Definitions

  • the invention relates to a switching device for actuating Valves, with electrically mass-leading parts, such as a housing and a therein arranged bobbin, in which a pole tube with switching part and which is provided with a winding of a conductor by means of a connection device can be connected to a power source.
  • Such switching devices are known and freely available on the market. If the conductor winding of the switching device with a current or Connected to the voltage source, the excitation of the coil turns the switching part, this is also referred to as a magnet armature and can be moved longitudinally in the pole tube is arranged, operated and against the force of a spring accumulator or the like. a valve is opened, mostly when switching off the power supply the influence of this energy accumulator, the switching part in its unactuated rest position moved back.
  • the connection device has in the known Switching devices on two connecting pins that are comparable in function a plug for establishing the power connection in a power supply system are insertable.
  • the object of the invention based on improving this known switching device so that for a Operator any danger when handling the switching device due to an electric shock.
  • This Security also includes a possible replacement process in which the pole tube with the switching part remains with the valve device and the housing with the bobbin and the connecting device from the pole tube by hand Will get removed.
  • the contacting has a roll pin, which in a Hole can be used on the rear wall of the housing and with a Overhang in the for guiding the pole tube within the device provided recording space protrudes. Due to the internal tension of the dowel pin this ensures secure contacting that goes beyond that is inexpensive to manufacture.
  • the switching device is explained in more detail below with reference to the drawing.
  • the switching device has a housing 10 made of a metallic, electrically conductive material.
  • a coil former 12 arranged, in turn in the usual and therefore not shown as well as described a pole tube with switching part is.
  • the coil former 12 is provided with a conductor winding 14, the Conductor of the winding by means of a connection device 16 to a power source (not shown) can be connected.
  • the connection device points for the connected to a power source, two contacts in the form of Connection pin 18 on.
  • the switching device can end and to the recording room 20 facing sealant for the pole tube, for example in the form of an O-ring 22.
  • at least the conductor winding 14 be cast or extrusion-coated with a plastic compound 24.
  • the contact shows one Roll pin 28 as shown in Figures 5 and 6, in the kind of a ferrule is formed.
  • Existing metal dowel pin 28 can be a standard part, according to the DIN standard 7346 and have ends 30 chamfered at an angle of 30 °.
  • the roll pin 28 is hollow-cylindrical and has a longitudinal slot 32 Mistake.
  • the dowel pin 28 can be made using suitable and known handling tools along its adjacent, delimiting the longitudinal slot 32 Press the edges together and into a longitudinal hole provided for this purpose Insert 34 in the rear wall 36.
  • the spring pin 28 is then fixed under the internal stress of the spring steel to the bore wall and stands with a certain protrusion in the for the receiving tube 20 provided the pole tube.
  • This supernatant can be best seen in Fig.5.
  • the longitudinal slot 32 is in the inserted state of the dowel pin 28 arranged facing downwards and with in FIG a double arrow angle between the longitudinal axis of the longitudinal slot 32 and the vertical through the center of the dowel pin 28 is approx. 45 °.
  • the supernatant is preferably selected on the one hand in such a way that always secure contact between housing 10 and pole tube (not shown) is manufactured; on the other hand, the retraction of the pole tube in the receiving space 20 is not difficult.
  • the mentioned longitudinal bore 34 is so arranged in the rear wall 36 that the receiving space 20 there remains an opening which is circumferential of the dowel pin 28 can be closed with its overhang. If the longitudinal slot 32 with the points addressed angle in the direction of the receiving space 20, can under the influence of the pole tube to be inserted, the two free ends of the Dowel pin 28, which limit the longitudinal slot 32, relatively easily against each other move, but at all times secure contact with the pole tube is reached.
