 7 to 9 are the two end cross sections of an arbitrarily long safety contact element, with the top and bottom lines connecting the two Profile cross sections represents the safety contact element. Left is reproduced the connection side and on the right is the connection opposite end of the safety contact element shown.
  • the copper strands of the conductive protrusions 6 are one above the other are arranged by parallel bracket 10 on the right Side of the figure interconnected.
  • On the left are the Connections that are connected to the copper strands there with a to d designated. They are all used when a four-way connection is chosen with the appropriate technology. Becomes a bipartite Connection selected, then the connections c and d via a Resistor 11 or a diode 12 bridges.
  • Fig. 8 differs from Fig. 7 only in that on the the end of the safety contact element facing away from the connection the copper strands 7 of the projections 6 diagonally over corresponding diagonal bridges 13 are interconnected. On the connection side can choose either two or four wire technology become.
  • Fig. 9 shows the same sketched safety contact element as that in Figs. 7 and 8, but with changed connections.
  • the four copper strands 7 are connected to one another via four diodes 12 or resistors 11 on the end opposite the connection, that is to say the right side of the figure.
  • On the left side all connections a to d are connected to a four-channel evaluator. Table "contact / angular force effect" in the circuit diagram according to Fig.
